Jeremy wants to give a 20% gratuity to his cab driver. His fare is $35.50. What is the total amount he will pay the driver?


A. $7.10

B. $17.75

C. $42.60

D. $63.90

Answer:

b)-9,2

Step-by-step explanation:

x^2+7x-18=0

x^2+9x-2x-18=0

x(x+9)-2(x+9)=0

(x+9)(x-2)=0

therefore

x=-9

x=2

Answer:

m = 1/7

Step-by-step explanation:

(0 - 1)/(-7 - 0)

-1/-7 = 1/7

Answer:

x = 23

y = 7

z = 11

Step-by-step explanation:

Since ∆PRS ≅ ∆CFH, therefore,

m<R = m<F

13y - 1 = 90° (substitution)

Add 1 to both sides

13y - 1 + 1 = 90 + 1

13y = 91

Divide both sides by 13

13y/13 = 91/13

y = 7

Since ∆PRS ≅ ∆CFH, therefore,

PS = CH

2x - 7 = 39 (substitution)

Add 7 to both sides

2x - 7 + 7 = 39 + 7

2x = 46

Divide both sides by 2

2x/2 = 46/2

x = 23

Since ∆PRS ≅ ∆CFH, therefore,

m<S = m<H

Find m<S

m<S = 180 - (m<P + m<R) (sum of ∆)

m<S = 180 - (28 + (13y - 1)) (substitution)

Plug in the value of y

m<S = 180 - (28 + (13)(7) - 1))

m<S = 180 - (28 + 91 - 1)

m<S = 180 - 118

m<S = 62°

Therefore, since m<S = m<H,

62° = 6z - 4 (substitution)

Add 4 to both sides

62 + 4 = 6z - 4 + 4

66 = 6z

Divide both sides by 6

66/6 = 6z/6

11 = z

The values of x, y, and z are;

x = 23

x = 23y = 7

x = 23y = 7z = 11

We are told that triangle PRS is congruent to triangle CFH.

Since both triangles are congruent, by inspection we can see that;

m<R = m<F

m<F is a right angle = 90°. Thus;

13y - 1 = 90

13y = 90 + 1

13y = 91

y = 91/13

y = 7

Also by inspection;

PS = CH

2x - 7 = 39

2x = 39 + 7

2x = 46

x = 46/2

x = 23

Since m<R is 90°, then;

m<S = 180 - (90 + 28)

m<S = 62°

By inspection;

m<S = m<H

Thus;

6z - 4 = 62

6z = 66

z = 66/6

z = 11

Answer:

Step-by-step explanation:

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

Explanation:

We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.

Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.

Answer:

The average rate of change is 0

Step-by-step explanation:

You don't really have to do any math for this problem. The vertex lies at the center of [-2,11] so it means that the slope going across the interval line (x=1) is 0. (i used desmos to graph it)

j/2+3

Step-by-step explanation:

Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.

Then it says that George is 3 years older, so that would be addition.

Therefore, it would be:

x/2+3

Answer:

4

Step-by-step explanation:

We can see from the two marked points the coordinates are: (2, 8) and (4, 16)

That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.

Therefore slope = rise/run = 8/2 = 4.

Answer:

w = -3

Step-by-step explanation:

-23 = 13w + 2w + 22

Combine like terms (add 13w and 2w and subtract 22 from both sides)

-45 = 15w

Divide both sides by 15

w = -3

Answer:

v = 60 yards

Step-by-step explanation:

In the similar triangles, their corresponding sides are proportional which means they have equal ratios

In triangles IHG and FHJ

∵ Δ IHG ≈ FHJ

∵ Side IH is corresponding to side FH

∵ Side HG is corresponding to side HJ

∵ Side IG is corresponding to side FJ

→ Their ratios are equal

∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]

∵ IH = 54 yards and FH = 72 yards

∵ IG = v and FJ = 80 yards

→ Substitute them in the first and last ratios above

∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]

→ By using cross multiplication

∴ v × 72 = 80 × 54

∴ 72v = 4320

→ Divide both sides by 72

∴ v = 60 yards

Answer:

She rode 17.4 miles in 1 hour

Step-by-step explanation:

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?

Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?

The quotient is the average speed and this is calculated as:

Speed = Distance(miles)/Time(hours)

Where speed = quotient

Distance = Dividend

Time = Divisor

Speed = 60.9 miles/3.5 hours

= 17.4 miles/hour

Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!

If :

3.5 hours = 60.9 miles

1 hour = x miles

Cross Multiply =

3.5x = 60.9 miles

x = 60.9/3.5

x = 17.4 miles

Hence, she rode 17.4 miles in 1 hour
