How to subtract 32/10 and 7/5
Answer:
18/10 or 1 4/5
Step-by-step explanation:
32/10 - 7/5
Remember that in order to subtract fractions, you always need to have the same denominator.
The denominator of 32/10 is 10.
The denominator of 7/5 is 5.
Are the denominator the same? In other words, are 10 and 5 equal? No, so now we need to make the denominator the same so that they are equal. To do that, find the LCM of 10 and 5.
List the LCM:
10: 10, 20, 30
5: 5, 10, 15, 20
Do you see any numbers in the list of the two numbers that are the same? Yes, 10 and 20. But since we are finding the LCM (Least common multiple), we need to use the smallest common multiple, which is 10.
Now that we found the LCM, make the denominator of 7/5 the same as 32/10.
To do that, just multiply the numerator and the denominator of 7/5 by 2; 7 times 2 is 14, 5 times 2 is 10. The final fraction should be 14/10.
Do 14/10 and 32/10 have the same denominator now? Yes, right?
Now, it’s the simple part. We now have the expression, 32/10 - 14/10.
Just subtract across, but keep the 10 as the denominato. 32 - 14 is 18. Keep the denominator 10, and you get 18/10 as your answer.
Therefore, 18/10 or 1 4/5 (if turned into a mixed fraction and simplified) is the answer. Hope this helps!

Find the slope of the line graphed below.
The cost of admission to the Flemington Aquarium is $11.50 for each senior citizen, $14.75 for each adult, and $7.25 for each child. A family of 2 adults and 1 child plans to spend the day at the Flemington Aquarium. What if 2 more tickets for admission are purchased? If the additional tickets cost $14.50, determine what type of tickets the family purchases. Explain how you can determine the answer without calculating.
Answer:
Step-by-step explanation:
A) $51.5
B) two children tickets
Step-by-step explanation:
Given that the cost of admission for the Flemington Aquarium is $11.50 for each senior citizen, $14.75 for each adult and $7.25 for each child.
The cost of admission for the family of 3 adults and 1 child will be
(3 × 14.75) + (1 × 7.25)
44.25 + 7.25 = 51.5 dollars
What if two more tickets for admission are purchased for a total of $14.50?
Since there is no ticket of that amount, we can determine what type of tickets the family purchases by taking the amount of child tickets away from the amount. That is
14.5 - 7.25 = 7.25
The remaining money amount to child ticket again. We can therefore conclude that the two more tickets for admission purchased for a total of $14.50 are for 2 children tickets

Simone cut out a 72 cm parallelogram. The height is 12 cm. Find the length of the base
Answer:
The base is 24 cm
Step-by-step explanation:
There are three ways to look at this problem:
12 + 12 + 24 + 24 = 72
or
2(12+b) = 72
b = 24
or
24 · 12 = 72

im cold n tired just gimme the answer dont play with me:/
Answer:
A) y = 3x + 2 y = -2x + 5
Step-by-step explanation:
We can rule out options B and D right away, because one of the lines' y-intercept is positive 2 not negative.
(Remember that y-intercept is the b in y=mx+b).
So at this point we know the answer is either A or C.
We can also rule out C though, because the second line's y-intercept is positive 5, while the second line in option C is negative.
You can also use the slope of each line to double check.

cherries is $7.25 per pound and she has a coupon for $4.75 off the final
amount. With the coupon, how much would Zoey have to pay to buy 5
pounds of cherries? Also, write an expression for the cost to buy p
pounds of cherries, assuming at least one pound is purchased.
Answer:
She pays $31.50
7.25 x p OR (7.25 x p) - 4.75 if coupon included
Step-by-step explanation:
7.25 x 5 = 36.25

Edward deposited $6,000 into a savings account 4 years ago. The simple interest rate is 3%. How much money did Edward earn in interest?
Answer:
Edward earned $720 in interest.
Step-by-step explanation:
3% of 6000 is 180
0.03*6000 is 180
180*4=720
$720
Answer: interest = 720
Step-by-step explanation:
3/100 x 6,000/1 = 180/1 = 180
since it's 4 years
180 x 4 = 720
Percentage is roughly always out of a 100

A band expects to put 12 songs on their next CD. The band writes and records 2% more songs than they expect to put on the CD. During the editing process, 40% of the songs are removed. How many songs will there be on the final CD?
Step-by-step explanation:
they expect originally to put 12 songs on the CD.
are you sure about the 2% ? is that not 20% ? or better 25%.
because
100% = 12
1% = 100%/100 = 12/100 = 0.12
2% = 1%×2 = 0.12×2 = 0.24
"0.24 songs more" does not really make any sense.
20% would then be 2.4 songs, which would mean 2 songs, but 2 would be only 2/0.12=16.7%.
but 25% would be 0.12×25 = 3. so, 3 songs more.
and that makes sense.
so, they produced 25% or 3 songs more than they expected to put on the CD. that is 12+3=15 songs.
now, we have a new 100% :
100% = 15
1% = 15/100 = 0.15
40% = 0.15×40 = 6
so, 6 songs are removed.
that leaves 9 songs on the CD.
Contestants on a game show spin a wheel with 242424 equally-sized segments. Most of those segments show different prize amounts, but 222 of them are labeled "bankrupt":Suppose that a contestant is going to spin the wheel twice in a row, and the outcome of one spin doesn't affect the outcome of future spins. What is the probability that NEITHER of the spins land on "bankrupt"?
Using the principle of probability, the probability that the outcome of both spins does not land on "bankrupt" is 1/144
Given the Parameters :
Total Number of possible outcomes = 24 Number of outcomes labeled bankrupt = 2 Labels which aren't labeled bankrupt = 24 - 2 = 22Recall :
P(A) = required outcome / Total possible outcomesFirst spin :
P(not bankrupt) = 2 / 24 = 1/12Second spin :
P(not bankrupt) = 2/24 = 1/12P(neither lands on bankrupt) = 1/12 × 1/12 = 1/144
Therefore, the probability that neither lands on bankrupt is 1/144

A chemist is doing a new experiment to see if a new
medicine will kill the Corona virus. He starts the test with
10,000,000 virus cells, and after 12 hours there are 5,
000,000 virus cells. How many cells should he expect to be
left after one week? Create an equation.
Answer:
610 virus cells
Step-by-step explanation:
let 10,000,000 be y And 12hrs be z and the cells left at the end of the week be x
I.e
[tex]x = y { \binom {1} {2}} ^{ \binom{t}{tx} } [/tex]
where tx is how long it takes for 1/2 of it to decay and t is the number of hours it's supposed to decay
So
[tex]x \: = \: 10000000 \: \times {{\frac{1}{2}}} ^{ \frac{24 \times 7}{12} } [/tex]
t is 7 weeks × 24 to convert to hours
so, therefore, 24 × 7 ÷ 12 is 14 [tex]x = 10000000 \times \frac{1}{ {2}^{14} } [/tex]
so 10,000,000 ÷ 2^14
10,000,000 ÷ 16,348 = 610.4
therefore there are approximately 610 viruses left after one week
