Two angles are supplementary if their measures add up to 180°. If one of two supplementary angles is (3x + 7)° while the other is (5x - 11), then x =
A.25
B.21
C.24
D.20
E.23
Answer:
E. 23
Step-by-step
3x + 7 + 5x - 11 = 180
* add 3x and 5x
8x + 7 - 11 = 180
* do 7-11
8x - 4 = 180
* add 4 to both sides to cancel it out
8x = 184
* divide 8 on both sides to get x alone
x = 23
Joshua borrows $300 from his older sister to buy a bike. He promises to pay the total amount plus 5% simple interest in one year. How much will Joshua
pay back in all?
Answer:
315
Step-by-step explanation:
Joshua was offered a job that paid a salary of $77500 in its first year . The salary was set to increase by 2% per year every year. If Joshua worked at the job for 5 years what was the total amount of money earned over the five years . to the nearest whole number
i think you have to use the sum of finite geometric series
a1=77,500
n=5

Terry flips a coin 150 times.Make a prediction that the coin will come up tales
A Exactly 300
B Close to but not exactly 300
C Exactly 75
D Close to but not exactly 75
Answer:
its either C or D
Step-by-step explanation:
there are 2 possible outcomes for getting either heads or tails so if we divided 150 by 2 we get 75, so about 75 times you could get tails.
so maybe it is D, but im not sure

The sum of three consecutive numbers is 84. What is the largest of these numbers? (5 points) a 28 b 26 c 29 d 27
Answer:
The answer is c.29
Step-by-step explanation:
I used Google xD
Answer:
Largest number = 29
Step-by-step explanation:
Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)
x +1 + x + 2 + x + 3 = 84 {Combine like terms}
x + x +x + 1 + 2 + 3 = 84
3x + 6 = 84
3x = 84 - 6
3x = 78
x = 78/3
x = 26
Largest number = x + 3 = 26 + 3
=29

Which linear equation matches this graphed line?
y = 2x + 5
y = 1/2x-5
y = 2x+5
y = 1/2x + 5
Answer:
I think one of the choices was entered incorrectly. You have y=2x+5 listed twice. I believe the answer is y=-2x+5
Step-by-step explanation:
5 is the y-intercept and it is a +5 because it is above the x-axis. Slope = rise/run. In this case the slope should be negative thus -2x. Hope this helps.
Mrs. Garcia borrowed some money at the rate of 4% per annum for the first year, at the rate of 6% pe r annum for the next 2 years, and at the rate of 7.5% per annum for the period beyond 3 years. If he pays a total interest of ₱ 15 750 at the end of 5 years, how much money did he borrow?
Answer: ₱40,909.1
Step-by-step explanation:
Given data:
Rate for first year = 4%
Rate for next two years = 6%
Rate for the next 3 years = 7.5%
Interest paid back after 5years = ₱ 15,750
Solution:
How much did she borrow.
= let the sum borrowed be P
= P * 4 / 100
= 4P/100
= 1P/25.
For the next two years
= P* 6 * 2/100
= 12P/100
= 3P/25
For the next 3years
= P* 7.5*3/100
= 22.5P/100
= 9P/40.
1P/25 + 3P/25 + 9P/40 = 15750
77P/200 = 15750
P = 15750 * 200 / 77
P = 315,0000/77
P = ₱40,909.1
The amount borrowed is ₱40,909.1
Solve the system of linear equations by multiplying.
{−2x + 2y =4
{−4x + 8y =24
Answer:
The solution set is (2,4).
Step-by-step explanation:
Given that:
−2x + 2y =4 Eqn 1
−4x + 8y =24 Eqn 2
Multiplying Eqn 1 by -2
-2(-2x+2y=4)
4x-4y= -8 Eqn 3
Adding Eqn 2 and 3
(-4x+8y)+(4x-4y)=24-8
-4x+8y+4x-4y=16
4y=16
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{16}{4}\\y=4[/tex]
Putting y=4 in Eqn 1
-2x+2(4)=4
-2x+8=4
-2x=4-8
-2x=-4
Dividing both sides by -2
[tex]\frac{-2x}{-2}=\frac{-4}{-2}\\x=2[/tex]
Hence,
The solution set is (2,4).

A student has a container with the volume 1.5 liters. She estimates the volume to be 1.2 liters. By what percent is the student's estimate off? I don't need a step-by-step explanation, I just want the right answer.
Answer:
20%.
1.2/1.5 = 0.8
0.8*100 = 80%
100%-80% = 20%.
We can verify this:
1.5-20% = 1.2.
Answer: 20%

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 95,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 4% each year. How many total fish did the company catch over the first 14 years, to the nearest whole number?
Answer:
54,265 fishes
Step-by-step explanation:
The formula for Population decrease =
P(t) = Po × e^-rt
Where
P(t) = Population after time t
Po = Initial population = 95000
r = decrease rate = 4% = 0.04
t = time in years = 14
Hence
P(t) = 95,000 × e ^- 0.04 × 14
P(t) = 95,000 × e^-0.56
P(t) = 54264.861066 fishes
Approximately = 54,265 fishes
The total fish the company caught over the first 14 years, to the nearest whole number is 54,265 fishes

Answer:
The slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.
Step-by-step explanation:
From the line equation, let us take two points
(0, 2)(4, 1)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]m=\frac{1-2}{4-0}[/tex]
[tex]m=-\frac{1}{4}[/tex]
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be:
[tex]-\frac{1}{-\frac{1}{4}}=4[/tex]
Thus, the slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.

Step-by-step explanation:
f(x) =∛2x g(x)=2x+1 Find (f/g) (x) Include any restrictions on the domain
Answer: ∛2x / 2x+1
x cannot equal -1/2
Step-by-step explanation: f/g means we divide the f function by the g function
so that’s all we do!
then, remember, we can’t divide by 0. so 2x+1 can’t be 0. if we solve that out, we get that x can’t be -1/2, because that would make it 0. there’s our domain restriction!
