Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: N + 9
N is equal to 12 in this equation
12 + 9 is 21.
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is 12(12)= 144
Hope this helps!

Step-by-step explanation:
There is a line whose y-intercept is 8 and whose slope is 10. What is its equation in
slope-intercept form?
Answer:
y = 10x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 10 and c = 8 , then
y = 10x + 8 ← equation of line
Answer:
y = 10x + 8

work out the size angle DEF
Answer:
Step-by-step explanation:
Here, we want to get the value of angle DEF
we have this as ;
Angle DEF = 1/2 * DOF
1/2 * 150 = 75
This is because angle at the center is twice the angle at the circumference

plz help math question
Answer:
y = -2x +20
6x - 5y = 12
Put the value of y in 2nd equation
6x - 5( -2x +20 ) = 12
6x +10x -40 = 12
16x = 12 +40
16x = 52
x = 13/4
Putting the value of x in equation 1
y = -2x +20
y = -2(13/4 ) +20
y = 27/2

Annual snowfall in Anchorage, Alaska, is normally distributed with a mean height of 76 inches and a standard deviation of 4.7 inches. What is the probability this year that it will snow between 71.4 and 80.7 inches in Anchorage?
Using the Empirical Rule, it is found that there is a 68% probability this year that it will snow between 71.4 and 80.7 inches in Anchorage.
What is the Empirical Rule?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, the mean height of 76 inches and a standard deviation of 4.7 inches, hence 71.4 and 80.7 inches is within 1 standard deviation of the mean, that is, there is a 68% probability this year that it will snow between 71.4 and 80.7 inches in Anchorage.

3. Find the measure of the sides of the triangle if the vertices of AEFG are E
(1,4), F(5, 4), and G(1,0). Then classify the triangle by its sides.
The triangle EFG is an isosceles triangle as side EF is congruent to side EG.
How to determine a triangle according to its sides
In this question we have a triangle whose vertices are known. We need to define the figure according to the congruency among its sides. Two sides are congruent when both have the same length. There are three kinds of triangles:
Scalene - Three sides of different length.Isosceles - Two sides of equal length.Equilateral - All sides are of equal length.Sides are formed each pair of vertices. The length of each side can be found by means of Pythagorean theorem:
l = √[(Δx)² + (Δy)²]
First, write the locations of the vertices:
E(x, y) = (1, 4), F(x, y) = (5, 4), G(x, y) = (1, 0)
Second, determine the length of every side of the triangle:
EF = √[(5 - 1)² + (4 - 4)²]
EF = 4
FG = √[(1 - 5)² + (0 - 4)²]
FG = √[4² + (- 4)²]
FG = 4√2
EG = √[(1 - 1)² + (0 - 4)²]
EG = 4
By direct comparison, we conclude that the triangle EFG is an isosceles triangle.
