Volume of the box would be width x length x height

If the box of an area already covers four feet (width times length) we just need to multiply by the height:

4*3 =12 cubic feet

Step-by-step explanation:

B

Answer:

b) $4.60

Step-by-step explanation:

a)

2 panels at $923.40 each = $1846.80

Total with installation: $1944.80

Installation $1944.80-$1846.80 = $98

b)

2 panels at $940.50 each = $1881.00

Total with installation: $1983.60

Installation $1983.60-$1881.00 = $102.60

Substract a from b

102.60-98 = 4.60

Paul went to a solar panel store and paid $923.40 per solar panel for two solar panels and a flat rate fee for installation for a total of $1944.80. Brad went to another solar panel store and paid $940.50 per solar panel for two solar panels plus a per solar panel installation fee for a total of $1983.60. What is the difference in the amounts they paid in installation charges? A. $5.60 B. $4.60 C. $3.60 D. $6.60

Answer:

151

Step-by-step explanation:

Volume of a cone can be found using the equation below

V=π(r^2)(h/3)

divide diameter by two to find the radius: 8/2=4

Plug the values into the equation: V=π(4^2)(9/3)

Simplify

V=π(4^2)(9/3)

V=π(16)(3)

V=150.79

Rounds up to 151

Answer:

23.9% = 47400

divide both sides by 23.9 to find 1%

1% = 1983.26359

Answer:

yes you can simplify it because both the denominators have common denominator of 15.

Answer:

Yes

Step-by-step explanation:

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Step-by-step explanation:

the triangle is a right triangle with base as 8 and height as 6 so solve area like any other triangle

8*6=48

48/2=24

Step-by-step explanation:

the process of finding out the variable value that makes the equation true is called 'solving' the equation. An equation is a statement that two quantities are equivalent. For exp/example:. x + 1 = 4 mean that when we add 1 to the unknown value, 'x', the answer is equal to 4 .

Answer:

A

Step-by-step explanation:

4(3)+12=24, which is less than 28, so the inequality would be true

Answer:

The answer is A)3

Step-by-step explanation:

4 multiplied by 3 is 12, 12+12 is 24, less than 28

2 multiplied by 6 is 24+12 is 36, greater than 28

4 multiplied by 7 is 28, already over 28

4 multiplied by 10 is 40 is already way over 28

Hope this helped!!!

Answer:

The length of the equal sides is 15 centimeters.

Step-by-step explanation:

Since, base and height of the triangle are perpendicular to each other. In an isosceles triangle, the value of each equal length ([tex]l[/tex]), measured in centimeters, can be determined by the following Pythagorean identity:

[tex]l = \sqrt{\frac{b^{2}}{4}+h^{2}}[/tex] (1)

Where:

[tex]b[/tex] - Base of the triangle, measured in centimeters.

[tex]h[/tex] - Height of the triangle, measured in centimeters.

If we know that [tex]b = 18\,cm[/tex] and [tex]h = 12\,cm[/tex], then the value of each equal length within the isosceles triangle is:

[tex]l =\sqrt{\frac{(18\,cm)^{2}}{4}+(12\,cm)^{2}}[/tex]

[tex]l = 15\,cm[/tex]

The length of the equal sides is 15 centimeters.

The ball will hit the ground 5 seconds after being thrown.

Step-by-step explanation:

The correct function is: h(t)= -16t^2+64t+80

You can rewrite the Quadratic function given in the exercise with making h(t)=0. Then this is:

0= -16t^2+64t+80

Now you can simplify the equation dividing both sides by -16. So you get:

0= t^2-4t-5

To find the solution of the Quadratic equation, you can factor it. In order to do this, it is necessary to find two numbers whose sum is -4 and whose product is -5. These number would be -5 and 1.

Therefore, you get this result:

0= (t-5) (t+1)

t1=5

t2=-1

Since the time cannot be negative, you can conclude that the ball will hit the ground 5 seconds after being thrown.

Answer:

The coordinates of H after the dilation is (-6,6)

Step-by-step explanation:

Here, we want to get the coordinates of the image given the coordinates of the pre-image

with the dilation factor and the coordinates, what we have to do is to simply multiply each of the coordinates of the point on the vertex by 3

Mathematically, we have this as;

H’ = 3H

so;

(-2,2) becomes; (3 * -2, 3 * 2) = (-6,6)

p = 76 a = 330 so your answer is D

The perimeter of the polygon is 76ft and Area is 338 sq.ft, the correct option is A.

A polygon is a closed structure with 3 or more than 3 sides.

The given polygon has 4 sides, so it is a quadrilateral

To find the area of the polygon, it can be divided into a rectangle and a triangle as shown

Area of Rectangle = Length * Width

Area of Triangle = (1/2) * base * height

Area of Rectangle = 15 *18

Area of Rectangle = 270 sq.ft

Area of Triangle = (1/2) * 8 *17

Area of Triangle = 4 * 17

Area of Triangle = 68 sq.ft

Therefore, the total area = 68 +270 = 338 sq.ft.

Perimeter of a polygon is equal to sum of all the sides

= ( 15+18+17+18+8)

= 76 ft.

Answer:

x=12 but who knows maybe

Step-by-step explanation:

if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.

Answer: The correct answer might be 6

Step-by-step explanation:

Given
