My favorite songstress gives away 25% of the sales of her signature fragrance collection to her charity. Last month her sales was $ 1,200. How much of her total sales did she donate?
Since she donates 25%, take 25% and multiply it by 1,200
[tex].25 * 1,200 = 300[/tex]
or,
[tex]\frac{1}{4} * 1,200 = 300[/tex]

Which statement is true? A.27/19<11/30 b.17/31>19/14 c.16/26>30/31 d.35/30<22/12
is this true 27/19<11/30
In order to check if a comparison such as this is true, you can use this logical equivalence:
[tex] \dfrac{a}{b} > \dfrac{c}{d} \iff ad > bc,\quad \dfrac{a}{b} < \dfrac{c}{d} \iff ad < bc [/tex]
Anyway, it's not always necessary to make this check. We know that every proper fraction represents a number between 0 and 1, and any improper fraction represents a number greater than 1. So, every proper fraction is less than every improper fraction.
So, the first two options are surely wrong, because they ask for a proper fraction to be more than an improper fraction.
The third option compares two proper fractions, so we actually have to check:
[tex] \dfrac{16}{26}>\dfrac{30}{31} \iff 16 \cdot 31 > 26 \cdot 30 \iff 496 > 780[/tex]
which is false.
Last option:
[tex] \dfrac{35}{30}<\dfrac{22}{12} \iff 35 \cdot 12 < 30 \cdot 22 \iff 420 < 660[/tex]
Which is true.

During the summer, payton and James mow the lawns in their subdivision. On each lawn they spend $3.50 on gas and $1.20 on leaf bags. If they charge $22.00 for each lawn ,how much profit do they make?
Answer:
17.30 dollars
Step-by-step explanation:
Given that Payton and James mow the lawns.
They do this during summer.
The amount they spend are:
Gas cost = 3.50
Leaf bags = 1.20
Add these to get total costs
Total cost = 4.70
Charge they get per lawn = 22.00
Profit = Revenue - cost
Here revenue per lawn = 22 and cost per lawn = 4.70
Hence profit = 22-4.70 = 17.30 dollars.
Answer is they make 17.30 dollars per lawn.

Determine whether the given function is a polynomial function. If it's a polynomial function, state the degree. If not, state the reason why.
k(x) = –3x6 – 0.7x + x3
A. Yes; degree 10
B. No, because some range elements correspond to more than one domain element
C. No, because 0.7 isn't an integer
D. Yes; degree 6
ANSWER
The correct answer is option D.
EXPLANATION
The given function is
[tex]k(x)=-3x^6-0.7x+x^3[/tex]
This a polynomial function. All degrees are greater than or equal to zero.
The coefficient being decimals does not disqualify it from being a polynomial.
The highest degree of this polynomial is 6.
Therefore the correct answer is D

The 6 in 63 represents how many times the value of the 6 in 46?
In 63, 6 is in the tenths place, meaning it represrents the number 60.
In 46, 6 is in the ones place, meaning it represents the number 6.
So, given that, in the first example 6 is x times the value of 6 in the second example:
x = 60 / 6
x = 10
Hope it helped,
BioTeacher101
The value of the digit 6 in the number 63 is 10 times the value of the digit 6 in the number 46.
Explanation:In the number 63, the 6 is in the tens place, meaning it represents 60 (6 tens). In the number 46, the 6 is in the ones place, meaning it simply represents 6 (6 ones). Therefore, the 6 in 63 is 10 times the value of the 6 in 46.

Gayle is saving to buy a bicycle. The bicycle costs $119.90 she has saved 0.7 of what she needs how much has she saved so far?
Let the amount saved by Gayle be = x
Cost of the bicycle = $119.90
Gayle's saving till now = 0.7% of 119.90
[tex]\frac{0.7}{100}\times119.90=x[/tex]
[tex]x=0.83[/tex]
Hence, Gayle has saved $0.83 so far.
Answer:
She has saved $83.93.
Step-by-step explanation:
Gayle is saving to buy a bicycle.
The cost of bicycle = $119.90
She has saved = 0.7 of $119.90
= 0.7 × 119.90
= $83.93
The amount she needs more = 119.90 - 83.93
= $35.97
She has saved $83.93.

