Answer:  the factor that we can multiply by itself to get that number

Step-by-step explanation:

For example, the square root of 4, is 2 because 2*2 is 4.

Answer:

the root of the number- by finding the square root you're finding the number you have to multiply by itself to get the number you were give

well, since arc's length is s = rθ where θ is in radians, and in the Unit Circle r = 1 and we also know that θ = 5π radians, then

s = (1)(5π)

s = 5π.

Answer:

32°

Step-by-step explanation:

Complementary angles sum to 90°

the complement of 58° is

90° - 58° = 32°

Complementary angles add up to [tex]\sf{90^\circ}[/tex].

In order to find the complement of the given angle, we should set up the following equation:-

(let n be the unknown angle)

[tex]\sf{n+58=90}[/tex]

Subtract 58 from both sides:-

[tex]\bigstar{\boxed{\pmb{n=32}}[/tex]

Hence, the complement of the angle is 32 degrees.

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

Answer:

C ≈81.64 inches

Step-by-step explanation:

Formula : C ≈ πd

Where:

C = circumference

π ≈ 3.14 {About}

d = diameter

As Given :

Wheel of a bike has a diameter of 26 inches.

Solution:

Note - Given that diameter = 26

π ≈ 3.14 {About}

C ≈ 3.14 (26)

C ≈ 81.64

Therefore the circumference of the wheel is 81.64 inches

To find the surface area, we must define what is the surface area

In this case, we have a cube

  ⇒ which means all the sides have equal areas since all the side lengths

      are equal

That means the surface area

  ⇒ is equal to ⇒ 6 * (Area of One Side)        

        '6' comes from the # of sides on a cube

Surface Area = [tex]6 *\frac{1}{9} *\frac{1}{9} = \frac{6}{9 *9} =\frac{2*3}{3*3*3*3} =[/tex] 2/27

Answer:

60 miles

Step-by-step explanation:

[tex]\frac{1}{8}*\frac{7.5}{7.5}=\frac{7.5}{60}[/tex]

Remember these are ratios!

Hence, they are 60 miles apart

Step-by-step explanation:

oh, come on ! you really cannot figure that one out ?

as there are 3 ft in 1 yd, 6 yd are then 6×3 = 18 ft.

so, 18 ft cost $2.88

1 ft costs then 2.88/18 = $0.16

The pooled sample proportion requires two samples combined to estimate the single p instead of estimating p1 and p2 separately. Therefore, it's true.

It should be noted that the pooled sample of a proportion is the weighted average of the proportion from the two samples.

In this case, the combined pool sample is called the poooled sample proportion and it's used in expression of the standard error.

In conclusion, the correct option is true.

Answer: Choice C  

Mean = 37.1

==================================================

Explanation:

Refer to the table below. The colum labeled "M" is the midpoint for each age interval. To find the midpoint, add up the endpoints and divide by 2. For example, the midpoint of 18 and 24 is (18+24)/2 = 42/2 = 21. Notice how the values of M are increasing by 7 each time.

The column labeled fM refers to multiplying the frequency f with the midpoint M. Example: fM = 6*21 = 126 in the first row.

Add up everything in the column labeled fM and you should get 1484. Divide this over the sum of the frequencies (40) and the mean is 1484/40 = 37.1

Perpendicular lines have negative reciprocal slopes. That means the fraction is flipped and multiplied by negative 1. So if one line has a slope of 3/5, then a line perpendicular to it has a slope of -5/3.

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line

Answer:

D. 102.6 in²

Step-by-step explanation:

The area of the square is 9 in² (3 × 3 = 9)

The area of the rectangle is 30 in² (3 × 10 = 30)

The area of the circle is 63.585 (a = πr², a = 3.14 × 4.5² - remember that the radius of a circle is half of the diameter)

Now, we can add these numbers together. 9 + 30 + 63.585 is 102.585 in² which is 102.6 in² rounded to 1 decimal place.

Hope this helps!

Answer:

Option D

Step-by-step explanation:

Square:

side = 3 in

[tex]\bf \boxed{\text{Area of square = side *side}}[/tex]

                        = 3*3

                        = 9 square inches

Rectangle:

length = 10 in

width = 3 in

[tex]\boxed{\text{Area of rectangle = length * width}}[/tex]

                            = 10 *3

                           = 30 inches

Circle:

diameter = 9 in

radius = 9 ÷ 2 = 4.5 in

[tex]\boxed{ \text{Area of circle = $\pi r^{2}$}}[/tex]

                       = 3.14 * 4.5 *4.5

                        = 63.6 square inches

Total area = area of square + area of rectangle + area of circle

                  = 9 + 30 + 63.6

                  = 102.6 square inches

Answer:

1. 10

2. 4

3. 8

Step-by-step explanation:

You have to fill in the given values for y and undo in reverse order to find x.

1. y = 6

6 = x - 4

6 (+ 4) = x - 4 (+ 4)

10 = x

2. y = 0

0 = x - 4

0 (+ 4 ) = x - 4 (+ 4)

4 = x

3. y = 4

4 = x - 4

4 (+ 4) = x - 4 (+ 4)

8 = x

Answer:

  √446 ≈ 21.12 cm

Step-by-step explanation:

The longest dimension of a rectangular prism is the length of the space diagonal from one corner to the opposite corner through the center of the prism. The Pythagorean theorm tells you the square of its length is the sum of the squares of the dimensions of the prism:

  d² = (15 cm)² +(11 cm)² +(10 cm)² = (225 +121 +100) cm² = 446 cm²

  d = √446 cm ≈ 21.12 cm

The longest line segment that can be drawn in a right rectangular prism is about 21.12 cm.

The square of the face diagonal is the sum of the squares of the dimensions of that face. The square of the space diagonal will be the sum of that square and the square of the remaining prism dimenaion, hence the sum of squares of all three prism dimensions.

Answer:

To get the discount for the 5 pound bag of apples, we must first note the following:

The original price of the apples, which in this case it is 2.99

Also we must note the sale price for the apples which is 1.59

to get the discount for apples we must then create an equation based on the above information,

Discount for A= original price -sale price

Discount for A=2.99-1.59

Discount for A=1.40

Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.

Part 2

To get the discount for oranges we follow the same steps.

Discount for R= Original price for R -sale price for R

Discount for R=3.99-2.59

Discount for R=1.40

In conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:

D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)
