Mathematics

serg [7]2 years ago

Answer:

Step-by-step explanation:

61)4 + 5(p-1) = 34     {Distributive property}

    4 + 5p - 5 = 34   {Add like terms}

         5p - 1   = 34     {Add 1 to  both sides}

             5p  = 34+1

              5p = 35  {Divide both sides by 5)

                p  = 35/5

               p = 5

62)    Smaller angle = x

Larger angle = x +50

x + (x +50) = 180       {Supplementary angles}

 2x + 50   = 180  {Subtract 50 from both sides}

          2x  = 180 -50

            2x = 130

              x = 130/2

            x = 65

Smaller angle = 65

Larger angle = 65 + 50 = 115

63) ΔBAD , ΔBCD

BA ≅ BC

∠A ≅ ∠C

AD ≅ CD

ΔBAD ≅ΔBCD        {S A S congruent}

64) Selling price = ₹ 5500

Profit = 10%

Cost price = \frac{100}{100+profit}*SP\\\\= \frac{100}{100+10}*5500\\\\=\frac{100}{110}*5500\\\\=100*50\\\\=5000=

Which statement is true about f(x) = –6|x + 5| – 2?
snow_lady [41]

Answer:

Step-by-step explanation:

"The graph of f(x) is a horizontal compression of the graph of the parent function" is true; the graph will appear to be narrower than that of y = |x|.  I would prefer to state "the graph of f(x) exhibits vertical stretching of the original (parent) function graph."

A baseball player gets 16 hits in 40 at bats. What percent of his at bats did not result
Katarina [22]

Answer:

40 percent

Now percentage formula

Whatever

- - - - - - - - - - x 100

Total whatever

In this case your whatever is the hits. according to the question, if i said he had 40 hits in 40, that's a 100percent. So... Your whatever is 16, total whatever is 40

16

- - - - - - x 100

40

= 40 percent

Help me to answer this pls​
nlexa [21]

Problem 1

x = measure of angle N

2x = measure of angle M, twice as large as N

3(2x) = 6x = measure of angle O, three times as large as M

The three angles add to 180 which is true of any triangle.

M+N+O = 180

x+2x+6x = 180

9x = 180

x = 180/9

x = 20 is the measure of angle N

Use this x value to find that 2x = 2*20 = 40 and 6x = 6*20 = 120 to represent the measures of angles M and O in that order.

<h3>Answers:</h3>
  • Angle M = 40 degrees
  • Angle N = 20 degrees
  • Angle O =  120 degrees

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

Problem 2

n = number of sides

S = sum of the interior angles of a polygon with n sides

S = 180(n-2)

2700 = 180(n-2)

n-2 = 2700/180

n-2 = 15

n = 15+2

n = 17

<h3>Answer: 17 sides</h3>

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

Problem 3

x = smaller acute angle

3x = larger acute angle, three times as large

For any right triangle, the two acute angles always add to 90.

x+3x = 90

4x = 90

x = 90/4

x = 22.5

This leads to 3x = 3*22.5 = 67.5

<h3>Answers:</h3>
  • Smaller acute angle = 22.5 degrees
  • Larger acute angle = 67.5 degrees
