C= number of acres of corn
W= number of acres of wheat

total is 180 acres

c+w=180

want to plant 3 times as many corn as wheat

c=3w

substitute 3w for c in other

ctw=180

3w+w=180
4w=180

divide both sides by 4

subtract

c=3w

c=3(45)

c=135

135 acres of corn and 45 acres of wheat

tia_tia [17]

Answer:

p = 10800(0.975)^{t}

Step-by-step explanation:

There was a population of 108000 in a small town in 2002. Since then, the population has decreased at a  rate of 2.5% each year.

Therefore, the population is decreasing at a compound rate of 2.5% each year.

Now, using the formula of compounding we can write if p is the population after t years, then  

p = 10800( 1 - \frac{2.5}{100} )^{t}

⇒ p = 10800(0.975)^{t} (Answer)

Please the question is on the picture
Artyom0805 [142]
The question in the picture is very different from the question before the picture.

Half of 12 is ____
is a different question than
12 is ____ halves

When you say, "Halves of 12, 10, ..." it looks like you're asking the first version.

One of something is 2 halves. That is, the number of halves is exactly two times the number of "somethings." Hopefully, you can multiply each of these numbers by 2.

12*2 = 24
10*2 = 10
13*2 = 26
15*2 = 30
8*2 = 16
5*2 = 10

Omar wrote 3 + ( 4 × 6 ) to represent the phrase "3 more then the product of 4 and 6." Did Omar need to use a grouping symbol? E
valentina_108 [34]
The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction).  This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6).  Because of this, Omar did not need to use a grouping symbol.
