Answer:
Answer (A)
Step-by-step explanation:
If the expression is indeed [tex]14\cdot 22x+350[/tex] with x representing the number of minutes after the first minute, then the first term, namely:
[tex]14\cdot 22x[/tex]
represents the 14 members handing out 22 fliers per additional minute. And the second term, namely:
[tex]350[/tex]
represents the number of fliers handed out in the first minute, which can be written as 350=14 x 25, so handed out by 14 members, 25 fliers each.
The above said is reflected in the wording of answer (A)

A street sign company is making street signs in the shape of equilateral triangles. The side length of each sign is 22 inches. What is the exact altitude length so that the company will be able to know what size box to ship them in?
Answer: 11 sqrt3
Well, since this is an equilateral triangle, you know that all of the sides have the same length: 22 inches. If you want to find the altitude (height), you would have to use the Pythagorean theorem: a^2 + b^2 = c^2
This means that the sum of the two legs squared is equal to the hypotenuse of the triangle squared.
We already know that the hypotenuse is 22 inches, so we can plug that in as c.
We also know that to make the triangle a right triangle, we will need to halve the bottom side, getting 11 inches, which we can plug in as b.
Lastly, we need to know a, so that is our variable to solve (the height). Here is the equation:
a^2 + (11^2) = (22^2)
This is equal to:
a^2 + 121 = 484
Now subtract 121 from both sides to get a^2 on its own:
a^2 = 363
Lastly, take the square root of both sides to solve for a:
a = 11 sqrt3
The altitude of an equilateral triangle with a side length of 22 inches is 11√3 inches.
Explanation:The altitude of an equilateral triangle can be found using the formula altitude = (side length * √3) / 2.
In this case, the side length of the street sign is 22 inches. Plugging this value into the formula, we get:
altitude = (22 * √3) / 2.
Simplifying, we have:
altitude = 11√3 inches.
Therefore, the exact altitude length is 11√3 inches.
write the standard form of the equation of the line described. through (3, -2) perp. to y=5x + 4
Since it is perp. to y = 5x +4, the slope would be the negative reciprocal of 5, which is -1/5. In order to find the y-in. you have to plug in the values you already know into y=mx+b.
-2 = -1/5(3) + b
b=-7/5
y = -1/5x -7/5
The equation of the line perpendicular to y = 5x + 4 and passes through the point (3, -2) is y = -1/5x - 7/5.
Explanation:The standard form equation of a line is y = mx + b, where m is the slope and b is the y-intercept. The question provides a line equation y = 5x + 4 and informs that the desired line is perpendicular to it. Two lines are perpendicular if the product of their slopes is -1. Hence, the slope of the perpendicular line will be the negative reciprocal of 5 which is -1/5.
Then to find the y-intercept, we use the point that the line passes through which is (3, -2). Insert these values into the equation:y = mx + b, so -2 = -1/5(3) + b, solve to find b = -7/5.
Therefore, the equation of the line in standard form is y = -1/5x - 7/5.

(-8 + 35) + |-16 + 4| A. 15 B. 31 C. 39 D. 55
Here is your equation:
[tex](-8+35) + |-16+4|[/tex]
Let's start with the equation in | |. ←These signs are used for absolute value. Absolute value is the distance between a number and 0. Absolute value is ALWAYS positive.
Here is the equation in the | |:
[tex]-16 + 4[/tex]
The negative number is greater than the positive number. That means your answer will be negative. When adding a greater negative number and a positive number, you can just subtract the positive number from the negative number and add the negative(-) sign.
[tex]16-4 = 12[/tex]
Add the (-) sign and it becomes:
[tex]12 \rightarrow -12[/tex]
Remember you have to find the absolute value of it, and absolute value is ALWAYS positive.
[tex]|-12| \rightarrow 12[/tex]
Here is your new equation:
[tex](-8+35)+12[/tex]
In the parentheses, the positive number is greater than the negative number. An easier way to do it is to subtract the negative number from the positive number.
[tex]35-8 = 27[/tex]
Here is your new(and last) equation:

One week anil earned $4 per hour. The next week he earned $4.50 per hour. What was the percent increased in his hourly rate?
The percent increase in Anil's hourly wage from $4 to $4.50, find the difference ($0.50), divide it by the original wage ($4), and multiply by 100, resulting in a 12.5% increase.
The student is asking how to calculate the percent increase in Anil's hourly wage from one week to the next. He was earning $4 per hour and then began to earn $4.50 per hour. The percentage increase is found by dividing the change in the quantity (the increase in pay) by the original quantity (the original pay) and then multiplying by 100 to get a percent.
To calculate the percentage increase:
Find the difference in pay: $4.50 - $4 = $0.50.
Divide this difference by the original pay: $0.50 / $4 = 0.125.
Multiply by 100 to get the percentage: 0.125 × 100 = 12.5%.
Therefore, the percent increase in Anil's hourly rate is 12.5%.

