Ron made 3 pitchers of lemonade sell at a lemonade stand. The cost of making the lemonade is 50 cents per pitcher of lemonade.
He sold each cup of lemonade for 15 cents, and he sold a total of 36 cups of lemonade.
How much money did Ron make selling lemonade after paying out the cost of making the lemonade?
Answers
Answer:
Step-by-step explanation:
cost = 3 pitchers × $0.50/pitcher = $1.50
revenue = 36 cups × $0.15/cup = $5.40
profit = $5.40 - $1.50 = $3.90
A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after
exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)=
-16x² + 64x + 80. What is the maximum height of the rocket?
Answers
Answer:
(2,114)
Step-by-step explanation:
g(x)= -16x² + 64x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 64(2) + 80
-16(4)+128+80
-64+128+80

clownfish and 18 seahorses. What is the
ratio of seahorses to total number of fish?
Answers
Answer:
18 : 26
Step-by-step explanation:
It is very easy, angel fish and clown fish are fish, so once you add them up you get 26. The seahorses are 18 and we are supposed to make them S:F. Therefore you put the seahorses first and the fish second, so you get the answer 18:26

Does anyone know the correct answer for this!?!!
Answers
Answer:

Step-by-step explanation:
Use the vertex form equation first since you are given the vertex (-1,-2) where you have (h,k) so h = -1 and k = -2
y = [tex]a (x - -1)^{2}[/tex] + (-2) so if you simplify we get y = a(x+1)^2 -2
Since we are also given a point we can solve for a so x = 2 and y = 16
16 = a(2+1)^2 - 2
16 = a(3)^2 - 2
18 = 9a
a = 2
Charlotte borrows $9000 to buy a second-hand car. The loan must be repaid
over 5 years at 12% p.a. simple interest. Calculate the
total amount to be repaid
Answers
Answer:
$13,400
Step-by-step explanation:
Simple Interest = principal × rate × time
principal= $9000
Rate= 12/100=0•12
Time=5years
Simple interest =PRT
= 9000× 0•12 × 5
= 5400
Total amount to be paid = 9000 + 5400
= $13400
The population of cats in a town increased by 25% from Year 1 to Year 2. The population of cats in Year 2 is 60.
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but I guess that you want to find the population of the cats in Year 1. This will be represented by x. Therefore,
x + (25% × x) = 60
x + (0.25 × x) = 60
x + 0.25x = 60
1.25x = 60
x = 60/1.25
x = 48
The population of cats in year 1 is 48

14. T = 20 + 1.50d so for 16 deliveries T = 20 + 1.50(16) , T = 44
15. p = 1.25s - 135 so if they sell 109 items (s) there is a profit since the profit starts after the original cost is recovered

If WZ = 23 and XZ = 18, what is YZ?
pls help
Answers
Answer:
YZ = 14
Step-by-step explanation:
We are told that;
WZ = 23 and XZ = 18
Now, ∠X in △XWZ which is a right angle triangle can be gotten using trigonometric ratio.
Thus;
WZ/XZ = tan θ
23/18 = tan θ
tan θ = 1.2778
θ = tan^(-1) 1.2778
θ = 51.95°
Now, the ∠X is 90° in △XWY.
Thus, in △XZY, ∠X = 90 - 51.95 = 38.05°
Again, using trigonometric ratio, we can find YZ.
Thus;
YZ/XZ = tan 38.05°
YZ = XZ tan 38.05°
YZ = 18 × 0.7827
YZ = 14.0886
Approximating to a whole number gives: YZ = 14

Answers
Answer:
25 questions
Step-by-step explanation:
20 questions = 80% If she got 80%, that means she got 20 questions correct.
5 questions = 20% Here, we simply just divide by 4 to give us 20%.
25 questions = 100% The total of the test would of course equal 100%, so we just multiply by 5 to give the total questions.
