Answer:

21 glasses of milk

Step-by-step explanation:

7 days in 1 week

3 glasses of milk each day

7 * 3 = 21 glasses

Answer:

21

Step-by-step explanation:

3 glasses of milk every day times the days in a week, so 7 equals 21

7x3= 21

Answer:

x=  −1 /2   or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

Step 1: Subtract 4 from both sides.

2x^2−7x−4 =4 −4

2x^2−7x−4=0

Step 2: Factor left side of equation.

(2x+1)(x−4)=0

Step 3: Set factors equal to 0.

2x+1=0 or x−4=0

x=  −1 /2   or x=4

(BTW, there are supposed to be two answers, it's factoring)

Answer:

m= 4

Step-by-step explanation:

3m +2n= 16 -----(1)

m -2n= 0 -----(2)

From (2):

m= 2n -----(3) (+2n on both sides)

subst. (3) into (1):

3(2n) +2n= 16

6n +2n= 16

8n= 16 (simplify)

n= 16 ÷8

n= 2

subst. n=2 into (3):

m= 2(2)

m= 4

Answer:

None

Step-by-step explanation:

In this case we must pass everything to the same unit of measure, we know that the total is 5 liters of soft drink and that each plastic cup has a capacity of 250 cubic meters.

We know that 1 liter is equivalent to 0.001 cubic meters, therefore we will pass the cubic meters of the plastic cup to liters, like this:

250 m ^ 3 * 1 L / 0.001 m ^ 3 = 250,000 L

Therefore we realize that the glass has a very large capacity, which suggests that there is an error in the statement, maybe it is not a cubic meter but a cubic centimeter, but as it is, it cannot serve any plastic cup because the capacity of this cup is very large with respect to the total amount of soft drink.

Answer:

Debit Salaries Expense $480 and credit Salaries Payable $480

Step-by-step explanation:

Firstly, we will need to calculate the salary expense of the company on these two employees.

Mathematically, that would be

2 employees * 2 days * 120/employee/day = 2 * 2 * 120 = $480

Thus, the month-end adjusting entry to record the salaries earned but unpaid is that salaries expense will be debited $480 and salaries payable will be credited $480

Answer:

-3/2

Step-by-step explanation:

pick any 2 points on the graph. I chose (80,10) and (60, 40) because they are easy to identify.

40- 10 = 30

60-80 = -20

slope = -30/20 or -3.2

Answer:

The answer would be 116

Step-by-step explanation:

The angles X and Z would be equal at 32 so multiply them by 2 and you would get 64 subtract 64 from 180 and you would get 116

Answer:

Y =116

Step-by-step explanation:

We know that angle Z = angle X since they are base angles  and  the sides are the same length

The sum of the angles of a triangle are 180

X+Y+Z = 180

32+ Y + 32 = 180

64+Y=180

Y = 180-64

Y =116

you have two walls that are  10 by 7.5 so 75 feet ^2 in area each

you have another two walls that are 14 by 7.5  so 105 feet^ 2 each

so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy

for the ceiling you do the same, the area is 140 and you only need one coat

Answer: A

Step-by-step explanation:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

The possible values of y are [-infinity,4], so the answer is A

Answer:

A ≈ 21.16m²

Step-by-step explanation:

Answer:

21.16 m^2

Step-by-step explanation:

If the perimeter is 18.4 m, then the length of a side is 18.4 m / 4, or 4.6 m.

Then the area of the square is (4.6 m)^2, or 21.16 m^2

Answer:

Area=57.75 m squared

Step-by-step explanation:

Area= L x W

Area= 11 x 5.25

Area=57.75 or 57 3/4

Answer:

S: 1st quadrant

K:2nd quadrant

W:3rd quadrant

Answer:

Step-by-step explanation:

1, sec theta  * sin theta = 1/cos * sin = sin/cos =tan theta

2. cosec theta * cos theta = 1/ sin * cos = cos/sin = cot theta

3, tan theta * cosec theta =sin/cos * 1/sin = 1/cos

4, cot theta * sec theta = cos /sin * 1/cos= 1/sin

5, 1 - cos^2 theta = sin ^2 theta

6, sec^2 theta - 1 =tan ^2 theta

7 , cosec^2 theta - cot^2 theta = 1

8, 1 - sin^2 theta = cos^2

Answer:

False

Step-by-step explanation:

A checkout clerk at a department store is expected to complete 16 transactions every hour

I.e 16 transactions in 60 minutes

So if it's 6 transactions, let's check to know if the minutes Tally.

16 = 60

6 = (6*60)16

6 = 22.5 minutes

But in the statement it was 20 minutes, so the answer is false.

Answer:

Sophia's monthly spent on food is $300 while she wants to spend $245.

As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month

Step-by-step explanation:

Net income of Sophia = $2,450

% of money she wants to spend on food = 10% of Net income of Sophia

thus,

Amount of money she wants to spend on food in $

           =  10% of $2,450

           = 10/100 * $2,450 = $245

Hence, Sophia wants to spend $245 in a month on food.

__________________________

it is given that last week she spent $75 on food

thus, weekly spent on food = $75

as there are 4 weeks in a months

money spent by her in 4 weeks = $75* 4 = $300

Thus, her monthly spent on food is $300 while she wants to spend $245.

As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month

this is true because khan academy

The missing factor of the given equation is 9y.

The factors of the expressions are the simplified expression which when multiplied results in the original expression.

Divide 18y³ by 2y² to determine the missing factor.

G=18y³/2y²

Express the numerator and denominator in the factored form and simplify.

G=(2·3·3·y·y·y)/(2·y·y)

G=3·3·y

G=9y

So, the missing factor of the given equation is 9y.
