Answer:
1,100 miles traveled in 2 hours, 3,300 miles in 6 hours
Step-by-step explanation:
if the plane is moving at a constant speed, to find the miles per hour divide the distance traveled over the time (1650/3). this would get you 550 miles per hour. So, to get the distances at the other times multiply the times by the speed to get distance traveled. (2*550) and (6*550)

Marcellus is making a deposit that will leave him with a balance of $381. He noticed that if he added $54 to the amount he started with in his account and then tripled the sum, he would get the new amount. How much did Marcellus originally have in his account? Which equation represents the situation?
Answers
Answer:
Step-by-step explanation:
Let the initial money deposited in the account be x:
If he added $54 to the amount he started with in his account, the expression will become:
x+54
If the sum is tripled, we will have:
3(x+54)
Since the balance an-mount is $381, the final equation will give:
3(x+54) = 381
The equation that represents the situation is 3(x+54) = 381
Next is to calculate x:
3(x+54) = 381
open the parenthesis
3x+162 = 381
3x = 381 - 162
3x = 219
x = 219/3
x = 73
Hence the original amount in his account is $73

Let f(x) = 12 over the quantity of 4 x + 2 . Find f(−1). (1 point) a −6b −2c 2d 6
Answers
Answer:
f(-1) = -6
Step-by-step explanation:
f(x) = 12 / ( 4x+2)
Let x = -1
f(-1) = 12 / ( 4*-1+2)
= 12 / (-4+2)
= 12 / -2

Claire and Richard are both artists. Claire uses the polynomial 50x^2+250 to decide how much to charge.Richard uses the polynomial 49x^2+350 to charge how much to charge for his painting.In each polynomial x is the height of the paintings feet. To the nearest tenth what height will both Claire and Richard charge for the same amount for a painting?
Answers
Answer:
The height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.
Step-by-step explanation:
The polynomial expression representing the charge for Claire's paintings is:
C = 50x² + 250
The polynomial expression representing the charge for Richard's paintings is:
R = 49x² + 350
Here x represents the height of the paintings feet.
Now compute the value of x such that both Claire and Richard charge the same amount as follows:
C = R
50x² + 250 = 49x² + 350
50x² - 49x² = 350 - 250
x² = 100
x = 100
Thus, the height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.

The equation is y =
Answers
Answer:
The equation is y = 3.2x + 15
Step-by-step explanation:
We know that the beginning height is 15 cm, so that will be our y-intercept, since we started with that. We also need the slope, which is the rate of change. The rate of change is 3.2 cm per week, so the slope is 3.2. This makes the equation y = 3.2x + 15. I hope this helps, and I hope it's not wrong, which I don't think it is.

Rosa bought a storage container in the shape of a cube to store clothes. The storage container has a volume of 950 cubic inches. What is the
length of one side of the storage container? Estimate the length to the nearest integer.
inches
Answers
Answer:
10 in
Step-by-step explanation:
The length, height and width of a cube are always equal. Therefore, the length of one side of the storage container can be any of the side length of the cube.
Volume of cube is given as a³. Where, a = length of one of the sides
Given that the storage container has a volume of 950 in³, side length of one side is:
[tex] 950 = a^3 [/tex]
[tex] \sqrt[3]{950} = \sqrt[3]{a^3} [/tex]
[tex] \sqrt[3]{950} = a [/tex]
[tex] 10 = a [/tex] (nearest integer)
Length of one side = 10 in
