Answer: $1.15
Step-by-step explanation:
The question is How much did each roll of crepe paper cost?
Let the cost of crepe paper be x
Let the cost of balloons be y.
Six rolls of crepe paper and 20 balloons cost $11.90. This will be:
6x + 20y = 11.90 ......... i
2 more rolls of crepe paper and 15 more balloons for $6.05. This will be:
2x + 15y = 6.05 ......... ii
6x + 20y = 11.90 ......... i
2x + 15y = 6.05 ......... ii
Multiply equation i by 15
Multiply equation ii by 20
90x + 300y = 178.50 ........ iii
40x + 300y = 121 ........ iv
Subtract iv from iii
50x = 57.50
x = 57.50/50
x = 1.15
Therefore, a crepe paper cost $1.15

Can someone help me? And no, I don’t just want the answer. I literally need to know how to do it pls
Answer:
36
Step-by-step explanation:
The angle b is a right angle which is divided into 2. So, each angle would measure 45 degree. (90 / 2 = 45)
tan 45 = 1
\AD\ = 100 - 64 = 36
to find x , remember SOCAHTOA
tan would be used because we have the vale of the opposite angle and we want to find the value of the adjacent angle
Tan 45 = opposite / adjacent
1 = 36/x
x = 36

If the bathtub holds a total of 46.2 gallons, how many minutes would it take to fill the entire tub? Write an equation in one variable to help you
solve the problem. The variable represents the unknown time in minutes.

Answer:
It will take 2.8 minutes
Step-by-step explanation:
Given
[tex]x \to Minutes[/tex]
[tex]y \to Gallons[/tex]
See attachment for complete question
Required
Time to fill the tube with 46.2 gallons
The attached table is a represents a direct proportional relationship between x and y.
This relationship is:
[tex]y = kx[/tex]
Where k is the constant of proportionality.
When (x,y) = (1,16.5), we have:
[tex]16.5 = k*1[/tex]
[tex]16.5 = k[/tex]
[tex]k=16.5[/tex]
So, we have:
[tex]y = kx[/tex]
[tex]y = 16.5x[/tex]
To calculate the required time to fill 46.2 gallons, we make x the subject
[tex]x = \frac{y}{16.5}[/tex]
Where
[tex]y =46.2[/tex]
[tex]x = \frac{46.2}{16.5}[/tex]
[tex]x = 2.8[/tex]

David has a gift that he needs to wrap. He is trying to decide if he has enough Avengers wrapping paper or if he will have to use the plain blue
ones he has. The gift is 18 inches by 2 feet by 9 inches, rectangular shape. If he has a piece of Avengers wrapping paper that is 3.5 feet by 3
feet, is it enough to cover the present?
Answer:
no, it isn't enough to cover the present
Step-by-step explanation:
first, find the volume of the gift in feet
18*9=162 inches
162/12= 13.5 feet
13.5*2= 27 feet
then, the wrapping paper
3.5*3= 10.5 feet
compare them
27>10.5 meaning there isn't enough wrapping paper

18 is 4.5 times a number.
The value of x is equal to 4, that is 4.5 times 18 is 4
Given that the expression:
18 is equal to 4.5 times a number.
Assume that the number be x.
To find the number that is 4.5 times 18, we can set up the following equation:
4.5 × x = 18
Now, to find the value of x, divide both sides of the equation by 4.5:
4.5 × x / 4.5 = 18 / 4.5
x = 18 / 4.5
x = 4
So, the number that is 4.5 times 18 is 4.

Help find the missing side show your work and get brainly
Answer:
[tex]\sqrt{32}[/tex]
Step-by-step explanation:
Pythagorean - [tex]a^2+b^2=c^2[/tex]
where a and b = legs and c = hypotenuse
For the following problem we are given the hypotenuse ( [tex]\sqrt{84}[/tex] ) and a leg ( [tex]\sqrt{52}[/tex] ) and we need to find the missing side length ( which also happens to be a leg.)
That being said we can find the missing leg by plugging in what we are given into [tex]a^2+b^2=c^2[/tex] ( let a = missing side length )
[tex]a^2+\sqrt{52}^2=\sqrt{84} ^2\\\sqrt{52} ^2=52\\\sqrt{84}^2 =84\\a^2+52=84[/tex]
* subtract 52 from each side
84 - 52 = 32
52 - 52 cancels out
we now have a² = 32
step 2 take the square root of each side
[tex]\sqrt{a^2} =a\\\sqrt{32} =\sqrt{32}[/tex]
Assuming that we are supposed to leave the answer in radical form the answer would be sqrt 32
Answer:
7 in.
Step-by-step explanation:
Let x = the length of the missing side
[tex]x^{2} + \sqrt{32} ^{2} = \sqrt{81} ^{2}[/tex]
[tex]x^{2} +32 = 81[/tex]
[tex]x^{2} = 49\\[/tex]
x = 7 in.
