how do you find the surface area of a net of a box with the length of 20 the width of 10 and the highth of 12

Answers

Answer 1

Answer:

Total Surface Area = 2(LW+WH+LH)

Step-by-step explanation:

Surface Area of;

face 1 = LW

= 20 × 10

=200

face 2 = WH

= 10×12

= 120

face 3 = LH

= 20×12

=240

TSA = 2(200+120+240)

=560×2

=1120

Answers

Solve for w by simplifying both sides of the equation, then isolating the variable.

Exact Form: w = 7 2 w = 7 2

Decimal Form: w = 3.5 w = 3.5

Mixed Number Form: w = 3

final answer: choice B
Answer:

b. 3.5

Step-by-step explanation:

The choices are:  

a. 3

b. 3.5

c. 4

d. 4.5

The equation is 5 = w + [tex]1\frac{1}{2}[/tex]

5 - [tex]1\frac{1}{2}[/tex] = [tex]3\frac{1}{2}[/tex]

w = [tex]3\frac{1}{2}[/tex]

[tex]3\frac{1}{2}[/tex] converted into a decimal equals 3.5

So the correct answer is b. 3.5

A company that makes robotic vacuums claims their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. What are the appropriate hypotheses?

H0: μ = 2 versus Ha: μ < 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ > 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model
H0: μ ≠ 2 versus Ha: μ = 2, where μ = the true mean run time for all vacuums of this model

Answers

Answer:

The answer is C. H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model

[tex]5\sqrt{3}[/tex]

Step-by-step explanation:

A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:

The side opposite the 30* angle = a

The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]

The side opposite the 90* angle = 2a

(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")

They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:

Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.

Once we know what "a" is, we can fill in the rest:

30* = 5

60* = [tex]5\sqrt{3}[/tex]

90* = 10

Find the measure of the missing angle.

Answer: a= ______

(NO FILES) IF YOU ANSWER YOU WILL BE MARKED BRAINLIEST :)

Answers

Answer:

a= 32

Step-by-step explanation:

Since "a" is a part of a supplementary angle (An angle that adds up to 180º)

What you would need to do is add 58º and 90º (90º because the right angle = 90)

so 58+90 = 148

Then you would subtract 148 from the total of the angle (Which is 180)

so 180 - 148 = 32, And that shows that a = 32

Drag the green point on the tape diagram to model a discount of 27%.

If the discount is 27%, then what percent of the original price do you pay?

Answers

Answer:

73%

Step-by-step explanation:

Let us have the original price as $100

A discount of 27% will be;

27/100 * 100 = $27

so, the value to be paid will be $100 - $27 = $73

Now, what percentage of $100 is the $73 that was paid

that would be;

73/100 * 100% = 73%

Maya owns a house valued at $432,600. She still owes $233,458 on her mortgage. How much equity does she have in the house? (3 points)

Answers

Answer:

$199,142

Step-by-step explanation:

Given that

The value of the house i.e. assets is $432,600

The mortgage i.e. liability is $233,458

We need to find out the equity

As we know that

The accounting equation is

Total assets = Total liabilities + total equity

$432,600 = $233,458 + total equity

So, the total equity is

= $432,600 - $233,458

= $199,142

Answer:

No, she is not correct. She has only $30,000 in home equity. Equity is the value of ownership in an asset minus any debts owed on it. $315,000 minus $285,000 is $30,000.

Monique's swimming pool filter needs repair. She calls two companies for prices. The
Pool Boyz charge $70 for a service call and $40/h for labour. Kemikal Balance charge
$50 for a service call and $45/h for labour.
a) Write a linear equation for each company.
b) Find the solution to this linear system

Answers

A) y = 70 + 40x, y = 50 + 45x

the first number is the initial service call charge, and the second number/slope is the rate per hour of the company, where x is the number of hours worked

B) x = 4

Since both equations are solved for y, you can set them equal to each other to get
70 + 40x = 50 + 45x

Solve for x to get x = 4.

Complete the square to find the vertex of this parabola. x2-16y-4x-12=0

Answers

Answer:

Step-by-step explanation:

x^2-16y-4x-12=0

Transpose and separate x and y

16y = x^2-4x-12

16y = (x^2-4x+4) -16

16y = (x-2)^2 -16

y = (1/16)(x-2)^2 -1

This means that the vertex is at

(x-2)=0 or x=2

y = -1

=> vertex (2,-1)
