Answer: Additive Inverse of 17 = -17

The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -17?" or "What is the additive inverse of negative 17?" is 17. Since the additive inverse of 17 is -17, additive inverse is also known as the opposite number.

liraira [26]

Answer:

Step-by-step explanation:

You need to multiply 14 x 220%

220% = 2.2

So 14 * 2.2 = 30.8

Another way to think of it would be: 100% of 14 = 14

So 200% would mean you need to double that, which would be 28

Then the final 20% would add 2.8

Add 28 + 2.8 = 30.8

Plz help ASAP which choice is it and why ?

Delicious77 [7]

Answer:

i think it would be choice D

Step-by-step explanation:

this would be because the 20 is 19.8 tons rounded up, the (1.1) is the increase of the original amount plus the 9.8 rounded up, and the (1.05) is the increase by 5.1. the reason why they multiply these like 20(1.1)(1.05) is because each number in the parenthesis is the increase, when you multiply something by 1.1 it will give you it's 100% + the 10% growth, same goes for the 1.05 which will give you the 100% + the 5% of 20(1.1)

in other words if you just multiplied by .1 you would only get 10% of what you're seeking while if you multiply by 1.1 you would get the 110%. the 1 is 100%, and the extra percentage you seek is the decimal (number behind the dot) that follows

PLEASE HELP! Find the median of the stem and leaf plot

nataly862011 [7]

Answer: 20

Step-by-step explanation:

Median means number in the middle

eliminate largest then smallest then next largest then next smallest etc...

do that until you get one finale number. Doing that to this leaf plot will end up with 19 and 21. If you have two numbers you add both of them and divide by 2. doing that will give you the number in between those two numbers or 20 in this case.

tiyleah has a cousin fantasia in france . both families recently bought new cars and the two girls are comparing how fuel effici

Kay [80]

Answer:

Fantasia's family's car is more fuel-efficient.

Step-by-step explanation:

Given that, Tiyleah's family's car is getting 40 miles per gallon, and Fantasia's family's car uses 7 liters per 150 km.

The comparison can be done by observing the distance traveled by the cars in an equal amount of fuel. The car which covers more distance in an equal amount of fuel is more fuel-efficient.

First, convert the given units to have the same unit of measurement,

As 1 gallon =3.7854 liters and 1 mile = 1.609344 km

So, 40 miles =40 x 1.61=64.40 km

Now, The distance covered by Tiyleah's family's car is 64.40 km in 3.7854 liters.

So, the distance covered by Tiyleah's family's car in 1 liter of fuel is $\frac{64.40}{3.7854}=17.01$ km

In a similar way,

As Fantasia's family's car uses 7 liters per 150 km.

So, the distance traveled by Fantasia's family's car in 1 liter of fuel =150/7=21.43 km

Observe that, in 1 liter of fuel, Tyleah's family's car covered 17.01 km while Fantasia's family's car covered 21.43 km which is more.

Hence, Fantasia's family's car is more fuel-efficient.
