g Find two positive numbers whose sum is 380 and whose product is a maximum. You MUST use optimization methods to solve this.
Answer:
The first number is 190 and the second number is also 190
Step-by-step explanation:
let the first number = x
let the second number = y
The sum of the numbers is given by;
x + y = 380
y = 380 - x
The objective function is given by;
F = xy
F = x(380 -x)
F = 380x - x²
Take the derivative of the function;
F' = 380 - 2x
Find the critical points;
380 - 2x = 0
2x = 380
x = 380 / 2
x = 190
Determine the second number, y;
y = 380 - x
y = 380 - 190
y = 190

If the Internet consisted of four computers, there would be six possible connections. If it consisted of five computers, there would be ten possible connections. How many connections are possible with twenty computers
Answer:
80 possible connections
Step-by-step explanation:
Let the constant k = change in possible connection/number of computers
change in possible connections = 10 - 6 = 4
change in number of computers = 5-4 = 1
k = 10-6/5-4
k = 4/1
k = 4
Since k = possible connections/number of computers:
4 = possible connections/20
possible connections = 4 * 20
possible connections = 80
Hence the possible number of connections with 20 computers are 80 connections
find the angle of y dasdwadasdaw
Answer:
C
Step-by-step explanation:
Since angles x and y lie on a single straight line,
∠x +∠y= 180° (adj. ∠s on a str. line)
Given that ∠x= 42°,
42° +∠y= 180°
∠y= 180° -42° (-42° on both sides)
∠y= 138° (simplify)
Thus, option C is correct.
A line passes through the point (4,-6) and has a slope of -3/4which is the equation of the line?
Answer:
y=(-3/4)+3
Step-by-step explanation:
Steve types at a rate of 45 words per minute. He writes an equation relating the number of words he can type, w, to the number of minutes he spends typing, m. w = 45m Xena doesn’t know the number of words per minute that she can type. But she recorded the time it took her to type different numbers of words in this table.
minutes words
02 100
04 200
08 400
Answer:
50 words per minute
Step-by-step explanation:
If in 2 minutes she can type 100, that means you must divide 100 by 2. 100 divided by 2 equals 50. You can check this by doing the same with 200 words in 4 minutes by dividing 200 by 4 to get 50. Xenas equation would be w=50m
Her average typing rate is 50 words per minute.
Here,
To find out Xena's typing rate (words per minute), we can use the data she recorded in the table.
We can calculate her typing rate by dividing the number of words she typed by the time it took her to type those words.
Let's perform the calculations:
For the first row (2 minutes, 100 words):
Typing rate = Words / Time
= 100 words / 2 minutes
= 50 words per minute
For the second row (4 minutes, 200 words):
Typing rate = Words / Time
= 200 words / 4 minutes
= 50 words per minute
For the third row (8 minutes, 400 words):
Typing rate = Words / Time
= 400 words / 8 minutes
= 50 words per minute
As we can see from the calculations, Xena's typing rate is consistent at 50 words per minute for all the recorded data.
Therefore, her average typing rate is 50 words per minute.

Johnny has a math test on Friday, an English test on Tuesday, and a social studies quiz on Wednesday. Over the weekend, he read 20 books. He needed to read 5 books for his English test and 2 books for his social studies quiz. A week later, Johnny received a 92 on his math test, 84 on his English test, and a 90 on his social studies quiz. What percent of books did Johnny read that were for social studies? Round to the nearest whole number (percentage). Do not include % in your answer. For example, if the answer is 19%, enter 19.
Answer: The percent of books did Johnny read that were for social studies=10%
Step-by-step explanation:
Given: Total books he read -= 20
Number of books for social studies = 2
The percent of books did Johnny read that were for social studies
[tex]=\dfrac{\text{Number of social studies books}}{\text{Total books}}\times100\\\\=\dfrac{2}{20}\times100\%\\\\=\dfrac{100}{10}\%=10\%[/tex]
Hence, the percent of books did Johnny read that were for social studies=10%

Answer:
circumference = 150.72cm
area = 1808.64cm²
Step-by-step explanation:
the formula for circumference = 2πr
the formula for area = πr²
24cm is the radius (r)
so therefore
circumference = 2(3.14)(24)
= 150.72cm
area = (3.14)(24)²
= 1808.64cm