Answer: Choice A) (5+a)/(a-1)
Step-by-step explanation:
In the numerator, we originally have 3+x. Replace the x with a+2 and we get 3+x = 3+a+2 = 5+a. So the answer will have a numerator of 5+a.
The denominator in the answer will be x-3 = a+2-3 = a-1
Overall that's how the answer is (5+a)/(a-1)

5 times a number, subtracted from six, is triple the number
Final answer:
The algebraic equation based on the statement '5 times a number, subtracted from six, is triple the number' is 6 - 5x = 3x. Solving for 'x' gives us x = 3/4.
Explanation:
The student's question involves creating an algebraic equation based on a verbal statement. To translate the statement '5 times a number, subtracted from six, is triple the number' into an equation, let's use 'x' to represent the unknown number. The statement can be written as: 6 - 5x = 3x. To solve for 'x', we need to get all terms involving 'x' on one side and constants on the other. Here's how you can do it:
Add 5x to both sides of the equation to get: 6 = 3x + 5x
Combine like terms: 6 = 8x
Divide both sides by 8 to get the value of x: x = 6/8
Simplify the fraction: x = 3/4
Therefore, the number in question is 3/4.

Heidi's mom made flower arrangements for a party. She made 4 times as many rose arrangements as tulip arrangements. Heidi's mom made a total of 40 arrangements. How many flower arrangements of each type did Heidi's mom make?
32 rose arrangements and 8 tulip arrangements
8 times 4 = 32
8 + 32 = 40
Heidi's mom made 8 tulip arrangements and 32 rose arrangements. This was determined by setting up equations based on the given information and solving for the number of each type of arrangement.
With 4 times as many rose arrangements as tulip arrangements. Let's denote the number of tulip arrangements as T and the number of rose arrangements as R. According to the information, R = 4T and R + T = 40.
Substituting R in the second equation gives 4T + T = 40, which simplifies to 5T = 40. Solving for T, we find T = 8. Therefore, the number of tulip arrangements is 8. Substituting T = 8 into the equation R = 4T gives R = 32, meaning that there are 32 rose arrangements. Thus, Heidi's mom made 8 tulip arrangements and 32 rose arrangements for the party.

Find the value of Q in the following system so that the system to the solution is {(x,y) : x-3y=4}
x-3y=4
2x-6y=Q
Here, we are required to find the value of Q in the following system so that the system to the solution is {(x,y) : x-3y=4}
x-3y=4
2x-6y=Q
Therefore, Q = 8.
By comparison between equations: x-3y=4 and 2x - 6y = Q.
We need to multiply equation x - 3y = 4 by 2 so that it somewhat resembles 2x-6y=Q;
Ultimately, we have;
2x - 6y = 8 and 2x - 6y = QTherefore, the two equations now resemble one another and therefore, Q = 8

The value of Q that makes the system have the same solution as {(x, y) : x - 3y = 4} is Q = 8.
To find the value of Q in the given system so that the solution is {(x, y) : x - 3y = 4}, you need to make sure that the second equation, 2x - 6y = Q, is equivalent to the first equation, x - 3y = 4.
This means that the two equations have the same solution.
To do this, we can start by simplifying the second equation to be equivalent to the first one:
2x - 6y = Q
We can simplify this equation by dividing both sides by 2:
x - 3y = Q/2
Now, we want this equation to be the same as the first equation, x - 3y = 4.
To make them equal, we need to have Q/2 equal to 4.
Therefore:
Q/2 = 4
To solve for Q, multiply both sides of the equation by 2:
Q = 2 * 4
Q = 8
