The radius of a large sphere is 8 times the radius of a small sphere. the surface area of the large sphere is how many times the

kondaur [170]

Large sphere's radius = R,
small sphere's radius = r, R = 8r
surface area of a sphere (SA) = 4×pi×radius^2
So what we need is the SA of the larger in terms of the smaller sphere, so if:
SA (of R) = 4×pi×R^2, then plug in "8r" for "R"...
SA = 4×pi×(8r)^2 = 4×3.14×64r^2
SA = 12.57×64r^2 = 804 r^2
Therefore the SA of the larger sphere is 804 times the SA of the smaller sphere.
I hope that makes sense!

If triangle HBN ~ triangle LYR, find the value of x.

trasher [3.6K]

Answer:

x = 13

Step-by-step explanation:

BH / YL = HN / LR

28 / 21 = 3x-7 / x+11

cross-multiply:

4x + 44 = 9x - 21

-5x = -65

x = 13

Leigh bought a conical candle wax mold. The height of the mold is 18.9 inches and the radius of the inside of the top of the con

ICE Princess25 [194]

Answer:

87.28 cubic inches

Step-by-step explanation:

Leigh wants to fill the conical candle wax mold completely with candle wax.

We have to calculate the volume of the cone by the formula :

$V=\pi r^2\frac{h}{3}$

Here, V = volume

r = radius = 2.1 inches

h = height = 18.9 inches

By substituting these values given, into the formula

$V=\pi (2.1)^2(\frac{18.9}{3})$

= (27.783)π

= 87.28 inch³

Conical mold can hold 87.28 inch³ candle wax.

PLS ANSWER QUICKLY!!! 20 POINTS!!! Select the correct answer. Jim's sock drawer has two pairs of black socks, three pairs of whi

ehidna [41]

Answer: B. 11/13

Step-by-step explanation:

So he starts out with 16, and picks out 3 of those 13. This means that he now has 13 socks in total in the drawer, so therefore, the answer could only be A or B. However, what makes it B, is that if he doesn't put them back, the only way he wouldn't get a full pair is with the green pair. That is where the 11/13 comes in, as two of the socks are green, making it not a full pair. But since he has 3 more black socks, 5 more white socks, and 3 more grey socks, when you add those together you get 11

5+3+3=11

4. Break-Even Analysis

DiKsa [7]

Answer:

x = 1178 games

Step-by-step explanation:

Let the number of games = x

Let the total cost = Tc

Let the total revenue = Tr

Given the following data;

Investment = $10,000

Cost of each game = $1.50

Selling cost = $9.99

Total cost, Tc = (Cost of each game * Number of games) + Investment

Tc = 1.50x + 10000

Total revenue, Tr = Selling cost * Number of games

Tr = 9.99x

Breakeven point is when total cost is equal to total revenue;

Tc = Tr

$1.50x + 10000 = 9.99x$

$9.99x - 1.50x = 10000$

$8.49x = 10000$

$x = \frac {10000}{8.49}$

x = 1177.86 ≈ 1178 games.

<em>Therefore, the number of games that must be sold before the business breaks even is 1178 games. </em>
