Answer: 46 puzzles  

Step-by-step explanation:

There are 70 puzzles in total in the book.

Jackie has completed / of those puzzles. In whole numbers that is:

= 2 /5 * 70

= 28 puzzles

She then completes 18 more puzzles.

Total that she has completed is:

= 28 + 18

= 46 puzzles

Fomula to find a volume of a cylinder:

V=πr^2h

V=π(10)^2(15)

V≈4712.39ft

It's the fourth answer, y=10. This is because the line is a straigh line is 180 degrees, which is shown in the photo. You have to take away 120 degrees (the angle is the same on both sides) which would leave you with 60. Then, thats the sum of the angle, but since were solving for y, you have to divide 60 by 6, which gives you your answer, 10. Hope this helps, if you need anything else you can message me!

Answer:

y = -7

Step-by-step explanation:

5x+8y=29

5(17)+8y=29 (simplify by multiplying)

85+8y=29 (subtract 85 from both sides)

8y= -56 (divide both sides by 8y)

y = -7

Given:

The phrase is "six times a number is less than negative thirty-nine and three-quarters".

To find:

The inequality represented by the given phrase.

Solution:

Let x be the unknown number.

Six times a number is "6x".

Less than is "<".

Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".

So, six times a number is less than negative thirty-nine and three-quarters is:

[tex]6x<-39\dfrac{3}{4}[/tex]

Therefore, the correct option is C.

Answer:

"six times a number is less than negative thirty-nine and three-quarters".

Step-by-step explanation:

or C

Answer:

Step-by-step explanation:

If x is a positive number then y + x lies to the right of y, if x is a negative number then the location of y + x will be to the left, if x is zero then y and y + x are the same point

Answer:

5.86cm²

Step-by-step explanation:

Area of the shaded region = Area of the rectangle - Area of the circle

Area of rectangle = Length * Width

Area of rectangle = 3cm * 3cm

Area of rectangle = 9cm²

Area of the circle = πr²

Given radius r = 1cm

Area of the circle = 3.14(1)²

Area of the circle = 3.14cm²

Area of the shaded region = 9 - 3.14

Area of the shaded region = 5.86cm²

Answer:

5.86cm²

Step-by-step explanation:

Area of the shaded region = Area of the rectangle - Area of the circle

Area of rectangle = Length * Width

Area of rectangle = 3cm * 3cm

Area of rectangle = 9cm²

Area of the circle = πr²

Given radius r = 1cm

Area of the circle = 3.14(1)²

Area of the circle = 3.14cm²

Area of the shaded region = 9 - 3.14

Area of the shaded region = 5.86cm²

Answer:

You need to divide 20/11

20/11= 1.82

about 2 pounds

Answer:

Find the area by multiplying the base by the height. From the problem, the length (base) of the rectangle is 5 units. The height of the rectangle is

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

inches. Multiply to find the area.

[tex]5 \times 3 \frac{1}{2} = 17 \frac{1}{2} [/tex]

The area of the rectangle is 17 1/2 units squared. The answer you provided is correct!

Answer:

29

Step-by-step explanation:

18+15=23 8+21=29

Answer:

Step-by-step explanation:

Part A

x-intercepts of the graph represent the value of goods at which profit of of the company is zero → Break even of the company

Maximum value of the graph represents the maximum profit of the company at certain price of the goods.

Part B

Interval in which the function is increasing → x = 0 to x = $3

Profit of the company increases when price of the goods increase from 0 to 3.

Interval in which the function is decreasing → x = $3 to x = $6

Profit of the company decreases when the price of the goods increases from 3 to 6.

Part C

Average rate of change of the function from x = a and x = b,

= [tex]\frac{f(b)-f(a)}{b-a}[/tex]

By applying the same rule,

Average rate of change of the function between x = 1 and x = 3

= [tex]\frac{120-60}{3-1}[/tex]

= [tex]\frac{60}{2}[/tex]

= 30
