In a two-step equation, you should take care of multiplication and division before addition and subtraction.

The probability of a passenger choosing chips and soda will be 25%.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

A particular airline offers three free snack options to its passengers: cookies, chips, and crackers.

Along with the snack, passengers are offered two free drink options: soda or water.

Then the probability of a passenger choosing chips and soda will be

P = 0.5 x 0.5

P = 0.25

Then the probability in the percentage will be

P = 0.25 x 100

P = 25%

Answer:

I need help on this to what is it

Answer:

y=10

Step-by-step explanation:

1.7y+37 is 14 less than the value of 9.3y–25

Answer is 10

Answer:

y=10

Step-by-step explanation:

10 x 1.7 = 17

17 + 34 = 51

10 x 9.3 = 93

93 - 25 = 51

Same answer, so y = 10

Answer:

S = 1/2 . x^2 + 11/2 . x + 15

Step-by-step explanation:

- Let S = the area of the shaded region

- From the figure we see that S = 1/2 the area of the rectangle

- The area of the rectangle is (x+5)(x+6) = x^2 + 11x + 30

--> S = 1/2 (x^2 + 11x + 30)

--> S = 1/2 . x^2 + 11/2 . x + 15

Answer:

-4

Step-by-step explanation:

1. Subtract the 5 from both sides

2. Now you have -2x=8. From here you are going to divide -2 from both sides to isolate the x value

3. Once you've done that you will have x=-4

Answer:

C

Let's simplify the answers. Use absolute value.

| -5.1 | = 5.1 - > |5.1| = 5.1

4.7 - > |4.7| = 4.7

| -0.9 | = 0.9 - > |0.9| = 0.9

- |6.7| = -6.7 - > |-6.7| = 6.7

Now, order each from least to greatest.

0.9, 4.7, 5.1, 6.7

Which one is the smallest? 0.9

So, C is correct.

Answer:

dimensions of the phone are 7 inches x 12.44 inches

Step-by-step explanation:

The formula for the aspect ratio of a display device is a proportional relationship between the width and the height of the display.

That is;

Aspect ratio = height/width

Now, we are given;

Aspect ratio = 16:9 or 16/9

Width = 7" = 177.8 mm

Thus;

16/9 = height/177.8

Multiply both sides by 177.8 to give;

Height = (16 × 177.8)/9

Height = 316.089 mm

Converting 316.089 mm to inches gives us 12.44 inches.

Thus, dimensions of the phone are 7 inches x 12.44 inches

Answer:

Number of monthly calls = 475

Step-by-step explanation:

Given:

Plan 1 = $30 per month unlimited calls

Plan 2 = $11 + $0.04(per call)

Find:

Number of monthly calls, plan 1 better than plan 2

Computation:

Plan 1 (Cost) < Plan 2 (Cost)

30 < 11 + 0.04(x)

19 < 0.04(x)

475 < (x)

Number of monthly calls = 475

Answer:

36

Step-by-step explanation:

(4+2)²

4+2=6

6²=36

Answer:

36

Step-by-step explanation:

So we have the expression:

[tex](4+2)^2[/tex]

Order of operations says: 1) Parentheses, 2) Exponents, 3) Multiplication/Division and 4) Addition/Subtraction.

So, add within the parentheses first:

[tex](4+2)^2\\=(6)^2[/tex]

Now square:

[tex]=36[/tex]

So our answer is 36.

Also, note that you apparently used the distribute property. The distribute property does not work with addition and exponents:

[tex](4+2)^2\neq4^2+2^2[/tex]

You cannot do this. This isn't correct. Instead, you must first add and then square.

Answer:

x = 22

Step-by-step explanation:

Let's say that a & b are complementary angles...

Then cos a = sin b

We can also write sin(3x) as ,

[tex] \sin(3x) = \cos(90 - 3x) [/tex]

Substituting the value of sin(3x) in the question ,

[tex] \cos(x + 2) = \cos(90 - 3x) [/tex]

Cancelling cos from both the sides gives us -

[tex]x + 2 = 90 - 3x\\ [/tex]

Solving this eqn , x = 22

Answer:

[tex]Rate = 8640 fl\ oz/hour[/tex]

Step-by-step explanation:

Given

Rate: 9 gallon in every 8 minutes

Required

Express in fluid ounces per hour

Express rate as follows;

[tex]Rate = \frac{9\ gallon}{8\ minutes}[/tex]

1 gallon = 128 fluid ounces;

So:

[tex]Rate = \frac{9 * 128 fl\ oz}{8\ minutes}[/tex]

1 minutes = 1/60 hour;

So:

[tex]Rate = \frac{9 * 128 fl\ oz}{8 * \frac{1}{60} hour}[/tex]

[tex]Rate = \frac{1152 fl\ oz}{ \frac{8}{60} hour}[/tex]

[tex]Rate = 1152\ fl\ oz/ \frac{8}{60}\ hour[/tex]

[tex]Rate = 1152* \frac{60}{8}\ fl\ oz/hour[/tex]

[tex]Rate = \frac{1152*60}{8}\ fl\ oz/hour[/tex]

[tex]Rate = \frac{69120}{8}\ fl\ oz/hour[/tex]

[tex]Rate = 8640 fl\ oz/hour[/tex]

average of three it's a sum of the three divided by 3:

(91 + 89 + x):3 = 95

                ×3         ×3

Answer:

x=3/5

Step-by-step explanation:

3x+5=0

3x=-5

x=-5/3

Answer:

x = 5/3

Step-by-step explanation:

Given equation: 3x-5 = 0

Add both sides by 5, we get

= 3x - 5 + 5 = 0 + 5

= 3x = 5

Divide both sides by 3, we get

3x/3 = 5/3

or, 3x = 5

so, x = 5/3

Answer:

[tex]10d[/tex] dollars

Step-by-step explanation:

[tex]d[/tex] is a variable, which is just a placeholder for an unknown value. Therefore, we can treat [tex]d[/tex] as if it's a number.

If you earn a certain amount of dollars per week, and you work for 10 weeks, then to find how much money you earn, you'd multiply the amount of weeks (10) by the dollars per week right?

Same logic applies for variables.

Since we have [tex]d[/tex] acting as a placeholder for the amount earned per week, then the total amount of money earned in 10 weeks is [tex]10\cdot d[/tex], which can just be represented as [tex]10d[/tex].

Hope this helped!
