They both want to buy the meal deal. Jessica has 34 of the money needed to buy the meal deal and Callista has half of the money needed to buy the meal deal. If the meal deal was $3 cheaper, then together they would have exactly enough money to buy two of the meal deals.
What is the original price of the meal deal? Show or explain how you got your answer.
The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4
How to write and solve equation?let
x = cost of the meal
Both = 2x - 3
Jessica = 3/4xCallista = 1/2x3/4x + 1/2x = 2x - 3
(3+2)x / 4 = 2x - 3

There are ten cards numbered from 1 to 10. Take out three cards from them.
i) the probability that the product of the numbers of the three cards is an odd number is
ii) the probability that the sum of the numbers of the three cards is an even number is
Answer:
Step-by-step explanation:
Part A
There are 5 odd numbers from 1 to 10. All three of them must be odd when drawn. I have to assume that there is no replacements.
Probability (odd) = (5 * 4 * 3) / (10 * 9 * 8) = 60 / 720
Probability (odd) = 0.083333
Part B
This is a little harder because 1 even number will turn everything even. So the way to handle this is to assume that there is (1 - probability(odd)) *720 that you have even
So the chances of an even result is 1 - odd/ total or
(1 - 1/12) * 720 = 660/720 = 0.917
Answer
Odd: 0.0833
Even: 0.917

Step-by-step explanation:
You plan to build a house that is 1 ½ times as long as it is wide. You want the land around the house to be 20 feet wider than the width of the house, and twice as long as the length of the house, as shown at the right.
The total area with land based on the information given is 3x² + 60x.
How to find the area?Let the width = x
Let the length = (1.5 × x) = 1.5x
Area = 1.5x × x = 1.5x²
The area along with land:
Width = x + 20
Length = 3 × x = 3x
The total area with land:
= Length × Width
= 3x(x + 20)
= 3x² + 60x.

The difference between two numbers is 31. Four times the smaller is equal to eight more than the larger. What are the numbers?
Answer:
13 and 44
Step-by-step explanation:
let x and y be the 2 numbers with y < x , then
x - y = 31 ( add y to both sides )
x = y + 31 ( subtract 31 from both sides )
x - 31 = y → (1)
4y = x + 8 → (2)
substitute y = x - 31 into (2)
4(x - 31) = x + 8
4x - 124 = x + 8 ( subtract x from both sides )
3x - 124 = 8 ( add 124 to both sides )
3x = 132 ( divide both sides by 3 )
x = 44
substitute x = 44 into (1)
44 - 31 = y , then
y = 13
the 2 numbers are 13 and 44

A. Obtuse
B. Acute
C. Right
D. None of these
Answer:
Acute Triangle.
Explanation:
The figure shows an equilateral triangle which has all the angles equal.
Acute Triangles are those who has angles less than 90°
Hence, an equilateral triangle is always an acute triangle.
Additional,
A right angle triangle has 90° angle.
An obtuse triangle has greater than 90° angle.

Answer:
(x + 5)^2 + (y + 8)^2 = 6^2
Step-by-step explanation:
A circle formula: (x - h)^2 + (y - k)^2 = r^2
We are given diameter. To find the radius divide diameter by 2.
d = 12
12/2 = r = 6
H and K are given to be (-5 , -8)
(x - (-5))^2 + (y - (-8))^2 = 6^2
(x + 5)^2 + (y + 8)^2 = 6^2

Use the Law of Detachment to draw a conclusion from the two given statements. If two angles are complementary, then the sum of their measures is 90°. E and F are complementary.
Using the law of detachment, the conclusion we can draw from the two given statements is: C. m∠E + m∠F = 90°.
What is the Law of Detachment?The law of detachment states that, if two statements are true, a third statement that is true can be derived also.
From the information given, we have:
First statement: If 2 angles are complementary, then their sum equals 90 degrees (If p, then q).
Second statement: Angles E and F are complementary (p).

solve log base 6 (x-6) - log base 6 (x + 4) = 2
Answer:
no solutions
Step-by-step explanation:
Since the two terms have the same base, we are able to use the rule for subtracting logarithms:
[tex]log_{b}(x) - log_{b}(y) = log_{b}(\frac{x}{y} )[/tex]
Therefore, the equation can be written as:
[tex]log_{6}(\frac{x-6}{x+4} )=2[/tex]
By using the definition of a logarithm we can say that:
[tex]\frac{x-6}{x+4} = 6^{2}\\\frac{x-6}{x+4} = 36\\x -6 = 36x+144\\35x = -150\\x =-\frac{30}{7}[/tex]
When plugging this solution in, you find that the term [tex]log_{6}(x-6)[/tex] has x-6 evaluate to a number less than 0. This is not included in the domain of log functions, so [tex]-\frac{30}{7}[/tex] is not a valid solution. This means that there are no solutions.

The distribution of head circumference for full term newborn female infants is approximately normal with a mean of 33.8 cm and a standard deviation of 1.2 cm.
Determine the approximate percentage of full term newborn female infants with a head circumference between 31 cm and 36 cm. Enter your answer using two decimal places.
Using the normal distribution, it is found that 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 33.8, \sigma = 1.2[/tex]
The proportion of full term newborn female infants with a head circumference between 31 cm and 36 cm is the p-value of Z when X = 36 subtracted by the p-value of Z when X = 31, hence:
X = 36:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{36 - 33.8}{1.2}[/tex]
Z = 1.83
Z = 1.83 has a p-value of 0.9664.
X = 31:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{31 - 33.8}{1.2}[/tex]
Z = -2.33
Z = -2.33 has a p-value of 0.0099.
0.9664 - 0.0099 = 0.9565.
0.9565 = 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.

Using a geometric sequence, it is found that the maximum height reached after the 5th bounce is of 43.48 feet.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, the ball is dropped from a height of 101.00 inches onto a hard flat floor, and after each bounce, the height is 19% less, that is, 81% of the previous height, hence the first term and the common ratio are given by:
[tex]a_1 = 101, q = 0.81[/tex]
Then, the height of the nth bounce is given by:
[tex]a_n = 101(0.81)^{n-1}[/tex]
And the height of the 5th bounce is:
[tex]a_5 = 101(0.81)^{5-1} = 43.48[/tex]

What is the surface area of a triangular prism?
The surface area of a triangular pyramid is the total area of all it's faces.
The properties of a triangular prism are;
It has a triangular base It is bounded y three lateral triangular faces meeting at one vertex. It has all its faces as trianglesHow to determine the surface area
Surface area = Base Area + 1÷2 (perimeter × base height)
But base area = 1÷2 (base side × height)
Base area = 1÷ 2 (8 × 14) = 0.5 × 112 = 56 in²
Perimeter = sum of all the sides = 14 + 8 + 6.9 = 28. 9 in
Base height = 6. 9in
Surface area = 56 + 1 ÷ 2 ( 28.9× 6. 9) = 56 + 0.5 × 199.41 = 56 + 99. 705 = 155. 705 in²
