Mrs. Lovejoy makes flower arrangements. She has 36 red carnations, 60 white carnations, and 72 pink carnations. Each arrangement

Marat540 [252]

Answer:

12 arrangements

Step-by-step explanation:

We solve this question using the Greatest Common Factor method.

We are told that:

She has 36 red carnations, 60 white carnations, and 72 pink carnations.

The same number of each item should be in each basket.

The greatest number of baskets is calculated as follows:

Step 1

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

The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Step 2

We Identify the number that is greatest and common amongst 36,60, and 72

This is 12.

Then the greatest common factor is 12

Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

HELP ME DO THIS QUESTION PLEASE

Leni [432]

Answer:

Volume: 864

Surface Area: 684

Step-by-step explanation:

Volume:

$\frac{1}{2}(9 * 16 * 12) = 864$

Surface-Area: (Pretty Self-explanatory)

1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)

2. Base - 16 * 9 = 144

3. Height/Base - 12 * 16 = 192

4. 15 * 16 = 240

192 + 144 + 108 + 240 = 444

The Surface Area is 684.

Mr. Brown owned a house, which he rented for $60 a month. The house was assessed at $9000. In 1975 the rate of taxation was incr

Alexandra [31]

We first calculate the percentage increase on the tax

Old value = 25×9 = 225 ⇒ The value 9 represents the 9 lots of thousands of the house's value
New value = 28×9 = 252

Increase in tax = 252 - 225 =27
Percentage increase = (27÷225) ×100 = 12%

The amount of yearly rent would be then increased by 12%

Monthly rent = $60
Yearly rent = 60×12 = $720
Increase by 12% = 720×1.12 = 806.4 ⇒ The value 1.12 is the multiplier, obtained from 100%+12%=112%=1.12

The monthly rent is 806.4÷12 = $67.20 which is an increase of $7.20 per month

A plane leaves jfk international airport and travels due west at 570 mi/hr. another plane leaves 20 minutes later and travels 22

olga2289 [7]

Distance=speed*time
distance traveled by plane A after 40 minutes:
distance=570×40/60=380 miles

Distance traveled by B after 40 minutes
distance=20/60×585=195 miles

Thus the distance between them will be given using cosine law:
c^2=a^2+b^2-2ab Cos C
thus we shall have:
c^2=380^2+195^2-2*380*195*cos22
c^2=45016.35275
c=212.171 miles
Thus the distance between them after 40 minutes is 212.171 miles
