Answer: We need 2.5 quarts of yellow paint.
Step-by-step explanation:
As per given, The ratio of blue paint to yellow paint is [tex]\frac34: \frac{5}{6}[/tex].
[tex]=3\times6:5\times4\\\\=18:20\\\\ =9:10[/tex]
Total green paint = [tex]4\frac34[/tex] quarts
Quantity of yellow paint required = [tex]\frac{10}{9+10}\times4\frac34[/tex]
[tex]=\frac{10}{19}\times\frac{19}{4}\\=\frac{5}{2}\\=2.5\ $$ quarts$$[/tex]
Hence, We need 2.5 quarts of yellow paint.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Arun sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 128 visitors purchased no costume. 3 visitors purchased exactly one costume. 5 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase exactly one costume as a fraction in simplest form.
Answer:
3/136
Step-by-step explanation:
128 + 3 + 5 = 136
= 3/136 (simplest form)

Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 3,8,15
Answer:
Step-by-step explanation:
Not a triangle, because the leg lengths 8 and 3 add up to 11, not to 15.
The sum of the leg lengths must be greater than the length of the 3rd side for a triangle to exist.
a bag contains 4 red marbles and 3 blue marbles. Another bag contains 7 green marbles and 6 yellow marbles. You randomly pick one marble from each bag. One marble is blue and second marble is yellow.
Answer: 18/91 or ≈ 0.2
Step-by-step explanation:
Bag one: 4 red + 3 blue = 7 total
Bag two: 7 green + 6 yellow = 13 total
probability of picking blue from first bag: 3/7
probability of picking yellow from second bag: 6/13
3/7*6/13 = 18/91 or about 0.2 chance
Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
24 cm
18 cm
(it's not 2262 or 2021.9 I've already tried those)
Answer:
Step-by-step explanation:
1. Find the circumference of the cylinder: C = 2πr
2. Multiply this result by the height of the cylinder: A = 2πr·h
3. To this result add the surface areas (there are two) of the ends of the cylinder: 2πrh + 2πr²
This is the correct general formula for the surface area of a cylinder of radius r and height h. If you want specific numbers, please share the values of r and h.
A parabola has the focus at (4,6) and the directrix of Y equals -6
Answer:
y = (x-4)²
Step-by-step explanation:
vertex (h , k)
h = 4 .... axis of symmetry
k = (6 + -6) / 2 = 0 .... midpoint of focus and directrix
equation of parabola: y = (x-4)² y = (x-h)² + k

Ariana wants to buy a house in a few years. She spends $100 a month on takeout coffee. She spends $200 a month on fast food. What can she do to save money for her house?
Answer:
Hm, if Ariana wants to save money for her house, she should spend less money on fast food a month because if she spending $100 dollars for takeout coffee and spending at the same time a month for fast food. she should eat less fast food and less money for coffee because she would be spending way too much money because F = $200 and C = $100 dollars, so $200 + $100 dollars would be $300 dollars a month. she could still have takeout coffee however, not every month. The fast food needs to be taken out of her diet as well because its the fact its unhealthy and costing her way too much money, she should stop having fast food and not have coffee or the fast food EVERY MONTH, she could have the fast food evert 5 months and her takeout coffee every once a month. hopefully this helps ^^

sin^-1(sin 17°)
Answer:
uhm 0 degrees
Step-by-step explanation:
The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
What is inverse trigonometry?Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The inverse trigonometric expression is given below.
⇒ sin⁻¹(sin 17°)
We know that the value of sin⁻¹(sin θ) is θ.
Then the value of the inverse trigonometric expression will be
⇒ sin⁻¹(sin 17°)
⇒ 17°
Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

If f(x) = x + 1, and g(x) = 2x
Answer:
B. (f-g)(x)=4^x-1-2x+11
(f-g)(x) = (4^x-1+6) - (2x-5)
apply like terms while retaining order of operations
6 - (-5) = 11
4^x - 1 - 2x + 11
Step-by-step explanation:
Answer:
f(g(x)) = 2x + 1
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(2x)
= 2x + 1
If bookshelf A is 6 feet long and bookshelf B is 8 feet long, what is the length of bookshelf C?
A.14
B.12
C.16
D.10
Help me please
Answer:
3.5 feet = 3 feet 6 inches
3 * 12 = 36
36 + 6 = 42 inches long
42 / 5/8 → 42 * 8/5 = 42*8/5
336 / 5 = 67.2

the coordinates of point D are (-10, -3) and the coordinates for point G are (-2, -3). Where is point D in relation to point G?
Answer: Choice C
Point D is 8 units to the left of point G
=================================================
Explanation:
Refer to the diagram below. I've graphed both points on the same xy grid. We can draw a horizontal line through points D and G to form a number line of sorts. Count the number of spaces along this number line to go from G to D. You should count 8 spaces to the left.
Effectively, this is the same as drawing a number line and plotting -10 and -2 on this number line. We only worry about the x coordinates of the two points since the y coordinates are the same (both are y = -3). Note how -10 is eight units to the left of -2 on the number line.
This week only, the local coffee shop is reducing the price of a cup of coffee from $3.00 to $2.28. By what percentage is the price reduced?
Answer:
31.6% decrease
Step-by-step explanation:
percent of change = difference between original and new values divided by the original value
n = % change
n = 0.72/2.28
n = .3157
n = 31.6%

-22.8 = 6n check your solution
Answer:
-3.8=n
Step-by-step explanation:
My goal is to get n all by itself, but its multiplied by 6. If I do the inverse operation (which is division) on both sides I will get -22.8/6=n. Now I can just simply combine the like terms and finalize my answer. 6 * 3=18 but -22.8 is a decimal number so my answer will range from around 3.5-3.9. if I divide -22.8/6 I get -3.8. My final answer is n=-3.8
