Answer:
missing value is 5
Step-by-step explanation:
Change them to all have the same denominator
8/12 + 3x/12 = 23/12
multiply all by 12
8 + 3x = 23
subtract 8
3x = 15
divide by 3
x = 5
First things first when multiplying and dividing positive and negative numbers if the two signs are the same it's positive, and if both signs are different it's negative.
you simply just multiply and divide the same as you would normally you just have to pay attention now if the answer is positive or negative.
Well I personally do not know the volume of a cylinder but for example if you had a cylinder that the radius(had of the diameter) was 5 and say the height was 13 then you could go on google, safari, etc. and search exactly this (also works with triangles, rectangles, squares, circles, parallelograms, trapezoids, etc. and also with the volume and surface area of triangular prisms, rectangular prisms, etc.) but any way type in this: what is the formula for the volume(area, Surface Area, etc.) of a cylinder(rectangular prism, triangular prism) you put in the height and the radius of the cylinder and the answer will automatically pop up if this didn't help(which I really hope it did!!) the I am terribly sorry
37 percent take away the zero
There are
female teachers, and
male teachers.
This means that, out of a total of 75 teachers, 45 are female, leading to a probability of
of selecting a female teacher.
If we restrict to those with more than 8 years service, there are 13 female teachers and 7 male teachers.
So, out of a total of 21 teachers, there are 13 female teachers, leading to a probability of
of selecting a female teacher.
