Deanna has rode her bike 6/7 days this week. What percentage of days has<br> Deanna rode her bike? *

Mademuasel [1]

Answer:

87%

Step-by-step explanation:

We need to convert this fraction to a decimal. To do that, we divide 6 by 7. That gets us 0.85714285714. We need to round that to the nearest hundredth. That gets us 0.86. Now, we need to convert this to a percentage. To do that, we move the decimal two places to the right. That gets us 86. She rode her bike 87% of the days this week.

Triangle FGH has the following side lengths: FG = 5 ft, GH = 10 ft, HF = 12 ft Triangle PQR is similar to triangle FGH. The long

7nadin3 [17]

The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:
$k = \frac{RP}{HF}$
$k = \frac{7.2}{12}$
$k = 0.6$
To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:

For PQ
$PQ = k * FG

PQ = 0.6 * 5

PQ = 3$

For QR
$QR = k * GH

QR = 0.6 * 10

QR = 6$

Answer:
You have that the lengths for the other two sides of triangle PQR are:
$PQ = 3

QR = 6$
