Answer:
124.16 cubic meter of clay will be used to create all the pyramids
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids
3 * BH/3 = BH
Substituting the given values in above equation, we get -
15.5 * 5 = 77.5 cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids
2 * BH/3
2* 10 * 7/ 3
46.67 cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid = 77.7 + 46.67 = 124.16 Cubic centimeter

Determine the measures of the angles if they are both vertical and supplementary.
Answer:
90, 90
Step-by-step explanation:
Since the two angles are vertical, it means that they must have the same measure. Because they are supplementary, that means they add to 180. Thus, the two angles must be 90 and 90.

-8x + 3y = -33
y = -5x + 35
Answer:
x = 6 y = 5
Step-by-step explanation:
-8x + 3y = -33
y = -5x +35
-8x + 3(-5x + 35) = -33
-8x - 15x + 105 = -33
-23x + 105 = -33
-23x = -138
x = 6
-8(6) + 3y = -33
-48 + 3y = -33
3y = 15
y = 5

Answer:
1. you answered correctly :)
2. how many 1/4's go into 12? in other words multiply 12 and 4 to get 48/4
3. Draw a diagram of 1/5ths until it equals 15 (you'll need a total of 75 boxes)
4. the problem is 18z=72 so you need to divide 72 and 18. 72/18=4. therefore z equals 4.
5. make up a division problem that has the answer of 8. for example 24/y=3. y will equal 8. and then use a tape diagram for that.
6. make up a multiplication problem that has an answer of 8. for example 3y=24. y will equal 8. and then use a tape diagram for that.
7. Meghan is correct. when you have y divided by two you need to do the opposite and multiply both sides by two. Meredith was incorrect because she switched the division and multiplication signs completely which is not what you are supposed to do.
Step-by-step explanation:
I hope this helped :) (the only thing you could write down word for word is #7. for 1-6 just read what i have to say and follow the directions and it should help) have a great day!!!!
I will solve these equations algebraically.
Here you are:
1. 30= 5w
Divide each side by 5.
30÷5= 5w÷5
6 = w
∴ w= 6
To check,
30=5w
Substitute w for 6
30= 5 x (6)
30= 30
LS= RS
(You were correct, great job!)
2.
12 = x÷4
Multiply each side by 4.
12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.
48= x
∴ x=48
Checking:
12= 48÷4
12= 12
LS=RS
3.
y÷5=15
Multiply each side by 5.
y÷5 x 5= 15 x5
y =75
∴y=75
Checking:
Substitute y for 75.
y÷5=15
75÷5=15
15=15
LS=RS
4.
18x=72
Divide each side by 18.
18x ÷ 18= 72÷18
x = 4
∴x= 4
Checking
18x=72
18(4)=72
72=72
LS=RS

Which is NOT a line of symmetry (please help)
Answer:
3
Step-by-step explanation:
The line 3 is not a line of symmetry.
What is Line of Symmetry?Line of symmetry of a figure or a shape is the line which divides the figure or shape in to equal and symmetrical parts.
This line is also called as axis of symmetry.
It is sometimes also called as mirror line since the line divides in to parts which looks like mirror images.
Given is a shape of a triangle.
There are 4 lines drawn.
Of these, 3 lines are drawn from a vertex of the triangle to the middle point of the opposite side, which divides the triangle in to two equal triangles.
So these lines are lines of symmetry.
But line 3 does not divide the triangle in to equal parts.
So it is not line of symmetry.
Hence line 3 is not a line of symmetry.

There are 4 green marbles and 7 silver marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a green marble?
7/11
4/11
4/7
7/4
Answer:
4/11
Step-by-step explanation:
there are 4 green out of 11 total
Answer:
B.
Step-by-step explanation:
First, you will need to find out how many marbles there are total, which is 11. After doing so, you are able to eliminate two of your answer choices already (C. and D.). Next, identify how many green marbles are in there, which is 4. You are able to identify that A. can be eliminated as well. With you finding probability, the total amount will be on the bottom. So, you can see that there is a 4/11 or about 36% chance that a green marble will be picked.
Hope this helps! :)

The range is 10 so i think in this situation the variability is high becaue 10 miles is a lot more than 2 miles or 0 miles

No, even though the mode is 6 it makes more sense to use the medain or mean to get as close as posible to about how much she rides each day

Answer:
Gotcha!
Step-by-step explanation:
I know this is a day late and you probably have done it, but...The earnings for the first 40 hours are $9.20 x 40 = $368.00 (it’s just 368 but with unnecessary zeros, which you don’t have to add, by the way, this answer is g00gle approved.)
The rate for each after after 40 is $9.20 x 1.5 = $13.80 <— again, you could also put 13.8, since the zero is unnecessary. They both mean the same thing. 13.8 = 13.80 the difference is one has a zero and the other doesn’t.
Therefore, the amount Mr. Evans earned for the extra 1.75 hours is $16.1 (16.10), You added the two amounts to find that Mr Evans earned $384.10
368.00 + 16.10 (also g00gle approved)
You learned that Mr. Evans earned 384.10 last week. (Or whatever answer choice that corresponds/relates to the question.
