Geometry

Congruency All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Define

3(x + 7)° = 63°

3(x + 7)° + 63° + y° = 180°

Step 2: Solve for x

Divide 3 on both sides:                    x + 7 = 21 Subtract 7 on both sides:                 x = 14

Step 3: Solve for y

Substitute in x:                    3(14 + 7) + 63 + y = 180(Parenthesis) Add:              3(21) + 63 + y = 180Multiply:                               63 + 63 + y = 180Combine like terms:           y + 126 = 180Isolate y:                              y = 54

Answer:

Step-by-step explanation:

Heya, the correct answer is David. The tricky part is the Hours and minutes difference. by dividing 360 by 6 we'll get 60. That equals an hour. Which is what the original answerer got wrong. So, If we divide 180 by 6 we get 30. So actually, there is an 8-number difference between Alex's and David's answers. With David being right. 22-30

Answers

9514 1404 393

Answer:

  ₹172.25 at 4.5%

Step-by-step explanation:

The growth factor is the ratio of the values at the end and beginning of the second year:

  multiplier = 188.10/180 = 1.045 = 1 + 4.5%

The amount put out is the amount at the end of the first year, divided by this growth factor.

  P = A/(1+r) = 180/1.045 = 172.25

The sum put out is ₹172.25, and the rate of interest is 4.5%.

Using PEMDAS solve
22/2x3

Answers

22/2 = 11
11 x 3 = 33

Okay, let me help you.

PEMDAS is just order of operations. P - Parentheses, E - Exponents, M - Multiplication, D - Division, A - Addition, and S - Subtraction.

/ this symbol means to DIVIDE.

Since division is at the beginning of the equation, you start with 22 ÷ 2 x 3

Let's break this down...

2 x 3 = 6

22 ÷ 6 = 3.66...  and on with the 6's.

The answer to this equation, is

Which value is in the domain of f(x)?

Answers

Answer: x = 4

Step-by-step explanation:

Here we have a piecewise function.

One piece works for values of x such that:   -6 < x < 0

And the other piece works for values of x such that: 0 < x ≤ 4

Then the domain of this function is:

D = (-6, 0) U (0, 4]

Notice that, becuse we use the symbols ><, the values of x:

x = -6

x = 0

Do not belong to this domain.

While becuase we use the symbol ≤ in the right end, the value x = 4 does belong to the domain.

Then for the given options, the only value that belongs to the domain is the third option, x = 4.

X + 8 = 5; X = ?
6 = X = 2; X = ?
X = 3 = 3; X = ?
X + 10 = 7; X = ?
36 - X = 6; X = ?
14 = X = 2; X = ?
50 = X = 5; X = ?
5X = 10; X = ?
X = 7 = 6; X = ?
X-4 = 2; X = ?

Find the rectangular coordinates of (7, 150°)

Answers

Answer:

The coordinates are (-7sqrt(3)/2, 7/2).

Step-by-step explanation:

The rectangular coordinates from polar coordinates is found by:

x = r*cos(theta)

y = r*sin(theta)

Substituting the given values, we get:

x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2

y = 7*sin(150 deg) = 7*(1/2) = 7/2

The coordinates are (-7sqrt(3)/2, 7/2).

$0.32 to $.37

Answers

Answer with explanation:

Percentage change =  [tex]\dfrac{Change}{Previous\ value}\times100[/tex]

a) 3 months to 5 months

Change = 5 - 3  ( increase )

Percentage change = [tex]\dfrac{2}{3}\times100\%=66.67\%[/tex] , it is an increase .

b) 5 to 10

Change = 10-5 = 5  ( increase)

Percentage change = [tex]\dfrac{5}{5}\times100\%= 100\%[/tex], it is an increase .

c) $0.32 to $.37

Change = 0.37-0.32 = 0.05 ( increase)

Percentage change = [tex]\dfrac{0.05}{0.37}\times100\%=13.51\%[/tex], it is an increase .
