Answer: C / 612 cubic cm

Step-by-step explanation: so it has a 3D figure with 6 rectangular faces to find the volume of the rectangular prism you need to multiply it 3 dimensions length x width x height. The volume is expressed in the cube units.

(Hope this helps)

Answer:

it is c because height is 13.6 and width is 5 and length is 9 the foumla for  volume is  height times length times width so 13.6 time 5 time 9

Step-by-step explanation:

Answer:

Following on from step 3

0 = (x + 1)(x + 3)

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values into either of the 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1 : y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3 : y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Step-by-step explanation:

The solutions that represents the system of the equation are (- 3, 5 ) and (- 1, 9 )

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

0 = (x + 1)(x + 3)

By equating each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values in 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1

y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3

y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Therefore, the solutions are (- 3, 5 ) and (- 1, 9 )

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

4 x 5 = 20

2 + 4 = 6

Soultion #1 = 2 + 5 + 4 + 3 = x

7 + 4 + 3 = x

11 + 3 = x

11 + 3 = 14

Solution #2 = 3 - 4 - 2 - 5 = x

-1 - 2 - 5 = x

- 1 + (-2) - 5 = x

1. Mean: 103

2. Median: 8

3. Mean would increase.

Step-by-step explanation:

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1,236

Then, 1,236/ 12 = 103

Therefore, our answer!

2. Put the numbers in order from least to greatest:

1, 6, 7, 8, 9, 11, 16

Cross out one on each side until you get to the middle.

3. Add up all original numbers to get a mean of: 2.7 and then add up all the numbers including six to get a mean of: 3.2 As you can see, the mean increased.

Hope this helps, good luck! :)

The Mean is 103 ,Median is 8 and Mean would increase

What is mean and median?

The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set.

The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number.

according to the question,

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1236

Then, 1236/ 12 = 103

Therefore, our answer

Answer:

60

Step-by-step explanation:

Answer:

60º

Step-by-step explanation:

Since the angle is a right angle, which is 90º, all you have to do to find angle s is subtract 30 from 90, which gives you 60

Answer:

Thus, the ratio of the central angles is 4 : 9.

Step-by-step explanation:

Area, A = 12 π square units

radius, R = 6 units

radius, r = 4 units

Area of sector is given by

[tex]A=\frac{\theta }{360}\times \pi r^{2}[/tex]

For first sector

[tex]12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}[/tex]

For second sector

[tex]12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}[/tex]

So, the ratio is

[tex]\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9[/tex]

Answer:

4 : 9

Step-by-step explanation:

Given:

Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.

Find ratio of central angles.

Solution:

Let A = central angle

Area of a sector = pi r^2 (A/360)

Since both sectors have the same area,

pi r1^2 (A1/360) = pi r2^2 (A2/360)

simplifying

A1 r1^2 = A2 r2^2

Therefore

A1 : A2  = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9
