6+2y, since the tree is already 6 feet, it grows 2 feet per year so you add 2 feet to the 6 feet every year

A company placed $500,000 in three different investment plans.
Paha777 [63]

Answer:

B. $200,000

Step-by-step explanation:

Let x be the amount placed at 5.5%

3x is the amount placed at 5%

This leaves the rest for the 4.5 %   500000- x - 3x = 500000-4x

Assuming simple interest

I = PRT where I is interest, P is principle, rate is rate and t  is time

Interest for the 5.5% for 1 year is

I = x * .055 * 1 = .055x

Interest for the 5.% for 1 year is

I = 3x * .05 * 1 = .15x

Interest for the 4.5% for 1 year is

I = 500000-4x * .045 * 1 = 22500 - 0.18 x

Add the interest together to get the income for 1 year

.055x+  .15x+22500 - 0.18 x=25,000

Combine like terms

0.025x+22500=25000

Subtract 22500

.025x =2500

Divide by .025

x =100000  

short term notes is 100000

3*x = 300000 = government bonds

The rest is utility bonds 500000- 100000-300000 = 100000

We want how much more in government bond than utility bond

300000 -100000 = 200000

The table shows the number of cups of granola that a bakery uses for every 10 batches of energy bars.
timofeeve [1]

Answer:

<h2>Mike is correct.</h2><h3>To make 30 batches of Rasisin Nut energy bars, the bakery will use 84 cups of granola.</h3><h3>To make 15 batches of Honey Almond energy bars, the bakery will use 63 cups of granola.</h3>

Step-by-step explanation:

<em>Mike says that the bakery uses more granola to make 30 batches of Raisin Nut energy bars than to make 15 batches of Honey Almond energy bars.</em>

<em />

According to the table, the bakery uses 28 cups of granola for 10 batches of Raisin Nut, and 42 cups of granola for 10 batches of Honey Almond. Then, we multiply

R=28 \times 3 = 84 \ cups\\H=42 \times 1.5 = 63 \ cups

Therefore, the bakery uses more granola to make 30 batches of Raising, than to make 15 batches of Honey Almond. Mike is right.

<em>(Notice that we multiplied Raisin Nut by 3, because it represents 3 tens, and Honey Almond was multiplied by 1.5, which represents 15 batches)</em>
