At a book fair there were 45 fiction books sold. If the ratio of fiction books sold to non-fiction book sold was 5 : 4, how many books were sold total?

=======================================================

Explanation:

Slope is the same as the rate of change for any linear function. We ignore the y intercepts.

The slopes of the four equations, A through D, are: 7/6, 7/5, 6/5, and 5/4

This is because each equation is in y = mx+b form with m as the slope.

Convert each fractional slope into decimal form

We see that 7/5 produces the largest decimal, so 7/5 is the largest fraction of the four slopes.

Therefore equation y = (7/5)x+7/5 has the greatest rate of change.

Answer:

the answer to the question is -5/3

Answer:

0.4miles.

Step-by-step explanation:

The total distance to run for the marathon = 5.2 miles

Susan is currently running 4.8 miles in 22 minutes.

How much further does she need to run in the 22 minutes to complete the marathon and reach her goal?

= 5.2 - 4.8

= 0.4 miles.

Answer:

Step-by-step explanation:

Probability is the ratio of the required outcome to the total possible outcome

Total outcome = 75

Number of times target was hit (expected outcome) = 41

Pr(she will hit target)= 41/75

Next is to state in percent and u do that by multiplying the resulting fraction by 100

41/75 i n percent.

41/75×100

= 4100/75

= 54.67%

Hence the answer in percentage is 54.67%

Explanation:

For every problem, plug in the number where the variable is.

For example:

Evaluate the following expression by substituting 8 for x.

x + 9

You would take the x and turn it into 8, then you would do 8 + 9.

Answer:

1)  

a= 17

b= 7

c= 56

d= 4

e= 29

f= 10

g= 18

h= 4

2)

a= -1

b= 2/3

c= -4/3

d= -5/3

e= -2

f= -8/3

g= -14/9

h= -17/9

3)

a= 1/2

b= 5/6

c= 1/6

d= -1/3

e= 1/3

f= 5/12

g= 7/18

h= 0.75

Step-by-step explanation:

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

Answer:

B

Step-by-step explanation:

Answer:

a. -7

b. -25

c. 27

d. 15

Step-by-step explanation:

The solution of expression is a) 13 + (-20) = -7

b) (-14) + (-11) = -25

c) 18 - (-9) = 27

d) (-21) - (-36) = 15

a) 13 + (-20) = -7

To add a positive number and a negative number, we subtract the absolute values and use the sign of the number with the greater absolute value.

b) (-14) + (-11) = -25

When adding two negative numbers, we simply add their absolute values and retain the negative sign.

c) 18 - (-9) = 27

Subtracting a negative number is equivalent to adding its positive value. Therefore, 18 - (-9) becomes 18 + 9, which equals 27.

d) (-21) - (-36) = 15

Similar to the previous example, subtracting a negative number is equivalent to adding its positive value. (-21) - (-36) becomes (-21) + 36, which equals 15.

[tex]\boxed{x=-25}[/tex]

Step-by-step explanation:

[tex]\frac{2}{7} (x+4)=-6[/tex]

→ Multiply everything by 7 to get rid of the fraction

[tex]2(x+4)=-42[/tex]

→ Expand the bracket

[tex]2x+8=-42[/tex]

→ Minus 8 from both sides to isolate 2x

[tex]2x=-50[/tex]

→ Divide both sides by 2 to isolate x

Answer:

[tex]r=\sqrt[3]{\frac{3v}{\pi h} }[/tex]

Step-by-step explanation:

The equation is  v=1/3πr³h

Multiply both sides of equation by 3 to get

3v=πr³h

Divide both sides of the equation by πh to get

3v/πh = r³

Apply cube root on both sides of the equation as;

[tex]\sqrt[3]{\frac{3v}{pih} } =r[/tex]

Answer:

The Answer is 20^13

Step-by-step explanation:

to solve this equation all you have to do really is look at the exponents

anytime your dividing an exponent its subtraction so if the top is 20^k and ur looking for k look at the other numbers we have on the bottom of the fraction

20^4 and we have the answer as 20^9 , all we have to do it add the exponents 4 and 9 to get 13

Answer:

Step-by-step explanation:

I'm still not exactly sure what the question really is, but the level suggests that it is

y = (6/7)x + 5

Any line that is parallel to this line has a slope of 6/7

Any line that is perpendicular to this line is a little more complicated.

slope of given line * slope of perpendicular line = - 1

6/7 * perpendicular slope = - 1  

Multiply by 7

6*perpendicular slope = - 7

Divide by 6

perpendicular slope = - 7/6
