Answer:
$600
Step-by-step explanation:
1 week = $20
30 weeks = 20 x 30 = $ 600
The saving of 30 weeks would be an amount of 600 dollars.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
George makes $20 doing lawn work for 4 hours each week.
He has been saving this money for 30 weeks
The saving of one week = $20
The saving of 30 weeks = $20 × 30
Apply the multiplication operation to get
The saving of 30 weeks = $600
Alternative method :
According to the given situation, we can write a ratio as
one week : 20 dollars = 30 weeks : x dollars
⇒ 1 / 20 = 30 / x
Apply the cross-multiplication operation,
⇒ 1 × x = 30 × 20
Apply the multiplication operation to get
⇒ x = 600
Hence, the saving of 30 weeks would be an amount of 600 dollars.

(X^3 - 1/2x^2 + x) + (x^2 - x/4 - 5)
I need help figure if this out
Answer:
[tex]x^3+\frac{-x^2-x}{4}+x+x^2-5[/tex]
Step-by-step explanation:
[tex](x^3-(\frac{x}{2})^2 +x) + (x^2-\frac{x}{4} -5)[/tex]
The addition sign between the sets of parentheses means to add the two equations together by combining like terms
There is only one term raised to the 3rd power so that remains the same.
Next you have -1/2x ^2 + x ^2 = 1/2x ^2
Then x + -x/4 = 3/4x
And -5 is the only term with no variable so that remains the same.
Now combine into one line:
X ^3 +1/2x^2 + 3/4x -5

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
6, 8, 32/3...
Find the 6th term.
Answer:
a₆ ≈ 25.284
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
8 ÷ 6 = [tex]\frac{32}{3}[/tex] ÷ 8 = [tex]\frac{4}{3}[/tex]
This indicates the sequence is geometric with nth term
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 6 and r = [tex]\frac{4}{3}[/tex] , then
a₆ = 6 × [tex](\frac{4}{3}) ^{5}[/tex] = 6 × [tex]\frac{1024}{243}[/tex] = [tex]\frac{6(1024)}{243}[/tex] ≈ 25.284 ( to the nearest thousandth )
Step-by-step explanation:
it is a geometric sequence.
the common ratio or factor is 4/3.
I got this by simply trying to get from the 2nd to the 3rd term.
8×x = 32/3
24x = 32
x = 32/24 = 16/12 = 8/6 = 4/3
s1 = 6
s2 = s1 × 4/3 = 6 × 4/3 = 24/3 = 8
s3 = s2 × 4/3 = s1 × 4/3 × 4/3 = 6 × 16/9 = 2 × 16/3 = 32/3
sn = s1 × (4/3)^(n-1)
s6 = 6 × (4/3)⁵ = 6 × 1024/243 = 2 × 1024/81 = 2048/81 =
= 25.284

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 30. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 30.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 30. Now let's solve it.
k2 + k = 30 < Given
3k = 30 < Combine like terms
k = 10 < Divide both sides by 3
We know Kim's sister is 10 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 10 for k and you get 10(2) = 20
Kim's sister is 10 y/o and Kim is 20 y/o

hi hun!
From what I understand, ill explain to the best of my knowledge so u understand!
First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.
I see that:
Flower 1: 6 inches
Flower 2: 10 inches
Flower 3: 14 inches
The proportionality which these flowers are growing at is 4 inches every two weeks.
And I also see:
Week 3
Week 5
Week 7
When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!
And also just by looking at the weeks which are 2 weeks separate if u count them.
Week 3 would be:
6/3=2
Week 5 would be:
10/5=2
Week 7 would be:
14/7=2
so the proportionality is 2! c:

