Answer:

b. tilt of moon

Step-by-step explanation:

it would be the same reason we get our season because the moon is not directly on its vertical axis

Step-by-step explanation:

Answer:

She gets paid $9 per hour.

Step-by-step explanation:

36/4 = 9

Answer:

3%  to as high as 80%

Step-by-step explanation:

Given:

[tex]x^2+2x-7=(x+a)^2+b[/tex]

To find:

The values of a and b.

Solution:

We have,

[tex]x^2+2x-7=(x+a)^2+b[/tex]

It can be written as

[tex](x^2+2x)-7=(x+a)^2+b[/tex]

Add and subtract square of half of coefficient of x in the parenthesis.

[tex](x^2+2x+(\dfrac{2}{2})^2-(\dfrac{2}{2})^2)-7=(x+a)^2+b[/tex]

[tex](x^2+2x+1^2)-1-7=(x+a)^2+b[/tex]

[tex](x+1)^2-8=(x+a)^2+b[/tex]     [tex][\because (x+y)^2=x^2+2xy+y^2][/tex]

[tex](x+1)^2+(-8)=(x+a)^2+b[/tex]

On comparing both sides, we get

[tex]a=1[/tex]

[tex]b=-8[/tex]

Therefore, the value of a is 1 and the value of b is -8.

he will need to score 32 points per game he wil; beat the record by 3 points with 190,meaning the new median is greater than the older median so your answer is C.

Answer:

C

Step-by-step explanation:

Answer:

1. m<13

2. x≥1

3. p>-3

Step-by-step explanation:

1. m-7<6

Add seven to both sides

m<13

2. x+4.5≥5.5

subtract 4.5 from both sides

x≥1

3. p+12>9

subtract 12 from both sides

p>-3

Answer:

9

Step-by-step explanation:

I would guess it looks like this - if not then tell me

[tex] \frac{18}{ \frac{2 \times 3}{5 - 2} } [/tex]

2×3=6

5-2=3

Then there's only

[tex] \frac{18}{ \frac{6}{3} } [/tex]

Which is equal to

[tex] \frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9[/tex]

Answer:

Choice D: not possible

Step-by-step explanation:

The reason why it's not possible is that when you try to make an equation it never comes out correct. You could also try plugging in the numbers then figure it out that way. It's not possible either way you do it.

Answer:

[tex]y = \frac{1}{7} x + 7[/tex]

Step-by-step explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

[tex] \frac{7y}{7} = \frac{49}{7} + \frac{x}{7} [/tex]

[tex]y = 7 + \frac{1}{7} x[/tex]

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

[tex]y = \frac{1}{7} x + 7[/tex]

Median = 37

Due to the number sequence being an odd number (11 numbers) the median is equal to 37, as there is five numbers that lead up to it.

Answer:

The answer is D. An observational study

Step-by-step explanation:

The researchers are observing how different diets in the cattle affects their body composition. They are not counting a population or anything so it is not a census. It is not a sample survey because they aren't asking cows and it is not an experiment because they are not changing or testing anything. They are just viewing meaning it is an observational study.

sqrt 63  = sqrt9 * sqrt7

            = 3 sqrt7

Step-by-step explanation: i probally did it wrong :(

Answer:

P(t) = 82,100(1.02)^t

 1.t is the time in years  

2.P(t) is the population after t years

3. 100%=1       102-100=2% so the interest rate is 2 %

   102%=1.02

4. after 15 year just put in term s of 't' (wich is represent the years) 15 :

Answer:

  a)  x = 7

  b)  m∠1 = 45°

  c)  m∠2 = 135°

Step-by-step explanation:

a) Same-side interior angles are supplementary, so we have ...

  ∠1 +∠2 = 180

  (7x -4) +(20x -5) = 180

  27x = 189

  x = 7

__

b) The measures of the angles can be found by substituting the value of x into the express for the angle measure.

  m∠1 = 7x -4 = 7(7) -4 = 45

  m∠1 = 45°

__

c) Angle 2 is the supplement of angle 1, so ...

  m∠2 = 180° -45°

  m∠2 = 135°

__

d) We used the relationship of angles at a transversal and the properties of equality.

Answer:

$386

Step-by-step explanation:

If Ann has to pay $2316 twice a year

(every 6 months), then, we calculate

$2316/6 = $386 every month.

Hence, Ann's budget for health

insurance each month is $386.

Answer:

The solution is (2, 1).

All other ordered pairs do not work.

Step-by-step explanation:

-2x + 5y = 1

5x - 3y = 7

-10x + 25y = 5

10x - 6y = 14

19y = 19

y = 1

5x - 3(1) = 7

5x = 10

x = 2

(2, 1)

The solution is (2, 1).

All other ordered pairs do not work.
