Answer:
8 minutes
Step-by-step explanation:
If it takes 12 birds to eat 12 packets of food in 6 minutes that means it takes .5 minutes for 1 bird to eat 1 packet of food. 6÷12=.5
If there is 9 birds to eat 36 packets you first have to multiply the amount of birds times the rate it takes one to eat one packet. 9×.5=4.5 and with this now you know how many packets of food the group of 9 birds can eat per minute. Finally you divide the amount of packets by the amount of packets of food the group of 9 birds can eat per minute. 36÷4.5=8 And that's how they take 8 minutes to eat the 36 packets of food.

Answer:
10 lol so esay
Step-by-step explanation:
I have 2 solutions:
1. Circumference of a circle:
C = 2 r π
10 = 2 r π
r = 10 / 2π = 5 / π
Area of a circle:
A = r² π = ( 5 / π )² * π = 25 / π² * π = 25 / π ≠ 100

The sum of three consecutive even numbers is 582. What is the 1st number?
Answer:
192
Step-by-step explanation:
Answer: The first number is 192 .
Step-by-step explanation:
Let the three consecutive even numbers
be x , x+2 and x +4 .
Their sum = 582
x + (x+2) + (x+4) = 582
x + x +2 + x +4 = 582
3x + 6 = 582
3x = 582 - 6
3x = 576
x =
x = 192
First number = 192
Second number = 192 + 2 = 194
Third number = 192 + 4 = 196

You invest $2,500 in each of two accounts. Account A earns simple interest at a rate of 2% over 4 years. Account B earns simple interest at a rate of 6% over 18 months. Find the interest earned by each account. How does the interest earned by the two accounts compare? Use paper and pencil. Give an example of two principal amounts and two simple interest rates that would earn equal amounts of interest in one year. Give an example of two principal amounts and two periods of time for which the simple interest earned at 2.42% would be equal
Answer: See explanation
Step-by-step explanation:
You invest $2,500 in each of two accounts. Account A earns simple interest at a rate of 2% over 4 years.
Interest = PRT / 100
= (2500 × 2 × 4) / 100
= 20000 / 100
= $200
Account B earns simple interest at a rate of 6% over 18 months.
Interest = PRT / 100
= (2500 × 6 × 1.5) / 100
= 22500 / 100
= $225
Interest for account B is more than that of account A at a shorter period of time.
An example of two principal amounts and two simple interest rates that would earn equal amounts of interest in one year will be:
A: Principal = $2000
Interest rate = 3%
Simple interest = (2000 × 3 × 1)/100 = $60
B. Principal = $3000
Interest rate = 2%
Simple interest = (3000 × 2 × 1) / 100
= 6000 / 100
= $60

5 small bucket and 2 large bucket of water make 20 liter.three small bucket and 2 large bucket make only 18 liter.how much water each bucket hold?
9514 1404 393
Answer:
small: 1 liter; large: 7.5 liters
Step-by-step explanation:
The difference between the two sets of buckets is 2 small buckets and 2 liters. Hence we know that a small bucket is 1 liter.
Then 5 small buckets contribute 5 liters to the 20-liter total. The remaining 15 liters comes from 2 large buckets, so each of those is 7.5 liters.
Large bucket: 7.5 liters
Small bucket: 1 liter

Neil has partially full cans of white paint. They contain 1/3 gallon,1/5 gallon ,and 1/2 gallon of paint. About how much paint does Neil have in all ?
Answer:
31/30 cans of paint
Step-by-step explanation:
We must find a common denominator to add all of these fractions together. We notice that 3 x 5 x 2 = 30. So 10/30 + 6/30 + 15/30 = 31/30 cans of paint
What is an equation of the line that passes through the point (-2,7) and is perpendicular to the line x-4y=24
Answer:
y = -4x - 1
Step-by-step explanation:
x - 4y = 24
-4y = -x + 24
y = [tex]\frac{1}{4}[/tex]x - 6
m⊥ = -4
y = -4x + b
7 = -4 ( -2 ) + b
7 = 8 + b
b = -1
y = -4x - 1

An ice cream shop offers 3 ice cream flavors and 3 types of syrup,and 2 toppings for sundaes . How many different ways are there to make a sundae with one ice cream flavor, one type of syrup, and one topping.
Given:
Types of ice cream = 3
Types of syrup = 3
Toppings for sundaes = 2
To find:
The number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping.
Solution:
We have,
Total number of ways to select 1 form 3 ice cream flavor = 3 ways
Total number of ways to select 1 form 3 syrup = 3 ways
Total number of ways to select 1 form 2 toppings = 2 ways
Now, the total number of ways is
[tex]\text{Total ways}=3\times 3\times 2[/tex]
[tex]\text{Total ways}=18[/tex]
Therefore, the total number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping is 18.
