Answer:

28 blue marbles

Step-by-step explanation:

since the ratio s 7/4, we have to make 49/x=7/4. 7 times 7 is 49, so 4 times 7 must be x. 4 times 7 is 28, so there are 28.

The height of a cylinder is 8 centimeters. The circumference of the base of the cylinder is 20π centimeters. Which measurement i

trapecia [35]

Answer: $2514.28\ cm^3$

Step-by-step explanation:

Given

The height of the cylinder is $h=8\ cm$

Circumference of the base is $20\pi \ cm$

suppose 'r' is the radius of the cylinder

$\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm$

The volume of a cylinder is $V=\pi r^2h$

$\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3$

Jason rolls the die 14 times. What is the experimental probability that he will roll a 2

Vaselesa [24]

There’s 14 rolls. The probability he lands on a 2 would be 2/14. Once you simplify it it would give you a probability of 1/7

make up an equation in the form of an y=kx +b, the graph which passes through the following points: (5,5) and (-10,-19)

Oksana_A [137]

Answer:

y = 8/5x - 3

Step-by-step explanation:

First, find the slope using rise over run (y2 - y1) / (x2 - x1)

(y2 - y1) / (x2 - x1)

(-19 - 5) / (-10 - 5)

-24 / -15

= 8/5

Plug in the slope and a given point into y = mx + b, and solve for b

y = mx + b

5 = 8/5(5) + b

5 = 8 + b

-3 = b

Plug in the slope and b into y = mx + b

y = 8/5x - 3

So, the equation is y = 8/5x - 3
