How do you find the missing length and area of a pyramid only having the volume and height? For example my volume is 225 and my height is 3. What is my area and length? Please explain :)

Answers

Answer 1

The volume of a pyramid is given by:
V=1/3×(base area)×height
suppose the base of the pyramid is square:
volume=225 cubic units'
height=3 units
thus plugging in our values in the formula
225=1/3×(base area)×3
thus
base area=225
hence we conclude that if the base is square then the dimensions will be:
L=√225=15 units
thus the answer is 15 units by 15 units base

The first proposal identifies total costs for materials and labor. The proposed charges add to ...
410.20 +919.60 +9675.00 = 11,004.80
When divided by the number of seats (4250), the per-seat amount is computed to be
$11,004.80/(4250 seats) ≈ $2.5894/seat

The second proposal breaks out charges on a per-seat basis, so those can be added directly to give a per-seat total.
($0.35 +0.75 +1.50)/seat = $2.60/seat

The second proposal is about $2.60 -2.5894 = 1.06 ¢/seat more than the first.

How do you fully learn your times table and division

Answers

Go over them everyday and let someone test you out from the 1x then 2x and etc

There are simple tricks
•For the 0 everything is 0
•For the 1’s it’s always the same number ur multiplying it by so like 1x2 is just gonna be 2
1x3 is 3 and 1x578 is 578 simple as that.
•For your 2s times tables it’s literally just adding the same number twice so let’s say you have 2x7 which is the same thing as saying 7x2 all you have to do is just add the same number twice so it’s 7+7= 14 lets do another so 5x2 =10 so 5+5=10
•For your 3’s here’s a 2 minute video and it’s supper helpful
https://m.youtube.com/watch?v=ONl323NU0ws
•For the 4s times tables here a quick link https://m.youtube.com/watch?v=UOGuJRzYv0A
•For the 5s times tables it’s really easy not sure if you need help with that one
•For the 6s

•For 7s
https://m.youtube.com/watch?v=hau8eYZV0t8
•For 8s
https://m.youtube.com/watch?v=-C-e33iVBTM
•For 9s
https://m.youtube.com/watch?v=puFOpCt1_DY
•For 10s all you have to do is do the same trick as for the 1s but put a zero behind the number so 10x7 is 70 and 10x8 is 80 and 10x9 is 90

There is only so many tricks you can learn so just study it a-little bit because multiplication is veryyyy important.
Multiplying is just adding the same number how ever many times
So let’s say you need to add the number 2 in 9 different times instead of saying 2+2+2+2+2+2+2+2+2=18 you can just simply say 2x9=18 simple Right?

A factory makes 12 bottles every 2 minutes. The factory makes bottles for 8 hours each work day. Enter a whole number to represent the fewest number of work days the factory will need to make 28,000 bottles.

Answers

It will take 15 days to manufacture 28000 bottles.

We have a factory makes 12 bottles every 2 minutes and makes bottles for 8 hours each work day.

We have to determine the number of days it will take to make 28000 bottles.

What is Unitary Method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to question, we have -

Number of bottles manufactured in 2 minutes = 12.

In 8 hours = 8 x 60 = 480 minutes = 2 x 240 minutes.

Number of bottles manufactured in 1 day = 8 x 240 = 1920 bottles.

Number of days needed to make 28000 bottles = 14.58 = 15 days.

Hence, it will take 15 days to manufacture 28000 bottles.

Answer: No, Diego cannot fit 65 smaller cubes into the large box. There will be 5 cubes that cannot be put in,

No, Diego cannot fit 65 smaller cubes into the large box. There will be 5 cubes that cannot be put in.

What is volume?

Volume in math is the amount of three-dimensional space occupied by an object, substance, or closed surface. Volume can be measured by multiplying the length, width, and height of an object or by counting the number of unit cubes it contains.

Given that, Diego has a large box that is 4 feet high, 3 feet wide, and 5 feet long, we need to determine whether he can fit 65 smaller boxes that each have a volume of 1 cubic foot in the large box,

For determining the same, we will find both volume and compare,

Volume of the large box = 4 x 3 x 5 = 60 ft³

Volume of a cube = 1 ft³

Total number of cubes = 1 x 65 = 65 ft³

Since, both the volumes are equal,

Therefore,

He cannot fit 65 smaller cubes into the large box, as he will be left with 5 boxes out of the box.

Hence, Diego can not put 65 boxes in the larger one.

Kristen invests $5,745 in a bank. The bank pays 6.5% interest compounded monthly. How long must she leave the money in the bank for it to double? Round to nearest tenth of a year.

Answers

To solve this we are going to use the compounded interest formula: [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where
[tex]A[/tex] is the final amount
[tex]P[/tex] is the initial investment
[tex]r[/tex] is the interest rate in decimal form
[tex]t[/tex] is the time in years

We know that initial investment is $5,745, so [tex]P=5745[/tex]. We also know that Kristen wants his investment to double, so [tex]A=2*5745=11490[/tex]. Now, to convert the interest rate to decimal form, we are going to divide the rate by 100%: [tex]r= \frac{6.5}{100}=0.065 [/tex]. Since the interest is compounded monthly, it is compounded 12 times per year: therefore, [tex]n=12[/tex]. Now that we have all the information we need, lets replace the values in our formula and solve for [tex]t[/tex]:
[tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
[tex]11490=5745(1+ \frac{0.065}{12})^{12t} [/tex]
[tex] \frac{11490}{5745} =(1+ \frac{0.065}{12})^{12t}[/tex]
[tex]2=( \frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=ln(\frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=12tln(\frac{2413}{2400} )[/tex]
[tex] \frac{ln(2)}{12ln(\frac{2413}{2400} )} =t[/tex]
[tex]t=\frac{ln(2)}{12ln(\frac{2413}{2400} )}[/tex]
[tex]t=10.7[/tex]

We can conclude that she must leave the money for 10.7 years in the bank for it to double.

NEED HELP ASAP!!! Which graph represents the given inequality? 3x -7y < -21

Answers

Hello there, and thank you for asking your question here on brainly.

Short answer: The first graph, A.

Why?

The equation 3x - 7y < -21 is a dotted line that passes through -7 on the axis. Therefore, the correct answer is A.

Hope this helped you! ♥

Answer:

Step-by-step explanation:

Given the inequality

3x —7y <—21

Make y subject of formulae to know the slope and intercept on y axis

—7y < —3x — 21

Divide through by -7, note the inequalities sign will change since we are dividing with a negative

Then,

y > 3x/7 + 3

Then, the intercept is 3 and the slope is 3/7 when compared to equation of a line y = mx + c

We know that

y is greater than 3x/7 + 3, so the upper part should be shaded since y is greater than 3x/7 + 3

Then, option B and C are wrong since the below is shaded

Let find the intercept on the x axis to know the answer between A and B

I.e. when y = 0

3x —7y <—21

3x < —21

x < -7, then, line should pass through the negative of x and not positive x

So, the first option (A) is correct

C. 5/6 and (-3, 1)

Answers

Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.

so what we know is that 15 is the diameter

However the formula to find the area of a circle is A=[tex] \pi [/tex]r²
So to convert the 15 in diameter to a radius you have to do 15÷2,which is equal to 7.5

Now we know that the radius is 7.5.
So what we do now is A=[tex] \pi [/tex]7.5²
Then after we find what 7.5² is we get A=[tex] \pi [/tex]56.25
Then what we do is 3.14×56.25, because pi= 3.14.
So when we do 3.14×56.25, we get 176.625
So the answer is A= 176.6 in²
