Answer:

11a.  m <1 = 131          12a.  m <1 = 42

11b.  m <2 = 49          12b.  m <3 = 75

11c.  m <3 = 131          12c.  m <4 = 42

11d.  m <4 = 49          12d.  m <5 = 63

11e.  m <5 = 131         12e.  m <6 = 75

11f.  m <6 = 49          12f.  m <7 = 105

11g.  m <8 = 49          12g.  m <8 = 75

11h.  m <9 = 92          12h.  m <10 = 75

11i.  m <10 = 88          12i.  m <11 = 42

11j.  m <11 = 92          12j.  m <12 = 138

11k.  m <12 = 88         12k.  m <13 = 42

11l.  m <13 = 92         12l.  m <14 = 138

11m. m <14 = 88

11n.  m <15 = 92

Step-by-step explanation:

When lines are parallel to  each other than:

Corresponding Angles are equal.

Alternate Interior Angles are equal.

Alternate Exterior Angles are equal.

Consecutive Interior Angles add up to 180 degrees.

You can check some math websites for definitions of these angle relationships.

enrollment in the ski/snowboard club increased by 30% this year. there are now 182 students in the club. how many students were
eduard
Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now

now=182

percent means parts out of 100 so
130%=130/100=13/10


182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140

Find the value for x. Round your answer to the nearest hundredth. Area of the triangle = 8 ft^2​
zmey [24]

Answer:

x = 3.51

Step-by-step explanation:

Since, formula to determine the area f a triangle is,

Area = \frac{1}{2}(\text{Base})(\text{Height})

     8 = \frac{1}{2}(x + 1)(3x - 7)

16 = x(3x - 7) + 1(3x - 7)

16 = 3x² - 7x + 3x - 7

16 = 3x² - 4x - 7

0 = 3x² - 4x - 23

3x²- 4x - 23 = 0

By quadratic formula,

x = \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}

x = \frac{4\pm \sqrt{(-4)^{2}-4(3)(-23)}}{2(3)}

x = \frac{4\pm \sqrt{292}}{6}

x = \frac{4\pm 17.09}{6}

x = 3.51, -2.18

But the length of sides can't be negative.

Therefore, x = 3.51 will be the answer.

A football is kicked vertically upward from a height of 2 feet with an initial speed of 50 feet per second. The formula h=2+50t-
Oksanka [162]

Answer: 38 feet.

Step-by-step explanation:

The equation of motion of a body thrown vertically upwards:

                                       \displaystyle\\\boxed {h=h_0+v_0t-\frac{gt^2}{2} \ \ \ \ \ (1)},

h_0=2 \ feet\ \ \ \  v_0=50\  feet\  per\  second.

Substitute in formula (1) the value t=2 c:

h=2+50*2-16*2^2\\h=2+100-16*2*2\\h=102-64\\h=38\ feet.
