The hypotenuse of a right triangle is 50 mm. One leg of the right triangle is 30 mm. What is the length of the other leg? (4 points)
Group of answer choices

20 mm

40 mm

30 mm

60 mm

Answers

Answer:

40 mm

Step-by-step explanation:

It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.

This means the unknown number plus 30^2 = 50^2

What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.

You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.

40 mm is your final answer.

Answers

Sales tax =0.06 so if you’re adding that to 46 then you have to do 46x1.06 which gives you the answer to how much Nate spends in total. Then you should be able to answer the question.
You multiply .06 times 46 then add it to 46 and see what the total is. If it’s more than 50 he won’t have enough

Hello davetriona12! I believe I can help you.

So, we are trying to find the missing numbers. We have 6.54, 6.79, 7.29, and 7.79

In order to find the answer, we must learn how much is being added to each number. We can do this by subtracting: 6.54 by 6.79 which would give you 0.25

So now we know that each number goes up by 0.25

Now, we need to find the missing numbers by adding 0.25

6.79 + 0.25 = 7.04

7.29 + 0.25 = 7.54

So, the first blank is 7.04

The second blank is 7.54

I hope this helped you.

Answer:

B

Step-by-step explanation:

12.7x+69.6 ≤ 603

Subtract 69.6 from both sides of the equation

12.7x ≤ 533.4

Now divide both sides by 12.7. Since this is not a negative number, do not flip the sign.

x ≤ 42

Now graph the equation. Now since this is a less than or equal to sign, there will be a closed circle. put a dot where there is a 42, then put an arrow going to the left to represent that x is less than or equal to 42.

You can see this description in option B.
