Answer:$139.88
Step-by-step explanation:
215,75-75.87 is 139.88
Answer:
0.70p
Step-by-step explanation:
"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%). Next, find the decimal equivalent of 70%:
It is 0.70. Finally, multiply the price p by 0.70: 0.70p (Answer b)
Answer: 67.2°
Step-by-step explanation:
To find angle C, we have to use cosine rule. Therefore,
12² = 8² + 10² - 2 × 8 × 10 × cosC
C = 82.8°
The bearing of A from C will be
= 150° - 82.8°
= 67.2°.
Yes. Use pythagorean theorem to find that: 9^2 + 12^2 =225 and 15^2 =225.
Answer:
y = 3x+3
Step-by-step explanation:
We know the y intercept since it crosses the y axis at (0,3) and we know the x intercept since it crosses the x axis at (-1,0)
We can fidn the slope
m = (y2-y1)/(x2-x1) (0,3) (-1,0)
=(0-3)/(-1-0)
= -3/-1
=3
The equation for the line is in the form
y = mx +b where m is the slope and b is the y intercept
y = 3x+3
