Your answer would be A = 444.72 Or 445

Answer:

x = 44.9

Step-by-step explanation:

This equation shown falls in the formula for z score:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Where [tex]\mu[/tex] = 62

[tex]\sigma[/tex] = 5.7

ans z = -3

So, which value corresponds to a z-score of -3???

we cross multiply and do algebra to solve for x:

[tex]-3=\frac{x-62}{5.7}\\-3*5.7=x-62\\-17.1=x-62\\-17.1+62=x\\44.9=x[/tex]

Answer: [tex]x=15[/tex]

Step-by-step explanation:

You can observe in the exercise that the equation you need to solve is:

[tex]x-5=10[/tex]

You need to find the value of the variable "x" of this equation. To do this, you need to remember the Addition Property of equality, which states that:

[tex]If\ a=b\ then\ a+c=b+c[/tex]

Knowing this, to solve for the variable "x", you must add 5 to both sides of the equation. Therefore, you get this result:

[tex]x-5+5=10+5\\x=15[/tex]

Answer:

15/28

Step-by-step explanation:

2/7 plus 1/4 plus 26 is 15/28

Answer:

Total number of eggs in basket = 56

Step-by-step explanation:

Let z be the total number of eggs

Green eggs = [tex]\frac{2}{7}[/tex] × z   ........1

Blue eggs =  [tex]\frac{1}{4}[/tex] × z    .......2

Rest of eggs = 26  ........3

The addition of 1, 2 and 3 is equal to z  

[tex]\frac{2}{7}[/tex] × z + [tex]\frac{1}{4}[/tex] + 26 = z

[tex]\frac{8z + 7 z}{28}[/tex] + 26 = z                        ∵GCF for 4 and 7 is 28  

[tex]\frac{15z}{28}[/tex]  + 26 = z

15z + (26 × 28) = 28z                ∵ multiply both sides by 28

15z + 728 = 28z

28z - 15z = 728     .......... rearranging above equation

13z = 728  ⇒   z = [tex]\frac{728}{13}[/tex]   ⇒  z = 56

Total number of eggs = z = 56

Step-by-step explanation:

To solve these kind of problems, what we have to do is find how much of 340 is 25%, and then subtract that number to the original price.

Let's give you some important information in the text:

With the information above, we can solve our problem.

First, we would need to find how much of 340 is 25%, and to do that, we would multiply 340 by 0.25:

[tex]340*0.25 = 85[/tex]

When you solve, you should get 85. But, you're not done yet, we need to find out how much the sales price is, not how much of it is discounted.

In order to find the sales price, we would get our original number (the number it originally cost), and subtract it with the amount of money it's removing (85).

In this case, we would subtract 340 by 85.

[tex]340-85=255[/tex]

Your FINAL answer should be 255

The sales price of the laptop would be $255.

582 is your answer and i already checked i hope you get it right :)

Answer: B: 582 ft2

Step-by-step explanation:  9*15= 135+36= 171 ft for the face. 171*2= 342 ft for front and back. 342+2*(15*4)=462+(6*4)=486........ and so on with all the sides.

if this is asking what I think it is, all you do is subtract 5 by 9, divide it by 2, then add the product to five. which will get you 7.

5 + 9 = 14

14/2 = 7

The answer is 7

Answer:

a) The radius of the lake to be r=10 units.

b) [tex]14\sqrt{5}[/tex] units

Step-by-step explanation:

The lake has equation: [tex]x^2+y^2=100[/tex]

We can rewrite this as [tex]x^2+y^2=10^2[/tex]

Comparing this to  [tex]x^2+y^2=r^2[/tex]

We have the radius of the lake to be r=10 units.

b)  The bridge is represented by the function  y −x = 2

This is the same as y=x+2

We substitute this into the equation of the circle to get:

[tex]x^2+(x+2)^2=100[/tex]

[tex]x^2+x^2+4x+4-100=0[/tex]

[tex]2x^2+4x-96=0[/tex]

[tex]x^2+2x-48=0[/tex]

[tex](x+8)(x-6)=0[/tex]

[tex]x=-8,x=6[/tex]

When x=8, y=2(8)+2=18

When x=-6, y=2(-6)+2=-10

The length of the bridge is the distance between the points (8,18) and (-6,-10)

