Answer:
9(5x - 3) option (c)
Step-by-step explanation:
The question isn't clear as well as incomplete without the options. Since there are no options let's determine the answer of the following mathematical expression:
45x - 27
a) 9(3x - 5)
b) 3(12x + 7)
c) 9(5x - 3)
d) 5(7x + 30)
To determine which option is equivalent to 45x - 27, we would check each option by expanding the bracket. Apply BODMAS (stands for Bracket, Of, Division, Multiplication, Addition and Subtraction) after the expansion. That is multiply before you add or subtract.
a) 9(3x - 5) = 9×3x - 5×9
= 27x - 45
b) 3(12x + 7) = 3×12x + 3×7
= 36x + 21
c) 9(5x - 3) = 9×5x - 9×3
= 45x - 27
d) 5(7x + 30) = 5×7x + 30×5
= 35x + 150
From the expansion, only option C is equal to the given expression: 45x - 27

Anna plans to retire at 70 and hopes to withdraw $30,000 per gear until she’s 95. If money earns 6% compounded annually how much will she need at 70
Answer:
$383,500.68
Step-by-step explanation:
The amount needed is the present value of the $30,000 that Anna will withdraw for 25 years compounded at 6% annually
=pv(rate,nper,pmt,fv)
rate is the annual rate of 6%
nper is the number of years of withdrawal which is 95-70=25
pmt is the amount of annual withdrawal which is $30,000
fv is the amount of withdrawals which is unknown
=pv(6%,25,-30000,0)=$383,500.68
The amount of she required at 70 is $$383,500.68 which gives her the benefit of withdrawing $30,000 per year at retirement

Answer:
B
Step-by-step explanation:
For example let's set up a quadratic equation.
Let's use
f(x) = (x + 10)^2 + 7
The seven is the y intercept so let's ignore that and focus on the ten.
When we graph this we end up getting the picture below. Now, why is the vertex at -10? The reason is the equation starts off with a negative sign.
f(n) = (h - x) + k
So, if x is positive then it will remain negative but still go in positive just because the equation has a subtraction sign in it.
As a result when the equation has + 10, it shows that the x is negative because x = -10 and when you do
h- (-10) it becomes h + 10.

Answer:

Step-by-step explanation:
So the mixed numbers as improper fractions is:

4 1/4 = 17 / 4
1 1/4 = 5 / 4
19 / 3 * 17 / 4 * 5 / 4 = 1615 / 48

Step-by-step explanation:
Let the cost of one small shirt be x
And that of a large shirt be y
From the expression above;
4x + 14y = 210; since the total cost of a small shirt by Wili is;
4 * x and the large shirts 14 * y
Similarly for Jordan we have:
12x + 11y = 110; since the total cost of a small shirt by Jordan is;
12 * x and the large shirts 11 * y
We now have two equations,
So you can solve both equations now using elimination method;
If you multiply all the variables of x and y in the first equation by 3 and then subtract the second equation from it, x would be eliminated remaining y;
Multiplying the first equation we have;
12x + 42y = 630
- 12x + 11y = 110
------------------------------
0. + 31y = 520
You can continue from there

Carol is a pet groomer whose yearly gross pay is $45,000. Her exemptions total $4,000 and the state tax rate is 3.5%. How much does she pay in state taxes each month?
Answer:
$119.58
Step-by-step explanation:
We expect Carol's annual tax bill to be the difference of her pay and exemption, multiplied by the tax rate:
annual tax = ($45,000 -4,000) × 0.035 = $1,435
Then her monthly tax bill will be 1/12 of this:
monthly state tax = $1435/12 = $119.58
Carol pays $119.58 in state taxes each month.

The value of a piece of equipment is decreasing at a rate of 7,5% yearly. If the equipment
was valued at $930 when it was purchased, which function represents the value of the
equipment x years after it was purchased? Explain,
Answer:
y=930 x 075^x
Step-by-step explanation:
y is the price after the amount of years x being plugged into the equation. 930 is what you started with. 7.5 is what is being decreased so divide that by 100 and you get 0.075 plug in the amount of years into x and you have your equation

What is the area of the shape below
Answer:
The answer is 886.
You need to find the area of each specific shape and then add them together.
19 * 11 = 209, which is the area of the rectangle in the middle.
34 * 16 = 544, which is the area of the rectangle on the bottom of all the other shapes.
Now the triangle is a little more complicated. It only gives you the length of both the triangle and the rectangle combined, so first you need to subtract the length of the rectangle.
25 - 11 = 14, which is the length of the triangle.
Next, to find the area of a triangle, you need to multiple the length times the height and then divide it by two. 14 * 19 = 266. Divide 266 by 2 and you get 133.
Now, like I said earlier, add all of these together.
544 + 209 + 133 = 886.

more than Goran. How much does each have?
Answer:
Carmen is $ 27, Henry is $ 80, and Goran is $ 20.
Step-by-step explanation:
be Carmen's money "c", Goran's "g" and Henry's "h"
Now, we organize the equations and we are left with:
c + g + h = 127
h = 4 * g
c = g + 7
replacing in the main one we have:
g + 7 + g + 4 * g = 127
6 * g = 127 - 7
g = 120/6
g = 20
now replacing:
h = 4 * 20 = 80
c = 20 + 7 = 27
therefore, Carmen is $ 27, Henry is $ 80, and Goran is $ 20.

Question:
Some smells are perceived as being more feminine or more masculine. Researchers asked a random sample of 300 American adults to score quantitatively the perceived gender-orientation of lavender. Smaller scores indicate a more feminine scent and larger scores a more masculine scent. In this design, a gender-neutral scent would have a perceived gender-orientation score of 12. The participants gave the scent of lavender an average score of 10.28.
Is this evidence that the scent of lavender is not gender neutral, on average? Select the correct statement of H0, Ha, and the hypotheses parameter in the corresponding test. -
a) Let µ be the mean gender-orientation score for all smells being studied. We test H0: µ=12 versus Ha: µ≠12 ; The alternative is two-sided because we want to test if all of the smells are not gender-neutral.
b) Let µ be the mean gender-orientation score for lavender. We test H0:µ=1.28 versus Ha:µ≠10.28; The alternative is two-sided because we want to test if lavender is not gender-neutral.
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.
d) Let µ be the mean gender-orientation score for lavender. We test H0: µ < 12 versus Ha: ≥ 12 ; The alternative is not two-sided because we want to test if lavender is gender-neutral.
Answer:
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.
Step-by-step explanation:
Here, some smells are perceived to be more feminine while some are more masculine. The researcher picked a sample size of 300 american adults to score quantitatively the perceived gender-orientation of lavender.
We are told that when the score is smaller it indicates a mord feminine scent, when the score is larger it indicates a more masculine scent while a score of 12 indicates a gender neutral scent.
In this case the participants gave lavender a score of 10.28
From the above information we have the following :
Mean, µ = 12
Sample size = 300
Sample mean x' = 10.28
Since the sample mean is less than 12, the null and alternative hypotheses will be:
H0 : µ = 12
Ha : µ ≠ 12
This is a two tailed test because the alternative hypothesis is not gender based, which means lavender could be perceived to be either more feminine or more masculine.
The correct option is option C.
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.
