If y varies directly as x, find the constant of variation if y = 25 and x = 5.
Soloha48 [4]

Answer:

The constant of variation is 5

Step-by-step explanation:

We know direct variation is of the form

y = kx

We know y =25 and x=5

25 = k*5

Divide each side by 5

25/5 = 5k/5

5 = k

Find the value of x.<br> Right triangle: Hypotenuse is 11, base is x, angle is 22 degrees.
kirill [66]
We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:
cos(22) =  \frac{x}{11}

We need to solve for x, so let's isolate it:
x = 11cos(22) = 10.2

So, x = 10.2 units

1. When Lucas dumped the coins out of his piggy bank, he noticed that there were only nickels and dimes, and the number of nicke
vaieri [72.5K]

1- The total value of the Lucas coins dumped out of his piggy bank was $ 5.

2- Franco dumped out 36 coins from his piggy bank (16 quarters and 20 nickels).

3- There is no possible solution, as neither combination gives a total of $ 10, which is the combined total of Lucas and Franco's coins.

1- Given that when Lucas dumped the coins out of his piggy bank, he noticed that there were only nickels and dimes, and the number of nickels was twice the number of dimes, to determine, if there were 50 nickels, what was the total value of the Lucas coins dumped out of his piggy bank, the following calculation must be performed:

  • Nickel = 0.05
  • Dime = 0.10  
  • N + D = X
  • N + 1 / 2N = X
  • 50 + 25 = 75  
  • 50 x 0.05 + 25 x 0.1 = X
  • 2.50 + 2.50 = X
  • 5 = X

Therefore, the total value of the Lucas coins dumped out of his piggy bank was $ 5.

2- Since when Franco dumped the coins out of his piggy bank, he noticed that there were only nickels and quarters, and the number of quarters was six more than half the number of nickels, to determine, if the total value of the coins Franco and Lucas dumped out of each piggy bank was the same, how many coins did Franco dump out of his piggy bank, the following calculation must be performed:

  • Nickel = 0.05
  • Quarter = 0.25
  • Q = 2N + 6
  • 4 x 0.25 + 6 x 0.25 = 1 + 1.5 = 2.5
  • 8 x 0.05 = 0.40
  • 2.5 + 0.4 = 2.9
  • 8 x 0.25 + 6 x 0.25 = 2 + 1.5 = 3.5
  • 16 x 0.05 = 0.8
  • 3.5 + 0.8 = 4.3
  • 10 x 0.25 + 6 x 0.25 = 2.5 + 1.5 = 4
  • 20 x 0.05 = 1
  • 4 + 1 = 5
  • 10 + 6 + 20 = 36

Therefore, Franco dumped out 36 coins from his piggy bank (16 quarters and 20 nickels).

3- Since when Callie dumped the coins out of her piggy bank, she noticed that there were only nickels, dimes and quarters, and the number of dimes was one more than twice the number of quarters, and there were half as many quarters as nickels, y the coins dumped out of Callie's piggy bank had a total value equal to that of the coins dumped out of Franco's and Lucas' piggy banks combined, to determine what was the total value of the nickels and dimes dumped out of Callie's piggy bank, the following calculation should be performed:

  • Nickel = 0.05
  • Dime = 0.10
  • Quarter = 0.25
  • (D + 1) + 1 / 2Q + N = 10
  • 1 x 0.1 + 20 x 0.1 + 10 x 0.25 + 20 x 0.05 = 2.1 + 2.5 + 1 = 5.6
  • 1 x 0.1 + 36 x 0.1 + 18 x 0.25 + 36 x 0.05 = 3.6 + 4.5 + 1.8 = 9.9
  • 1 x 0.1 + 38 x 0.1 + 19 x 0.25 + 38 x 0.05 = 3.9 + 4.75 + 1.9 = 10.55

Therefore, there is no possible solution, as neither combination gives a total of $ 10, which is the combined total of Lucas and Franco's coins.

ruslelena [56]

Answer: You would have to send 300 text messages

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30

3. Divide both sides by 0.10 to get x = 300
