Allen Traveled For 7 Hours At A Constant Rate Of 40 Miles Per Hour. Anna Traveled The Same Distance At

Answers

Answer 1

Here is the correct order of the step:

Identify: Anna's time is the unknown

Strategize : let x = Anna's time

Set up : 7(40) = x(50)

Solve: x = 5.6

Check: 7(40) = 5.6(50)

What is Anna's time?

The first step is to determine the distance Allen travelled:

Distance = average speed x time

40 x 7 = 280 miles  

The second step is to determine the time it took Anna to travel 280 miles.

Time = distance / average speed

280 / 50 = 5.6 hours

O 6x?y and 4x® y5
O 10x®y 15 and 14x®y 15
O 9x4y11 and 12x2y4

Answers

Answer:

The length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]

Option A is correct.

Step-by-step explanation:

We are given: [tex]Area\:of\:rectangle=Length\times Width[/tex]

if [tex]Area = 24x^6y^{15}[/tex]we need to find the length and width of rectangle from options given.

Looking at the options, Option B,C and D are incorrect because multiplying the given lengths and widths, the area is not equal to [tex]24x^6y^{15}[/tex]

Only Option A gives us the result i,e

[tex]Area=2x^5y^8\times 12xy^7\\Area=24x^6y^{15}[/tex]

So, the length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]

Option A is correct.

Answers

Answer:

-54

Step-by-step explanation:

first fill in the numbers

next do the parentheses 17 + 21=38

then find -8×2 which equals -16

then subtract -16 from 38 and get -54

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

⇒ a² - (b + c)

The value of the expression at a = -8, b = 17, and c = 21 will be

⇒ a² - (b + c)

⇒ (-8)² - (17 + 21)

⇒ 64 - 38

⇒ 26

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

question:: 81% of 49 is what?

Answers

Answer:

39.69

Step-by-step explanation:

Make the following equation: 81/100 = x/49. Then, multiple 81 and x by 49. Divide the answer, 3969, by 100, which gives you the answer.

39.69. because percentages are parts of 100, you can change the form of 81% to .81. the ‘of’ in ‘81% of 49 indicates multiplication, so to solve this you do .81 x 49, which equals to 39.69
