rosa correctly solved 275 divided by 5.enter numbers in boxes to show the equations she could use to solve the problem

kifflom [539]

Answer:

The first step would be to look at the first two numbers (which is 27) and estimate which <u>multiple</u> of 5 is closest and <u>below</u> 27.

5*5 = 25

So once she got 25, she will need to subtract 27-25, which will give her 2. REMEMBER: 5 is the first number of the quotient.

Now, she will need to drag the last digit left of 275 (which is 5) to the remainder 2 and think what multiple of 5 will give her the answer 25.

Again, 5*5 = 25

Once again, her numbers on the quotient will be 55. That's the answer.

The time a basketball player spends in the air when shooting a basket is called the "hang time." the vertical leap l measured i

Marina86 [1]

Dénote l the vertical leap, then the given equation can be written like this:
$l(t)=4t^2\\\text{Since one inch equate 0.0833333 feet then 44 inches equate }\\44\times 0.0833333=3.6feet\\\text{Add to 33 feet like this:}\\33+3.6=36.6feet\\\text{Now we have to solve the equation:}\\4t^2=36.6\\\text{Divide over 4 we get:}\\t^2= \frac{36.6}{4}=9.15\\\text{Take the square root we get:}\\t=\sqrt{9.15}=3$

The hang time equates then 3 seconds
