Answer:

see below

Step-by-step explanation:

1. The inverse means take the not of both sides

If it is Saturday, then there is no school.

Inverse If it is not Saturday, then there is school.

The converse flips the then and the if

If there is no school, then it is Saturday.

2.) The first given part is the if, what will happen is the then part

If you are a freshman, then you are required to attend orientation.

3.)

Given: 3x+1=-14 Prove: x=-5

Statements Reasons

1. 3x+1=-14 Given

2. 3x=-15 Subtraction Property of equality ( since we subtract 1 from each side)

3. X=-5 Division Property ( since we divide each side by 3)

Sedbober [7]

Answer:

0.81 hour

Step-by-step explanation:

Given data

Distance= 544.32 miles

Speed= 672 miles per hour.

We know that

Speed= distance/time

Substitute

672= 544.32/time

cross multiply

time*672= 544.32

time= 544.32/672

time= 0.81 hour

When a number is increased by 2.8%, the result is 56. What is the original number to

Sever21 [200]

Answer:

The original number was 54.5.

Step-by-step explanation:

If a number is increased by 2.8%, then it is 102.8% of it's original number.

In mathematics, "of" in virtually all cases means "multiplied by".

Therefore, we do the opposite:

1. Convert to a decimal.

102.8% = 1.028

2. Divide by the decimal.

$56 \div 1.028 = 54.47$

3. Round it to the nearest tenth.

54.47 rounds to 54.5.

I need help on #9. The help would be grateful appreciated.

ELEN [110]

Original Figure:
Length = 15
Width = 5
Height = 10
Volume = Length*Width*Height
Volume = 15*5*10
Volume = 750

New Figure
Length = 3
Width = 1
Height = 2
Each dimension has been divided by 5 (eg: 15/5 = 3)
Volume = Length*Width*Height
Volume = 3*1*2
Volume = 6

The old volume was 750 and it changes to 6
Notice how 750/6 = 125
Which can be rearranged to 750/125 = 6

Answer: if you divide the old volume by 125, then you get the new volume

Note: the new volume is 125 times smaller than the old volume
Put another way, the old volume is 125 times larger compared to the new volume

The fact that 125 = 5^3 is not a coincidence. If you divide each dimension by some number k, then you divide the volume by k^3
