Point O is on line segment NP. Given N P = 4x + 10, NO = 4x, and
OP = x + 5, determine the numerical length of NP.
Answers
Answer:
30
Step-by-step explanation:
Hope this will help:)
The numerical length of line segment NP will be 30 units.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a path that joins two places.
Point O is on line segment NP.
Given NP = 4x + 10, NO = 4x, and OP = x + 5.
We know that for a line segment.
PN = PO + ON
4x + 10 = 4x + x + 5
x = 5
Then the numerical length of line segment NP will be
NP = 4x + 10
NP = 4(5) + 10
NP = 20 + 10
NP = 30
Then the numerical length of line segment NP will be 30 units.

Lani’s father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied to the discounted price. What does Lani’s father pay for the meal? $_________
Answers
Explanation:
20$ x 15/100 = 3$ = discount price
20$ - 3$ = 17$ = discounted price
But 7% sales tax is added to the discounted price.
17 x 7/100 = 1.19$
17$ + 1.19$ = 18.19$ = price for the meal

Central Park in New York City is shaped like a rectangle. On a map of the park
in the coordinate plane, three of the vertices are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25). Distances on the map are in miles. What is the
perimeter of Central Park? Show your work,
Answers
Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres

In the answer space below, provide one of the two positive integers whose product is 196 and whose sum is a minimum.
Answers
Answer:
14
Step-by-step explanation:
The value of two positive integers are 14 and 14.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Product of two positive integers are 196.
Sum of two positive integers are minimum.
Now,
Let two positive integers are x and y.
Since, Product of two positive integers are 196.
So, we can formulate;
xy = 196 ... (i)
And, Sum of two positive integers are minimum.
So, we can formulate;
s = x + y
From equation (i);
y = 196/x
Substitute in above equation, we get;
s = x + y
s = x + 196/x
Differentiate with respect to x as;
d/dx (s) = d/dx(x + 196/x)
ds/dx = 1 - 196/x² ... (ii)
Substitute ds/dx = 0, we get;
ds/dx = 1 - 196/x² = 0
1 - 196/x² = 0
1 = 196/x²
x² = 196
x = ± 14
Differentiate equation (ii) again;
d²s/dx² = 0 - (-2 × 196)/x³
d²s/dx² = 392/x³
At point x = 14,
d²s/dx² = 392/8³ > 0
Hence, At x = 14, the value is minimum.
So, we get;
xy = 196
at x = 14
y = 196/14
y = 14
Hence, The value of two positive integers are 14 and 14.

You are choosing between two different cell phone plans. The first plan charges a rate of 22 cents per minute. The second plan charges a monthly fee of $34.95 plus 8 cents per minute. Let t be the number of minutes you talk and C1 and C2 be the costs (in dollars) of the first and second plans. Give an equation for each in terms of t, and then find the number of talk minutes that would produce the same cost for both plans (Round your answer to one decimal place). C1= C2= If you talk for minutes the two plans will have the same cost.
Answers
Answer:
249.64285714 minutes
Step-by-step explanation:
Let
The number of minutes you talk = t
C1 = Cost in dollars of the first plan
C2 = Cost in dollars of the second plan
First plan
The first plan charges a rate of 22 cents per minute
Converting cents to dollars
100 cents = 1 dollars
22 cents =
22/100 cents
=$ 0.22
C1 = $0.22 × t
C1 = 0.22t
Second Plan
The second plan charges a monthly fee of $34.95 plus 8 cents per minute.
Converting cents to dollars
100 cents = 1 dollars
8 cents =
8/100 cents
=$ 0.08
C2 = $34.95 + 0.08t
Find the number of talk minutes that would produce the same cost for both plans
We would Equate C1 to C2
C1 = C2
0.22t = $34.95 + 0.08t
Collect like terms
0.22t - 0.08t = $34.95
= 0.14t = $34.95
Divide both sides by 0.14
= t = $34.95/0.14
t = 249.64285714
Therefore, the number of talk minutes that would produce the same cost for both plans is 249.64285714 minutes.

A graph of the Soaring Cupcake’s cost per cupcake is shown below. The graph shows a relationship between the number of cupcakes purchased, n, and the total cost of the order, t. The Soaring Cupcake charges a $15 initial fee and then $3.00 for every cupcake purchased. What is the total cost for 15 cupcakes? What is the total cost for 10 cupcakes? How many cupcakes can you order for $30? Write a function rule in function notation for the situation using the variables t and n: A.) Does an input value of 4 make sense for this situation, why? B.) Does an input value of 5.2 make sense for this situation, why?
Answers
Answer:
1) $60
2) $45
3) 5 cupcakes ;; function for situation is 30(n)=3n+15
3A) No
3B) No
Step-by-step explanation:
the function is f(x)=3x+15 where x= cupcakes
To find total cost for 15 cupcakes, simply look at the graph or if you don't trust your eyeballing skills, you would calculate it by:
f(15)=3x+15 meaning plug 15 into the equation which equal $60
same for 10 cupcakes
f(10)=3(x)+15 equals $45
# of cupcake order for $30
using the graph we can see that for $30 we can purchase 5 cupcakes
the function for the situation is 30(n)=3n+15
A) No it would not make sense because after substituting 4 for the n, it does not equal to 30
B) Yes it would make sense because substituting 5.2 for n, it equal to $30.6 or $30
Tickets to the movies are $7 for adults and $4 for children. If 272 tickets
sold $1694, then how many of each type were sold?
Answers
Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
[tex]a + b = 272[/tex]
Now, make sure that only one of the unknown values remain on the left hand side. For example:
[tex]a = 272 - b[/tex]
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
[tex]7a + 4b = 1694[/tex]
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
[tex]7(272 - b) + 4b = 1694[/tex]
Then just solve the equation by finding the value of b.
[tex]7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\ = 70[/tex]
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
[tex]a = 272 - b \\ = 272 - 70 \\ a = 202[/tex]

Answer:
My answer to the question is 3.745kg.
Option B
The required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.
Given that,
Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms is to be determined.
A kilogram is the standard unit of measurement of weight.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
1 kilogram = 1000 gram
1 gram = 1 / 1000 kilogram
Multiply both side by 3,745
3,745 gram = 3,745 / 1000 kilogram
3,745 gram = 3.745 kilogram
Thus, the required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.
