Answer:
18 sides
Step-by-step explanation:
Exterior angle = 360° ÷ n
20° = 360°/n
n× 20 = 360/n ×n
20n = 360
n= 360/20
n = 18
Steps on solving equations and formulas example: rt - 2n = y, for t
Answer: t = [tex]\frac{y}{r} + \frac{2n}{r}[/tex]
Step-by-step explanation:
rt - 2n = y Add 2n to both sides
+2n +2n
rt = y + 2n Divide both sides by r
t= [tex]\frac{y}{r} + \frac{2n}{r}[/tex]
Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty while driving through Canada Samuel notice that each gas station measures its gasoline in litres instead of gallon Samuel found that one is approximately equivalent to 0.264 gallons how many liters would it take to fill Samuels car round to the nearest tenth of a liters
Answer: 47.4 liters
Step-by-step explanation:
From the question, we are informed that Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty and while in Canada, he noticed that one liter is equivalent to 0.264 gallons.
The number of liters it'll take to fill Samuels car will be:
= 12.5/0.264
= 47.4 litres

Please help me with this equation. It’s solving systems of equations.
Moving downstream (with the current), the boat moves at a rate of (252 mi)/(12 h) = 21 mph. Upstream (against the current), it moves at a rate of (252 mi)/(84 h) = 3 mph.
When traveling downstream, the boat's speed is the sum of its own speed in still water and the speed of the current. It's the same going upstream, but the boat and current move in opposite directions. Let b and c denote these speeds, respectively. Then
downstream: b + c = 21 mph
upstream: b - c = 3 mph
Adding these equations eliminates c and lets us solve for b :
(b + c) + (b - c) = 21 mph + 3 mph
2b = 24 mph
b = 12 mph
Now solve for c :
12 mph + c = 21 mph
c = 9 mph
REASONING A newspaper company has three printing presses that together can produce 3500 newspapers each
hour. The fastest printer can print 100 more than twice the number of papers as the slowest press. The two slower
presses combined produce 100 more papers than the fastest press. How many newspapers can each printing press
produce in 1 hour?
Answer:
X = 1,700; Y = 1,000; Z = 800
Step-by-step explanation:
I could have sworn I answered this??? Sorry! Brainly, why wouldn't you let me answer this last night??? Anyway, for these types of problems, use X, Y, and Z for the three things you need to solve. First, we know that X (the fastest printer) = 100 + 2Z, where Z = the slowest printer. Z + Y = 100 + X or Z + Y = 100 + ( 100 + 2Z). --> Y - 200 = Z and Y = Z + 200. Next, we can add X + Y + Z together and set it equal to the full amount of newspapers, 3,500. Which would stand as 100 + 2Z + Z + 200 + Z = 3,500, let's try to solve for Z first, since it'll be super easy. We get 300 + 4Z = 3,500 --> 4Z = 3,200 --> Z = 800. Y = 200 + 800 = 1,000 and X = 100 + 2*800 = 1,700. And Z + Y = 800 + 1,000 = 1,800, which is 100 papers more than the fastest printer.

Harper Hospital treated 423 patients last week who were children, out of a total of 931 patients. The administrator calculates that they had 408 adult patients. Is the administrator's calculation reasonable? Estimate the number of adult patients by rounding the numbers to check the administrator's calculation.
Answer:
No, the administrator is wrong.
[tex]Adult = 500[/tex]
Step-by-step explanation:
Given
[tex]Total = 931[/tex]
[tex]Children = 423[/tex]
[tex]Adult = 408[/tex]
Solving (a): Is the administrator correct?
No, the administrator is wrong.
This is so because: when the number of children is subtracted from the total patient, the remaining number is not 408
Solving (b): Estimate the number of adults
By rounding up:
[tex]Adult = Total - Children[/tex]
Actual Figures
[tex]Adult = 931 - 423[/tex]
Round up
[tex]Adult = 900 - 400[/tex]
[tex]Adult = 500[/tex] -- approximately
A nursery owner buys 9 panes of glass to fix some damage to his greenhouse. The 9 panes cost $22.05 Unfortunately, he breaks 4 more panes while repairing the damage. What is the cost of another 4 panes of glass?
Answer: $9.80
Step-by-step explanation:22.05/9=2.45x4= 9.80
Answer:
$4.30
Step-by-step explanation:
Two panes of glass cost $4.30.
Explanation
First find the cost of one pane of glass (the "unit cost")
7 panes of glass cost
$
15.05
, so one pane of glass costs
15.05
÷7∩
$2.15 ← cost of one pane of glass
Then use that answer to find the cost of two panes of glass
If one pane of glass costs $2.15, then 2 panes cost 2× $2.15 $4.30 ← cost of two panes of glass
Answer:
Two panes of glass cost $4.30.

