Answer:

$133507.33

Step-by-step explanation:

x = number of 6 month periods

y = total money in account

After 10 years:

$y = 300x(1.09)^x$

$y = 300(20)(1.09)^2^0$

$y = 6000(5.60441077)$

$y = 33626.46$

After 18 years:

$y = 33626.46(1.09)^x$

$y = 33626.46(1.09)^1^6$

$y = 33626.46(3.97030588)$

$y = 133507.33$

What is the coefficient of q in the sum of (2/3q-3/4) and(-1/6q-r)?

Harlamova29_29 [7]

Answer:

The coefficient is $\frac{1}{2}$

Step-by-step explanation:

The given sum is

$(\frac{2}{3}q -\frac{3}{4})+(-\frac{1}{6}q-r)$

We can choose to add only the coeffients of $q$ or simplify the whole sum.

$=\frac{2}{3}q -\frac{1}{6}q-\frac{3}{4})-r)$

We collect the LCM for the $q$ terms;

$=\frac{4-1}{6}q-\frac{3}{4})-r)$

This will give us;

$=\frac{3}{6}q-\frac{3}{4})-r)$

Which is the same as

$=\frac{1}{2}q-r-\frac{3}{4}$

The coefficient is $\frac{1}{2}$

]7. A zucchini plant in Darnell’s garden was 13 centimeters tall when it was first planted. Since then, it has grown approximate

Pani-rosa [81]

Let d be the number of days and h be the height

h = 13 + 0.6d

Answer: (a) h = 13 + 0.6d

Given height = 0.208m, find d:

0.208m = 20.8 cm

20.8 = 13 + 0.6d

0.6d = 20.8 - 13 = 7.8

d = 7.8 ÷ 0.6 = 13

Answer: (b) 13 days

Camacho is buying a monster truck. The price of the truck is xx dollars, and he also has to pay a 13\%13% monster truck tax.

Maslowich

Answer:

$1.13x$

Step-by-step explanation:

We have been given that Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. We are asked to find the total amount paid by Camacho for the monster truck.

The total cost of monster truck would be x plus 13% of x.

$\text{The total cost of monster truck}=x+\frac{13}{100}x$

$\text{The total cost of monster truck}=x+0.13x$

$\text{The total cost of monster truck}=1.13x$

Therefore, Camacho paid $1.13x$ dollars in total for the truck.
