Step-by-step explanation:
Answer:
13.7 inches
Step-by-step explanation
Area = base*height
(since it's a square, the lengths of all four sides of the board are equal. therefore, we can write the equation above like the following)
Area of square = side length^2
(square root both sides of the equation, and you get the following)
[tex]\sqrt{Area\\}[/tex] = side length
(now, substitute the info)
[tex]\sqrt{188\\}[/tex] = x
(solve)
x = 13.7 inches

Two cars start out at the same point and at the same time one starts driving north while the other starts driving east at a speed that is 10 mph faster than the car driving north. 12 hours after the cars start driving they are 600 miles apart. What was the speed of each car?
Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,
(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.
if the 3rd and 9th term of an ap are 4 and -8 respectively then which term of AP is zero
Answer:
fifth term
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₃ = 4 and a₉ = - 8 , then
a₁ + 2d = 4 → (1)
a₁ + 8d = - 8 → (2)
Subtract (1) from (2)
6d = - 12 ( divide both sides by 6 )
d = - 2
Substitute d = - 2 into (1)
a₁ + 2(- 2) = 4
a₁ - 4 = 4 ( add 4 to both sides )
a₁ = 8
Thus equating the n th term formula to zero and solving for n
8 - 2(n - 1) = 0 ( subtract 8 from both sides )
- 2(n - 1) = - 8 ( divide both sides by - 2
n - 1 = 4 ( add 1 to both sides )
n = 5
The fifth term is equal to zero
2. How do you find P(A or B) if A and B are independent events for one action, such as spinning a four-color spinner once and finding P(red or blue)?
Answer:
P(red or blue) = [tex]\frac{7}{16}[/tex].
Step-by-step explanation:
We have to find P(A or B), if A and B are independent events for one action, such as spinning a four-color spinner once.
Firstly, as we know that the formula for finding P(A or B) is given by;
P(A or B) = P(A) + P(B) - P(A and B)
Since it is stated that event A and B are independent, this means that there is no dependence of any one event on another event, so;
P(A and B) = P(A) [tex]\times[/tex] P(B)
Now, we can find P(A or B) = P(A) + P(B) - P(A) [tex]\times[/tex] P(B); is we know that the probabilities of happening of both events.
Similarly, P(red or blue) = P(red) + P(blue) - P(red) [tex]\times[/tex] P(blue).
Since the event is spinning a four-color spinner once and assuming there are four different colors, so the probability of wheel stopping on each color is ([tex]\frac{1}{4}[/tex]).
So, P(red or blue) = [tex]\frac{1}{4} +\frac{1}{4} -(\frac{1}{4} \times \frac{1}{4} )[/tex]
= [tex]\frac{2}{4} -\frac{1}{16}[/tex] = [tex]\frac{7}{16}[/tex].

[tex] \frac{2}{7} (x - 2) = 4x[/tex]Multiply through by 7 inorder to clear out the fraction
That's
[tex]2 \times \frac{2}{7} (x - 2) = 4x \times 7[/tex]We have
[tex]2(x - 2) = 28x[/tex]Multiply the terms in the bracket
That's
2x - 4 = 28x
Subtract 28x from both sides
We have
2x - 28x - 4 = 28 - 28x
Simplify
- 26x = 4
Divide both sides by - 26
That's
[tex] \frac{ - 26x}{ - 26} = - \frac{4}{26} [/tex]We have the final answer as
[tex]x = - \frac{2}{13} [/tex]Hope this helps you

The table shows the estimated number of lines of code written by computer programmers per hour when x people are working. A 2-column table with 6 rows. The first column is labeled people working with entries 2, 4, 6, 8, 10, 12. The second column is labeled lines of code written hourly with entries 50, 110, 160, 210, 270, 320. Which model best represents the data?
Answer:
We make the table of these values at different values of x.

