Jacob has $200 to spend on STAR WARS toys. He already purchased $75 on vehicles and new action figures will cost him $8 each. Ho

just olya [345]

Answer:

15 action figures

Step-by-step explanation:

Jacob had $200 to start off with. He spent $75 on vehicles, so we are going to subtract $75 from $200

200 - 75 = 125

He had $125 left. From the money he has left, he wants to purchase more toys. Action figures are $8 each. We will need to find how many action figures he can buy with the rest of his money. To do that, we will divide $125 by $8

125/8 = 15.625

He can buy 15 action figures with his remaining money. He will have remaining change.

I think the equation is:

8x + 125 = 200

8 gets the variable, 200 is the total, and 125 will not get the variable.

Can some one help me with this

pychu [463]

Answer:

Actually i don't know what is the wanted but now

i will find the total of the teenagers.

Step-by-step explanation:

$\frac{4000}{45\%} = \frac{x}{100\%} \\ x = \frac{4000 \times 100}{45} \\ x = 8889 \: \: teenagers$

I hope that is useful for you :)

Rosa can run 4 miles in 56 minutes.how many miles does Rosa run if she runs for 42 minutes

sergiy2304 [10]

$\bf \begin{array}{ccll}
miles&minutes\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
4&56\\
m&42
\end{array}\implies \cfrac{4}{m}=\cfrac{56}{42}\implies \cfrac{4\cdot 42}{56}=m$

Use simpson's rule with n = 10 to approximate the area of the surface obtained by rotating the curve about the x-axis. compare y

Lubov Fominskaja [6]

y = ln x , 1 <= x <= 3, about x axis and n = 10, dy/dx = 1/ x

S = (b a) ∫ 2π y √( 1 + (dy/dx) ^2) dx

so our f(x) is 2π y √( 1 + (dy/dx) ^2)

(b - a) / n = / 3 = (3-1) / 30 = 1/15

x0 = 1 , x1 = 1.2, x2 = 1.4, x3 = 1.6 ....... x(10) = 3

So we have , using Simpsons rule:-

S10 = (1/15) ( f(x0) + 4 f(x1) + 2 f)x2) +.... + f(x10) )

= (1/15) f(1) + f(3) + 4(f(1.2) + f(1.6) + f(2) + f(2.4) + f(2.8)) + 2(f(1.4) + f(1.8) + f(2.2) + f(2.6) )

( Note f(1) = 2 * π * ln 1 * √(1 + (1/1)^2) = 0 and f(3) = 2π ln3√(1+(1/3^2) = 7,276)

so we have S(10)

= 1/15 ( 0 + 7.2761738 + 4(1.4911851 +
