Answer:
0.7
Step-by-step explanation:
To find out where to plot the point, you have to multiply -1.4 by -0.5 to get 0.7. Then you find it on the number line and plot it.
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²
So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π
And it's essentially the same process for the other questions.
Given:
The figure of a right angle triangle.
To find:
The value which is equal to r÷q.
Solution:
In the given right triangle, the length of the hypotenuse is q units.
For angle x degrees, perpendicular is p units and base is r units.
For angle y degrees, perpendicular is r units and base is p units.
In a right angle triangle,
So,
Therefore, the value of r÷q is equal to siny or cosx. So, the correct option is C.
A. Because when you try to find something (per) you will divide

Answer:
d. 84.5
Step-by-step explanation:
You will have to put the numbers in order than cross out one from each side;
70x
80x
83
86
88x
88x
In doing this you have taken out B,E, and F. The answer would have to be somewhere in between 83 and 86, which would be around 84 and 85, so therefore the answer would be 84.5
