Answer:
It is correct because the smallest one is 3 the second one all together is 15 and the last one is 60.
Step-by-step explanation: Basically you can divide the 60 with 15 and you can divide 60 with 3.
60/15 = 4
60/3 = 20
and 4 can go in to 20 5 times so yeah.

the area of a square is 400 units. if the length of each side of the square increased by one unit, would its area be a rational number
Answer:
Yes, the area of the square would be a rational number.
Step-by-step explanation:
Area of square = 400 units² = x²
x = one side length of square
x = √400 = 20 units
Increase each side length by 1 unit.
New side length = 21 units
Area of new square = 21² = 441
441 is a rational number because the square root of 400 is a rational number.
√400 = 21
Therefore: If the length of each side of the square increased by one unit, the area of the square would be a rational number. The area of the square would still be a perfect square.

There are 20 black, 15 white, 12 green, 12 red, 9 blue and 2 yellow candies in a box. How many candies should you take (without looking at them) to be sure that you have at least 3 candies the same color?
=============================================================
Explanation:
The best case scenario is that you get 3 of the same color in a row on the first three attempts. The lower bound is 3.
However, we have to consider the worst case scenario when we want to guarantee something like this, without looking at the candies we selected.
Consider the case of something like this sequence:
blackwhite greenredblueyellowblackwhitegreenredblueyellowblackAs you can see above, I've listed the colors in the order presented by your teacher. I pick one candy at a time. Once I reach yellow, I restart the cycle. In slots 1, 7 and 13, we have a black candy selected. This example shows that we must make 13 selections to guarantee that we get at least 3 candies of the same color (that color being black). The order of the candies selected doesn't matter. We could easily use any other color except yellow to do this example. The black candy just happened to be the first listed, so I went with that.
Note how we have 6 unique colors in the set {black, white, green, red, blue, yellow}. If we pick 2 candies of each color, then we've selected 6*2 = 12 candies so far. That 13th candy (some color other than yellow) is guaranteed to be a color we already selected; therefore, we'll be guaranteed to have 3 of the same color. We won't know what color it is but we will know we have a match like this.

A little help? A set of numbers is given below. √72, 9.25, √83, 2, 8.7 Which list correctly orders the numbers from least to greatest?
Answer:
2, √72, 8.7, √83, 9.25
Step-by-step explanation:
First, you need to find the integers of each number that is not already a integer.
Square root of 72: 8.48528137424
9.25
Square root of 83: 9.11043357914

The equation y=1/9x represents the distance y, kilometers, that Patrick traveled in x minutes while training for the cycling portion of a triathlon. The table shows the distance y Jennifer traveled in x minutes in her training. Who has the faster training rate?
Answer:
Jennifer has the faster training rate.
Step-by-step explanation:
In order to determine the equation that represents the distance, y (in kilometers), that Jennifer traveled in x minutes:
Choose two ordered pairs from the table: (5, 40) and (64, 8).
Let (x1, y1) = (40, 5)
(x2, y2) = (64, 8)
Substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (8 - 5)/(64 -40)
m = 3/24 = 1/8
Therefore, y = 1/8x represents the distance, y (in kilometers), that Jennifer traveled in x minutes.
In order to find out who has the faster training rate, choose one of the given x values from the table, and substitute it into Patrick's and Jennifer's equations:
Let x = 40:
Patrick:
y = 1/9x
y = 1/9(40)
y = 4.44 km ⇒ This represents the distance that Patrick traveled in 40 minutes.
In contrast, Jennifer traveled for 5 kilometers in 40 minutes (according to the given table). She reached a farther distance than Patrick, given their training time of 40 minutes.
Therefore, Jennifer has the faster training rate.

a helicopter flies over a city the helicopter changes it's altitude by -42.9m. then it changes it's altitude by another -15.4m what is the total change in the helicopters altitude
Answer:
The total change in the helicopter's altitude is [tex]-58.3[/tex].
Step-by-step explanation:
Create an equation.
[tex]-42.9 +(-15.4)[/tex]
Adding two negative numbers is always negative, so simply add the absolute values and make the answer a negative.
[tex]42.9+15.4 = 58.3[/tex]
Now, change the answer to a negative.
[tex]-58.3[/tex]
Thus, [tex]-58.3[/tex] is the answer.
Determine the x-intercept points of the function h(x) = (x – 5)(x – 6).
Answer:
(5,0),(6,0)
Step-by-step explanation:
The x-intercept occurs when h(x) = 0
∴ let 0 = (x – 5)(x – 6) [using the knowledge that for the
produc to be 0, one of terms
must be zero]
⇒ x - 5 = 0 ; x - 6 = 0 [solve for x in each case]
⇒ x = 5 ; x = 6
∴ the points of the x-intercept are (5, 0) & (6, 0)Check:
If we graph the line we can see whether the intercepts are truly (5, 0) and (6,0). As seen below in the Desmos graph, it is.
write the equation of a line that is parallel to y=12-5x and passes through the point (1,-7)
Answer:
y= -5x-2
Step-by-step explanation:
Parallel equations have the same slope, so we know our slope will be -5. To get our y-intercept, we need to plug in our slope. 1 times -5 is -5, so we need to figure out how to get from -5 to -7. We're going to subtract 2, so the y-intercept is -2.
The equation of the line parallel to y=12-5x and passes through the point (1,-7) will be y= -5x-2.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the equation of a line that is parallel to y=12-5x and passes through the point (1,-7).
The slope of the parallel lines is always the same. The slope of the line will be -5.
The y-intercept of the line will be calculated as,
y = mx + c
-7 = -5(1) + c
c = -7 + 5
c = -2
The equation of the line will be written as,
y = mx + c
y = -5x - 2
Therefore, the equation of the line parallel to y=12-5x and passes through the point (1,-7) will be y= -5x-2.

If the heights of a population of men are approximately Normally distributed, and the middle 99.7% have heights between 5'0" and 7'0", what is the standard deviation of the heights of the population?
a. 1"
b. 12"
c. 6"
d. 4"
e. 3"
Answer:
4 inches
Step-by-step explanation:
the middle number is 6 and the distance from 99.7 from the middle is 3 standard deviations. 12/3 =4
The value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean. The correct option is e.
What is the empirical rule?If your distribution follows a normal distribution, the standard deviation and mean can tell you where the majority of the data are.
It is given that the heights of a large population of ostriches are normally distributed. The percentage of these heights is within 3 standard deviations of the mean.
As we know from the empirical rule:
It is the rule of 68-95-99.7.
From the data given in the question: The height of a large population of ostriches is normally distributed.
X ~ (u, б²)
Normal distribution.
P{u - 3б < X < u + 3б}
From the distribution table:
P{u - 3б < X < u + 3б} = 99.7%
Thus, the value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean.

To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
