Answer:
L = 324 cm²
S = 359.1 cm²
Step-by-step explanation:
Lateral surface area of a triangular prism is given by,
Lateral surface area = Perimeter of the triangular base × Height
= (9 + 9 + 9)×12
= 27 × 12
= 324 cm²
Surface area area of the triangular prism = Lateral area of the prism + Area of the triangular bases
= 324 + [tex]\frac{1}{2}(Base)(Height)[/tex]
= 324 + [tex]\frac{1}{2}(9)(7.8)[/tex]
= 324 + 35.1
= 359.1 cm²

Please answer correctly !!!! Will mark Brianliest !!!!!!!!!!!
Answers
Step-by-step explanation:
since they are in order points p and q are in the middle and points O and R are on the end so they say that OR=36 since you don't know the exact lengths of all of the lengths in the middle from O to R then you multiply 5,6 and 1 by x and add
5x+6x+1x=12x
so then the whole length is equal to the ratio of 12x and also 36 so set those to equal each other
12x=36
x=3
so that is just the ratio and since they are asking for the length of O to Q that means that it is just 5x+6x=OQ
11x=OQ
insert x=3
33=OQ

The cafeteria serves pizza every 10 days and corn every 4 days. If they are serving pizza and corn today, in how many days will they serve them together again?
Answers
Answer:
Well it would be 100 days
Step-by-step explanation:
Because they had pizza every ten days and if you add 5 days a week that's 50 days they sell pizza. If your talking corn they sell it every 4 days times 5 days a week that's 20 days of corn. Then you do 50 x 20 and then you get 100 days of pizza and corn, so it would be 100 days before they sell pizza and corn together again!

Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answers
Answer:
$16
Step-by-step explanation:
$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:
4 x 4 = 16
And you'd get your answer, since 4/4 equals 1 whole.

Answers
Answer:
Roberto paid $7.43 cents.

If you don't know how to times a decimal between a decimal, you can see how much money is per pound than times that by 4.5.

If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?
Answers
Answer:
7%
Step-by-step explanation:
since the formula says si=ptr/100
so we have to separate r which gives us r =(i ×100)/(p×t)
now putting the values (980×100)/(7000×2)
=7
therefore the rate of interest is 7%

Step-by-step explanation:
So what i did is times 5 by 3 to get 15 right?
And then you have 3 days left over so to find out how much it costs per day i divided 6.26 by 5 days and got 1.25
so i times 1.25 by the extra 3 days
which you get 3.25
and with the other 15 days you just times 6.25 by 3 because we already know every 5 days is 6.25 if this makes sense to you
