Answer:
Elena's run for 1.17 miles in ten minutes
Step-by-step explanation:
From the question
y = 8.5 x ; where x is Distance in miles, and y is time in minutes
and y= 10 minutes
thus on substituting the respected values we get
10 = 8.5 x
⇒ x = 
= 1.17 miles
Therefore Elena's run for 1.17 miles in ten minutes

Answer: 9</h3>
================================================
Work Shown:
a = unknown = leg #1
b = 12 = leg #2
c = 15 = hypotenuse
Plug those values into the pythagorean theorem and solve for 'a'
a^2 + b^2 = c^2
a^2 + (12)^2 = (15)^2 .... substitution
a^2 + 144 = 225
a^2 = 225 - 144 ... subtracting 144 from both sides
a^2 = 81
a = sqrt(81) .... applying square root to both sides
a = 9
Answer:
Step-by-step explanation:
(A). $20.00 × 160 = $3,200.00
(B). $1,590.67
(C). $3,200.00 - $1,590.67 = $1,609.33
Answer:
x = 36.9°
Step-by-step explanation:
We need to find out what sides of the triangle we have, <em>so we can find the formula for the missing angle, x.</em>
We have been given the <em>opposite</em> and <em>hypotenuse</em> so we are using sine
SOH, CAH, TOA
sin (x) = opp ÷ hyp
<em>Substitute in the values</em>
sin (x) = 9 ÷ 15
<em>Simplify</em>
sin (x) = 0.6
<em>Rearrange to find x</em>
x = sin^-1(0.6) - Type this into your calculator
<h3>
sin^-1 is the inverse or opposite of sin</h3>
x = 36.8698... ≈ 36.9°
