Finding the area of a circle and a square (and shaded areas), three problems.

Answer:

2 and 9

Step-by-step explanation:

-4 - (-6) = 2

6 - (-3) = 9

Hope this helps :)

Answer: 2, 9

Step-by-step explanation:

Equation 1

-4 - (-6)

-4+6= 2

This is because whenever you have a number minus a negative number like x - (-y), you cross out the 2 minuses and make them a +.  Let's do the same for the 2nd equation:

6-(-3)

As I mentioned, the 2 minuses become a plus, so you just get rid of them. Now, we have 6+3

6+3= 9

If you're speaking of a sphere the circumference is d^2pi. Area=4/3r^3pi.

Answer:

[tex]\huge\boxed{\bf\:0.5 \: dollars }[/tex]

Step-by-step explanation:

Given,

We need to find the unit price OR the price of 1 plastic cup.

To find this, we need to divide the cost of the total nunber of cups bought by the number of cups bought. Then,

Cost of 1 cup

= Cost of 9 cups/9

= 4.51 / 9

= $ 0.5 (rounded price)

[tex]\rule{150}{2}[/tex]

Answer:

50 cents or $0.50

Step-by-step explanation:

c = the cost of each plastic cup, the unit price.

9c = 4.51

/9     /9

c = $0.50 per cup

Each cup costs 50 cents or $0.50

Hope this helps!

Answer:

20000

Step-by-step explanation:

16 and 2/3 of 1200:

[tex]= \left(16 + \dfrac23\right) \times 1200[/tex]

[tex]=(16 \times 1200)+ \left(\dfrac23\times 1200\right)[/tex]

[tex]=19200+ \dfrac{2400}3[/tex]

[tex]=19200+800[/tex]

[tex]=20000[/tex]

Or you can convert the mixed number into an improper fraction:

[tex]= \left(16 + \dfrac23\right) \times 1200[/tex]

[tex]= \left( \dfrac{16\times 3+2}3\right) \times 1200[/tex]

[tex]= \dfrac{50}3 \times 1200[/tex]

[tex]= \dfrac{50 \times 1200}3[/tex]

[tex]= \dfrac{60000}3[/tex]

[tex]=20000[/tex]

Answer:

8/21

Step-by-step explanation:

thanks for the points, the answer is right guys

Answer:

1) no, (2,3) is not a solution of y=x.

2) yes, (1,1) is a solution of y=3x-2

Step-by-step explanation:

When you have a point, the first number is x and the second number is y, (x,y).

If you substitute the numbers in for x and y, you will get a true statement if the point is a solution.

Look at y = x, put in 2 for x and 3 for y.

You get 3 = 2, that's false. So (2,3) is NOT a solution of y = x.

Then consider

y = 3x - 2; fill in 1 for x and 1 for y

You get

1 = 3(1) - 2

1 = 1 , a true statement. So (1,1) IS a solution.

Answer:

(2, 3) is not an ordered pair for y = 3x - 2.

Step-by-step explanation:

(2,3)

y = 3x - 2

3 = 3(2) - 2

3 = 6 - 2

3 = 4

This means that (2, 3) is not an ordered pair for y = 3x - 2.

Answer:

Number 8: The medium pizza is 19 inches bigger than the personal sized.

Number 9: The window will take up about 37.7 feet.  

Step-by-step explanation:

For number 8, you want to multiply the 16 inches by pi, and you would get an estimate of 50. Then you do the same thing for ten inches and you get an estimate of 31. Subtract the two estimates and you will get 19. Therefore, with the rounded up to a whole number estimate, the medium sized pizza is 19 inches bigger than the personal sized one.

For number 9, you want to multiply that radius, which is 6, by two to get your diameter. Then you want to multiply that to get your circumference, which would be a rounded up to the tenth place estimate of 37.7 feet.

I hope all of this helps you!

Answer:

8. 19 in.

9. [tex]113\ ft^2[/tex]

Step-by-step explanation:

8a. medium-sized pizza

d/2 = 2

r = 16/2 = 8 in.

C = 2*π*r

C = 2*3.14*8

C = 16*3.14

C = 50.24 in.

8b. personal-sized pizza

d/2 = 2

r = 10/2 = 5 in.

C = 2*π*r

C = 2*3.14*5

C = 10*3.14

C = 31.4 in.

50.24 in. - 31.4 in = 18.84 in.

19 in. (rounded to the nearest whole number)  <== final answer

9. Area of a circle: [tex]\pi r^2[/tex]

A = [tex]3.14* 6^2[/tex]

A = 3.14 * 36

A = [tex]113.04\ ft^2[/tex]

A = [tex]113\ ft^2[/tex] (rounded to the nearest tenth) <== final answer

Hope this helps!

Answer:

C

Step-by-step explanation:

Line slope calculation formula: The difference of the second components is divided by the difference of the first components. It should be noted that they are reduced in order. The components of a point on the numerator and denominator must always be written first.

Answer:

C

Step-by-step explanation:

Slope formula:

[tex]\mathsf{slope=\dfrac{(y_2-y_1)}{(x_2-x_1)}}[/tex]

where [tex]\mathsf{(x_1,y_1)}[/tex] and [tex]\mathsf{(x_2,y_2)}[/tex] are points on the line

Given:

[tex]\mathsf{slope=\dfrac{(-4-6)}{(-7-3)}}[/tex]

Answer:

A. x + 1 < 17

Step-by-step explanation:

An elevator at a department store must carry fewer than 17 people at a time. An elevator operator is present in the elevator at all times. If x customers can travel in the elevator with the elevator operator, which inequality represents this situation?

x = customers

1 = the elevator operator

< 17 = the amount of people that can be in the elevator at a time

Together, we get our inequality:

x + 1 < 17

The customers + the operator in the elevator should not be greater than 17.

Hope this helps!

Perimeter: 6+[tex]9\sqrt{2}[/tex] units

Area: 13.5 [tex]units^{2}[/tex]

Step-by-step explanation:

I wasn't sure what to estimate to...

for perimeter use: [tex]a^{2} +b^{2} =c^{2}[/tex]

I noticed that the trapezoid was made up of 3 identical triangles, so find the area of one of them times 3

one triangle area: [tex]\frac{1}{2}[/tex] (b · h)    b = base, h = height

plug- in values, so [tex]\frac{1}{2}[/tex] (3 · 3) is half of 9 which is 4.5.

3 · 4.5 is 13.5

Answer:

[tex]40^{3}[/tex]

Step-by-step explanation:

given that 1 cube = 1m,

5 cubes = 5m,

2 cubes= 2 m and

4 cubes = 4m

length = 5m, width = 2m and height = 4m

volume = length x width x height

             = 5 x 2 x 4

             = [tex]40^{3}[/tex]

Answer:

Step-by-step explanation:

i took the test :)

The number of crates that weigh less than 99.5 pounds is 4 crates.

A box plot has 5 data description.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

For this case, we're specified that:

Plot defined by points at 84, 99.5, 113, 143, 170

So, we have:

Minimum at 84, first quartile = 99.5, second quartile = median = 113, third quartile = 143, maximum value = 170

We want to know the amount of crates that weigh less than 99.5 pounds.

Assuming that data of the weights of the crates was arranged increasingly from left to right, as the first quartile is 99.5 and first quartile has 25% of data in its left, we get that 25% of the crates weigh less than 99.5 pounds.

Now, since there are 19 crates, so its 25% is:

[tex]\dfrac{19}{100} \times 25 = 4.75[/tex]

Total 4 crates completely lie below fist quartile(99.5), so total 4 crates out of 19 crates considered weigh less than 99.5.
