What is the value of x?

x = 25

x = 180

x = 135

x = 20

What Is The Value Of X?x = 25x = 180x = 135x = 20

Answers

Answer 1

Answer:

x=20

Step-by-step explanation:

Since all the angles in any give triangle adds up to 180, we can make an equation from this geometry question. x+5+7x-5+x=180 (Adding all the angles). If you simplify this, it becomes 9x=180, or x=20.

Samuel is a teacher and takes home 75 papers to grade over the weekend. He can grade at a rate of 7 papers per hour. How many papers would Samuel have remaining to grade after working for 8 hours?

Answers

Answer: 19

Step-by-step explanation:

75 papers need to be marked

He grades 7 papers per hour

To find out how many paper he graded in 8 hours:

7 x 8

(7 is the number of papers graded in an hour)

(8 is the number of hours)

7 x 8 = 56

(56 is the number of papers he graded in 8 hours)

Now, there was a total of 75.

To find the remaining number of test sheets:

75 - 56

(75 is the total number of papers)

(56 is the number of papers graded)

75 - 56 = 19

Therefore, there are 19 papers remaining to grade.

The area of a sector is. What does the variable n represent?

Answers

the number of degree in the central angle

N is the degree of the central angle of the sector.

What is sector in an angle?

The sector angle is the angle subtended between two radii of circle to the center of Circle.

If the radius of the circle is 10 inches, and the central angle of the sector is 90 degrees, the area of the sector can be found as follows:

90/360 * (3.14 * 10^2).

Following the order of operations, the equation proceeds as follows:

1/4 * (3.14 * 100) = 1/4 * 314 = 78.5.

Thus, the area of the sector is 78.5 square inches.

The formula to find the area of a sector is A = N/360 x (pi x r^2).

A sector is a section of a circle. In the formula given, A is the area of the sector,

N is the degree of the central angle of the sector, pi is an irrational number that can be rounded to 3.14, and r is the length of the radius of the circle.

Hence,  N is the degree of the central angle of the sector.

The width of a rectangle is 7 feet and the diagonal legnth of the rectangle is 11 feet. Which measurement is closest to the length of this rectangle in feet?

Answers

Answer:

8.49 feet

Step-by-step explanation:

Characteristics of a rectangle

A rectangle is a quadrilateral It has two parallel sides the diagonals of a rectangle bisect each other and they are equal in length

One diagonal of a rectangle divides a rectangle into two right angled triangles. Thus, the length of the rectangle can be determined using the Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length = ?

b = width = 7

c = diagonal = 11

7² + a² = 11²

49² + a² = 121²

a² = 121 - 49

a² = 72

calculate the square root of 72

a = 8.49 feet

Answers

Given:

Output = 5 times input

To find:

The graph for the given statement.

Solution:

We know that, y-axis represents the output and x-axis represents the input.

Let y be the output and x be the input. Then the given statement can be written as

[tex]y=5x[/tex]

Here, the slope of the line is 5 because the value of [tex]m[/tex] is 5 on comparing the equation with [tex]y=mx+b[/tex].

It means the line is steeper because the vertical change is greater than the horizontal change.

Therefore, the correct option is A.

Todd uses white tiles and some black tiles to make mosaic the mosaic has a total area of 144 square centimeters each tile has an area of 3 square centimeters how many black tiles did Todd use

Answers

Answer:

27 tiles

Step-by-step explanation:

Here is the complete question :

Todd uses 21 white tiles and some black tiles to make a mosaic.the mosaic has a total area of 144 square centimeters. Each tile has an area of 3 square centimeters. How many black tiles did Todd use

Steps to take to determine the answer

Determine the total area of the white tiles used. This can be determined by multiplying the number of white tiles by the area of a tilesubtract the area of the white tiles from the total area of the mosaic. Divide the answer derived in the previous step by 3

Area of the white tile = area of each tile x total white tiles used

3 x 21 = 63cm²

144cm² - 63cm² = 81cm²

Number of black tiles used = 81cm² / 3cm² = 27 tiles

Answer:

B. 200 cubic feet

Step-by-step explanation:

There are two prisms: the triangular prism and the rectangular prism

first lets start with the triangular one:

remember that for a right triangular prism (this one), the area is 1/2 x base x height x length

another way to think about it is to find the area of the triangle and then multiply that by the thickness

The base is 4 feet and the height is the same as the rectangular prism, which is 5

and the length is 4 ft (same as rectangular prism)

so 1/2 x 4 x 5 x 4 is 40

next lets do the rectangular prism

remember the volume is length x width x height

8 x 4 x 5 = 160

now we simply add the volume of the two prisms

40 + 160 = 200

and there's you're answer :)

hope that helps!

Answer:

Step-by-step explanation:

Area of triangular face = 0.5×4×5 = 10 ft²

Volume of triangular prism = 10×4 = 40 ft³

Volume of rectangular prism = 8×4×5 = 160 ft³

Total volume = 40+160 = 200 ft³

A bus and a car both drive 145 miles from town A to town B. The bus drives 8 miles per hour faster than the car. If it takes the car 2 hours and 54 minutes to arrive, how long does it take for the bus to arrive?

Answers

Answer: 2.5 hours

Step-by-step explanation:

Given

Distance between A to B town is [tex]d=145\ miles[/tex]

Bus speed is 9 miles per hour faster than car

time taken by car is 2 hours and 54 minutes i.e.

[tex]t=2+\dfrac{54}{60}=2+0.9=2.9\ hr[/tex]

Speed of car is v

[tex]\Rightarrow v=\dfrac{d}{t}=\dfrac{145}{2.9}=50\ mph[/tex]

Speed of bus is [tex]v+8=50+8=58\ mph[/tex]

time taken by bus is t'

[tex]\Rightarrow t'=\dfrac{d}{v+8}=\dfrac{145}{58}=2.5\ hr\\\\\\\Rightarrow t'=2\ hr\ \text{and}\ 30\ \text{minutes}[/tex]
