Answer:

Image result for Identify the surface area of a sphere with a radius of 18 inches to the nearest tenth. Use 3.14 for π. 4,069.4 in2 8,134.2 in2 4,147.9 in2 16,201.4 in2

We can simply multiply the area of the great circle by four to find the surface area. The only thing to remember is that this only works with the great circle. It doesn't work with any other circles in the sphere. This is because any smaller circles in our sphere will not have the same radius

Total cost for bowling includes the fee for shoe rental plus the fee per game. The cost for each game increases by 4. After 3gam

valina [46]

y = 4x + 2 is the equation to find total cost y to rent shoes and bowl x games

Solution:

Given that, The cost for each game increases by 4

The Total cost for bowling includes the fee for shoe rental plus the fee per game.

Let the total cost be "y"

Let the number of games be "x"

The point slope equation can be used to describe this situtaion

$y - y_1 = m(x - x_1)$

Here $(x_1 , y_1)$ represents the cost after 3 games is $ 14

$(x_1 , y_1) = (3, 14)$

The cost for each game increases by 4. So, here m = 4

Therefore, the equation becomes,

y - 14 = 4(x - 3)

y - 14 = 4x - 12

y = 4x - 12 + 14

y = 4x + 2

So here, 2 represents the shoe rental and "x" is the number of games

Thus the required equation to find total cost y to rent shoes and bowl x games is found

Ip a solid sphere with a diameter of 0.19 m is released from rest; it then rolls without slipping down a ramp, dropping through

lubasha [3.4K]

Answer: K = (1/2) mvÂ˛ + (1/2) IĎ‰Â˛, where m is the ball mass, I is the ball's moment of inertia (2/5)mrÂ˛, and Ď‰ is the angular velocity of the ball. Because the ball rolls without slipping, it is easy to see that v=Ď‰r, or r=v/Ď‰. Then, K = (1/2)mvÂ˛ + (1/2)(2/5)mrÂ˛Ď‰Â˛ = (1/2)mvÂ˛ + (1/5)mvÂ˛ = (7/10)mvÂ˛ Setting potential at the top equal to kinetic at the bottom, mgh=(7/10)mvÂ˛ v=âš{(10/7)(gh)} = [(10/7)(9.8)(0.51)]^(1/2) = 2.672m/s

A cash register contains only five dollar and ten dollar bills. It contains twice as many five's as ten's and the total amount o

Effectus [21]

Answer:

Step-by-step explanation:

Let number of ten dollar bills be x .

So, number of five dollar bills = 2 x

Total amount of money in the cash register = 620 dollars

Amount of money in total cash as a result of five dollar bills = 2 x × 5 = 10 x dollars

Amount of money in total cash as a result of ten dollar bills = x × 10 = 10 x dollars

According to question ,

Total amount of money in the cash register = Amount of money in total cash as a result of five dollar bills + Amount of money in total cash as a result of ten dollar bills

⇒ 620 = 10 x + 10 x

⇒ 620 = 20 x

⇒ x = $\frac{620}{20}$ = 31

So, number of ten dollar bills = 31
