What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
The given statement is,
the difference between nine times a number and one more than five times the number
Let x be the number.
Thus, we have
nine times a number = 9x
one more than five times the number = 1 - 5x
Thus, the numerical expression we get is
9x + (1 - 5x)
Expanding we get
9x + 1 - 5x
Solving we get
4x + 1
this is the required expression
Thus, the required expression for the given statement is 4x + 1.

Use the segment addition postulate to solve for the length of BC, if AC = 16, BC = x + 11, and AB = 3x-7.
. If C lies between A and B on AB, then AC + CB = AB. What can you logically conclude about AB?
Answer: AB is twice the size of AC and twice the size of CB
Step-by-step explanation: "Lies between" means that it's in the middle. C is in the middle of A and B. A to C would be the same distance of C to B because C seperates the segments into 2 equal halves. AB is the whole segment including C, you could do AC + AC if you substituted it for the lengths and you would still get AB

The zookeeper mentioned that the scale used to weigh some of the larger animals can be off by 12 pounds. The scale read 438.2 lbs. for one of the larger animals. If the animal’s actual weight is x pounds, write an expression to represent the number of pounds the weight on the scale is from the actual weight of the animal. Then explain the range of values in which the actual weight might be.
The actual weight of the animal is between 450.2 and 426.2 pounds
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Inequality can be used to show that two variables or numbers are not equal to each other.
The weight of the larger animals can be off by 12 pounds. Let x represent the actual weight of the animal. If the scale reads 438.2 lbs, hence:
|x - 438.2| = 12
x - 438.2 = 12; or -(x - 438.2) = 12
x = 450.2; or x = 426.2
The actual weight of the animal is between 450.2 and 426.2 pounds

The average rate of change from x=1 to x=3 is -1
How to find the average rate of change from x=1 to x=3?On the given graph, we have the following function values
f(1) = 6
f(3) = 4
The average rate of change from x=1 to x=3 is then calculated as
Rate = [f(3) - f(1)]/[3 - 1]
This gives
Rate = [4 - 6]/[3 - 1]

Answer:
4a.) 0.0005 = 5 x 10 to the exponent -4
4b.) 0.0025 = 2.5 x 10 to the exponent -3
5a.) 2 x 10 to the exponent -2 = 0.02
5b.) 16 x 10 to the exponent -4 = 0.0016
Tip:
The number being multiplied has to be less than or equal to 10. Count the places the decimal point moves from the end of the number to the number in the original equation.
Example: 0.05 = 5 x 10 to the exponent -2
0.05 has 2 spaces for the decimal point to move up to 5 going right. We use a negative decimal because 0.05 is less than 5. Here is an example where the exponent is positive:
5000 = 5 x 10 to the exponent 3
5000 has 3 spaces for the decimal point to move down to 5 going left.

Find the average rate of change of f (x)=x-2√x on the interval [1, 9].
The average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.
What is average rate of change?It is a measure of how much the function changed per unit, on average, over that interval.
We have,
f(x) = x - 2√x
On the interval [1,9].
[1, 9] = [a, b]
The average rate of change:
= f(b) - f(a) / b - a
= f(9) - f(1) / 9 - 1
= [(9 - 2√9) - (1 - 2√1)] / 8
= [ (9 - 6) - (1 - 2) ] / 8
= (3 + 1) / 8
= 4 / 8
= 1/2
Thus the average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.

What is the experimental probability that the next person to sign up will have blue eyes?
Write your answer as a fraction or whole number.
P(blue)=
The experimental probability of next person to have Blue eyes is 3/7.
Probability :Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
It is based on the possible chances of something to happen.
Probability (P) = Number of a Favourable outcome {n (E)} / Total number of outcomes {n (S)}
Simply, P = n (E) / n (S)
Given, Eye colors of the people
Green = 2
Blue = 30
Brown = 38
To find the probability of next person to have blue eyes, first we will add the given eye colors
Total number of Eye Colors = 2 + 30 + 38 = 70
Number of Blue Eyes = 30
Then, Probability to have blue eyes P(blue) = Number of Blue Eyes / Total number of Eye Colors
= 30/70
= 3/7
So, there is 3/7 chances to next person to have blue eyes.

In the lab, Miguel has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as Solution B. Solution A is 12% alcohol and Solution B is 16% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 120 milliliters of pure alcohol? Number of milliliters of Solution B: X Ś
Miguel uses 300 mL Solution B and 600 mL Solution A.
What is termed as the percentages?A percentage is a relative value that symbolizes the hundredth part of any quantity.One percent (symbolized 1%) is one hundredth part; thereby, 100 percent symbolizes the entire amount as well as 200 percent clarifies twice the given amount.Let x represent the amount of Solution B used.
2x = the quantity of Solution A used.
Solution A is alcohol = 12%.
Solution B is alcohol = 16%.
Given that 12% = 0.12 and 16% = 0.16, we can calculate the following equation:
2x(0.12) + x(0.16) = 120 (Recall that pure alcohol has a concentration of 100% = 1.00.)
0.24x + 0.16x = 120
0.40x = 120
x = 300 mL
Thus, Miguel makes use of 300 mL of Solution B and 2(300) = 600 mL of Solution A.
