1. we suppose 2 variables a and b.

 we find that b=5a/6

2. One more variable c

we find c=13a/24

3. a must be a multiple of 24 and perimeter is 44*a/6 = 176a/24

Answer: 10000

Step-by-step explanation: That is as close to ten thousand as you can get

Answer:

Step-by-step explanation:

Arithmetic mean is the average of the numbers.

Formula we use is,

→ Mean = (x + y)/2

a) 40 and 60 = ?

→ (40 + 60)/2

→ 100/2 = 50

Thus, the mean is 50.

b) -60 and -20 = ?

→ (-60 - 20)/2

→ -80/2 = -40

Thus, the mean is -40.

c) (7/3) and (11/3) = ?

→ ((7/3) + (11/3))/2

→ (18/3)/2

→ 6/2 = 3

Thus, the mean is 3.

Answer:

The right angle's vertex.

Step-by-step explanation:

A right angle is 90 degrees. The vertex is at the middle of the angle, so that point is used to draw a segment in the middle of the right angle.

Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) cups of lemonade from the rest of the money.

Here we have,

Total money to spend= $40

Admission price= $20

Sandwich= $5

Add all expenses to find the money spent by Money Marilyn.

Total expense= admission price + sandwich

Total expense = $20 + $5 = $25

Amount left with her= $40-$25 = $15

The number of cups when each cup's cost is $3

Total lemonade(x) = $15/$3 = $5

In an equality,

Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) lemonades from the rest of the money.

The change for the day is 10 1/4

In this problem, we are expected to calculate the change in the price of a particular stock

Given that the days high is 80 3/4

and also that the days low is 70 1/2

we can calculate the change by subtracting the days low from the days high

i.e 80 3/4- 70 1/2= 323/4-141/2= (323-282)/4= 41/4

hence the change for the day is 41/4 =10 1/4

Also we can calculate the percentage change as

%change = (high-low)/low*100

%change= 80 3/4- 70 1/2/70 1/2*100= 41/4/70 1/2 *100

%change= 41/4*2/141*100

%change= 0.00145=0.145%

The cost of the Coca-Cola can will be $1 in the year 2000.

Given that the cost of a can of Coca-Cola can in 1960 = $0.10

The function which models the cost of a Coca-Cola by year 't' is

c(t) =   [tex]0.10e^{0.0576t}[/tex].

Here, 't' denotes the number of years since 1960.

c(t) is an exponential function.

We have to find the year in which the cost of a can will be $1.

So substitute c(t) = 1, we get,

  1 =   [tex]0.10e^{0.0576t}[/tex]

⇒ [tex]10 = e^{0.0576t}[/tex]

We have, [tex]ln(e^x) = x[/tex] .

Taking logarithm on both sides, we get,

log(10) = 0.0576t

⇒  [tex]t=\frac{ln(10)}{0.0576}[/tex]  = 39.97 ≈ 40 years .

Thus the cost of a can of Coca-Cola will be $1 in the year, 1960 + 40 = 2000.

The question was incomplete. Find the complete question at:

Three subsystems are reliability-wise in series and make up a system. Subsystem 1 has a reliability of 99.5%, subsystem 2 has a reliability of 98.7% and subsystem 3 has a reliability of 97.3% for a mission of 100 hours.

We suppose that the system consists of one operating series subsystem, an identical stand-by subsystem, and a switch. Each subsystem consists of N components.

When the operating subsystem fails, the spare is put in motion by the switch immediately. The failed subsystem is restoring or changing the failed component. Because of the memoryless property of the exponential distribution of components lifetime, the renewal of a failed element means the renewal of the whole subsystem. We assume that there is a single repair facility. A renewal time is a random variable having distribution depending on a failed component. We suppose that the lengths of restoring periods of components are represented by identical copies of nonnegative random variables.

Step-by-step explanation:

but it can be a cent off, so it might be wrong.

It lies in the quadrant IV.

Since we know that a full circle is broken into four parts known as quadrants into regions of π/2.Since quadrant  1 ranges from 0 to π/2,  quadrant 2 ranges from π/2 to π, then quadrant 3 ranges from π to 3π/2, and at last quadrant 4 ranges from 3π/2 to 2π.

And we know 2π is equal to approx  6.28 radians,  so each quadrant will have  2π/ 4 = π2  ≈1.57 radians

So for angle  -7 it will be =  −7/(π/2) ≈−4.45.

Answer:

m = -4

Step-by-step explanation:

We are given the points (-7, -2) and (-2, -22), and we want to write the slope of the line.

The slope (m) can be calculated from two points using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

We already have everything we need to calculate the slope, however, let's label their values to help avoid any confusion and mistakes for later.

[tex]x_1=-7\\y_1=-2\\x_2=-2\\y_2=-22[/tex]

Now, substitute these values into the formula. Remember that the formula has subtraction, and we're dealing with negative numbers here.

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-22--2}{-2--7}[/tex]

Simplify.

m=[tex]\frac{-22+2}{-2+7}[/tex]

Add.

m=[tex]\frac{-20}{5}[/tex]

Divide.

m = -4

The slope of the line is -4.

1. The correct arithmetic operation with parentheses is 8 + (3 - 2) × 9 = 17

2. The correct arithmetic operation with parentheses is 28 ÷ (4 + 3) × (4 + 3) = 28

3. The correct arithmetic operation with parentheses is  5 × (3 + 2) × 6 ÷ 3

4. The correct arithmetic operation with parentheses is 6 × (9 - 4) + (3 - 3) × 4

5. The correct arithmetic operation with parentheses is (5 × 3) + (2 × 6) ÷ 3 = 19

6. the correct arithmetic operation with parentheses is 5 × [3 + 2 × (6 ÷ 3)] = 35

Arithmetic operations are mathematical operations that involve multiplication, division , addition and subtraction.

Arithmetic operations follow the rule of BODMAS where

How to insert parentheses in the appropriate places:

Since the expression evaluates to 17, we put a parentheses between 3 and - 2. So,

8 + (3 - 2) × 9 = 8 + 1 × 9

= 8 + 9

= 17

So, the correct arithmetic operation with parentheses is 8 + (3 - 2) × 9 = 17

Since the expression evaluates to 28, we a parentheses between 4 and + 3. So,

28 ÷ 4 + 3 × 4 + 3 = 28 ÷ (4 + 3) × (4 + 3)

= 28 ÷ 7 × (4 + 3)

= 4  × 7

= 28

So, the correct arithmetic operation with parentheses is 28 ÷ (4 + 3) × (4 + 3) = 28

Since the expression evaluates to 50, we put a parentheses between 3 and + 2. So,

5 × 3 + 2 × 6 ÷ 3 = 5 × (3 + 2) × 6 ÷ 3

= 5 × 5 × 2

= 50

So, the correct arithmetic operation with parentheses is  5 × (3 + 2) × 6 ÷ 3

Since the expression evaluates to 30, we put a parentheses between 9 - 4 and 3 - 3. So,

6 × 9 - 4 + 3 - 3 × 4 = 6 × (9 - 4) + (3 - 3) × 4

= 6 × 5 + 0 × 4

= 30 + 0

= 30

So, the correct arithmetic operation with parentheses is 6 × (9 - 4) + (3 - 3) × 4

Since the expression evaluates to 19, we put a parentheses between 2 and 6, and also 5 and 3. So,

5 × 3 + 2 × 6 ÷ 3 = (5 × 3) + (2 × 6) ÷ 3

= 15 + 12 ÷ 3

= 15 + 4

= 19

So, the correct arithmetic operation with parentheses is (5 × 3) + (2 × 6) ÷ 3 = 19

Since the expression evaluates to 35, we put a parentheses between 6 and 3 and also both 3's. So,

5 × 3 + 2 × 6 ÷ 3 = 5 × [3 + 2 × (6 ÷ 3)]

= 5 × [3 + 2 × 2]

= 5 × [3 + 4]

=  5 × 7

= 35

So, the correct arithmetic operation with parentheses is 5 × [3 + 2 × (6 ÷ 3)]  = 35
