Answer:

3 In²

Step-by-step explanation:

Talking about surface area, the total area of an object is taken into consideration.

NB: Kindly check the attached picture for the diagram of the 3D object.

In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.

Surface Area = 6 × k².

Surface area = 6 × ( 1.8 × 1.8) cm².

Surface Area = 19.44 cm².

The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------>  x in².

19.44 × 0.155 in² = 3 in².

Once you find that just multiply 18 by how much of a difference there is.

The difference is 4. You must add 4.

Answer:

455 ( I think )

Step-by-step explanation:

Lets start with the red shape.

The triangle on top is 5x3, and the equation for a triangle is base•height•1/2

So each triangle equals 7.5, as 15/2=7.5. Remember there are 2 triangles so the total of both triangles is 15.

The front side of the red shape is 6x5, which equals 30.

Same with the back.

The side though, is 3x6, which equals 18.

So 15 (both triangles)+60 (the front and back of the shape)+18 (the side)= 93

The red shape is 93 inches cubed.

The green shape is a rectangular prism.

The sides, are both 3x7, which equals 21. Remember there are 2 sides so together they equal 42.

The next part is 3x16= 48. There are 2 of these so it equals 96.

The top and bottom is 7x16=112, which is 224.

42 (sides) + 96 (front and back) + 224 (top and bottom)= 362

The green shape is 362 inches cubed.

362+93=455 inches cubed as a total

Answer:

r > 7 (C)

Step-by-step explanation:

3r−7>14

Step 1: Add 7 to both sides.

3r−7+7>14+7

3r>21

Step 2: Divide both sides by 3.

Imagine this < as a alligater and itś eating the greater number!!

Answer:

C.) r ≥ 7

Step-by-step explanation:

1. Add 7 to each side to cancel it out and keep the sign the way it is to avoid confusion

3r - 7 ≥ 14

   + 7    +7

3r ≥ 21

2. Divide each side by 3 to get the variable alone

3r/3 = r

21/3 = 7

r ≥ 7

This means r is greater than or equal to 7, and it can also be written as 7 ≤ r

Answer:

60º

Step-by-step explanation:

A triangle is 180º so you do (180-60)/2 and you get that x=60.

Hope that helps :)

Answer:

Hey love! x = 60

Step-by-step explanation:

Because a triangle adds up to 180 so

180 - 60 = 120 and sense both angles will be the same measure I divide 120 by 2 and get 60 so

x =60 Hope that helps!

Answer:

Step-by-step explanation:

Since this is a rectangular prism, we need to do length × width × height to find the volume. Now despite the shape being tilted at an angle, nothing is different.

So we can see that the length is 25, the width is 18 and the height is 7

Rewrite the formula for volume replacing variables

25 × 18 × 7

Now solve.

25 × 18 = 450

450 × 7 = 3150

Now before we finalize our answer, there are two more things we need to do.

We need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

Add both of these to the end

3150 ft³ is your final answer

1. 3,6

2. 5,6

3. 4,5

(branliest will be appreciated and thanks)

The newer machine works at a unit rate of

(5400 cans) / (180 min) = 30 cans/min

while the older machine operates at

(5400 cans) / (217 min) ≈ 24.88 cans/min

So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about

(5400 cans) / (54.88 cans/min) ≈ 98.39 min

Answer:

t≥7

Step-by-step explanation:

11≤t+4

4 moves to the other side hence its sign changes

11-4≤t

7≤t

they change sides

t≥7

the sign was facing t so this does not change

Answer:

Step-by-step explanation:

Here are some steps to help you

Step 1

11 ≤ t + 4  We are gonna simplify

Step 2

11 ≤ t + 4  simplify

t+4≥11

Step 3

t+4≥11  Subtract 4 from the sides

t≥7

So therefore, your answer will be t≥7

-[tex]\frac{5}{9}[/tex]               -[tex]\frac{5}{9}[/tex]

leaving you with

____ = - [tex]\frac{5}{9}[/tex]

Answer:92.84

Step-by-step explanation: 39+27+13.5+13.5 because the two sides are longer than 12

The perimeter of the trapezium is 143.94 ft.

We have,

The perimeter of an isosceles trapezium can be found by adding the lengths of all four sides.

In this case, the trapezium has height = 12 ft and parallel sides of length 27 ft and 39 ft.

To find the length of the non-parallel sides we can use the Pythagorean theorem:

a² = (39 - 27/2)² + 12²

a² = 1440

a ≈ 37.95 ft

Therefore,

The perimeter of the trapezium is:

P = 27 + 39 + 2a

P ≈ 27 + 39 + 2(37.95)

P ≈ 143.9 ft

Rounding to the nearest hundredth place,

we get P ≈ 143.94 ft.

Thus,

The perimeter of the trapezium is 143.94 ft.
