Answer:

48,000

Step-by-step explanation:

Set up a proportion: $\frac{15}{100} = \frac{x}{320000}$
Cross multiply, then divide in steps 3 and 4
15 × 320,000 = 4,800,000
4,800,000 ÷ 100 = 48,000

I hope this helps!

Answer:

48,000

Step-by-step explanation:

320,000÷100=3200

Kathy is baking cakes. Each cake requires 1/12 of a teaspoon of vanilla,and she has 3/4 of a teaspoon,how many cakes can she bak

scZoUnD [109]

Answer:

Step-by-step explanation:

You want to find out how how 1/12 of a tsp go into 3/4 of a tsp so.......

You do 3/4 divided by 1/12 but when dividing fractions you flip over the second fraction and change the division operation to a multiplication operator so....

It will 3/4 x 12/1 and this will give you 36/4

36 divided by 4 is 9

So....

Kathy can bake 9 cakes.

Hope this helps!

Johnathan can jog 3 2/5 miles in 7/8 hour. Found his average speed in miles per hour

choli [55]

3 2/5 = 17 / 5 ;
(17/5) ÷ (7/8) = (17/5) × (8/7) = 136/35 = 3.88 miles per hour ;

Find the area of the part of the sphere x2 + y2 + z2 = 100z that lies inside the paraboloid z = x2 + y2.

vekshin1

$x^2+y^2+z^2=100z\iff x^2+y^2+(z-50)^2=50^2$

The surface of interest can be parameterized by

$\mathbf r(u,v)=\begin{cases}x(u,v)=50\cos u\sin v\\y(u,v)=50\sin u\sin v\\z(u,v)=50(\cos v+1)\end{cases}$

with $0\le u\le2\pi$ and $0\le v\le\arccos\dfrac{49}{50}$ .

The area of the surface $S$ is given by the surface integral

$\displaystyle\iint_S\mathrm dA=\iint_T\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv$

We have

$\|\mathbf r_u\times\mathbf r_v\|=50^2\sin v$

so the area is given by the double integral

$\displaystyle50^2\int_{u=0}^{u=2\pi}\int_{v=0}^{v=\arccos(49/50)}\sin v\,\mathrm dv\,\mathrm du=100\pi$

The contents of the fuel tank of a car can be modeled by the function g(x)= -0.04x + 10, where x is in miles driven and g(x) rep

Vlad [161]

The answer is B.4. It is 4 because you have to multiply -0.04 x 150 since the x after -0.04 represents miles driven which was 150 and then add 10 which then you get 4
