Step-by-step explanation:
that is a strange question. you will see in a moment why.
I suspect your teacher just wants to do the exercise to have a large volume and then see how often a small volume fits into that large volume.
we can do that quickly:
large volume = 10×2×312 = 6240 in³
small (cube) volume = 12×12×12 = 1728 in³
so, we could put 6240/1728 = 3.611111111... cubes into a volume as the prism has.
now why did I phrase this so strangely ?
because the prism not only has volume but also a shape.
it is a narrow but high container with the small dimensions being 10 in and 2 in.
the cubes have a side (or edge) length of 12 in. that is not compatible with the 10 in and 2 in cubes of the prism.
not a single one cube would fit into the prism.
so, the realistic answer is : 0 cubes.
if it does not matter that the cubes would stand out of the prism, we could simply stack a single file of cubes along the height of the prism :
312/12 = 26 cubes.
so, we could stack 26 cubes inside the height of the prism.
so, I conclude, this is either a trick question (and 0 is the true answer), or there is a mistake in the question.
possibly in the dimensions of either the prism or the cubes.
for example, let's assume the cubes have an actual side length of 2 in (and not 12 in).
then the small (cube) volume is : 2×2×2 = 8 in³
and they will fit into the prism also shape wise.
6240/8 = 780 cubes
so, we would need 780 cubes of that size to fill the prism.
or, as another example, the cubes have a side length of 1/2 in.
then the small (cube) volume = 1/2³ = 1/8 in³
6240/(1/8) = 6240 × 8 = 49,920 cubes
in that case we would need 49,920 cubes to fill the prism.

Answer:
3x+3x+7x+20+7x+20=360
20x=360-20
20x=320
x=16
therefore x=16 so,
7x+20+y=180
but x=16
7(16)+20+y=180
y=180-132
y=48

Answer:
A= 10x^2 + 7/ 2 xy − 3y^2
Step-by-step explanation:
( 1/ 2) (5x−2y))(4x+3y)
= ( 1/ 2(5x−2y)) (4x+3y)
= ( 1/ 2 (5x−2y)) (4x) + ( 1/ 2 (5x−2y)) (3y)
= 10x^2 − 4xy + 15/ 2 xy − 3y^2
= 10x^2 + 7/ 2 xy − 3y^2

=====================================================
Explanation:
Imagine a bucket of water being held up by a rope.
Gravity pulls down on the bucket with a constant force. The reason why the bucket doesn't fall to the ground is because the tension in the rope is holding it up.
More specifically, the force of the rope's tension is exactly matching the force of gravity. So we have equal magnitudes here. However, the force vectors point in complete opposite directions. Gravity points down and the tension of the rope points up. The two opposite directions cancel out to create balance and that's why the object doesn't move. It has velocity = 0 which is considered a constant velocity even though it's not something like 3 m/s.
If the forces acted in the same direction, then the magnitudes would add up to accelerate the object (either downward or upward). However, the bucket stays fixed in place, so it's clear that the vectors must be opposite in nature.
---------------
Now consider a skydiver. At some point of the descent, the skydiver will hit terminal velocity. This is the fastest s/he can fall because the force of gravity pulling down counterbalances perfectly with the upward force of wind/air resistance pushing upward. The air is resisting the downward motion being a form of friction. In this case, the magnitude of the gravitational force is the same as the magnitude of the upward air resistance.
Unlike the bucket of water, the skydiver is of course moving. They are moving at a constant velocity since they cannot accelerate any faster. Hence the name "terminal" meaning "the final or ending velocity". It is when the parachute is deployed that will apply a much greater upward force, which then slows down the downward velocity to allow the skydiver to safely land.
---------------
In both examples, we have a constant velocity happening when the vectors pull in equal amounts but in opposite directions. Think of it like a tug-of-war to keep everything balance. If there is an imbalance of any kind, then acceleration will happen.
Brianna is a waitress in an upscale restaurant. On Friday she waited on 12 groups of customers who spent an average of $186 per group. Her tips averaged 18% of the total amount spent by all the groups of customers that day. What were Brianna's tip income earnings that day?
Given :
Brianna is a waitress in an upscale restaurant. On Friday she waited on 12 groups of customers who spent an average of $186 per group.
Her tips averaged 18% of the total amount spent by all the groups of customers that day.
To Find :
Brianna's tip income earnings on Friday.
Solution :
Total amount of money spent by 12 groups :
P = $ 12×186 = $2232 .
She got tip of 18% of the total amount spent by all the groups of customers.
[tex]T = P\times \dfrac{20}{100}\\\\T= 2232\times \dfrac{20}{100}\\\\T=\$446.4[/tex]
Brianna's tip income earnings on Friday is $446.4 .
Hence, this is the required solution.

A biologist hopes to estimate the proportion of alligators in Florida that are adult. When sampling alligators, the biologist computes the one-proportion Z-interval going from 0.67 to 0.74 at 99% confidence. The margin of error for a 95% confidence interval would be:_____.
Using the z-distribution, as we are working with a proportion, it is found that the margin of error for a 95% confidence interval would be of 0.0008.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
Considering the 99% confidence interval, which has z = 2.575, the estimate and the sample size are given by:
[tex]\pi = \frac{0.67 + 0.74}{2} = 0.705[/tex]
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.74 - 0.705 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]
[tex]0.035 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.575\sqrt{0.705(0.295)}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.705(0.295)}}{0.035}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.705(0.295)}}{0.035}\right)^2[/tex]
[tex]n = 1126[/tex]
Hence, the margin of error is given by:
[tex]M = 1.96\sqrt{\frac{0.705(0.295)}{1126}} = 0.0008[/tex]

b. If 60% of the miles you drive are on the highway and 40% are around town, what
is your overall average miles per gallon?
need work shown if possible im really confused
Answer:
Ok so what it is asking on part A is if your driving 50% on the highway which is 30 miles a gallon and 50% on around the town which is 25 miles a gallon then how many miles a gallon are you getting and the answer for that you need to first find what kind of problem it is and in this case you are working with percents so what you first want to do is multiply 50% to both 30 and 25 which will be 15 and 12.5 then add those together to get you answer now do the same for part B but instead of 50% it will be 60% and 40%.

Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance
