Answer:

7/5

Step-by-step explanation:

Answer:

C. 18

Step-by-step explanation:

Let's say the first number is x so the second will be x+1 and the third will be x+2

x+ x+1+x+2=51

3x+3=51

3x=51-3

3x=48

3x/3=48/3

X=16 this is the first number

The second number will be x+1=16+1=17

The third number will be x+2=16+2=18

So the greatest number will be 18

Answer:

First one : 53/100 and 53%

Step-by-step explanation:

0.53 --> 53/100 --> 53%

Answer:

0.53=53/100=53%

Step-by-step explanation:

The decimal equivalent of the unknown percentage is evaluated by moving the decimal 2 places to the left from its current position.

To convert it to an equivalent fraction replace the % sign with x1/100 and simplify:53*1/100

Divide out the common factor to simplify 53/100

Answer:

-7+x/5

Step-by-step explanation:

Answer:

Event 2, Event 3, Event 4, Event 1

Step-by-step explanation:

The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.

The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.

The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A  9 out of 12 times.

The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.

Answer:

[tex]\frac{3}{8}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{13}{24}[/tex]

Step-by-step explanation:

3/8 + 1/6 = ?

Answer:

164 degrees

Step-by-step explanation:

The measure of the individual internal angle in a polygon is;

(n-2)180/n

n = 22

So we have;

(22-2)180/22

= (20 * 180)/22

= 163.64 degrees

To the nearest whole number, this is 164

Think it is the 8 ticket deal cuz it has more but for me it really depends on what I am going to buy them for.

Given:

$184500 are to be divided between 2 people.

One person has 80% of what the other person has.

To find:

The amount each one receive in $.

Solution:

Let $x be the amount received by first person. Then,

Amount received by the second person = 80% of x

                                                                   = 0.80x

Total amount = Amount received by first person + by second person

                      =[tex]x+0.80x[/tex]

                      =[tex]1.80x[/tex]

Total amount is 184500. So,

[tex]1.80x=184500[/tex]

[tex]x=\dfrac{184500}{1.80}[/tex]

[tex]x=102500[/tex]

So, the amount received by the first person is $102,500.

[tex]0.80x=0.80\times 102500[/tex]

[tex]0.80x=82000[/tex]

So, the amount received by the second person is $82,000.

Answer:

1,970

Step-by-step explanation:

The amount earning Elisa Harrington for July through October were 2,087 1,912 1,876 2,005

The formula for Average amount can be calculated as:.

Sum of Amount/Number of terms

Number of terms = 4

Hence:.Average Amount =

2,087 + 1,912 + 1,876 + 2,005/4

= 7,880/4

= 1,970

Therefore, the average amount Elisa was earning was 1,970

Answer:

19.3%

Step-by-step explanation:

6.50-5.45 = 1.05

1.05/5.45 = 0.192605505

* 100 = 19.27% = 19.3% increase

Answer:

Angle θ would be about 17.1 degrees.

Step-by-step explanation:

To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².

c = √4² + 13²

Square 4 and 13 to get 16 and 169 respectively.

c = √16 + 169

Add 16 and 169 to get 185.

c = √185

Find the square root of 185 (I'll round to the nearest tenth.)

c = 13.60147 ≈ 13.6 units

To find angle β, divide AC by AB and find the inverse sine of that.

β = arcsin(13/13.6)

Divide 13 by 13.6. Round to the nearest thousandth.

β = arcsin(0.955)

β ≈ 1.2723 rad

To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.

β ≈ (1.2723 * 57.2957795)°

β ≈ 72.8974203 ≈ 72.9 degrees

Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

Answer:

  m∠T = 45°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so ...

  (2x +10)° +(3x -9)° +(6x -19)° = 180°

  11x -18 = 180 . . . . . collect terms, divide by °

  11x = 198 . . . . . . . . add 18

  x = 18 . . . . . . . . . . . divide by 11

Then the angle of interest is ...

  m∠T = (3x -9)° = (3·18 -9)°

  m∠T = 45°

_____

The other angles are ...

  m∠S = 46°

  m∠U = 89°

Answer:

2n+3

Step-by-step explanation:

Since the question is asking for "a number" times 2, the first thing that is necessary in any expression is 2n. Next, since there is "3 more", 3 must be added to the 2n. Combining this gives the translation 2n+3.

Answer:

D

Step-by-step explanation:

4+4=8 probability of success

4+4+3=11 total senario

therefore 8/11 is your probability of a success

A box of chocolates contains four milk chocolates, four dark chocolates, and three white chocolates. The probability that it is milk or dark chocolate is 8/11.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The total number of milk chocolate = 4

The total number of dark chocolate = 4

The total number of white chocolate = 3

The total number of milk or dark chocolate = 8

Total number of chocolate a box contains = 11

The probability that it is a milk or dark chocolate = 8/11
