Answer:

63

Step-by-step explanation: The ratio from planet A to B is 100 to 3. If an elephant weight 2100 is planet a, then we are multiplying 21 to hundred. Whatever you do on the left side you have to do it on the right side and if you multiply 21 and 3 on the right side then you get 63.

Answer:

63 pounds

Step-by-step explanation:

<em>The ratio for Planet A to Planet B is </em>

100 : 3

<u><em>Creating a proportionality with the unknown as x</em></u>

=> \frac{100}{3} = \frac{2100}{x}

Isolating x would give

x = \frac{2100 * 3}{100}

x = 21 × 3

x = 63 pounds

For A the great common factor is 3 because if you were to do 3,6,9 and then 36- 3,6,9,12,15,18,21,24,27,30,36 the greatest common factor (GCF) would be 3.

For B the greatest common factor is 28 because if you were to do 7,14,21,28, twenty-eight is the highest number possible and for 42 you would do 7,14,21,28,35,42 the highest number possible for them to match would be 28 so the answer is 28 for B

I WILL GIVE A BRAIN LIST TO THE FIRST PERSON WHO ANSWERS!!!!!!!
aksik [14]

Answer:

its c

Step-by-step explanation:

Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.

If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

<u>33 x 1 </u>

40 x 1

 

<u>3 x 10 </u>

4 x 10

This is what 33/40 and 3/4 looks like with the same denominator:

<u>33 </u>

40

&  

<u>30 </u>

40

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 33 is greater than 30 which also means that 33/40 is greater than 3/4.

What is the midpoint of the line segment with endpoints (-2,-2) and (4.6)?
erma4kov [3.2K]

Answer:

Step-by-step explanation:

(-2,2) ...x1 = -2 and y1 = 2

(4,6)..x2 = 4 and y2 = 6

midpoint formula :

m = ((x1 + x2) / 2 , (y1 + y2) / 2)

m = ((-2 + 4) / 2 , (2 + 6) / 2)

m = 2/2 , 8/2

m = (1,4) <===
