Answers

Answer:

75 degrees

Step-by-step explanation:

At 3:30, the hour hand is halfway between the 3 and the 4. The minute hand is exactly on the 6.

There are 360/12 = 30 degrees between each of the marked hours. The angle between the hands covers 2.5 of these gaps, so the angle between the hands is 2.5(30) = 75 degrees.

Hope this helps!

The angle between the hands at 3:30 pm is 90°.

What is the angle between the hands of a clock at 3:30 pm?

At that time, one hand points at the 3, and the other hand points at the 6.

Now, there is a rule to transform time into angles.

We know that a clock has 12 hours in a full revolution, and a circle has 360° in a complete revolution.

Then we know that:

12 hours = 360°

Then:

1 hour = (360°/12)  = 30°

So each between each number in the clock we have an angle of 30°.

Then, between 3 and 6 (3 hours) we have:

3*30° = 90°

The angle between the hands at 3:30 pm is 90°.

Hayden and Jamie completed 20 math problems together. Jamie completed 2 more than twice the number that Hayden completed. Let p represent the number of math problems Hayden completed. Write an equation that can be used to find the number of math problems that Jamie completed.​

Answers

Answer:

3p + 2 = 20

Step-by-step explanation:

p = number of math problems Hayden completed

Jamie completed 2 more than = +2

twice the number that Hayden completed = x2

So 2p+2 = number of problems Jamie completed

Since they completed a total of 20 questions, the equation would need another +

(Hayden's problems) + (Jamie's problems) = 20

(p) + (2p+2) = 20

This can be simplified to 3p + 2 = 20, and you can then solve for p

Answer:Equation to solve the question

=Distance = Speed x time

=d= 0.6 x 30

Distance , d= 18 miles

Step-by-step explanation:

Step 1

Speed = distance / time

Therefore  Distance = Speed x time

Given that speed = 0.6 miles per minute  and

Time=30 minutes

Step 2

Distance ,d= 0.6 miles per minute x 30minutes

d= 0.6 x 30

= 18miles
