Answer:

3-9=6 and 6-10=4

Step-by-step explanation

part of b is cut by 3 as u can see above and 9 is at the bottom on which the part is cut, as for the other one 10 is the main line and is cut by 6. so u just have minus the main line aka the long line by a parallel line next to it

Answer:

The surface area of the box in terms of l is [tex]2l^2 +116/l[/tex]

Step-by-step explanation:

The length of the box = [tex]l[/tex]

The height of the box = [tex]h[/tex]

The volume of the box can be obtained by multiplying the surface area of the base by the height of the box.

The surface area of the base of the box is a square, so it will be obtained by multiplying [tex]l \times l = l^2[/tex]

hence volume = [tex]l^2 \times h =29[/tex]

Notice that we are told to give our answer in terms of l, so we will make h the Subject of the formula in the above equation.

[tex]h =29/l^2[/tex]

In the next phase, we are to find the surface area of the box.

The box has a square base, hence it will be made up of

2 squares with 4 rectangles. This is assuming the top is closed.

This means the surface area will be

[tex]2(l^2) +4 (l\times h)[/tex]

recall [tex]h = 29/l^2[/tex]

Hence, surface area =

[tex]2(l^2) +4(l \times 29/l^2)\\2l^2 +116/l[/tex]

The surface area of the box in terms of l is [tex]2l^2 +116/l[/tex]

The surface area of the closed box in terms of l only, which has the square base is,

[tex]2l^2+\dfrac{116}{l}\;\rm ft^2\\[/tex]

Volume of cuboid or box is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of cuboid or box can be given as,

[tex]V=l\times b\times h[/tex]

Here, (l) is the length, (b) is the width of the box and (h) is the height of the box.

A closed box has a square base with side length l feet and height h feet.  Therefore, the length and width will be the same.

The volume of the box is 29 cubic feet. Thus,

[tex]29=l\times (l)\times h\\h=\dfrac{29}{l^2}[/tex]

The surface area of the square base box is,

[tex]A=2l^2+4lh[/tex]

Put the value of height,

[tex]A=2l^2+4l\dfrac{29}{l^2}\\A=2l^2+\dfrac{116}{l}\\[/tex]

Hence, the surface area of the closed box in terms of l only, which has the square base is,

[tex]2l^2+\dfrac{116}{l}\;\rm ft^2\\[/tex]

Answer:

Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.

Width = 55ft

Area = 4950 sq ft

Cost = $9900

Step-by-step explanation:

Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.

You have to convert the yards to ft to add it to the other ft.

1 Yard = 3 ft

So the width is  18 yards 1 ft = 54ft + 1ft = 55ft

To calculate the  area is L x W

The length is 30 yards. Convert that to ft = 90ft

So 90 x 55 = 4950 sq ft

At $2 per sq ft, you multiply the 4950 sq ft by $2

2 x 4950 = $9900

Answer:

The expression is: [tex]-30n + 70 = -80[/tex]

Step-by-step explanation:

Given

[tex]n = 5[/tex]

Multiply both sides by 3

[tex]3 * n = 5 * 3[/tex]

[tex]3n = 15[/tex]

Subtract both sides by 7

[tex]3n - 7 = 15 - 7[/tex]

[tex]3n - 7 = 8[/tex]

Multiply both sides by -10

[tex]-10(3n - 7) = -10*8[/tex]

[tex]-30n + 70 = -80[/tex]

To verify: Substitute 5 for n

[tex]-30 * 5 + 70 = -80[/tex]

[tex]-150 + 70 = -80[/tex]

Answer:

Undetermined x=x

Step-by-step explanation:

First, you need to simplify each side by combining like terms:

(5x - 7x)(+3-4) = (2x - 4x) +1

-2x - 1 = -2x + 1 is your simplified expression.

After adding 1 to both sides, you're left with: -2x = -2x

You can divide both sides by -2, you'd get: x = x

Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.

Answer:

B

Step-by-step explanation:

We are given that the position of a particle is modeled by the function:

[tex]s(t)=2t^3-24t^2+90t+7[/tex]

And we want to find the times for which the speed of our particle is increasing.

