QS bisects ∠PQR. If m∠PQS = (5x)⁰ and m∠RQS = (2x + 6)⁰, then what is m∠PQR? Draw a picture and label before solving. *
Answer:
m∠PQR = (7x + 6)⁰
Step-by-step explanation:
Please find the diagram in the attachment.
Mathematically, since the angle PQR is bisected by the given line, it means that;
RQS + PQS = PQR
Thus;
PQR = (2x + 6) + 5x
PQR = 2x + 6 + 5x
PQR = 7x + 6
m∠PQR = (7x + 6)⁰
What is the slope of the line that goes through (5,-11) and (-9, 17)?
Answer:
-2
Step-by-step explanation:
We can use the slope formula

Step-by-step explanation:
11) -14 - 8x = -2(-3x + 7)
Needing some help with this
Answer:
x = 0
Step-by-step explanation:
First, distribute the -2 to the parentheses:
-14 - 8x = -2(-3x + 7)
-14 - 8x = 6x - 14
Add 14 to both sides:
-8x = 6x
Subtract 6x from both sides:
-14x = 0
Divide each side by -14:
x = 0
So, x = 0
Answer:
0
Step-by-step explanation:
-14-8x=6x-14(cancel equal terms)
-8x=6x(move the variable to the left)
-8x-6x=0(collect like terms)
-14x=0Divide both sides)
x=0
during a musical an orchestra is playing. as the music plays, the volume changes in the beginning of the piece can be modeled by the equation s=10|x-4|+50 where s represents the sound level in decibels and x represents the number of measures of music played. explain in words each step to find the following question:
at what number(s) measures played would the sound level be at 80 decibels?
Answer:
X = 1 ; x = 7
Step-by-step explanation:
Given the equation:
s=10|x-4|+50
s = sound level in decibels ; x = number of measures of music played
Take away 50 from Both right hand and left hand side of the equation
Recall s = 80
80 - 50 = 10│x - 4│+ 50 - 50
30 = 10│x - 4│
To get rid of the absolute value sign, append ± to left hand side
± 30 = 10x - 40
Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1
Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7
On average, Asia makes 14 out of 20 free throws. Assuming the relationship is proportional, how many more free throws is she likely to make if she shoots 150 free throws?
Answer:
105 free throws made if Asia shoots 150
Step-by-step explanation:
Find the percentage form of 14 out of 20
14 / 20 = 0.7 (70%)
Then calculate 70% of 150:
0.7 multiplied by 150 = 105
(Can check by doing 105 / 150 = 0.7)
Asia will make 1058 free throws out of a total of 150 shoots.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that,
Asia makes 14 out of 20 free throws
Percentage free throws = free throws/total × 100
Percentage free throws = 14/20 × 100
Percentage of free throws = 70%
Now,
If Asia throws 150 then with the same proportion she will again make 70% of her throw free.
So,
70% of 150 = 150 × 70/100 = 105
Hence "Asia will make 1058 free throws out of a total of 150 shoots".

Answer:
y=9
Step-by-step explanation:
Plugin what we know
[tex]\frac{y}{12} =\frac{3}{4}[/tex]
Simplify the equation by using cross-multiplication
4y=36
Divide both sides of the equation by 4
y=9
If this helped, please rank me brainliest! :)
Answer:
Y would be 9
Step-by-step explanation:
If the x is 12 and it shows the simplified version take the 4 and multiply it by how much you would need which is 3 so you go to the 3 above 4 and multiply it by 3 and you will get 9/12

What is the formula for finding slope?
Answer:
To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

(6×10^2) ÷ (3×10^-3)
Answer:
2*10²
Reduce the expression, if possible, by cancelling the common factors.
Scientific Notation:
Hi!
Lets go through this together.
Using the operation, PEMDAS, we start from left, then go to right.
since there are two pairs of parenthesis, we start with the one on the left.
(6x10^2)
so now, we do the exponent, 10^2
10x10= 100
So our answer for this part is 100.
Now we have (6x100)
6x100=600
So now, the equation is 600÷(3x10^-3)
Now, we do the parenthesis on the right.
(3x10^-3)
First, we do the exponent, 10^-3
10x-10x-10= 1,000
so now, the equation is (3x1,000)
Now, we multiply.
3x1,000=3,000
So now, the equation is 600 ÷ 3,000
600 ÷ 3,000 = 0.2
So, your answer is 0.2.
__________________________________________________________
(6 x 10^2) ÷ (3 x 10^-3)
=(6 x 100) ÷ (3 x 10^-3)
= 600 ÷ (3 x 10^-3)
= 600 ÷ (3 x 1,000)
= 600 ÷ 3,000
= 0.2
(also, the scientific notation is 2x10^2)

An athlete is jumping. However, every time she jumps she gets a bit more tired, and every jump goes 1/2 as far as her prior jump. Now, for her very first jump, she goes 1/2 of a foot. On her second jump, she goes 1/4 of a foot, and so on and so forth. How many jumps does it take for her to travel 1 foot?Immersive Reader
Answer:
She will never complete 1 foot
Steps:
1) We will find the maximum value of this process, when this is carried out infinite times.
This process goes like a Infinite GP, whose
First term,a = 1/2ft.
Common Ratio, r = 1/2ft.
Maximum value of this process is One Foot when the athlete jumps forever or Practically, she will never complete her 1 foot.
Hence, Athlete will never complete. her complete .
Starting from 1/2 ft. ,and ending at 1 foot.
The value always tends toward 1 but never reaches one.
A finance magazine did a survey and found that the average American family spends $1,600 on a summer vacation. If the distribution is normal with standard deviation $411, find the amount a family would have spent to be the 80th percentile. PreviousNext
Answer:
$1945Step-by-step explanation:
Let X be the normal distribution
Kindly find attached a detailed annotation of the solution to the problem.
in the attached document, we found the value that corresponds to 80th percentile, hence we found the value such that the probability that the variable x is lower than this value is 0.8.
Also, from the calculation, we found that the value which corresponds to the 80th percentile is $1945
An online streaming service deducts $7 from Serena’s account every month of a year. After 1 year, how much do the streaming service fees change Serena’s account?
Answer:
$84
Step-by-step explanation:
This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.

A triangle has sides with lengths of 38 feet, 56 feet, and 69 feet. Is it a right triangle?
Answer:
No
Step-by-step explanation:
Assume that it is a right triangle for now
According to the Pythagorean Theorem...
(38)^2 + (56)^2 = (69)^2
4580 ≠ 4761
Both sides are not equal, and hence the Pythagorean Theorem can't be applied to the triangle. It is not a right triangle.

A parking lot is 20 feet long. One tortoise starts at the edge of the parking lot and moves at a rate of 6 feet per minute. Another tortoise starts 4 feet from the edge of the parking lot and moves 2 feet per minute. Write an equation to represent when they will be in the same spot.
Answer:
Kindly check explanation
Step-by-step explanation:
Length of parking lot = 20 feets
Speed of tortoise which starts at the edge = 6 feets per minute
Speed of tortoise which starts 4 feets from the edge = 2 feets per minute
Equation to represent when they will be in the same spot.
Distance = speed * time
Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)
Distance of the other tortoise = (4 + 2t) - - - (2)
Equating both (1) and (2)
6t = 4 + 2t
6t - 2t = 4
4t = 4
t = 4/4
t = 1
Hence, they'll be at the same spot after 1 minute.
