Step-by-step explanation:
Five women were giving a friend a baby shower. They decided they would split the cost of everything evenly. The cake cost $25.50 and the gift cost $125.00. They bought 3 packages of plates for $2.75 each and 2 boxes of forks for $1.25 each. How much will each woman spend on the shower?
Answer: $ 32.25 each
Answer:
32.25$ for each woman
Step-by-step explanation:
total cost calculation
cost of plates = 3 * 2.75 =8. 25$
cost of forks = 2*1.25 = 2.50$
total cost = 125+25.50+8.25+2.5=. 161.25$
cost bore by each = 161.25/5 = 32.25$

So first you got to convert all the options into mi/hr then pick the highest one:
Steps:
456.5 mi/hr (dont do anything to this because it is already in mi/hr)
---------------------------------------------------------------------------------------------
0.3 mi/s (this one you got to multipy 0.3 by 3600 to find the mi/hr. the reason being is that there are 30 seconds in a minute and 60 minutes in an hour 60 x 60 = 3600)
---------------------------------------------------------------------------------------------
28 mi/hr (dont do anything to this because it is already in mi/hr)
---------------------------------------------------------------------------------------------
28 mi/min (this one you got to multiply 28 by 60 to find the mi/hr. The reason bing is that there are 60 minutes in an hour)
---------------------------------------------------------------------------------------------
Conversons:
456.5 mi/hr
---------------------------------------------------------------------------------------------
1080 mi/hr
---------------------------------------------------------------------------------------------
28 mi/hr
---------------------------------------------------------------------------------------------
1680 mi/hr

Answer:
1680 mi/hr = 28 mi/min

A mother is five times as old as her daughter. In 6 years, the mother will
be three times as old as her daughter. How old is each now?
PLSSS HHEEELLLLLPPP
(i need steps)
helpppp
Answer:
Mom=30 Daughter=6
Step-by-step explanation:
M=5×D
M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
x = daughter's age
so:
5x = 6 + 3x
5x - 3x = 6
2x = 6
x = 6/2
x = 3
now just do the equations to find her age
mother before 6 years: 5 x 3
mother after 6 years: 3 x (3+6)

Using the combination formula, it is found that he has 232 choices.
The order in which the sights are seen is not important, hence the combination formula is used to solve this question.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

If answered best of all the person who gave the answer will get brain thingy.
It’s due today.
Step-by-step explanation:
Data:
In this question, we're given with a line thought which two lines interest on the common point of that line. Thus, one pair of vertically opposite angles are formed here. We are also obtained with many straight lines.
In those, one straight line has been given with three measurements are 64°, 40° and 76° .
To find:
13⟩. Angle SYX
14⟩. Angle XYW
15⟩. Angle WYV
16⟩. Angle SYW
17⟩. Angle TYX
18⟩. Angle VYX
Solution:
First of all we should find all the given measurement angle vertically opposite angles, After that we can easily find the angles the question has said.
We know that the vertically opposite angles are always equal, so
Angle SYT = Angle WYV = 64°
Angle TYU = Angle XYW = 40°
Angle UYV = Angle SYX = 76°
Now,
13⟩. Angle SYX = 76°
14⟩. Angle XYW = 40°
15⟩. Angle WYV = 64°
16⟩. Angle SYW = 76° + 40° = 116°
17⟩. Angle TYX = 64° + 76° = 140°
18⟩. Angle VYX = 64° + 40° = 104°

3. H
4. F
Step-by-step explanation:
1: To get from one point to another, we have to rise up by 2 and move to the right by 1, thus giving a slope of 2. C is the answer choice where m = 2.
2: Apply the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] using any points. [tex]\frac{4-7}{1-0} = \frac{-3}{1} = -3[/tex]. A is the answer choice where m = -3.

Which polynomials are prime? Check all that apply. 2x2 7x 1 5x2 – 10x 5 3x2 8 4x2 – 25 x2 36.
You can use the definition of prime polynomials to find out which polynomial is prime and which is not.
The prime polynomials in the given options are:
Option 1: [tex]2x^2 + 7x + 1[/tex]
Option 3: [tex]3x^2 + 8[/tex]
What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Which of the given polynomials are prime?Option 1: [tex]2x^2 + 7x + 1[/tex]
We have to check it manually. The roots of this equation are
not integer or integer fraction (checked from calculator), and does't factor into smaller integer coefficient polynomials.
(you can check if its getting factored, manually, and most of the times, if it is not prime, it will get factored).
Thus, it is a prime polynomial.
Option 2: [tex]5x^2 - 10x +5[/tex]
We can rewrite it as
[tex]5x^2 -10x + 5\\5x^2 - 5x -5x =5\\5x(x-1) -5(x-1)\\(5x-5)(x-1)[/tex]
Thus, it is possible to write it as product of lower degree polynomial with integer coefficients, thus it is not a prime polynomial.
Option 3: [tex]3x^2 + 8[/tex]
Since 3 is prime number and since given polynomial is quadratic thus lower degree would be only linear, thus, let
[tex](3x+a)(x+b) = 3x^2 + 8\\3x^2 + (a+3b)x + ab = 3x^2 + 8\\a = -3b\\ab = 8\\(-3b)b = 8\\b = \sqrt{-8/3}[/tex]
b is not a real number, so the factorization is not polynomial factorization.
Thus, it is prime polynomial.
Option 4: [tex]4x^2 - 25[/tex]
We can rewrite it as:
[tex](2x)^2 - 5^2= (2x+5)(2x-5)[/tex]
Thus, not a prime polynomial.
Option 5: [tex]x^2 - 36\\[/tex]
We can rewrite it as:
[tex]x^2 - 6^2 = (x-6)(x+6)[/tex]
Thus, not a prime polynomial.
Thus,

So we know that she makes a base of $60 a week and gets $2 extra for every item she sells. First, we set up an equation for how many items she would have to sell to make exactly $300 in a week. 60+2x=300. Now, all we do is replace the equal sign with a ≥ sign because it says at least which means more than or equal to.

Taylor invested $11,000 in an account paying an interest rate of 3.5% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 14 years?
Answer:
$17,805.64
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 3.5/100
r = 0.035 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 11,000.00(1 + 0.035/1)(1)(14)
A = 11,000.00(1 + 0.035)(14)
A = $17,805.64
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $11,000.00 at a rate of 3.5% per year compounded 1 times per year over 14 years is $17,805.64.
After 14 years, Taylor's account would have approximately $19,580 in it, assuming no deposits or withdrawals are made and the interest rate remains constant at 3.5% compounded continuously.
We have,
The formula for continuous compounding is:
A = P[tex]e^{rt}[/tex]
where A is the final amount, P is the principal (initial amount), e is Euler's number (approximately equal to 2.71828), r is the annual interest rate as a decimal, and t is the time in years.
In this case,
P = $11,000, r = 0.035 (3.5% as a decimal), and t = 14 years.
Plugging in these values, we get:
A = 11000 x e^(0.03514)
Using a calculator, we can evaluate this expression to get:
A ≈ $19,579.94
Rounding to the nearest dollar gives:
A ≈ $19,580
Therefore,
After 14 years, Taylor's account would have approximately $19,580 in it, assuming no deposits or withdrawals are made and the interest rate remains constant at 3.5% compounded continuously.
