Given that eight bags of grapes cost twenty dollars, the cost of 3 bags of grapes will be $7.5.
How much do 3 bags of grapes cost?Given that;
8 bags of grapes cost $20.00
First, we find how much each bag of grape cost
8 bags = $20.00
1 bag = x
x = $20.00 / 8
x = $2.5
Now, if 1 bag of grapes cost $2.5
3 bags of grapes will cost y
y = 3 ×$2.5
y = $7.5

The Story of Ben and Arthur- Both save $500 per month at 11% compounded monthly. Ben starts at age 19 and stops at age 26, while Arthur starts at age 27 and stops at age 65.
Answer:
Results are below.
Step-by-step explanation:
It is not clear what the question is. But, I will assume that we need to calculate the future value of each investment at age 65.
First, we need to calculate the future value of the monthly deposit made by Ben. We will use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= 500
Interest rate (i)= 0.11/12= 0.0092
Number of months (n)= (26 - 19)*12= 84
FV= {500*[(1.0092^84) - 1]} / 0.0092
FV= $62,944.74
Now, the future value of the investment of Ben at age 65:
FV= PV*(1 + i)^n
n= (65 - 26)*12= 468 months
FV= 62,944.74*(1.0092^468)
FV= $4,574,131.31
Finally, the future value of the investment for Arthur:
i= 0.0092
n= (65 - 27)*12= 456
A= 500
FV= {500*[(1.0092^456) - 1]} / 0.0092
FV= $3,484,032.07
All sides of the convex pentagon $ABCDE$ are of equal length, and $\angle A = \angle B = 90^\circ$. What is the degree measure of $\angle E$?
Answer:
∠E = 150°
Step-by-step explanation:
All sides of the convex pentagon ABCDE are of equal length, and ∠A = ∠B = 90°. What is the degree measure of ∠E?
Solution:
A pentagon is a polygon with five sides and five angles. For a regular polygon, all the sides are equal and each angle is 108°.
Since ∠A and ∠B are right angles, and AE = BC = AB = CE. Therefore ABCE is a square. This means ∠AEC = 90°
Also triangle CDE is equilateral because all sides of the triangle are equal, hence ∠DEC = 60°.
Therefore ∠E = ∠AEC + ∠DEC = 90° + 60°
∠E = 150°

Mr. Howard planted a new garden. The garden is 15 feet long and 4 feet wide. What is the perimeter of mr. Howard's garden?
Answer: 38 feet
Step-by-step explanation:
Based on the dimensions of the garden, we can infer that it a rectangular garden because one side is longer than the other.
The perimeter of a rectangle is calculated as:
= (2 * length) + (2 * width)
= (2 * 15) + (2 * 4)
= 30 + 8
= 38 feet
4. Up until the last game, Sellina has made 75% of her free-throws. If she continues
to make her free-throws at this rate, what is the probability that she will make the
next two free-throws in the next game?
Answer:
0.5625 = 56.25% probability that she will make the next two free-throws in the next game.
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either Sellina makes it, or she misses. The probability of making a free throw is independent of any other free throw. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
75% of her free-throws.
This means that [tex]p = 0.75[/tex]
What is the probability that she will make the next two free-throws in the next game?
This is P(X = 2) when n = 2. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.75)^{2}.(0.25)^{0} = 0.5625[/tex]
0.5625 = 56.25% probability that she will make the next two free-throws in the next game.

In a 3-digit number, the hundreds digit is one more than the ones digit and the tens digit is twice the hundreds digit. If the sum of the digits is 11, find the number. Write and equation, where the hundredths digit is x.
Answer:
The mentioned number in the exercise is:
362Step-by-step explanation:
To obtain the mentioned number in the exercise, first you must write the equations you can obtain with it.
If:
x = hundredths digity = tens digitz = ones digitWe can write:
x = z + 1 (the hundreds digit is one more than the ones digit).y = 2x (the tens digit is twice the hundreds digit).x + y + z = 11 (the sum of the digits is 11).Taking into account these data, we can use the third equation and replace it to obtain the number and the value of each digit:
x + y + z = 11(z + 1) + y + z = 11 (remember x = z + 1)z + 1 + y + z = 11z + z +y + 1 = 11 (we just ordered the equation)2z + y + 1 = 11 (z + z = 2z)2z + y = 11 - 1 (we passed the +1 to the other side of the equality to subtract)2z + y = 102z + (2x) = 10 (remember y = 2x)2z + 2x = 102z + 2(z + 1) = 10 (x = z + 1 again)2z + 2z + 2 = 104z + 2 = 104z = 10 - 24z = 8z = 8/4z = 2Now, we know z (the ones digit) is 2, we can use the first equation to obtain the value of x:
x = z + 1x = 2 + 1x = 3And we'll use the second equation to obtain the value of y (the tens digit):
y = 2xy = 2(3)y = 6Organizing the digits, we obtain the number:
Number = xyzNumber = 362As you can see, the obtained number is 362.

