Answer:

I think it's 32

Step-by-step explanation

I've done these types of questions before but don't really remember how to do the process but I think you multiply 8 and 16 and divide by 4.

Answer:

There are 6 angles between neighbour vertices, they all are equal (because a hexagon is regular) and their sum is 360°. Thus each angle has a measure of 360°/6=60°. Each subsequent rotation by 60° also maps a hexagon onto itself.

Option #1  (5:14)

Step-by-step explanation:

The reason I chose option relies fully on these steps:

To find the ratio that represents the situation, you have to find the denominator of the fraction that the ratio itself represents:

5 : 14

9 : 5

To find this element you count the total number of objects that are in the problem:

2 + 1 + 7 + 4 = 14 total marbles to choose from - our denominator.

But what about the other number? That's our numerator, and we can find that by counting how many of the select possibilities - only counting the red and green marbles that may be chosen:

1 + 4 = 5

Therefore our denominator and numerator come together to form 5/14, which is equivalent to 5 : 14!

I hope this helped a bunch! Tell me if you need any further assistance...

Answer:

  8x^2 -14x +3 = 0

Step-by-step explanation:

The sum of the roots is (3/2) +(1/4) = (6/4 +1/4) = 7/4.

The product of the roots is (3/2)(1/4) = 3/8.

The quadratic can be written as ...

  x^2 -(sum of roots)x +(product of roots) = 0

  x^2 -7/4x +3/8 = 0

Multiplying by 8 makes all of the coefficients be integers:

  8x^2 -14x +3 = 0

Answer:

The difference between a relation and a function is that a relationship can have many outputs for a single input, but a function has a single input for a single output. This is the basic factor to differentiate between relation and function. Relations are used, so those model concepts are formed.

Answer:

a) -4

b) +343

Step-by-step explanation:

a) 10 shares - loss $40

    1 share --- ?

? = 40 / 10 = 4 decrease

b) each week 7 members increase for 49 weeks

so total increase = 7 * 49 = 343

9514 1404 393

Answer:

  (a) -4 dollars

  (b) +343 members

Step-by-step explanation:

(a) The change in the value of each share is the total amount of change divided by the number of shares:

  change per share = (total change)/(number of shares)

  change per share = (-40 dollars)/(10 shares) = -4 dollars/share

The change in value for each share was -4 dollars.

__

(b) As with most rate problems, the quantity is the product of rate and time.

  growth = (7 members/week) × (49 weeks) = 7×49 members

  growth = 343 members

The change in the club's size was +343 members.

Answer:

17. D

18. B.

Step-by-step explanation:

m= (y2-y1)/(x2-x1)

m= (5--2)/(-3--2)

m = -7

sub x=-2 ; y = -2

y= mx+c

y= -7x+c

-2=-7x+ c

c= -16

y= -7x-16

Answer:

Step-by-step explanation:

x<-3

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality: 2*x-2-(-8)<0

1)  Pull out like factors :  2x + 6  =   2 • (x + 3)

2) Divide both sides by 2

3) subtract 3 from both sides x<-3

Step-by-step explanation:

In ordered pairs (a,b) a is the x value and b is a y value.

if we have 3x+y=6

if x=0, y=6 --> (0,6)

if y=0, x=2 -->(2,0)

if x=3, y=-3--> (3, -3)

if x=6, y= -12 --->(6, -12)

if x=6, y= -9 ---> (5, -9)

Answer:

For $1,200 at 14% for 24 months, Sally would be have to pay $57.62 per month, or $1,382.88 after 24 months. Neighbor Steve: For $800 at 32% for 16 months, Sally would have to pay $62.08 per month or $993.28 after 16 months. Even with the (much) higher interest rate, Sally would pay $389.60 less if she went with Neighbor Steve. Even better is that the monthly payments would be about the same for the given timelines. Sally would still want to weight the benefits of contracted work vs. non-contracted work.

Answer:

A

Step-by-step explanation:

x= total number of sets bought

y= total cost

Since each set costs 3 dollars, we can represent that with the equation y=3x, and the teacher also had a 2 dollar coupon, so we can subtract 2 from the equation, giving us y=3x-2

So, by looking at the charts, plug in x (the input), and see if the y (output) is the same as the equation represents.

So, the answer is A. To test, plug in the x and see if it gives the right y.

For example, 3 sets bought (x), so it will be represented as,

y=3x-2

y=3(3)-2

y=7

So when 3 is x, y is 7. Which is what answer choice A shows.

Answer:

The width of the garden is 44 feet.

Step-by-step explanation:

A rectangular shape has 4 sides, so the perimeter would be x + x + y + y. We know that the total is 190 feet, and the length is 7 feet longer than the width.

Let x be the width of the rectangle.

Let y be the length of the rectangle; (y = x + 7)

Equation: 190 = x + x + y + y

190 = x + x + (x + 7) + (x + 7)

Combine like terms: 190 = 4x + 14

Find x: 190 - 14 = 4x, 176 = 4x, x = 44.

44 feet is the width of the garden.

Check: 44 + 44 + (44 + 7) + (44 + 7) = 190

Answer:

y = 2.5x

Step-by-step explanation:

Note where all the points are.

When x = 0, y = 0

When x = 2, y = 5

When x = 8, y = 20

You simply need to find how much "y" is for each "x". Divide y with x:

5/2 = 2.5

Check. Plug in the x, and obtain the y:

y = 2.5x

y = 2.5(4) = 10 (True).

y = 2.5(8) = 20 (True).

Every year, the value of an antique vase appreciates by 20% of its value in the previous year. If the value of the vase was $180 000 in 2012, its value in 2010 was $125000

Step-by-step explanation:

Given the appreciation rate r, the initial value I, the final value V, and the period of appreciation n, the formula for appreciation is given by:

V = I(1 + r)ⁿ

In our case, we need to work out the value of n.

We do this as follows:

n =2012 - 2010 = 2 years

Substituting the values we have:

180000 = I(1.20)²

180000 = 1.44I

I = 180000/1.44

= 125000

So, in 2010, the value of the vase was $125000

Answer:

Yes

Step-by-step explanation:

if you think of a slope equation, for example y= 3x + 2, if you do the opposite reciprocal, you would get-1/3 because you flip it around, and you flip the sign.
