What is the value of st ÷ (6r) if r = 5, s = 32, and t = 45?

Answers

Answer 1
Answer:

Answer: The answer is 48.

Step-by-step explanation:  The given expression is

E=st/6r.

we are given to solve the above expression is the value of r is 5, the value of s is 32 and the value of t is 45.

The solution is as follows:

E\n\n=st/6t\n\n=(st)/(6r)\n\n=(32* 45)/(6* 5)\n\n=16* 3\n\n=48.

Thus, the required value is 48.
Answer 2
Answer: st ÷ 6r
(32)(45) ÷ 6(5)
1440 ÷ 30
48

The end zone of a football field is 10 yards deep and 53 yards across. Between the two end zones is the playing field, which is 100 yards long and 53 yards wide. What is the length of the diagonal from the back of one end zone to the back of the other?

Answers

When you put the pieces of the field together, you have a rectangle that's 53 yards
wide and 120 yards long.

When you draw the diagonal, it divides the field into two right triangles.Each one
has legs with lengths of 120 yards and 53 yards.  The diagonal of the field is the
hypotenuse of both right triangles.

(120)² + (53)² = (the hypotenuse)²

14,400 + 2,809 = (the hypotenuse)²

17,209 = (the hypotenuse)²

The diagonal (hypotenuse) = √17,209 = 131.183... yards (rounded)

a data set has a variance of 88.what is the standard deviation of the data set? round to the nearest tenth

Answers

The standard deviation is equal to the square root of the variance:

\sigma =\sqrt { Variance }

Therefore:

\sigma =\sqrt { 88 } \n \n \therefore \quad \sigma \approx 9.4

Compute the amount of interest earned in the following simple interest problem. A deposit of $100 at 8% for 20 years = _____. $1.60 $16.00 $160.00 $1,600.00

Answers

Answer:

C. $160.

Step-by-step explanation:

We are asked to find the amount of simple interest earned from a deposit of $100 at 8% for 20 years.  

We will use simple interest formula to solve our given problem

I=Prt, where,

I=\text{Amount of interest},  

P=\text{Principal amount},  

r=\text{Interest rate in decimal form},  

T=\text{Time in years}.

Let us convert our given interest rate in decimal form.

8\%=(8)/(100)=0.08

Upon substituting our given values in above formula we will get,

I=100*0.08*20

I=160

Therefore, the amount of interest earned is $160 and option C is the correct choice.
Initial deposit = 100 dollars
Interest = 8% = 0.08
time of deposit - 20 years or 240 months.
Annual Rate :
=> 100 dollars * .08 = 8 dollars per year
=> 8 * 20 = 160 dollars for 20 years.
