Answer:
#2 486
#3 25
#4 25
#5 1,000,000
Step-by-step explanation:
Sequences like this always have some rule that determines the next number, a pattern that needs to be followed. Sometimes the pattern is easy to find, sometimes really hard.
#2 One of the first things to check is the ratio of adjacent numbers. Here we have 2 then 6 then 18 then 54 etc.
The most prominent feature of these numbers is that the next number is always three times bigger than the previous. It's safe to assume that the missing number will be 162 • 3 = 486.
#3 Of course numbers can be arranged in the decreasing order as well. However, that does not change their ratio. In this example, carefully examining, we can see that each number in the sequence is exactly twice smaller than the previous:
800 -> 400 -> 200 -> 100 etc.
Following this pattern, we can say that the next number will be 50 / 2 = 25.
#4 Of course, ratio is not the only way to help us find the pattern. One of the very often used methods is also the difference between adjacent numbers. Let's subtract each adjacent pair:
4 - 1 = 3
9 - 4 =5
16 - 9 = 7
Longer the sequence is, greater are the chances to see the pattern, but from this we could conclude that the difference between adjacent numbers is always an odd number (3, 5, 7). We could say that the next odd number is 9, so the missing number is 16 + 9 = 25
There is another pattern that could be found. This sequence could also represent the sequence of squared numbers:
1^2, 2°2, 3°2, 4^2
In this case, the next number would be 5^2 which is also 25.
#5 Again, we can find a pattern established on the ratio of numbers, but this time with repetitive symbol L. After every L, the number is a thousand times bigger than the previous number:
0.001 -> 1 -> 1000
So, following this pattern, the missing number would be 1000 • 1000 which equals to 1000000 (a million).

A 778 ounces B 1418 ounces C 22 ounces D 2978 ounces
There are 11,375 ounces are still in the bucket ⇒ (not in the choices)
Step-by-step explanation:
An art teacher is cleaning up her room at the end of the week
She combines three jars containing 212 ounces, 825 ounces, and 11110 ounces of blue paint in an empty bucketThis bucket is then used to fill one can with 414 ounces of the paint and another can with 358 ounces of the paintWe need to find how many ounces of blue paint are still in the bucket
∵ The jars have 212 ounces, 825 ounces, and 11110 ounces of blue paint
∵ She combines all of them in an empty bucket
- Add them to find the quantity of the blue paint in the bucket
∴ The bucket contains = 212 + 825 + 11110
∴ The bucket contains = 12,147 ounces
∵ This bucket is then used to fill one can with 414 ounces of
the paint and another can with 358 ounces
- Add them to find the quantity that used from the bucket
∵ She used = 414 + 358 = 772
∴ 772 ounces is used to fill the two cans
To find how many ounces of the blue paint are still in the bucket subtract from the total amount of paint in the bucked the amount used to fill the two cans
∵ The remainder paint in the bucket = 12,147 - 772
∴ The remainder paint in the bucket = 11,375 ounces
There are 11,375 ounces are still in the bucket

On a factory floor, 30 out of every 140 toy robots is defective. What percent is defective?
A. 60%
B. 2.67%
C. 0.6
D. 26.67%
Can you help me? Thanks!
Answer:
[tex]21.43\%[/tex]
Step-by-step explanation:
we know that
To find out the percent of robots which are defective, divided the number of defective robots by the total number of robots and multiply the result by 100
Let
x ----> the number of defective robots
y ----> the total number of robots
p ---> percentage of robots which are defective
so
[tex]p=\frac{x}{y} (100)[/tex]
we have
[tex]x=30\\y=140[/tex]
substitute
[tex]p=\frac{30}{140}(100)[/tex]
[tex]p=21.43\%[/tex]
Ethan needs to save at least $500 to purchase a new dirt bike. So far, he has saved $175. If he hopes to use two-fifths of his next paycheck to cover the remaining amount, how much money must he make in his paycheck
Answer:
$812.5
Step-by-step explanation:
Given: Ethan need to save at least $500.
He has saved so far $175
Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.
Lets assume Ethan´s paycheck amount be "x"
First finding the remaining amount to be covered.
Remaining amount= [tex]\$ 500 - \$ 175= \$ 325[/tex]
∴ The remaining amount to be covered is $325.
As given, Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.
Now, using the inequality to find the amount of paycheck.
⇒ [tex]x\times \frac{2}{5} \geq \$ 325[/tex]
multiplying both side by 5
⇒ [tex]x\times 2\geq 325\times 5[/tex]
divinding both side 2
⇒ [tex]x\geq \frac{1625}{2}[/tex]
∴ [tex]x\geq \$ 812.5[/tex]
Hence, Ethan must make at least $812.5 in his paycheck to cover his remaining anount to buy dirt bike.

