A gift shop wants to make gift baskets for its regular customers. There are 24 bottles of shampoo, 36 tubes of hand lotion, and 60 bars of soap. The same number of each item should be in each basket. What is the greatest number of baskets that can be made.
Answer:
12 baskets
Step-by-step explanation:
We solve this question using the Greatest Common Factor method.
We are told that:
There are
24 bottles of shampoo
36 tubes of hand lotion
60 bars of soap.
The same number of each item should be in each basket.
The greatest number of baskets is calculated as follows:
Step 1
We find the factors of 24, 36, 60
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Step 2
We Identify the number that is greatest and common amongst 24, 36 and 60
This is 12.
Then the greatest common factor is 12
Therefore, the greatest number of baskets is 12 baskets

Plot the points A(-4,-6), B(-10, -10), C(-3, -8) on the coordinate axes below. State the coordinates of point D such that A, B, C, and D would form a parallelogram. (Plotting point D is optional.)
Check the picture below.
Coordinates of point D of parallelogram = (3 , -4)
What is parallelogram?A parallelogram is quadrilateral in which opposite angles are equal and opposite sides of the quadrilateral are equal and parallel to each other.
The Diagonals in the parallelogram bisect each other.
Given points
A(-4,-6), B(-10, -10), C(-3, -8)
Let the 4th point D = (x , y)
In a parallelogram, diagonals bisect each other.
midpoint of BD = midpoint of AC
If two points are (x₁ , y₁) and (x₂,y₂)
then midpoint = {(x₁+x₂)/2 , (y₁+y₂)/2}
midpoint of AC = {(-4 + -3)/2 , (-6 + -8)/2}
= {-7/2 , -7}
midpoint of BD = {(-10 + x)/2 , (-10 + y)/2}
Now,
midpoint of BD = midpoint of AC
{-7/2 , -7} = {(-10 + x)/2 , (-10 + y)/2}
Comparing both sides
taking x -coordinate
(-10 + x)/2 = -7/2
Multiplying with 2 on both sides
-10 + x = -7
x = 3
taking y -coordinate
(-10 + y)/2 = -7
Multiplying with 2 on both sides
-10 + y = -14
y = -14 + 10
y = -4
Point D (x , y) = (3, -4)
Hence, (3, -4) are the coordinates of point D of parallelogram.

A triangular park ABC has sides 120m, 80m and 50m (see Fig. 12.7). A
gardener Dhania has to put a fence all around it and also plant grass inside. How
much area does she need to plant? Find the cost of fencing it with barbed wire at the
rate of Rs 20 per metre leaving a space 3m wide for a gate on one side.
pls answer ASAP
The fence would cover the perimeter of the triangle.
The perimeter is the sum of the 3 sides:
120 + 80 + 50 = 250 meters.
There will be a 3 meter space for the gate, so subtract 3:
250 - 3 = 247 meters of fence is needed.
Now multiply the amount of fences needed by the price per meter:
247 x 20 = Rs 4,490
A restaurant bill is $69. A customer wants to leave a 10% tip. How much should the tip be?

declan deposits $850 into a savings account that pays 3.4% annual interest compounded quarterly. what will be the balance after 5 years?
Answer:
the answer should be $994.5
The balance after 5 year comes out to be $3552.80
What is compound interest ?Compound interest is the interest on savings that is computed using both the original principal and the interest accrued over time. It will accelerate the growth of a sum more quickly than simple interest, which is only applied to the principal sum.
Here,
The declan deposits $850 into a savings account that pays 3.4% annual interest compounded quarterly.
Thus rate= 3.4% and principle amount = 850
Therefore it is compounded quartely,
The balance after year=
[tex]C=Pe^{rt}[/tex]
[tex]C= 850 e^{3.5(5)}\\\\C= 850 e^{17.5}[/tex]
C = 3552.80
Therefore, the balance after a year comes out to be $3552.80
Therefore the balance comes out to be after compounded annually is
$3552.50

the sum
of the square of two consecutive
odd intergers is
290. Find the integers.
Answer:
11 & 13 or - 13 & - 11
Step-by-step explanation:
Let the integers are a - 1 and a + 1.
Sum of squares = 290
=> (a - 1)² + (a + 1)² = 290
=> a² + 1² - 2a + a² + 1² + 2a = 290
=> 2a² + 2 = 290
=> 2(a² + 1) = 290
=> a² + 1 = 290/2 = 145
=> a² = 145 - 1 = 144
=> a = ± √144 = ± 12
If a = + 12, numbers are
12 - 1 = 11 & 12 + 1 = 13
If a = - 12, numbers are
- 12- 1 = - 13 & - 12 + 1 = - 11
You have been saving nickels, dimes, and quarters in a jar for about a year. You decide to see how much money you've saved up. When you get everything counted it turns out you have 361 total nickels, dimes, and quarters worth a total of $41.45. You think is is odd that you have exactly twice as many dimes as quarters. Find the number of each coin. Number of Nickels: Number of Dimes: Number of Quarters:
Answer:
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
Step-by-step explanation:
Let
x = number of nickels
y = number of dimes
z = number of quarters
Total worth of the coins = $41.45
Total number of coins = 361
x + y + z = 361 (1)
dime = $0.1,
nickel = $0.05
quarter = $0.25
0.05x + 0.1y + 0.25z = 41.45 (2)
twice as many dimes as quarters.
y = 2z
Substitute y = 2z into (1) and (2)
x + 2z + z = 361
0.05x + 0.1(2z) + 0.25z = 41.45
x + 3z = 361
0.05x + 0.2z + 0.25z = 41.45
x + 3z = 361 (3)
0.05x + 0.45z = 41.45 (4)
Multiply (4) by 20
x + 3z = 361 (3)
x + 9z = 829 (5)
Subtract (3) from (5)
9z - 3z = 829 - 361
6z = 468
Divide both sides by 6
z = 468 / 6
= 78
z= 78
Recall,
y = 2z
= 2(78)
= 156
y = 156
Substitute the value of y and z into
x + y + z = 361
x + 156 + 78 = 361
x + 234 = 361
x = 361 - 234
= 127
x= 127
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
