Circumference of a circle = 2πr
r being the radius
2πr = 4π
so r = 2
Surface area of a sphere = 4πr^2
Just plug 2 in for r and solve.
SA = 16π = 50.27

A delivery truck Is transporting boxes of two sizes: large and small. The large boxes weigh 45 pounds each, and the small boxes

Mamont248 [21]

So there would be two equations

120=x+y

and

4850=45x+35y

We can now solve for each variable

y=120-x

plug it into the second equation...

4850=45x+35(120-x)

4850=45x+4200-35x

650=10x

x=65

Now plug in X

y=120-65

y=55

They are carrying 65 big boxes and 55 small boxes.

Check

---------

120=y+x

120=55+65

120=120

Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the dista

mrs_skeptik [129]

Answer:

Option A - $\frac{0.5}{2.75}=\frac{2}{d}$

Step-by-step explanation:

Given : Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in.

To find : Which proportion can Aricela use to determine the distance, d, between her house and the park?

Solution :

The distance between her house and the park is 'd' miles.

A scale of 0.5 in. = 2 miles

The distance between her house and the park is 2.75 in.

i.e. the scale is 2.75 in. = d miles

The proportion form is

$\frac{0.5\ in}{2.75\ in}=\frac{2\ miles}{d\ miles}$

Therefore, proportion can Aricela use to determine is $\frac{0.5}{2.75}=\frac{2}{d}$ .

So, option A is correct.
