What is the missing leg length
What is the missing leg length - 1

Answers

Answer 1
Answer:

Answer:

36 km

Step-by-step explanation:

This is a right triangle so we can use Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

27^2+ b^2 = 45^2

729+b^2 =2025

Subtract 729 from each side

729-729+b^2 =2025-729

b^2 =1296

Take the square root of each side

b =sqrt(1296)

b=36
Answer 2
Answer:

Answer:

36

Step-by-step explanation:

a2+b2=c2

a2+27^2=45^2

a2+729=2025

a2=1296

then square root that number to get

a=36

How to form mathematical expressions from the given description?

You can represent the unknown amounts by the use of variables.

Follow whatever the description is and convert it one by one mathematically.

For example, if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4.

If something is, for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert descriptions to mathematical expressions.

Step-by-step explanation:

A bag contains 10 pounds of dog food. A family feeds their dogs 0.85 pound of dog food a day. How much dog food is left in the bag after 7 days? Give your answer to the nearest pound.

Answers

A bag contains 10 pounds of dog food.

A family feeds their dogs 0.85 pound of dog food a day so cin seven day the dog eats (0.85 x 7) = 5.95 pounds

so, dog food is left in the bag after 7 days is (10-5.95) = 4.05 pounds
Since there is .85 pounds of dog food fed to the dog everyday it saiz that how many are left in 7 days so our equation is 10-7(.85)=x
10-5.95=x
x=4.05
yet is says round it to the nearest pound so its 4 pounds

Which equations have a negative solution?Choose all answers that are correct.

A. -w/2=11
B. -1/6x=-3
C.-4=v/(-10)
D. -3/4 2=8

Answers

A. w= -22 so A has a negative solution.D doesn't have a variable so I'm not sure about it (did you type it correctly?), but because only one side of the equation has a negative number, I'm guessing D is also a negative solution

The answer is A and D :)))))))))
