<span>the proccess of choosing is independent so probability of choosing from machin1 is:300/1000 =0.3
choosing from machin2 is:707/1010=0.7
the total result is 0.3*0.7=0.21 ;</span>

A dairy needs 336 gallons of milk containing 6% butterfat. How many gallons each of milk containing 7% butterfat and milk contai
Arte-miy333 [17]

We need 84 gallons of 3% butterfat milk and (84 * 3) = 252 gallons of 7% butterfat milk to obtain 336 gallons of 6% butterfat milk.  

<h3>How to work with percentages?</h3>

Let x = number of gallons of 3% milk

Thus;

336 - x = number of gallons of 7% milk

Therefore;

0.03x + 0.07(336 - x) = 0.06(336)

0.03x + 23.52 - 0.07x = 20.16

-0.04x = -3.36

x = 84 gallons

We need 84 gallons of 3% butterfat milk and (84 * 3) = 252 gallons of 7% butterfat milk to obtain 336 gallons of 6% butterfat milk.

What is ​ BC ​ ?<br><br><br> Enter your answer in the box.<br><br> BC=<br> units
kumpel [21]

<u>Answer:</u>

  • The length of BC is 25 units.

<u>Step-by-step explanation:</u>

<u>We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.</u>

  • => 4x + 1 = 2x + 23
  • => 4x - 2x = -1 + 23
  • => 2x = 22
  • => <u>x = 11</u>

<u>Now, let's substitute the value into the expression.</u>

  • => 3x - 8
  • => 3(11) - 8
  • => 33 - 8
  • => <u>25</u>

<u>Hence,</u><u> the length of BC is 25 units.</u>

Hoped this helped.

If I put a different sticker on the 30th, 50th, and 60th pages will any of the first 600 pages have all 3 stickers?
icang [17]

Answer:

so the which page that will have the 3 sticker, we must solve the least common multiple of 30, 50, 60. A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....

The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.

so the least common multiple of 30, 50 and 60 is 300. so the page that will have 3 stickers is 300th page
