antoine went on vacation to las vegas. his room cost 115.62 each night. his flight there cost $45.70 and his flight. was32.49. he averaged $15.00 per day on food. on the first dat antoine won$75.00 and on the last day he lost $25. if he stayed for 3 nights and 4 days, how much did the entire trip ( including airfare, food , hotel and wining ) cost him ?

Answers

Hotel

He stayed 3 nights, so $115.62 × 3 = $346.86

Airfare

$45.70 + $32.49 = $78.19

Food

He averaged $15 a day, and he stayed 4 days.

$15 × 4 = $60

Winnings

He won $75 but lost $25

$75 - $25 = $50 won.

Adding up all the expenses and winnings, we find that he paid $435.05 for his trip.

Temperature changes throughout the hours of a day. Early in the morning, temperature increases slowly. At noon, the temperature rises sharply. During the afternoon, the temperature stays the same for several hours. As night falls, the temperature decreases slightly. Choose the graph that best represents this situation,

Answers

Final answer:

A line graph would best represent the temperature changes throughout the hours of a day, showing a slow increase in the morning, a sharp rise at noon, a plateau in the afternoon, and a slight decrease at night.

Explanation:

The best graph to represent the temperature changes throughout the hours of a day would be a line graph. The graph should show a slow increase in temperature early in the morning, a sharp rise at noon, a plateau during the afternoon, and a slight decrease as night falls. This pattern follows the circadian rhythm, where temperature rises throughout the waking day, peaks in the afternoon, and falls during sleep.

Step-by-step explanation:

the answer is D

Consider the function represented by the equation 6c = 2p – 10. Write the equation in function notation, where c is the independent variable.

Answers

we have

$6c = 2p - 10$

If c is the independent variable

then

p is the dependent variable

clear variable p

$6c = 2p - 10$

Divide by $2$ both sides

$3c = p - 5$

Adds $5$ both sides

$3c+5 = p - 5 +5$

$p=3c+5$

Write the equation in function notation

$f(c)=3c+5$

therefore

the answer is

the equation in function notation is equal to $f(c)=3c+5$

f(c)=3c+5 is the right answer

In one day, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda. Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk. Marian consumes 510 calories by drinking 3 servings of milk and 1 soda. Using matrices to solve, how many calories are in 1 serving of milk?A. 90
B. 110
C. 130
D. 180

Answers

Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories

How to solve Linear Programming problems?

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

Thus, for Joe, equation to show amount of calories is;;

2x + y + z = 530 -----(1)

For Darius, equation to show amount of calories is; ;

x + 2y = 370 ------(2)

For Marian, equation to show amount of calories is;

3x + z = 510 ------(3)

Using matrix calculator online to calculate this 3 equations, we have;

x = 110 calories.

Answer:

the answer is B on ed2020

Step-by-step explanation:

for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.

so you have soda = 180 cal and juice = 130 cal

if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct

For the first question the equation would be 200 + 50x

The second equation should be
200 + 50(1) = 250
