Which compound inequality has no solution?
= x+5<5 and ²x+¹>1

O 3(x+4) < 12 or 3x + 1 > 10
2x+1
O10<3(x-2) + 1 or
3
O 11 ≤ 5(x + 3) - 9 and 5(x + 3) - 9 <21
<2
ہے
Answer:
The compound inequality that has no solution is 3(x+4) < 12 or 3x + 1 > 10. To solve this inequality, we need to first consider each inequality separately. For the first inequality, 3(x+4) < 12, we can solve for x by dividing both sides of the inequality by 3, like this:
(x+4) < 4
x < 0
This means that the solution to the first inequality is all values of x that are less than 0. For the second inequality, 3x + 1 > 10, we can solve for x by subtracting 1 from both sides of the inequality and then dividing by 3, like this:
3x > 9
x > 3
This means that the solution to the second inequality is all values of x that are greater than 3.
Now that we have the solutions to each inequality, we need to combine them to find the solution to the compound inequality. To do this, we need to consider the "or" that connects the two inequalities. This means that the solution to the compound inequality is the set of values that are either less than 0 or greater than 3. Since there are no values that are both less than 0 and greater than 3, this compound inequality has no solution. The other compound inequalities listed have solutions, so they are not the answer to the question.

Harry's mother makes cakes for a local restaurant. She buys flour and sugar in large amounts. She has 157.86 pounds of flour and 82.69 pounds of sugar. If she uses 15 pounds of flour and 8 pounds of sugar each day, for about how many days will the flour last?
The flour will last for about 11 days.
What is equation ?
The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal. Consider the equation 3x + 5 = 14, where 3x + 5 and 14 are two expressions that are separated by the symbol "equal."
An equals sign is a part of a mathematical expression referred to as an equation. A lot of equations include algebra. In math, algebra is employed when you don't know the precise amount to calculate.
Suppose, the flour will last for x days.
She uses 15 pounds of flour each day.
So, the total amount of flour used in x days 15x pounds.
Given that, she has 157.86 pound of flour.
So, the equation will be
15 x = 157.86
x = 157.86 / 15
= 10.524
≈ 11
Thus, the flour will last for about 11 days.

The speed of light is 299,792 kilometers per second. Zipporah tried converting the speed light to miles per hour using the following equivalencies:
1 km = 0.62 mi
1 min = 60 s
1 hr = 60 min
How fast is the speed of light in miles per hour?
The speed of the light in miles per hour is
66913574.4 miles per hour
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1 hour = 60 minutes
We have,
1 km = 0.62 mi
1 min = 60 s
1 hr = 60 min
Speed of light = 299,792 km per second
This can be written as,
1 km = 0.62 miles
299792 km = 299792 x 0.62 miles
299792 km = 185871.04 miles
1 hour = 60 minute
1 hour = 360 seconds
1/360 hour = 1 second
1 second = 1/360 hour
Now,
= 299792 km / 1 second
= 185871.04 miles / 1/360 hour
= 185871..04 x 360 miles per hour
= 66913574.4 miles per hour

The paragraph proof that is written to prove that if PQ=4(x−3)+1, QR=x+10, and x=7, then PQ≅QR is given below.
What is the paragraph proof?The midpoint of a straight line is a point that divides then line into two equal portions.
Therefore to prove that PQ ≅ QR, the required steps are stated below:
A point on a given straight line which divide it into two equal parts is termed midpoint. So that any mathematical expression for the first fraction or part, is the same as that for the second fraction or part.
In the given question, point Q is the midpoint of line PR.
So that:
PR = PQ + QR (Midpoint theorem)
Thus, PQ = QR (Midpoint theorem)
But, PQ=4(x−3)+1,
QR=x+10, and x=7.
Substitute the value of x in both PQ and QR to have;
PQ = 4(x−3)+1 = 4(7 - 3) + 1 = 4*4 + 1PQ = 17

Hue is arranging chairs. She can form 2 rows of a given length with 8 chairs left over, or 8 rows of that same length if she gets 10 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.
The number of chairs that are in that row length is 3.
How to illustrate the equation?Let the chairs in 1 row be x
Let the total chairs be y.
Since Hue can form 2 rows of a given length with 8 chairs left over, this will be:
y = 2x + 8
Also, it can be 8 rows of that same length if she gets 10 more chairs. This will be:
y = 8x - 10
Combine the equations
2x + 8 = 8x - 10
Collect like terms
8x - 2x = 10 + 8
6x = 18
Divide
x = 18 / 6
x = 3

a student and professor both choose a number between 1 and 10, inclusive. what is the probability they choose the same number?
The probability they choose the same number is 0.1 or 1/10.
What is probability?
Mathematical descriptions of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between zero and one represents the likelihood of an event, with 0 roughly denoting impossibility and 1 denoting certainty. It is more likely that an event will occur if its probability is higher. The flip of a fair (impartial) coin serves as a straightforward illustration. Given that the coin is fair, the outcomes "heads" and "tails" are equally likely; therefore, the likelihood of "heads" equals the possibility of "tails"; since no other outcomes seem to be possible, the likelihood of either "heads" as well as "tails" is 1/2 (also known as 0.5 or 50%).
Whichever number the professor picks doesn't matter. The only thing that matters is that the student matches the predetermined number.
That probability is one-tenth(1/10) for any given number.
Hence, the probability they choose the same number is 0.1 or 1/10.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale." One kilometer on the ground is equal to one centimeter on a map with a scale of 1:100,000. There are three primary scale types found on maps: fractional scales, graphic scales, and written or verbal scales.
The link between the map's landscape and the one it shows is expressed using words in a written or verbal scale, for example, one inch equals one mile. To calculate distances and regions on a map, we can utilize the scale. Calculating distance is easy compared to converting scale types. Since we must square the integers, area computations are more difficult.
If d stands for the desired distance, then the percentage...
d/(17.5 cm) = (15 km)/ (2.5 cm)
can be applied to locate it.
Add 17.5 cm to the result to get...
d = (17.5/2.5)·(15 km) = 105 km

Last year, 10,000 children were born and 2,000 people immigrated. 20,000 people died and 5,000 emigrated. It is believed that the island could support up to 50 people per square kilometer.
The current growth rate is ___.
43%
-43%
4.3 %
-4.3%
The current growth rate of the island is given as follows:
-43%.
How to calculate the growth rate?The first step in calculating the growth rate is obtained the increases and the decreases in the population, as follows:
Increases: 10,000 births + 2,000 people immigrating = 12,000.Decreases: 20,000 deaths + 5,000 people emigrating = 25,000.The total change is obtained by the subtraction of the increases by the decreases, as follows:
Total change = 12,000 - 25,000 = -13,000
Then the growth rate, as a percentage, is obtained by the division of the total change of -13,000 by the initial population of 30,000 and then multiplied by 100%, as follows:
-13,000/30,000 x 100% = -43%.
