I don’t understand my check of solution for the equation ^4√x+12=15 with x=81 and how it becomes 15 if √81 is 9
Answers
^4√81=3
how you do this is basically its saying is what number do you have to multiple to itself 4 times in order to get 81. which is 3
then 3+12=15, so 15=15 that meaning this statement is true :D

Answer:
m∠TQS = 137°
m∠RQS = 43°
Step-by-step explanation:
It is given that ∠RQT is a straight angle
That means that this angle is 180° and RQT is a straight line
Therefore m∠TQS + m∠RQS = m∠RQT = 180°
Given
m∠TQS = (6x + 20)° and m∠RQS = (2x + 40)°
adding the two angles together will imply
(6x + 20)° + (2x + 40)° = 180°
=> 6x + 20 + 2x + 4 = 180
=> 6x + 2x + 20 + 4 = 180
=> 8x + 24 = 180
=> 8x = 180 - 24= 156
=> x = 156/8 = 19.5
Substitute for x in the angle expressions
m∠TQS = 6x + 20 = 6(19.5) + 20 = 117 + 20 = 137°
m∠RQS 2x + 4 = 2(19.5) + 4 = 39 + 4 = 43°
(or we could subtract m∠TQS from 180 to get 180 - 137 = 43°)
Check if they add up to 180°
137° + 43° is indeed 180°

Given the function f(x)=2.5xsquared+3, find the average rate of change over the interval 0 ≤ x ≤ 4. What does the average rate of change tell you about the function?
Answers
The average rate of change over the interval is 10 and it tells us about the slope
How to determine the average rate of changeThe definition of the function is given as
f(x) = 2.5xsquared + 3
Rewrite the function properly
So, we have the following equation
f(x) = 2.5x² + 3
The interval to calculate the average rate of change is given a
0 ≤ x ≤ 4
This can be represented as
[0, 4]
Further, rewrite as
[a, b] = [0, 4]
Where a = 0 and b = 4
Calculate f(a) and f(b)
So, we have
f(0) = 2.5(0)² + 3 = 3
f(4) = 2.5(4)² + 3 = 43
The average rate of change is then calculated as
Average rate = [f(b) - f(a)]/[b - a]
Substitute the known values in the above equation
So, we have
Average rate = [43 - 3]/[4 - 0]
Evaluate
Average rate = 10
What the average rate tells usThe average rate is the slope of the function
This means that it represents the amount of change in the function with respect to the change in the input variables

How to use inequality to represent a situation?Charlie Brown and Linus are so excited for Halloween that they have planned trips to three different parks.
They are willing to pay no more than $40 to go to all of them.
Jones’ Corn Maze has an entry fee that is $4 less than double the amount of Tomilloso’s Pumpkin Patch entrance fee.
King’s Haunted House has an entry fee that is $2 more than Tomilloso’s Pumpkin Patch.
let
x = amount of Tomilloso’s Pumpkin Patch entrance fee
Therefore, the inequality that represent the situation is as follows;
Jones’ Corn Maze an entry fee = 2x - 4
King’s Haunted House entry fee = 2 + x
Therefore,
2x - 4 + 2 + x + x ≤ 40
4x - 2 ≤ 40
add 2 to both sides of the inequality
4x - 2 + 2 ≤ 40 + 2
4x ≤ 42
divide both sides of the inequality by 4
4x / 4 ≤ 42 / 4
x ≤ 10.5

Answers
The solution of the inequality is k > 8.82
How to solve inequality?The expression is in words so we have to convert it to an inequality to be able to solve for k.
An inequality is an expression that has the following symbols: <, >, ≤ and ≥.
Therefore, the inequality can be solved as follows:
k / - 1.8 < - 4.9
Therefore, let's solve for the variable k.
k / - 1.8 < - 4.9
multiply both sides of the inequality by - 1.8
Hence,
k / - 1.8 (-1.8) < - 4.9 (-1.8)
k / 1 > 8.82

How many permutations can be formed from all of the letters of the word houston?.
Answers
The word "Houston" can have a maximum of 2520 permutations using all it's letters.
As per the question statement, we are provided with a word: HOUSTON.
And we are required to calculate the total number of permutations that can be formed using all the letters of it.
To solve this question, first we will need to determine the number of letters in our concerned word, which in this case is 7, and then number of repeated letters, which is 2, since the letter "O" is repeated once.
Therefore, the total number of permutations that can be formed using all the letters of the word HOUSTON = [(7!)/(2!)]
= (7 * 6 * 5 * 4 * 3)
= 2520

