kobusy [5.1K]

Answer:

Frank

Step-by-step explanation:

So If Dave ate ¼ more than Frank, you would need to divide the denominator by the amount of pizzas, so if 12÷4 is 3 he ate three more pizzas than Frank. If we do the same for Frank, ⅕ or 15÷5=3

So the correct answer would be Frank because 12 is less than 15

My apologies if this wasnt explained very well

What expression is equivalent to

kaheart [24]

Answer:

Option (2)

Step-by-step explanation:

Given expression is $\sqrt[3]{64a^6b^7c^9}$

By simplifying this expression,

$\sqrt[3]{64a^6b^7c^9}=\sqrt[3]{(4)^3(a^2)^3(b^2)^3(b)(c^3)^3}$

$=(4a^2b^2c^3)\sqrt[3]{b}$

Option (1)

$2abc^2\sqrt[3]{4a^2b^3c}$ = $2ab^2c^2\sqrt[3]{a^2c}$

Option (2)

$4a^2b^2c^3(\sqrt[3]{b})$ [Fully simplified form]

Option (3)

$8a^3b^3c^4(\sqrt[3]{bc} )$ [Fully simplified form]

Option (4)

$8a^2b^2c^3(\sqrt[3]{b})$

Expression given in Option (2) is equivalent to the given expression.

Option (2) will be the answer.

Hey, I would appreciate it if you can help me with these problems, been stuck on it for a few days

Makovka662 [10]

Answer:

Explained below.

Step-by-step explanation:

The formula for average rate of change is:

$\frac{f(b) - f(a)}{b - a}$

1. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(2) - f(1)}{2 - 1}$ = $\frac{100 - 40}{2 - 1}$ = $\frac{70}{1}$ = 70

2. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(4) - f(2)}{4 - 2}$ = $\frac{180 -110}{4 - 2}$ = $\frac{70}{2}$ = 35

3. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(8) - f(6)}{8 - 6}$ = $\frac{350 -230}{8 - 6}$ = $\frac{120}{2}$ = 60

4. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(10) - f(8)}{10 - 8}$ = $\frac{390 -350}{10 - 8}$ = $\frac{40}{2}$ = 20

5. Their average speed was the greatest during the first to second hour.

6. Their average speed was the least during the eight to tenth hours.

7. $\frac{f(b) - f(a)}{b - a}$ = $\frac{f(10) - f(1)}{10 - 1}$ = $\frac{390 -40}{10 - 1}$ = $\frac{350}{9}$ = 38.89 or 38.9

Hope that helps!
