Answer:

sorry if this is confusing

Step-by-step explanation:

16 miles = 12 miles

------------ ----------------

20 mins. how many mins?

16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles

20 ? because 15 x 16 = 240

Answer:

Step-by-step explanation:

It crosses through (0,0) and has a slope of 2.5 or rather 5/2 because when the x value is at 4 the y value is at 10 that simplifies to 5/2 or 2.5.

Answer:

The legs are a and b, the hypotenuse is c

Step-by-step explanation:

The legs of a right triangle are the two smaller sides. The hypotenuse is the longest side it is also always opposite of the 90-degree angle. If you need to find the lengths of sides remember the Pythagorean theorem, .

Answer: c=-1,b=5,a=-5

Step-by-step explanation: If c=-1, substitute it into the second equation first. The second equation becomes -2b-1=-11, simplify it becomes -2b=-10, divide by 2 it becomes -b=-5, so b=5. Then you substitute b and c into the first equation. The first equation becomes a+5+-(-4)=4, simplify it becomes a+5+4=4, Simplify again it becomes a=-5.

Answer:

123 x h because you can't put them together but we can add the stuff that is already there so we get 123 and times h thats our answer

Answer:

Step-by-step explanation:

1 .

step 1:  multiply the 5 to the bracket =5p+10-p

step 2 : subtract the p from the 5 p =5p-p+10 = 4p+10

2.

step 1 : multiply the 3 to the bracket = 8h + 12h-18

step 2: add the 8h to the 12h  = 20h - 18

3.

multiply the 4 to the bracket = 4x+32 +9x

add 4 x to 9 x = 13x +32

4.

multiply the 2 to the bracket = 6y +8 +9

add the 8 to the 9 = 6y + 17

5.

multiply to six to the bracket =9x + 12x +18

add the 9 and 12 x = 21x+18

6 .

multiply the 3 to the bracket = 9m + 3 +2m

add the 9m to 2m = 11m+ 3

7.

multiply the 2 to the bracket = 2r + 18 -6

subtract the 18 from the six = 2r +12

8 .

multiply the five to the bracket = 15 d + 40

9.

multiply the 4 to the bracket = 8m+8+3m

add the 8 m to the 3 m = 11m + 8

10 .

multiply the 10 to the bracket= 5y +20 +10 y

add the 5y and the 10 y = 15y + 20

Answer:

C

Step-by-step explanation:

Given:

The ratio of the number of fiction books to the number of non-fiction books in a library is 5:2.

Total number of books = 1421

To find:

The number of books of each type.

Solution:

Let the number of fiction books be 5x and number of non-fiction books be 2x.

Total number of books = 1421

[tex]5x+2x=1421[/tex]

[tex]7x=1421[/tex]

[tex]x=\dfrac{1421}{7}[/tex]

[tex]x=203[/tex]

Now,

Number of fiction books : [tex]5(203)=1015[/tex]

Number of non-fiction books : [tex]2(203)=406[/tex]

Therefore, the number of fiction and non-fiction books are 1015 and 406 respectively.

Answer:

(D). (8, - 5)

Step-by-step explanation:

Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)

Coordinates of the midpoint are ( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

(x² - 10x + 25) + (y² + 2y + 1) = 25

(x - 5)² + (y + 1)² = 5²

(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)

5 = (2 + x) / 2 ⇒ x = 8

- 1 = (3 + y) / 2 ⇒ y = - 5

(D). (8, - 5)

Answer:

(y - i[tex]\sqrt{7}[/tex])(y + i[tex]\sqrt{7}[/tex])

Step-by-step explanation:

Factor as a difference of squares, that is

y² + 7

= y² - (i[tex]\sqrt{7}[/tex] )²

= (y - i[tex]\sqrt{7}[/tex])(y + i[tex]\sqrt{7}[/tex])

Answer:

C) y is equal to 10.5x

Step-by-step explanation:

$31.50 is charged for 3  hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50

this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x

and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.

9 + 2j

Answer:

Step-by-step explanation:

we will use ratio

magazines : cost

4 : $15

16 : $60

we will multiply 4 by 4 and 15 also by 4 so 16 magazines will cost $60

The cost of 16 magazines is $22.5.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Isabel bought 4 magazines for a total of $15.

The unit rate of the magazines,

= 15/4 = $3.75.

The cost of 16 magazines,

= 6 x 3.75

= $22.5

Therefore, the cost is $22.5.

Given:

The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.

To find:

The five-number summary.

Solution:

We have,

22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30

Divide the data values on 2 equal parts.

(22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30)

Divide each parentheses in two equal parts.

(22, 23, 23, 24, 24, 24), (25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28), (28, 28, 28, 29, 29, 30)

Now,

Minimum value = 22

[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]

Median = 26

[tex]Q_2=\dfrac{28+28}{2}=28[/tex]

Maximum value = 30

So, the five number summary is 22, 24.5, 26, 28, 30.

Therefore, the correct option is D.
