Mrs. Chang's class built a platform for use in a school play. What is the
volume of the platform?
PLEASE HELP!
Answer:
Total Platform = 128 ft^3
Step-by-step explanation:
Volume = Length * Width * Height
Left Volume: 2 ft * 4 ft * 3 ft = 24 ft^3
Mid Volume: 4 ft * 4 ft * 5 ft = 80 ft^3
Right Volume: 2 ft * 4 ft * 3 ft = 24 ft^3
Total Volume = 24 ft^3 + 80 ft^3 + 24 ft^3 = 128 ft^3
Answer:
v = [tex]108^{3}[/tex]
Step-by-step explanation:
I'd start with breaking the platform into two parts, the long flat rectangle and then the bit on top. You'll have to add these together at the end!
_________________
So part one: the long piece
formula: v = lwh
dimensions: 12, 3, 2
plug in: v = 12 * 3 * 2
solve: v = 72^3
_________________
part two: smaller rectangle on top ::
formula: v = lwh
dimensions: 4, 3, 3
plug in: v = 4 * 3 * 3
solve:v = 36*3
__________________
now, we add for the total of the entire shape!
final answer: 72 + 36 = 108^3

A packet of vegetable seeds has a germination rate of
90%. What is the probability that exactly 10 of 12
seeds planted will sprout?
N = number of seeds planted
P = probability of germination
K = number that germinated
Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k
p(10) = (12 10) x 0.90^10 x 0.10^2
P(10) = 0.2310

a bicyclist covered 5/7 of his route and an additional 40 miles. he has yet to cover 118 miles less than 0.75 of his route. how long is his route
The length of the route of a bicylist that has covered 5/7 of his route and an additional 40 miles and yet to cover 118 miles less than 0.75 of his route is 168 miles.
How to form equation and solve for the variable?The bicyclist covered 5 / 7 of his route and an addditional 40 miles.
Let
x = distance of his route in miles
Hence,
distance covered = 5 / 7 x + 40
He has yet to cover 118 miles less than 0.75 of his route. Therefore,
distance not covered = 0.75x - 118
Distance of his route = 5 / 7 x + 40 + 0.75x - 118
x = 5 / 7 x + 40 + 0.75x - 118
x = 1.464x - 78
x - 1.464x = -78
-0.464x = -78
x = 78 / 0.464
x = 168.103448276
x = 168 miles

Find the sum of the first 40 terms of the arithmetic sequence.
14, 4, -6, -16, -26, -36
Answer:
-7240
Step-by-step explanation:
The nth term is -10n + 24.
So the combination of the first and second term would be (-10+24)+(-10x2+24) and this would continue for the first 40 terms so the 24s would add up to 24x40=960. Meanwhile, the -10s would keep adding up so it would be -10-20-30-40.... which you can simplify by making it -10(1+2+3+4) all the way to 40 to make the calculation easier... u can further simplify by making 41 = one pair of numbers so 40+1, 39+2 until you get 21+20 so ur left with -10(20 pairs of 41) so -10(20x41) = -10(820)= -8200.
Add this to your initial 960 so
-8200 +960 = -7240

There are 2 triangles and 6 circles. What is the simplest ratio of triangles to circles?
Hi!
We are asked to find the ratio.
A ratio is a relationship/comparison between two or more numbers based on their numerical value.
We know that, for every 2 triangles there are 6 circles. We can set up our ratio to look like this:
[tex]\cfrac{2}{6}[/tex]
---
(NOTE: there are many different ways to write ratios, including: "x:y", "x to y", or "x/y")
---
The question asks us to write it in simplest form. The fraction [tex]\cfrac{2}{6}[/tex] is NOT in simplest form. It can be simplified to:
[tex]\cfrac{1}{3}[/tex]
This is the ratio in simplest form.

Shen needs to read 2 novels each month
Let N be the number of novels Shen needs to read in M months.
Write an equation relating N to M. Then use this equation to find the number of novels Shen needs to read in 13 months.
Answer:
Equation: N = 2M, Shen needs to read 26 novels in 13 months
Step-by-step explanation:
Given : Shen needs to read 2 novels each month.
i.e. In One month , the number of novels read by Shen = 2
Let N be the number of novels Shen needs to read in M months.
Then , N = 2 M
Thus , the equation relating N to M : N = 2 M
If Number of months = 13 , then put M = 13 in the above equations , we get
N = 2(13) = 26
Hence, the number of novels he read in 13 months = 26.
Jack has a mask collection of 500 masks. He keeps 235 of the masks on his wall. What percentage of Jack's mask collection does he keep on his wall?
Answer:
47%
Step-by-step explanation:
First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.
The sale price of a backpack is $45.00. This is 75% of the original price.
What was the original price of the backpack?
$33.75
$36.00
$56.25
$60.00
Answer:
$60.00
Step-by-step explanation:
75% OF X (original price) = $45
.75x = $45
divide both sides by .75 to isolate X
.75 / .75 = $45 / .75
X= $60
I don't know what it means by an obtuse angle. I have to choose math because I don't see a subject for shapes and stuff.
Answer:
Angle ADE is an obtuse angle.
Step-by-step explanation:
An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).
Answer:
An obtuse angle is anything bigger than 90 degrees because 90 degrees is a right angle, therefore D. ADE would be the answer.
