Answer:
2√(5)
Step-by-step explanation:
Since it's stated that thegiven is right triangle :
The square length of hypotenus (the side lenght that sees 90 degrees) is equal to sum of square length of side lengths
2^2 + 4^2 = x^2
4 + 16 = x^2
20 = x^2 and x = 2√(5)
Answer:
1410
Step by step explanation:
<em>2</em><em>/</em><em>5</em><em>x</em><em>=</em><em>5</em><em>6</em><em>4</em>
<em>5</em><em>/</em><em>2</em><em>*</em><em>2</em><em>/</em><em>5</em><em>x</em><em>=</em><em>5</em><em>6</em><em>4</em><em>*</em><em>5</em><em>/</em><em>2</em>
<em>x</em><em>=</em><em>1</em><em>4</em><em>1</em><em>0</em>
<em>Proof</em><em>:</em><em> </em><em>2</em><em>/</em><em>5</em><em>*</em><em>1</em><em>4</em><em>1</em><em>0</em><em>=</em><em>5</em><em>6</em><em>4</em>

Answer:
A
Step-by-step explanation:
Substitue 15 into the x value and complete the equation.
This is because 2,280 is the original distance. 15 would be the hours and 60 would be how many miles per hour. So we multiply 15 and 60 and get 900, this is how many total miles they have driven. But when we subtract that number from 2,280, and we get 1,380, this is how many miles they have left.
Answer:
9.3
Step-by-step explanation:
Step 1: Calculate. We calculate the square root of 87 to be: √87 = 9.32737905308882.
Step 2: Reduce. 9.32.
Step 3: Round. Round 9.32 so you only have one digit after the decimal point to get the answer: 9.3.
750 kilometers. 21 divided by 7 is 3. If 7 cm equals 250 km, then 7 × 3 = 250.
