1. 50

2. 9

3. 16

4. 14

5. 60

Step-by-step explanation:

To find the area all you have to do is multiply the base x  width using the formula B x W = A where B is the base, W is the width and A is the area.

1. 5 x 10 = 50

2. 3 x 3 = 9

3. 4 x 4 = 16

4. (Is that a 1 or 7?) 2 x 7 = 14

5. (Assuming that is 6) 10 x 6 = 60

Answer:

1 year= $280

Step-by-step explanation:

30% of 400= 0.3 * 400= 120

400-120= 280

after one year the playstation cost 280

30% of 280= 0.3 * 280= 84

280-84= 196

after 2 years it cost $196

multiply the number by 0.3 to get 30% of the total

Answer:

n = 12

Step-by-step explanation:

Remark

The two angles are complementary. That's because the third angle is a right angle.

Solution

4n - 2 + 3n + 8 + 90 = 180    Subtract 90 from both sides.

4n - 2 + 3n + 8 = 180 -90      Combine like terms.

7n + 6 = 90                            Subtract 6 from both sides.

7n = 90 - 6

7n = 84                                   Divide by 7

n = 84/7

n = 12

Answer:

12.5 minutes

Step-by-step explanation:

Given that,

Fernando can run 600 meters  in 5 minutes.

We need to find how many minutes would it take him to run 1500 meters.

ATQ,

600 m = 5 min

1 m = (5/600) min

For 1500 m,

[tex]t=\dfrac{5}{600}\times 1500\\\\t=12.5\ min[/tex]

So, it will take 12.5 minutes to run 1500 m.

Answer:

5; -22

Step-by-step explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.

Given the following data;

Input: 1 2 3 4 n

Output: -10 -13 -16 -19

For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.

To find the value of n;

We can deduce that the input is increasing by a value of 1.

Thus, n = 4 + 1 = 5

For the output;

We can deduce that the output is increasing by a value of -3.

Thus, the next output = -19 + (-3) = -22

The answer is 240 different possible combinations would there be of one of each category

The fundamental counting principle is a rule used to count the total number of possible outcomes in a situation.

It states that if there are n ways of doing something, and m ways of doing another thing after that, then there are n × m n\times m n×m ways to perform both of these actions.

He can choose an appetizer 5 ways.

For each of those 5 ways to choose an appetizer,

he can choose an entree 12 ways.

That's 5*12 = 60 ways he can choose an appetizer and an entree.

For each of those 60 ways to choose an appetizer and an entree,

he can choose a dessert 4 ways.

That's 60*4 = 240 ways he can choose an appetizer, an entree,

and a dessert.

Therefore 240 different possible combinations would there be of one of each category .
