If your good in math please help me
Feliz [49]

Answer:

350.82

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (lw):

7.21*14=100.94

The triangle's area (\frac{1}{2}bh):

\frac{1}{2} (6)(8)

\frac{1}{2} (48)=24

Now add up all the sides. (3 Rectangles, 2 Triangles.)

100.94 + 100.94 + 100.94 + 24 + 24

=350.82

The total surface area is 350.82 cm squared.

Convert 80 km per hour and 120 km per hour to meters per second​
Burka [1]

hi brainly user! ૮₍ ˃ ⤙ ˂ ₎ა

⊱┈────────────────────────┈⊰

\large \bold {ANSWER}

  • \large \boxed { \large \sf \green{ 80 km/h = 22.22 m/s }}
  • \large \boxed { \large \sf \green{ 120 km/h = 33.33 m/s }}

\large \bold {SOLUTION}

The first thing we must do is convert kilometers to meters. We will do this by multiplying by 1,000, since 1 km corresponds to 1,000 meters.

  • 80*1000 = 80,000
  • 120*1000 = 120,000

Now that we've done that, let's divide the values by 3,600, because an hour is 60 minutes, and each minute is 60 seconds, so 60*60 is 3,600.

\frac{80.0\not0\not0}{3.6\not0\not0}=22.22

\frac{120.0\not0\not0}{3.6\not0\not0}=33.33

Hence, 80 km/h = 22.22 m/s, 120 km/h = 33.33 m/s

Order the set of integers from least to greatest 5, -3, -12, 9
Sauron [17]

Answer:

-12, -3, 5, 9

Step-by-step explanation:

ok. So the numbers are 5, -3, -12, and 9.

In these numbers, there are 2 negatives. They are -12 and -3.

In negatives, the bigger the number is, the number is smaller.

So we first put

-12, -3 as our 2 first. Then the other ones are 5 and 9.

and you obviously know that 5 is less than 9. try it out. 9-5 =4 which is positive

So then you put 5, 9

And our full answer is

-12, -3, 5, 9
