Answer:

I think its 144

Step-by-step explanation:

they both earn 66 now 66+6= 72 but it says twice as much so 72 × 2= 144

Answer: The answer is $20 and $46

Step-by-step explanation:

(6+2x)+x=66

6+3x=66

3x=60

X=20

2(20)+6= 46

Answer:

[tex]Height = 12cm[/tex]

[tex]Radius = 6cm[/tex]

Step-by-step explanation:

Given

Represent volume with v, height with h and radius with r

[tex]V = 432\pi[/tex]

Required

Determine the values of h and r that uses the least amount of material

Volume is calculated as:

[tex]V = \pi r^2h\\[/tex]

Substitute 432π for V

[tex]432\pi = \pi r^2h[/tex]

Divide through by π

[tex]432 = r^2h[/tex]

Make h the subject:

[tex]h = \frac{432}{r^2}[/tex]

Surface Area (A) of a cylinder is calculated as thus:

[tex]A=2\pi rh+2\pi r^2[/tex]

Substitute [tex]\frac{432}{r^2}[/tex] for h in [tex]A=2\pi rh+2\pi r^2[/tex]

[tex]A=2\pi r(\frac{432}{r^2})+2\pi r^2[/tex]

[tex]A=2\pi (\frac{432}{r})+2\pi r^2[/tex]

Factorize:

[tex]A=2\pi (\frac{432}{r} + r^2)[/tex]

To minimize, we have to differentiate both sides and set [tex]A' = 0[/tex]

[tex]A'=2\pi (-\frac{432}{r^2} + 2r)[/tex]

Set [tex]A' = 0[/tex]

[tex]0=2\pi (-\frac{432}{r^2} + 2r)[/tex]

Divide through by [tex]2\pi[/tex]

[tex]0= -\frac{432}{r^2} + 2r[/tex]

[tex]\frac{432}{r^2} = 2r[/tex]

Cross Multiply

[tex]2r * r^2 = 432[/tex]

[tex]2r^3 = 432[/tex]

Divide through by 2

[tex]r^3 = 216[/tex]

Take cube roots of both sides

[tex]r = \sqrt[3]{216}[/tex]

[tex]r = 6[/tex]

Recall that:

[tex]h = \frac{432}{r^2}[/tex]

[tex]h = \frac{432}{6^2}[/tex]

[tex]h = \frac{432}{36}[/tex]

[tex]h = 12[/tex]

Hence, the dimension that requires the least amount of material is when

[tex]Height = 12cm[/tex]

[tex]Radius = 6cm[/tex]

Answer:

1279

Step-by-step explanation:

You take 2204 and subtract 925 to give you the number of boys ehich is 1279

Answer:

1279

Step-by-step explanation:

total amount of students: 2,204

Total Amount of Girls: 925

Total Amount of Boys: ?

2,204 - the total amount of girls which is 925 which is = to 1279 which is the total amount of boys i think

Answer:

x=.5

Step-by-step explanation:

First, you need to isolate the variable term, so you have to move -5 over to the other side. Since it is subtraction on this side, you add 5 to both sides to cancel out the -5, and add it to the other side.

Now we have 10x=5. To solve for the variable, we have to divide by the number in the variable term. In this case, it is 10. 10/10 is 1, so now x is alone. We have to do the same thing on the other side. 5/10 is .5.

That's the answer! It's x=.5!

"Not putting it here"

The cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.

Percentage increase is the amount added to the initial value in the percentage part.

Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%.

Let the cost of the necklace before tax is x dollars. Now, the 108% of the x is $9.18. Thus,

[tex]x\times\dfrac{100+8}{100}=9.18\\x=\dfrac{9.18\times100}{108}\\x=8.5[/tex]

Hence, the cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.
