Answer:
32
Step-by-step explanation:
Change 50% in to a decimal. To do that you move the decimal point two spaces to the left giving you .5. So .5x64=32
Answer:
I think 12.7
Step-by-step explanation:
There are 2 shorter sides of a rectangle so thats 8 centimeters. 33.4-8=25.7 25.7/2=12.7
Sorry if wrong!
Answer:
107.500
Step-by-step explanation:
5.450.000-75.000=5.375.000
5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000
430.000:4=107.500
+ and - ,
* and :
are inverse operations
Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.
verifying :
107.500*4*12 1/2+75.000=5.450.000
Step 1
<u>Find the slope of the line PQ</u>
we know that
the formula to calculate the slope between two points is equal to
we have
substitute the values
Step 2
Find the equation of the line that passes through point R ans is parallel to line PQ
we know that
If two lines are parallel, then their slopes are the same
The equation of the line into point-slope form is equal to
we have
substitute the values
Step 3
we know that
The point on the y-axis that is on the line is equal to the y-intercept of the line
The y-intercept is the value of y when the value of x is equal to zero
so
For find the value of y in the linear equation
The point that is on the y-axis is
therefore
<u>the answer is the option A</u>
see the attached figure to better understand the problem
The formula for the volume of a cone is V=1/3(pie)r²h. So if you know the radius and the voume, plug those numbers in for V and r respectively and solve for h
