Solve the inequality:
8 + 4x ≥ 12
A. x ≥ 1
B. x ≥ 5
C. x ≤ 5
D. x ≤ 1
Answer:
x ≥ 1
Step-by-step explanation:
8 + 4x ≥ 12
Subtract 8 from each side
8-8 + 4x ≥ 12-8
4x ≥ 4
Divide by 4
4x/4 ≥ 4/4
x ≥ 1
The solution to the inequality 8 + 4x ≥ 12 is x ≥ 1. Therefore, the correct answer is A. x ≥ 1.
Correct option is A.
To solve the inequality 8 + 4x ≥ 12, we need to isolate x. Here's how we do it step by step:Start with the given inequality: 8 + 4x ≥ 12.First, subtract 8 from both sides of the inequality to isolate the term with the variable:8 + 4x - 8 ≥ 12 - 8.Simplify both sides:4x ≥ 4.Now, divide both sides by 4 to solve for x:(4x)/4 ≥ 4/4,x ≥ 1.So, the solution to the inequality is:x ≥ 1.Now, let's match this solution to the given answer choices:A. x ≥ 1 - This matches our solution.B. x ≥ 5 - This is not correct.C. x ≤ 5 - This is not correct.D. x ≤ 1 - This is not correct.The correct answer is A. x ≥ 1.For more questions on inequality -

The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. Find the probability that exactly one of the eggs is cracked. Write the entire decimal answer.
Answer:
Probability that exactly one of the eggs is cracked is 0.0198.
Step-by-step explanation:
We are given that the probability that an egg on a production line is cracked is 0.01.
Two eggs are selected at random from the production line.
The above situation can be represented through binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number trials (samples) taken = 2 eggs
r = number of success = exactly one
p = probability of success which in our question is probability that
an egg on a production line is cracked i.e; p = 0.01
Let X = Number of eggs on a production line that is cracked
So, X ~ Binom(n = 2, p = 0.01)
Now, probability that exactly one of the eggs is cracked is given by = P(X = 1)
P(X = 1) = [tex]\binom{2}{1} \times 0.01^{1} \times (1-0.01)^{2-1}[/tex]
= [tex]2 \times 0.01 \times (0.99)^{1}[/tex]
= 0.0198
Therefore, the probability that exactly one of the eggs is cracked is 0.0198.

The librarian was checking the thicknesses of several books and found that the average thickness of a book was 1.8 centimeters. She found this by averaging the thicknesses of five different books. Four of the thicknesses were 1.4 cm, 1.9 cm, 2.1 cm, and 2.4 cm. What was the thickness of the fifth book that she measured?
Answer:
1.2 cm
Step-by-step explanation:
1.8 * 5 = 9
9 - (1.4 + 1.9 + 2.1 + 2.4) = 1.2
1.2 + 1.4 + 1.9 + 2.1 + 2.4 = 9
9/5 = 1.8
Two different websites offer the same watch for sale. The watch costs $45 on both sites. The site, Watches for Less charges a shipping fee of 4% of the cost of the watch. The site, Tick Tock charges 2.5% of the cost of the watch for shipping. How much less will the total cost of the watch be if purchased from Tick Tock?
Round your answer to the hundredths place.
Final answer:
The total cost of the watch will be $0.67 less if purchased from Tick Tock.
Explanation:
To find out how much less the total cost of the watch will be if purchased from Tick Tock, we need to calculate the shipping fee for both websites and subtract that amount from the total cost.
For Watches for Less, the shipping fee is 4% of $45, which is $1.80.
For Tick Tock, the shipping fee is 2.5% of $45, which is $1.13.
Therefore, the total cost of the watch from Tick Tock will be $45 - $1.13 = $43.87. The total cost from Watches for Less will be $45 - $1.80 = $43.20.
The difference in the total cost is $43.87 - $43.20 = $0.67.
Therefore, the total cost of the watch will be $0.67 less if purchased from Tick Tock.
Harry bought a used dirt bike for $1,050. Before purchasing the bike, Harry had a total of
$2,250 in his savings account. What percentage of his savings account did Harry spend on
the dirt bike?
Answer:
. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Step-by-step explanation:
Final answer:
Harry spent 46.67% of his savings on the dirt bike, calculated by dividing the price of the dirt bike by the amount in his savings account and then multiplying by 100.
Explanation:
The question is asking how to calculate the percentage of Harry's savings that was spent on a dirt bike. To find the percentage, you would divide the amount spent on the dirt bike by the total amount in the savings account and then multiply by 100. Harry spent $1,050 on the dirt bike and had $2,250 in his savings account originally.
Here's the step-by-step calculation:
Divide the cost of the dirt bike by the total savings: $1,050 / $2,250.You get a decimal result from step one, which you then multiply by 100 to get a percentage.The calculation is ( $1,050 / $2,250 ) × 100 = 46.67%.Therefore, Harry spent approximately 46.67% of his savings on the dirt bike.Chris says that 3/4 is halfway between 0.5 and 100%. is he correct
Answer:
Yes!
Step-by-step explanation:
0.5 is half, and 1.00 is whole so 3/4 would be correct because it is in between 0.5 and 1.00
Yes, Chris says that 3/4 is halfway between 0.5 and 100%.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
Chris says that 3/4 is halfway between 0.5 and 100%.
Midway of 0.5 and 1 is,
(1 + 0.5)/2 = 0.75
100% as a decimal is 1.0.
That means,
3/4 = 0.75.
0.5 < 0.75 < 1
Therefore, Chris is correct.

