Answer:

4) 1400 $in^3$

5) 304 $\Pi$ or 954.56 $yd^3$

6) 315 $ft^2$

Step-by-step explanation:

$4)$

$V = \frac{lwh}{3} = \frac{20*20*10.5}{3} = \frac{4200}{3} = 1400$

$5)$

$A = \Pi(\frac{D}{2})^2 = \Pi(\frac{8}{2})^2 = \Pi*4^2 = 16\Pi$

$V = A * h = 16\Pi * 19 = 304\Pi = 304 * 3.14 = 954.56$

$6)$

$h^2 = 8^2 + 8^2 => h^2 = 64 + 64 = 128 => h =\sqrt{128}$

$A_1 = 2(\frac{8*\sqrt{128}}{2}) = 8*\sqrt{128} = 32 = 90.5$

$A_2 = 2(14 * 8) = 2*112 = 224$

$A = A_1 + A_2 = 91 + 224 = 315$

Lauren save $84 more than Fiona. 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving. How much did Lauren and

muminat

Answer:

Lauren's saving=$180

Fiona's saving=$96

Step-by-step explanation:

Let the saving's of fiona be x

Now given that the savings of lauren is $84 more than fiona which means the saving's of lauren is x+84

Given 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving

$\frac{1}{5}(lauren's saving)=\frac{3}{8}(fiona's saving)$

$\frac{1}{5}(x+84)=\frac{3}{8}(x)$

$8x+672=15x$

$7x=672\\x=96$

Therefore the saving's of fiona is $96 and the saving's of Lauren's is 96+84=$180

Hellen used a coupon she received in the mail at a local boutique that decreased her purchase of $85.20 by $12.78. Her sister us

Over [174]

Answer:

y = 12665 (100⁻¹) + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is = $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is = $54.23

So y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100 + b

y = 12665 (100⁻¹) + b

Where m = 12,665 and x = 100⁻¹
