A trapezoid has a height of 12 inches, a base length of 9 inches, and an area of 150 square inches. What is the length of the other base?
The length of other base is 16 inch.
The area of trapezoid is given by the formula -
Area = 1/2×(a+b)×height, where a and b represents the two different bases. Let a be the length of 9 inches and b be the length of other base.
150 = 1/2×(9 + b)×12
Shifting 2 to Left Hand Side and performing multiplication on both sides.
150×2 = (9 + b)×12
300 = 108 + 12b
12b = 300 - 108
12b = 192
Shifting 12 to Right Hand Side of equation to find the other base
b = 192 ÷ 12
Performing division
b = 16 inch
Hence, the length of other base is 16 inch.

Your answer would be the second one.
We know that adding [tex]\frac{1}{2}[/tex] to x gives us 4, as that's provided by the question.
So [tex]4=x+\frac{1}{2}[/tex]. Now, to find x, simply subtract [tex]\frac{1}{2}[/tex] from 4 to give us x, which gives us [tex]3\frac{1}{2}[/tex].
Evaluate each expression for x=-2,0,1 , and 4.

Identify each sequence as arithmetic, geometric, or neither. Then find the next two terms. 45,90,180,360, .............
45,90,180,360, .... is a geometric sequence. The next two terms are 720, 1440.
In an arithmetic sequence, the difference between two subsequent terms is constant. This difference between two subsequent terms is usually called common difference (d), and its value is:
d = a(n) - a(n-1)
Where a(n) is the nth term and a(n-1) is the (n-1)-th term.
In a geometric sequence, the ratio (r) between two subsequent terms is constant.
r = a(n)/a(n-1)
The given sequence is: 45,90,180,360, .....
We can check that:
(90 - 45) is not equal to (180 - 90) and to (360 - 180)
So, there is no common difference in the given sequence.
Let us now check the ratio:
90/45 = 180/90 = 360/180 = 2
The ratio between two subsequent terms is constant, that is 2. Therefore, we can conclude that the given sequence is a geometric sequence with a(1) = 45 and r = 2.
In a geometric sequence, the next term is obtained by multiplying the current term by its ratio.
Hence, the next two terms are calculated as:
360 x 2 = 720
720 x 2 = 1440
or 720, 1440.

Please see the Venn diagram.
P(B) [the entire blue circle] = 0.6 is the probability of such a family vacationing there at beach.
P(B∩M) [the red/blue intersecting intersection of two circles] = 0.2 is the possibility of a family taking a vacation in both locations.
Using the property of independent event: Two events are considered independent if the incidence of one does not affect the likelihood of occurrence of the other.
As, occurrence of family visiting the beach will also visit the mountains is an independent event. Thus,
The formula for the independent event is;
P(B | M) = P(B∩M)/P(B)
P(B | M) = 0.2/0.6
P(B | M) = 0.33

ions (in mol/L) in lime juice, to the nearest hundredth? Use the
formula pH = -log[H +].
Answer:0.02 mol/L
Step-by-step explanation:
Given: pH = 1.7
Required: [H+]
Equation: pH = -log [H+]
Solution:
Take the antilog of both sides
[H+] = antilog(-pH)
Antilog(-pH) is equal to 10^-pH. Therefore
[H+] = 10^-pH
Solve for [H+]
[H+] = 10^-1.7
Answer: [H+] = 0.02 mol/L

Answer: 0.4You stand on a street corner and record the gender of the first twelve people who pass by. if the city is half male and half female, what is the probability that you will record all females?
The probability is 6.
Probability is the possibility of an event occurring. We can scale the probability of an event between 0 and 1. 0 refers to an improbable event, and one refers to an event with the highest possibility. The type of probability we will use to solve this problem is the geometric distribution.
The geometric distribution is defined as a discrete probability distribution representing the probability of consecutive failures before success in a Bernoulli trial. There could be only two possible outcomes; either True (1) or False (0).
Bernoulli's trial is an experiment in which we have only two possible outcomes, success or failure. In other words, the geometric distribution repeats Bernoulli trials until it succeeds, then stops. So, achieving success is the ultimate goal and is the point that stops Bernoulli's trials from happening further.
Geometric distribution, the class of probability distributions, is based on three key assumptions, and these assumptions are defined as:
The studies conducted are independent. Each event is independent of the other.Each attempt has only two outcomes: success or failure. If an event has any other possible outcome other than 0 and 1, it can not be classified as a Bernoulli trial.The probability of success, indicated by p, is the same for each trial.Now for our given problem, we stand on a street corner and record the gender of the first twelve people who pass by. The condition here is the city is half male and half female. Now to find the probability, we will consider the possibility of each of the twelve events. Since half of the population is Female, the probability of one single event is;
p = 1/2 (50 %)
The overall probability is the sum of all the individual probabilities:
P ( ALL FEMALE)
= 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2 + 1 / 2

Write the equation of the line that passes through the points (3, 5) and (6, 7). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.
HELP PLEASEEE
Answer:
We can use the point-slope form of the equation of a line to find the equation that passes through the points (3, 5) and (6, 7).
The point-slope form of a line is:
y - y1 = m(x - x1)
where (x1, y1) is one of the points on the line and m is the slope of the line.
First, we need to find the slope of the line using the two given points. The slope formula is:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the two points.
Plugging in the values we know, we get:
m = (7 - 5) / (6 - 3) = 2 / 3
So the slope of the line is 2/3.
Now we can use one of the given points and the slope to write the equation of the line in point-slope form. We'll use the first point, (3, 5).
y - 5 = (2/3)(x - 3)
This is the equation of the line in point-slope form.
If we want to write it in slope-intercept form (y = mx + b), we can simplify:
y - 5 = (2/3)x - 2
y = (2/3)x + 3
So the equation of the line that passes through the points (3, 5) and (6, 7) is y = (2/3)x + 3.
Explain the difference between a constant and a coefficient.
The constant is the number that includes in the expression and the coefficient is the number that write along with the variable in the expression.
Here,
The constant is the number that includes in the expression. It is a fixed value that does not change over time
Example : 2x+5
Where 5 is the constant
The coefficient is the number that write along with the variable in the expression
Example : 2x+5
Where 2 is the coefficient.
Hence, the constant is the number that includes in the expression and the coefficient is the number that write along with the variable in the expression.
