Answers

Answer:

It's the first expression

Step-by-step explanation:

9 (4a minus 3)

(9x4a)-(9x3)

36a minus 27

The correct expression equivalent to 36a minus 27 is 9(4a minus 3)

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, an expression is 36a minus 27, we need to find an expression equivalent to the given expression,

So, converting the expression into mathematical expression,

36a minus 27

= 36a-27

HCF of 36 and 27 is 9, so taking 9 common,

Therefore,

36a-27 = 9(4a-9)

We can write 9(4a-9) in statement,

9(4a-9) = 9(4a minus 3)

Hence, the correct expression equivalent to 36a minus 27 is 9(4a minus 3)

To finish a project, you need to paint the lateral surfaces of a cube with side length 2.5 inches. Find the area that you need to paint.

Answers

Answer:

[tex]25 in^2[/tex]

Step-by-step explanation:

We want to find the lateral surface area of the cube.

The lateral surface area of a cube is given as:

[tex]A = 4a^2[/tex]

where a = length of side of the cube

Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:

[tex]A = 4 * 2.5^2\\A = 25 in^2[/tex]

The volume of a cylinder is 40 ft which expression represents the volume of O.C. one with the same base and height as the cylinder

The volume of a cylinder is 40 ft which expression represents the volume of a Cone with the same base and height as the cylinder?

3(40) ft³

3(1/40) ft³

1/3(40)ft³

1/3(40²) ft³

Answer:

The expression  that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³

Step-by-step explanation:

To find the expression that represents  the volume of a cone with the same height and base as the cylinder, we will follow the steps below:

First write down the formula for calculating volume of a cone   and volume of a cylinder

volume of a cone = [tex]\frac{1}{3}[/tex] πr²h

volume of a cylinder = πr²h

If the base are the same, this implies they have the same radius,  and from the question, it states that they have the same height, hence;

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

from the question, the volume of the cylinder is 40 ft³

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

                              = [tex]\frac{1}{3}[/tex] (40) ft³

volume of a cone =  [tex]\frac{1}{3}[/tex] (40) ft³

Therefore the expression  that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³

Jack has 20 unit cubes. How many rectangular prisms with different sized bases can he build with the cubes?

Answers

Answer:

Jack can form four rectangular prisms with 20 unit cubes.

Step-by-step explanation:

Number of unit cubes Jack has = 20

Factors of 20 = 1, 2, 4, 5, 10, 20

The possible dimensions of a rectangular prism that can be formed by these unit cubes may be,

1 × 1 × 20 (One cube at the base)

1 × 2 × 10 (2 cubes at the base)

1 × 4 × 5 (4 cubes at base in a single row)

2 × 2 × 5 (4 cubes at the base with 2 cubes in length and 2 cubes in width)

Therefore, Jack can form four rectangular prisms with 20 unit cubes.

The height of an object launched upward from ground level is given by the function s(t) = -4.9t2 + 78.4t, where s(t) is the height in meters and t is the time in seconds. Arrange the time intervals in ascending order of the object's magnitude of average velocity over the interval.

Answers

Answer:

the distance of  the object before it  hits the ground after launch is t = 1.592 seconds

Step-by-step explanation:

The height of an object launched upward from ground level is given by the function s(t) = -4.9t² +7.8t

when the object reach the ground then s(t) = 0

So;  -4.9t² +7.8t = 0

-4.9t² +7.8t + 0 = 0

By using the quadratic equation

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

where; a = -4.9 ; b = 7.8 and c = 0

[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(7.8)^2-4(-4.9)(0)} }{2(-4.9)}}[/tex]

[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(60.84} }{-9.8}}[/tex]

[tex]\mathbf{=\dfrac{-(7.8) + \sqrt{(60.84} }{-9.8} \ \ \ \ OR \ \ \ \ \mathbf{\dfrac{-(7.8) - \sqrt{(60.84} }{-9.8}}}[/tex]

[tex]\mathbf{=0 \ \ \ OR \ \ \ 1.592 }}[/tex]

Hence;  the distance of  the object before it  hits the ground after launch is t = 1.592 seconds

Answer:

This means that if the drive was only two hours, they would have to leave home at 10:02 pm.

Answers

Answer:

It depends on the description you want to make. If you want to describe how separate is the data, then you would use a variation measure like a standard deviation which will compare each data with the mean.

On the other hand, if you want to measure how close the data is, then you would use central measures, like the mean or median, that will tell you the central value the whole data is pointing to.

Therefore, there's no bettter measures, it always depends on what aspect you want to highlight about the data set.
