There were two trees growing seeds in a backyard. One tree grew at a rate of 1/2 a foot every 2 years. The other grew 4 inches e

denis-greek [22]

Answer:

20 in

Step-by-step explanation:

Tree 1:

Rate of growth = (½ ft/2 yr)

12 yr growth = 12 × (½/2)

= 6/2

= 3 ft

= 36 in

Tree 2:

Rate of growth = (4 in/3yr)

12 yr growth = 12 × (4/3)

= 48/3

= 16 in

Difference:

Tree 1 - Tree 2 = 36 - 16

= 20 in

The trees will differ in height by 20 in.

The Vilas County News earns a profit of $20 per year for each of its 3,000 subscribers. Management projects that the profit per

Mekhanik [1.2K]

Answer:

850

Step-by-step explanation:

Current profit per year = $ 20

Number of subscribers = 3000

For each additional subscriber over 3000, the profit will increase by 1 cent or by $ 0.01. For example, for 3001 (3000 + 1) subscribers, the profit will be $ 20.01 per year. Similarly, for 3002 (3000 + 2) subscribers, the profit will be $20.02 per year and so on.

So, for x additional subscribers over 3000, the profit will increase by 0.01(x). i.e. for (3000 + x) subscribers, the profit will be $(20 + 0.01x)

Since, profit per each subscriber is $(20 + 0.01x), the profit for (3000 + x) subscribers will be:

Total profit = Number of subscribers x Profit per each subscriber

Total profit = (3000 + x)(20 + 0.01x)

We want to calculate how many subscribers will be needed to bring a profit of $109,725. So, we replace Total profit by $109,725. The equation now becomes:

$109725=(3000+x)(20+0.01x)\\\\ 109725=60000+30x+20x+0.01x^{2}\\\\ 0.01x^{2}+50x+60000-109725=0\\\\ 0.01x^{2}+50x-49725=0\\$

Using quadratic formula, we can solve this equation as:

$\\ x=\frac{-50 \pm \sqrt{50^{2}-4(0.01)(-49725)}}{2(0.01)}\\\\ x=\frac{-50 \pm67}{0.02}\\\\ x=\frac{-50-67}{0.02} , x=\frac{-50+67}{0.02}\\\\ x=-5850, x=850$

x = -5850 is not a possible solution as this would make the total number of subscribers to be negative. So we reject this value.

Therefore, the answer to this question is 850. 850 more subscribers are needed to being a total profit of $109,725

Clancy has 423 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 34 of a

Amanda [17]

According to the number of cups, 564 people can be invited to the party.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. Total number of cups of yogurt is 423 cups

2. 1 serving = $\frac{3}{4}$ th of a cup

3. Each guest gets $\frac{3}{4}$ of a cup or 1 serving

4. Find out how many guests can be invited to the party,

Cups : People

$\frac{3}{4}$ : 1

423 : p

5. Cross multiply

$\frac{3}{4}$ p = 423 x 1

3p = 423 x 4

p = $\frac{1692}{3}$

p = 564

Therefore, according to the number of cups, 564 people can be invited to the party.
