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

Answer:

It seems like John is trying to find the mean, or average.

Green is 82

blue is 320

red is 4

Step-by-step explanation:

82 is the score John must get to have the average of 80

320 is the number you must divide by 4 to get 80

Answer:

33

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

Answer: 33

Step-by-step explanation: Write 220% as 220/100

Finding the fraction of a number is same as multiplying the fraction with the number 220/100 of 15

220/100 x 15

Therefore, the answer is 33

Answer:

y = 4/5x

y = 4/5x - 3.2

Step-by-step explanation:

The equation for slope is y=mx+b, the mx stands for the slope which is 4/5x. The b stands for where the line goes through the y axis, in this equation the first line crosses the y axis at the origin (0) and the second one crosses at -3.2, these are also called y-intercepts because they intercept the y axis.

Answer:

Yes, (2, 10) is a solution to this system:

y = 4x + 2

y = x + 8

Step-by-step explanation:

When graphed, the two equations cross at (2,10) making it a solution.

Answer:

Yes

Step-by-step explanation:

If y=4x+2 and y=x+8, then 4x+2=x+8

4x+2=x+8

4x=x+6

3x=6

x=2

Plugging this into the original equation "y=x+8", we obtain the result that y=10.

This means, (2, 10) is a solution  to the system.

Let me know if this helps!

Answer:

Scalene

Step-by-step explanation:

The third angle must be 83 degrees because all interior angles of a triangle add up to 180 degrees. It must be a scalene triangle because all angles are different therefore the lengths are aswell.

Answer:

acute

Answer:

(-10; 60)

Step-by-step explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

(3; -9)

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 -  yes

(18; -3)

-3 = -6 · 18

-3 = -78 - no

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)

Answer:

y=0

Step-by-step explanation:

Simplifying

y + y = 0

Combine like terms: y + y = 2y

2y = 0

Solving

2y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = 0

Simplifying

y = 0

Answer:

The correct answer is,

Answer:

There are 102 children

Step-by-step explanation:

Let us solve the question

∵ There are 272 people in an audience

∴ The total number of people = 272

∵ The ratio of adults to children is 5: 3

→ Find the sum of the two parts of the ratio

∴ The sum of the parts of the ratio = 5 + 3 = 8

→ By using the ratio method

→  Adults:  Children:  People

→  5        :   3            :  8

→  A        :   C           :  272

→ By using the cross multiplication

∵ C × 8 = 3 × 272

∴ 8C = 816

→ Divide both sides by 8

∴ C = 102

∵ C represents the number of children

∴ There are 102 children

Answer: Variable: y= Number of sour straws.

Inequality: 7.50+1.50y ≤ 15

Solution: y ≤ 5

Step-by-step explanation:

Let  y= Number of sour straws.

Cost for nachos = $7.50

Cost per sour straw = $1.50

Total cost = 7.50+1.50y

Money he has $15

Total cost must be less than orequal to the money he has.

So required inequality: 7.50+1.50y ≤ 15

Subtract 7.50 from both sides

[tex]1.5y\leq 7.5\\\\\Rightarrow\ y\leq\dfrac{7.5}{1.5}\\\\\Rightarrow\ y\leq 5[/tex]

He can buy at most 5 sour straws.

Answer: Eva's dog actually gained 3/8 pounds ( 0.375pounds)

Step-by-step explanation:

Step 1

Given that

old weight = 1 7/8  pounds

New weight = 2 1/4 pounds

weight gained = New weight - Old weight

Step 2

 weight gained = New weight - Old weight

                  2 1/4  pounds - 1 7/8 pounds

      2.25 pounds - 1.875 pounds

         0.375pounds = 3/8 pounds
