Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.
Subtituting the value in the formula.
⇒ 
⇒ 
Putting square root on both side
We know, √a²= a
⇒ 
∴ hypotenous= 11.18 
Hence, the slope is 11.2 feet

C is answer
Answer:
14 weeks till he has $480
Step-by-step explanation:
He needs $480
He has $60
He has to earn the rest over the span of the next few weeks, which is $30 for an unknown number of weeks.
Let the unknown number be x in our equation
What he needs to buy the TV and Stereo system is $480 which is our total
The $60 dollars he received is a complete variable
hence we can say,<em> 30x+60=480</em>
<u>This is our equation</u> but it isn't simplified.
first, divide everything by 10(it is a common divisor)
<em>3x+6=48</em>
<em>subtract</em> 6 which is complete from the total
3x=42
Make x the subject and divide both sides by 3
x=14
so the unknown number of weeks is 14.
