Find The Length Of Arc AB. Use 3.14 For Pi. Round To The Nearest Tenth.

Answers

Answer 1

Answer:

arc AB = 12.40°

Step-by-step explanation:

diameter = 7.9 x 2 = 15.8

circumference = 15.8 x 3.14 = 49.612

since the central angle of arc AB is 90 °

90/360 x 49.612 = 12.40

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

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.

[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:

What is margin of error?

In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.

Given that,

[tex]\^p[/tex] = 0.5

1 - [tex]\^p[/tex]  = 1 - 0.5= 0.5

margin of error = E = 5% = 0.05

At 90% confidence level

= 1 - 0.90 = 0.10

0.10/2 =0.05

Z/2 = 1.645 ( Using z table )

Sample size = n = (Z/2 / E)² x   (1 - [tex]\^p[/tex])²

= (1.645 / 0.05)² * 0.5 x 0.5

=270.6

Sample size = 271

The required sample size is 271.
