Answer:
Wanda brought 9 carrot sticks.
Step-by-step explanation:
- Convert 30% to a decimal by removing the percent sign and dividing by 100: 30 ÷ 100 = 0.30
- Substitute 0.30 for 30% in the equation: 30% x 30 = Y becomes 0.30 * 30 = Y
- Do the math: 0.30 x 30 = 9
- Y = 9
- So 30% of 30 is 9
- Double check your answer with the original question: How many carrot sticks did Wanda bring? Multiply 0.30 x 30 = 9
7 out of 24 is made by other companies because you need to find a common denominator for all of the numbers which is 24. 1/3 times 8 is 8/24, 1/4 times 6 is 6/24 and 1/8 times 3 is 3/24. Then add all of those fractions and you get 17 then subtract 24 by 17 to get 7 out of 24 as your fraction. Hope this helps!
A line is a collection of points.
1). Multiply (5400 inches) by (1 foot / 12 inch) then by (1 mile / 5280 foot).
(See explanation at the bottom)
= (5400 inch) x (1 foot / 12 inch) x (1 mile / 5280 foot)
= (5400 x 1 x 1 / 12 x 5280) (inch - foot - mile / inch - foot)
= 0.0852 mile
2). Multiply (16 week) by (7 day/week) then by (24 hour/day)
then by (60 minute/hour) then by (60 sec/minute).
3). Multiply (54 yards) by (3 foot/yard) then by (1 meter/3.28 foot)
and then by (1000 mm/meter)
4). Multiply (36 cm/second) by (3600 second/hour) then by (1 meter/100 cm)
then by (1 mile/1609.3 meter).
5). Look up how many grams in a pound ('P')
Look up how many mL in a gallon ('G')
Multiply (1.09 g/mL) by ( 1 pound/ P gram) then by (1 gallon/ G mL)
6). Multiply (32 foot/sec) by (1 meter / 3.28 foot) then by (60 sec/minute).
Each time I told you to multiply by something, it was always a fraction
where the numerator and denominator are equal, like (60 seconds/minute)
or (1 foot / 12 inch). Since the top and bottom of the fraction are equal, the
value of the fraction is ' 1 ' , and multiplying by it doesn't change the value,
it only changes the units ... that's what this whole exercise is about.
When you multiply, KEEP the units in the product, and then, after you multiply, you can 'cancel' units out of the top and bottom of the product.
Like if you have 'feet' on top and bottom, just cross them out. When you're done, if you did it correctly, the last unit you end up with will be the one you want.
Answer:
D) 7/8
Step-by-step explanation:
The probability that there is at least one student at both Saturday's and Sunday's events is the inverse of the probability of having all students selecting either Saturday OR Sunday.
Since the probability of a student selecting Saturday is 0.5, the probability of all 4 students selecting that day is
0.5 * 0.5 * 0.5 * 0.5 = 1/16
Then the probability of having all students selecting either Saturday OR Sunday is twice that, which is 2/16, or 1/8
Therefore the probability that there is at least one student at both Saturday's and Sunday's events is 1 - 1/8 = 8/8 - 1/8 = 7/8
