Answer:
m∠C = 56 and (4x + 16) = 180
Step-by-step explanation:
The sum of angle in a triangle is 180, hence:
<A+<B+<C = 180
Given
<A = 2x+1
<B = x
<C = x+15
Substitute
2x+1+x+x+15 = 180
collect like terms:
2x+x+x+1+15 = 180
4x+16 = 180
4x = 180-16
4x = 164
Divide both sides by 4
4x/4 = 164/4
x = 41°
Since <A = 2x+1
<A = 2(41)+1
<A = 82+1
<A = 83
<B = x = 41
<C = x+15
<C = 41+15
<C = 56
Based on the calculation above, the true statements are:
m∠C = 56 and (4x + 16) = 180

Robert was using a bucket that holds 243.5 ounces (oz) of water when full. The bucket loses 0.3 oz of water per second. After 20 seconds, Robert noticed the leak and plugged the leak. How much water, in ounces, remained in the bucket?
-Note from user: Hello! Could you please help me? I want to learn how to do this in the future so it would be appreciated if u add an explanation to your answer, thanks and please respond before 11:59)
Answer:
237.5
Step-by-step explanation:
Since the bucket loses 0.3 oz of water per second, and 20 secs passed, you would have to multiply 0.3 and 20 to find out how much water leaked. And 0.3x20=6, so then, we would have to subtract 234.5 and 6 to find out how much water there is left in the bucket. 234.5-6=237.5
So 237.5 is your answer

Jamil finds that he reads 1/5 of his 115-page book in 1/4 hour
Answer:
He will read 92 pages in an hour going by the current rate at which he reads
Step-by-step explanation:
The complete question is as follows;
Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour
We proceed as follows;
If he reads 1/5 of 115 in 1/4 hour
1/5 of 115 pages refer to 1/5 * 115 = 23 pages
This means that he reads 23 pages in quarter of an hour
So in an hours the number of pages he will read will be 23 * 4 = 92 pages

Write an equation for the n th term of the arithmetic seqeuence. Then find a 10
-6, – 9. - 12. - 15, .
Answer:
3n-9
Step-by-step explanation:
Each term increases by 3, so there n should be multiplied by 3.
If the first term (or when n = 1) is -6 and we have 3n, we need to subtract 9 to get -6. This also works for the other terms in the sequence.
The 10th term of the sequence would then be:
3(10)-9

What is the linear relationship?
A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
The given graph represents the relationship between the number of times he visited the club and his total monthly cost.
As per the given graph, we can conclude as follows:
The type of variation in this relationship is a direct variation because the points are increasing, and the initial value is 20 because the coordinate of the initial point is (0, 20).
Hence, the correct answer would be option (C).

2. Solve for x. SHOW YOUR WORK.
Answer:
x=9
Step-by-step explanation:
The two labelled angles are equal, so we can construct an equation. Then, we solve the equation for x.
[tex]4x+2=7x-25\\2=3x-25\\3x=27\\x=9[/tex]
First, we subtract 4x from both sides. Next, we add 25 to both sides. Finally, we divide both sides by 3.

Answer:
D but dont get mad
Step-by-step explanation:
Identify an equation in point-slope form for the line perpendicular to
y=-1x +11 that passes through (4, -8).
O A. y +8 = 2(x-4)
B. y - 4 = 2(x+8)
O C. y+8 = {(x-
-4)
O D. 7-8 = {(x + 4)
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12

Another term to represent Unit Rate is?
Constant of Proportionality
Slope
Rate of Change All of the Above
None of the Above
Answer:
All of the above.
Step-by-step explanation:
In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.
Therefore, the unit rate is the same as the rate of change.
And the rate of change is synonymous with the slope.
The constant of proportionality is simply the slope/rate of change for proportional equations.
Therefore, the constant of proportionality is also another word for the unit rate.
Our answer is hence all of the above.

See the diagram attached:
In a triangle, the sum of interior angles is equal to the exterior angle.
According the diagram, the sum of interior angles is given as:
Sum of interior = <FDE+<DEF
Given
<FDE = 2x+4
<DEF = 3x+5
Sum of interior = 2x+4+3x+5
Sum of interior = 5x+9
Exterior angle = <EFG = 7x-5
Equate the interior to the exterior and calculate the value of x:
5x+9 = 7x-5
Collect like terms
5x-7x = -5-9
-2x = -14
x = -14/-2
x = 7
Next is to get <FDE:
<FDE = 2x+4
<FDE = 2(7)+4
<FDE = 14+4
<FDE = 18°
Hence the measure of <FDE is 18°

C
Step-by-step explanation:
Some investments in the stock market have earned 10% annually. The total value of the
investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the
investment, and n is the number of years the money is invested. If $1.000 is invested in the
stock market at this annual rate of return, what is the expected total value after 18 years?
$4,054.47
$5,559.92
$18,700.00
$19,800.00
Answer:
$5,559.92.
Step-by-step explanation:
NB: Please note that the $1.000 is not correct. If we use it the none of the option will not be correct which means that the value was a mistake. Obviously, It should have been a ''comma'' instead of a ''full stop''. So, it should be ''...$1,000 is invested...'' and not ''...$1.000 is invested...''
So, without mincing words let us dive right into the solution of this particular problem/question.
We have that the '' total value of the investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the investment, and n is the number of years the money is invested.''
Using the rate given to us, The expected total value after 18 years =A = P(1.10)^n = $1,000 × (1.10)^18 = $5,559.92.
Answer:
$5,559.92
