Answer:

118°

Step-by-step explanation:

<rpq = <vpq = 2x (opp angles are equal)

<rps = 90-2x

7x+54+ 2x+2x+90+90-2x = 360

9x= 180-54=126

x=14

arc sv = 90+2x = 90+28=118°

Answer:

  0.012987...(6-digit repeat)

Step-by-step explanation:

You explain it the same way you explain any division of decimal numbers.

The usual procedure is to adjust both numbers so that the divisor is an integer. Here, that is accomplished by multiplying each number by 100. This makes the problem ...

  1.82/140.14 = 182/14014

Now, division proceeds in the usual way. The first non-zero quotient digit will appear in the hundredths place. The quotient is a repeating decimal with a 6-digit repeat. You recognize the repeat as soon as you see 182 as a remainder.

Simin's behavior is an example of buying for the wrong reason.

Simin's main motivation was the fact she did poorly on her exam and due to this, she decides to buy clothes to "feel better".

Simin's behavior shows impulsiveness when deciding how to use money or what to buy. Indeed, Simin's reason to buy the clothes is not the best because it is based on emotions rather than on logic. Based on this, Simin's actions are an example of buying for the wrong reason.

Note: This question is incomplete because the options are not provided. Here are the options:

A. Using credit wisely.

B. Trying to impress her friends.

C. Buying for the wrong reason.

Answer:

  x ≈ 4.5

Step-by-step explanation:

Let y represent the hypotenuse of the smaller triangle. The Pythagorean theorem tells us the sum of the squares of the legs is equal to the square of the hypotenuse. This lets us write two equations:

  1² +2² = y²

  y² +x² = 5²

Using the first equation to substitute for y² in the second equation, we get ...

  1² +2² +x² = 5²

  1 + 4 + x² = 25 . . . . compute the squares

  x² = 25 -5 = 20 . . . subtract 5

  x = √20 ≈ 4.472 . . . . take the square root

Answer:

original price = $40

Step-by-step explanation:

if 70% ---> $28 then

1% ---> $28/70 = $0.4

then we know original price should be 100%

original price = 100 * 0.4 = $40

The function is decreasing when f(x) decreases as x increases.

We can observe one section that is increasing, it is when:

So excluding this section, the decreasing sections are:

Answer:

1256.64

Step-by-step explanation:

To find the area of a circle, the formula is πr2.

R stands for radius, and since the radius of a circle is always half the diameter we can figure this problem out.

If the diameter is 40, the radius is 1/2 of that, so the radius is 20. Now knowing the radius is 20, plug that into our formula and then we'll get the answer.

A = πr2 = π · 20^2 ≈ 1256.63706

≈ 1256.64

Answer:

24°

Step-by-step explanation:

because a right angle measures 90°. so 90° minus 64° is 24°.

Answer:

26°

Step-by-step explanation:

The sum of all degrees in a triangle is 180°.

You already have the value of two angles, 90° and 64°.

64+90=154

180-154= 26°

Answer: 150.77 and 29.23

==============================================

Explanation:

x = larger angle

y = smaller angle

x-y = difference of the angles = 121.54

x-y = 121.54 is one equation

x+y = 180 is the other equation since supplementary angles always add to 180 (they form a straight line).

We have this system we're working with

[tex]\begin{cases}x-y = 121.54\\x+y = 180\end{cases}[/tex]

Add the equations straight down.

We're left with this reduced equation

2x = 301.54

Divide both sides by 2 to isolate x

x = 301.54/2

x = 150.77

Use this to find the value of y

x-y = 121.54

150.77-y = 121.54

-y = 121.54-150.77

-y = -29.23

y = 29.23

Or we could say

x+y = 180

150.77+y = 180

y = 180-150.77

y = 29.23

---------------

Summary:

x = 150.77 and y = 29.23 are the two angles.

I'll let you check the answers.

Answer:

150.77° and 29.23°

Step-by-step explanation:

Let:

The sum of the angles is 180*

The difference is 121.54°

The system of equations:

[tex]\left \{ {{x+y=180} \atop {x-y=121.54}} \right.[/tex]

Solve:

Now we know what x is, we can plug it into the first equation to solve for y.

Answer:

132 cm^2

Step-by-step explanation:

First find the area of the rectangle on top:

4 * 7 = 28 cm^2

Remember: Don't forget units!

Next, find the average of the trapezoid's bases:

(7 + 19) / 2 = 26 / 2 = 13

Then, find the area of the trapezoid using (avg(bases) * height):

13 * 8 = 104 cm^2

Finally, add the two areas:

28 + 104 = 132 cm^2
