A florist has 54 white roses, 72 red roses, and 108 pink roses. If he makes the greatest number possible of identical bouquets u

drek231 [11]

Find the greatest common factor of each flower:

White roses = 54 = 1, 2 , 3, 6, 9, 18, 27, 54

Red roses = 72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Pink roses = 108 = 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

The common factors of all three are: 1, 2, 3, 6, 9, 18.

The greatest common factor is 18, so he can make 18 bouquets.

Divide the total red roses by 18:

72 / 18 = 4

There will be 4 red roses in each bouquet.

Time traveler can take 5 books with him and he has 79 books to choose from how many different ways can the books be selected

AveGali [126]

<u>We are given:</u>

The time-traveller has 79 books, but he can only take 5 books

since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter

Hence, we will use combination

<u>Finding the number of ways:</u>

Since we will use combination, ₇₉C₅

We know that the formula for combination is (n!) / (r!(n-r)!)

₇₉C₅ = 79! / 5!(74!)

₇₉C₅ = 22,537,515

Therefore, the time traveller can choose 5 books in 22,537,515 different ways

They decide to buy a new freezer. They have 100 in savings and 121.50 in their bank account. They see a freezer for 285.99. what

marin [14]

Answer: their bank balance would be

- 64.49

Step-by-step explanation:

They have 100 in savings and 121.50 in their bank account. It means that the total amount that they have to buy the freezer is

100 + 121.5 = 221.5

The cost of the freezer is 285.99. If they buy the freezer, the amount that would be left in their bank account or the bank balance would be

221.5 - 285.99 = - 64.49

The negative value is due to the face that they the cost of the freezer is higher than what they have in total.

The perimeter of an isosceles triangle is 32 inches. If the base is longer than half of the two other equal sides by 2 inches, f

Leona [35]

Answer:

Step-by-step explanation:

Let equal sides of an isosceles triangle = a inches

Base = $\frac{1}{2}a+2$ inches

Perimeter = 32 inches

a + a + $\frac{1}{2}a+2$ = 32

$2a + \frac{1}{2}a+2 = 32\\\\\frac{2a*2}{1*2}+\frac{1}{2}a+2=32\\\\\frac{4a}{2}+\frac{1}{2}a+2=32\\\\\frac{5}{2}a+2 = 32\\\\$

Subtract 2 from both sides

$\frac{5}{2}a=32-2\\\\\frac{5}{2}a=30\\\\a=30*\frac{2}{5}\\\\a=6*2$

a = 12 inches

base = $\frac{1}{2}*12+2$

= 6 + 2

Base = 8 inches
