Shari bought 2 1/2 yard of fabricfor $7.99 per yard. She used 3/4 of fabric to make decorative pillows. How much money could Shari have saved by only buying the amount of fabric that she used? Write your answer in dollars and round to the nearest tenth.

Answers

First, calculate how much Shari paid in total for 2.5 yards of fabric. Since each yard costs $7.99, you would multiply the number of yards Shari bought by the price per yard:
7.99×2.5=19.975, which rounds to $19.98

Then, calculate how much fabric Shari actually used:
(3/4)×2.5 yds= 1.875 yards

Next, calculate how much Shari would have paid if she only bought the amount of fabric that she used (1.875 yards):
7.99×1.875=14.98125, which rounds to $14.98

Lastly, to find the amount Shari could have saved, subtract $14.98 from the amount Shari actually paid, $19.98:
19.98-14.98=5. 
So, the final answer would be that Shari could have saved $5.

Find the length of the hypotenuse of the triangle.

Answers

a² + b² = c²
(1/3)² + (4/5)² = c²
1/9 + 16/25 = c²
0.11 (2dp) + 0.64 = c²
0.75 = c²
c = √0.75 = 0.87 (2dp) mm

A shelf is the shape of a triangle. Find the angles of the triangle if the measure of the angle are in the ratio x:x:4x.show work please

Answers

The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!

For every hour that Noah studies, his test score goes up 3 points. Explain which is the independent variable and which is the dependent variable. Write an equation modeling the relationship between hours studied h and the increase in Noah's test score s.

Answers

The independent variable is hours and the score or points is the dependent variable .equation is s=3h
The independent variable is the test hours that he studies; because they are not affected by any of the other variables. The dependent variable is the test score; because the amount of the test score depends on the variable of the studied hours. 

t=test score
h=hours studied
 
t+h3

Not sure about the equation though. Might wanna check that. Hope this helps!
