Answer:

√35

Step-by-step explanation:

The right triangles are all similar, so the ratios of long leg to hypotenuse are the same for all:

z/7 = 5/z

z² = 35 . . . . multiply by 7z

z = √35

What is (-3 3/4) - (2 1/4)?

lisabon 2012 [21]

Answer: $-6$

Step-by-step explanation:

Rewrite the expression:

$-3\frac{3}{4}-2\frac{1}{4}$

Factor out the negative:

$-3\frac{3}{4}-2\frac{1}{4}$

$-(3\frac{3}{4} +2\frac{1}{4})$

Rewrite the sum:

$-(3\frac{3}{4} +2\frac{1}{4})$

$-((3+2)+(\frac{3}{4}+\frac{1}{4}))$

Calculate the sum:

$-((3+2)+(\frac{3}{4}+\frac{1}{4}))$

$-(5+1)$

Solve:

$-(5+1)$

$-6$

#2 Find the area.<br> 10ft

den301095 [7]

Answer:

It would be 78.539...

Step-by-step explanation:

So the equation for area is π r^2. We don't have the radius but we have the diameter. Since the radius is always 1/2 of the diameter, simply divide 10/2 to get this.

Now with the radius, it can simply be plugged into the equation for the answer:

π r^2,

π 5^2,

π 25

78.539...

Thanks for your answer

I just had a test on this lol perfect timing. Anyways the answer would be 3 times bigger bc the circumference of a circle with the radius of 3 is 6pi and the circumference of a circle with the radius of 1 is 2pi which makes the first circle 3 times bigger
