Plug in the to X value in
Let
x------------> <span>the flags length
</span>y------------> the flags <span>width
P----------> perimeter
we know that
p=2x+2y------> 2x+2y=560----------> equation 1
and
x=y+40-------------> equation 2
</span> substitute 2 in 1<span>
2*(y+40)+2y=560-----------> 2y+80+2y=560--------> 4y=480------> y=120
x=y+40-------> 120+40----------> x=160
the answer is
</span>
the flags length is 160 ftthe flags width is 120 ft
Part 2) Write three
situation to which you could apply the resulting system of equations 1) It can be used when considering the relationship between the price of a product and the quantities of the product that people want to buy at a certain price.
2) It can be used to determine the speed, distance and time duration when traveling by car, and you want to know the values of the unknown variables in your trips.
3) It can be used to determine the most convenient loan option to buy a car or a house when considering the duration of the loan.
Answer:
30 mL/h
Step-by-step explanation:
You want the rate 336 ml in 11.2 h as a rate in simplest form.
<h3>Unit rate</h3>
The rate can be expressed in simplest form in a number of ways. We usually want rates involving time to be expressed with time units in the denominator:
(336 mL) / (11.2 h) = 30 mL/h
__
<em>Additional comment</em>
Medicine is often prescribed on a "per day" basis. In 24 hours, this rate would be ...
(30 mL/h)×(24 h/day) = 720 mL/day
The machine setup to dispense this medicine might use time units of minutes:
(30 mL/h) / (60 min/h) = (1/2) mL/min
Answer: For every 1 can of red paint, the number of yellow paints used by the painter is
and
There are approximately 29 cans of yellow paints for 34 cans of red paints.
Step-by-step explanation:
Since we have given that
Number of cans of red paint = 14
Number of cans of yellow paint = 12
According to question, we have to find that for every 1 can of red paint the painter uses what number of yellow paints;
Since the ratio of red paint to yellow paint is given by
![14:12\\\\7:6\\\\1:\frac{6}{7}](https://tex.z-dn.net/?f=14%3A12%5C%5C%5C%5C7%3A6%5C%5C%5C%5C1%3A%5Cfrac%7B6%7D%7B7%7D)
So, for every 1 can of red paint, the number of yellow paints used by the painter is ![\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D)
Similarly,
If Number of can of red paint is used = 34
So, Number of cans of yellow paint will be
![\frac{6}{7}\times 34\\\\=\frac{6\times 34}{7}\\\\=29\ approx.](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D%5Ctimes%2034%5C%5C%5C%5C%3D%5Cfrac%7B6%5Ctimes%2034%7D%7B7%7D%5C%5C%5C%5C%3D29%5C%20approx.)
Hence, there are approximately 29 cans of yellow paints for 34 cans of red paints.
