The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?

Answers

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

What is the answer to this question? 12/5t=6
First, the equation is (12/5)*t = 6, right?

If it is….

t = 30/12 or 15/6 (simplified)

Steps…

((12/5)*t) * 5 = 6 * 5 -> multiplied both sides by 5 to get rid of denominator
12t = 30
12t/12 = 30/12 -> divided both sides by 12 to single out the t
t = 30/12 or 15/6

The answer is 98 degrees for y

Answer:

Step-by-step explanation:

First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180

For the triangle on the left, sum up the angles and set it to 180 degrees.

60 + 38 + x = 180

x = 82 degrees

Now solve for y by doing this

82 + y = 180

y = 98 degrees

While I'm here, Ill solve for z because it will most likely ask in the next question.

26 + 98 + z = 180

z = 56 degrees

An amusement park sells tickets for families of 4 people for $198. What is the constant of porportionality that relates to the cost of the amusememt park tickets, y, to the number of amusement park tickets sold, x?

Answers

I may or not be correct, but how I solved it is Constant of proportionality equation: y = kx
So if every-time families of 4 cost $198 then $198/4 equals 49.5. y = 49.5x by substituting.

A carnival has a duck-pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 73 ducks floating in the pond. There are 5 ducks marked as large-prize winners, 11 ducks marked as medium-prize winners, and 24 ducks marked as small-prize winners. Find the theoretical probability of winning a medium prize at the duck pond. Express your answer as a decimal. If necessary, round your answer to the nearest thousandth.

Answers

Let's break down this problem step by step.

First, let's understand what's happening here. There's a carnival game where you can pick one duck from a pond. Each duck has a mark under it that might make you a winner of a prize. Some ducks are marked with large prizes, some with medium, some with small, and the rest don't win you any prize.

The total number of ducks in the pond is 73.

Out of these 73 ducks:

- 5 are marked for a large prize,

- 11 are marked for a medium prize,

- 24 are marked for a small prize.

We are asked to find the theoretical probability of picking a duck that has a medium prize mark. The theoretical probability is basically a fraction that compares the number of ways something can happen with the total number of outcomes.

Here, the number of ways you can win a medium prize is equal to the number of ducks that have a medium prize mark, which is 11.

The total number of outcomes is just the total number of ducks you can choose from, which is 73.

The probability (P) of winning a medium prize is then:

P(medium prize) = (Number of medium-prize ducks) / (Total number of ducks)

= 11/73

To convert this fraction to a decimal, simply divide 11 by 73:

= 11 ÷ 73

≈ 0.1507 (rounded to the nearest thousandth)

So, the probability of winning a medium prize at the duck pond is about 0.151 or 15.1%. Imagine, for every 100 ducks you pick (if there were that many), about 15 of them would win you a medium prize.

The theoretical probability of winning a medium prize at the duck pond is ≈ 0.150

To find the theoretical probability of winning a medium prize at the duck pond, we need to determine the ratio of the number of medium-prize-winning ducks to the total number of ducks in the pond.

The total number of ducks in the pond is given as 73.

The number of medium-prize-winning ducks is given as 11.

Therefore, the probability can be calculated as follows:

Probability of winning a medium prize = (Number of medium-prize-winning ducks) / (Total number of ducks)

Probability of winning a medium prize = 11 / 73

To express the answer as a decimal, we divide 11 by 73:

Probability of winning a medium prize ≈ 0.150

Rounded to the nearest thousandth, the theoretical probability of winning a medium prize at the duck pond is approximately 0.150

Which sign makes the statement true?
5.7 x \(10^{2}\) 5,700,000,000,000

Please help me quickly!!

Answers

Answer:

<

Step-by-step explanation:

the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.

The sign that makes the statement true is "=".

If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.

Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

20*5 = 100
