Answer:
A. Charlie
B. Charlie used 48 more beads than Shaniqua
Step-by-step explanation:
Charlie:
25 necklaces with 96 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 96 × 25
= 2,400 beads
Shaniqua:
28 necklaces with 84 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 84 × 28
= 2,352 beads
A. Charlie used more beads
B. 2,400 beads - 2,352 beads= 48 beads
Charlie used 48 more beads than
Shaniqua

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

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.

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

Is this a function? {(2,2),(-1,5),(5,2),(2,-4)}
The given set of ordered pairs, {(2,2),(-1,5),(5,2),(2,-4)}, is not a function.
When is a Relation a Function?In a function, we have the domain values which are the set of x-values (input values), and the range values which are the set of y-values (output values). Each x-value of a function can only have one corresponding y-value. This implies that for a relation to be considered a function, no two y-values must be related or correspond to exactly one x-value.
Given, {(2,2),(-1,5),(5,2),(2,-4)}, the x-value, 2, is related to two different y-values, 2 and -4.
Therefore, the given set of ordered pairs is not a function.
