Answer:
a/b= 2/15
Explanation:
3a +b
----------- = 7/5
b
now cross multiple both side5(3a+b)=7 x b
15a +5b = 7b
15a = 7b-5b
15a = 2b
15a/2b = 1
a/b x 15/2 =1
multiple both side by 2/15we get,
a/b = 2/15
hope you have no doubt now !
we get ,
If 3a+b/b=7/5. The value of a/b is 2/15.
What is algebra?The area of mathematics known as algebra deals with manipulating or performing operations on abstract symbols rather than numbers.
Algebra is a common thread that runs through practically all mathematics. It involves the study of variables and the rules for manipulating them in formulas.
Since all mathematical applications involve manipulating variables as though they were numbers, elementary algebra is a prerequisite.
Given that, 3a + b/b = 7/5
now cross multiple both side
5(3a+b)=7 x b
15a +5b = 7b
15a = 7b-5b
15a = 2b
15a/2b = 1
a/b x 15/2 =1
Multiply both sides by 2/15
we get,
a/b = 2/15
Therefore, the value of a/b is 2/15.

Which statement best describes how chemical equations demonstrate conservation of mass?
A.
The number of reactants is the same as the number of products.
B.
The compounds are the same on each side of the reaction.
C.
The number of atoms of each element is the same on each side of the equation.
D.
The state of matter is the same on each side of the equation.
Answer:
Explanation:
Let's just get the answer and then show why the others are wrong.
The answer is C.
The number of reactants and Products need not be the same
C3H8 + 5O2 ===> 3CO2 + 4H2O
The reactants = 1 + 5 = 6
The products = 3 + 4 = 7
So A is incorrect.
================
B is saying that
C3H8 + 5O2 ===> C3H8 + 5O2
The answer is obviously not B

Answer:
280
Explanation:
For ease of comparison $20/hr < $12/hr+ commission, let's do it by the hour first.
Hourly pay of the food truck is $12, every burger she sells, she gets 10% of the $12 burger, which is $1.2. Therefore all we need to figure out is 1.2x +$12 > $20. Minus both sides by 12, now all we have is down to the bare minimum: 1.2*X = $8
8 divided by 1.2 is 6.66 (infinite), but since she can't sell 0.6 of a burger, we need to round up, which is 7, keep in mind we are still at hourly. Now we know that she has to sell at least 7 burgers every hour she's working for the food truck, it's a 40-hour work week, 7*40 is 280.
Check:
Food truck: $12+ 12*0.1*7 = $20.4/hr $20.4 > $20
Best of luck for your SAT!

It is known that 45 percent of men snore and 25 percent of women snore. If you put a man and a woman together , what is the probability that someone will be snoring
Answer:
0.35
Explanation:
( 0.45*1 + 0.25*1 ) / 2 = 0.35
The probability that someone would be snoring given the percentage of men and women who snore would be 0.5875.
How to find the probability ?In general, for two independent events A and B, the probability that either A or B occurs is given by:
P(A or B) = P(A) + P(B) - P(A and B)
In this case, we'll need to assume that the man's snoring is independent of the woman's snoring, which seems reasonable in this context.
P(M and W) is the probability that both the man and the woman snore, and since the events are independent, it's given by:
P(M and W) = P(M) * P(W) = 0.45 * 0.25 = 0.1125
Substituting these values into the formula, we get:
P(M or W) = P(M) + P(W) - P(M and W)
P(M or W) = 0.45 + 0.25 - 0.1125
= 0.5875

each day grace eats 40 % of the gummy bears left in a bag at that time .at the end of the second day 27 gummy bears remain how many gummy bears were in the bag at the first day
Answer:
75
Explanation:
Grace has been eating gummy bears for two days.
Let n = number of gummy bears at beginning of first day. Then
0.40n = number of gummy bears eaten on first day, and
0.60n = number of gummy bears remaining at end of first day
0.60n = number of gummy bears at beginning of second day.
0.40 × 0.60n = 0.24n = number of gummy bears eaten on second day
0.60n - 0.24n = 0.36n = number of gummy bears remaining at end of second day
0.36n = 27
n = 27/0.36 = 75
There were 75 gummy bears in the bag at the beginning of the first day.
