Answer:

8 minutes if Jane was assumed to be stationary

Step-by-step explanation:

The question is on relative speed

First find the distance covered by Jane when Sally left school

Speed=Distance/Time ⇒⇒ Distance=Time×Speed

Time=10minute=10/60 hrs

Jane's speed= 12mph

Distance covered by Jane when Sally left school was= 12 ×10/60 = 2miles

So, when Sally left school, Jane was 2 miles away. To find the time Sally requires to catch up with Jane;

Time=Distance/speed

Time of meeting =2/15 hrs ⇒⇒ 2/15 × 60 =8minutes

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

<em>You could really just do 7 * 3 here.</em>

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.

<u>Step-by-step explanation:</u>

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find  , Which golfer had the lowest number of strokes per hole :

<u>Rory:</u>

Number of strokes per hole = \frac{424242}{999}  = 425

<u>Alicia:</u>

Number of strokes per hole = \frac{797979}{181818}  = 4

<u>Rickie:</u>

Number of strokes per hole = \frac{123123123}{272727}  = 451

∴ Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.

#10-1 : What is the probability of randomly choosing a diamond card from a regular deck of 52 cards? What is the probability of
Alchen [17]

\huge{\boxed{\frac{1}{4}}}\ \ \huge{\boxed{\frac{1}{4}}}

There are 13 of each suit in a deck of 52 cards.

This means the probability of drawing a diamond card is \frac{13}{52}. You can divide the numerator and denominator each by 13 to simplify. \frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}

Since there are the same number of clubs as there are diamonds, the probabilities are the same.