f(x) = 3x - 8 and g(x) = -x - 4. Find (f + g)(x) and (f + g)(5).
Answer:
(f+g)(x) = 3x - 8 -x -4
(f+g)(x) = 2x-12
(f+g)(5) - substitute 5 into x
(f+g)(5) = 2(5)-12
(f+g)(5) = 10-12
(f+g)(5) = -2

2. A package delivery service has a truck that can hold 4200 pounds of cargo
and has a capacity of 480 cubic feet. The service handles two types of
packages: small, which weigh up to 25 pounds each and are no more than 3
cubic feet each; and large, which are 50 pounds each and are 5 cubic feet
each. The delivery service charges $5 for each small package and $8 for each
large package. Let x be the number of small packages and y be the number of
large packages in the truck. What is the maximum revenue per truck?
Answer:
$680
Step-by-step explanation:
Capacity of the truck: 4200 pounds and 480 cubic feet of cargo.
Small package: 25 pounds and 3 cubic feet each.
Large package: 50 pounds and 5 cubic feet each.
For x number of small packages:
25x pounds and 3x cubic feet
Let x = 8,
200 pounds and 24 cubic feet.
For y number of large packages:
50y pounds and 5y cubic feet
Let y = 80,
4000 pounds and 400 cubic feet.
Since delivery service charges $5 for each small package and $8 for each large package.
The maximum revenue per truck = ($5x + $8y)
= ( $5 x 8) + ($8 x 80)
= $680

Identify the factored form of each polynomial. 4r + 11x + 6 4x + 10x + 6 11. 4r + 14x +6 (4x+3)(x+2) :: (x+3)(4x + 2) :: (2x+3)(2x + 2)
Answer:
1) 4x^(2)+11x+6 Factored--> (4x+3) (x+2)
2) 4x^(2)+10x+6 Factored--> (2x+3)(2x+2)
3) 4x^(2)+14x+6 Factored--> (x+3)(4x+2)
Step-by-step explanation:
Factor: 4x^(2)+11x+6 (step by step)
1) Split the second term (11x) into two terms
4x^2 + 8x + 3x + 6
2)Factor out common terms in the first two terms, then in the last two terms.
4x(x + 2) + 3(x + 2)
3) Factor out the common term x + 2
(x + 2) (4x + 3)

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

The density of a certain material is such that it weighs 4 kilograms
per cubic foot of volume. Express this density in ounces per cubic
meter. Round your answer to the nearest whole number.
Answer:
4986 ounces/m³
Step-by-step explanation:
1 kilogram = 35.274 ounces
1 cubic foot = 0.0283 cubic metre
We are converting kg/ft³ to ounces/m³
Hence:
4kg/ft³ × 35.274 ounces/ 1 kg × 1 ft³/0.0283m³
= 4985.7243816 ounces/m³
Approximately to the nearest whole number = 4986 ounces/m³

Jordan opened a savings account with $320 and deposits $25 into his saving account weekly.
How much would Jordan have after 36 weeks?
Answer: $1,260
Explanation: Because Jordan is depositing $25 every week, for 36 weeks, we'd need to multiply 25 x 36. The product would be $900. But since Jordan had $360, we need to add 900 + 360 to get the final sum. Therefore, Jorndan would have $1,260 after 36 weeks.
