Answer 1

Answer:

Each side is 15 ft

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

225 ft^2 = s^2

Take the square root of each side

sqrt ( 225 ft^2) = sqrt ( s^2)

15 ft = s

Each side is 15 ft

Answer 2

The square root of 225 is 15

Step-by-step explanation:

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary of $625 per week. How much did she earn last week if she sold $4,500 in electronics merchandise? Round your intermediate calculations and answer to the nearest cent

Answers

Danielle earned $951.25

Step-by-step explanation:

Multiply her commission by her sales and add her base rate

x=7.25%($4500)+625 or x=0.0725(4500)+625

distribute

x=326.25+625

What is the equation of the line y + 5 = -3(x - 6) in slope intercept form?
Y = MX + B

a.) y = -3x + 13

b.) y = -3x - 11

c.) y = -3x - 13

d.) y = -3x - 23

Answers

Answer:

Step-by-step explanation:

y+5=-3x+18

subtract 5 from both sides

y+5-5=-3x+18-5

y=-3x+13

The required equation of the line in the slope-intercept form is y = -3x + 13. Option A is correct.

Given that,
To transform the given point-slope form of the equation into slope-intercept form.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given the form of the equation of the line,
y + 5 = -3(x - 6)
Simplifying,
y = -3x + 18 - 5
y = -3x + 13

Thus, the required equation of the line in the slope-intercept form is y = -3x + 13. Option A is correct.

solve and graph the absolute value inequality: |2x + 4| > 8

Answers

Answer:

Step-by-step explanation:

To get rid of the absolute value bars you have to get two different equations which would be 2x+4>-8 AND 2x+4>8. Pay attention to the signs, if there is greater than or equal to then it would have a line underneath the sign, which neither of the equations should have since you haven't moved a negative. solve normally and you'll get -6 blank circle and 2 blank circle.

O {x|x ER, X2 4}
O {x|x ER, XS4}
{x|x ER, X2}
O {x|x ER, XS 2

Answers

The domain in set notation is {x | xER, -∝ < x < ∝}

How to determine the domain

From the question, we have the following parameters that can be used in our computation:

F(x) = (3x - 12) + 2

There is no restriction on the input values, x

So, the domain of F(x) = (3x - 12) + 2 is all real numbers, since there is no restriction on the input (x).

In set notation, we have

{x | xER, -∝ < x < ∝}

Answer:

The measure of the interior angle is 156°

The polygon has 15 sides

Step-by-step explanation:

Let us revise some facts in a polygon

The sum of the exterior angles of any polygon is 360°At each vertex of a polygon, the exterior and interior angles formed a pair of linear angles (The sum of their measures is 180°)A regular polygon has equal angles and equal sides

In our question

∵ The measure of an exterior angle of a regular polygon = 24°

∵ The sum of measures of the interior angle and exterior angle at

a vertex of a polygon is 180°

∴ The measure of the interior angle = 180° - 24°

∴ The measure of the interior angle = 156°

∵ The sum of the exterior angles of any polygon is 360°

∵ The polygon is regular (all angles are equal in measures)

∴ The measure of each exterior angle = 360° ÷ n, where n the

number of its angles or sides

∴ 24° = 360°/n

→ Multiply both sides by n

∴ 24n = 360

→ Divide both sides by 24

∴ n = 15

∴ The polygon has 15 sides

1. Astronauts traveling to the International Space Station have to be very careful about
weight (it takes about 9 lbs of rocket fuel to send 1 lb of stuff to the station). Each
astronaut can bring approximately 11 lbs of personal items (mementos and clothes)
with them into space. Each memento weighs about 0.1 lb, and each item of clothing
weighs about 0.5 lbs. If an astronaut wanted to bring 30 items with them, how many
mementos and pieces of clothing would they bring?

Answers

Answer:

10 mementos and 20 items of clothing

Step-by-step explanation:

Using the system of linear equations, the astronauts will bring 10 mementos and 20 clothings.

Let :

mementos = mClothing = c

m + c = 30 - - - - - - - - - (1)0.1m + 0.5c = 11 - - - - - (2)

From (1) :

m = 30 - c - - - - (3)

Put m = 30 - c in (2)

0.1(30 - c) + 0.5c = 11

3 - 0.1c + 0.5c = 11

Collect like terms :

0.4c = 11 - 3

0.4c = 8

c = 8/0.4

c = 20

From (3) :

m = 30 - c

m = 30 - 20

m = 10

Therefore, Astronaut will bring 10 mementos and 20 clothings.

Answer:

Displacement is 500m

Step-by-step explanation:

North=700m

East= 300m

South=300m

y=700-300=400m

x= 300m

We know that the displacement is found using the Pythagoras theorem

let the displacement be d

d^2= x^2+y^2

d^2= 400^2+300^2

d^2= 160000+90000

d^2=250000

What is a Line of Symmetry?

A line of symmetry is a fictitious line that divides a shape or figure into two equal halves, one of which is a mirror image of the other.

A line of symmetry running along the vertical axis will divide the supplied triangle into two equal halves (x-axis).

Equation of the Vertical axis is expressed as

x = -3.

Thus, the equation that describes the line of symmetry is: x = -3.

Elena has some bottles of water that each holds 17 fluid ounces. Write an equation that relates the number of bottles of water (b) to the total volume of water (w) in fluid ounces.

1) How much water is in 51 bottles?

2) How many bottles does it take to hold 51 fluid ounces of water?

Answers

Answer: The equation that relates b to w is 17b=w

1) How much water is in 51 bottles? : 867 fluid ounces

2) How many bottles does it take to hold 51 fluid ounces of water? : 3 bottles

Step-by-step explanation: If you want an explanation, here you go:

For the first question (how much water is in 51 bottles), you use the equation that I wrote, 17b=w. Substitute the b with the amount of bottles, 51, and just solve for the variable, w. You get (17*51=) 867 fluid ounces.

For the second question (how many bottles does it take to hold 51 fluid ounces of water), you simply divide. 51/17=?. ?=3 bottles.
