10 packs of markers

Step-by-step explanation:

3 x 25 = 75 markers she will need for her whole class

Answer:

Simple

Rise/Run

for one week they run 10 miles

2 weeks 20 miles

3 weeks 30 miles

4 weeks 40 miles

the rate of change would be 10/1 (Why? Because you rise +10 each time per week.)

divide that it would be 10 (:

The radius of a right circular cylinder is increasing at the rate of 3 ft/sec, while the height is decreasing at the rate of 6 f
goblinko [34]

Answer:

\frac{dV}{dt}=-450\pi ft^3/sec

Step-by-step explanation:

Let's assume

radius of cylinder as 'r'

height of cylinder as 'h'

so, we have

\frac{dr}{dt} =3ft/sec

\frac{dh}{dt} =-6ft/sec

r=15ft

h=10ft

now, we can use volume of cylinder formula

V=\pi r^2h

we can find derivative with respect to t

\frac{dV}{dt}=2\pi r h\times\frac{dr}{dt} +\pi r^2\times \frac{dh}{dt}

now, we can plug values

\frac{dV}{dt}=2\pi (15)(10)\times3 +\pi (15)^2\times -6

now, we can simplify it

\frac{dV}{dt}=-450\pi ft^3/sec

A baker used 2/11 cup of flour to make 4/16 of a recipe. How much flour
soldi70 [24.7K]

Answer:

8/11 cup of flour

Step-by-step explanation:

2/11 cup of flour = 4/16 of the recipe

=> 2/11 cup of flour = 1/4 of the recipe

=> 4 x 2/11 cup of flour = 1/4 x 4 of the recipe

=> 8/11 cup of flour = full recipe

Therefore, it would require 8/11 cups of flour to make this recipe.

Hoped this helped.