Answer:
-44.35
Step-by-step explanation:
1/4 = 0.25 (as 0.25 * 4 = 1)
-25 1/4 = -25.25
-25.25 - 19.1 = -44.35
The value is -44.35.
What is simplification?The process of replacing a mathematical expression with one that is equivalent, simpler, and typically shorter. Examples of simplification include simplifying algebraic expressions in computer algebra, simplifying Boolean expressions in logic optimization, and simplifying fractions by using conjunction elimination in logic inference to produce a formula that is simpler but typically not equivalent to the original.
Given [tex]-25\frac{1}{4}[/tex] - 19.1
[tex]-25\frac{1}{4}[/tex] can be written as -(25 + 1/4)
1/4 multiply and divide by 25
we get 25/100
to convert fraction into decimal make the base multiple of 10 and put decimal ahead the no. of digits
20/100 = 0.25
equation is -25.25 - 19.1 = -44.35
Hence the value is -44.35.

The most Stanley can afford to pay per year in mortgage payments is $12,000, and his credit score is currently 544. According to the following table for a $150,000 mortgage, by how many points would he need to improve his credit score in order to take a mortgage for $150,000? FICO Score 720-850 700-719 675-699 620-674 560-619 500-559 Interest Rate 5.59% 5.71% 6.25% 7.40% 8.53% 9.29% Monthly Payment $860 $872 $924 $1,039 $1,157 $1,238 O A. 156 points OB. 131 points O C. 76 points O D. 14 points
The answer is not listed in the options. The credit score points are 170.
What is a credit score?To determine the answer, we need to find the interest rate and monthly payment associated with Stanley's credit score of 544.
Since Stanley's credit score is not listed in the table, we need to estimate the interest rate and monthly payment based on the information provided. Generally, the lower the credit score, the higher the interest rate and monthly payment.
Let's assume that Stanley's interest rate would be 10% and his monthly payment would be $1,000 based on his credit score of 544.
Using the table, we can see that for a $150,000 mortgage with a 10% interest rate, the monthly payment would be $1,316.
Now, we need to determine how much Stanley can afford to pay per year in mortgage payments, which is $12,000. We can divide $12,000 by the monthly payment of $1,316 to get the number of payments he can make in a year: $12,000 ÷ $1,316 = 9.12 payments.
Since there are 12 months in a year, Stanley can only make 9 payments per year. Therefore, he can only afford a mortgage with 9 payments of $1,316, which is $11,844 per year.
To afford a $150,000 mortgage, Stanley would need to lower his interest rate or increase his monthly payment. Since he cannot afford a higher monthly payment, he would need to improve his credit score to lower his interest rate.
Looking at the table, we can see that the interest rate associated with a credit score of 675-699 is 6.25%, which would result in a monthly payment of $924. To afford a $150,000 mortgage with a monthly payment of $924, Stanley would need to improve his credit score by 544 - 675 + 1 = 170 points.
Therefore, the answer is not listed in the options.

Answer:
The initial arm of an angle rotates to its terminal position, either in a positive, counterclockwise direction or a negative, clockwise direction. The principal angle is the first positive angle less than 360°.
The positive angle formed when an angle is in a standard position is called principal angle.
An angle is formed at the point where two or more lines meet. And it is said to be in a standard position if its edge is located at to the origin with its initial arm in line with the horizontal axis. The initial arm of an angle is the side with which the angle is measured from, while the terminal arm is the side on which the measure of an angle terminates. Thus, angles are normally measured from there initial arm to the terminal arm.
Therefore, the first positive angle formed between the initial and terminal arm of an angle in a standard position is usually called the principal angle.

A card is drawn at random from an ordinary pack of playing cards. What is the probability that it is neither a face card nor a black card? 16/52 = 4/13 10/52 = 5/26 14/52 = 7/26 20/52 = 5/13
20 / 52 = 5 / 13
Step-by-step explanation:
Probability(P) is the likelihood of occurrence of an event. It is given by;
P = total number of favourable outcomes ÷ total number of possible outcomes
In a pack of playing cards, there are 52 cards altogether.
Therefore, the total number of possible outcomes = 52
To get the probability that a card drawn at random is neither a face nor a black card, the following should be noted.
i. There are 12 face cards in the pack. These are the kings (4 cards), queens(4 cards) and the jacks (4 cards).
Therefore, number of cards that are not face cards = 52 - 12 = 40
ii. Black cards are half of the total number of cards = 26.
These black cards contain half of the kings, queens and jacks cards = 6 which are already included in the face cards. Therefore, the remaining black cards will be 26 - 6 = 20
Neither a face card nor a black card = 40 - 20 = 20 [number of favourable outcomes]
The probability of getting neither a face card nor a black card is
=> total number of favourable outcomes ÷ total number of possible outcomes
=> 20 / 52 = 5 / 13

Eli wanted to order candy online. Company A is offering 2 12 pounds of chocolate for $32.50. How much is Company A charging per pound of chocolate?
Answer:
Step-by-step explanation:
To determine price per lb, divide dollar amount by lbs.
- Company A sells 2 1/2lbs (2.5lbs) for $32.50
So, Company A's price / lb = ($32.50/2.5lbs) = $13.00/lb
- Company B sells 2 3/4lbs (2.75lbs) for $35.00
And, Company B's price / lb = ($35.00/2.75lbs) = $12.73/lb
Therefore, Company B is offering the lowest price/lb at $12.73/lb.
