Answer:

d + q = 20

0.25d + 0.10q = 3.05

Step-by-step explanation:

Given

Coins = 20

Value = $3.05

Required

Determine the equation that represent this

From the question, we have that

d = the number of dimes

q = the number of quarters

This implies that;

d + q = 20

Also;

1 d=\$0.25\ \ and\ \\1 q= \$0.10---------- Standard unit of conversion;

This implies that

0.25d + 0.10q = 3.05

Hence, the equations are:

d + q = 20

0.25d + 0.10q = 3.05

One marketing company assumes a yearly growth in social media followers of 2.5% after implementing their ideas. Their client cur
tatyana61 [14]

Answer:

The number of follower after x years is  40,000(1.025)^{x}

Step-by-step explanation:

Given as :

The number of current followers = p = 40,000

The rate of growth of follower = r = 2.5%

The time period of growth = t = x years

Let The number of follower after x years = A

<u />

<u>Now, According to question</u>

The number of follower after x years = number of current followers × (1+\dfrac{\textrm rate}{100})^{\textrm time}

Or, A = p × (1+\dfrac{\textrm r}{100})^{\textrm t}

Or, A = 40,000 × (1+\dfrac{\textrm 2.5}{100})^{\textrm x}

Or, A = 40,000 × (1.025)^{x}

So, The number of follower after x years = A = 40,000 × (1.025)^{x}

Hence, The number of follower after x years is  40,000(1.025)^{x}  Answer

Rewrite the equation by completing the square.
Dennis_Churaev [7]
Once you complete the square, the simplified version of this equation is

(2x - 1)^2= 0

If you want to solve for x, subtract 1 and divide by 2.

x = 0.5
