Answer:

#15) B. 41

#16. A. 6

Step-by-step explanation:

<h2>#15:</h2>

You are given the Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of the right triangle.

In problem 15, x is the hypotenuse and 9 and 40 are the legs, so you can substitute these values into the formula and solve for c (x).

  • (9)^2 + (40)^2 = c^2

Evaluate the exponents.

  • 81 + 1600 = c^2

Add the like terms together.

  • 1681 = c^2

Square root both sides of the equation.

  • c = 41

Since c = x, the answer for #15 is b. 41.

<h2>#16:</h2>

x and 8 are the legs and 10 is the hypotenuse, so substitute these values into the formula. Make x = a.

  • a^2 + (8)^2 = (10)^2

Evaluate the exponents.

  • a^2 + 64 = 100

Subtract 64 from both sides of the equation.

  • a^2 = 36

Square root both sides of the equation.

  • a = 6

The answer is A. 6.

15. \:  x =  \sqrt{ {9}^{2} +  {40}^{2}  }  =  \sqrt{81 + 1600}  =  \sqrt{1681}  = 41 \\ 16. \: x =  \sqrt{ {10}^{2} -  {8}^{2}  }  =  \sqrt{100 - 64}  =  \sqrt{36}  = 6

Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue,
Mnenie [13.5K]

Answer:

Step-by-step explanation:

Let the total number of votes to choose a color = x

Number of votes for blue = \frac{5}{8}\times x

Remaining votes = x - \frac{5}{8}\times x

                            = \frac{8x-5x}{8}\times x

                            = \frac{3}{8}\times x

Votes for green = \frac{5}{9}\times (\text{Remaining votes})}

                          = \frac{5}{9}\times \frac{3x}{8}

                          = \frac{5}{24}\times x

Finally remaining votes = \frac{3x}{8}-\frac{5x}{24}

                                       = \frac{9x-5x}{24}

                                       = \frac{4x}{24}

                                       = \frac{x}{6}

Since these votes are for red therefore,

\frac{x}{6} = 48

x = 48×6

  = 288

a) Votes for blue are \frac{5x}{8}

Therefore, exact number for blue votes = \frac{5\times 288}{8}

= 5×36

= 180

b). Votes for green = \frac{5x}{24}

= \frac{5\times 288}{24}

= 60

c). Since 25 students were absent on that day of the vote, number of students at Riverside Elementary School = 288 + 25

= 313

d). Since seven tenths of the votes for blue were made by the girls.

Therefore, number of girls voted for blue = \frac{7}{10}\times 180

= 7×18

= 126

Since total votes made = 288

Therefore, half of the votes made = \frac{288}{2}

= 144

Now it's clear that number of votes made by girls is less than half of all the votes.

e). 126 girls voted for blue.

The value of X in the figure ABCD witch is a rhombus
NeX [460]

Answer:

  x = 10°

Step-by-step explanation:

The diagonals of a rhombus divide the figure into congruent right triangles. That means the two marked acute angles are complementary.

__

<h3>solve for x</h3>

Complementary angles total 90°, so the relation we can use to find x is ...

  (3x -13) +(8x -7) = 90

  11x = 110 . . . . . . . . . add 20

  x = 10 . . . . . . . . . divide by the coefficient of x

The value of x is 10°.
