Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5
so $409.5 is your answer
Find the length of arc AB
Answer:
OH HELL NO!
Step-by-step explanation:
Answer:
[tex] m\widehat {AB} = 144\degree [/tex]
[tex]m\widehat {ACB} = 216\degree [/tex]
Step-by-step explanation:
Let the measures of the given arcs be 2x and 3x.
[tex] \because m\widehat {AB} \:\&\: m\widehat {ACB} [/tex] sums up to form a circle.
Therefore,
2x + 3x = 360°
5x = 360°
x = 360°/5
x = 72°
2x = 2*72 = 144°
3x = 3*72° = 216°
[tex] \therefore m\widehat {AB} = 144\degree [/tex]
[tex] \& m\widehat {ACB} = 216\degree [/tex]
Martin has a bag of marbles. He removed one marble at random, recorded the color and then placed it back in the bag. He repeated this process several times and recorded his results in the table. Find the experimental probability of drawing each color.
Red: 12
Blue: 10
Green: 15
Yellow: 13
What are two different ways you could find the experimental probability of the event that Martin does not draw a red marble?
Answer:
38/50 ; or 19/25
Step-by-step explanation:
One way could be that you add all the marbles together to get your total marbles; 12 + 10 + 15 + 13 = 50.
Then you add all the colours expect red; 10 + 15 + 13 = 38.
Which would give me 38/50; which simplifed would be 19/25

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles. Which expression shows how many miles Emilie travels in all?
Given :
Emilie rides her bike x miles before she gets a flat tire.
She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.
To Find :
Which expression shows how many miles Emilie travels in all.
Solution :
We know, total distance covered is given by sum of all the distance she travelled.
Distance covered, D = x + 1/3 + 2 1/2
D = x + 1/3 + 5/2
D = (6x + 2 + 15)/6
D = (6x + 17)/6
Therefore, total distance travelled by Emilie is (6x + 17)/6 .

Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if what we have is a function
For a relation to be a function, the mapping must be one to one or many to one
This mean, for every x there must be one y or for every y, there must can be multiple x
But never is it that there are many y for a single x
Looking at the value 0
on the domain, we can see -2 and 1 as the values
Thus, this is not a function
The given formula can be used to determine the volume (V) of a cylinder.
V= Bh = area of base x height
Which of the following is the best approximation of the volume of the cylinder below?
Step-by-step explanation:
it seems the answer is c. 3514 in3
Approximate value of the volume of cylinder is equals to 3514 in³.
What is volume?"Volume is defined amount of space occupied by any 3 dimensional body. It is useful to represents the capacity of any object ."
Formula used
Area of the base = πr²
Volume of a cylinder = area of the base × height
= πr²h
Value of π = 3.14
According to the question,
Diameter of cylinder = 11 in
Radius (r) = Diameter / 2
= 11 / 2
= 5.5 in
Height (h) = 37 in
Substitute the value in the formula we get,
Volume of cylinder = 3.14 ×(5.5)² × 37
= 3514.445 in³
≈ 3514 in³
Hence, approximate value of the volume of cylinder is equals to 3514 in³.

Chloe works for an estate agent. Her monthly pay is made up of a salary of £1,600 and a bonus of £300 if she sells at least 2 properties. She is also paid 6% of the agency's annual profit at the end of the year. Last year the agency had an income of £436,000 and costs of £380,000. There were 4 months in which Chloe sold 2 or more properties. What was Chloe's total pay last year?
Answer:
22,860
Step-by-step explanation:
she makes 1600 per month x 12 months = 19,200
she sold more than 2 properties during the year so add 300
company profit = 436,000 - 380,000
= 56,000
6% of 56,000 = 3,360
add: 19,200 + 300 + 3360