[tex]=\sqrt{(8--6)^2+(18--10)^2}[/tex]

[tex]=\sqrt{196+784}[/tex]

[tex]=\sqrt{196+784}[/tex]

[tex]=\sqrt{980}[/tex]

[tex]=14\sqrt{5}[/tex]

Answer:

68

Step-by-step explanation:

Let x be the measure of one of the angles of the triangle

Two of the angles have the same measure, so another angle is x

The third is 12 degrees more, x+12

The sum of the three angles of a triangle is 180

x+x+x+12 = 180

Combine like terms

3x+12 = 180

Subtract 12 from each side

3x+12-12 = 180-12

3x = 168

Divide by 3

3x/3 = 168/3

x = 56

x=56

x=56

x+12 = 56+12 = 68

The largest angle is 68

45 - 18 = 27

About 27 mintues

Given that you and the chess teacher have been playing the game for 18 minutes and you need to win the game in less than 45 minutes, you need to subtract the time you have already spent playing from the total time allowed. So, 45 minutes (total time) - 18 minutes (time spent) = 27 minutes. You have 27 minutes left to win the chess game and enter the chess club.

The question is asking how much time you have left to win the chess game in order to make it into the chess club, given that you and the chess teacher have been playing the game for 18 minutes, and you need to win the game in less than 45 minutes. This translates to a mathematical problem of subtraction.

To find out how much time you have left, subtract the time you have already spent playing from the total time allowed. This would be 45 minutes (total time) - 18 minutes (time spent).

So, 45 minutes - 18 minutes = 27 minutes

.

You have 27 minutes to win the chess game and enter the chess club.

The unit rate, or the number of acres the workers can plant in one day, is calculated by dividing the total number of acres (3/5) by the number of days worked (5/6). The result is 18/25 acres per day, or approximately 0.72 acres per day.

In this example, we need to find out how many acres the workers plant in one day, also known as the unit rate.

To calculate this, we divide the total amount of acres (3/5) by the total number of days taken (5/6).

So the formula would be: (3/5) ÷ (5/6) = (3/5)*(6/5) = 18/25.

So, the unit rate in acres per day for the group of workers is 18/25 acres/day, which means they plant approximately 0.72 acres per day.

Answer: g(x)=12x^2+8

Step-by-step explanation:

original function f(x)=3x^2+2

Now to stretch function vertically and rename to g(x) we just multiply the function by 4;

g(x)=4(3x^2+2)=12x^2+8

Any questions feel free to ask. Thanks

The equation of the function f(x) after stretching is g(x) = 12x² + 8.

A function is a law that relates a dependent and an independent variable.

The function given is

F(x) =  3x²+2

For when a function is vertically stretched

F'(x) = k .F(x)

k >1

here it is given that k = 4

The equation becomes

g(x) = 4( 3x²+2 )

g(x) = 12x² + 8

Step-by-step explanation:

The actual area of the playground is determined by converting the scale drawing dimensions to real-life measurements using the provided scale, resulting in a playground area of 972 square feet.

Justin has created a scale drawing of a playground using the scale 2 inches: 3 feet. To find the actual area of the playground, we first convert the dimensions of the drawing to real-life dimensions. The scale factor is found by dividing the scale's drawing unit by the real unit. This gives us a factor of 1 inch being equivalent to 1.5 feet since 2 inches represent 3 feet (2 inches / 3 feet = 1 inch / 1.5 feet).

The drawing dimensions are 18 inches by 24 inches. We multiply each dimension by our conversion factor (1.5 feet per inch) to get the real-life measurements:

To find the actual area, we multiply the length by the width:

Area = length * width = 27 feet * 36 feet = 972 square feet

The actual area of the playground is 972 square feet.

Answer:

Step-by-step explanation:

C = R/1.8 - 273

C + 273 = R/1.8

1.8 * (C + 273) = R

1.8 can also be read as the fraction 9/5.

9/5 * (C + 273) = R

Thus your answer is B. Hope I helped!

So, if you add it all up it would be...

1.8 which could also be in the fraction form of 9/5 and 9/5 would be basically C.

So, even though C has 5/9 in the front that wouldn't be the case. It would be the one in parentheses we would be focusing on. So, the answer all together would be C.

