The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?
Answer:
3 hours
Step-by-step explanation:
Number of shows : Time taken
= 4 : 2
Today, they will perform 6 shows.
Number of shows : Time taken
= 6 : x
Equate both ratios to find x
4 : 2 = 6 : x
4/2 = 6/x
Cross product
4 * x = 2 * 6
4x = 12
x = 12/4
x = 3 hours
The trainers will spend 3 hours performing shows today
Answer:
3 hours

Your friend used the proportion 40/100 = 80/? To find 40% of 80 and says that the answer is 200. Complete the explanation as to why your friend is incorrect and find the correct answer.
Answer: See explanation
Step-by-step explanation:
My friends calculation is wrong. 40% of 80 is not 200. It is:
= 40% of 80
= 40/100 × 80
= 0.4 × 80
= 32
He should have represented the missing number by x. Therefore,
40/100 = 80/x
Cross multiply
(40 × x) = (80 × 100)
40x = 8000
x = 8000/40
x = 200

Answer:
The slope PV is:
m = -4Step-by-step explanation:
Given
P(2, 4)V(3, 0)Determining the slope of PV
(x₁, y₁) = (2, 4)
(x₂, y₂) = (3, 0)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [0 - 4] / [3 - 2]
= -4 / 1
= -4
Thus, the slope PV is:
m = -4How many different triangles can you make if you are given these three lengths

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
Answer:
31.25 kg of flour is needed to make 50 cakes
Step-by-step explanation:
A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.
Flour needed to make 4 cakes = 2.5 kg
Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg
Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]
= 31.25 kg
So, 31.25 kg of flour is needed to make 50 cakes
