Answer: The pythagorean theorem states that a² + b² = c². 
We have a = 10 and c = 20. 
100 + b² = 400 
Subtract 100 from each side. 
b² = 300 
Get the square root of 300. 
It could be expressed as b ≈ 17.321, or could stay in radical form as√(300)
Hope this helps!

In a machine, a large gear completes a revolution every minute while a small gear completes a revolution every 24 seconds. If the gears are currently aligned, how much time will pass before they are aligned again?

Answers

This question is asking you for the least common multiple of 60 (seconds in 1 minute) and 24 (seconds in 24 seconds).
I think it's 120 (you should check it) and that would be 3 minutes.

Multistep Alex needs to varnish the top and the bottom of a dozen rectangular wooden planks. The planks are 8 feet long and 3 feet wide. Each pint of varnish covers about 125 square feet and costs $3.50. a. What is the total area that Alex needs to varnish? b. How much will it cost Alex to varnish all the wooden planks?

Answers

top and bottom
find area of each plank top and m ultiply by 2 then by number of planks
8*3*2*12 (dozen=12)
576

he needs to varnish 576 ft^2
how many 125's are at least 576 (round up since he can't buy fractios of a pint probably)

125x>576
dividee both sides by 125
x>4.608
x=5

5 times 3.5=17.5





a. 576 ft^2
b. $17.5

What is the quotient of 5.4 and -0.3

Answers

Hey there!

The "quotient" is basically the result of a division equation

Remember: \n -,- = + \n +,+ = + \n-,+ = - \n +,- = -

This pair is: +, - (Positive (+), negative (-)

So, this means your result will be a negative

(5.4)/(-0.3) = -18 \n \n (-0.3)(-18) = 54 \n -18 = -18

Therefore your quotient is -18

Good luck on your assignment and enjoy your day!

Hello!

If you divide or multiply by one negative number, the number will remain negative. Let's just divide 5.4 and 0.3, and add a negative after.

5.4/0.3=18

We add our negative

-18

Therefore, our quotient is -18.

Teds last 3 test scores were 82 91 88 what is the average of his test scores

Answers

The average of his test scores is 87%.
To find the average of a group of numbers, you have to add all the numbers up, and divide the total by how many numbers you added together.
Teds average is 87%. To find the average you must add up all the numbers, and then divide them by the number of numbers there are lol. Hope this helps! <3
