Answer:

  9:20 am

Step-by-step explanation:

The cycles will coincide again at the least common multiple of the cycle times.

  20 min = 4 × 5 min

  16 min = 4 × 4 min

The least common multiple of these times is 4 × 4 × 5 min = 80 min. 80 minutes after 8 am is 9:20 am.

The two buses will next leave at once at 9:20 am.

Alexis washes 10 1/2 windows in 3/4 hours. At this rate, how many windows can she wash in one hour?
Zepler [3.9K]

Alexis can wash a total of 14 windows in 1 hour

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

Given that Alexis washes 10\frac{1}{2} windows in \frac{3}{4} hours

<u><em>To find: </em></u>number of windows washed in one hour

To simplify the calculations we will convert the given mixed fraction to improper fraction

\begin{array}{l}{=10 \frac{1}{2}} \\\\ {=\frac{2 \times 10+1}{2}} \\\\ {=\frac{21}{2}=10.5}\end{array}

Hence, to wash 10.5 windows, Alexis takes 0.75 hours

Let "n" be the number of windows washed in 1 hour

10.5 windows ⇒ 0.75 hours

"n" windows ⇒ 1 hour

By cross-multiplication we get,

n \times 0.75 = 10.5 \times 1

n = \frac{10.5}{0.75} \\\\n = 14

Thus Alexis can wash 14 windows in one hour

1. Two segments are MC and AX

2. Point N

3. Three collinear points are points A, point N and point X

4. Two other names for V are quadrilateral and rectangle

5. No N, M, and X are in a different plane from R

6. Two rays are ray NR and ray NA

7. The pair of opposite rays with end point N are ray NA and ray NX and ray NM and ray NC

8. Three lines are shown in the figure

Step-by-step explanation:

1) A segment is a line portion with two end points

2) A point marks a position

3) Collinear points are points on the same line

3) A quadrilateral is a four sided figure while rectangle has 90° interior angles

4) A ray is an line extending from a point without ending

5) Opposite rays are rays extending from the same point but in opposite directions

6) A line is a straight one dimensional geometric figure  that has no width but infinite number of points extending without end in both directions
