SOCCER PRACTICE BEGAN AT 2:30 P.M 3:30 P.M THROUGH WHAT FRACTION OF A CIRCLE DID THE MINUTE HAND TURN HOW MANY DEGREES DID THE M

MrMuchimi

Answer:

1 /1 ; 360°

Step-by-step explanation:

Start time = 2:30 pm

Stop time = 3:30 pm

Minute hand makes a complete revolution per hour ;

This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1

The angle turned by the minutes hand :

1 complete revolution = 360°

A circle covers 360°

1 /1 fraction of a circle = 1/1 * 360° = 360°

Hence, angle turned by the minute hand = 360°

Jason started with d dollars in his piggy bank. One week late, Jason doubled the amount in his piggy bank. Another week later, j

elena55 [62]

Given, Jason had an amount of $d in the piggy bank.

After one week, Jason doubled the amount in the piggy bank.

So, after one week the amount in the piggy bank = $ $(2)(d)$ = $(2d)

Another week later, Jason added $20 in the piggy bank.

So after another week, the total amount in the piggy bank = $ $(2d+20)$

Given, that time the piggy bank had $50 in it.

So we can write the equation as,

$2d+20 = 50$

To find the value of d, we will move 20 to the right side by subtracting it from both sides. We will get,

$2d+20-20 = 50 - 20$

$2d = 50 -20$

$2d = 30$

Now to find d, we will move 2 to the right side by dividing it to both sides. We will get,

$\frac{2d}{2}=\frac{30}{2}$

$d = 15$

We have got the required answer.

The value of d = $15.

5. A pole has to be erected at a point on the boundary of a circular park of diameter 13 metres in

lesya [120]

Answer:

Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.

Step-by-step explanation:

Let P be the required location of pole .

A and B are the two gates.

Let the distance of pole at p from gate be 'x' meters

i.e. PB = x m

•°• AP = (x + 7)m and AB = 13 m

•°• AP² + BP² = AB² => (x +7)² + x =13²

Rejecting x =-12, we get x = 5

•°• PB = 5m

and

AP = 12m

(I hope this helped :)
