12 orders in 2 days =
orders per day.???
Answer:
6 orders per day.
Step-by-step explanation:
12 divided by 2 is 6.
This means that in one day they can pack 6 orders.
Answer:
12 orders in 2 days = 6 orders per day
Step-by-step explanation:
In two days, 12 orders were completed. To find the amount of orders per day, we divide the number of orders by the number of days.
12÷2=6
Therefore, 6 orders per day.
A painter uses 1.2 liters of the paint to cover 1m2 of the wall.
How many square meters he can cover with 6.6 liters of paint?
12)/1.2=120/12=10m^2
4.8/1.2=48/12=4m^2
6.6/1.2=66/12=11/2=5.5m^2
this is another way you can do it
1. 12/1.2 times as much paint, so 12/1.2 times as much area.
2. 6.6/1.2 times as much paint, so 6.6/1.2 times as much area.
3. 4.8/1.2 times as much paint, so 4.8/1.2 times as much area.
27. 10) Three and one half dozen equals? *
I
Answer:
I think it is 42.
Because one dozen is equal to 12, and we have 3 dozens, which is equal to 36, then add a half dozen, which is 6, then the total answer will be:
12+12+12+6= 42
I hope this helps.
Answer:
42
Step-by-step explanation:
3.5 dozen is 42
Dozen is 12. 12*3.5= 42
Find the volume of the cylinder 9 cm and 23 cm 
Determine if the product CA is defined. If the product is defined, state its dimensions. Do not calculate the product.
Answer:
The product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
Step-by-step explanation:
Matrix multiplication
To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.
If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).
Matrix A has two rows and three columns (2x3)
Matric C has three rows and two columns (3x2)
If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.
Since both numbers are 2, the product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
What is the value of x?
Answer:
8
Step-by-step explanation:
You have to set up a proportion for this!
Because ABC and PAQ are similar triangles (same angles and PQ || BC), you can assume that all the equivalent sides are proportional!
If you solve the proportion for x:
[tex]\frac{x}{40} =\frac{7}{35}[/tex]
x = 8
Find the product. Enter your final answer as a simplified fraction.

Answer:
I am sorry if I'm wrong, but I got 600 or 36000/60
Step-by-step explanation:
First I looked for the least common denominator,(LCM) it was 60. Then I multiplied the numerator by the number that was multiplied by the denominator to find the new numerator for each fraction.(Example: The denominator was 60, so I looked for what 60 divided by four was, because that was the denominator. It ended up being 15. now I multiplied the numerator, which was 1 by 15 to create the new numerator. Then I did that with the other two fractions.) After all the fractions have the same denominator, you can multiply them. To multiply fractions you multiply all the numerators together and leave the denominator the same. Then I just simplified it. From 36000/60 to 600. Hope this helped :)

Step-by-step explanation
Steve ran for class president against Mandy. Steve received 5 votes for every 3 votes that Mandy received. Mandy received 420 votes. If all the students only voted once?how many students voted in the election? Pls help ASAP!!
Answer:
1120
Step-by-step explanation:
The ratio Steve : Mandy is 5 : 3.
We use a proportion to find the number of votes Steve received.
x = number of votes Steve received.
5/3 = x/420
3x = 5 * 420
x = 5 * 140
x = 700
Steve received 700 votes.
The total number of votes is the sum of the votes Steve receive and Mandy received.
420 + 700 = 1120
A fair coin is tossed three times in succession. The set of equally likely outcomes is {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. Find the probability of getting exactly two heads out of three tosses.

Which expression is equivalent to this polynomial expression?
(2x^5 + 3y^4)(-4x^2 + 9y^4)
Answer:
A. -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
Step-by-step explanation:
Given:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Required:
Find an equivalent polynomial
Solution:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Using distributive property of multiplication
2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)
-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸
There are no like terms to add or combine, therefore:
(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
Answer:
-8x^7 + 18x^5y^5 - 12x^2y^4 + 27y^8

A volunteer is buying 10 blankets for the animal shelter. Shipping the blankets will cost $12 and the volunteer has $75 total to spend. What is the maximum amount the volunteer can spend for each blanket? Write an inequality that would represent the situation and solve the inequality. Show your work to justify your answer.
Answer:
6.3
Step-by-step explanation:
10 blankets with an unidentified price plus 12 for shipping is equal to 75
10x+12=75
minus 12 from both sides
10x=63
divide 10 from both sides
x=6.3
Now, let's prove the answer is true.
10x+12=75
Replace x with 6.3
10(6.3)+12=75
10 times 6.3
63+12=75
75=75
The statement is true.

Calculate the slope of a line that passes through the points (3, -20) and (5,8).
O 6
O4
O 14
O 26
Answer:
Option 3: 14 is the correct answer.
Step-by-step explanation:
Slope is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
(x1,y1) are the coordinates of first point and
(x2,y2) are the coordinates of second point
Given
(x1,y1) = (3, -20) and
(x2,y2) = (5,8)
Putting the values in the formula, we get
[tex]m = \frac{8-(-20)}{5-3}\\m = \frac{8+20}{2}\\m = \frac{28}{2}\\m = 14[/tex]
The slope of line passing through points (3, -20) and (5,8) is 14.
Hence,
Option 3: 14 is the correct answer.

Nancy is checking to determine if the expressions x + 4 + x and 6 + 2 x minus 2 are equivalent. When x = 3, she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x =14. What is the value of the second expression when x = 5, and are the two expressions equivalent? The value of the second expression is 8, so the expressions are not equivalent. The value of the second expression is 14, so the expressions are equivalent. The value of the second expression is 16, so the expressions are equivalent. The value of the second expression is 18, so the expressions are not equivalent.
Answer:
The value of the 2nd expression is 14, so the expressions are equivalent.

Ashton is depositing money into a checking account. After 3 months there is $120 in the account. After 6 months, there is $240 in the account. Determine the constant rate of change of the account.
The constant rate of change of the account is $40 or Increasing by $40 per month.
Step-by-step explanation:
Consider the provided information.
Joanne is depositing money into a bank account. After 3 months there is $120 in the account. After 6 months there is $240 in the account.
Rate of change is known as how one quantity change in relation to other.
The rate of change can be calculated as:
y2-y1/x2-x1
Now use the above formula to calculated the rate of change.
240 - 120/6-3
120/3
40
Hence, the constant rate of change of the account is $40 or Increasing by $40 per month.

Find an equation of the line containing the given pair of points.
(−5,−5) and (4,4)
Answer:
y = x - 9
Step-by-step explanation:
[tex]Slope=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{4-(-5)}{4-(-5)}=\frac{9}{9}=1[/tex]
[tex]y-intercept:y-y_{1}=m(x-x_{1} ) \\y-(-5)=1(x-4)\\y+5=x-4\\[/tex]
Subtract 5 from both sides;
y = x - 9
