Two lines are perpendicular if their slope m and m' satisfy the equation
The slope of the given line is 4, because the line is written in the slope-intercept y=mx+q, where m is the slope.
So, the perpendicular slope is
So, we want a line with slope -1/4 and passing through (-1,3). We can use the formula
for the line passing trough (a,b) with slope m:
Answer:
the answer is 309
Step-by-step explanation:
Answer: 89.1
Step-by-step explanation: Firstly, for the square, you would multiply 8 by 8 which would result in 64. That is your first addend. Next, to find the area of the semicircle, you find the area of a whole circle, then divide by two. In this case, the area formula would be (pi)r^2. So, the radius would be 4, and in he formula that would end up with the answer being 50.24. Then, you divide by two. 25.1 (rounded to tenths) + 64 = 89.1.
Hope this helped!!
Let's use the ratio 3:6 as an example. So 3:6 is the same as 3 over 6, aka 3/6. Divide 3 by 6 and you'd get 0.50. To turn a decimal into a percent, move the decimal to the left 2 times. (If you want to turn a percent into a decimal, you'd move the decimal to the right 2 times.) So then, 0.50 becomes 50%. Hope I helped!!! :-) (You could also multiply the decimal by 100 if you find that quicker/easier)
Answer:
The correct ratio is 7:8, so no, Emma is not correct.
