Nutka1998 [239]

Answer: 2 1/4 hours

Step-by-step explanation:

If Rafael practices 3/4 of an hour each day for three days he will have had 3/4 of an hour practice after day 1, 1 1/2 hours of practice after day 2 and then 2 1/4 hours of practice after day 3.

3 x 3/4 = 9/4

9/4= 2 1/4

Please answer I’ll make brainliest. I have other questions too that I’ll be posting shortly

ziro4ka [17]

Answer:

16 ft

Step-by-step explanation:

The equation is a^2+b^2=C^2

a= 30^2 = 900

b= we need to find

c= 34^2=1156

so the equation looks like this so far

900 + B^2 = 1156

we are going to subtract 900 so B^2 can be alone

1156 - 900 = 256

Now the equation looks like =

B^2 = 256

now we square root 256

which gives you 16

B = 16

Johns car averages 28 miles per gallon. how far can her drive on 8.25 gallons

Lilit [14]

Answer:

Step-by-step explanation:

This is a unit problem.

$\frac{28mpg}{8.25g}$

If you notice in that ratio, there is a "g" in both the numerator and the denominator which will cancel out, leaving you only with the label of miles, which is what you are looking for (since "how far can she drive..." is a distance thing). 28 then only needs to be divided by 8.25 to see how many miles this is.

$\frac{28mpg}{8.25g}=3.3939393939$ miles which, in an improper fraction, is

$\frac{112}{33}$ miles

Square ABCD has a side length of 4 inches. The square is dilated by a scale factor of 4 to form square A'B'C'D'. What is the sid

Amiraneli [1.4K]

We have been given that square ABCD has a side length of 4 inches. The square is dilated by a scale factor of 4 to form square A'B'C'D'. We are asked to find the side length of square A'B'C'D'.

We know that when scale factor is greater than 1, then the resulting figure would be an enlargement.

To find the side length of new square after dilation, we will multiply the original side by scale factor.

$\text{New side length}=\text{Original side}\times \text{Scale factor}$

$\text{New side length}=\text{4 inches}\times 4$

$\text{New side length}=16\text{ inches}$

Therefore, the side length of square A'B'C'D' would be 16 inches.
