Use the net to find the surface area of the prism

Mathematics
1 answer:
swat323 years ago
4 0
If we were to fold this into a prism, the rectangle on the left would be the base. The short sides of the triangles would fold to meet up with the 5 inch sides of the base. Then the rectangle on the right would fold down and fit between the two triangles, meeting up with the base. Visualizing the shape in 3 dimensions allows us to figure out the lengths of some sides. For example, the short sides of the triangles both equal 5 inches. Also, the long sides of the triangles equal 13 inches and the long side of the base is 8 inches.

The surface area is the area of all the surfaces.

8*5=40
8*12=96
2*(0.5*5*12)=60
13*8=104

Add these up..

40+96+60+104=300 in^2

Tamiku [17]

Julie travelled with 30.5 miler per gallon.

<u>SOLUTION: </u>

Given, On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas.  

On the return trip she traveled 235 miles on 8 gallons of gas.  

We have to find how many miles per gallon did Julie get on the way there?

We know that,

\text { number of miles per gallon }=\frac{\text { total distance travelled }}{\text { total number of gallons }}

Substituting the values we get,

=\frac{192+235}{8+6}=\frac{427}{14}=30.5 \text { miles per gallon }

Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.

Can somebody help me asap?
Oduvanchick [21]

Answer:

44%

Step-by-step explanation:

First, take that pretty figure and align it into complete rows.

It will make 2 full rows plus one block.

1 row is 20% since 100 / 5 blocks is 20.

That's 11 blocks.

11 / 25 = .44 or 44%

3. The population P in thousands of a city can be modeled by the equation
madreJ [45]

Answer:

27 years

Step-by-step explanation:

P is measured in thosands therefore, P will have a value of 120

so it would be...

120=80e^0.015t

80e^0.015t=120

e^0.015t=120/80=3/2=1.5

e^0.015t=1.5

0.015t= In(1.5)

t=In(1.5)/0.015

∴ t≈27.03 round it to 27 years

It would be greatly appreciated if you gave me the brainlest
