Are is equal to the length times width so what times what would give you 121 and that's how you get the answer to that problem or any area perimeter problem

Keep in mind:  area of a square = (side length)^2
                        perimeter of a square = 4(side length)

Use the first formula to determine the side length (find the sq. rt. of 121 m^2).
Then use the second formula to find the perimeter (in meters).

Answer:

Step-by-step explanation:

I think it is a strangely worded question as they only refer to the larger gear turning.

I believe that this is what they are going for.

Number of teeth passing in each revolution

The Numbers match when the large gear turns two times as the smaller gear turns three times.

tino4ka555 [31]
All you have to do is 
1) order data from lest to greatest 
2) find 2 middle number
3) add both numbers 
4) put fraction and then put 2 under the bottom 
(example)
                 27,33,38,41,42,52,60,64,68,72
                                 ^   ^                                  42+52=94 divide by 2= 94/2  
                              AVERAGE

On a baseball field, the pitcher’s mound is 60.5 feet from home plate. During practice, a batter hits a ball 195 feet at an angl
worty [1.4K]

In this problem, we can imagine that all the points connect to form a triangle. The three point or vertices are located on the pitcher mount, the home plate and where the outfielder catches the ball. So in this case we are given two sides of the triangle and the angle in between the two sides.

<span>With the following conditions, we can use the cosine law to solve for the unknown 3rd side. The formula is:</span>

c^2 = a^2 + b^2 – 2 a b cos θ

Where,

a = 60.5 ft

b = 195 ft

θ = 32°

Substituting the given values:

c^2 = (60.5)^2 + (195)^2 – 2 (60.5) (195) cos 32

c^2 = 3660.25 + 38025 – 20009.7

c^2 = 21,675.56

c = 147.23 ft

<span>Therefore the outfielder throws the ball at a distance of 147.23 ft towards the home plate.</span>

At a clothing store, Ted bought 4 shirts and 2 ties for a total price of $95. At the same store, Stephen bought 3 shirts and 3 t
zepelin [54]

Answer:

$19.50

Step-by-step explanation:

We can turn these into equations by making the shirts 's' and the ties 't'.  

4s+2t=95 and 3s+3t=84

Now we can solve the system of equations with substitution.

Prove that x=2 if 4^x=8x...where ^ stands for "to the power of".
Romashka [77]
In order to prove this, you simply plug in the number 2 everywhere you see X:

4^(2) = 8(2). 

Simplify

16 = 16 √

Since this checks out, x is proven to be 2.
