A secretary can type 79 words per minute he works 5 eight hour days each week how many words does he type in a week?​

189,600 words in a week

Step-by-step explanation:

This can be a imposing question, but if you use the proper steps and planning, it can become easy. First, we need to muliply 79 by 60 to find out how many words he types in an hour.

79*60=4740

Now we multiply 4740 by 8 to find how many words he types in a day.

4740*8=37920

Lastly, we can multiply 37920 by 5 to find out how many words he types in a week.

37920*5=189600

He types 189,600 words in a week.

The worlds two highest dams are both in Tajikistan. The rogue dam is 35 meters taller than the Nurek dam. together they are 635 meters tall. Find the height of the Nurek dam.

This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300

In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2

If at least one independent variable is between-groups and at least one is within-groups, the design is referred to as:

A variable is an object that you are trying to measure. It has two types; independent and dependent variable. An independent variable is a variable that is not affected by other variables. A dependent variable on the other hand is a variable that depends on the other variables. Suppose you want to know the quality of sleep of the students in their academic performance. The quality of sleep is the independent variable and the academic performance is the dependent variable. There are also controlled variables in an experiment. A controlled experiment is an experimental setup designed to test the hypotheses. It has one or more conditions (independent variables) and measures (dependent variables). It is necessary to change more than one variable, but all of the experimental conditions will be controlled so that only the variables being examined change and the amount or way of change is measured.

What is one six of 12 yard that equals to feet

Well,

One-sixth of 12 is 2, as 2 * 6 = 12.

We know that:
1 yd = 3 ft.

Therefore,
2 yd = 6 ft.
12 yds divided by 6 equals 2 yes; 2 yds = 1/6 of 12 yes
2 yards times 3 feet equals 6 feet, so, 1/6 of 12 yards is 6 feet

Evaluate B2 for B = 9.
a.18
b.81
c.92

Step-by-step explanation:

As you have that B = 9

And you have the expression , that means that you have to take the given number and to multiply it itself 2 times, that is:

If B^2 = 9^2 = 81
If B*2 = 9(2) = 18
