Answer:
the correct answer is a
Step-by-step explanation:
25/2=12.5 and 12.5>12 which is given. All the other possible answers are false because the numbers being multiplied are smaller than 19 or 12.
Answer:
a=169 ft
Step-by-step explanation:
Here you are given the angle 25, and the opposite and hypotenuse values.
Opposite/Hypotenuse: the sin(angle 25)=a/400ft.
We need to solve for a, so lets multiply 400 to the other side:
400(sin25)=a. Plug this into your calculator and you will get the answer: a=169.04 ft
Answer:
165 ft^2
Step-by-step explanation:
We need to break the figure into 2 parts
We have the square at the bottom right
The square is 5 by 5
A = 5*5 = 25
The rectangle is then 20 by (12-5) =7
The area of the rectangle is
A = 20 *7 = 140
Add the areas together
140+ 25
165 ft^2
So let us set up the equations:
d = rt
d = 12t and plug in r = 12
so after t hours, the faster runner is 12t miles which is
for the faster runner.
d = rt
d = 8t plug in r = 8
so after t hours, the slower runner has 8t miles.
Now if you want to get the distance, simply subtract:
12t – 8t = 4t
Since we need to get the distance of ¼ mile, meaning:
12t – 8t = ¼
= 4(12t – 8t) = 4 x 1/4 -> multiply both sides by the lcd
to clear the fractions
= 48t – 32t = 1
=16t = 1
Get t by dividing both sides by 16 to isolate t.
So the answer is 1/16 which is about 0.0625.
