Answer:

84% or 21/25

Step-by-step explanation:

1 is 8, 2 is 6, 3 is 9, 4 is 11, 5 is 9, 6 is 7. add the values: We get 50.  

because landing on 1 is an 8/50 chance, not landing on one is a 42/50 chance, which in turn is 84% or 21/25.

Kate's garden measures 15 yards by 12 yards. In order to make a path around it she will need to reduce the size of her garden. T
joja [24]
It should be 91.8 yards. Whenever you lower the dimensions, you'd multiply each factor by 0.7 to get a scale factor of them. After doing so, you'd get the dimensions of 10.5 and 8.4. After finding the area of the whole garden area, it'd be 180 yards. Then using the factored area which is 88.2, you'd subtract 88.2 from 180, leaving you with 91.8, being the area of the path.

The perimeter formula for a rectangle is 2l + 2w, where l is the length and w is the width.
s2008m [1.1K]

Answer:

P = 20x + 6

Step-by-step explanation:

Perimeter formula:

P = 2(l + w)

Given:

l = 8x - 1

w = 2x + 4

Work:

P = 2(l + w)

P = 2(8x - 1 + 2x + 4)

P = 2(10x + 3)

P = 20x + 6

One printing machine-printed 1680 books in 70 hours this week. A second printing machine printed for 50 hours this week but prin
STatiana [176]
I believe it might’ve made 2,400 books, because if you divide 70 from 1680 you get 24, meaning it’s pressing about 24 books per hour, if it’s printing twice that you would multiply 48 by 50 and get 2,400.
