Answer:
[tex]x=7\sqrt{2}\\y=7[/tex]
Step-by-step explanation:
Find the last angle of the triangle.
The sum of all the angles in a triangle is 180 degrees.
Y+90+45=180
Y = 45
Find x:
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.
sin(B)=opp/hyp
rewrite as
x=7/Sin(45)
x = 7squareroot 2
Find the last side of the triangle using the Pythagorean theorem.
y=√(7√2)^2−(7)^2
y=7
The difference between two numbers is 7. The sum of three times the larger number and twice the smaller number is 16.
Drag and drop the correct options from the list menu to make each statement below true.
Answer:
28 and 12 . (QUORA)
Step-by-step explanation:
Let’s write this down. We are looking for X and Y.
The difference between two numbers is 16: −=16
Three times the larger number is seven times the smaller: ∗3=∗7
So, we need to solve X and Y from these two equations.
If we re-arrange X*3 = Y*7, we get Y = X*3/7.
So, −∗3/7=16 . −∗3/7 is the same as 7∗/7−3∗/7 , or 4∗/7 . So 4∗/7=16−>4∗=7∗16−>=7∗4=28 .
Then we just go back to −=16 , and =28 , gives us 28−=16, or =28–16−>=12 .
So the numbers are 28 and 12.

SAT scores are normally distributed with a mean of
500 and a standard deviation of 60. Find the z-score
of an SAT score of 380.
Answer:
the z-score for the sat score of 380 is 2
Step-by-step explanation:
the way i got this is you got to take the standard deviation value and subtract it from the mean since the value 380 is less than 500.
500-60=440-60=380
so the answer would be a z-score of 2
When Mayerlin goes bowling, her scores are normally distributed with a mean of 175 and a standard deviation of 13. Using the empirical rule, what percentage of the games that Mayerlin bowls does she score between 162 and 188?
Answer:
68%
Step-by-step explanation:
The Empirical rule formula is given as:
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .
Where
μ is the population mean
σ is the population standard deviation.
Step 1
Find the number of standard deviations from the mean
μ - xσ and μ + xσ
μ = 175
σ = 13
For 162
175 - 13x = 162
175 - 162 = 13x
13 = 13x
x = 13/13
x = 1
For 188
175 + 13x = 188
13x = 188 - 175
13x = 13
x = 13/13
x = 1
Hence, the data falls with 1 standard deviation of the mean
Therefore, percentage of the games that Mayerlin bowls does she score between 162 and 188 is 68%
Answer:
The answer is 68%

How much money would you have if you invested $2500 at 5.75% annual interest, compounded quarterly for 5 years
Answer:
[tex]A\simeq3325.91[/tex]
Step-by-step explanation:
The amount formula in compound interest is:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
where:
P = principal amount
r = annual interest
n = number of compounding periods
t = number of years
We already know that:
P = $2500
[tex]r = 5.75\% = \frac{5.75\%}{100\%}=0.0575[/tex]
t = 5
n = 4 (quarterly in a year)
Then,
[tex]A=2500(1+\frac{0.0575}{4} )^{(4)(5)}\\\\A=2500(1+\frac{0.0575}{4} )^{20}\\\\A=3325.911985\\\\A\simeq3325.91[/tex]

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
The test contains 4 three-point questions and 20 five-point questions.
The test contains 10 three-point questions and 14 five-point questions.
The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.
Answer:
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
We can substitute a definition of one of the variables by rearranging the first equation.
We set the first equation equal to one of our two variables.
[tex]y = 24 - x[/tex]
Now we substitute this equality into our second equation
[tex]3x + 5(24 - x) = 100[/tex]

find the slope of the line going through the points (2,-3) and (-1,15) in the simplest form
Answer:
y=-2x
Step-by-step explanation:
You could find the slope of line going through the points (2,-4) and (-1,2). It is
slope is -6/3 or -2
So the line is
Now plug in one of the points and the slope into point slope form and find the line
y+4=-2(x-2) or
y+4=-2x+4 so
y=-2x
Check it by making sure BOTH points are on the line. Plug the values into the equation you found for the line.
-4=-2(2)
2=-2(-1)

Sam built a fence that was 54 feet 54 feet54, start text, space, f, e, e, t, end text long. She built the same length of fence each day for 6 66 days.
Answer:
Inches of fence Sam built each day = 108 inches per day
Step-by-step explanation:
Sam built a fence that was 54 feet long. She built the same length of fence each day for 6 days.
How many inches of fence did Sam build each day?
Total length of fence Sam built = 54 feet
How many inches of fence did Sam build each day?
Number of days = 6
Convert 54 feet to inches
1 feet = 12 inches
54 feet = 648 inches
Inches of fence Sam built each day = Total inches of fence built / number of days
= 648 inches / 6 days
= 108 inches per day
Inches of fence Sam built each day = 108 inches per day

Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Use the slope formula:
slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex][tex]\frac{1}{3}[/tex]
Let:
[tex](x_1 , y_1) = (-5 , 1)\\(x_2 , y_2) = (4 , 4)\\[/tex]
Plug in the corresponding numbers to the corresponding variables:
[tex]m = \frac{4 - 1}{4 - (-5)} = \frac{3}{4 + 5} = \frac{3}{9}[/tex]
Simplify the fraction. Divide common factors from both the numerator and denominator:
[tex]\frac{(\frac{3}{9} )}{\frac{3}{3} } = \frac{1}{3}[/tex]
[tex]\frac{1}{3}[/tex] is your answer.

The two rays are LM→ & LK→ form the angle ∠KLM
What is an angle?
In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
So, here, the rays LM-> & LK-> form the angle ∠KLM.
Hence, The two rays are C. LM→ & F. LK→ form the angle ∠KLM.
