Hello,
let's assume a the width, b the heigth.
sin 30°=a/26=1/2==>a=26/2=13 (in)
cos 30°=b/26=√3/2==>b=26*√3 / 2=13√3≈22.51666.... (in)
Answer:
Step-by-step explanation:
Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub...we r looking for b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
equation is : y = 3/4x + 19/4...lets put this in standard form
y = 3/4x + 19/4
-3/4x + y = 19/4...multiply by -4
3x - 4y = -19 <== standard form
if (x,5) is on the line
3x - 4y = -19.....sub in 5 for y
3x - 4(5) = -19
3x - 20 = -19
3x = -19 + 20
3x = 1
x = 1/3 <====so point a = (1/3,5)
Answer:
A
Step-by-step explanation:
You're right:) distribute the 3 and have the y alone and it's A
Answer:
-4a
Step-by-step explanation:
5a + -9a = -4a

Answer:
It will take him 2 and a half weeks to get 80 miles. Approximatly 19 or 18 days.
Step-by-step explanation:
He runs to times a week.
2/7 = 16
80/16
5.
So he'll have to run 5 times.
2 times a week. 2 weeks equals 4 runs. Then 2 and a half weeks equals 5.