Devora tested two engines. As each engine's rotation got faster, its temperature increased at a constant rate.
The first engine's temperature (in degrees Celsius) as a function of its rotation speed (in cycles per second) is given by the following table of values:
The Table is for the first engine below
For the second engine, the graph is below
The temperature of which engine increased more for each increase of 1 cycles per second?
Choose 1 answer:
(Choice A)
A
The first engine
(Choice B)
B
The second engine
(Choice C)
C
The temperatures of both engines increased the same
Which engine was hotter when it rotated at 20 cycles per second?
Choose 1 answer:
(Choice A)
A
The first engine
(Choice B)
B
The second engine
(Choice C)
C
Both engines were equally hot
To compare the rates of temperature increase for the two engines, you can look at the slopes of their temperature vs. rotation speed graphs. To determine which engine was hotter at a rotation speed of 20 cycles per second, you can compare the corresponding temperature values on the graphs.
Explanation:The question asks which engine's temperature increases more for each increase of 1 cycle per second. To determine this, we need to compare the rates of change of temperature for both engines. The rate of change of temperature for the first engine can be determined by finding the slope of the temperature vs. rotation speed graph. From the graph, it can be seen that the slope of the line connecting two points on the graph represents the rate of change of temperature per unit increase in rotation speed. By comparing the slopes of the two graphs, we can determine which engine's temperature increases more for each increase of 1 cycle per second.
To determine which engine was hotter when it rotated at 20 cycles per second, we can look at the corresponding temperature values on the graph. By finding the temperature value for each engine when the rotation speed is 20 cycles per second, we can compare the two temperatures to determine which engine was hotter.
Julius needs to determine how much information needs to be given about an isosceles triangle to be able to draw an isosceles triangle. He is looking at six different cases and is trying to determine if that amount of detail will allow him to construct just one isosceles triangle or if it allows for more than one isosceles triangle.
To uniquely construct an isosceles triangle, you would either need the lengths of two sides and the angle between them, two sides and the angle opposite to one of them, or two angles and any side.
Explanation:Julius is examining the principles of constructions in geometry. To construct a unique isosceles triangle, certain specific information is needed. An isosceles triangle is a triangle with two sides of equal length, and the angles opposite these sides are of equal measure too.
In general, there are three common cases in which the information given would be enough to construct only one unique isosceles triangle:
Two side lengths and the angle between them (SAS)Two sides and the angle opposite to one of them (SSA)Two angles and any side (AAS)If other information is given, it may or may not be possible to construct a unique isosceles triangle. For example, given only the lengths of two sides, multiple different isosceles triangles can be made, depending on the size of the included angle.
