Answer:

The surface area is 174 cm^2

Step-by-step explanation:

Since we have the area of each of the faces, to get the total area, we will need to add up the areas of all these faces

Thus, we have that;

A = 45 + 27 + 45 + 15 + 15 + 27

A = 174 cm^2

Answer: What is the slope of this line? It's the 'm' term in y=mx+b. In this example, m=1. Therefore the slope of the line is 1, or said another way, the line goes "up" one unit every time it goes "over" one unit.

What is the y-intercept of the line? That's the 'b' term, so it's also 1. That means that when x is 0, y=1. Go ahead and plug x=0 into that equation to verify for yourself.

Step-by-step explanation:

Answer: 7

Equation: y= -1/2x + 7

Step-by-step explanation:

A slope of -1/2 means every x-value you go up by, the y-value goes down by 1/2.

To find an y-intercept you have to go back 4 x-values. So then you need to go up four 1/2 y-values. (simply 2 y-values).

Answer:

The discount was [tex]47\frac{6}{7}[/tex]%

Step-by-step explanation:

In order to find out the discount will have to do the following.

First find out what part of the origin price was taken of, so we create a fraction with the denominator being the original price and the numerator being the difference between the original price and the discount price. So we do.....

[tex]\frac{28.00-14.60}{28.00} = \frac{2800 - 1460}{2800} = \frac{1340}{2800} = \frac{67}{140}[/tex]

Now we have to find a fraction with the same value but with the denominator being a 100, so we do.....

[tex]\frac{67 / 1.4}{140/1.4}= \frac{47\frac{6}{7} }{100}[/tex]

From this we know that the the discount in percentages will be equal to [tex]47\frac{6}{7}[/tex]%

Answer:

52.1428571429

Step-by-step explanation:

14.60 × 100 = 1460

1460 ÷ 28 = 52.1428571429

Answer:

The most efficient way to breathe is by bringing the air down toward the belly. As the diaphragm contracts, the belly expands to fill the lungs with air. “Belly breathing” is efficient because it pulls the lungs downward, creating negative pressure inside the chest

Answer:

it's C

Step-by-step explanation:

Recall that linear (straight) equations are given in the form y = mx + b.  Looking at your options, we can see there is only one equation in this form, which is letter c, y = 12x + 17.  Therefore your answer is c.

Answer:

Hiya!! Love ur pfp and the answer is 6

Step-by-step explanation:

Something called math... I think lol

Answer:

6

Step-by-step explanation:

If you add 2+2, you get 4. If you add 4+2, you get 6. Multiplying 2x3 is basically doing 2+2+2, or 3+3.

Answer:

Step one add 4 to both sides

step two divide both sides by 17

step 3 is the answer and that is 62/17

Step-by-step explanation:

Hope this helps!!!

Answer:

x= 62/17

Step-by-step explanation:

17x - 4+4 = 58 + 4

17x= 62

17x/17 = 62/17

x = 62/17

Answer:

  x = 3

Step-by-step explanation:

The triangle is equilateral, so each side is equal to the others:

  5x = 3x +6

  2x = 6 . . . . . . . subtract 3x

  x = 3 . . . . . . . . divide by 2

Answer:

-30v + 5w + 5

Step-by-step explanation:

-5(6v - w - 1) =

Multiply -5 by each term inside the parentheses.

= -5 * 6v - (-5) * w - (-5) * (-1)

= -30v + 5w + 5

Answer:

The answer is D, 70

Answer:

2 seconds

Step-by-step explanation:

Given that:

h = -16t² + 28t + 8

Using quadratic formula:

[tex]\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

where;

a = -16

b = +28

c = +8

[tex]= \dfrac{-(28) \pm \sqrt{(28)^2 - 4(-16)(8)}}{2(-16)}[/tex]

[tex]= \dfrac{-(28) \pm \sqrt{784+512}} {-32}[/tex]

[tex]= \dfrac{-(28) + \sqrt{784+512}} {-32} \ \ OR \ \ = \dfrac{-(28) - \sqrt{784+512}} {-32}[/tex]

[tex]=- \dfrac{1}{4} \ \ OR \ \ 2[/tex]

Since we are considering the positive value; Then it will take the snowboarder 2 seconds before it hits the ground.

Answer:

The correct answer is A

Step-by-step explanation:

20% x 12 = 2.4

2.4 + 12 = 14.4

Answer:

the  next year population is 122,689

Step-by-step explanation:

The computation of the next year population is as follows:

= This year population × increase percentage

= 119,000 × (1 + 0.031)

= 119,000 × 1.031

= 122,689

Hence, the  next year population is 122,689

The above formula is applied so that the correct value of the population could come

Answer:

VX = 24

Step-by-step explanation:

Given :

VJ = 12 units

To find :

VX = ?

Solution:

Since, diagonal of a parallelogram bisect each other.

By this property,

m(VX) = 2[(VJ)]

m(VX) = 2(12)

          = 24 units

Therefore, measure of the diagonal (VX) of the given parallelogram is 24 units.

Answer: The value of the given expression = 101

Step-by-step explanation:

Given:  p=4,q=-3,and r=2

To find the value of expression [tex]p^3+q^3-r^3-3pqr[/tex].

Substitute all values p=4,q=-3,and r=2 in the expression, we get

[tex]4^3+(-3)^3-(2)^3-3(4)(-3)(2)\\\\=64-27-8+72\\\\=101[/tex]

Hence, the value of the given expression = 101
