Answer:
x = 8mi
Step-by-step explanation:
Use Pythagorean theorem! It states that you can find any side of the triangle using the equation + = . The sides a and b are the sides that are shortest, and c is the longest/slanted side (hypotenuse). So plug in what they give you to get + = ( a and b can be used for either number that is not the hypotenuse). A little bit of basic algebra will lead you to get x=8 mi.
Write the equation of the line that passes through the given points.
Answer:
y=3x-3
Step-by-step explanation:
the y(intercept)= -3 because the point is at -3 on the y-axis. from there the line goes up 3 and over 1. the slope would be 3.
All together the equation of the line is:
Y=3x-3

Answer:
2 apples = .24 kilograms
12 apples = 1.44 kilograms
Step-by-step explanation:
If 5 apples all weigh The same amount. Let x represent one apples weight
5x = 0.60
divide by 5
one apple weighs .12 kilograms
then multiply by the number of apples. So 2 apples is .24
and 12 apples is 1.44

Step-by-step explanation:
If x = 14, which equation is true?
A.3 ( 20 − x ) = 44
B.3 ( 12 − x ) = 6
C.2 ( x − 3 ) = 22
D.2 x − 3 = 22
Answer:
C. 2 ( x − 3 ) = 22Step-by-step explanation:
if x = 14
2 ( x − 3 ) = 22
2 (14 - 3) = 22
2 (11) = 22
22 = 22
therefore, the answer is C.

Answer:
-2
Step-by-step explanation:
So to find slope you just subtract y^1 - y^2 and divide it by x^1 - x^2
The first point is (2, 1)
The second is (0, 5)
1 is our y^1 and 5 is our y^2
1 - 5 = -4
2 is our x^1 and 0 is our x^2
2 - 0 = 2
So our slope is -4/2, reduced its -2
I hope this helped, please mark Brainliest, thank you!

CAN SOMEONE PLEASE HELP ME WITH THIS STATISTICS PROBLEM I DONT UNDERSTAND IT AT ALLL!!!! The mean of a normal probability distribution is 390; the standard deviation is 95. a. Μ ± 1σ of the observations lie between what two values? Lower Value Upper Value b. Μ ± 2σ of the observations lie between what two values? Lower Value Upper Value c. Μ ± 3σ of the observations lie between what two values? Lower Value Upper Value
Answer:
A.)
Lower Value = 295
Upper Value = 485
B.)
Lower Value = 200
Upper Value = 580
C.)
Lower Value = 105
Upper Value = 675
Step-by-step explanation:
Given that mean (M) = 390
Standard deviation (σ) = 95
Lower Value = mean value - number of standard deviations specified
Upper Value = mean value + number of standard deviations specified
a. Μ ± 1σ of the observations lie between what two values?
Lower Value = 390 - 1(95) = 295
Upper Value = 390 + 1(95) = 485
b. Μ ± 2σ of the observations lie between what two values?
Lower Value = 390 - 2(95) = 200
Upper Value = 390 + 2(95) = 580
c. Μ ± 3σ of the observations lie between what two values?
Lower Value = 390 - 3(95) = 105
Upper Value = 390 + 3(95) = 675

BIG POINTS IF YOU ANSWER CORRECTLY PLEASE ANSWER ASAP number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth?
1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles.
1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles.
2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.
Answer:
It should be the second one

Suppose that y is inversely proportional to the 4th power of x, and that y=15 when x=5. What is y when x=7? Round your answer to two decimal places if necessary.
Answer:
y = 3.91 when x =7
Step-by-step explanation:
y = k / x⁴
Where,
k = constant of proportionality
y=15 when x=5
y = k / x⁴
15 = k / 5⁴
Cross product
15 × 5⁴ = k
15 × 625 = k
9,375 = k
What is y when x=7?
y = k / x⁴
= 9,375 / 7⁴
= 9,375 / 2401
= 3.9046230737192
Approximately
y = 3.91
First answer the problem 3,216 divided by 8 and ur quotiont/answer u then will look at the answer and find the first diget and then answer what place is that didet in.
Answer:
Quotient/Answer = 402
Hence the first digit is 4 and it's place value = hundreds
Step-by-step explanation:
Quotient = Dividend ÷ Divisor
Dividend = 3216
Divisor = 8
Quotient = 3216 ÷ 8
= 402
We are asked to find the place value of the first digit
Hence the first digit is 4 and it's place value = hundreds
Find the length of the arc on a circle with a radius of 7 centimeters and a central angle of 74 degrees
Answer:
Length of arc: 9.04cm
Step-by-step explanation:
Circumference = pi x diameter (or radius times 2 in this case)
C = pi x (7 x 2)
C = pi x 14
C is equal to around 43.98cm
In order to find the length of the arc, you use the central angle and turn it into a fraction, and then multiply that fraction by the circumference.
74 degree angle/ 360 degrees --> 74/360
74/360 x 43.98 = 9.04cm

wood that are 8' long each.
You need 15 pieces cut 3' long,

The Ride-It Store rents bicycles.The cost is $8.50 for 1 hour, $13.65 for 2 hours,$18.80 for 3 hours, and $23.95 for 4 hours.If the pattern continues, how much will it cost Nate to rent a bike for 6 hours?
Answer:
in six hours it would be $34.25
Step-by-step explanation:
The computation of the total cost for 6 hours is shown below:
For one hour it would be $8.50
For two hours
= $13.65 - $8.50
= $5.15
For three hours
= $18.80 - $13.65
= $5.15
For four hours
= $23.95 - $18.80
= $5.15
For five hours
= $23.95 + $5.15
= $29.10
For six hours
= $29.10 + $5.15
= $34.25
Hence, in six hours it would be $34.25

The solution to this system of linear equations will be (–1, 3). Then the correct option is D.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
The equations are given below.
y − 4x = 7 ...1
2y + 4x = 2 ...2
Add both equations, then we have
3y = 9
y = 3
Put y = 3 in equation 1, then we have
3 − 4x = 7
4x = –4
x = –1
The solution to this system of linear equations will be (–1, 3).
Then the correct option is D.