What is the probability of a sum of 3 or 6 or 9?
Complete the pattern
5,10,30,60,180,__
Hi!
If the pattern starts off with 5 going to 10, then that would be multiplying by 2. Then, from 10 to 30 would be multiplying by 3. From 30 to 60 would be 2, and 60 to 180 would be 3. So, the pattern is multiply by 2, then multiply by 3, then by 2, then by 3, and so on. So, if we multiply 180 by 2, we get 360, the answer.

the sum of three consecutive even number 282. find the three numbers
The three numbers are 93,94,95
The three consecutive even numbers whose sum evaluates to 282 are 92, 94, and 96
What are consecutive numbers?As the term consecutive implies, the numbers who come one after the other are called consecutive.
In case of consecutive even numbers, those even numbers who are adjacent to each other.
Example: 2,4,6 are consecutive events but 2,6,12 are not as there are events between 2 and 6 and between 6 and 12, so they are not closest to each other.
Let the first even of those three consecutive numbers whose sum is 282 be denoted by [tex]2n[/tex]
Then, we get the rest of the two evens as [tex]2n + 2, 2n+4[/tex]
Since their sum is 282, therefore,
[tex]2n + (2n+2) + (2n+4) = 282\\2n +2n + 2n + 2 + 4 = 282\\6n + 6 = 282\\\\\text{Subtracting 6 from both the sides}\\\\6n = 282 - 6 = 276\\\\\text{Dividing both the sides by 6, we get}\\\\n = \dfrac{276}{6} = 46[/tex]
Thus, the three consecutive evens whose sum is 282 are:
[tex]2n = 2(46) = 92\\2n + 2 = 94\\2n + 4 = 96[/tex]
Therefore, the three consecutive even numbers whose sum evaluates to 282 are 92, 94, and 96

some one help me with problems 1,2,3 plz.thank you !
1. Straight lines are 180 degrees. That means 180-126=x. So, x=54.
You can then use x to find y. 180-54=y. y=126. OR You can use vertical angles to find y. Vertical angles are the same degree. So if y is vertical to the angle with 126 degrees, then y=126.
Either way, you will get x=54 and y=126.
2. You would solve problem 2 the same way as problem 1. I encourage you to try to do it yourself, but here's how you would do it.
180-103=y, so y=77. You can either use vertical angles or x=180-77 to find x. You will end up with x=103.
So y=77 and x=103.
3. Here you would use vertical angles. Remember, vertical angles have the same degree! So 2x+29=5x+20. Then all you have to do is solve it.
You would end up with x=3.

A toll collector on a highway receives $4 for cars and $9 for buses. At the end of a 2-hour period, she collected $188. How many cars and buses passed through the toll booth during that period? List all possible solutions.
One answer is 2 cars and 20 buses
The toll collector collected $188 in a 2-hour period. There are three possible solutions: 44 cars and 12 buses, 35 cars and 18 buses, or 26 cars and 24 buses.
Explanation:Let's assume the number of cars passing through the toll booth is 'x' and the number of buses is 'y'.
We can form the following equations based on the given information:
4x + 9y = 188 (total amount collected)
2x + 2y = 2 (total number of hours)
Now we can solve these equations simultaneously to find the values of 'x' and 'y'.
Using substitution or elimination method, we can find that 'x = 44' and 'y = 12', or 'x = 35' and 'y = 18', or 'x = 26' and 'y = 24'.

As triangles are similar therefore the ratio of their corresponding sides are equal . In this case
9/c = 7.5/d
Cross multiply
9d =7.5 c
Now arrange
d/c = 7.5/9
d/c = 75/90
d/c = 5/6
The value of d/c is 5/6
In order to find this, we need to simply replace the values of the triangles that match up. The d portion would match up with 7.5 and the c portion would match up with the 9. So, we can put them into the equation and simplify.
d/c = 7.5/9
d/c = 5/6
