Volume is a three-dimensional scalar quantity. The correct option is C.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a slant cylinder is given by the formula,

Volume = π × (Radius of the cylinder)²× Slant height of cylinder

Given the radius of the cylinder is 3 units, while the slant height of the cylinder is 5 units, therefore, the volume can be written as,

Volume = π × (3 units)²× 5 units = 45π units³

Hence, the correct option is C.

Ken wants to buy some coffee mugs, m , that cost $5 each and some ground coffee, C, that costs $8 a pound. He has $25.

ValentinkaMS [17]

The inequality representation of the scenario is :

5m + 8c ≤ 25
m = 1 and c = 1

Number of mugs = m
Cost per mug = $5
Number of ground coffee = c
Cost per ground coffee = $8
Total amount to spend = $25

(Number of mug × cost per mug) + (Number of ground coffee × cost of ground coffee) ≤total amount to spend

Representing as an inequality : 5m + 8c ≤ 25

Combination of m and c that makes the inequality true :

Using trial by error :
m = 1 and c = 1
5(1) + 8(1) ≤ 25 ; 13 ≤ 25

Hence, m = 1 and c =1 are valid values for the expression.

pickupchik [31]

Answer:

E(3.75,-2.5)

G(-0.75,-3)

Step-by-step explanation:

Point E is the midpoint of the segment AB, then it has coordinates

$\left(\dfrac{-3+6}{2},\dfrac{-1+(-3)}{2}\right)=\left(\dfrac{3}{2},-2\right).$

Point F is the midpoint of the segment EB, then it has coordinates

$\left(\dfrac{\frac{3}{2}+6}{2},\dfrac{-2+(-3)}{2}\right)=\left(\dfrac{15}{4},-\dfrac{5}{2}\right)=(3.75,-2.5).$

Let S be the midpoint of segment CB, then it has coordinates

$\left(\dfrac{-3+6}{2},\dfrac{-3+(-3)}{2}\right)=\left(\dfrac{3}{2},-3\right).$

Point G is the midpoint of segment CS, then its coordinates are

$\left(\dfrac{\frac{3}{2}+(-3)}{2},\dfrac{-3+(-3)}{2}\right)=\left(-\dfrac{3}{4},-3\right)=(-0.75,-3).$

A school has a virus going around, and 8/25 of the students are absent due to the virus. An additional 20 students are out due t

Stells [14]

Answer:

268 students are absent

Step-by-step explanation:

First, multiply 775 by (8/25) to get the number of students out from the virus (probably weren't wearing masks or 6 ft apart from each other). This gives you 248 students. You also know that an additional 20 students are out due to other reasons. Add 248 and 20 and you get a total of 268 absent students.

Part A: If (7 to the power of 2)x = 1, what is the value of x?

andre [41]

(7^2)x = 1
49x = 1
x = 1/49

Part B
7^0 = 1

so we have
1x = 1

x = 1
