Find the value of x in the diagram below.

Find The Value Of X In The Diagram Below.

Answers

Answer 1

Answer:

10

Step-by-step explanation:

13x + 5x = 180

18x = 180

x = 10

Answer 2
A straight line is 180 degrees so what I did was add 5+13 to get 18.
180 divided by 18 = 10 so the answer is 10. To check my work I multiplied 5x10 which is 50 and 13x10 which is 130 and they add up to 180 degrees.

x is equal to 10.

Answer:

Option B; False

Step-by-step explanation:

Consider a Triangle Inequality to prove that these segments could form a triangle;

\(| a - b | < c < a + b,\\| c - a | < b < a + c,\\| c - b | < a < b + c, Considering - a - segment AC ( 8 units ) - b - BC ( 7 units ), - c - BC ( 15 units )\\\\| 8 - 7 | < 15 < 8 + 7,\\1 < 15 < 15, Now 15 is not < 15, it is =, thus ;\\Solution ; False\)

Answers

Answer:

D. 36.9

Explanation:

three-fifths of 61.5 is 36.9!

Answer:

D. 36.9

Step-by-step explanation:

The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!

A metal paperweight is in the shape of a cylinder. The paperweight has the height of 1.5 inches and a diameter of 2 inches. How much does the paperweight weigh if 1 cubic inch weighs 1.8 ounces? Round to the nearest tenth!

Answers

Answer:

8.5 ounces

Step-by-step explanation:

area of circle = pi*r^2

pi*1^2 = pi

pi*1.5 = 8.48 = 8.5

The weight of the paperweight is 8.5 ounces.

Concept:Firstly, we will calculate the volume of the cylinder by using the formula,
\(V = \pi r^2h\)Then, we will find the weight by multiplying volume with a specific weight.

How to solve the given question?For the given paperweight,
Diameter = 2 inches ⇒ Radius = 1 inchVolume of Cylinder, \(V = \pi r^2h\)
∴ \(V = \pi (1)^2 (1.5) = 4.72 \ inch^3\)As the weight of 1 cubic inch = 1.8 ounces
∴ Weight, W = 4.72 × 1.8 =  8.5 ounces

The weight of the paperweight is 8.5 ounces.

Tasha has foam blocks stored in a box that measures 2 1/4 ft long by 2 ft wide by 2 ft tall. Each foam block is a cube with 1/2ft edge length. How many blocks can fit into the box?

Answers

Answer:

72

Step-by-step explanation:

First, you need to calculate the volume of the box:

2 1/4 × 2 × 2 = 9 (ft³)

Second, calculate the volume of the foam block:

1/2 × 1/2 × 1/2 = 1/8 (ft³)

In the end, get the volume of the box divided to the volume of the foam block:

9 ÷ (1/8) = 72 ( foam blocks)

Conclusion, the answer is 72 foam blocks

Find the surface area of a top open cylinder

12 in radius
2 in height

Find the surface area of a top open cylinder 12 in radius 2 in height

Answers

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Brainlist for positive attitude and correct answer :D

Answers

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
