Answer:

82.97cm^2

Step-by-step explanation:

Given data

Circumference=  131.88 centimeters

We want to find the area of 6/10 part of a circle

Firstly, let us find the area of the circle

We need to get the radius

C= 2πr

131.88= 2*3.142*r

131.88=6.284r

r=  131.88/6.284

r=20.98 cm

Area= πr^2

Area= 3.142*20.98^2

Area= 3.142*440.16

Area= 1382.98cm^2

Hence 6/10 of a 1382.98

=0.06*1382.98

=82.97cm^2

Answer:

ecall that 6 + 6 + 6 = 6 × 3

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42

Still by the same token,

2 + 2 + 2 + 2 = 2 × 4

Answer:

5

Step-by-step explanation:

first, change the fractions to decimals (.7 and 3.5)

then, divide .7 by 3.5 to get 5

3.5 ÷ .7 = 5

Answer:

You have 90 pages left.

Step-by-step explanation:

1/4 × 120 = 30 pages read

Therefore

120- 30

=90 pages left to read

Answer:

You read 30 pages of the book.

You have 90 pages left.

Step-by-step explanation:

120 total pages

⇒ 120 = 100%

[tex]\frac{1}{4}[/tex] pages have been read

⇒ [tex]\frac{1}{4}[/tex] = 25%

[tex]\frac{3}{4}[/tex] remaining

⇒ [tex]\frac{3}{4}[/tex] = 75%

120 x .25 = 30 pages read

120 x .75 = 90 pages unread

30 + 90 = 120

Answer: 353ft

Step-by-step explanation:

To work out what the area of this composite shape is, you would split it into two shapes; a square and a rectangle.

For the formula of the rectangle and square you would do base x height.

So,

For the square you do 13x13=169

For the rectangle you would do 23x8=184

Then to work out the total area of the two shapes you would add the two areas together.

169+184=353

Answer:

Step-by-step explanation:

I believe this question is coming from a statistical data, which for whatever reasons is not present here. If Julie says the most amount of time spent, it meant that the time most time people spent on the homework. And if she says the least amount of time. This means that the least number of time people spent on the homework.

Then again, she says it is half times, this means that if 5 people spent the most amount of time in doing something, then 10 people must have spent the least amount of time doing the same exact thing.

I hope you understand

Answer:

y = 1/2x + 5

Step-by-step explanation:

The formula for an equation is y = mx + b

m is the slope. It is given

y = 1/2x + b

b is the y-intercept

In this case, we must substitute to find the y-intercept

We are given coordinate pair (4,7)

Plug our pair in and we get => 7 = 1/2(4) + b

=> 7 = 2 + b

easily, we find b = 5

We get our equation: y = 1/2x + 5

Cheers!

Answer:

[tex]x=\sqrt{41}[/tex]

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2}+ b^{2}=c^{2}[/tex]

Answer:

Option B

Step-by-step explanation:

Pythagorean Theron is:

[tex]a^2+b^2=c^2\\\\\text{a and b - legs}\\\text{c - hypotenuse}[/tex]

We would be solving for 'c', or the hypotenuse.

[tex]4^2+5^2=c^2\\\\16+25=c^2\\\\41=c^2\\\\\boxed{\sqrt{41}, -\sqrt{41} =c}[/tex]

The correct answer should be option B.

Hope this helps.

Answer:

   the number of acres planted for a cost of $35,000

Step-by-step explanation:

If the function C gives the dollar cost of planting a certain acreage, then the inverse function C^-1 gives the acreage planted for a given dollar cost.

  C^-1(35000) gives the acreage planted for a cost of $35,000

Answer: 58.33π units ³

Step-by-step explanation:

The volume of a cylinder = πr²h

The volume of a cone = 1/3πr²h

Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:

= 175π / 3

= 175/3π

= 58.33π units ³

The volume of the cone is 58.33π units ³

Answer:

183

Step-by-step explanation:

When multiplied by pi, it rounds out to 183.