What is the solution to the equation? 13 and three-fourths + x = 7 and one-fourth
The solution of the expression of 13 and three-fourths + x = 7 and one-fourth equation is x = [tex]6\frac{1}{2}[/tex]
To solve this equation, we need to find the value of x (unknown variable) in the given equation:
13 and three-fourths + x = 7 and one-fourth
First, we need to convert the mixed numbers to improper fractions.
13 and three-fourths = [tex]13 + \frac{3}{4} = 13\frac{3}{4}[/tex]
7 and one-fourth = [tex]7 + \frac{1}{4} = 7 \frac{1}{4}[/tex]
Now, the equation becomes:
[tex]13\frac{3}{4} + x =7\frac{1}{4}\\ x = 13\frac{3}{4} - 7\frac{1}{4}\\\\x = 6\frac{1}{2}[/tex]
true or false:the points (6,13),(21,33),(99,137)all lie on the-same line. the equation of the line is y=4/3x +5
The answer is true.
Step-by-step explanation:
To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.
Substituting the point [tex](6,13)[/tex] in the equation of the line, we get,
[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\13 &=\frac{4}{3}(6)+5 \\&=4(2)+5 \\&=8+5 \\13 &=13\end{aligned}[/tex]
Thus, the values on both sides are equal. The point [tex](6,13)[/tex] lie on the same line.
Substituting the point [tex](21,33)[/tex] in the equation of the line, we get,
[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\33 &=\frac{4}{3}(21)+5 \\&=4(7)+5 \\&=28+5 \\33 &=33\end{aligned}[/tex]
Thus, the values on both sides are equal. The point [tex](21,33)[/tex] lie on the same line.
Substituting the point [tex](99,137)[/tex] in the equation of the line, we get,
[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\137 &=\frac{4}{3}(99)+5 \\&=4(33)+5 \\&=132+5 \\137 &=137\end{aligned}[/tex]
Thus, the values on both sides are equal. The point [tex](99,137)[/tex] lie on the same line.
Thus, all the three points lie on the same plane.
Hence, the answer is true.
All three points (6 , 13), (21 , 33), and (99 , 137) lie on the line y = [tex]\frac{4}{3}[/tex]x + 5. Thus, the statement is True, all three points make the equation true. Option 3 is the correct answer.
To determine whether the points (6,13), (21,33), and (99,137) all lie on the line y = [tex]\frac{4}{3}[/tex]x + 5, we need to substitute the x-values of each point into the equation and see if the corresponding y-values match.
1. For the point (6,13):
Substitute x = 6 into the equation.
⇒ y = ([tex]\frac{4}{3}[/tex]) × 6 + 5
⇒ y = 8 + 5
⇒ y = 13
Since the y-value matches, the point (6,13) is on the line.
2. For the point (21,33):
Substitute x = 21 into the equation.
⇒ y = ([tex]\frac{4}{3}[/tex]) × 21 + 5
⇒ y = 28 + 5
⇒ y = 33
Since the y-value matches, the point (21,33) is on the line.
3. For the point (99,137):
Substitute x = 99 into the equation.
⇒ y = ([tex]\frac{4}{3}[/tex]) × 99 + 5
⇒ y = 132 + 5
⇒ y = 137
Since the y-value matches, the point (99,137) is on the line.
All three points satisfy the equation y = [tex]\frac{4}{3}[/tex]x + 5. Therefore, the statement is True: all three points make the equation true option (3).
Complete question:
True or False:
The points (6,13), (21,33) and (99,137) all lie on the same line. The equation of the line is y = [tex]\frac{4}{3}[/tex]x + 5.
Select the correct explanation.
False, all three points do not make the equation true.True, all three points are positive.True, all three points make the equation true.False, all three points are positive.a. 12

Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The student is 6 feet tall. What is the height of the tree? Show all work
Answer:
Option D
The height of tree is 20 feet tall
Solution:
From given question,
Shadow of tree = 30 feet
Height of tree = ?
Height of student = 6 feet
Shadow of student = 9 feet
We have to find the height of tree
We can solve the sum by proportion
[tex]\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}[/tex]
This forms a proportion and we can solve the sum by cross multiplying
[tex]\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20[/tex]
Thus height of tree is 20 feet tall
what is the domain of the function in this table
Answer:
B. {1, 2, 3, 4}.
Step-by-step explanation:
The domain is the set of x values.
The domain of the function represented by the given table, with the corresponding values of x and y being (1, 2), (2, 4), (3, 3), and (4, 2), is Option B) {1, 2, 3, 4}.

These x-values are explicitly provided in the table, and they are 1, 2, 3, and 4. Therefore, the domain of the function, based on the data in the table, is {1, 2, 3, 4}.
This means that for this specific function, you can input any of these four values into the function, and there are corresponding y-values for each of them. Any other values not listed in the table, such as decimals or negative numbers, are not part of the domain for this function because they do not have corresponding y-values in the given data.
In summary, the domain of the function represented by the table is the Option B). set {1, 2, 3, 4}, which includes the x-values provided in the table.

Which expression is equivalent to the one in the picture?
Answer:

Step-by-step explanation:
To convert a root to a fraction in the exponent, remember this rule:
[tex]\sqrt[n]{a^{m}}=a^{\frac{m}{n}}[/tex]
The index becomes the denominator in the fraction. (The index is the little number in front of the root, "n".) The original exponent remains in the numerator.
In this question, the index is 4.
The index is applied to every base in the equation under the root. The bases are 16, 'x' and 'y'.
[tex]\sqrt[4]{16x^{15}y^{17}} = (\sqrt[4]{16})(\sqrt[4]{x^{15}})(\sqrt[4]{y^{17}}) = (2)(x^{\frac{15}{4}}})(y^{\frac{17}{4}}) = 2x^{\frac{15}{4}}}y^{\frac{17}{4}}[/tex]
To find the quad root of 16, input this into your calculator. Since 2⁴ = 16, [tex]\sqrt[4]{16}[/tex] = 2.
For the "x" and "y" bases, use the rule for converting roots to exponent fractions. The index, 4, becomes the denominator in each fraction.
[tex]2x^{\frac{15}{4}}y^{\frac{17}{4}}[/tex]