In other words, we want to find the times for which our acceleration is positive (a(t)>0).

So first, we will find our acceleration function. We can differentiate twice.

By taking the derivative of both sides with respect to t, we acquire:

[tex]\displaystyle s^\prime(t)=v(t)=\frac{d}{dt}\big[2t^3-24t^2+90t+7\big][/tex]

Differentiate:

[tex]v(t)=6t^2-48t+90[/tex]

This is our velocity function. We can differentiate once more to acquire the acceleration function. Therefore:

[tex]\displaystyle v^\prime(t)=a(t)=\frac{d}{dt}\big[6t^2-48t+90\big][/tex]

Differentiate:

[tex]a(t)=12t-48[/tex]

If our speed is increasing, our acceleration must be positive. So:

[tex]a(t)>0[/tex]

By substitution:

[tex]12t-48>0[/tex]

Now, we can solve for t:

[tex]12t>48\Rightarrow t>4[/tex]

Therefore, the only interval for which the speed of the particle is increasing (i.e. the acceleration is positive) is for all times t>4.

So, our answer is B.

~I hope I helped you :)~

I hate math

First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)

Your equation after should be

5x + 6x - 12 - 8x + 24

Next would be addition, don't forget it's always left to right.

11x - 12 - 8x + 24

Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).

11x - 8x + 12

Next, subtract the two remaining x values.

3x + 12

And there you have it. Easy peasy.

If the case is trying to find x, just solve it like this.

3x = -12

x = 4

Step-by-step explanation:

your welcome :)

Answer:

I believe that the answer is 6  

Step-by-step explanation:

Because I got it right

Answer: False. One counter example is when x = 10.

When x = 10, we have

7x^2 = 7*10^2 = 7*100 = 700

2^x = 2^100 = 1.27 * 10^30

The result of 2^x is much larger than 700. The result is so large that we must use scientific notation to be able to fit it on the page. We could write out all the digits, but we would need 30 or more digits.

As a visual to see that 2^x will be larger at some point, I recommend graphing y = 7x^2 and y = 2^x together on the same xy grid. See the graph below. The two curves intersect at point A, which is roughly when x = 9.22; anything beyond this x value will have 2^x be larger than 7x^2.

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

We have

n = 4 scores

SS = 48

For this question, we are required to find the estimated standard error

To get this, we first solve for the variance

S² = SS/n-1

= 48/4-1

= 48/3

= 16

Then S² = 16

S = √16

S = 4

Then the estimated standard error is given by:

S/√n

= 4/√4

= 4/2

= 2.

The estimated standard error is 2.

Answer:

Erin made 5.5 dozen cookies.

Step-by-step explanation:

Total cookies made by Kim, Mary and Erin = 24 dozen cookies

Let Erin make cookies = x dozens

Mary made cookies = 2x dozens

Kim made cookies = x+2 dozens

Now, we need to find how many cookies did Erin made.

We can write:

[tex]x+2x+x+2=24[/tex]

Solving the equation we get:

[tex]x+2x+x+2=24\\4x+2=24\\4x=24-2\\4x=22\\x=22/4\\x=5.5[/tex]

So, Erin made cookies = x = 5.5 dozens

Mary made cookies = 2x =2(5.5) = 11 dozens

Kim made cookies = x+2 =5.5+2 = 7 dozens

Therefore, Erin made 5.5 dozen cookies.

Answer:

0.1039

Step-by-step explanation:

Obtain the place value of 9 in each value and choose the smallest :

1.95

9 is the first digit after the decimal point ; which is equal to 0.9 = tenth place

0.1039

9 is the 4th digit after the decimal point ; which is equal to 0.0009 = ten thousandth place

3.092

9 is the second digit after the decimal point ; which is equal to 0.09 = hundredth place

2.009​

9 is the third digit after the decimal point ; which is equal to 0.009 = thousandth place

Hence the smallest value of 9 among the options given resides in 0.1039 (ten thousandth place).
