How do you figure out 2/5 of a $1.25

Answers

Well 2/5 in decimal form is 0.40. Multiply 0.40 • $1.25. You'll get $0.5

the answer is $0.50 because 2/5 of a dollar is 40% so then you turn that into a decimal which is .4 and multiply that by 1.25.

A room is 5m by 3m and has a height of 3.5m. Find the distance from a comer point on the floor to the opposite comer of the ceiling.

Answers

Answer:

Approximately 6.8m

Step-by-step explanation:

We can picture this problem by drawing a rectangular prism with a width of 5m, a depth of 3m, and a height of 3.5m. To find the length from one corner of the floor to the opposite corner of the floor, we can use the pythagorean theorem and plug in the width and depth of the room for a and b:

$5^(2)+3^(2)=c^(2)$

And now we can solve for c...

$34 = c^(2)$

$√(34)=\sqrt{c^(2)}$

c = 5.831m

Now that we have the length from corner to corner across the floor, we can use the pythagorean theorem again, this time using the length from corner to corner across the floor we just derived and the height of the room:

$5.831^(2) + 3.5^(2)=c^(2)$

And now we can solve for c again...

$46.25=c^(2)\n√(46.25)=√(c^2)$

c = 6.8m

An object moves backwards from where it starts 100 meters in 20 seconds. What is the velocity of the object? Select one:

5 m/s2

-5 m/s

5 m/s

- 5 m/s2

Answers

5m/s

The formula to find the velocity is distance/time.

So 100/20 is 5m/s.
It’s not 5m/s2 because this is the unit for acceleration.
And it’s not negative because it is not possible for the velocity to be negative.

A $300 tablet is on sale for $234. what is the percent of discount ?

Answers

I like to think of these like this.

What was the amount of the discount? 300 - 234 = $66 dollars.

66 is to 300 as ? is to 100?

This is how that question looks in an equation:

66/300 = x/100 Solve for x by cross multipying.

66 x 100 = 300 x

660 = 300 x

x = 22

The discount amount on the tablet is 22% off the regular price.

Check it!

300 x .22 = $66 dollars off. 300 - 234 = $66 off.

Yes! It checks.
