LenKa [72]

The question supplied is incomplete. The complete question is shown below:

The Gross national product (GNP) is the value of all the goods and services produced in an economy, plus the value of goods and services imported, less the goods and services exported. During the period of 1994-2004, the GNP of Canada grew about 4.8% per year, measured in 2003 dollars. In 1994, the GNP was $5.9 billion. Assuming this rate continues, in what year with the GNP reach $10 billion?

Answer:

2006

Step-by-step explanation:

Every year, the new GNP will become (100 + 4.8)% of that of the previous year. That is 104.8%, and equivalent of 1.048.

Let P(y) be the GNP after a period of y years.

After y years, the equation for calculating A(y) becomes

A(y)=5.9*(1.048)^y

Since A(y) = 10

10=5.9*(1.048)^y

10/5.9 =(1.048)^y

1.695=(1.048)^y

ln⁡(1.695) = ln⁡(1.048)^y

ln⁡(1.695) = y ln⁡1.048

y=ln⁡1.695/ln⁡1.048

y=11.26 years

1994 + 12 = 2006

Canada’s GNP will reach $10 billion in the year 2006

the table shows ingredients needed to make 1 batch of fruit salad. Mr. Weakland has enough ingredients to make 2 1/2 batches of

Juli2301 [7.4K]

The number of cups of fruit salad that will be in each container is; 3³/₄ cups of fruit salad

<h3>How to divide fractions?</h3>

We are given the table showing the amount of cups of each ingredient as attached.

From the table we see that;

Amount of cups of Pineapple = 2³/₄

Amount of cups of Strawberries = 2¹/₂

Amount of cups of Bananas = 1¹/₂

Amount of cups of Blueberries = 2¹/₄

Now, converting each of the given fractions to improper fractions gives;

11/4, 5/2, 3/2, 9/2

Summing up all the fractions will give us;

11/4 + 5/2 + 3/2 + 9/2

(1/4)(11 + 10 + 6 + 18) = 45/4

Now, since this total amount will be divided by 3, we will have;

45/4 ÷ 3

= 45/4 * 1/3

= 15/4 = 3³/₄ cups of fruit salad

Substitute x = 5 into the expression (-2)x + 6. Do you get -4? Substitute x = -1 into the expression (-2)x + 6. Do you get - 4 W

8090 [49]

Answer:The first method, by substituting 5 into the expression (-2)x + 6 gives the coreect answer of -4

Step-by-step explanation:

Ist method

Substituting x = 5 into the expression (-2)x + 6, we have

(-2) 5 + 6,

=-10 + 6

=-4

2nd method

Substitute x = -1 into the expression (-2)x + 6,we have

(-2)(-1) + 6

2 +6=10

The first method, by substituting 5 into the expression (-2)x + 6 gives the coreect answer of -4
