Billy has $16.30 in dimes and quarters. If he has a total of 88 coins, how many of each type of coin does he have?

Answers

Answer 1

Answer:

38 dimes, 50 quarters

Step-by-step explanation:

Let d = dimes

Let q = quarters

d + q = 88

d = 88 - q

0.10d + 0.25q = 16.30

0.10d + 0.25q = 16.30

0.10(88 - q) + 0.25q = 16.30

8.8 - 0.10q + 0.25q = 16.30

8.8 + 0.15q = 16.30

0.15q = 7.5

q = 50

d = 88 - q

d = 88 - 50

d = 38

By how much would the quantity of labor demanded decrease if a minimum wage hike raised prevailing wages from $8 to $10 an hour and if the elasticity of labor demand were 0.40?

Answers

Answer:

it would decrease by 10%

Step-by-step explanation:

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price  

percentage change in price = ($10 - $8) / $8 = 0.25 x 100 = 25%

0.4 =  percentage change in quantity demanded / 25%

percentage change in quantity demanded = 25% x 0.4 = 10%

Jill cuts a piece of cardboard in the shape of a trapezoid.The area of the is 43.5sp cm. If bases are cm and 8.5cm long,what is the height.

Answers

Answer:

7.25cm

Step-by-step explanation:

Let the complete question be;

Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.

Area of a trapezoid = 1/2(a+b)*h

a and b are the parallel sides (bases)

h is the height

Given

a = 3.5cm

b = 8.5cm

A = 43.5 sq.cm

Required

Height h

Substitute the given values into the expression

Area of a trapezoid = 1/2(a+b)*h

43.5 = 1/2(3.5+8.5)*h

43.5 = 1/2 * 12h

43.5 = 6h

h = 43.5/6

h = 7.25cm

Hence the height is 7.25cm

Order 2.000 D5W IV to infuse over 12 hoursThe drop factor is 15 gtt/. Calculate the rate in gtt / min

Answers

Answer:

42gtt/m

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)

Where, Total fluid in ml = 2,000ml

Drop factor = 15gtt/m

Total hours = 12hours

By putting the following value in the formula, we get

Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)

= 30,000 ÷ 720

= 41.67 or 42gtt/m
