13-196/4

13-49

-13

Answer 2

Answer & Step-by-step explanation:

(5 + 1)² - (11 + 3²) ÷ 4

Following the rules of order of operation, the first thing we have to do is the operations in the parentheses ().

(6)² - (11 + 3²) ÷ 4

Next, solve for your exponents.

36 - (11 + 9) ÷ 4

Next, do the operations in the parentheses ().

36 - (20) ÷ 4

Now, divide -20 by 4.

36 - 5

Subtract 5 from 36.

31

So, your final answer to this equation is 31.

what transformations were applied to ABCD to obtain A'B'C'D'?

Answers

Answer:

the answer is C

Step-by-step explanation:

Rotate 90 degrees counterclockwise , the translate three units to the left

Option C is the correct transformation to transform ABCD to A'B'C'D'.

What are rotation and translation?Rotation involves moving an object about a fixed point. Each point on the object describes a circular path with the center, the center of rotation.Translation involves moving an object such that only one of the three cartesian coordinates changes during the transformation.

Rotation

Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.

Vertical Translation

After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.

Horizontal Translation

The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.

Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

During the summer, jody earns 10$ per hour babysitting and 15$ per hour doing yardwork. This week she worked 34 hours and earned 410$. If x represents the number of hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation?

Answers

Answer:

x + y = 34

10*x + 15*y = 410

Step-by-step explanation:

The equation system that models the situation would be made up of two equations:

The first equation would be the total number of hours for both jobs, that is, the number of babysat work hours and the number of yardwork work hours equals 34 total hours.

x + y = 34

The second equation would be the total amount of money earned, in this case it would be to multiply the earnings of each job by the number of hours of each job and add it up and you should give a total of 410 which are your total earnings.

10 * x + 15 * y = 410

Therefore the system of equations would be:

x + y = 34

10 * x + 15 * y = 410

Answers

Answer:

Step-by-step explanation:

since there is no sales tax,

Amount of money used to pay

= change + total price of items bought

Let's find the total price of the items she bought.

Chicken

1 package ----- $12.36

2 packages ----- 2($12.36)= $24.72

Broccoli

1 pound ----- $1.98

½ pound ----- $1.98 ÷2= $0.99

Milk

1 gallon ----- $3.49

Total amount paid

= $24.72 +$0.99 +$3.49

= $29.20

Thus, amount of money Susan used to pay

= $29.20 +$0.80

= $30

Answers

Answer: The number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .

Step-by-step explanation:

Given word = "EQUATION"

Total letters = 8

Total Vowels (EUAIO)=5

Total number of ways to arrage letters = 8!

Number of ways to arrange vowels in alphabetical order = 5!

Then, The number of ways that all the vowels are in alphabetical order will be :

Use absolute value to express the distance between −10 and 16 on the number line.

Answers

Answer: 26

Step-by-step explanation:

From -10 to 0 will be 10

1 to 16 are 16

Answer:

Step-by-step explanation:

There are several things you need to know in order to write the absolute value equation for a situation. First is how to formulate what you need. The absolute value equation follows the formatting:

| x - midpoint | = the distance between the midpoint and one of the endpoints.

That means we also need to be able to find the midpoint of -10 and 16. Finding the midpoint is finding the middle, which is the same as finding an average of the 2 numbers.

[tex]M=\frac{-10+16}{2}=3[/tex]

So the midpoint is 3. The distance between 3 and either one of the endpoints is going to be the same, by definition of the midpoint of the 2 numbers. The distance between 3 and 16 is 13 units. The distance between 3 and -10 is also 13 units. So, to put this into an absolute value equation,

| x - 3 | = 13

Answers

C

Step-by-step explanation:

yeah its C

The requried function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
The x-intercept is the point where the graph of a function intersects the x-axis. At this point, the value of y is 0. To find the x-intercept of each function, we set y equal to 0 and solve for x.

A. f(x) = 3x – 9

0 = 3x – 9

3x = 9

x = 3

B. f(x) = 1/x + 4

0 = 1/x + 4

-4 = 1/x

x = -1/4

C. f(x) = √(x+1)

0 = √(x+1)

x = -1

D. f(x) = x²

0 = x²

x = 0

Therefore, the function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

Step-by-step explanation:

tan47 = [tex]\frac{h}{c}[/tex]

c = [tex]\frac{h}{\text{tan}47}[/tex]

c = [tex]\frac{4.8}{\text{tan}47}[/tex]

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

b = [tex]\frac{h}{\text{tan}37}[/tex]

b = [tex]\frac{4.8}{1.0724}[/tex]

Now apply the tangent in triangle ABE,
