Kevin has Oranges and grapefruits in a ratio of 40:18. How many oranges does he have if he has 9 grapefruits?

Answer:

x = 16

y = 70.4

Step-by-step explanation:

Two triangles are similar, so we can use the similarity ratio to so find the variables

(2.8)/(22.4) = (8.8)/y cross multiply expressions

197.12 = (2.8)*y divide both sides by 2.8

70.4 = y

use same operation to find x

(2.8)/(22.4) = x/128 cross multiply expressions

358.4 = (22.4)*x divide both sides by 22.4

16 = x

Answer:

nth term = 1 1/2n -1

Step-by-step explanation:

The arithmetic sequence formula is:

a n = a 1 + ( n – 1 ) d

Where: a n

is the nth term in the sequence

a 1

is the first term in the sequence

n

is the term you are solving for

d

is the common difference for any pair of consecutive numbers in the sequence.

First Term or  

n = 1 :

This is given in the problem.

a 1  =  9

Second Term or  

n = 2 :

Substitute  

2  for  n

in the formula and substitute the values from the problem giving:

a 2 = 9 + ( ( 2 – 1 ) × -2 )

a 2 = 9 + ( 1 × -2 )

a 2 = 9 +-2

a 2 = 7

Fifth Term or  n = 5 :

Substitute      in the formula and substitute the values from the problem giving:

a 5 = 9+ ( ( 5– 1 ) × -2 )

a 5 = 9 + ( 4 × -2 )

a 2 = 9 + -8

a 2 = 1  

Using this same process you should be able to determiner the

Third Term or  n = 3

: and Fourth Term or  n = 4 :

8 is the correct answer ...

Answer:

65

Step-by-step explanation:

find discounted price

675*0.25=168.75

675-168.75=506.25

then add tax

506.25*1.0577=535.46(rounded)

600-535.46=64.54

Parenthesis

Exponent

Multiplication

Division

Addition

Subtraction

(left to right)

4²-(3.1+6.4)+4.5

According to PEMDAS, we will do what is inside the parenthesis.

3.1+6.4 = 9.5

4²-9.5+4.5

Then we do figure out the exponent.

4² =  (4)(4) = 16

16-9.5+4.5

Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.

16-9.5 = 6.5

6.5 + 4.5 = 11

11 is your answer :)

Answer:

w > -0.4

Step-by-step explanation:

Given the inequality expression, w – 0.7 > -1.1:

First, we must isolate the variable, w, by adding 0.7 to both sides of the inequality statement:

w – 0.7 + 0.7  >  –1.1 + 0.7

w > -0.4

Therefore, the correct ray is the empty circle with its ray pointing towards the right (Option 4). This implies that -0.4 is not included as an endpoint in the inequality.

Attached is a screenshot of the number line where it shows where the empty circle is located, along with the direction of the arrow.  

Step-by-step explanation:

I assume it is meant to draw 2 blue balls in a row out of the full pool of balls (no other draws happen before or during this process).

tricky, your teacher.

I think the temptation is to simply say 1/3×1/3 = 1/9.

but is it ?

the probabilty to draw one blue ball out of the complete system (no ball missing) is

x / (6+4+x) = 1/3

x = (6+4+x)/3

3x = 6 + 4 + x = 10 + x

2x = 10

x = 5

so, we have a system of 6 orange, 4 green and 5 blue balls (15 all together) .

the probability at our first pull to draw a blue ball is the indicated 5/15 = 1/3.

but now, for the second ball, we have only 6 orange, 4 green and 4 blue balls in the pool (14 altogether).

and so the probability to draw a blue ball out of this is

4/14 = 2/7.

therefore, the probability to draw 2 blue balls is now the combination

1/3 × 2/7 = 2/21

aha ! so, it is a little bit less than the originally suspected probability of 1/9.

Answer:

6.3

Step-by-step explanation:

1.48 * 2.5= 3.7

10-3.7= 6.3

9514 1404 393

Answer:

  $6.30

Step-by-step explanation:

The cost of the grapes is ...

  (2.5 lb)×($1.48 /lb) = $3.70

After that amount is subtracted from the gift card, the remaining balance is ...

  $10.00 -3.70 = $6.30

$6.30 remains on the gift card.

Using it's concept, it is found that the mean income in Sambala is of $87,571.43.

The mean of a data-set is the sum of all observations in the data-set divided by the number of observations.

In this problem, there are 7 observations: 35000, 46000, 68000, 300000, 57000, 41000 and 66000.

Hence, the mean is:

[tex]M = \frac{35000 + 46000 + 68000 + 300000 + 57000 + 41000 + 66000}{7} = 87571.43[/tex]

The mean income in Sambala is of $87,571.43.
