Petra jogs 5 miles in 40 minutes at the rate how long would it take her to jog 11 miles

KatRina [158]

88 minutes (1 hour and 28 mins)

Since 5 miles takes 40 minutes, multiplying both numbers by 2 gets you to 10 miles in 80 minutes. To get the extra 1 more miles you have to find the unit rate

5 miles in 40 minutes : divided both numbers by 5 to get
1 mile in 8 minutes
add the one mile in 8 minutes to the 10 miles in 80 mins and you get 11 miles in 88 minutes

<h3><u>Answer</u> :- </h3>

c) 0.01

<h3><u>Solution</u> :-</h3>

To Write percentage in decimal or fraction we divide it by 100

therefore,

$\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}$

Half of 0.02 = $\sf\frac{1}{\cancel2} \times\cancel{0.02}$

$\implies\boxed {0.01}$

Spencer made a quilt for his cousin's doll. The quilt had a 7x7 array of different color square patches. If each patch is 1 3/4

Damm [24]

Answer:

$\frac{2401}{16}$ square inches

Step-by-step explanation:

Given:

The quilt made by Spencer had a 7×7 array of different color square patches such that each patch is $1\frac{3}{4}$ in long.

To find: the area of the whole quilt

Solution:

Side of each quilt = $7(\frac{3}{4})=7(\frac{7}{4})=\frac{49}{4}$

Quilt is in the form of a square such that area of square is given by $(side)^2$

Therefore, area of quilt = $(side)^2=(\frac{49}{4})^2 =\frac{2401}{16}$ square inches
