What is the distance from Z= (16,−15) to the x-axis?
Answers
Answer:
15 units
Step-by-step explanation:
Distance from the x-axis is measured vertically, so you would look at the second number of the coordinates, the y value. Point Z is 15 units below the x-axis.
Hence, the distance from \(Z= (16,-15)\) to the x-axis is \(15\) units.
What is the axis?
An axis in mathematics is defined as a line that is used to make or mark measurements.
Here given that,
\(Z= (16,-15)\) which is on the x-axis.
So,
The shortest distance between the coordinate \((16,-15)\) and \((16,15)\).
Now, applying the distance formula
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
Here,
\((x_1,y_1)=(16,0)\\(x_2,y_2)=(16,-15)\)
Substituting these values in the formula
\(d=\sqrt{(16-16)^2+(-15-0)^2}\\\\d=\sqrt{(0)^2+(-15)^2}\\\\d=\sqrt{0+225}\\\\d=15\)
Hence, the distance from \(Z= (16,-15)\) to the x-axis is \(15\) units.

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answers
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

What is the median of the data set represented by the dot plot?
Answers
Answer: 5
Step-by-step explanation:
The median is the middle number of a group of numbers. So, to find the median, first, find out how many numbers there are. You can do this on the dot plot by counting the dots. There are 9 dots.
To find the middle number when the total is odd, you can drop the number down to an even number that will divide in half (or divide the number by two). In this case, you can drop the number to 8 and divide by two. The answer to that is 4. Because there was an odd number of dots, you should use the 4th and then the 5th numbers to determine the middle number. We also count the 5th number because the total was odd. If the total is even, use only one number as the middle number.
Since the 4th and the 5th number are lined up on the 5, that is the median number.
(If you ever have to find two numbers that are not lined up on the same number, you have to add those two numbers and divide by 2 to find the median.)

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?
Answers
Answer:
At least 714 numbers of widgets must be sold per day to make a profit.
Given fixed operating cost = $2,500 per day cost of widget =$ 1.50
widget sells =$ 5.00
Cost function = C(X)=1.50x+2500
Revenue function = R(X)=5 x
At Break Even point R (X) = C (X)5
X= 1.50X+2003.5
X =2500X =714
Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

You spin the spinner once. What is the probability of landing on a red space?
Answers
Answer:
\(\frac{8}{10}\), or 80% probability
Step-by-step explanation:
To determine probability, we need to know how many "options" there are. There are 2 white spaces, and 8 red spaces, so we have a total of 10 spaces.
Of those 10 spaces, 8 of them are red. As a fraction, this is \(\frac{8}{10}\), because 8 parts of the total ten are red.
To change this into a percent, we divide and then multiply by 100%.
\(\frac{8}{10}\)= .8*100%= 80%
If you don't have a calculator, remember that percepts are just a way to show a portion of 100. If we need to multiply 10 by 10 to get the total 100, we must also multiply the top of the fraction, which gives 80.
A photo of a beetle in a science book is increased to 778% as large as the actual size. If the beetle is 15 mm, what is the size of the beetle in the photo
Answers
Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.

a) 540 cubic inches
b)180 cubic inches
c) 280 cubic inches

Answers
Answer:
The correct answers is D
D) 360 cubic inches
Step-by-step explanation:
We know that the Area of the base of the can is given by
A = 45 inch²
Initial height of the can = 12 inches
Fraction of height cut off = 1/3
Calculate the final height after cutting off:
Find 1/3 of 12 inches:
\(\frac{1}{3}\cdot12=4\)
Subtract the answer from 12 to get final height:
Final height = 12- 4 = 8 inches
Can is a form of cylinder, so:
Volume = (Area)(height)
\(V=45\cdot8\\V=360inch^3\)