345.00 divided by .072 rounded to nearest tenth
the ans is 0.72, your answer is 479.20
Step-by-step explanation:
The solution to the given decimal division is calculated as: 479.17
How to divide decimal numbers?To divide decimals, we need to convert both numbers to a simple unit and divide to get:
345.00/0.072
We know that 0.072 can be written as:
0.072 = 72 * 10⁻³
345.00 can be written as:
345.00 = 34500 * 10⁻²
Thus, we have:
(34500 * 10⁻²)/(72 * 10⁻³)
= (34500/72) * (10⁻²/10⁻³)
= 479.17 * 10
= 479.17

Here is the algebraic solution:
T is the tens digit
O is the ones digit
T+O = 14
So O = 14 - T <---- this is the first equation
The original number is 10*T + O
If the digits are reversed the original number is increased by 18.
The number if the digits are reversed is:
10*O + T = 10*T + O + 18
10*(14-T) + T = 10*T + (14-T) + 18 <--- substitutes O with 14-T per first equation above in bold
140 - 10T + T = 10T + 14 - T + 18 <--- distributive left side
140 - 9T = 9T + 32
140 = 9T + 9T + 32
140 - 32 = 9T + 9T
108 = 18T
108/18 = T
T= 6
THe tens digit is 6.
The ones digit must be 8.
Reversing 86 - 68 = 18
The original number is 68.

Question
A large male giraffe needs to eat at least 75 pounds of food each day. At each feeding, the giraffe is fed 3 pounds of food. The giraffe has already consumed 24 pounds of food. How many more times x does the giraffe need to be fed? Write your answer as an inequality.
Answer:
How many more times x does the giraffe need to be fed?
a) 17 times
Write your answer as an inequality
Let x represent the number of feedings left.
1/3(75 - 24) ≤ x
= (25 - 8) ≤ x
= 17 ≤ x
Step-by-step explanation:
A large male giraffe needs to eat at least 75 pounds of food each day.
At each feeding, the giraffe is fed 3 pounds of food.
Hence,
3 pounds of food = 1 feeding
75 pounds of food =
= 75/3
= 25 feedings.
That means in a day, the giraffe is fed 25 times.
The giraffe has already consumed 24 pounds of food. How many more times x does the giraffe need to be fed?
3pounds of food = 1 feeding
24 pounds of food =
Cross Multiply
= 24/3
= 8 feedings.
From the calculation here, the cloth has already fed the giraffe 8 times
Hence,
= 25feedings - 8 feedings
= 17 Feedings left.
Hence, the giraffe has 17 Feedings left to go.
Write your answer as an inequality
Let x represent the number of feedings left.
1/3(75 - 24) ≤ x
= (25 - 8) ≤ x
= 17 ≤ x

Decide whether each of the following relations is a function. Explain your answer.
Input Outputs Functions?
(A) States Capitals
(B) States Cities
(C) Families Pets
(D) Families Last names
The functions are option (A) States Capitals and option (D) Families Last names
A function is a rule that determines the relationship between one variable and another. If we have a variable which we input into the relationship and gives a unique value for the other variable, the input value is the independent variable while the output is the dependent variable.
For an expression to be function, we must have a unique value of output for every value of input.
So, for option A, States have a unique capital, so it is a function.For option B, States have many cities, so the output is not unique, so it is not a function.For option C, Families can have many pets, so the output is not unique. So, it is not a function.For option D, Families can have only one last name, so the output is unique. So, it is a function.So, the functions are option (A) States Capitals and option (D) Families Last names

Hi there!
When dividing fractions, we flop over the fraction that we divide by and multiply by it instead. Look what happens:
[tex]\frac{1}{4} :\frac{9}{1} =\frac{1}{4} *\frac{1}{9}[/tex]
Now we multiply the numerator by the numerator and the denominator times the denominator:
[tex]\frac{1}{36}[/tex]
Now we do the same thing with the following fractions:
[tex]\frac{9}{1} :\frac{1}{4} =\frac{9}{1} *\frac{4}{1} =36[/tex]
Therefore, our answers are: [tex]\frac{1}{36}[/tex] and 36.Hope this helps!
