Answer:

-Angelina is correct

Explaintion: Jack in incorrect because it seems that he messed up is place order. He might have thought that 1 liter is equal to 100 mililiters instead of 1,000. That way he might have gotten 30+5=35  instead of 5+3=8

Step-by-step explanation:

3000 ML+ 5L

1 milliliter has 0.001 liters in it.

3000ML= 3L

Angelina has 8 lieters of water in the tub now.

Answer:

x = 20

Step-by-step explanation:

Original Equation:

1/2x - 3 = 7

(1/2x can be written as 0.5x)

0.5x - 3 = 7

Add 3 to both sides.

0.5x = 10

Divide both sides by 0.5

x = 20

Answer:

A. y = square root of 2x

We are given the function

y = 2 √x

We are asked for the function that has the same domain as the given function

First, the domain for the given function is this

{ x | x ≥ 0 }

So, any function that has a domain of x that is equal to or greater than 0. Some examples:

f(x) = √x  -  2

f(x) = 5 √x

Answer:

Vanessa, she only needs to buy one ink cartridge according to the question

where Tia has to buy more? I need more info on the question

Step-by-step explanation:

Tia bought less expensive printer.

Given is that Vanessa and Tia buy a printer. Vanessa pays $90 for her printer and each replacement ink cartage cost $25. The equation T = 80 + 20c can be used to find the total cost, T, Tia pays for her printer plus C number of ink cartridges.

Equation that represents the cost for Vanessa's printer is -

V = 90 + 25c

Equation that represents the cost Tia's printer is -

T = 80 + 20c

For {c} = 1, the cost for Vanessa's printer is -

V(1) = $115

For {c} = 1, the cost for Tia's printer is -

T(1) = 80 + 20 = $100

Therefore, Tia bought less expensive printer.

Answer:

Unit rate = $ 30.

Step-by-step explanation:

Unit rate = Total cost ÷ Number of calculators

              = [tex]\frac{150}{5}[/tex]

             = $ 30

Answer:

$30 per calculator

Step-by-step explanation:

To find the unit rate of the calculators, take the total price of calculators and divide it by 5 to get 30.

This method works when finding any unit rate even when it doesn't involve prices.

*Tip* When dividing, write it as a fraction in case the quotient is not a whole number.

Answer:

y+5 = -0.7 (x-1)

Step-by-step explanation:

Answer: 10 tulips, 10 lilies and 23 roses.

Step-by-step explanation:

Let's define the variables:

T = number of tulips that Jennifer bought

L = number of lilies that Jennifer bought

R = number of roses that Jennifer bought

Each tulip costs $0.18

Each lily costs $0.27

Each rose costs $0.55

We know that:

"She bought the same number of tulips as lilies."

T = L

" She bought three more roses than tulips and lilies combined."

R = T + L + 3

"she paid $17.15 in all"

T*$0.18 + L*$0.27 + R*$0.55 = $17.15

Then we have a system of 3 equations:

T = L

R = T + L + 3

T*$0.18 + L*$0.27 + R*$0.55 = $17.15

The first step to solve this is to replace the first equation into the other two, and get:

R = 2*L + 3

L*$0.18 + L*$0.27 + R*$0.55 = $17.15

Now we can replace the first equation into the second:

L*$0.18 + L*$0.27 + (2*L + 3)*$0.55 = $17.15

Now we can solve this for L.

L*($0.18 + $0.27 + 2*$0.55) + 3*$0.55 = $17.15

L*$1.55 + $1.66 = $17.15

L*$1.55 = $17.15 - $1.66 = $15.50

L = $15.50/$1.55 = 10

Then Jennifer bought 10 lilies.

And by the other two equations:

T = L = 10

She bought 10 tulips.

R = L + T + 3 = 10 + 10 + 3 = 23

She bought 23 roses

Answer:

D. -1.5 cm/hour

Step-by-step explanation:

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Using the coordinates of the two points on the line, (0, 18) and (4, 12),

Let,

[tex] (0, 18) = (x_1, y_1) [/tex]

[tex] (4, 12) = (x_2, y_2) [/tex]

Plug the values into the formula for rate of change.

Rate of change = [tex] \frac{12 - 18}{4 - 0} [/tex]

[tex] = \frac{-6}{4} [/tex]

Simplify

[tex] = \frac{-3}{2} = -1.5 [/tex]

Rate of change = -1.5 cm/hour

it should be 4 because 20% is considered vegitarian so 20 * 20% = 4

so it should be 4

Answer:

Step-by-step explanation:

In order to get the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty, we need to calculate the power of the set having four elements. Let the set containing the element be A as shown;

Let set A = {a, b, c, d}

Power of the set P(A) = [tex]2^n[/tex] where:

n is the total number of element in the set. Since we have four elements in the set, n = 4

[tex]P(A) = 2^4\\P(A) = 16[/tex]

This means that the set A have 16 subsets. The subsets of the set are:

{}, {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {b, c, d}. {a, c, d}, {a, b, c, d}.

From all the subsets, it can be seen that intersection of set {a} and {b}, {a} and {c}, {c} and {d} are empty.

Hence the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty is 16
