Answer:

Step-by-step explanation:
In order to find what score Alex must earn to have an average of 86 on all his tests, we need to first note what the formula to find the average of a data set is.

What the formula means is that we have to add up all the values then divide by the total number of values.
Let's represent our unknown number as
.
(since we want AT LEAST an 86).
Let's solve this inequality for x.
So, Alex must score at least an 87% on his next quiz to have an average of 86%.
Hope this helped!
We know that one regular hexagon is consist of the six equilateral triangles.
One of this is ΔAFM every angle in this triangle worth 60°, according to this
∡AFM=60°.
ΔABC is isosceles triangle with angle ∡ABC=120°, because every interior angle in regular hexagon worth 120°.
Angles ∡BAC=∡BCA=30°. Total sum of angles in one triangle is 180°.
∡ACF≅∡BCA=30° at the end we can conclud that angle ∡FAC=90° WHY?
Good luck!!!
Answer:

Step-by-step explanation:
the line only passes through the y-intercept once.
Answer:
2
Step-by-step explanation:
as H=20 and W=10
So H=constant.(W)
H=2(10)
H=20
So constant is 2
The question is incomplete. The complete question is :
Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below. What is the total number of cubes that Georgia needs to exactly cover the bottom of the box with a layer one cube deep?
Solution :
It is given that :
There are small cubes that has a dimension of 4 in x 4 in x 4 in.
There is also a box which has a dimension of 24 in x 20 in x 12 in.
We need to find out how many small cubes will Georgia need to cover the bottom of the box.
So, we need to find out the surface area of the one cube and the box.
Therefore, the surface area of one cube = side x side
= 4 inch x 4 inch
= 16 square inches
Similarly the area of the box can be find by = length x breath
= 24 in x 20 in
= 480 square inches
Therefore, dividing the area of the box by the area of the cube, we get

= 30
So Georgia will require exactly 30 cubes to cover the bottom of the box with a layer of one cube deep.
