The ratio of men to women working for a company is 7 to 5. If there are 336 employees total, how many women work for the company?
please answer soon as possiblee!!!
Answers
==========================================================
Explanation:
m = number of men
w = number of women
The ratio of men to women is 7 to 5, meaning that m/w = 7/5
Cross multiply to get 5m = 7w.
Then divide both sides by 5 to end up with m = 7w/5 which is the same as m = 1.4w
We'll use this equation later.
------------------
Since there are 336 total workers, we know that:
m+w = 336
1.4w+w = 336 .... replace m with 1.4w
2.4w = 336
w = 336/(2.4)
w = 140 women work at the company
and m = 1.4*w = 1.4*140 = 196 men work at the company as well.
------------------
Checking the answer:
m+w = 196+140 = 336
m/w = 196/140 = (7*28)/(5*28) = 7/5
This helps confirm we have the correct value of w.

Answer:
wouldnt the answer be 9.9
Step-by-step explanation:
12.1-2.2=9.9
Answer:
Step-by-step explanation:
The elevation of Tammy's house is 3 1/2 times the elevation of Winston’s house which is 12.1 and that would give us 42.35 and then subtract the 2pm ocean elevation which is 2.2 and that would leave us with the answer of 42.15. so no the answer is not 9.9

Answer:
7.5
Step-by-step explanation:
To find the area of a trapezoid it is:
[tex]A= \frac{a+b}{2}h[/tex]
Where h is the height, b is the base, and a is the "top base," so our values are:
h = 5
b = 9
a = 6
Plug them in and solve:
[tex]A= \frac{a+b}{2}h[/tex]
[tex]A= \frac{6+9}{2}5[/tex]
[tex]A= \frac{15}{2}5[/tex]
[tex]A = (7.5)(5)[/tex]
[tex]A = 37.5[/tex]
The area of the rectangle is found by using:
[tex]A=bh[/tex] where b is the base and h is the height. So our values are:
b = 6
h = 5
Plug in and solve:
[tex]A=bh[/tex]
[tex]A=(6)(5)[/tex]
[tex]A = 30[/tex]
Subtract the rectangle from the trapezoid:
37.5 - 30 = 7.5
Answer: 7.5

Step-by-step explanation:
2x -4y = 10 lets find y
-4y = 10+2x
-4y = 2x-10
-4y/-4 = 2x/-4 - 10/-4
y = - 0.5x + 2.5

how to approach answering questions for hw and for exam
step 1 hw find a diagram exam rewrite the diagram
step 2 hw work out each multiple question
step 3 see below how workings should be
SIGMA TELLS US The nth term is = k
SIGMA TELLS US The bottom value is value we start with _vs
SIGMA TELLS US The top value is the term we end with - te
A n-2 turns into 9 which makes 7n-5 become -2+7-5 = 0
B n-12 turns into 12 which makes 7n-5 become -1 +7- 5 = 1 (12 x7=84 and -5+84 = 79)
we can prove by using nth common term 7 x 12 -5 = 79
C n -1 turns into 5 which becomes -1+7 = 6
D n- 1 turns into 5 which becomes -1+7-5 = 1
we see the sequence given is 2, 9, 16 ....79 it is ascending sequence +7
we know the nth term is 7n-5 as we work out first step ( 2 - 7= -5)
we see the term we end with is either 9 12 or 5 and we see the end term given value is 72 so B is our answer.
Sheila walks 3 miles in 9/10 of an hour. How fast does she walk per hour?
Answers
Answer:
1 hours = 60 min
60 x 9/10 = 54 min
3 divided by 54 = 1/18
so she walks 1/18 miles per hour.
Im not sure though. It might be 3 divided by 9/10 = 3 1/3. I’m not that confident in my answer. But it is definitely one of them, either 1/18 or 3 1/3.

A company offers you a salary of $2,000 per month plus a signing bonus of $10,000. What is the yearly salary rate? PLEASE HELP!!!!
Answers
Since yearly, without the bonus, you would make a certain amount by multiplying $2,000 to a year, which is 12 months.
2000 × 12 = 24,000 a year.
That would be $24,000 a year.
Next, we can add 10,000 to the amount, since you are not getting paid that much for a year. It is just a "...plus...", a bonus.
24,000 + 10,000 = 34000
Therefore, the yearly salary rate will be $34,000 a year.

Answers
Answer:
Music and dance. It's easier in today's society to see black influence over popular music genres, however, this most likely stemmed from African culture, and as you said, in colonial North America. The colonials who enslaved the Africans most likely (i keep using this term so that you can confirm with your own teachings) were influenced by their customs and music (which can include dance) and attempted to integrate it into their own culture. This would trickle down into the future generations through black-dominated genres, such as hip-hop, rap, drill, and dances, such as break dancing, hip-hop (dancing), and the sort.
What is the contrapositive of "If our plane is not late, then we make our connecting flight.
Answers
Answer:
If we make our connecting flight then our plane is not late.
Step-by-step explanation:
The contrapositive occurs when the conclusion and the hypothesis change places. Let the hypothesis be represented by "p" and the conclusion be represented by "q".
hypothesis (p) [ conclusion (q)]
Now in the given statement: If (our plane is not late), then [we make our connecting flight].
statement If p then q
contrapositive If q then p
The required contrapositive statement is: "If we do not make our connecting flight, then our plane is late."
The contrapositive of the statement "If our plane is not late, then we make our connecting flight" is formed by negating the hypothesis (antecedent) and the conclusion (consequent) and then switching their positions. The contrapositive is logically equivalent to the original statement. Here's the contrapositive:
Original Statement: If our plane is not late, then we make our connecting flight.
Contrapositive: If we do not make our connecting flight, then our plane is late.
In the contrapositive, we negate the "our plane is not late" to "our plane is late" and negate "we make our connecting flight" to "we do not make our connecting flight." Then we switch their positions.
