Answer:

see explanation

Step-by-step explanation:

The factors of 36 which are perfect squares are 9 and 4, thus

$\sqrt{9}$ × $\sqrt{4}$ = 3 × 2 = 6

$\sqrt{36}$ = 6

This confirms the radical rule

$\sqrt{ab}$ = $\sqrt{a}$ × $\sqrt{b}$

That is

$\sqrt{36}$ = $\sqrt{9(4)}$ = $\sqrt{9}$ × $\sqrt{4}$ = 3 × 2 = 6

Andrew [12]

Since we are dealing with VOLUME, when you increase an amount, we CUBE the difference. 2^3 = 8
The sphere that has 2 times the radius has 8 times the volume.

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = m
Short answer = s

Equations:

m + s = 38
2m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)
3s - 2s = 93 - 76
s = 17

Find the value of m:

m = 38 - 17 = 21

Answer:

BZ = 64/23 = 2 18/23

Step-by-step explanation:

The angle bisectors divide the triangle into proportional parts, so we have ...

CB/CY = AB/AY

CB = CY(AB/AY) = 4(8/6) = 16/3 . . . . multiply by CY and evaluate

and ...

BZ/CB = AZ/AC

BZ = AZ(CB/AC) . . . . multiply by CB

But we have ...

AZ = 8 -BZ, so this becomes ...

BZ = (8 -BZ)(16/3)/(10)

BZ(1 +8/15) = 64/15 . . . . add the BZ term on the right to both sides

BZ = (64/15)(15/23) = 64/23 . . . . divide by the coefficient of BZ

BZ = 64/23 = 2 18/23
