Hello!

You solve this algebraically.

6(t - 2) = 2(9 - 2t)

Distribute the 6

6t - 12 = 2(9 - 2t)

Distribute the 2

6t - 12 = 18 - 4t

Add 4t to both sides

10t - 12 = 18

Add 12 to both sides

10t = 30

Divide both sides by 10

t = 3

The answer is 3

Hope this helps!

5/8 - 3/10 <br> A. 13/40 <br> B. 1/20 <br> C. 1/4<br> D. 1/5

5/8 - 3/10

Find the common denominator:

Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

5/8 = 5*5 / 8*5 = 25/40

3/10 = 3*4 / 10 *4 = 12/40

Now you have 25/40 - 12/40

25 -12 = 13

Answer = 13/40

The answer is A.

Answer:

C. 176.6 Square feet (I think)

Step-by-step explanation:

I tried many different ways and got three of the answers above but I think this is the right one.

The equation to find area of a circular cone base: $A= \pi r^2$

We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: $r = \frac{d}{2}$
Plug in numbers: $r=\frac{15}{2}$ ≈ $7.5$
Use the Area formula now that you have radius: $A=\pi 7.5^2$
Solve and get = $a = 176.71458676$
Looking at the options the closest one to our answer (off by one-tenth) is C.
