Fernando can run 600 meters
in 5 minutes. At this rate,
how many minutes would it
take him to run 1,500
meters?

Answers

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:

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

What are the values of x and y in the parallelogram?

Answers

9514 1404 393

Answer:

  x = 60

  y = 30

Step-by-step explanation:

Adjacent angles are supplementary.

  (5x -180) +x = 180

  6x = 360 . . . . . . . . . . add 180, collect terms

  x = 60 . . . . . . . . divide by 6

Opposite angles are congruent.

  2y = 60 . . . . . . 2y = x

  y = 30 . . . . . . . .divide by 2

The value of x is 60; the value of y is 30.

3) x=60

6)x=86

9) x=40

Step-by-step explanation:

3) 60+60+x=180

120+x=180

X=180-120

x=60

6) 18+(x-8)+(x-2)=180

18-8-2+x+x=180

8+2x=180

2x=180-8

What is a simplification of an expression?

Usually, simplification involves proceeding with the pending operations in the expression.

Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.

Simplification usually involves making the expression simple and easy to use later.

We have been given an expression;

T= 3x + 4y

when T= 38 and x = 6

38 = 3(6) + 4y

4y = 38 - 18

4y = 20

y = 5

A table of values of a linear function is shown below. Find the output when the input is n . Type your answer in the space provided.
input: 1 2 3 4 n
output: -10 -13 -16 -19 (Blank)

Answers

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

Answer:

5; -22

What is fundamental counting principle ?

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 .

2. In a table ternis match, Adonis scores 2 points for every 3 that Lexus makes. What is Adonis final score if Lexus score is 217?

pls help me.. i dont know what this is.. answer this if u know it pls..​

Answers

Answer:

[tex]5 \ apples = 85.00[/tex]

[tex]Adonis = 144.67[/tex]

Step-by-step explanation:

Solving (a):

[tex]3\ apples = 51.00[/tex]

Required

The cost of 5

Divide through by 3, to get the cost of 1

[tex]1\ apple = 17.00[/tex]

Multiply through by 5, to get the cost of 5

[tex]5 * 1\ apple = 17.00*5[/tex]

[tex]5 \ apples = 85.00[/tex]

Solving (b):

[tex]Adonis : Lexus = 2 : 3[/tex]

[tex]Lexus= 217[/tex]

Required

Find Adonis' final score

Substitute 217 for Lexus

[tex]Adonis : 217 = 2 : 3[/tex]

Express as fraction

[tex]\frac{Adonis}{217} = \frac{2}{3}[/tex]

[tex]Adonis = \frac{2}{3} * 217[/tex]

[tex]Adonis = \frac{2 * 217}{3}[/tex]

[tex]Adonis = \frac{434}{3}[/tex]

[tex]Adonis = 144.67[/tex]
