Answer:
Step-by-step explanation:
You subtract 310 from 25 and get 285 then you multiply 285 x 21 and I believe that should solve this equation.
It's B
Slope is negative, the other must be positive due to m1 x m2 = - 1
m1 = -2/5
The diagram shows a gradient of -2/5. So, the
reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)
-2/5 x 5/2 = - 10/10 (or - 1)
Thus, the perpendicular line to this has a gradient of 5/2.
Hope this helps!
Answer:
1017.9
Step-by-step explanation:
Find the area of the circle on top first using 3.14*r^2
3.14*9^2 = 254.5
Multiply this number by the height, 4
254.34*4 = 1017.9
Answer:
I think the answer is neither
Answer:
Jayln rode 12.4 miles/hour.
Step-by-step explanation:
The question is asking for a unit rate for the speed in miles per hour that Jayln rode her bike over her 33.48 mile ride. Since we know that she rode a total of 33.48 miles and the total time was 2.7 hours, we can set up our ratio as 33.48/2.7 or miles/hours. In order to find unit rate, or the number of miles per one hour, we need to divide: 33.48 ÷ 2.7 = 12.4. So, 12.4 mph is Jaylyn's speed.
