Answer:

0.75 or 3/4 = r

Step-by-step explanation:

To figure out the value of r, you must find the square root of both sides, which would cancel the square. Now the equation would be 4r = 3. From there, you can divide both sides by 4 to get r by itself. so now, the equation is r=3/4 or 0.75

The sum of three consecutive numbers is 72. What are the smallest of these numbers?

spayn [35]

Answer: 23,24,25

Step-by-step explanation:

Obviously the numbers are about 72÷3 = 24 so see if 23,24,25 works. It does. No need to solve

(i-1) + (i) + (i+i) = 72, 3i=72, i=24.

Factor 15 + 50. 5(10 + 3) 5(3 + 10) 3(5 + 25) 10(5 + 5)

Agata [3.3K]

Answer:

Step-by-step explanation:

So we have the expression:

$15+50$

Since 5 goes into both 15 and 50, we can factor out a 5. First, rewrite the numbers as:

$5(3)+5(10)$

Factor out the 5:

$=5(3+10)$

So, our answer is B

And we're done!

The table shows the distance in feet, y, that a rocket traveled in x seconds.

Murrr4er [49]

Answer:

The correct option is D. y = 25 $x^{2}$ .

Step-by-step explanation:

i) From the table and our own observation and a trial and error approach we

can clearly see that the equation that matches y in feet ( the distance

traveled by the rocket) and x in seconds ( the time elapsed) is given by the

equation y = 25 $x^{2}$

Therefore the correct option is D. y = 25 $x^{2}$ .

Can someone please check if this is correct?

Solnce55 [7]

Answer:

Just two corrections! See attached image.

Step-by-step explanation:

The product of 8 and b taken from 10 means begin with 10 and subtract 8b from it.

8 times the difference of 10 and b means find 10 - b first, then multiply by 8.
