candies did you start with?

Answers

Answer 1
Answer:

Answer:

you started with 6 candies

Step-by-step explanation:

find the sum if 1/2 and 1/4 of the remaining half

1/2+1/4=3/4

therefore 3/4 of the candies has been eaten remaining 1/4 of the candies.

total fractions of candies =1

if 1/4 : 3

then 1: ?

if more, less divides

1÷1/4×3

1×4/1×3

12

there fore the total candies are 12 and since the question asked his much you started with, and you know you started with half of the total, find half of the total

1/2×12=6

I NEED HELP PLZZZ Josh simplified 4x - 8x / 2 and said the answer was -2x. What was Josh's error? What should his answer have been?\

Answers

Hello there, 

This is a trick question Josh did not have an error. If you have 4x-8x in the numerator that becomes a -4x/2.
So then -4x/2= -2x
Josh was not wrong.

I hope this helped!

Could somebody please answer these four questions with simple yet explanatory answers?

Answers

1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10  <--width+width
4+4=8 <---length + length 
10+8=18  <--total perimeter
18 * 9=162in^2  <--multiplied the height +perimeter of base  
Lateral Area=162in^2

2) Same concept as the previous one
 Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2

Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2  
Pooja answered #1 and #2 correct, so I shall make my life easier by answering #3 and #4 :P

#3 tests the concept of surface area. The gift wrap will be covering only the surface of each side. Surface area is all of the outside. Volume is all of the stuff inside.

So the surface area of rectangular prism can be found by the formula:
SA = 2(LW + LH + WH)
SA = 2(9*7 + 7*4 + 9*4)
SA = 2(63 + 28 + 36)
SA = 2(127)
SA = 254 in²

#4 also needs you to find the surface area. 
So the surface area of a triangular prism can be found by this formula:
SA = bh + (\sf s_1 + s_2 + s_3)h
SA = (6.3*2) + (6.3 + 2.5 + 5.2)3
SA = 12.6 + (14*3)
SA = 12.6 + 42
SA = 54.6 cm²

Which answer describes the simpler problems that could be used to solve this story problem? Emily paid a total of $109.95 for 4 pairs of sandals and a pair of boots. Each pair of sandals cost the same amount. The pair of boots cost $29.99. How much did 1 pair of sandals cost?

A.
Subtract the cost of the boots from the total cost. Divide that answer by 4.

B.
Add the cost of the sandals and the cost of the boots. Divide the sum by 4.

C.
Multiply the total cost by 4. Subtract the cost of the boots.

D.
Divide the total cost by 4. Add the cost of the boots.

Answers

A. Take out the cost of the boots since you know how much they are. Then divide by 4 since the 4 sandals cost the same to figure out how much 1 pair of sandals is. :)
