This is my thinking;

To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057

You need to convert m to km. There are 1000m per km, so divide your m by 1000. 56m=0.056km

Find the quotient of 48a^4-16a^2-32/8a^2-8
Novay_Z [31]
We know that if we had
8/6=2/2 times 4/3=1 times 4/3=4/3
find common factors in top and obttom
factor
48a^4-16a^2-32=(16)(a-1)(a+1)(3a^2+2)
8a^2-8=8(a-1)(a+1)
so we have
\frac{48a^4-16a^2-32}{8a^2-8} = \frac{(2)(8)(a-1)(a+1)(3a^2+2)}{(8)(a-1)(a+1)}= (\frac{8}{8}) (\frac{a-1}{a-1})( \frac{a+1}{a+1}) ( \frac{(2)(3a^{2}+2)}{1})=(2)(3a^2+2)=6a^2+4


answer is 6a^2+4

ABCD∼EFGH AD=45 in. , EH=75 in. , and AB=30 in. What is EF ?
Marrrta [24]
EF = 50 in.

In similar figures, corresponding sides are proportional.  We use the similarity statement ABCD~EFGH to write a proportion:

\frac{AB}{EF}=\frac{AD}{EH}
\\
\\ \frac{30}{x}=\frac{45}{75}

Cross multiply the proportion:
45*x = 75*30
45x = 2250

Divide both sides by 45:
45x/45 = 2250/45
x = 50

There is a Minecraft sale for 30% off all games. Which expression represents the total cost of Minecraft Dungeons if it cost x d
diamong [38]

Answer:

The expression x-0.3x represents the total cost of Minecraft Dungeons.

Step-by-step explanation:

Given that:

Percentage of Minecraft sale = 30% off

Cost of Minecraft Dungeons = x

Amount of discount on Minecraft Dungeons = 30% of x

Amount of discount = \frac{30}{100}*x

Amount of discount = 0.3x

Total cost of Minecraft Dungeons = Total cost - Discount

Total cost of Minecraft Dungeons = x - 0.3x

Hence,

The expression x-0.3x represents the total cost of Minecraft Dungeons.

Can anybody help? Having a little trouble with this during quarantine...
kolbaska11 [484]
First you would have to find the base which would be 9^2 + 9^2= C^2 because of the pythagorean theorem. So the base would equal 12.7. To find the area of a triangle it’s A= h•b / 2. So your answer would be 95.25
