Answer:
Megan added 4 rocks.
Step-by-step explanation:
We know this because if the box had 8 rocks in it intially and it now has 12 rocks, we know that Megan added 4 rocks. Since, 8+4= 12 or 12-8=4
Equation form:
r = how many rocks Megan added
8+r=12
12-8=4
r=4
Megan added 4 rocks.

Answer:
D. 64º and 90º
Step-by-step explanation:
All triangles' angles add up to 180º.
A right triangle must have an angle that is 90º and it gives you that one is 26º so all you have to do is add those together and subtract that from 180º to find the last angle.
180 - (90 + 26) = 64º
So the two other angles of the triangle would be 90º and 64º.
The prism below is made of cubes that measure 1/2 of an inch on one side. What is the volume?
Answer:
the answer is C. 5 cubic in
Step-by-step explanation:
V = LWH
length is 2 (1/2 in)
width is 5 (1/2 in)
height is 4 (1/2 in)
V = (2/2) (5/2) (2)
V = 1 * 5/2 * 2
V = 5 cubic in
how do I round 8164 to the 4 decimal point?
Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:
8164.45678
In this case, the number rounded to the 4th decimal point (ten thousandths) would be
8164.45680
Because the digit after the 7 is 8, we should round the "78" part to "80".
These two rules will help:
5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)
4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)
Hope this helps! :)

Volume of a sphere -
where r is the radius.
A cylinder has radius x and height h.
3x
A hemisphere has radius
2
r: h= 4:9
Prove that the cylinder and the hemisphere have the same volume.
[4marks]
The volume of hemisphere is equal to the volume of the cylinder and the volume is equal to the 9/4× π×x³.
From the given, the volume of the sphere with radius r,
Volume of sphere = (4/3)πr³
The volume of the cylinder with radius x and height h,
Volume of cylinder = π×r²×h
= π×x²×h
The ratio of the radius and height (x:h) = (4:9)
the height of the cylinder is h= (9x/4)
Volume of the cylinder = π×x²×(9x/4)
= π×x³×(9/4)
The hemisphere radius, r = (3x/2)
Volume of hemisphere = 1/2 (Volume of sphere)
= 1/2 (4/3 × π×r³)
= 1/2 (4/3 × π ×(3x/2)³) (where r= (3x/2))
= (9/4×π×x³)
Thus, the volume of cylinder and the volume of hemisphere is same and is equal to 9/4×π×x³.

Answer:
x = 37.5
Step-by-step explanation:
The easiest way to solve this is to realize that the bottom triangle is a an Isosceles triangle, with the upper angle being equal to 180 - 75 degrees. That gives us the number 105°
Because it's an Isosceles triangle, we can simply say that the bottom angles, including the one we want to calculate are equal and both add up 105 (again, because the angles in a triangle add up to 180, and we know the top one is 105).
That gives us:
(180 / 105) / 2
= 75 / 2
= 37.5
1. What is the solution to the equation 4(x+3)=24
x=5.25
x=3
x=6.75
x=6
Answer:
x = 3
Step-by-step explanation:
Your first step is to divide each side by 4. This would give you x + 3 = 6. Now, all you have to do is subtract 3 from the left side to move it to the right. This would give you the final answer of x = 3.
Answer:
x = 3
Step-by-step explanation:
4(x + 3) = 24
First we want to isolate the binomial x + 3 by dividing both sides by 4.
x + 3 = 6
Now, subtract 3 from both sides.
x = 3
This is your answer.
Check your answer by plugging x = 3 back into the equation.
4(x + 3) = 24
4(3 + 3) = 24
4(6) = 24
24 = 24
Your answer is correct.
Hope this helps!

Stacia walked a total of 30,375 feet. If 2 miles is 10,560 feet, how far did Stacia walk in miles?
Answer:
62
Step-by-step explanation:
Answer:
I believe the answer is 5.8 miles
Step-by-step explanation:
I believe this is the correct answer, although it is possible I am wrong.
This is how I solved this problem:
I divided 10,560 feet by 2, which equals 5280 feet in a mile
Then I divided 30,375 feet by 5280 feet to get 5.7528409
Since there is no way this is the correct simplification, you need to round to the nearest tenth.
5.7528409 is about 5.8 miles
