Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.

Answers

Answer 1

Answer:

9.55 minutes

Step-by-step explanation:

x hours to go to the river

0.25-x hours to come back, since 15 minutes is 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

those two are equal

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

9.55 minutes

Find the x-intercept of the graph of the equation =−.+y equals negative , 2.65 , x plus 25.
What does the x-intercept mean in terms of the situation?

Answers

Answer:

Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

Step-by-step explanation:

If x oranges were sold on Thursday, what is two times that? Well, 2*x is the same thing as 2x. When a variable and a number a put together, that means it is being multiplied. So, on Thursday x oranges were sold, and on Friday twice as much as that were sold. So, at the bottom, in the red part wold be x and 2x. The blue bar is the total number of oranges sold, which is 108.

108 is the total amount. That’s why it’s the top biggest box. The two smaller boxes make up the total of 108. X is the amount she made on Thursday. 2x is the amount she made of Friday.

A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?
A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10

Answers

B is the correct answer

Answer:

B. y=-9x-10

Step-by-step explanation:

The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.

Can someone please give me an answer.

Answers

It is not A. It’s B!
The reason it’s B is because when you look at the table, the y- intercept (or where it’s at when it’s at 0) is -75.
So you know it’s
Y= (something) -75
When you look at the rest of the table you can see that for every five it’s going up on the left side, it’s going up 25 on the right side.
If you divide 25 by 5 to figure out how much it is going up per 1 time instead of 5, you will get 5. You have to add X to that because that is the slope or how much you are going up by.
That means your equation is...
y=5x-75, or B!
Hopefully that helps you!

The answer is y=5x-75 or B

The total amount all friends paid is 5d + 5(2.5d) + 5(d - 4).

The total amount for the meal is 5(d - 4).

The total amount each friend paid is d + 2.5d + (d - 4).

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of friends = 5

Entrance fee = $d

Booklet ticket = $2.5d

Meal ticket = $d - 4

Now,

The total amount all friends paid.

= 5 x (d + 2.5d + (d - 4) )

= 5d + 5(2.5d) + 5(d - 4)

The total amount for the meal.

= 5 x (d - 4)

= 5(d - 4)

The total amount each friend paid.

= d + 2.5d + (d - 4)

Thus,

All the expressions given are correct.
