Using complementary angles concept, it is found that the measure of the complement is of 27º.

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

  • If two angles are complementary, their <u>measures add to 90º</u>, and thus, the complement of an angle x is given by 90 - x.
  • The measure of an <u>angle is 36 degrees greater than it's complement</u>, thus, the measure of the angle is given found using the following equation:

x = 90 - x + 36

2x = 126

x = \frac{126}{2}

x = 63

The complement is: 90 - x = 90 - 63 = 27.

The measure of the complement is of 27º.

Leto [7]

Answer:

95 ; 105

Step-by-step explanation:

Let :

Aanya's time = x

Krish's time = x + 10

Together = 50

Hence

Aanya's rate = 1/x

Krish's rate = 1/(x + 10)

Together rate = 1/50

Hence,

1/x + 1/(x + 10) = 1 / 50

((x + 10) + x) / x(x + 10) = 1/ 50

(2x + 10)/ x² + 10x = 1/50

50(2x + 10) = x² + 10x

100x + 500 = x² + 10x

x² + 10x - 100x - 500 = 0

x² - 90x - 500 = 0

Using the quadratic equation solver :

x = 95.24 ; x = - 5.24

Time can't be negative

Hence, x = 95 (nearest minute)

It takes Aanya 95 minutes Alone a ND

Krishna (95 + 10) = 105 minutes alone

Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp
mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P)  =  $1000 .

interest rate (R)  =  7.5 % .

Time period (T) =  1  year .

\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}

        = \frac{1000 * 7.5 * 1}{100}

         = $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

S . I =  \frac{4000 * 7.75 * 1}{100}

      = $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

                                                       = $ 385

What is the simplified form of the following expression?
Amanda [17]
You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.

8 = 4 * 2
You can take the square root of 4 and put it outside the root.

18 = 9 * 2
You can take the square root of 9 and put it outside the root.

5 \sqrt{8} - \sqrt{18} -2 \sqrt{2} =

= 5 \sqrt{4 \times 2} - \sqrt{9 \times 2} -2 \sqrt{2}

= 5 \times 2\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}

= 10\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}

= 5\sqrt{2}

Artist 52 [7]
For this case the distance will be given by:
 d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2
 Rewriting we have:
 d ^ 2 = (18) ^ 2 + (12) ^ 2
 d ^ 2 = 324 + 144
 d ^ 2 = 468
 d = root (468)
 d = 21.63 Km
 Answer:
 
1) She did not find the full distance each traveled in 1.5 hours.
 
2) She should have used 12 km for Joseph's distance and 18 km for Isabelle's distance.
