hope this helped. have a good one!
Answer:
The change in the area of the rectangle is 0 square feet
Step-by-step explanation:
To solve this problem we have to calculate the area of the two rectangles that give us
first we have to know the formula to calculate the area of a rectangle
a = area
l = length = 12ft
w = width = 5ft
a = l * w
we replace the known walues
a = 12ft * 5ft
a = 60ft²
we do the same with the other rectangle, but first we have to calculate its sides
w = 5ft - (5ft * 20/100)
w = 5ft - 1ft
w = 4ft
l = 12ft + (12ft * 25/100)
l = 12ft + 3ft
l = 15ft
a2 = 15ft * 4ft
a2 = 60ft²
to calculate the change in the area we subtract (a - a2)
a - a2 =
60ft² - 60ft² = 0ft²
Answer:
1. x = 7/2 + 5y/2
2. x = 3/4 - 5y/8
3. x = 1/8 = 5y/8
Step-by-step explanation:
Thats all i can do. Its too confusing
Hi , 7/16 times 4/3 times 1/2 equals to 28/96 because 7times4 times 1 equals to 28 and 16 times 3 times 2 equals to (28/96).The answer is also equivalent to 7/24.
Answer:
Part a) The expression is ![3.2445x](https://tex.z-dn.net/?f=3.2445x)
Part b) Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
Step-by-step explanation:
<u><em>The complete question is</em></u>
A spice store charged 2.75 for 25 grams of paprika. It also charges 5% of the purchase price for shipping any order.
Part a) Write and simplify an expression to determine the cost of buying and shipping x ounces of paprika. Use 1 ounce = 28 grams
Part b) Can a customer buy 2.5 ounces of paprika and have it shipped for less than 8.00? Explain
step 1
Convert grams to ounces
Remember that
![1\ oz=28\ g](https://tex.z-dn.net/?f=1%5C%20oz%3D28%5C%20g)
To convert grams to ounces divide by 28
![25\ g=25/28= 0.89\ oz](https://tex.z-dn.net/?f=25%5C%20g%3D25%2F28%3D%200.89%5C%20oz)
The unit price is
![2.75/0.89=3.09\frac{\$}{oz}](https://tex.z-dn.net/?f=2.75%2F0.89%3D3.09%5Cfrac%7B%5C%24%7D%7Boz%7D)
Let
x ----> the number of ounces of paprika
y ----> the cost of buying and shipping x ounces of paprika
5%=5/100=0.05
![y=3.09x+(3.09x)0.05\\y=3.09x[1+0.05]\\y=3.2445x](https://tex.z-dn.net/?f=y%3D3.09x%2B%283.09x%290.05%5C%5Cy%3D3.09x%5B1%2B0.05%5D%5C%5Cy%3D3.2445x)
Part b) For x=2.5 oz
substitute in the equation
![y=3.2445(2.5)=\$8.11](https://tex.z-dn.net/?f=y%3D3.2445%282.5%29%3D%5C%248.11)
![\$8.11 > \$8.00](https://tex.z-dn.net/?f=%5C%248.11%20%3E%20%5C%248.00)
therefore
Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
