Answer:

0.006

Step-by-step explanation:

Answer:

Explanation:

611 or 6÷11=0.545454545....

The hundredth position is two positions to the right of the decimal point. For this problem it is the 4:

0.545454545....

To round to the nearest hundredth you must look at the digit in the position immediately to the right of the digit in the hundredth place, which is the 5 in the thousandth place:

0.545454545....

If the digit to the right is greater than or equal to 5 you add 1 to the digit you are rounding to and make everything to the right 0.

If the digit to the right is less than 5 you add keep the digit you are rounding to the same and make everything to the right 0.

In this problem the digit to the right is a 5 so we add 1 to the digit we are rounding to and make everything to the right 0.

0.545454545....=0.550000000....=0.55

Answer:

2 and 10

Step-by-step explanation:

We will assume to numbers represented by x and y.

From the question, we can write the following :

sum = x + y

difference = x - y

product = xy or x*y

Since we have two unknowns, general rule of thumb is that we require

2 equations to solve for them.

Using the ratio, of  sum:  difference and sum : product,

I can form these 2 equations:

(x + y) / (x -y) = 3/2  (1)

(x + y) / (x*y) = 3/5 (2)

In (1),

we cross multiply and do some tidying we will get

x = 5y

In (2),

we have 5x + 5y = 3x*y

We can then substitute x = 5y into (2) and get the following

5*5y + 5y = 3*5y*y

30y = 15y^2

2y = y^2

y^2 - 2y = 0

After factorization,

y(y - 2) = 0

you will have to options either use y = 0 or y = 2

If we use 2, then using equation (1),

we can solve for x which is 10.

Answer:

2 , 10

Step-by-step explanation:

(x+y) / (x-y) = 3/2   ..(1)

3x-3y = 2x+2y

x = 5y

(x+y) / xy = 3/5

(5y+y) / (5y*y) = 3/5

6y/5y² = 3/5

15y² = 30y

y = 2

x = 10

check: (2+10) : (10-2) : (10*2) = 12 : 8 : 20 = 3 : 2 : 5

Answer:

46° Fahrenheit

Step-by-step explanation:

Center line can be said to be the X double bar. X double bar is the average value we have across all components we're considering. In this question, the X double bar is already given as 960 bottles (if you multiply 120 days by 8 bottles per day) and that it is 46 degrees Fahrenheit.

As such, there exist no reason to want to or have to solve for anything since it's already given.

Therefore the Centre line is 46 degrees Fahrenheit, same as what is given in the question.

Answer:

18%

Step-by-step explanation:

Answer:

m = 2, c = 1

Explanation: In the y = mx + b (or y = mx + c) format, the m is the slope of the line and the c/b is the y-intercept, or where the line crosses the y-axis. If we substitute the information from the given equation, y = 2x + 1, into the general formula, we know that the m is 2 and c is 1.

Answer:10

Step-by-step explanation:

In fraction,

(1/100)^(-1/2)

Equivalent to 1/((1/100)^(1/2))

Power 1/2 is basically square root

So we have 1/(1/10) after applying square root to 1/100

so final step

1 divide (1/10) = 10

Answer:

The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions

Answer:

Step-by-step explanation:

r = 0.9 m

h = 3.6 m

Area of two circle faces combined: 2*π(0.9)^2 = 1.62π

Lateral area = circumference*height = 2π(0.9)(3.6) = 6.48π

Surface Area = 1.62π + 6.48π = 8.1π m sq.

Answer:

w = 1/4

Step-by-step explanation:

Distribute:

-3w + 9 - 9w -9 = 4w + 8 -12

Combine like terms:

-16w = -4

w = 1/4

Answer:

w=1/4

Step-by-step explanation:

-3w+9-9w-9=4w+8-12

-12w=4w+8-12

-12w=4w-4

-12w-4w=-4

-16w=-4

w=-4/-16

w=1/4

Answer:

Step-by-step explanation:

All of its side are equal so it is an equilateral triangle. And as we all know an Equilateral triangle has 3 equal angles.

So based on this we can solve it using algebra,

[tex]3x + 3x + 3x = 180[/tex]

So using this we can find the value for x

[tex]9x = 180 \\ x = \frac{180}{9} \\ x = 20[/tex]

This is your answer hope it helps :)
