Answer:
180 miles
Step-by-step explanation:
Going North
<em><u>Formula</u></em>
d = r * t
<em><u>Givens</u></em>
r = 60 mph
t = 5.2 hours
d = ?
<em><u>Solution</u></em>
d = 5.2 * 60 = 312 miles north
Going South
<em><u>Givens</u></em>
r = 55 mph
t = 2.4 hours
<em><u>Solution</u></em>
d = r * t
d = 55 * 2.4
d = 132
Distance from home
Formula: Distance from home = Distance North - Distance South
Distance North = 312 - 132 = 180 miles
Answer:
x-3 and y=2
Step-by-step explanation:
Answer:
<h3>The length of y is 62.82 cm.</h3>
Step-by-step explanation:
We are given a right triangle with an angle 30°.
Opposite side of angle 30° is x and adjacent side is y.
Also, given length of side x=36.25 cm.
In order to find the value of y, we need to apply tangent trigonometrical ratio.
We know,

Therefore,

Plugging values of
and x=36.25, we get

Plugging value of
in above equation, we get

On multiplying both sides by y, we get

0.577y=36.25
Dividing both sides by 0.577, we get

y=62.82
<h3>Therefore, the length of y is 62.82 cm.</h3>
To find the mean, add up all the test scores and divide by the number of tests:
524/10 = 52.4.
