Answer:
101 meters
Step-by-step explanation:
The direct path across the stream and perpendicular to both sides of the stream is one leg of a right triangle. The 20 meter distance on the arriving side of the stream is another leg of the right triangle. The path he actually took is the hypotenuse of the right triangle.
leg 1 = 99 m
leg 2 = 20 m
hypotenuse = ?
We have a right triangle, and we know the lengths of the two legs. We need to find the length of the hypotenuse, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2
99^2 + 20^2 = c^2
9801 + 400 = c^2
c^2 = 10201
c = sqrt(10201) = 101
Answer: 101 meters
Answer:
<h2>____</h2><h3>1260 </h3><h2>____</h2>
Since we have to predict, we can use ratios to help us solve this.
12 said yes out of 72 randomly chosen, SO,
if 210 would say yes (goes to play), how many is total??
12 is to 72 AS 210 is to HOW MUCH (let it be x)??
We can setup ratio, cross multiply, and solve for x:
= 12/72= 210/x
= 12x = 210*72
=12x = 15,120
=x = 15,120/12
<h2>=x =1260</h2>

Answer:
B
Step-by-step explanation:
Because 15-4=11
and both angles are equal
Step-by-step explanation:
y = 2/5 x - 9/5
when x = -1,
the value of y = 2/5(-1) - 9/5
= -2/5 - 9/5 = -11/5
when x = 0
=> y = 2/5(0) -9/5
= 0-9/5 = -9/5
when x=1
=> y = 2/5(1) - 9/5
= 2/5 - 9/5 = 7/5
