need help asap 20 points. thank u in advance
Answer:
$50 and $6
Step-by-step explanation:
(x-6)(250-5x)=0
250x - [tex]5x^{2}[/tex] - 1500 + 30x = 0
-5x^2 + 280x - 1500 = 0
(divide everything by -5)
x^2 -56x + 300 = 0
(factorise)
(x-50)(x-6)=0
x=50, x=6

1. Bill decided to buy six books on history instead
of four books on politics. It follows, then, that
the opportunity cost of each history book was ______
books on politics.
Answer: 2/3 books on politics
Step-by-step explanation:
The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.
Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.
= Number of politics books / Number of history books
= 4 / 6
= 2/3 books on politics
Bill gave up 2/3 books on politics to get a single history book.

1. The average Third grade student can read 60 words in 5 minutes What is the average reading rate per minute?
Answer:
12 words per minute
Step-by-step explanation:
60/5=12
Help me with this problem
Answer: x=60
Step-by-step explanation:
Hey! X would be 60 because the diagram on the left has proportions of 6/6. The diagram on the right has a porportion of x/60. We want the proportions to be equal so it has to be 60!
6/6 = 1
60/60 = 1 (they are now equal and have equal proportions!)

Mrs. Rodrigues should use Standard deviation.
The correct option is b.
What is a standard deviation?The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.
Given:
Mrs. Rodrigues wants to compare the spread of the test scores of her two biology classes.
From the given choices:
The measures of spread include:
Range, quartiles, interquartile range, variance and standard deviation.
Standard deviation is the appropriate choice.
Therefore, standard deviation is the correct phrase.

To prevent fraying, a binding is attached to the outside of a circular rug whose radius is 3 ft. If the binding costs $1.35 per foot, find the cost of the binding. Use 3.14 for . (Round your answer to the nearest cent.)
$
Answer:
$4.71
Step-by-step explanation:
you would multiply the radius times pi (you would get 6.42 ft) and then divide that by 1.35 (simplifying it to 642 divided by 135 and you would then get 4.706...)which rounds to the answer

Y2-y1/x2-x1
3- (-1)/ -2 -3
4/-5
Answer:
4 over 5 (4/5)
Step-by-step explanation:
Its extremely simple. You need to start from the lower point, and count up until you get to the same lime as the other point. Starting from the lower point, you count up 4 to get on the same line. Then, since its on the right, you count to the right 5, till you get to the dot, and you get 4/5. All you have to do is just count
An average sized person will burn about 350 calories in an hour of walking at a fairly brisk pace. How many calories would you burn if you walk an hour a day for 6 months
Answer: 65100 Calories
Step-by-step explanation:
Let's believe that there are 31 days in a month. Therefore, the number of days in 6 months will be:
= 31 × 6
= 186 days.
This means that the person will walk for 186 hours
The number of calories that will be burn will then be:
= 186 × 350
= 65100 calories
