<span>A. 30 ft
The formula for the area of a rectangle is width x length = area. Knowing this formula, we can solve for the length by dividing the area by the width. 600 divided by 20 is 30.</span>
The area is 57 square feet.
Small rectangle is 4 x 3 which is 12.
Big rectangle is 7.5 x 6 which is 45.
Add both areas of the shapes and you get 57.
Answer:
Amount of fabric left = 1 ft
Step-by-step explanation:
Given:
Amount of fabric Marlene had = 7 ft
Amount of fabric Marlene used = 6 ft
Find:
Amount of fabric left
Computation:
Amount of fabric left = Amount of fabric Marlene had - Amount of fabric Marlene used
Amount of fabric left = 7 ft - 6 ft
Amount of fabric left = 1 ft
Answer:
3.7
Step-by-step explanation:
Inversely means we are taking the constant and dividing it.
So y varies inversely with x means "y=k/x".
k is a constant. We can find the constant if they give us a point on this curve.
The constant is a number that doesn't change no matter your input and output.
So they actually give us k=8.88 and y=2.4 so let's input this:
We need to solve this equation for x. You can do your favorite thing in cross-multiply. But how, Freckles? Well just slap a 1 underneath that 2.4. You can do that because 2.4/1 is still 2.4.
Cross-multiply:
Divide both sides by 2.4:

Step-by-step explanation:
Complete question;
In what time will Rs 10000 will yield a compound interest of Rs 2769 at 3% per annum
Using the compound interest formula;
A =P(1+r)^n
Given
P = Rs10000
A = 10000+2769
A = 12769
rate = 3% = 0.03
Substitute and get the time t
12769 = 10000(1+0.03)^n
12769/10000 = 1.03^n
1.2769 = 1.03^n
log 1.2769 = nlog1.03
n = log 1.2769/log 1.03
n = 0.1062/0.01283
n = 8.27
Hence the time is approximately after 8years
