Marcy split her income from last week equally between paying her student loans, rent, and savings. She put $650 in savings. How much did Marcy earn last week?

Answers

Final answer:

Marcy's total weekly income was calculated by multiplying the amount she put in savings ($650) by the number of equal parts (3), resulting in a total of $1950 earned last week.

Explanation:

To find out how much Marcy earned last week, we need to consider that she split her income equally into three parts: paying her student loans, rent, and savings. Given that she put $650 in savings, and each of the three parts is equal, we can calculate her total weekly income by multiplying $650 by 3 (the number of equal parts).

Total weekly income = $650 (amount put in savings) × 3

Total weekly income = $1950

Therefore, Marcy earned a total of $1950 last week.

Six months after a divorce, the former wife and husband each take a test that measures divorce adjustment. The wife’s score is 63, and the husband’s score is 59. Overall, the mean score for divorced women on this test is 60 (SD = 6); the mean score for divorced men is 55 (SD = 4). Which of the two has adjusted better to the divorce in relation to other divorced people of their own gender? Explain your answer to a person who has never had a course in statistics

Answers

Note that
(63 – 60)/6 = 1/2
(59 – 55)/4 = 1
So, in relation to other divorced women, the score of 63 is only 1/2 SD above the average. But in relation to other divorced men, the score of 59 is 1 SD above the average. That means the husband has adjusted better to the divorce in the relation to other divorced people of his gender.

which equation shows y+1/5=3x in standard form?

Answers

I believe the correct answer is 15x + 5y =-1 but im not positive cause i did the problem and got -1 but the equation i got looks different i got the equation -15x + 5y = -1
These are the steps i followed
You always begin by the Given equation, which is in this case:
y+ = 3x
To remove the fraction, you multiply the whole equation by 5:
5y + 1 = 15x
Then, you move the "15x" the left-side of the equation, changing it's sign
-15x + 5y +1 = 0
You move the "1" to the right side, changing it's sign
-15x + 5y = -1

The answer is 15x-5y=1.

Find the sum or difference 1/4(q-12)+1/3(q+9)

Answers

1/4(q-12) + 1/3(q+9), Then you must use the distributive property to get 1/q-3+1/3q+3. Then you simplify by combining like terms to get, 7/12q. You do not have any constants because they cross each other out.

Final answer:

To find the sum of 1/4(q-12)+1/3(q+9), distribute the fractions, combine like terms, and simplify to get the final answer of 7/12q.

Explanation:

The question requires finding the sum of two algebraic expressions involving the variable q. To solve this, we need to combine like terms after distributing the fractions through the parentheses. Here's the process:

Distribute 1/4 through (q-12): 1/4 * q - 1/4 * 12 = 1/4q - 3.

Distribute 1/3 through (q+9): 1/3 * q + 1/3 * 9 = 1/3q + 3.

Add the results together: 1/4q - 3 + 1/3q + 3.

Combine like terms: To add 1/4q and 1/3q you need a common denominator. The common denominator for 4 and 3 is 12, so convert fractions: 3/12q + 4/12q = 7/12q.

Combine constants: -3 + 3 = 0, so they cancel out.

The final answer is 7/12q.

Therefore, the simplified form of 1/4(q-12)+1/3(q+9) is 7/12q.

The number of hours she practices each day is unknown, so let's call it x.

She practices dancing x hours each day she goes to practice.
Since she practices 3 days per week, in a week she practices 3x hours.
In two weeks she practices 2(3x) hours, or 6x hours.

We are told she practices 12 hours in 2 weeks, so 6x must equal 12.

The equation is

6x = 12

We can solve it by dividing both sides by 6.

x = 2

She practices 2 hours per day.

Check:
2 hours per for 3 days = 2 * 3 hours = 6 hours in 1 week.
In 2 weeks, she practices 2 * 6 hours = 12 hours.
Our solution is correct.

When John bought his new computer, he purchased an online computer help service. The help service has a yearly fee of $25.50 and a S10.50 charge for each help session a person uses. If John can only spend S170 for computer help this year, what is the maximum number of help sessions he can use this year?

Answers

The yearly fee can be subtracted, resulting in 170-25.50=144.5

So with 10.50 a session, you must divide, resulting in around 13.8 sessions.

13 sessions if you need a whole number.

Maya's school held an aluminum collection program in which they collected aluminum and brought it to be recycled. In the first week, Maya collected 4/20 lb of aluminum and her friend Abigail collected 7/8 lb. a. which girl collected more aluminum? b. how much aluminum did the two girls collect?

Answers

If you put this into the calculator, 4/20 is .2 and 7/8 is .875 therefore Abigail collected more. If you use them as the same denominator, you have 8/40 for Maya and 35/40. And if you add these two numbers together, you get 1.075 which is 43/40 as a fraction

a)If Maya collected 4/20 lb of aluminum and her friend Abigail collected 7/8 lb Abigail collected more aluminum.

b) 43/40 lb of aluminum the two girls collect.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that, in the first week, Maya collected 4/20 lb of aluminum, and her friend Abigail collected 7/8 lb.

We have to simplify the expression,

Maya collected 0.2 lb of aluminum, and her friend Abigail collected 0.875 lb.

From the given fraction it is obtained as Abigail collected more aluminum.

The amount  of aluminum did the two girls collect is,

=4/20+ 7/8

=43/40

Thus, If Maya collected 4/20 lb of aluminum and her friend Abigail collected 7/8 lb Abigail collected more aluminum and 43/4 lb of aluminum than the two girls collect.

720 pt in a hour converted to quarts in a min

Answers

1 quart = 2 pints

720/2 = 360 quarts per hour

1 hour = 60 minutes

360/60 = 6 quarts per minute

To convert 720 pints per hour to quarts per minute, divide the number of pints (720) by 2 to get quarts per hour (360), then divide by 60 minutes to find quarts per minute, resulting in 6 quarts per minute.

To convert 720 pints (pt) per hour to quarts (qt) per minute, first, we need to understand the relationship between pints and quarts. 1 quart is equal to 2 pints.

Therefore, to convert pints to quarts, we would divide the number of pints by 2. We also need to convert from per hour to per minute. Since there are 60 minutes in an hour, we divide the per-hour quantity by 60 to find the per-minute quantity.

Here's the step-by-step conversion:

Start with 720 pints per hour.

Since 1 quart is equal to 2 pints, divide 720 by 2 to convert to quarts. 720  2 = 360 quarts per hour.

To convert quarts per hour to quarts per minute, divide by 60 (since there are 60 minutes in an hour). 360   60 = 6 quarts per minute.

Therefore, 720 pints in an hour is equivalent to 6 quarts per minute.
