The fraction is 12/1000 which simplified to 3/250. The percentage is 1.2%.
Bond [772]3 years ago
4 0

Fraction is 12/1000 and the percent is 0.00012

The top person is wrong because he/she moved the decimal to the left but when you find percent, it's suppose to be moved to the right twice.

Answer=60

Since the base of the prism is a right triangle, we can use the pythagorean theorem to solve for x.

a²+b²=c²
plug in the data
a²+24²=30²
a²+576=900
subtract 576 from both sides
a²=324
sq root
a=18
So x=18


The formula for the volume of a triangular prism is...

V=(area of the base)*(height)
V=1/2bh*H      where b=base of triangle h=height of triangle, H=height of prism
plug in the data that we know
720=1/2*18*24*H
720=216*H
divide both sides by 216
3 1/3=H

So x=18 and y=3 1/3 or 3.33 repeating

The product of the two

18*3 1/3=60

Answer=60

Question 6 of 6
Bezzdna [24]

\huge \boxed { \sf \: Answer}

We have to use the formula:

(ab) ^{n}  =  {a}^{n}  {b}^{n}

So,

(5 \times 9) ^{12}  \\  =  {5}^{12} . 9^{12}

Also, it will be

45^{12}

Hope you could understand.

Element X decays radioactively with a half life of 9 minutes. If there are 890 grams of Element X, how long, to the nearest tent
elena-s [515]

Answer:

13.18651685

13.9

Explain:

890-238=652
652/890=0.7325842697 (Find out the percentage)

We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.

0.7325842697x18=13.18651685

As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)

And of course we need to round it to nearest tenth. So the answer would be 13.9!
