Help pls 10 points
A x=56
B x=156
C x=166
D x=66
D: x=66
Step-by-step explanation:
As we know the angle is 90 degree.Then x+24 degree is equal to 90 degree as whole part axiom. If we subtract 24 from 90 we get 66

A line with a slope of -1 passes through the point (5,6). What is its equation in point-slope form?
Answer:
y - 6 = -(x - 5)
Step-by-step explanation:
Start with the general point-slope form y - k = m(x - h).
Here m = -1, h = 5 and k = 6, and so, after substitutions, we have:
y - 6 = -(x - 5)
It’s an emergency help!
Answer:
24m^2
Step-by-step explanation:
to get the length, we have to follow this equation:
2W + 2L = P
2(4) + 2L = 20
8 + 2L = 20
8 + 2(6) = 20
to get the area from this information, we have to follow this equation:
A = W • L
A = 4 • 6
A = 24m^2

What is X and Y? I will give brainliest to whoever shows work and explains how to do the problem and if its correct.
Answer:
x = 5([tex]\sqrt{3}[/tex])
y = 10
Step-by-step explanation:
1st, we need to find the angles on the triangle before we can solve for side lengths.
Line Y is intercepted by line X which forms 2 supplementary angles.
These angles add up to 180 so 180 - 150 = 30 therefor the angle is 30 degrees
Next, using the vertical angle theorem, we see that there is a right angle and using this theorem, we can determine this is a right triangle and that angle is 90 degrees
Using the triangle sum theorem, we know a triangle's sum is = to 180 degrees
90 + 30 + x = 180
120 + x = 180
x = (180 - 120)
x = 60
We now determined this is a 90-60-30 triangle
The opposite of the 30 degree angle is the 5 unit measurement
According to this theorem 5 is equal to x because the side opposite of the 30 degree angle is = to x (not the side variable, the variable for this theorem)
We now solve the rest
x = 5
2x (opposite of 90 degrees) = 10
5x = 5([tex]\sqrt{3}[/tex]) (This is in its simplest form)
So now based upon this,
x = 5([tex]\sqrt{3}[/tex])
y = 10

How to find mean: add up all the numbers and divide by how many numbers
19, 19, 20, 20, 20, 21, 22, 22, 22, 22, 23
(19+19+20+20+20+21+22+22+22+22+23)/11=230/11=20.9(rounded)
If the new mean is 22, sum of all the numbers is 22 times 12=264

If
x + 2y = 1
X– 2y = 13
then y =
Answer:
y = -3
Step-by-step explanation:
x + 2y = 1 then x = 1 - 2y
x– 2y = 13
substitute for x:
1 - 2y - 2y = 13
simplify:
-4y = 12
y = -3
x = 7
5. Use long division method to calculate 102 024 ÷ 156
Using long division 1020 ÷ 156 is equal to 654.
What are some alternative names for arithmetic operations?Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.
Given, 102024 is divided by 156.
First, we'll take up to 1020 ÷ 156 then we'll have a reminder of two-digit and a quotient of 1 digit we will bring down the next digit and continue the process until it is completely divisible or we have a remainder than is less than 156.
1020 ÷ 156
= 654.

A cylinder has a height of 19 centimeters and a radius of 10 centimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer: 5966cm³
Step-by-step explanation:
The volume of a cylinder is calculated using the formula:
Volume = πr²h
where, π = 3.14
radius = 10cm
Height = 19cm
Volume = πr²h
= 3.14 × 10² × 19
= 3.14 × 100 × 19
= 5966.00cm³

b) x = -2 (I assume you have to find x, but the question isn't very clear)
Step-by-step explanation:
a) f(3) = -4(3) - 7 = -12 - 7 = -19
b) Suppose f(x) = 1. Then 1 = -4x - 7, so -4x = 8, and thus x = -2

what is the x intercept of a line that has a slope of 2/3 and passes through the point (-2,2)?
Answer:
-3
Step-by-step explanation:
use the equation y = mx + b where m is the slope and b is the y-intercept so just plug in what you know. y = 2/3x + 2 then solve the equation for x . To do that, just put y = 0 so then it would be -2 = 2/3x then -2/ 2/3 = x and -2 divided by 2/3 would be -3

Given:
Mean = 45
Standard deviation = 9
Confidence level = 95%.
To find:
The confidence interval.
Solution:
The formula for confidence interval is:
[tex]C.I.=\overline{x}\pm z\dfrac{\sigma}{\sqrt{n}}[/tex]
Where, [tex]\overline{x}[/tex] is mean, z is the z-value at given level of confidence, [tex]\sigma[/tex] is the standard deviation and n is the number of observations.
The z-value at 95% confidence level is 1.96.
Here number of observations are not given. Assume it is 1.
Putting [tex]\overline{x}=45,\sigma=9,z=1.96,n=1[/tex].
[tex]C.I.=45\pm 1.96\dfrac{9}{\sqrt{1}}[/tex]
[tex]C.I.=45\pm 1.96(9)[/tex]
[tex]C.I.=45\pm 17.64[/tex]
It can be written as
[tex]C.I.=[45-17.64,45+17.64][/tex]
[tex]C.I.=[27.36,62.64][/tex]
Approximate the value to the nearest whole number.
[tex]C.I.=[27,63][/tex]
The interval for the middle 95% of snowfall is 27 to 63.

Jesse's store buys phone cases for $8 and marks them up 85%. How much does his store sell them for? Round to the nearest cent.
Answer:
Jesse's store will sell the phone cases for $14.80
Step-by-step explanation:
Cost price of the phone cases purchased by Jesse = $8
He marks them up 85%.
Therefore, selling price of the phone cases = $8 + (85% of $8)
= 8 + ([tex]\frac{85}{100}\times 8[/tex])
= 8 + 6.80
= $14.80
Jesse's store will sell the phone cases for $14.80
