Answer:

Coin 1: Penny

Coin 2: Penny

Coin 3: Dime

Coin 4: Quarter

------

Coin 1: 1

Coin 2: 1

Coin 3: 10

Coin 4: 25

Step-by-step explanation:

Clue 1: 1 + 1 + 10 + 25 = 37, which is an odd number so that works.

Clue 2: 1 + 10 = 11, so that works.

Clue 3: 1 = 1 < 10 < 25 (1 is equal to 1 is less than 10 is less than 25) so that works.

If 3 3/4 lb. of candy cost $20.25, how much would 1 lb. of candy cost.
Jet001 [13]

3 3/4 lb of candy costs $ 20.25

we have been given a mixed fraction with both whole number and fraction

so lets convert it an improper fraction

3 3/4

3 wholes are equivalent to 3*\frac{4}{4} = \frac{12}{4}

then 3 3/4 is - \frac{12}{4} + \frac{3}{4} = \frac{15}{4}

so 15/4 lbs -- $ 20.25

then 1 lb is -- \frac{20.25}{15/4} = \frac{20.25*4}{15} = \frac{81}{15} = 5.4

therefore 1 lb is equal to $ 5.40

A woman standing on a hill sees a flagpole that she knows is 40 ft tall. the angle of depression to the bottom of the pole is 14
NemiM [27]
Let distance form the pole = x  and height of the hill = y ft

now we can set up 2 equayions 
tan 18 = (40-y)/x
tan 14 = y/x

from second equation y = sxtan14  so we have:-
 tan 18  = ( 40 - x tan 14) /  x

x tan 18 = 40 - x tan 14
x(tan 18 + tan 14) = 40

x   = 40 / (tan18 + tan 14)  =  69.66 feet Answer
