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)=
50 - (10) + (15) =
40 + 15 =

Answers

Answer:

Step-by-step explanation:

The equation has one solution.

6(x+2)=5(x+7)

6x+12=5x+35

6x+12-5x=35

6x-5x=35-12

x=23

Therefore, the equation has ONE solution.

there is only one solution to the equation. it is x=23

I need help with Part A and B

Answers

Answer:

Part A) 700 Snack Bags

Part B) [$]1225.00

Step-by-step explanation:

Pretzels and cheese puffs make up 30% (0.30) of the sales which means 210 is 30% of the total bags they sold. You could set up a ratio like this where 1 represents 100%:

210/.30 = x/1

If solved out, you find there are 700 bags total and you can check it by finding that 210 is 30% of 700.

Part a)700
Part b)1225$

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

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
