the number of degree in the central angle

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

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.

Answer:

8.49 feet

Step-by-step explanation:

Characteristics of a rectangle

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

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

[tex]\frac{5}{10}<\frac{3}{6}[/tex]

[tex]\frac{1}{2}>\frac{1}{3}[/tex]

[tex]\frac{4}{8}>\frac{2}{6}[/tex]

[tex]\frac{3}{5}>\frac{4}{5}[/tex]

Required

Select the unit fractions

If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. [tex]\frac{1}{2}[/tex] and not as an inequality i.e. [tex]\frac{3}{5}>\frac{4}{5}[/tex]

Given the format of the question, what is required of the question is to select all correct inequality.

[tex](a)[/tex] [tex]\frac{1}{4} <\frac{1}{6}[/tex]

Convert to decimals

[tex]0.25 < 0.167[/tex] ---- This is not true because [tex]0.25 > 0.167[/tex]

[tex](b)[/tex] [tex]\frac{5}{10}<\frac{3}{6}[/tex]

Convert to decimals

[tex]0.5 < 0.5[/tex] ---- This is not true because [tex]0.5 = 0.5[/tex]

[tex](c)[/tex] [tex]\frac{1}{2}>\frac{1}{3}[/tex]

Convert to decimals

[tex]0.5 > 0.33[/tex] ---- This is true

[tex](d)[/tex] [tex]\frac{4}{8}>\frac{2}{6}[/tex]

Convert to decimals

[tex]0.5 > 0.33[/tex] ---- This is true

[tex](e)[/tex] [tex]\frac{3}{5}>\frac{4}{5}[/tex]

[tex]0.6 > 0.8[/tex] --- This is not true because [tex]0.6 < 0.8[/tex]

So: the true inequality is:

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

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: 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]

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.
