System of equations, please help.
Answer:
3.75*A + 2.50*D = 35
A + D = 12
A = 12 - D
3.75*(12-D) +2.5*D= 35
45 - 3.75D + 2.5D = 35
45 - 1.25D = 35 |-35
10 - 1.25D = 0 |+1.25D
10 = 1.25D | /1.25
8 = D
A+D=12
A+8=12 |-8
A=4

The length of an original drawing is 6 inches and the scaled drawing is 9 inches. What is the scale factor as a percent?
Answer:
2/2 I'm not sure for that but its base on answer key
Answer:
[tex]66 \frac{2}{3} \%[/tex]
Step-by-step explanation:
[tex]scale \: factor = \frac{scaled \: drawing}{original \: drawing} [/tex]
[tex]∴scale \: factor = \frac{6}{9} [/tex]
Simplify the fraction by dividing both the numerator and denominator by 3:
[tex]scale \: factor = \frac{2}{3} [/tex]
As a percentage, scale factor
[tex] = \frac{2}{3} \times 100\%[/tex]
[tex] = 66 \frac{2}{3} \%[/tex]

Tracey paid $374.25 for a new iPad. What was the original cost if the iPad was on sale for 25% off
Answer:
$467.8125
Step-by-step explanation:
Percentage increase = 25% × 374.25
New value = 374.25 + Percentage increase
New value =
374.25 + Percentage increase =
374.25 + (25% × 374.25) =
374.25 + 25% × 374.25 =
(1 + 25%) × 374.25 =
(100% + 25%) × 374.25 =
125% × 374.25 =
125 ÷ 100 × 374.25 =
125 × 374.25 ÷ 100 =
46,781.25 ÷ 100 =
467.8125 ≈
467.81

Coffee is sold in two different-sized canisters. The smaller canister has a diameter of 9 cm and a height of 12 cm. The larger canister is double the size of the small canister. Calculate the volume and surface area of each canister and compare the results of doubling the dimensions.
Answer:
Step-by-step explanation:
Smaller Canister:
Height, h = 12cm
Diameter = 9cm
Radius, r = 4.5 cm
[tex]Volume = \pi r^2h\\[/tex]
[tex]=\pi \times 4.5^2 \times 12\\\\=243 \pi \ cm^3[/tex]
[tex]Surface \ area = 2 \pi r(r + h)\\[/tex]
[tex]=2 \times \pi \times 4.5 ( 4.5 + 12)\\\\= \pi \times 9(16.5)\\\\=148.5 \ cm^2[/tex]
Larger Canister:
Measures double the smaller canister, that is
height, H = 24 cm
Diameter = 18cm
Radius, R = 9cm
[tex]Volume = \pi R^2 H\\[/tex]
[tex]= \pi \times 9^2 \times 24\\\\= \pi \times 81 \times 24 \\\\= 1944 \pi[/tex]
[tex]Surface \ area = 2 \pi R(R+ H)[/tex]
[tex]= \pi \times 2 \times 9 ( 9 + 24) \\\\= \pi \times 18(33)\\\\=594 \pi \ cm^2[/tex]
Comparing results :
[tex]Volume_{small} = \pi r^2 h\\\\Volume_{large} = \pi R^2 H = \pi(2r)^2(2h) = \pi(4r^2)(2h)= 8 \pi r^2h = 8 \times volume_{small}[/tex]
Therefore, volume of larger canister is 8 times the volume of smaller canister.
[tex]Surface\ area _{larger} = 2 \pi R(R + H) = 2 \pi(2r)((2r+2h))\\\\[/tex]
[tex]=2 \ pi \times 2r \times 2 (r+ h)\\\\= 4 \times 2\pi r(r+ h) \\\\= 4 \times surface\ area_{smaller}[/tex]
Therefore, surface area of larger canister is 4 times the surface area of smaller canister.

A pizza delivery man makes $50.00 a shift. If he makes $3.00 on each delivery he makes, how much will he make if he makes 22 deliveries in one shift? Create an equation to represent this situation. Write the equation in function notation. State the ordered pair for 22 deliveries and explain your solution.
Answer:
f(x) = 3x + 50 is the equation in function notation.
(22, 116) is the ordered pair for 22 deliveries.
Step-by-step explanation:
First, create the equation. Let x represent how many deliveries he makes.
Since he makes $3 on each delivery, the total amount he makes from deliveries can be represented by 3x.
He also makes $50 a shift, so add this to 3x in the equation:
f(x) = 3x + 50 is the equation in function notation.
Find how much he will make if makes 22 deliveries. Plug in 22 as x:
f(x) = 3x + 50
f(22) = 3(22) + 50
f(22) = 66 + 50
f(22) = 116
So, he will make $116.
As an ordered pair, the solution is (22, 116).
Answer:
f(x) = 3x + 50
Step-by-step explanation:
If he makes $50.00 a shift, and $3.00 for each delivery, and he makes 22 deliveries in one shift then the equation (in function notation) would be f(x) = 3x + 50. and the solution to the equation is 116.

