Why it is important to study Geometry?

Answer

12. x = 15, y = 21

13. x = 10, M = 37, N = 84, P =59

14. x = 19, R = 43, S = 20, T = 117

15. A = 21, B = 125, C = 34

16. J = 48, K = 57, L = 75

Explanation

12. 6x - 11 + x + 5 + 81 = 180

     7x + 75 = 180

     7x = 105

     x = 15

     4y - 18 + y + 14 + 6*15 - 11 = 180

     5y + 75 = 180

     5y = 105

     y = 21

13. 4x - 3 + 9x - 6 + 6x - 1 = 180

    19x - 10 = 180

    19x = 190

    x = 10

    M = 4*10 - 3 = 37

    N = 9*10 - 6 = 84

    P = 6*10 - 1 = 59

14. R = 2x + 5

    S = x + 1

    T = 7x - 16

    2x + 5 + x + 1 + 7x - 16 = 180

    10x - 10 = 180

    10x = 190

    x = 19

   R = 2*19 + 5 = 43

   S = 19 + 1 = 20

   T = 7*19 -16

15. A = C -13

    B = 4C - 11

    c - 13 + 4c - 11 + c = 180

    6c -24 = 180

    6c = 2-4

    C = 34

   A = 34 - 13 = 21

   B = 4*34 - 11 = 125

16. K = J + 9

     L = 2J -21

     j + 9 + 2j - 21 + j = 180

    4j -12 = 180

    4j = 192

    J = 48

    K = 48 + 9 = 57

    L = 2*48 -21 = 75

Answer:

5

Step-by-step explanation:

For these types of problems, we can use cross - multiplication.

4/32 = x/40

Notice that since 40 and 32 are both measured in minutes, we put them on the same line.

Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.

Step-by-step explanation:

CD = 6 cm because opposite sides are equal

angle d = 110

Answer:

yes

Step-by-step explanation:

The commutative property of multiplication states that you can switch the order of the numbers you are multiplying.

So, (-2x^3 + x - 5)(x^3 - 3x -4) = (x^3 - 3x -4)(-2x^3 + x - 5)

the answer does not change just because the order of the numbers switches.

Hi there!

Yes,

To find the answer you must simplifly the two equation terms which means that if you turn it around you’ll still find the same answer which also means that the product -2x³+x-5 and x³-3x-4 is equal to the product x³-3x-4 and -2x³+x-5..

This is also the commutative property of multiplication.

Answer:

The satellite needs to be about 6,000 to 12,000 altitude because the higher it is the more it can connect to technology on earth

Step-by-step explanation:

Im not 100% sure but this is what I got for this question

The satellite needs to be about 6,000 to 12,000 altitude above the surface of Earth need to be so it provides the maximum coverage of its signal.

What should be the altitude of the satellite ?

A communications company is planning to launch a new satellite into orbit to improve the operation of its network. The longest distance that the satellite can send a reliable signal is 4,500 miles.

Thus, The company is trying to determine the optimal height to operate the satellite so that it has maximum coverage of Earth within its range.

The satellite needs to be about 6,000 to 12,000 altitude because the higher it is the more it can be connect to technology on earth.

Answer:

74

Step-by-step explanation:

So, what you have to do s 7.4 times 10 and then you get the anwser 74.

Answer:

4 seconds

Step-by-step explanation:

[tex]\frac{30,000}{1} =\frac{2,000}x}[/tex]

The numerator is the distance and the denominator is the time.

I used cross multiplication, the numerator of one fraction times the denominator of the other.

[tex]30,000*x=2,000*1\\30,000x=2,000[/tex]

divide both sides by 30,000 and simplify

[tex]x=\frac{2,000}{30,000} \\x=\frac{2}{30}[/tex]

Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)

[tex]x=\frac{4}{60}[/tex]

Since the denominator is 60, the number of seconds in a minute, the numerator is the answer

I hope this makes sense ;-;

Answer:

D : $105

Step-by-step explanation:

I use Proportional Reasoning.

part    percent

whole   100  is the formula.

We are looking for the part so we will keep that as "x"

x       35

300   100

100 x 3 is 300. So 35 x 3 is 105. Thats the answer!

Answer:

Step-by-step explanation:

He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).

The expected number of 3's in one throw is:

5/6 * 0 + 1/6 * 1 = 1/6

because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D

So he should expect (60 * 1/6 = 10) 3's in 60 throws.