10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
Step-by-step explanation:
Considering the situation described, it is found that a linear model best represents the data, because there is a relatively consistent additive rate of change.
When to use a linear model and when to use an exponential model?If the rate of change is additive, that is, the difference between consecutive terms is the same, a linear model is used.If the rate of change is multiplicative, that is, the quotient between consecutive terms is the same, an exponential model is used.In this problem, when the input changes by 2, the output always increases between approximately 50 and 60, that is, the same values, hence a linear model best represents the data, because there is a relatively consistent additive rate of change.

a rectangle has a width w and it's length is 3w-2. if the area is 65ft^2, find the length and width of the rectangle.
Answer:
Width = 5
Length = 13
Step-by-step explanation:
Area of a rectangle:
=> L x W = Area
After knowing this, we could find the factors of 65
=> 65 = 5 x 13, 1 x 65
So, the only way is 5 x 13.
So, Width = 5
Length = 13
Let's check whether our answer is correct.
=> (3w - 2) * w = 65
=> (3 (5) - 2) * 5 = 65
=> (15 - 2) * 5 = 65
=> 13 * 5 = 65
=> 65 = 65
So, our answer is correct.
three signals that beep.
signal a beeps every 25 seconds
signal b beeps every 30 seconds
signal c beeps every 100 seconds.
The three signals start beeping at the same time.
How many times in one hour will the three signals beep?
Answer:
The number of times signal a beeps in 1 hour = 144 times
The number of times signal b beeps in 1 hour = 120 times
The number of times signal c beeps in 1 hour = 36 times
The number of times three signals bee in one hour = 12 times
Step-by-step explanation:
The given parameters are;
The period for each signals beep are;
Signal a beeps every 25 seconds
Signal b beeps every 30 seconds
Signal c beeps every 100 seconds
Therefore, in one hour, signal a will beep 1× 60 × 60/25 = 3600/25 = 144 times
In one hour, signal b will beep 1×60×60/30 = 3600/30 = 120 times
In one hour, signal c will beep 1×60×60/100 = 3600/100 = 36 times
Therefore, we have;
The number of times signal a beeps in 1 hour = 144 times
The number of times signal b beeps in 1 hour = 120 times
The number of times signal c beeps in 1 hour = 36 times
From Excel, we can see that the three signals beep the same time at 300, 600, 900, 1200, 1500, 1800, 2100, 2400, 2700, 3000, 3300, and 3600
The number of times three signals bee in one hour = 12 times
signal a beeps every 25 seconds
signal b beeps every 30 seconds
signal c beeps every 100 seconds.
Answer to the above questions is 300,600,900 if the signal beep at the same time 12 times
Explanation to the above questions
One hour contains 3600 secondsSignal a beep 3600/25=144Signal b beep 3600/30=120signal c beep 3600/100=36At the same time all the signal beep than 144+120+36=300we conclude that it will beep 12 times because 300,600,900,1200,1500,1800,2100,2400,2700,3000,3300,3600

In the polynomial below, what number should replace the question mark to produce a difference of squares? X^2 + ?x -49 A. 0 B. 14 C. 49 D.7
Answer:
A
Step-by-step explanation:
The difference of squares formula is a² - b² = (a + b)(a - b). We want this polynomial to be in the form a² - b². We notice that x² and 49 are perfect squares already which means that we don't need the x term. To get rid of it, its coefficient must be 0 because 0 times anything is 0, thus the x term will be removed and we'll be left with x² - 49 which is a difference of squares.

5x/6 + y/3 = 4/3
2x/3 - y/2 = 11/6
Answer:
x = 2
y = - 1
Step-by-step explanation:
5x/6 + y/3 = 4/3
2x/3 - y/2 = 11/6
Multiply the above equation by 6 to express in linear form
6 × (5x/6 + y/3 = 4/3)
5x + 2y = 8.... (1)
6 × (2x/3 - y/2 = 11/6)
4x - 3y = 11.... (2)
Thus, the equation are:
5x + 2y = 8.... (1)
4x - 3y = 11.... (2)
Next, multiply equation (1) by 3 and equation (2) by 2. This is illustrated below:
3 × (5x + 2y = 8)
15x + 6y = 24 ..... (3)
2 × (4x - 3y = 11)
8x - 6y = 22 ... (4)
Next, add equation 3 and 4 together. This is illustrated below:
.. 15x + 6y = 24... (3)
+ 8x - 6y = 22 .... (4)
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
23x = 46
Divide both side by 23
x = 46/23
x = 2
Next, substitute the value of x into any of the equation. Here, we shall substitute the value of x into equation (3). This is illustrated below:
15x + 6y = 24... (3)
x = 2
15(2) + 6y = 24
30 + 6y = 24
Collect like terms
6y = 24 - 30
6y = - 6
Divide both side by 6
y = - 6/6
y = - 1
Therefore, the value of x and y is
x = 2
y = - 1
