Answer:

63 dimes

Step-by-step explanation:

Set up a system of equations where d is the number of dimes and q is the number of quarters:

d + q = 106

0.1d + 0.25q = 17.05

Solve by elimination by multiplying the top equation by -0.25 to eliminate q:

-0.25d - 0.25q = -26.5

0.1d + 0.25q = 17.05

Add together and solve for d:

-0.15d = -9.45

d = 63

So, there were 63 dimes in the piggy bank

Chandani purchased some parrots. 20% flew away and 5% died. Of the remaining, 45% were sold. Now 33 parrots remain. How many par
Paha777 [63]

Answer:

80 parrots were purchased.

Step-by-step explanation:

Let the total number of parrots be k.

If 20% (or 20/100 = 1/5) flew away and 5% (5/100 = 1/20) died, the remaining parrots will be k – (¹/₅k + ¹/₂₀k) = k – ¼k = ¾k.

Of the remaining, 45% (or 45/100 = 9/20) were sold, which means the total number of sold parrots will be ¾k × ⁹/₂₀ = ²⁷/₈₀k.

The remaining parrots = ¾k – ²⁷/₈₀k = ³³/₈₀k = 33

k = 33 × ⁸⁰/₃₃ = 80 parrots were purchased.

If a /b = p /q, then (a + b )/b = _______.
USPshnik [31]
\dfrac ab=\dfrac pq\implies b=\dfrac{aq}p

Substituting into the second expression,

\dfrac{a+b}b=\dfrac{a+\dfrac{aq}p}{\dfrac{aq}p}=\dfrac{ap+aq}{aq}=\dfrac{p+q}q

The average cost c (in dollars) to manufacture x T-shirts is given by the function c=5x+410x. Express the number of T-shirts in
nikklg [1K]

Answer:

x = \frac{C}{415} will be the expression.

Step-by-step explanation:

In this question an expression has been given which represents the relation between average cost C and number of T shirts (x) manufactured.

We have to solve this expression for the value of x (number of T-shirts) in terms of C.

C = 5x + 410x

C = 415x

x = \frac{C}{415}

Therefore, x = \frac{C}{415} will be expression showing the number of T-shirts in terms of average cost.
