Answer:
y = 240.3 ft to the nearest tenth.
Step-by-step explanation:
The bottom left angle = 31 degrees ( interior alternate angles).
tan 31 = y / 400
y = 400 tan 31
y = 240.34 ft.
Answer:
Steve is 5
Step-by-step explanation:
Steves sister is 25, she is 5 years more than 4 times steve is.
5 * 4 = 20 and the sister is 5 years older so,
Steve is 5
Answer:
um i can't really understand what your trying to do here
Step-by-step explanation:
Answer:
y = 2x - 18
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (4, -10) and Gradient (m): 2
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - (-10) = 2(x-4)
This becomes:
y + 10 = 2x - 8
Keep solving by moving the 10 over to the other side:
y = 2x -8-10
y = 2x - 18
<u>An easy way to double check:</u>
1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.
2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.
Hope this helped : )
well 4/6 is two-thirds so you would do 86/3 which is 28.66666..... (that is one-third)
Then you multiply that by 2 to get two-thirds which would therefore be equal to 4/6 (28.66666 x 2 = 57.3333...)
57.33333 rounded is 57.3
