Helppp!

Answers

Answer:

[tex]5x+3x \leq 45[/tex] represents all possible combinations of x tulips and y carnations

Step-by-step explanation:

We are supposed to find inequality represents all possible combinations of x tulips and y carnations

Cost of 1 tulip = $5

Cost of x tulips = 5x

Cost of 1 carnation =$3

Cost of y carnations = 3y

We are given that she does not want to spend more than $45.

So, She can spend less than or equal to 45

So, required inequality :[tex]5x+3x \leq 45[/tex]

So, Option B is true

[tex]5x+3x \leq 45[/tex] represents all possible combinations of x tulips and y carnations

Answer:

it would be 5x + 3y <= 45

Answers

Answer:

Find the volume of the sphere.

Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

The radius is 1

Volume = [tex]\frac{4}{3} \pi[/tex] or 4.19

Step-by-step explanation:

Given

Radius, r = 1

Required

Find the volume of sphere

Volume of a sphere is calculated using the following formula

[tex]V = \frac{4}{3} \pi r^{3}[/tex]

Where V = Volume and r = radius

By Substitution,

[tex]V = \frac{4}{3} \pi * 1^{3}\\\\V = \frac{4}{3} \pi * 1\\\\V = \frac{4}{3} \pi[/tex]

Solving further to get the numerical value of volume;

We have to substitute 3.14 for π

[tex]V = \frac{4}{3} * 3.14V = 4.1866[/tex]

V = 4.19 to the nearest hundredth

Answer:

4.19

Rachael is placing a protective cover on a glass case. The case is a cube and the perimeter of one face of the cube is 56 inches. How many square inches of the protective covering does she need for the case?

Answers

Answer:

to cover this cube she needs at least 1,176 square inches of protective covering.

Step-by-step explanation:

The surface area of a cube is given by the following formula:

surface area cube = 6*l²

While the perimeter of each face of the cube is:

perimeter face = 4*l

Where l is the length of each side of the cube. Applying the data from the problem we have:

56 = 4*l

l = 56/4= 14 inches

surface area cube = 6*(14)²

surface area cube = 6*(196)

surface area cube = 1,176 square inches.

Therefore to cover this cube she needs at least 1,176 square inches of protective covering.

coordinates of the other point?
A (2, 2)
B (2, 3)
C (2, –3)
D (–2, –3)

Answers

Answer:

D (-2, -3)

Step-by-step explanation: The distance is 10 units, so you take -4 (x) and go over 2 spaces so your at x = -2, and 2 units are down, 8 more to go. Then for (y) you do 5-8 and get -3 so now y = -3 . Now you have moved 10 spaces because 2 + 8 = 10 spaces, and are left at D (-2, -3).

C
