at a party there were four large submarine sandwiches, all the same size during the party, 2/3 of the chicken sandwich, 3/4 of the tuna sandwich, 7/12 of the roast beef sandwich and 5/6 of the veggie sandwich were eaten. which sandwich had the least amount left ?

Answers

Answer 1

Answer:

Answer: The answer is the Veggie Sandwich

Step-by-step explanation: Given that there are four large submarine Sandwiches in a party and all of them are of the same size.

Some parts of each of them were eaten during the party. We are to find the Sandwich that has the least amount left.

The fractions of the Chicken Sandwich(C), Tuna Sandwich(T), Roast beef Sandwich(R) and the Veggie Sandwich(V) that were eaten during the party are given by

$C=(2)/(3),\n\nT=(3)/(4),\n\nR=(7)/(12),\n\nV=(5)/(6).$

Therefore, the fractions of the Sandwiches that left will be

$C'=1-C=1-(2)/(3)=(1)/(3)=(4)/(12),\n\nT'=1-T=1-(3)/(4)=(1)/(4)=(3)/(12),\n\nR'=1-R=1-(7)/(12)=(5)/(12),\n\nV'=1-V=1-(5)/(6)=(1)/(6)=(2)/(12).$

Out of the four fractions, V' is the smallest, so the Veggie Sandwich has the least amount left.

Answer 2

Answer: Veggi sandwich had the least amount left

80% of how many games is 32 games?

Answers

percent means parts out of 100 so
80%=80/100=8/10=0.8
'of' can be translated to as multiply
0.8 times x games is 32 games
0.8 times x=32
note:0.8x= 0.8 times x
0.8x=32
multiply both sides by 10
8x=320
divide both sides by 8
x=40
the number is 40

So, you can set it up like: is over of = % over 100
We need a proportion to solve that answer.
So put the "is" part, which is 32 on top on the left over the "of" part, which is what you do not know, so put x as a variable. Now put 80% since it's the percentage over 100 on the right side. Now, it should look like this: 32/x=80/100(you do not need to include the % sign). Now cross multiply and you get: 80x=3200. Now divide 80 on both sides and you get 40. So there would be 40 games.
Hope this helps. :-)
PS I'm sure glad I learned about proportions to help. (I hope I did)

Figure A is a scale image of figure b. What is the value of X?

Answers

Answer:

x = 4.4

Step-by-step explanation:

To determine the scale factor, calculate the ratio of corresponding sides, image to original, that is

$(x)/(11)$ = $(4)/(10)$ ( cross- multiply )

10x = 44 ( divide both sides by 10 )

x = 4.4

Jordan drove for 6 hours at 55 miles per hour, while Matt drove for 3 hours at 60 miles per hour. If Isaac drove 82 miles longer than Jordan and Matt drove combined, for how many miles did Isaac drive?--------- miles

(Hint: Rate × Time = Distance)

Answers

If you look at the equation, we have to multiply the hour and the mph(miles per hour) together to find how many miles they drove. For Jordan, we would have to multiply 6 times 55 which is 330. Jordan drove 330 miles. For Matt, we have to multiply 3 times 60, which gets us 180. Together, they would have drove 510 miles. If Isaac drove 82 miles longer than Jordan and Matt drove combined, we would get 582 miles. Isaac drove 592 miles.

PLEASE HELPA group of students were surveyed to find out if they like bike riding and/or roller skating as a hobby. The results of the survey are shown below:
80 students like bike riding
20 students like bike riding but do not like skating
90 students like skating
40 students do not like bike riding
Make a two-way table to represent the data and use the table to answer the following questions.
Part A: What percentage of the total students surveyed like both bike riding and skating? Show your work.
Part B: What is the probability that a student who does not like bike riding also does not like skating?

Answers

I don't know how to do the graph.

Part A: 80+20+90+40= 230 students. 90 for skating + 80 for biking= 170 170/230= 0.74 =74%

Part B: 20 for no skating+ 40 for not biking = 60. The probability is 60 out of 230 students
