Percentage is a way to describe a part of a whole. The equation can be used to find the regular price of the helmet,h is 0.7(h+85)=74.90.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As we know that all of the items in the bicycle shop are on sale for 30% off, therefore, the cost of each item will be 70% of the real cost. Now, the total amount was spent is $74.90. Thus, if we represent the helmet by h, and bicycle by b, then
[tex]70\%Helmet + 70\%Bicycle = \$74.90\\\\0.70 h + 0.70B = 74.90[/tex]
Taking 0.7 as the common,
[tex]0.7(h+B)=74.90[/tex]
As we know that the regular price of the bicycle(B) is $85, therefore, the equation can be written as,
[tex]0.7(h+85)=74.90[/tex]
Hence, the equation can be used to find the regular price of the helmet,h is 0.7(h+85)=74.90.

A sales associate earned a commission of $26.40 for sales totaling $220.00.
Which proportion could be used to find the commission amount for sales totaling $515.00?
26.4/220=x/515
x/26.4=220/515
220/x=26.4/515
26.4/220=515/x
Answer:
The first option
Step-by-step explanation:
Hello!
We want to find the correct proportion. 26.40/220 is the correct proportion for the amount earned because the associate earned $26.40 out of $220. The term "out of" is division.
Now, we have to match the format, where the commissions are the numerator, and the total is the denominator.
So we have x in the numerator (the same as 26.40) and 515 in the denominator (the same as 220).
This would be the first option : [tex]\frac{26.40}{220} = \frac{x}{515}[/tex]
Let's use ratios
Let that be x[tex]\\ \rm\rightarrowtail \dfrac{26.40}{220}=\dfrac{x}{515}[/tex]
[tex]\\ \rm\rightarrowtail 0.12=x/515[/tex]
[tex]\\ \rm\rightarrowtail x=515(0.12)[/tex]
[tex]\\ \rm\rightarrowtail x=61.8[/tex]

9) pi/3 = 180 /3 = 60⁰
the other angle = 90-60=30⁰
10) 2pi/9 = 360/9 = 40⁰
the other angle = 90+40=130⁰
11) arc length = 2pi * r * (θ/360)
= 2pi * 16 * (270/360)
= 75.4 km
12)arc length = 2pi * r * (θ/360)
3 * 180/4 = 135⁰
135/360 =0.375
2pi * 6 * 0.375 =14.13 in
13) arc length = 2pi * r * (θ/360)
= 9 *2pi *(255/360) =40.05 mi
14)arc length = 2pi * r * (θ/360)
=23.56 mi
Which choice is a linear function?
Explain
Please Help
Answer:
Option C
Step-by-step explanation:
Given the following question:
Using the process of elimination, we can find the answer:
It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.
It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.
It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.
Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.
Hope this helps.
If you flip a coin and get heads you win $8 but if you flip tails you get nothing. How
much money can you expect to win on average?
Answer:
$4 on average
Step-by-step explanation:
A fair coin has a 50/50 chance of being heads/tails.
You have a 50% chance to get heads and win $8.
If you flip the coin twice then it is likely you get heads once and tails once. So, on average, $8 divided by 2 flips = $4.

Complete the equation so that it has no solution 9(x-4)-5x=blank-30
96.1 i dont know if its right but try it
The complete equation so that is has no solution will be;
The number in blank ≠ 4x - 6
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 9 (x - 4) - 5x = blank - 30
Now,
Let the number in he blank = y
So, We get;
⇒ 9 (x - 4) - 5x = y - 30
⇒ 9x - 36 - 5x = y - 30
⇒ 4x - 36 = y - 30
⇒ 4x = y + 6
⇒ y = 4x - 6
Thus, The complete equation so that is has no solution will be;
The number in blank ≠ 4x - 6

Step-by-step explanation:
i know the answer cuz i did this before.
The pattern is that for every minute four dots are added diagnally. To find how many doths there are at 100 minutes we will multiply 4 x 100 and then add one for the dot e started at. 4 x 100 = 400 + 1 = 401
At 100 minutes there will be 401 dots.

I think it would be 2/8 but I know I probably wrong
Answer:
1/4
Step-by-step explanation:
probability is the number of possible solutions over the number of outcomes, so in this example, you would take the 2 possibilities of getting a red M&M, and pot it over all the possible M&Ms you could get, so it is 2/8, which simplifies to 1/4, so you are correct

Using complementary angles, it is found that the solution to the trigonometric equation is of x = 20.
What are complementary angles?Complementary angles are two angles whose measures add to 90º.
If two angles a and b are complementary, we have that the sine of one is the cosine of other, that is:
[tex]\sin{a} = \cos{b}[/tex]
In this problem, the equation is:
[tex]\sin{(2x)} = \cos{(x + 30)}[/tex]
Hence, they are complementary, which means that:
[tex]2x + x + 30 = 90[/tex]
[tex]3x = 60[/tex]
[tex]x = \frac{60}{3}[/tex]
[tex]x = 20[/tex]
The solution to the trigonometric equation is of x = 20.

a1 = -2 r=-2 Sn=22 Determine the number of terms of n in the series
A series can be an arithmetic series or geometric series
The series is undefined
How to determine the number of terms?The given parameters about the geometric series are:
a1 = -2 --- the first term
r=-2 --- the common ratio
Sn=22 --- the sum of n terms
The sum of n terms of a geometric series is represented as:
[tex]S_n = \frac{a(r^n - 1)}{(r-1)}[/tex]
Substitute known values
[tex]22 = \frac{-2((-2)^n -1)}{(-2-1)}[/tex]
This gives
[tex]22 = \frac{-2((-2)^n -1)}{(-3)}[/tex]
Divide both sides by -2
[tex]-11 = \frac{((-2)^n -1)}{(-3)}[/tex]
Multiply both sides by -3
[tex]33 = (-2)^n -1[/tex]
Add 1 to both sides
[tex](-2)^n = 34[/tex]
Take the natural logarithm of both sides
[tex]n\ln(-2) = \ln(34)[/tex]
Solve for n
[tex]n= \frac{\ln(34)}{\ln(-2) }[/tex]
The above number is a complex number.
Hence, the series is undefined

Answer:
just x = 1 is a root.
Step-by-step explanation:
p(-1) = 5(-1)³ - 2(-1)² + 3(-1) - 6 = -5 - 2 - 3 - 6 = -26
so x= -1 isn't root for p(x)
p(1) = 5(1)³ - 2(1)² + 3(1) - 6= 5 - 2 + 3 - 6= 0
so x = 1 is a root for p(x)
