What’s the answer

Which Of The Following Choices Shows The Proper Use Of The Distributive Property?-2(6x - Y) = -12x +

Answers

Answer 1

Answer:

[tex]-2(6x - y) = -12x +2y[/tex]

Step-by-step explanation:

Required

Which shows distributive property

Distributive property states that:

[tex]a(b + c) = a * b + a * c[/tex]

So, the solution to -2(6x - y) is:

[tex]-2(6x - y)[/tex]

Open bracket

[tex]-2(6x - y) = -2 * 6x -2 *-y[/tex]

[tex]-2(6x - y) = -12x +2y[/tex]

(a) is true

Carmen made $192 for 12 hours of work.
At the same rate, how many hours would she have to work to make $128?

Answers

Answer:

= 12 miles per hour

Step-by-step explanation:

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=  

12 miles

1 hour

=  

12 miles

hour

= 12 miles per hour

Answer:

Which expression represents the distance around the composite figure

A. 6x+2πx
B. 6x +4πx
C. 10x +2πx
D. 10x +4πx​

Answers

Answer:

A)  6x + 2πx

Step-by-step explanation:

left side of figure = 4x

top and bottom flat portion of figure = 2x

2 semi-circles with radius of x is equal to 1 full circle with diameter = 2xπ

distance around = 4x + 2x + 2xπ or 6x + 2πx

Mark had 3 times as many quarters as nickels. He had $1.60 in all. How many nickels and how many quarters did Mark have? x represents . 3x represents .

Answers

Answer:

x represents nickels = 2

3x represents number of quarters = 6

Step-by-step explanation:

x represents nickels

3x represents number of quarters

We'll multiply each of those times the value of the coin they represent, and make that equal to the total amount of money Mark has to get the value of x

x(0.05) + 3x(0.25) = 1.60

0.05x + 0.75x = 1.60

0.80x = 1.60

x = 2 = number of nickels

So 3x = 6 = number of quarters

Checking the math:

2(0.05) + 6(0.25)= 0.10 + 1.50 = 1.60

Using the Pythagorean theorem: a right triangle has a side that is 24 in and one that is 25in (25 is the diagonal side) what is the length of the third side

Answers

Answer:

Third Side (Perpendicular side) = 7 inch

Step-by-step explanation:

Given:

First side (Base) = 24 inch

Second side (Diagonal/Hypotenuse side) = 25 inch

Find:

Third Side (Perpendicular side)

Computation:

Using Pythagorean theorem;

Perpendicular side = √Hypotenuse side² - Base²

Perpendicular side = √25² - 24²

Perpendicular side = √625 - 576

Perpendicular side = √49

Perpendicular side = 7 inch

Third Side (Perpendicular side) = 7 inch

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

For the true or false, the probability of getting correct is given as,

p = 1/2

There are 570 true or false questions in a quiz. If the pupil guesses for each inquiry. Then the expected value is given as,

E = 570 x (1/2)

E = 285

The mean number of correct answers will be 285.

The difference between two numbers is 7. The sum of twice the larger number and three times the smaller number is 19.

Answers

Answer:

x= 8   y= 1

Step-by-step explanation:

First, you identify your variables:

x= larger number

y= smaller number

Second, you find your equations:

x - y = 7

2x + 3y = 19

Third, (I used the substitution method) you make "y" by itself for the 1st equation.

y = x - 7

2x + 3y = 19

Then, you plug in the 1st equation for "y" in the 2nd equation

2x + 3(x - 7) = 19

Then, you distribute and simplify.

2x + 3x - 21 = 19

5x - 21 = 19

5x = 40

x = 8

Finally, you plug in the variable you found ( x ) into one of the equations and solve,

8 - y = 7

- y = -1

y = 1

Answers

Answer:

  73.6°

Step-by-step explanation:

The whole is the sum of the parts:

  n = 44.5° +29.1°

  n = 73.6°

Answer and Step-by-step explanation:

To find the value of n, we must add the two given angles first.

Why?

We add these two angles together because we are shown that angle n encompasses both angles, meaning that the value of n must be the combination of the angles added together.

29.1 + 44.5 = n

Add.

73.6° = n

The value of n is 73.6°.

Find the area of each figure. Round to the nearest tenth if necessary

Answers

Answer:

b. 869.6 ft²

Step-by-step explanation:

The figure is composed of an equilateral triangle and a trapezoid

Therefore,

Area of the figure = area of the triangle + area of the trapezoid

✔️Area of triangle = ½*a*b*Sin C

Where

a = 22 ft

b = 22 ft

C = 60° (mall angles of an equilateral triangle measures 60°)

Area = ½*22*22*Sin 60°

Area = 209.58 ft²

✔️Area of trapezoid = ½(a + b)h

a = 22 ft

b = 38 ft

h = 22 ft

Area = ½(22 + 38)22

Area = ½(60)22

Area = 960 ft²

✔️Area of the figure = 209.58 + 660 = 869.58 ≈ 869.6 ft²
