slavikrds [6]3 years ago
4 0

Answer:

  • x = 19, TS = 22

Step-by-step explanation:

  • Use ratios to solve for x. Corresponding sides have same ratio.

Q1

  • (x + 5)/30 = (36 - 20)/20
  • (x + 5)/30 = 16/20 = 4/5
  • 5(x + 5) = 4(30)
  • 5x + 25 = 120
  • 5x = 95
  • x = 19

Q2

  • (5x - 2)/(3x + 1) = 39/26
  • (5x - 2)/(3x + 1) = 3/2
  • 2(5x - 2) = 3(3x + 1)
  • 10x - 4 = 9x + 3
  • 10x - 9x = 3 + 4
  • x = 7

TS = 3x + 1 = 3(7) + 1 = 22

athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be given to the second-place finish
Agata [3.3K]

Using the permutation formula, there are 157,410 ways for the medals to be distributed.

<h3>What is the permutation formula?</h3>

The number of possible permutations of x elements from a set of n elements is given by:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this problem, 3 athletes are chosen from a set of 55, hence the number of ways is given by:

P(55,3) = 55!/52! = 157,410

157,410 ways for the medals to be distributed.

The engine of a car has a displacement of 305 cubic inches. what is the displacement in cubic feet? round your answer to 2 decim
ipn [44]
 solution
 1 inch = 2.54 centimeters
Therefore, to convert to cubic measurements
 (1 in)³ = (2.54 cm)³
 Thus;
1 in³ = 16.387 cm³
Hence 305 cubic inches will be equivalent to
  305 × 16.387
 = 4998.035 cm³

The number 900 has an interesting property in that the only primes that divide into it evenly are 2, 3, and 5. What are the next
Tasya [4]

900 = 2 · 2 · 3 · 3 · 5 · 5

Next numbers:

2 · 2 · 2 · 3 · 3 · 3 · 5 · 5 · 5 = 900 · 15 = 13,500

2 · 2 · 2 · 2 · 3 · 3 · 3 · 3 · 5 · 5 · 5 · 5 = 13,500 · 15 = 202,500

202,500 · 15 = 3,037,500

3,037,500 · 15 = 45,562,500

Which function, when graphed, would contain all the points in the table below? x 0,-1,-4 y 0,1,2
galina1969 [7]
Let's take a look at the <em>relationship</em> between x and y in this function. When we look at the first non-zero pair, (-1, 1), we can see that, in the transition from x to y, our x value was had to have been multiplied by -1. For now, we could tentatively say that y = -x. Unfortunately, the next pair, (-4, 2), debunks this hypothesis pretty quickly, as 2 ≠ -(-4). We'll need to reexamine the relationship between x and y here.

One patter that we can be fairly confident in is that multiplication by -1; the sign is flipped from negative to positive when we go from x to y in each case, so we can hold onto that component of the function. Something else is happening before that sign flip, though, and we'll need to look into that by seeing how else the numbers are connected.

Ignoring the negative signs for a moment, let's take a look at the pairs (1,1) and (4, 2). We can transform 1 to 1 pretty easily; we simply multiply or divide it by 1. From 4 to 2, we can either divide it by 2 or multiply it by 1/2. Let's thing in terms of division for now. We know that

1/1 = 1 (obviously)
4/2 = 2

We might have something here! It looks like the number we divide by and the number we obtain are the same, so let's explore this further. Multiplying both sides by those denominators, we find:

1 = 1²
4 = 2²

Almost there! To finally find the relationship, we just square root both sides to get:

√1 = 1
√4 = 2

So that was the function we'd been looking for - a square root! Putting that together with what we said about changing the sign at the beginning, we have:

y =√(-x)

To verify this, we just need to plug in a few pairs, and we find that indeed:

1 = √-(-1) = √1 = 1
2 = √-(-4) = √4 = 2
