Answer:

Additive Inverse

Step-by-step explanation:

What you add to a number to get zero.

The negative of a number.

Example:

The additive inverse of −5 is +5, because −5 + 5 = 0

The additive inverse of +5 is −5, because +5 − 5 = 0

Answer: The value of the stove after 5 years is $1121.54

Step-by-step explanation:

Given: The price of stove A= $1150

The price depreciates about 0.5% each year.

In decimal the rate of depreciation r= 0.005

The value of the stove after x years is given by

$P=A(1-r)^x$

The value of the stove after 5 years is given by

$P=1150(1-0.005)^5\\=1150(0.995)^5\\=1150(0.975248)\\=1121.5360$

Hence, The value of the stove after 5 years is $1121.54.

Your ship has steamed 1651 miles at 20 knots using 580 tons of fuel oil. The distance remaining to your next port is 1790 miles.

oee [108]

The 680 tons of fuel needed to cover the next 1790 miles distance.

According to the statement

We have given that the ship covered a 1651 miles distance at 20 knots by a 580 tons of fuel oil.

And distance remaining to next port is 1790 miles and speed increases to 25 knots.

And we have to find that how much fuel used to reach that port.

So, Distance covered = 1651 mile

fuel used = 580 tons

distance covered with 1 tons fuel = 1651/580

distance covered with 1 tons fuel = 2.85 mile at a speed of 20 knots.

so, The fuel consumption for 1790 mile is = 1790/2.85

The fuel consumption for 1790 mile is = 628 tons of fuel needed.

So, The 680 tons of fuel needed to cover the next 1790 miles distance.

The distance on a city grid is measured in blocks. On the grid, the coordinates for the location of your house are (2,6). The In

dolphi86 [110]

The answer is C) 16 blocks.

We will use the distance formula for this problem:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

From your house to the internet cafe:

$d=\sqrt{(8-6)^2+(12-2)^2}=\sqrt{2^2+10^2}=\sqrt{4+100}
\\
\\=\sqrt{104}=10.2$

From the internet cafe to your friend's house:
$d=\sqrt{(8-4)^2+(12-8)^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}=5.7$

Together, we have 10.2+5.7=15.9, which rounds to 16 blocks.
