Michael is buying new shirts and pants for school. He bought shirts for $38 each and pants for $38 each. He purchased nine items and spent a total of $222. How many shirts did he buy?
Answer:
No possible solution
Step-by-step explanation:
Let:
Shirt = x
Pant = y
x + y = 9 - - - - - - - - - (1)
38x + 38y = 222 - - - (2)
From (1):
y = 9 - x
Put y = 9 - x in (2)
38x + 38(9 - x) = 222
38x + 342 - 38x = 222
Based on the Given parameters, we can conclude that the equation does not have a possible solution.

Which expression is equivalent to 1/144
Answer: 1 12/12
Step-by-step explanation:
Answer:
[tex]\displaystyle \frac{12^5}{12^7}[/tex]
Step-by-step explanation:
Equivalent Fractions
We need to recall the following properties of exponentials:
[tex]\displaystyle \frac{x^a}{x^b}=x^{a-b}=\frac{1}{x^{b-a}}[/tex]
Additionally, we have that 144=[tex]12^2[/tex], thus the given expression
[tex]\displaystyle \frac{1}{144}=\frac{1}{12^2}[/tex]
From the options presented, we have to find which one gives 12 squared in the denominator. It's apparent that the first choice:
[tex]\displaystyle \frac{12^5}{12^7}=\frac{1}{12^{7-5}}=\frac{1}{12^2}[/tex]
Is the correct choice.
Answer:
[tex]\mathbf{\displaystyle \frac{12^5}{12^7}}[/tex]
how do you get -11.9 from -6.7+(-5.2)
and explain in words how
If you just type that exact equation into a calculator it gives you the same answer as well
Answer:
You get -11.9 from -6.7+(-5.2) because you are adding 2 negative numbers. Just forget the negative signs are there when your adding negatives. 6.7 + 5.2 = 11.9 and then just add the negative in front and that's how you get your answer -11.9
Hope this helped!
Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\, percent of the sampled orders would have been returned
If Beatriz takes a simple random sample of 350 orders from the more than 5000 total to her store and finds. The probability that more than 12 percent of the sampled orders would have been returned is 0.02.
How to find the probability?Mean = n * p
Mean = 350 * 0.09
Mean= 31.5
Standard deviation = √ p * (1 - p)/n
Standard deviation = √ 0.09 * 0.91/350
Standard deviation = 0.01529
Using the normal distribution table
p>0.12
P(p>0.12) =0.02
Therefore the probability that more than 12 percent of the sampled orders would have been returned is 0.02.

Carol is mixing pink paint. The ratio of red to white paint is 2:1. If carol uses 6 parts red paint. How much white paint does she need?
Answer:
3 parts
Step-by-step explanation:
This is just ratios. We know that red paint:white paint is equal to 2:1. Therefore we just have to substitute the values in.
Red paint = 6, so
6: White paint (=1)
Meaning that all we have to do is divide 6 by 2 (to find the value of one part), giving us 3 parts.
