Step-by-step explanation:

1 - 12 (not writing the question number but all the answers are in order)

-15273. i dont know-38376-200-3150-4110 i dont know120-60

13 - 22 Basically if the number is an absolute value, (by the way a number is an absolute value if it is in these lines: | |) then that simplifies to the positive of that number, always as long as it's inside the two lines.

For question number 3 you would add 24+13+38. And that would give you 75. Making the fraction 75/100, in simplest form it would be 3/4. So the answer for number 3 is 3/4

For number 4: you add 0.5 and 3/10 together, but you can’t add a decimal and a fraction so we will convert the decimal to a fraction, 0.5 is equivalent to 1/2 so we will do 1/2 + 3/10. To add you have to find the most common multiple which would be 10. So now the equation is 5/10 + 3/10. Now all you have to do is add the numerators so 5/10+3/10=8/10. 8/10 in its simplest form is 4/5. Your final answer should be 4/5.

She got 3 extra credit questions correct and recived 5 points for each. What is the total number of points she gained or lost overall

Answers

If I’m right it’s 15 points she gained and 10 points she lost if you combine them it’s 25 points

50 - (5•2)+(5•3)=

Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.

Answers

Answer:

297 is the surface area

Step-by-step explanation:

Ok this problem is very simple.

First lets define some equations.

Area of a triangle: A = 1/2BH

A = Area B = Base H = Height

This equation works for right triangles only.

(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).

Area of a square: A = BH

Surface area equals all the areas of each side added together.

First lets find the area of one of the triangles.

We know 11 is the base and 8 is the height but the triangle isn't a right triangle.

To make it a right triangle divide the base by 2 so 11/2.

You will get 5.5.

Now find the area!

A = 1/2BH

A = 1/2(5.5)(8)

A = 1/2(44)

A = 22

So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).

22(2)=A

44=A

44 is the area of one side of the pyramid but there are 3 other sides (not including the base).

So just do:

44+44+44+44 = A

176 = A

Surface area for the triangles is 176!

Now we must find the area of the square.

A = BH

A = 11(11)

A = 121

Total surface area is all the areas added together so it's:

121+176=A

297

Use mental math to find the sum.
432 + 250

The rabbit population in a certain area is 500% of last year's population. There are 1,300 rabbits this year. How many were there last year?

Answers

There were 260 rabbits last year.

We know that last year was the original population as 100%. The population is now 5 times higher, as 100% x 5 is 500%.

To find the original rabbit population, we would then divide this years population of 1300 by 5, to get 1/5 aka 100% of the population. This number is 260

500/100=5
1300/5=260

260 rabbits hope this helps
