Answer 1

Answer:

Volume = 2880m²

Surface area = 1632m²

Step-by-step explanation:

The prism shown is a triangular prism

The volume of the prism can be found by multiplying the area of the base by the length of the prism

The base being a triangle.

The area of a triangle can be calculated by using this formula

[tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The base length of the particular triangle is 12 m and the height is 16

That being said we plug in the values into the formula

[tex]A=\frac{12*16}{2} \\12*16=192\\\frac{192}{2} =96[/tex]

Hence the area of the base is 96 square meters

Finally we multiply the area of the base by the length of the prism ( which is 30 m )

So volume = 96 * 30

96 * 30 = 2880

Hence the volume of the triangular prism is 2880m²

Now to find the surface area

Kindly check the image below for information on the formula for surface area of a triangular prism

Formula = [tex]SA=bh+L(s_1+s_2+s_3)[/tex]

where b = base length

h = height of base

L = length of prism

S1 also = base

S2 = base height

S3 = slant height of base

The shown triangle has the following dimensions

b = 12

h = 16

L = 30

S1 = 12

S2 = 16

S3 = 20

Now that we have identified each dimension, we plug in the values into the formula

[tex]SA=16*12 + 30(12+16+20)\\16*12=192\\30*12=360\\30*16=480\\30*20=600\\600+192+480+360=1632\\SA=1632m^2[/tex]

So we can conclude that the surface area of the triangular prism is 1632m²

19. A cone has a diameter of 36 meters and a slant height of 24 meters. What is the height of the cone to the nearest tenth?
24 m
36 m

Answers

9514 1404 393

Answer:

15.9 m

Step-by-step explanation:

The radius (18 m) and the slant height form one leg and the hypotenuse of the right triangle that has the cone height as the other leg. The Pythagorean theorem tells you the height (h) is ...

18² + h² = 24²

h = √(576 -324) = √252

h ≈ 15.9 . . . . . meters

The height of the cone is about 15.9 meters.

Answer:

x = 13 cm

Step-by-step explanation:

The figure given is a square.

Area of the given square (A) = 169 cm²

Formula for area of a square is:

A = s²

Where,

s = x

Thus:

169 = x²

Take the square root of both sides

√169 = √x²

13 = x

x = 13 cm

Jim bought some nice running shoes for $216. The sales
tax is 6.5% and he is paying cash with bills only because
he doesn't have any change. What is the least amount
he should give the cashier?

Answers

Answer:

I believe the answer is $ 231.00.

Step-by-step explanation:

I might be wrong, but please don't hate me if I am!!

First I found the sales tax of the nice running shoes by multiplying the price of the shoes by the sales tax:

216 * 6.5% = 14.04

Then I added the sales tax to the price of the nice running shoes:

$ 216 + $ 14.04 = $ 230.04

Since Jim doesn't have any change and can only pay in cash, you would round $ 230.04 to the nearest dollar:

$ 230.04 is rounded to $ 231.00 :D

A special CPI is constructed to measure the variation of these products, so that coffee and bread have a weight of 0.35 of the total and egg, ham and cheese 0.1 of the total. variation of the CPI?

Answers

9514 1404 393

Answer:

The CPI increased 3.42% in Month 2.

Step-by-step explanation:

In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.

Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:

pct change = ((new value)/(old value) -1) × 100%

Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.

9 weeks at least to have at least 50 dollars.

Step-by-step explanation:

Well 6 dollars each week and to get AT LEAST 50 dollars you need to save for 9 weeks.

Well 9*6=54

If you do it for 8 you’d only get 48 which is not at least 50 but 54 is.

So 9 weeks is the final answer.

50≤54
