hey the sentence isnt visible

Answer:

7.) 53.38

8.) 18.84

9.) 87.92

Step-by-step explanation:

7.)

For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.

The formula for finding the circumference is 2 × π × 8.5

2 × 3.14(π) = 6.28.

6.28 × 8.5 = 53.38

8.)

For the second question, we can see that the radius is now given to us which is 3ft.

The formula for finding the circumference is 2 × π × 3

2 × 3.14(π) = 6.28.

6.28 × 3 = 18.84

9.)

For the third question the raduis is also given to us, which is 14 in.

The formula for finding the circumference is 2 × π × 14.

2 × 3.14(π) = 6.28.

6.28 × 14 = 87.92

Answer:

132cm^2

Step-by-step explanation:

first break the shape up into component shapes. the shape is made of two rectangles and two triangles. the area for a rectangle is A=BH where b is base and h is height. the area of a right triangle is BH/2 where b is the base and h is the height. you are given the base and height of the top rectangle 4x7. To find the area of the triangles and the second rectangle you have to do some algebra. the total base length is 19cm and the top rectangle has a length of 7cm so 19-7 leaves you with 12cm to spare and there is two symmetric triangles on each side so 12/2 is 6. now we know all the measurements and can solve.

Step-by-step explanation:

Absolute value bars ask for the distance of a number and 0 so |-8| is equal to 8 since it is 8 units away from zero, |7| would be equal to 7 since it is 7 units away from 0. To do the more complicated problems simplify the equation as much as possible and then solve.

Answer:

87

Step-by-step explanation:

9 x 10 = 90, the store had 90 bags in total at the start. 90 - 3 = 87, the store had sold 87 bags of grapes during the anniversary.

The number of bags of grapes that they sell during the anniversary is 87 bags.

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given that,

For a grocery store's 25 years anniversary sale they ordered 9 crates of grapes with each create containing 10 bags of grapes.

Number of crates of grapes ordered = 9

Number of bags of grapes in each crate = 10 bags.

Total number of bags in 9 crates = 90 bags

After the anniversary sale they had sold all but 3 bags.

Number of bags of grapes sold = 90 - 3 = 87 bags

Hence the number of bags of grapes sold is 87 bags.

1 gallon = 4 quarts

1 quart = 2 pints

1 pint = 2 cups

1 cup = 8 ounces

Answer:

A. ∠G ≅ ∠L   AND  B. ∠Q ≅ ∠V

Step-by-step explanation:

This is because the others although they are both initially opposite and seen as vertical they have a secondary line that alters the angle and so the last two angles that have this are not vertical

Step-by-step explanation:

since each goes along with 5, we know that 5 will time x + 8

we then see adding 8 to that team with becomes +8

we have a total so 75 t will be our end result value, and then we put these parts together.

Step-by-step explanation:

Answer:

22x - 14

Step-by-step explanation:

pretty sure its like this..

3(4x-3)+5(2x-1)

= 3×4x + 3×(-3) + 5×2x + 5×(-1)

= 12x + (-9) + 10x + (-5)

and according to the rules of multiplying negative by positive...

= 12x - 9 + 10x - 5

combine like terms using the symbols on its left

= 12x + 10x - 9 - 5

= 22x - 14
