Answer: Hey! Since the other answer is obviously wrong. Here is the actual answer! (from Khan Academy) .
Step-by-step explanation:
The slope is 3.
Change in y = + 3
Change in x = +1
So, it is not 1/3 but it is 3/1 which is technically 3.
Here is the formula!:
Slope = rise/run = Change in y / change in x.
Always put the y above the x!!! :)
The price of a car is £15400 before it is reduced by 8%.
How much does it cost after the reduction?
Answer:
14168
Step-by-step explanation:
15400 / 100 x 8 = 1232
1232 = 8%
15400 - 1232 = 14168

Step-by-step explanation:
Solve the following SYS
y = 6x + 5
y= 4x - 11
This is the second question
Answer:
x=-8, y= -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
Since both equations are equal to y, we can set them equal to each other
6x + 5= 4x - 11
Subtract 4x from each side
6x-4x+5 = 4x-4x-11
2x+5 = -11
Subtract 5 from each side
2x+5-5 = -11-5
2x = -16
Divide each side by 2
2x/2 = -16/2
x = -8
Now we need to find y
y = 6x+5
y = 6(-8) +5
-48+5
-43
Answer:
x = -8 y = -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
6x + 5 = 4x - 11
2x = -16
x = -8
y = 4(-8) - 11
y = -32 - 11
y = -43

A pizza parlor charges $18 for a plain pizza and charges $0.75 for each additional topping.
Which of the following best models the cost of a pizza?
y = 18x +0.75
y = 13.5x + 18
y = 180.752
O y = 0.75x + 18
Answer:
the last one
Step-by-step explanation:
well you have 18 pizzas total, and each topping is 0.75. so let's say u want two toppings you would do 75 ×2 and so on, you would label the question
Y= 0.75x + 18
What type of skew does this graph have?
Answer:
Negative skew; skewed right.
Step-by-step explanation:
It is a negative skew, because the peak of the graph is located towards the left (5- 9, respectively). The skewed is on the right, for the tail stretches out to the right of the graph (10-14 all the way to 25 - 29, respectively).

Find the length of the base of the following pyramid, given the height of the pyramid is 221 meters and the angle of elevation of the base of the pyramid is 62°. Round to the nearest whole number.
An image of a square pyramid is shown with a right triangle embedded inside it. The face is at an incline of 62 degrees. The height is labeled 211, and the corner of the right angle is marked with a letter P.
75 meters
189 meters
235 meters
416 meters
Answer:I believe it would be answer choice, 235 meters
Step-by-step explanation:
I’m not super good at explain but, the height and incline both go at the right slope when they interact. Have a good day, hope it helps.
The length of the pyramid's base would be:
C). 235 meters
Find the length of the baseGiven that,
Height of the pyramid [tex]= 221[/tex]
Elevation/angle of the base [tex]= 62[/tex]°
Employing the trigonometric function,
Tan 62 [tex]= 221/[1/2 base][/tex]
⇒ Base [tex]= (2[/tex] × [tex]221)[/tex][tex]/Tan[/tex][tex]62[/tex]
[tex]= 2[/tex] × 221/[tex]1.88[/tex]
[tex]= 235.10[/tex]
Thus, option C is the correct answer.

A cylinder has a volume of 371.776 cubic centimeters. The diameter of the cylinder is 8 cm. What is the height of the cylinder? (Assume = 3.14)
Cylinder volume formula:
V=πr^2h
Substitute given values into the formula
Note: use 3.14 for pi
Diameter is twice the radius, so if diameter is 8 then radius is 4
371.776 = (3.14)(4^2)h
Use h for height because we don't know the height
Okay, so let's try to get the h by itself on the left side of the equation
So begin by getting rid of 3.14 by dividing it by both sides
371.776/3.14 = 118.4
3.14/3.14 = 1 (don't put 1, just remove the 3.14 from the right side)
So now we have:
118.4 = 4^2(h)
Now we can get rid of 4^2
Start by actually squaring it and then divide it from both sides
118.4 = 16(h) (4^2 = 16)
118.4/16 = 7.4
16/16 = 1 (dont put 1, just drop it)
So now we have
7.4 = h
Now we have h by itself! So h = 7.4
let's test it by putting it in the cylinder volume formula
V = πr^2h
371.776 = (3.14)(4^2)(7.4)
371.776 = (3.14)(16)(7.4)
371.776 = 50.24(7.4)
371.776 = 371.776
7.4 is your answer, if you have any questions, feel free to ask
Determine the center and radius of the following circle equation:
x² + y² - 10x + 20y + 89 = 0
Answer:
The center is ( -5, -10) and the radius = 6.
Step-by-step explanation:
Convert the equation to standard form by completing the square;
x^2 + y^2 - 10x + 20y + 89 = 0
x^2 + y^2 - 10x + 20y = -89
x^2 - 10x + y^2 + 20y = -89 Completing the square:
(x + 5)^2 - 25 + (y + 10)^2 - 100 = -89
(x + 5)^2 + (y + 10)^2 = -89 + 125
(x + 5)^2 + (y + 10)^2 = 36
Comparing this to the standard form:
( x - h)^2 + (y - k)^2 = r^2
- we see that the center is ( -5, -10) and the radius = 6.
IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. If a certain statistician has an of 122 , what percent of the population has a lower IQ?
A. 47%
B. 93%
C. 22%
D. 99%
E. 7%
Answer:
B. 93%
Step-by-step explanation:
Find the z-score:
z = (x − μ) / σ
z = (122 − 100) / 15
z = 1.47
Find the probability using a calculator or z-score table.
P(Z < 1.47) = 0.93

Help asap please ! Please explain too
Answer:
D) 35
Step-by-step explanation:
angles that are opposite are equal, so the 45 degree angles is in th triangle too. angles on a straight lines are equal to 180, so 180 - 80 = 100.
So far we have two of the angles, 100+45=145
Angles in a triangle are equal to 180, so 180-145 =35
vertically opposite angles are the same, so the ? is 35 degrees
Hope that helps
Why are the units of area squared? How does this help us remember the formula for area of a circle?
