Answer:
67 cents
Step-by-step explanation:
2 quarters: one quarter is 25 cents, so two will be 50 cents.
5 cents: Just 5 cents.
1 dime: A dime is 10 cents.
2 cents: 2 cents!
Add everything up: 50 + 5 + 10 +2 = 67 cents!
Answer:
1. C) 2/5 or 4.47 if 2/5 means 2 sqrt(5)
2. sqrt(68)
Step-by-step explanation:
1. using the pythagorean theorem
a^2 + b^2 = c^2
where a = distance AB = 4 b = BC = 2 and c = AC = ?
4^2 + 2^2 = c^2
16 + 4 = c^2
20 = c^2
take the square root of each side
sqrt(20) = c
sqrt(4) * sqrt(5) = c
2sqrt(5) = c
2. using the pythagorean theorem
a^2 + b^2 = c^2
where a = distance AC = 8 b = BC = 2 and c = AB = ?
8^2 + 2^2 = c^2
64 + 4 = c^2
68 = c^2
take the square root of each side
sqrt(68) = c
sqrt(4) * sqrt(17) = c
2sqrt(17) = c
did you forget to put the square root of B
Answer:
6
Step-by-step explanation:
A painter mixes 2 1/2 pints (2.5 pints) of yellow paint with 4 pints of red paint to make a certain shade of orange paint. The ratio of yellow paint to red paint is 2.5:4. In order to find the pints of yellow paint needed to be mixed with 10 pints of red paint, we will use conversion fractions.
10 red pints × (2.5 yellow pints/ 4 red pints) ≈ 6 pints (we round off to 1 significant figure)

Answer:
(a) cannot be determined
(b) 44 cm^2
(c) 87 m^2
(d) 180 m^2
(e) 132 m^2
Step-by-step explanation:
(a) missing a horizontal dimension
__
(b) The difference between the bounding rectangle and the lower-left cutout is ...
(8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2
__
(c) The difference between the bounding rectangle and the center cutout is ...
(13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2
__
(d) The difference between the bounding rectangle and the two cutouts is ...
(20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2
__
(e) The difference between the bounding rectangle and the two cutouts is ...
(14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2
