Answer:

607 miltliters per day

Step-by-step explanation:

Step one:

given data

Kallie drank 12.75 gallons of water in 3 weeks

if she drank the same amount each day, then in one day she will drink

Note----there are 31 days in 3 weeks (7 days make 1 week)

Step two:

Hence in one day she will drink

= total volume of water/number of days

= 12.75/21

=0.607liters per day

or

607 militliters per day

Have a nice day.

None of them is right.

The concept of proportionality in mathematics denotes the linear relationship between two numbers or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount.

Given a table that has work and time spent on that theoretical work has to be proportional to the time such as the Spend time ∝ number of pages read but none of the options match the criteria. Therefore no option is correct for this problem.

Answer:

A

Step-by-step explanation:

The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).

Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.

Answer:

D. it is the graph of y=x translated 7 units up

Step-by-step explanation:

The equation is in the form of y=mx+b, b being the y-intercept of the line. Because b in this case is 7 and the slope is just one, the only transformation was that the graph was shifted 7 units up

Answer: (x+4)(x−9)

Step-by-step explanation:

Answer:

(X - 9) is one factor

(X + 4) is the other factor

Step-by-step explanation:

You can factor polynomials with guess work or with polynomial division

To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.

In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)

I'm pretty sure the answer is 1.

Step-by-step explanation:

Let Maya's age is m.

Sax age is 3 years older than twice Maya's age

Sax age = 2m +3

Zach age = 23 years

We need to find the equation that is used to solve Maya's age. ATQ,

2m + 3 = 23

If we solve,

2m = 23-3

2m = 20

m = 10

Hence, this is the required solution.
