Answer:

0.25

Step-by-step explanation:

Average means $\frac{total \: number}{number \: \: of \: \: individuals}$

According to the formula, each student in Mr. Goldwasser's class read

$\frac{66}{24} = 2.75$

books on average, and each student in Mr. Welch's class read

$\frac{65}{26} = 2.5$

books on average.

Therefore, the answer will be

$2.75 - 2.5 = 0.25$

The ratio of width to length of a rectangle is 7:10.The width of the rectangle is 91 cm.

kvasek [131]

Answer:

Length= 130 cm

For, Width= 91 cm

Step-by-step explanation:

Ratio of the width to the length of the rectangle = 7:10

Width of the rectangle= 91 cm

$\frac{Width}{Length} =\frac{7}{10}$

As, Width = 91 cm

$\frac{91}{Length} =\frac{7}{10}$

On, Cross multiplication the fraction:

$91*10=7*Length$

$7*Length=910$

Dividing by '7' both the sides:

$Length=\frac{910}{7}\\\\ Length=130cm$

Find d<br><br> a * a * a = 216<br> a * b * c = 96<br> b * c = 52<br> a + b + c = d

Slav-nsk [51]

$a\cdot a\cdot a=216\\\\a^3=216\to a=\sqrt[3]{216}\\\\\boxed{a=6}\\\\\text{Substitute}\ b\cdot c=52\ \text{to the second expression}\ a\cdot b\cdot c=96:\\\\abc96\ \wedge\ bc=52\to a(52)=96\qquad\text{divide both sides by 52}\\\\a=\dfrac{96}{52}\to a=\dfrac{24}{13}\neq6$

a = 6 and a = 24/13 FALSE!!!
