Which is odd one out? Explain how you know?
15,000 ones 1,500 tens 15 thousands 15,000 15 ten thousands

Answer: 57 degrees

Step-by-step explanation:

Angle ZXY = Angle YZV = 75 degrees (Alternate segment theorem)

Since angles on a straight line add upto 180 degrees:

Angle UZX = 180 - ( 75 + 48) = 57 degrees

Note: 75 is Angle YZV and 48 is Angle XZY

Answer:

The answers is B

y=5/4x-4

Answer:

Step-by-step explanation:

The discriminant is found in

[tex]b^2-4ac[/tex] which is part of the quadratic formula. In

[tex]4x^2+10x-16=0[/tex], a = 4, b = 10, c = -16. Filling in for the discriminant:

[tex]10^2-4(4)(-16)=100+256=356[/tex]

It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.

In [tex]-16x^2-7x+3=0[/tex], a = -16, b = -7, c = 3. Filling in for the discriminant:

[tex](-7)^2-4(-16)(3)=49+192=241[/tex]

It's positive and not a perfect square so the 2 solutions are complex rational

Answer:

3y5 + 8y4 – 8y3

Step-by-step explanation:

2y5 – 6y3 + 1 + y5 + 8y4 – 2y3 – 1

2y5 + y5 + 8y4 – 6y3 – 2y3 + 1 – 1

3y5 + 8y4 – 8y3

Answer:

y = 10/8 = 1.125 or 1 1/4

Step-by-step explanation:

Inverse proportion means

xy = a constant.

In this case, the constant is given by the example,

x = 2 when y=5, so

xy=10

when x = 8, then

y = 10/8 = 1.125 or 1 1/4

this means that the height of students in class with range 6 may vary from person to person while that in class with range 3 maybe clustered around one another.

Answer:

0.99

Step-by-step explanation:

99% + 99% - 99% × 99% ÷ 99%

198% + 99% - 99% × 99% ÷ 99%

198% - 99%

so, 99 / 100

= 0.99

Answer:

0.99

Step-by-step explanation:

99% + 99% - 99% × 99% ÷ 99%

Add 99% and 99%

198% + 99% - 99% × 99% ÷ 99%

Divide 99% × 99% by 99%

198% - 99%

Subtract 99% from 198%

99%

By defination :- p% = p / 100

x=3-y

putting the value of x

in this

x²+y²=5

(3-y) ²+y²=5

9-6y+y²+y²=5

2y²-6y+9-5=0

2y²-6y+4=0

2y²-4y-2y+4=0

2y(y-2)-2(y-2)=0

(2y-2) (y-2) =0

2y-2=0 or y-2=0

y=1 or y=2

so x=2 or 1

Answer:

y = (x - 2)² - 9    Vertex form

y = x² - 4x - 5   Standard form

Step-by-step explanation:

vertex = (h, k) = (2, -9)

Vertex form

y = a(x - h)² + k

y = a(x - 2)² - 9

find "a" using point (5, 0)

0 = a(5 - 2)² - 9

0 = a(3)² - 9

0 = 9a - 9

9 = 9a

a = 1

y = (x - 2)² - 9

Standard form

y = (x² - 4x + 4)  - 9

y = x² - 4x - 5

Answer:

vertex = (- 1, - 4 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x - 3 ← is in standard form

with a = 1, b = 2 , then

x = - [tex]\frac{2}{2}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y

y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4

vertex = (- 1, - 4 )

  D.  $101,000 – $120,000

Step-by-step explanation:

The bar graph is not completely labeled, but in the context of the question it seems safe to assume that the vertical scale can be considered to represent relative frequency.

So, the shortest bar is the one with the lowest frequency. The horizontal scale identifies that as 101-120. If we assume that is salary in thousands of dollars, then Choice D is appropriate.

Answer:

72

Step-by-step explanation:

20 got 4 added to it and the only number that gives you 24 when you multiply it is 4x6 and we can prove that to be right because the one before it is 4x5 and it gives us 20. Now that we know the multiplier is 5 and 6 we can ask ourselves, "What do I multiply by 5 that gives me 60?" And that is 12. So 12x6 is 72 for x.

Answer:

11.9

Step-by-step explanation:

in maths, we are aware that in triangles we can use sine, cosine, and tangent.

using tangent, we have

tan 29⁰=6.6/x

and tan 29⁰=0.5543

0.5543=6.6/x

cross multiply

0.5543x=6.6

x= 6.6/0.5543

x= 11.9

Step-by-step explanation:
