​

Answer:

each side is 12 cm

Step-by-step explanation:

This is a simple equation, since a square is equal an all 4 sides, all you have to do it divide 72 by 4 to get your answer.

Answer:

Step-by-step explanation:

Total number of snacks sold by 8th grade class = 30

Percentage of a particular snack sold = [tex]\frac{\text{Number of particular snack sold}}{\text{Total number of all snacks sold}} \times 100[/tex]

Percentage of cookies sols = [tex]\frac{6}{30}\times 100[/tex] = 20%

Percentage of cheese sticks sold = [tex]\frac{8}{30}\times 100[/tex]

                                                         = 26.67%

Percentage of  chips sold = [tex]\frac{12}{30}\times 100[/tex]

                                           = 40%

Percentage of water sold = [tex]\frac{4}{30}\times 100[/tex]

                                          = 13.33%

Answer:

Heidi wants to compute:

17 - 9.

First, she adds to get 10, (we want to subtract 10, this is easier than subtracting 9) then she can do:

17 - 9 + 0

adding zero does not change the sum

1 - 1 = 0

then:

17 - 9 + 0 = 17 - 9 + 1 - 1

Now we can do:

17 - 9 - 1 + 1

17 - (9 + 1) + 1

17 - 10 + 1

(17 - 10) + 1

7 + 1 = 8

Then, first she needs to add -1, in order to subtract 10, and then she must add 1. As we added a number and its inverse, in total we added zero, so the sum did not change, but was easier to compute.

Then, you need

Answer:

a. [tex]Probability = 0.97735[/tex]

b. [tex]Probability = 0.92294[/tex]

c. [tex]P(At\ Least\ One) = 1[/tex]

No, it is not unusual if at least 1 lives up to 3.

Step-by-step explanation:

Given

Represent the probability that a 2 year old snake will live to 3 with P(Live);

[tex]P(Live) = 0.98861[/tex]

Solving (a): Probability that two selected will live to 3 years.

Both snakes have a chance of 0.98861 to live up to 3 years.

So, the required probability is:

[tex]Probability = P(Live)\ and\ P(Live)[/tex]

[tex]Probability = 0.98861 * 0.98861[/tex]

[tex]Probability = 0.9773497321[/tex]

[tex]Probability = 0.97735[/tex] --- Approximated

Solving (b): Probability that seven selected will live to 3 years.

All 7 snakes have a chance of 0.98861 to live up to 3 years.

So, the required probability is:

[tex]Probability = P(Live)^n[/tex]

Where [tex]n = 7[/tex]

[tex]Probability = 0.98861^7[/tex]

[tex]Probability = 0.92294324145[/tex]

[tex]Probability = 0.92294[/tex] --- Approximated

Solving (c): Probability that at least one of seven selected will not live to 3 years.

In probabilities, the following relationship exist:

[tex]P(At\ Least\ One) = 1 - P(None).[/tex]

So, first we need to calculate the probability that none of the 7 lived up to 3.

If the probability that one lived up to 3 years is 0.98861, then the probability than one do not live up to 3 years is 1 - 0.98861

This gives:

[tex]P(Not\ Live) = 0.01139[/tex]

The probability that none of the 7 lives up to 3 is:

[tex]P(None) = P(Not\ Live)^7[/tex]

[tex]P(None) = 0.01139^7[/tex]

Substitute this value for P(None) in

[tex]P(At\ Least\ One) = 1 - P(None).[/tex]

[tex]P(At\ Least\ One) = 1 - 0.01139^7[/tex]

[tex]P(At\ Least\ One) = 0.99999999999997513055642436060443621[/tex]

[tex]P(At\ Least\ One) = 1[/tex] ---- Approximated

No, it is not unusual if at least 1 lives up to 3.

This is so because the above results, which is 1 shows that it is very likely for at least one of the seven to live up to 3 years

Step-by-step explanation:

Answer:

m<L.F.M = 50

Step-by-step explanation:

So we know that the m<F.M.L = 90 and m<F.M.P = 90 so...

3x- 1 + 2x + 6 = 90 (collect like terms)

5x + 5 = 90 (subtract 5 on both sides)

5x = 85 (divide by 5 on both sides)

x = 17

Plug in to (3x-1)

3(17) - 1 = m<L.F.M

50 = m<L.F.M

Hope this helps!!

Answer:

I'm pretty sure its 11.5

Answer:

11.5 mi.

Step-by-step explanation:

First, you figure out how much miles Sally has gone by walking.

6.5-4=2.5 mi.

You use the distance formula: d(distance)=r(rate)xt(time)

2.5 mi.=Rx1 hr.

rate=2.5 mi/hr.

To figure out how many miles Sally will be from her house after two more hours of walking, you use the distance formula again.

d=2.5mi/hrx2 hr.

d=5.0 mi(2.5x2)

6.5mi+5.0mi=11.5 mi total

I would say that the tree is 12 feet high.

And to find out the answer you could use the quadratic formula :)

Step-by-step explanation:

Answer:

The numbers are 9 + 11 + 13 + 15.

Step-by-step explanation: The equation for this is simple.

Take x as the smallest number of the 4 numbers. The second number would be x +2, third number is x+4, and the fourth number is x+6. you add these together, and you get: 4x +12 = 48, you then solve this as a linear equation. 48-12 = 36. Then you divide by 4, which gives you 9 as the smallest number of the 4 numbers. Remember that the second number is  9+2=11, third is 9+4=13, and the fourth is 9+6=15. If you add these together you get 9+11+13+15=48.

Answer:

26.83inches

Step-by-step explanation:

Area of the square mirror is expressed as A = L²

L is the side length of the square mirror

Given

Area = 720in²

Get the length

720 = L²

L = √720

L = 26.83

Hence the length of wood trim needed to go around the entire mirror is 26.83inches

Answer:

-169

Step-by-step explanation:

An Arithmetic Combination states that  two functions f and g at any x i.e in the domain of both f and g, with one exception.

The quotient  is not defined at values of x, where g is equal to 0 or we can say that both the functions must be defined at a point for the combination to be defined.

Given: f(x) = 3-2x and g(x) =  

Then, using arithmetic combination of function definition:

                ......[1]

Now, first find the value of f(9) and g(8) ;

f(8) =3-2(8) = 3-16 = -13 and

Substitute these in equation [1] ;

Therefore, the value of (f/g)(8) is; -169

Answer:

8 over 3

Step-by-step explanation:

Use

Y2 - y1 over x2 - x1 slop formula

Answer:

the slope in fraction form is 8/3, in integer form is 8.

Step-by-step explanation:

use the x coordinates for the run and the y coordinates for the rise. To find the rise you use the y coordinates -6 and 2, and think about how many spaces away they are on the coordinate plane by adding them both like they are positive. 6 + 2 = 8. To find the run, subtract 7 from 4 which equals 3. So, there you have the rise over run = 8/3 or in integer form, 8.

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. :) Stay safe and please mark brainliest!

Answer:

After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]

Step-by-step explanation:

We need to solve the equation: [tex](45x-7)4x=57[/tex]

Solving:

[tex](45x-7)4x=57[/tex]

Multiply 4x with terms inside the bracket

[tex]180x^2-28x=57[/tex]

[tex]180x^2-28x-57=0[/tex]

We need to solve above equation to find value of x

Using quadratic formula for finding value of x: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

We have a=180, b=-28 and c=-57

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-28)\pm\sqrt{(-28)^2-4(180)(-57)}}{2(180)}\\x=\frac{28\pm\sqrt{784+41040}}{360}\\x=\frac{28\pm\sqrt{41824}}{360}\\x=\frac{28\pm204.51}{360}\\x=\frac{28+204.51}{360} \ or \ x=\frac{28-204.51}{360}\\x=0.645 \ or \ x = -0.490[/tex]

Values of x are [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]

So, After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
