Answer:

7.5 miles per gallon

Step-by-step explanation:

Given that:

8 gallons of gasoline traveled 340 miles

After being worked on by the mechanic :

7 gallons travels 350 miles

How many more miles per gallon did Darnell's car travel after the mechanic worked on it?

Obtain the unit mile traveled per gallon before and after the mechanic worked on the car :

Miles per gallon before being worked on by mechanic :

340 miles / 8 gallons = 42.5 miles per gallon

Miles per gallon after being worked on by mechanic :

350 miles / 7 gallons = 50 miles per gallon

(50 - 42.5) = 7.5 miles per gallon

Hence, vehicle moved 7.5 more miles per gallon after bwing worked on by mechanic.

Answer:

the answer is probably 3/5 since its the starting one so it will be how t started

Step-by-step explanation:

Answer:3:5

Step-by-step explanation:well when you divide 6/10 it equals 3/5.when you divide 9/15 it equals 3/5 and so on.

Answer:

Step-by-step explanation:

a. RG=36 since RG=2(RT)

b.

4x+12=10x-15 Since RG and HI are equivalent

12=6x-15 Subtract 4x from both sides

27=6x Add 15 to both sides

4.5=x Divide by 6 on both sides

to double check:

4(4.5)+12=30

10(4.5)-15= 30

so x=4.5

Answer:

1/8

Step-by-step explanation:

Rate is the change of a quantity per unit time

We are told Sarge completed 1/10 of his report in 4/5 of an hour.

We are going to equate the rate at 4/5hour to that of 1hour to get how much of the report Sarge will complete in 1 hour

(1/10)/x=(4/5)/1

0.10/x=0.8

Make x subject of the formula we have

X=1/8

Hence 1/8 of the report needed to be completed

Answer:

Step-by-step explanation:

x + 7 ≤ -9 subtract 7 from both sides

x≤-16  this is your answer

If you're plotting it will be (-∞,-16]

Answer:

Step-by-step explanation:

For this equation, all it is asking is to replace the unknown value with a number that completes the equation. However, the number must make the equation valid. Here is a few examples that could be a valid solution to this problem:

1. -55 + 7 < -9

(you don't need to solve this equation to tell that it's less than negative nine.)

2. 22 + (-98) + 7 < -9

(this is more complicated, but you can still tell that the sum is less than negative nine.)

So, basicly all that you have to do is replace the missing value with a number that gives the eqquation a sum less than negative nine. Hope this helped!!! :)

Answer:

Because angle 5 and angle 6 equal each other, it would mean that 4 and 7 equal each other. The sum of angles 4 and 5 is 180 because they are on the same line, intersected by another line. This means that they are supplementary angles. Since angles 5 and 6 equal each other, the other part of the the supplementary angle on both sides must equal each other. For example, if angles 5 and 6 equaled 60 degrees, the counterparts on the supplementary angle on both sides would have to be 120 to get to final sum of 180. This shows how angle 4 and 7 have to equal each other if 5 and 6 also equal other. Hope this helped! If its still confusing leave a comment and ill explain it in a different way. Good luck!

The total cost of chocolate sprinkles is $800

This is an implementation of the numeral system that shows the value of each digit in a number using their positions

Given that, Chocolate sprinkles cost as much per pound as sugar.

From the complete question, we have the following parameters:

Unit rate = $8.00

Total pounds = 100

Total cost of chocolate sprinkles

So, the total cost of chocolate sprinkles is calculated using the following formula;

Unit = Total / Pounds

This gives

$8.00 = Total / 100

Total = $800

Hence, the total cost of chocolate sprinkles is $800

Step-by-step explanation:

The coordinate is in the form (x,y) so the x-coordinate would be 6

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1 , thus

y = x + c ← is the partial equation

To find c substitute (1, 0) into the partial equation

0 = 1 + c ⇒ c = 0 - 1 = - 1

y = x - 1 ← equation of line

Answer:

Step-by-step explanation:

Step one:

Given data

AT&T’s plan

monthly charge= $19.99

additional charge per minute= $0.35

let the number of minutes be x

let the total charges be

y=0.35x+19.99----------1

Verizon’s plan

monthly charge= $34.99

additional charge per minute= $0.3

let the number of minutes be x

let the total charges be

y=0.3x+34.99----------2

Step two:

equating the two equations above we have

0.35x+19.99=0.3x+34.99

collect like terms

0.35x-0.3x=34.99-19.99

0.05x=15

divide both sides by 0.05

x=15/0.05

x=300

For the two plans to cost the same, it will take 300 minutes

300 Minutes

Answer:

50 son las veses que me pasie, y el 15 son otras actividades que realice

Step-by-step explanation:

La r en ese lugar esta multiplicando al 50

Answer:

.50 means cost per ride and 15 ticket cost

Step-by-step explanation:

say there are 4 ride you want to go on, lets substitute r, rides, with 4

.50(4) + 15

.50 times 4 is 2

so now we have 2 + 15

2 + 15 = 17

so you have spent $17 at the carnival.

Answer:

7.0 m/s

Step-by-step explanation:

Use the formula vf^2 = vo^2 + 2*a*d

since the rock is dropped, its initial velocity is zero:

vf^2 = 2*9.8*2.5 = 49

vf = 7.0 m/s

B. 7.0 m/s

[tex]f(x) = {x}^{2} - x - 6 [/tex]

[tex]f(x) = (x - 3)(x + 2)[/tex]

[tex]0 = (x - 3)(x + 2)[/tex]

_________________________________

Hint :

[tex]a \times b = 0[/tex]

[tex]a = 0 \: \: \: or \: \: \: b = 0[/tex]

_________________________________

Thus ;

[tex] x - 3 = 0[/tex]

Add sides 3

[tex]x - 3 + 3 = 0 + 3[/tex]

[tex]x = 3[/tex]

Or

[tex]x + 2 = 0[/tex]

Subtract sides 2

[tex]x + 2 - 2 = 0 - 2[/tex]

[tex]x = - 2[/tex]

Thus the x-intercepts are (( - 2 )) and (( 3 )) .
