Answers

Answer:

√(13)

Step-by-step explanation:

let the 3rd side, the hypotenuse, be x

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )

x = √(13)

Answer:

√13 or 3.6

Step-by-step explanation:

It is a right triangle and you have the measure of the cathets, we use the Pythagorean theorem

√(3² + 2²) =

√(9 + 4) =

√13

Taylor wants to paint his rectangular deck that is 42 ft long and 28 ft wide. A gallon of pain covers 350 sq ft. How many gallons of pain will Taylor need to cover the entire deck? Write and solve an equation to find the area of the deck.

Answers

He will need 3 111/116 gallons of paint. Equation: (42x28)÷350=3 111/116 gallons of paint
Area Equation: 42x28=1176 square feet
42ft*28ft=1176ft²
1176ft²/350ft²=3.36
So, you multiply 42 and 28 in order to find out how large of a space you are needing to paint. You then find out your deck is 1176 square feet. You would then divide by the paint bucket's coverage to find out how many buckets you would need. Then all you have to do is round up so you completely cover it and your answer is 4 buckets of paint, assuming a bucket of paint contains a gallon of paint..

Write an inequality to represent the phrase: The sum of a number and 7 is no more than 53.

Answers


n+7≤53

The sum of a number, which I have named 'n', and 7 can be written as the expression:

n+7

remember the word 'is' in a written problem indicates where you'll most likely use an =,≥,≤ sign. Since they say that it is 'no more than' we know that n+7 is less than or equal to the given number, so we use '≤'.

n+7≤

the number it is less than or equal to is 53, so now we have the completed inequality of:

n+7≤53
sum means add
a number=x
7=7
is no more than, means is equal to or less than aka <
53=53

x+7<53