Which steps show how to use distributive property to evaluate 5 x 38
Answers
Answer:
The answer is most definitely A. It is the only answer that reaches the correct value of 190, which is what 5 * 38 equals. However, to put it into perspective...
Step-by-step explanation:
When we use the distributive property we are breaking down something sometimes, and in this case, very simple into a more extended form.
5 * 38 is the same as saying 5(40 - 2). We also know that if we subtract the sum of 5 * 2 from 5 * 40, it will end up the same as 5 * 38 because you are multiplying 5 two times less.
5 * 40 = 200
5 * 2 = 10
200 - 10 = 190
The answer is A

santi and vlado drove together from new york to new orleans. both drove the same amount of time, but santi drove 75% as quickly as vlado. if the drive took a total of 24 hours and new orleans is 1,304 miles from new york, approximately how many miles did santi drive?
Answers
If both Santi and Vlado drove for the same amount of time with Santi driving at 75% of Vlado's average speed, and they covered 1304 miles in 24 hours, then Santi had driven for approximately 559 miles.
As per the question statement, Santi and Vlado drove together from New York to New Orleans. Both of them drove for the same amount of time with Santi driving 75% as quickly as Vlado, and it took them 24 hours to complete the 1304 miles journey.
We are required to calculate the approximate number of miles, that Santi drove during their trip.
Since given that, Both of them drove for the same amount of time and it took them 24 hours to complete the 1304 miles journey, therefore, both Santi and Vlado drove for (24/2) = 12 hours each.
Now, let us consider that Vlado drove at an average speed of "v" miles/hour.
Then, Santi would have driven at a average speed of [(75/100)v] m/h
= (0.75v) m/h
= 0.75V miles/hour
[Since Santi drove 75% as quickly as Vlado]
Now as we know that, [(speed * time) = distance], applying the same formula to the velocities and driving times of Santi and Vlado, we get,
[{(12 * v) + (12 * 0.75v)} = 1304]
Or, [(12v + 9v) = 1304]
Or,(21v = 1304)
Or, v = [(1304/21)]
Or, (v = 62.095 miles/hour)
Or, (v ≈ 62.1 miles/hour)
That is, Vlado drove at an average speed of 62.1 miles per hour,
And, Santi drove at an average speed of (62.1 * 0.75) miles per hour
= (46.575) miles per hour.
Therefore, Santi drove a total of (46.575 * 12) = 558.9 miles ≈ 559 miles,
as he drove at an average speed of 46.575 miles per hour, for 12 hours.

What is a ratio mean?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of the lemons to oranges is 6:8 (or 3:4). (or 4:7).
A ratio can have any number of quantities, such as counts of people or things or measurements of the length, weight, time, etc. Both the numbers must be positive in most situations.
You can specify a ratio by either writing out both of the integers that make it up, "a to b" or "a:b", or by giving just the value of their quotient a/b. Equal quotients correspond to the equal ratios.
A ratio can therefore be thought of as an ordered pair of integers, a fraction with first number in the numerator and the second in the denominator, or as the value represented by this fraction. Ratios of the counts that are expressed in terms of (non-zero) natural numbers are rational numbers and occasionally natural numbers as well. The ratio of the two numbers is a dimensionless number when they are measured using the same unit, which happens frequently. A rate is product of two quantities that are divided by their respective units of measurement.
Given,
A model of a famous statue is [tex]3\frac{1}{2}[/tex] inches tall.
The actual statue is [tex]5\frac{1}{4}[/tex] feet tall
1 feet = 12 inches

How many days until Camryn practices the trumpet and flute again in the same day
Answers
The greatest number of identical packages that Shaquira can make is 2.
Given data:
Shaquira has made 86 chocolate chip cookies and 42 sugar cookies.
Shaquira wants to create identical packages of cookies to sell, and she must use all of the cookies.
To find:
The greatest number of identical packages that Shaquira can make
In order to find the greatest number of packages, we find the HCF of 86 and 42.
Write down this part from the attached image.
Here, 86 = 1 × 2 × 43, 42 = 1 × 2 × 21
Thus HCF = 1 × 2 = 2
So, Shaquira can make 2 identical packages the most.
Each package will have
(86 ÷ 2) = 43 chocolate chips and
(42 ÷ 2) = 21 sugar cookies.
For questions like these you would need to find out the Least Common Multiple, or L.C.M
If Camryn plays the trumpet and the flute today, and they both are in intervals of 11 and 3 days, you would need to find the LCM for 11 and 3.
LCM:
11 = 11, 1
3 = 3, 1
As they both have no common factors, and are prime numbers, multiply 11 x 3 = 33.
So, the least amount of days required for the trumpet and the flute to be played together is 33 days. And the interval between practising them both on the same day is 33 days.
Hence, the number of days until Camryn practices the trumpet and the flute on the same day is 33 days.
