Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.

Answers

Answer:

Inequality: .80x +21 ≤ 82

Answer: 76.25 miles in total

Step-by-step explanation:

Hi,

An inequality to represent this is .80x +21 ≤ 82

(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).

Now we solve...

.80x + 21 ≤ 82

Subtract 21 on both sides...

.80x ≤ 61

Now, divide by .80 on both sides...

x ≤ 76.25

He can drive up to 76.25 miles in total

Hope this helps :)

Nadia's grades on four quizzes were 95, 75, 85, and 95. Find the mean, median, and mode for Nadia's grades. ​

Answers

Answer:

mean: 87.5

median: 80

mode: 95

What is mean? : the sum of a collection of numbers divided by the number of numbers in the collection so for this is:

95+75+85+95= 350 divided by 4 because there's 4 numbers = 87.5 which is the mean

What is median?: The median is the value separating the higher half of a data sample so for this think of crossing each number at the opposite sides: 95 and 95 cancel now your left with 75 an 85 add them up and divide by 2 because there's 2 numbers **for median you are either left with 1 number or 2 if the case is 2 you ADD first then divide by 2 ALWAYS**: 75+85= 160/2= 80 for median

What is mode?: The mode is the value that appears most often in a set of data. So as we know 95 repeats the most

First u want to order the numbers from greatest to least 95,95,85,75
Mean: all numbers added up then divided by the number of numbers u have. So 95+95+85+75= 350 divided by 4 = 87.5
Mean=87.5
Median: the middle number. So after the numbers r ordered from greatest to least take one number off each side until u get to the middle. In this case there are two middle number 95 and 85 so u add them then divide by 2 95+85= 180 divided by 2= 90
Median= 90
Mode: the number that repeats most in the set of numbers. In this case the mode is 95 because there r 2 95s
Mode: 95

A. 1 second
B. 4 seconds

Answers

Answer:

B

Step-by-step explanation:

-t²+4t+5=0

t²-4t-5=0

t²-5t+t-5=0

t(t-5)+1(t-5)=0

(t-5)(t+1)=0

t=5,-1

when t=0,d=5

actual time it it is in air=5-1=4 seconds.

If I did the math correctly, it should be B

explain how to find the slope of a line through two points on a table

Answers

Answer:

you use slope formula m=y2-y1/x2-x1

m=21-11/5-3=15.8

Step-by-step explanation:

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1

                                                                5 is x2 11 is y2

m=y2-y1/x2-x1

m=21-11/5-3=15.8

1675/3890 you are dividing 1675 by 3890 so it equals 0.43059...=0.4 simplified to the first decimal

If you want to divide it in long division then the answer would be, 0.430591

but if you want to simplify the fraction the answer would be

[tex] \frac{335}{778} [/tex]

or if u want it in percent form it would be, 43.059126%

and in decimal form it would be, 0.430591.

B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20
b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10
