Answer 1

Answer:

1 : 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Radius (r) = 10 cm

Height (h) = 15 cm

Ratio of TSA and CSA =?

Next, we shall determine the total surface area (TSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Total surface area (TSA) of the cylinder =?

TSA = 2πr(r + H)

TSA = 2 × 3.14 × (10 + 15)

TSA = 6.28 × 25

TSA = 157 cm²

Next, we shall determine the curve surface area (CSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Curve surface area (CSA) of cylinder =?

CSA = 2πrh

CSA = 2 × 3.14 × 10 × 15

CSA = 942 cm²

Finally, we shall determine the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder. This can be obtained as follow:

TSA = 157 cm²

CSA = 942 cm²

Ratio of TSA and CSA =?

TSA : CSA = 157 / 942

TSA : CSA = 1 / 6

TSA : CSA = 1 : 6

Thus, the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder is 1 : 6

One side of a Rubiks cube puzzle has an area of 4 inches. What is the volume of the cube?

Answers

8 cubic inches 4/2 sides give at the length then length by width by height and a cube is all the same so 2x2x2

Find the length of a side:

Length of side = √area

Side = √4

Side = 2 inches.

Now calculate Volume:

The side lengths of A'A and B'B are 18 and 9 respectively.

What are similar triangles?

When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.

Given that, segment A'B' is parallel to segment AB.

Let A'A =x and B'B = y.

Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.

As per the property of similar triangles, it follows:

12/8 = (12 + x)/20

12 + x = (12/8)20

x = 18

And,

6/8 = (6+y)/20

6 + y = (6/8)20

y = 9

Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

Answer:

The awnser would be 9 because its under the sum of 10

Answer:

9 (see below)

Step-by-step explanation:

So, for a triangle, if you add any two sides, it will always be greater than the third side.

So if a triangle has sides of 1, 1, and 1:

1 + 1 > 1

So this is a triangle.

For a triangle with the sides of 3, 3, and 9:

3 + 9 > 3

9 + 3 > 3

3 + 3 > 9 (this one is not true)

So, these can't be the values of the sides of a triangle.

For your situation, you have a triangle with sides of 4, 6, and x.

We need to find out what x is, so:

4 + 6 > x

4 + x > 6

6 + x > 4

Isolate x to one side and simplify all the inequalities. You will get:

x < 10

x > 2

x > -2

So, -2 < x < 10.

If you plug in your answer choices, it will be 9.

Solve for xxx. -30=5(x+1)

Answers

EQUATIONExercise: -30 = 5(x + 1)

First, apply the distributive property:

-30 = 5(x + 1)

-30 = 5x + 5

Substract 5 from both sides:

-30 - 5 = 5x + 5 - 5

-35 = 5x

Divide both sides by 5:

[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]

[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]

‎

Let's check the answer:

-30 = 5(x + 1)

-30 = 5(-7 + 1)

-30 = 5(-6)

-30 = -30

The answer is correct.