What is the slope-intercept form equation of the line that passes through (2, 4) and (4, 10)?
O y = -3x - 2
O y = -3x + 2
O y = 3x + 2
O y = 3x - 2
⊹˚ʚ ❑Answer︰The slope is 3!
⊹˚ʚ ❑Explanation︰use the formula y2-y1 over x2-x1
✎Daily reminder: make sure to eat food and stay hydrated, have a good day :D
Answer:
y = 3x - 2.
Step-by-step explanation:
The slope of the line (m) = (10-4)/(4-2)
= 3.
y - y1 = m(x - x1)
y - 10 = 3(x - 4)
y = 3x - 12 + 10
y = 3x - 2.

1. “Systems of Linear Equations”
American Airlines sold a certain number of tickets from Los Angeles to Hawaii. They charged $90
for flight x and the remaining tickets for $250 for flight y. If the airline sold 120 tickets and
collected a total of $27,600 from the sale of those tickets:
a) Set up the System of Linear Equations
b) How many tickets of each flight were sold?
c) How much money was made from each flight?
Answer:
Part A)
[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]
Part B)
Flight X sold 15 tickets and Flight Y sold 105 tickets.
Part C)
Flight X made $1,350 and Flight Y made $26,250.
Step-by-step explanation:
Let the amount of tickets sold by Flight X be represented by x and the amount of tickets sold by Flight Y be represented by y.
Part A)
The airline sold 120 tickets in total. Hence:
[tex]x+y=120[/tex]
Each x ticket costs $90 and each y ticket costs 250. The total income was $27,600. Thus:
[tex]90x+250y=27600[/tex]
Our system of equations is:
[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]
Part B)
Solve the system of equations. We can use substitution. From the first equation, subtract y from both sides:
[tex]x=120-y[/tex]
In the second equation, we can divide everything by 10 and substitute in x:
[tex]9(120-y)+25y=2760[/tex]
Simplify:
[tex]16y+1080=2760[/tex]
So:
[tex]y=105\text{ tickets}[/tex]
Using the equation above:
[tex]x=120-(105)=15\text{ tickets}[/tex]
Flight X sold 15 tickets and Flight Y sold 105 tickets.
Part C)
Since each ticket of Flight X sold for $90 and Flight X sold 15 tickets, Flight X made $1,350.
Then it follows that Flight Y made $26,250.
find value of y step by step hope you will help
Answer:
y = 20 degree
Step-by-step explanation:
angle EOA = 5y (being vertically opposite angles)
angle COE + angle EOA + angle AOD = 180 degree (being linear pair)
2y + 5y + 2y = 180 degree
9y = 180
y = 180/9
y = 20 degree
Answer:
y = 20
Step-by-step explanation:
Angles COE and DOF are vertical angles and are congruent.
m<COE = m<DOF = 2y
<BOA is a straight angle and measures 180 degrees.
m<BOF + m<DOF + m<DOA = 180
5y + 2y + 2y = 180
9y = 180
y = 20

The wheely fast co. Makes custom skateboards for professional riders. They model their profit with the relation P=-2b^2 + 14b - 20, where b is the number of skateboards they produce(in thousands) and P is the company's profit in hundred thousands of dollars. When does wheely fast break even?
Answer:
The answer is below
Step-by-step explanation:
Breakeven point is the point of balance where their is neither a loss or a profit. At the breakeven point, the revenue gotten from the sell of goods is equal to the cost of production of the goods, hence the profit is zero.
Given the profit function:
P=-2b² + 14b - 20
At breakeven P = 0, hence:
0 = -2b² + 14b - 20
-2b² + 14b - 20 = 0
-2b² + 10b + 4b - 20 = 0
-2b (b - 5) + 4(b - 5) = 0
(b - 5)(-2b + 4) = 0
b - 5 = 0; or -2b + 4 = 0
b = 5; or b = 2
Since b is in thousands, hence the company breaks even when the number of skateboards produced is either 2000 or 5000
