Answer:

  (b)  23

Step-by-step explanation:

The diagonals of a rectangle are the same length, so ...

  AC = BD

  2x +10 = 56

  x +5 = 28 . . . . . divide by 2

  x = 23 . . . . . . . . subtract 5

x = -4/11

Step-by-step explanation:

Answer:

100 or 110 degrees.

Step-by-step explanation:

Because a 90 degree angle is a right angle and 80 degree angle would be a acute angle.

Answer:

5

Step-by-step explanation:

All the angles add up to 180.

9v+6+7v+4+90=180

16v+100=180

v=5

Answer:

B) 11.8

Step-by-step explanation:

First write in 4 for x and 2 for y

Then multiply 1.3 times 6 (4+2) and subtract 2-6

Your expression should now be 7.8 +4

After adding these, it should be 11.8

Answer (assuming it can be in slope-intercept form):

[tex]y = \frac{1}{2}x-2[/tex]

Step-by-step explanation:

When knowing the slope of a line and its y-intercept, you can write the line's equation in slope-intercept form, or y = mx + b format. To write a full equation, substitute the m and the b for real values.

The m represents the slope of the line. Thus, substitute [tex]\frac{1}{2}[/tex] for m. The b represents the y-intercept. Thus, substitute -2 for b. This gives us the following equation and answer:

[tex]y = \frac{1}{2}x -2[/tex]

The percentage of pies baked that were not apple was 33.33 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The number of apple pies baked at the bakery = 13

The number of pecan pies baked at the bakery = 4

The number of pumpkin pies baked at the bakery = 3

So ,

Total number of pies baked at the bakery =
Number of apple pies baked at the bakery + Number of pecan pies baked at the bakery + Number of pumpkin pies baked at the bakery

Total number of pies baked at the bakery = 13 + 4 + 3

                                                                      = 21

Now ,

The number of pies that were not apple = Number of pumpkin pies baked at the bakery + Number of pecan pies baked at the bakery

The number of pies that were not apple = 4 + 3

                                                                   = 7

And ,

The percentage of pies that were not apple =

( The number of pies that were not apple / Total number of pies baked at the bakery ) x 100 %

The percentage of pies that were not apple = ( 7 / 21 ) x 100 %

                                                                         = ( 1 / 3 ) x 100 %

                                                                         = 33.33 %

Hence , the percentage of pies that were not apple is 33.33 %

Answer:

[tex]A= 35.8[/tex]

Step-by-step explanation:

Given

[tex]sin(53.2) = cos(A)[/tex]

Required

Find A

In trigonometry

[tex]sin(\alpha) = cos(\theta)[/tex]

Then

[tex]\alpha + \theta = 90[/tex]

So, this gives:

[tex]54.2 + A= 90[/tex]

Make A the subject

[tex]A= 90-54.2[/tex]

[tex]A= 35.8[/tex]

Answer:

C)22

Step-by-step explanation:

2x2x1=4

2x2x3=12

2x3x1=6

4+12+6=22

Given:

The expression is

[tex]9x^3-39x^2-30x[/tex]

To find:

The factors by grouping method.

Solution:

We have,

[tex]9x^3-39x^2-30x[/tex]

Taking out common factors, we get

[tex]=x(9x^2-39x-30)[/tex]

Splitting the middle term, we get

[tex]=x(9x^2-45x+6x-30)[/tex]

By grouping method, we get

[tex]=x(9x(x-5)+6(x-5))[/tex]

[tex]=x(x-5)(9x+6)[/tex]

Therefore, the factor form of given expression is x(x-5)(9x+6).

The domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex].

The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:

[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]

[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex]   (1)

Since the composite function is a square root function, then the domain fulfill the following inequation:

[tex]3\cdot x -3 \ge 0[/tex]

[tex]x \ge 1[/tex]

Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

Answer:

(x, y) = (-4, 3)

Step-by-step explanation:

x + y = -1 $|Rightarrow$ x = -1 - y

x - y = -7

Substituting the value of x (first equation) into the second equation, we get:

(-1 - y) - y = -7.

Simplifing, we get:

-1 -2y = -7

-2y = -6

y = 3.

Now that we know the value of y, we can solve the value of x by substituting y into the first equation. We get:

x = -1 - 3

x = -4

Step-by-step explanation:

Maybe you want to evaluate ...

  16 - 14 ÷ 2 + (3 +2)²

The parentheses are evaluated first.

  16 -14÷2 +5²

Then the exponential term.

  16 -14÷2 +25

The division is evaluated next.

  16 -7 +25

Finally, the sum is evaluated.
