Answer:

20

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

First, we need to remember to use the order of operations:

Parentheses

Exponents

Multiplication/Division (whichever comes first)

Addition/Subtraction (whichever comes first)

Start by evaluating 2⁴ since exponents come first...

80/16*4

Now do the division first since it comes first in the equation...

5*4

Lastly do the multiplication...

Answer:

8xb + 456x

Step-by-step explanation:

8x(b + 456)

8xb + 456x

You multiply 8x by the numbers in the parenthesis. And you add the variables to the coefficents.

Answer:

12 years old

Step-by-step explanation:

let h = helmi's age and let s = son's age (right now)

10s = 3h

h + 5 + s + 5 = 62

h + s + 10 = 62

h + s = 52

3h + 3s = 156

10s + 3s = 156 (substitution)

13s = 156

s = 12

Answer:

The Area of the shaded region would be 100 in^2 .

Step-by-step explanation:

Given:

Check the Attachment.

To Find:

The Area of Shaded Region

Solution:

The Triangle and the Rectangle have the same base(b) that is equal to the length(l) of the rectangle.

Note that Height of the triangle is same as breadth of the rectangle.

Now Let's come in the main solving part :-

We know that the formula of Area of the Triangle is ;

[tex]\boxed{ \rm \: Area \: of \: Triangle= \tt \: 1/2× \rm \: base×height , i.e. \: \tt \: 1/2× \rm\: b×h}[/tex]

Substitute the values where Base= 20 in and Length = 10 in:

[tex] \tt \: Area \: of \: Triangle=1/2×20 \: \times 10[/tex]

Now Solve it.

[tex] \tt \: Area \: of \: Triangle= \cfrac{1}{ \cancel2 {}^{1} } \times \cancel{20} {}^{10} \times 10[/tex]

[tex] \tt \: Area \: of \: T riangle = 10 \times 10[/tex]

[tex] \tt \: Area \: of \: Triangle=\boxed{\tt 100 \: in {}^{2}} [/tex]

Hence, the area of the shaded region is 100 sq.in or 100 in^2 .

Answer:

  32°, 36°, 112°

Step-by-step explanation:

All of the angles are described in terms of the first angle, so we can use a variable to represent that: x. The second angle is (x+4) and the third angle is (3x+16). As always, the sum of angles in a triangle is 180 degrees:

  x +(x +4) +(3x +16) = 180

  5x +20 = 180 . . . . . collect terms

  5x = 160 . . . . . . . subtract 20

  x = 32 . . . . . . . divide by 5

  x+4 = 36 . . . . find the other two angles

  3x+16 = 3(32) +16 = 112

The angles of the triangular yard are 32°, 36°, and 112°.

The area of a shape is the amount of space it occupies

Using the assumed values, the area of the shaded region is 3 square meters

From the question, we understand that the rectangle is inscribed in the trapezoid

This means that, the area of the rectangle is smaller than the area of the trapezoid

The question is incomplete, so we make use of the following assumed values.

So, the shaded region would be

Shaded = 18 - 15

Evaluate the difference

Shaded = 3

Hence, the area of the shaded region is 3 square meters

Answer: x = 11; y = -1.

Step-by-step explanation:

-9y + 2 = x        (1)

-x - 3y = -8        (2)

Substitute x from Equation 1 into Equation 2:

-(-9y + 2) - 3y = -8

9y - 2 - 3y = -8

9y - 3y = -8 + 2

6y = -6

y = -1

Substitute y into Equation 1 and find x:

-9 * (-1) + 2 = x

x = 11

Answer:

y = 2/3x​

Step-by-step explanation:

[] Since the line goes through the origin (0, 0) the line will have no b. This does not rule out any of the options as they all have no b.

[] When we have clear points on a line, we can find the slope by using "rise-over-run." Here is an example using your problem;

-> The slope of the line will be positive because it is going from the bottom left to the top right.

We will start at (0, 0). We count up two units to (0, 2) and to the right three units too our next point, (3, 2). This leaves us with a slope of 2/3.

Explanation:

The key word here is "desired". We wish to make the errors as small as possible. The smallest any individual error can get is 0. Adding the entire collection of zeros will sum in a total of zero.

An error of zero means we hit the mark exactly. The unfortunate reality is that error is going to happen, so we'll have some positive error values with any regression line (or curve). It's only when all points are on the same line is when we have zero error and perfect interpolation rather than regression.

Again, the question is asking about desired error and the ultimate goal is to make the error zero. The next best thing is to minimize it as small as possible.

Step-by-step explanation:

[tex]2 - \frac{x + 1}{x - 2} - \frac{x - 4}{x + 2} = \: \frac{ax + b}{x {}^{2} - 4 } \\ = \: \: 2 - \frac{(x + 1)(x + 2) - (x - 4)(x - 2)}{x {}^{2} - 4 } \\ = \frac{2x {}^{2} - 8 - x {}^{2} - 2x - x - 2 - x {}^{2} + 2x + 4x - 8 }{x {}^{2} - 4 } \\ = \frac{ - 8 - 2 + 3x - 8}{x {}^{2} - 4 } \\ = \frac{3x - 18}{x {}^{2} - 4 } \\ [/tex]

so, a = 3, b = -18

You can replace "sum" with an addition sign.

You can replace "one-third" with 1/3.

Step-by-step explanation:

"the sum" means to add.

Let "a number" = x:

The sum of a number and one-third = x + 1/3.

You can replace "sum" with an addition sign.

You can replace "one-third" with 1/3.

Answer:

a)-0.95

b)1.49

c)-8.1

d)1.3

Step-by-step explanation:

a) just add the postive to the negative, pretty simple.

b) the two negatives in this problem cancel out so the new pronlem is adding -.85+2.34

c)Anything multiplied by one negative will have a negative product

d)Divide like regular, but anything that has two negatives equals a postive.

Let me know if you need more or the actual work.

Supplementary angles add to 180 degrees.

180 - 144 = 36

36/2 = 18

18 + 144 = 162

One angle is 18 and the other one is 162
