for every 3 hours of ballet practice, Danielle drinks 2 cups of water. How much will she drink during 7.5 hours of practice?
Answer:
5 cups of water
Step-by-step explanation:
well if we take this and turn it into a ratio, we know the base is 3hrs/2cups
so if we want to find 7.5hrs/x then we just multiply the two fractions and see what we get. so 7.5 divided by 3 is equal to 2.5
so we take the amount of water she drinks in 3hrs which is 2cups of water and we multiply that by 2.5 leaving us with Danielle drinking 5 cups of water in 7.5 hours of ballet practice.
hope this helps if it did please leave a like, rate, and give me the brainliest is possible!

Answer:
Step-by-step explanation:
The missing angle and the exterior angle, a, must equal 180 so
a+8x-11=180
a=191-8x
The sum of all inner angles must equal 180 so
191-8x+2x+6+5x=180
-x+197=180
-x=-17
x=17

According to the graph, what is the solution (ordered pair) of this system of equations?
Answers:
(2, -3) and (3, -3)
==================================================
Work Shown:
Since f(x) = -3, we'll replace f(x) with -3 and solve for x
f(x) = x^2 - 5x + 3
-3 = x^2 - 5x + 3 .... f(x) replaced with -3
0 = x^2 - 5x + 3 + 3 ... adding 3 to both sides
0 = x^2 - 5x + 6
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0 .... factor; you can also apply the quadratic formula
x-3=0 or x-2=0
x = 3 or x = 2
So that explains where that '2' comes from when they listed (2, ?)
-------------
To find what replaces the question mark, we will plug x = 2 into the function
f(x) = x^2 - 5x + 3
f(2) = 2^2 - 5(2) + 3
f(2) = 4 - 10 + 3
f(2) = -3
We could have skipped this portion and said that the solution is (2,-3) but plugging x = 2 into the function to get the output y = -3 helps confirm that x = 2 is one of the x solutions.
-------------
Let's do the same for x = 3
f(x) = x^2 - 5x + 3
f(3) = 3^2 - 5(3) + 3
f(3) = 9 - 15 + 3
f(3) = -3
We end up with the same output, so x = 3 is confirmed as well.
The graph below visually helps reinforce these confirmations. Each solution is an intersection between the two curves.

Mr Jones buys a new car for £14 995. By the end of the year the value of the car has gone down by 40%. How much is the car now worth?
Answer:
£8997
Step-by-step explanation:
Given data
Mr Jones buys a new car for £14 995
let us find the value of 40% of £14 995
=40/100* £14 995
= 0.4* £14 995
= £5998
Hence the car will cost
=£14 995- £5998
=£8997
62.5% as a decimal and as a fraction. PLEASE SHOW WORK.
Answer:
62.5 as a decimal would be 0.625
As a fraction it would be 625/1000.
Step-by-step explanation:
To write 0.625 as a fraction you have to write 0.625 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.625 = 0.625/1 = 6.25/10 = 62.5/100 = 625/1000
And finally we have:
0.625 as a fraction equals 625/1000
Answer:
decimal
⇒[tex]\frac{62.5}{100}[/tex]
⇒62.5÷100
⇒62.5
fraction
⇒[tex]\frac{62.5}{100}[/tex]

Triangle QRS is located at Q(‐2, 3), R(6, 3), and S(‐2,‐2). Which of the following classifies triangle QRS?
Answer:
Equiangular Triangle (D)
Step-by-step explanation:
The points connect to make a right angle which has all equal angles.
Answer:
it's isosceles!
Step-by-step explanation:
the points form a right triangle, which eliminates equiangular without even thinking about it since equiangular triangles must have all equal angles, which is impossible with a 90 degree angle since all angles of a triangle add up to 180. Equilateral is also eliminated because the side lengths are not equivalent. Scalene is also eliminated because the two sides adjacent to the 90 degree angle are congruent. This leaves isosceles. It is isosceles because it has two congruent side lengths and two congruent angles.
