Prism volume will be base area times height.  We have a right triangular base, so its area is half the product of its legs, area (1/2)(6)(8)=24.  The prism has a height 13.  Multiplying we get a volume of 24×13 = 312 cubic inches.

Answer:  312 cubic inches

Suppose that y varies inversely with x. Given x=-3 when y=-105. Find y when x=15

Answers

Answer:

21

Step-by-step explanation:

It is given that y varies inversely with x.

[tex]y\propto \dfrac{1}{x}[/tex]

[tex]y=\dfrac{k}{x}[/tex]       ...(i)

where, k is constant of proportionality.

It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.

[tex]-105=\dfrac{k}{-3}[/tex]

[tex]-105\times (-3)=k[/tex]

[tex]315=k[/tex]

Now,

[tex]y=\dfrac{315}{x}[/tex]

Substitute x=15 in the above equation.

[tex]y=\dfrac{315}{15}[/tex]

[tex]y=21[/tex]

Therefore, the value of y is 21 when x=15.

Answer:

V =221.4 m^3

Step-by-step explanation:

The volume is given by

V = Bh

Where B is the area of the base

The base is the triangle

B = 1/2 (12) * 4.1

B = 24.6

The height of the figure is 9

V = 24.6 *9

V =221.4 m^3

Answer:

221.4 m³

Step-by-step explanation:

Volume = base area × height

Base area: ½ × 4.1 × 12 = 24.6 m²

height: 9 m

Volume = 24.6 × 9 = 221.4 m³

the area of a triangle is 36m² and the height is 9 m. find the length of the corresponding base​

Answers

Answer:

8 meters

Step-by-step explanation:

Since the formula for the area of a triangle is bh/2, if the height of the triangle is 9m then the base must be 8m. This is because that is the only number which, when multiplied by 9 and divided by 2, yields 36. Hope this helps!

Solve for x.

-30 = 5(x+1)​

Answers

Answer:

−30=5(x+1)

Step 1: Simplify both sides of the equation.

−30=5(x+1)

−30=(5)(x)+(5)(1)(Distribute)

−30=5x+5

Step 2: Flip the equation.

5x+5=−30

Step 3: Subtract 5 from both sides.

5x+5−5=−30−5

5x=−35

Step 4: Divide both sides by 5.

5x5=−355

x=−7

Answer:

x=−7

Answer:

x = -7

Step-by-step explanation:

Since this problem has the distributive property, we can simplify the problem.

-30 = 5x + 5

Now we have to subtract 5 from both sides because of the +5.

-35 = 5x

To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.

-7 = x

x = -7

Which shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin?

On a coordinate plane, a triangle has points X prime (negative 2, 2), Y prime (0, 6), Z prime (1, 1).

On a coordinate plane, a triangle has points X (2, negative 2), Y (6, 0), Z (1, 1).
On a coordinate plane, a triangle has points X (2, 2), Y (6, 0), and Z (1, negative 1).
On a coordinate plane, a triangle has points X (negative 2, negative 2), Y (6, 0), Z (negative 1, 1).
On a coordinate plane, a triangle has points X (negative 2, 2), Y (negative 6, 0), Z (negative 1, negative 1).

Answers

A rotation of 90° about the origin includes the interchange of the position of  x, and y in the ordered pair and a change of one of the signs of the pair.

The option that shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin is the option;

On a coordinate plane, a triangle has points X(2, 2), Y(6, 0), and Z(1, -1).

Reasons:

The given transformation the gives the X'Y'Z' = 90° rotation about the origin

The given coordinates of X'Y'Z' are;

X'(-2, 2), Y'(0, 6), and Z'(1, 1)

Required:

The figure that shows the preimage of X'Y'Z'

Solution:

Given that X'Y'Z' is obtained by the rotation of XYZ 90°, therefore, the

coordinates of XYZ are given by the rotation of X'Y'Z' in the reverse

direction either counterclockwise and clockwise.

(x, y) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] (-y, x)

(x, y) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] (y, -x)

Therefore, we have;

X'(-2, 2) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] X(-2, -2)

Y'(0, 6) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Y(-6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Z(-1, 1)

Similarly, we get;

X'(-2, 2) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  X(2, 2)

Y'(0, 6) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  Y(6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] Z(1, -1)

The above coordinates of XYZ; X(2, 2), Y(6, 0), and Z(1, -1), corresponds to

the option;

On a coordinate plane, a triangle has points X(2, 2), Y(6, 0), and Z(1, -1).

Therefore, XYZ was rotated 90° clockwise to form X'Y'Z'

Answers

Answer:

The answer is D

Step-by-step explanation:

I subtracted 10 from 75 and got 65 then divided 65 by 3 and got 21

The answer is c.

An inequality solution is any value of the variable that makes the inequality true. Solving linear inequalities is almost exactly like solving linear equations.

How to find which value for x will make 3x + 10 > 75 correct?

Subtract 10 from both sides we get , 3x+ 10 - 10 = 75 - 10

3x + 0 > 65

divide both sides by 3 implies

3x / 3 = 65 /3

=> x > 15.

Thus Option c is correct.

Kelly rolls two number cubes 50 times. After each roll, she records whether the number on
each cube is even (E) or odd (O). Her results are shown in the graph. Based on Kelly's results,
which is the most reasonable prediction for the number of times two odd numbers will occur
when two number cubes are rolled 2,000 times?​

Answers

Answer:

480

Step-by-step explanation:

First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.

Hope this helped!

Using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

What is fraction?

A fraction is " a number is expressed as a quotient  in which numerator is divided by denominator".

According to the question,

Kelly rolls two number cubes 50 times, each cube is even (E) or odd (O).

The graph shows frequency of two numbered cube roll. The frequency of getting EO is 14, frequency of getting OE is 8, frequency of getting EE is 16 , frequency of getting OO is 12.

Total number of frequency = 14 + 8 + 16 + 12

= 50

The fraction of getting two odd numbers when cube is rolled 50 times

= [tex]\frac{12}{50}[/tex].               →(1)

In order to find, when two number cubes are rolled 2,000 times the number of times two odd numbers will occur.

= [tex]\frac{x}{2000}[/tex].            →(2)

Equating two fraction, to get value of 'x'.

[tex]\frac{12}{50} = \frac{x}{2000}[/tex]

[tex]\frac{12*2000}{50}[/tex]  = x

x = 12 × 40

x = 480.

Hence, using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.