Step-by-step explanation:

We assume here that the system of equations consists of two equations in two variables. If there are more equations in more variables, the general approach is the same.

A "solution" to a system of equations is a set of variable values that satisfies all equations of the system simultaneously. A table for one equation will generally list sets of variable values that satisfy that equation. When the same set of values appears in the table for each of the equations, then that set of values is the solution.

[tex]m + 23[/tex]

EXPLANATION

The given expression is

[tex]m - 13 + 42 - 6[/tex]

We regroup the numerical parts to get;

[tex]m + 42 - 6 - 13[/tex]

Now let us simplify the negative numbers.

[tex]m + 42 - 19[/tex]

We now subtract 19 from 42 to get;

[tex]m + 23[/tex]

We can't simplify further

Hence the simplest form is:

[tex]m + 23[/tex]

The equality that is graphed on the line is 2(m-3)+7>11 (A).

The correct inequality graphed on the number line is option C: [tex]\(2(m-3)-7 \leq 11\)[/tex].

To determine the correct inequality graphed on the number line, let's analyze the highlighted region (5 to 10) and compare it with the given options.

The highlighted region indicates values greater than 5. Now, testing each option:

A. [tex]\(2(m-3)+7 \geq 11\)[/tex]:

[tex]\[2(m-3)+7 \geq 11\][/tex]

[tex]\[2m - 6 + 7 \geq 11\][/tex]

[tex]\[2m + 1 \geq 11\][/tex]

[tex]\[2m \geq 10\][/tex]

[tex]\[m \geq 5\][/tex]

B. [tex]\(2(m+3)+7 \geq 11\)[/tex]:

[tex]\[2(m+3)+7 \geq 11\][/tex]

[tex]\[2m + 6 + 7 \geq 11\][/tex]

[tex]\[2m + 13 \geq 11\][/tex]

[tex]\[2m \geq -2\][/tex]

[tex]\[m \geq -1\][/tex]

C. [tex]\(2(m-3)-7 \leq 11\)[/tex]:

[tex]\[2(m-3)-7 \leq 11\][/tex]

[tex]\[2m - 6 - 7 \leq 11\][/tex]

[tex]\[2m - 13 \leq 11\][/tex]

[tex]\[2m \leq 24\][/tex]

[tex]\[m \leq 12\][/tex]

D. [tex]\(2(m+3)-7 \leq 11\)[/tex]:

[tex]\[2(m+3)-7 \leq 11\][/tex]

[tex]\[2m + 6 - 7 \leq 11\][/tex]

[tex]\[2m - 1 \leq 11\][/tex]

[tex]\[2m \leq 12\][/tex]

[tex]\[m \leq 6\][/tex]

Therefore, the correct inequality graphed on the number line is option C: [tex]\(2(m-3)-7 \leq 11\)[/tex].

The order from least to greatest would be first 210%, 43/20, then 2.2222

To order the numbers, they were first converted to decimals: 210% to 2.10, 43/20 to 2.15, and 2.2 (repeating) is slightly more than 2.2. Placing these in order yields: 2.10, 2.15, 2.2 (which includes 2.2 repeating).

To order the given numbers from least to greatest, we first need to convert all of them to the same format. We have one in percentage (210%), two decimals (2.2 and 2.2 repeating), and a fraction (43/20).

Now we can easily compare these numbers:

As 2.2 (repeating) is marginally larger than 2.2 but essentially they can be considered as equal for comparison. Hence, the ordered list from least to greatest is: 2.10, 2.15, 2.2 (or 2.2 repeating).

Step-by-step explanation:

Answer:

750 ft^3

Step-by-step explanation:

Given that the cones are similar, the first step would be to determine their linear scale factor; That is the ratio of their radii;

[tex]\frac{RadiusB}{RadiusA}=\frac{30}{12}=2.5[/tex]

The next step is to determine the volume scale factors. Since the linear scale factor is 2.5, the volume scale factor would be;

volume scale factor = (linear scale factor)^3

                                 = 2.5^3 = 125/8

The volume of Cone B will thus be;

volume of Cone A * volume scale factor = 48 * 125/8 = 750 ft^3

I would say B and D are correct.
