A shoe making company makes 256 pairs of boots in a day how many pairs of boots do they make in 260 days​
My name is Ann [436]

Answer:

66560 pairs

Step-by-step explanation:

let the number of pairs of boots the company makes in 260 days = X

1day -----------------256pairs

260days-------------X

cross multiplying

1×X = 260×256

X= 66560

therefore, in 260days, he makes 66560 pairs

PLEASE HELP!!This is joshs solution for the equation x^2-6x-7=0: x^2-6x-7=0
iren [92.7K]

Answer:

  no. see below

Step-by-step explanation:

This much of Josh's working is correct:

  x^2-6x=7

  x^2-6x+9=7+9

  (x-3)^2=16

At this point Josh apparently overlooked the fact that he needed to take the square root of both sides of the equation. Had he done that, he would have ...

  x -3 = ±4

  x = 3+4 . . . or . . . 3 -4

  x = 7 or -1

_____

Josh reported values of x that would match ...

  x -3 = ±16

He <em>violated the equal sign</em> by taking the square root on the left, and multiplying by ±1 on the right. Doing different operations on the two sides of the equation will mean the value of x is changed to something other than what you're looking for.

There are 6 pennies, 9 nickels, and 3 dimes in a box. Find the probability of P(1 nickel and then 1 dime)—with replacement. what
densk [106]

<u>The probability is </u><u>1/12</u>

The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there is replacement, we still have 18 total coins to choose). With these, we get: (1/2) * (3/18) = 3/36 = 1/12
