A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 40 pounds
and each large box of paper weighs 70 pounds. A total of 20 boxes of paper were
shipped weighing 1220 pounds altogether. Write a system of equations that could be
used to determine the number of small boxes shipped and the number of large boxes
shipped. Define the variables that you use to write the system.

If f (x) = one-ninth x minus 2, what is f>1(x)
Answers
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
Answer:
Answer: f-1(x) = 9x + 18.

what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6
Answers
Step-by-step explanation:
(1/3a^2-4b)^6 for such an expansion the general term is
[tex]tr + 1 = \binom{6}{r} \times ( \frac{1}{3} {a}^{2} ) ^{6 - r} \times (4b)^{r} [/tex]
we want b^2 so r=2
so the formula transform to:
C6,2*(1/3)^4*a^8*4^2*b^2 so the coefficient of a^8b^2 is
(6*5/2*1)*(1/3^4)*4^2=
6*5*4*4/2*3*3*3*3=16*5/27=80/27

EF ≈ 1.98
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{EF}{FD}[/tex] = [tex]\frac{EF}{4.5 }[/tex] ( multiply both sides by 4.5 )
4.5 × sin26° = EF
4.5 × 0.44 = EF , that is
EF ≈ 1.98 ( to 2 dec. places )
A deluxe bakery sells a cookie for $2.38, a brownie for $3.07 and a cake for $14.87. On Wednesday they sold 13 cookies, 4 brownies and 4 cakes. The cost in ingredients for each cookie is $1.7, for each brownie is $1.91 and for each cake is $5.83. How much profit did they make on Wednesday?
Answers
Answer:
$ 49.64
Step-by-step explanation:
Selling price of cookie on Wednesday = 13 × 2.38 = $30.94
Selling price for brownie on Wednesday = 4 × 3.07 = $ 12.28
Selling price for cakes on Wednesday = 4 × 14.87 = $ 59.48
Cost price for cookie = 13 × 1.7 = $ 22.1
Cost price for brownie = 4 × 1.91 = $ 7.64
Cost price for cakes = 4 × 5.83 =$ 23.32
Total profit for Wednesday= Total selling price - total cost price
That is;
(30.94 + 12.28 + 59.48) - (22.1 + 7.64 +23.32) = $ 49.64

function: (1, 98), (2, 98), (3, 2), (4, -86)not a function: (1, 98), (2, 98), (3, 2), (3, -86)Step-by-step explanation:
A relation that is a function has unique x-values. A relation that is not a function has at least one x-value that is repeated. The y-values do not need to be unique in either case, except that a repeat of the same (x, y) pair does not disqualify a relation from being a function.
In the table shown above, the non-function has the x-value of 3 repeated with different y-values.

What is x
Answers
Answer:
x = 109°
Step-by-step explanation:
Angle x lies outside of line d, and is also positioned just on the side of line a that is opposite to the side of line a occupied by angle 109°.
Therefore, angle x and the angle measure of 109° are alternate exterior angles.
Alternate exterior angles are congruent.
x = 109°.

90 tens
Step-by-step explanation:
900 = 10x
Variable x refers to how many 10's are needed to equal 900
To solve for this, divide both sides of the equation by 10
900 ÷ 10 = 10x ÷ 10
90 = 1x
90 = x
It will take 90 tens to equal 900

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Answers
Sine he runs 2 miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.
