Please Help, thank you :)

Answer:

27*2/3=18

18*2/3=12

Step-by-step explanation:

I would look at the ratio of two terms

and the difference of two terms

to see if there might be a pattern

for example, 27, 18, 12

the difference between 27 and 18 is 9

the difference between 18 and 12 is 6

That is not a constant difference.

Let's try ratios:

27/18 = 1.5

18/12 = 1.5

that looks promising... we get the same ratio

so on the next bounce, expect

18/x = 1.5

maybe it's easier if we flip the ratio 1.5 (3/2) to 2/3 and so

18= 2/3 * 27

12= 2/3* 18 = 2/3 * 2/3 * 27

If we try to make a pattern

first peak = (2/3)^0 * 27

2nd peak = (2/3)^1 *27

3rd peak = (2/3)^2 * 27

Answer:

There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.

Because 84% out of 50 is 42

Answer:

$150

Step-by-step explanation:

A garden table and a bench together will cost $600. The actual values of the garden table and the bend are not given, but we know that the cost of a garden table will cost three times more than the bench.

Let [tex]x[/tex] = the cost of the bench.

Again, since the cost of the garden table is three times the cost of the bench ([tex]x[/tex]), we can represent the garden table as three times [tex]x[/tex] ([tex]3x[/tex]). These two terms will equal $600 when added, so let's formulate an equation:

[tex]3x+x=600[/tex]

Combine like terms:

[tex]4x=600[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:

[tex]x=150[/tex]

_

Check your work by substituting [tex]150[/tex] into the original equation:

[tex]3(150)+(150)=600[/tex]

[tex]450+150=600[/tex]

[tex]600=600[/tex]

Our answer is correct!

Answer:

D

Step-by-step explanation:

The formula matches up with the sequence. If you want to find f2 you look to f1 which is 8. Then you subtract by 2. This means to get f1, f0 would have to be 10 because 10-2 is 8.

Answer:

81°

Step-by-step explanation:

add both and subtract answer from 180

72+27=99

180-99=81

all 3 angles in a triangle always add up to 180°

Answer:

1 mile: 4 minutes

Step-by-step explanation:

This problem can be expressed with a simple ratio: 2:8

Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.

This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

For this situation we have the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where each variable represents a coordinate (e.g. in this case 4 could be [tex]y_{1}[/tex]). So first, let's define which coordinates will be the values of these variables:

(3,4): [tex]x_{1}, y_{1}[/tex]

(5,9): [tex]x_{2}, y_{2}[/tex]

Now we need to replace each variable with its given value: [tex]m = \frac{9-4}{5-3}[/tex]

And then do the subtraction to simplify: [tex]m=\frac{5}{2}[/tex]

Therefore, the slope of the line that passes through the points (3,4) and (5,9) is [tex]\frac{5}{2}[/tex].

Answer:

f(x)= (x+2)²

= x²+4+2x

then f(3) = 3²+4+2*3

= 9+4+6

add up the sum and here's your ans

Answer:

yes, these ratios are proportional.

Step-by-step explanation:

yes they are! proportional ratios are like equivalent fractions.

Answer:

39

Step-by-step explanation:

g(-5)=-7×(-5)+4=35+4=39

Answer:

g(-5) = 39

Step-by-step explanation:

g(x) = -7x + 4

g(-5) = - 7* (-5) + 4

        = 35 + 4

       = 39

Answer:

Step-by-step explanation:

18 is negative so add 18 to both sides

2x=8

so the answer would be 4 because

4 x 2= positive 8

Answer:

y= 9/4x+9

Step-by-step explanation:

you write the 9/4 as a fraction it looks a little confusing I don't have an actual fraction symbol so it's 9/4 then x plus 9 :)

Answer:

$975.13

Step-by-step explanation:

Answer:

the greatest common factor is B - 1

Step-by-step explanation:

not 5 because 85 doesn't end with 0 or 5

not 3 because 5+0 doesn't equal a multiple of 3

not 2 because 45 is odd

not 0 because that's never an answer

x + 11 ft

Step-by-step explanation:

x² + 22x + 121 ft² = area of square

x² + 11x + 11x + 121 ft² = side²

x(x + 11) + 11(x + 11) ft² = side²

(x + 11)(x + 11) ft² = side²

(x + 11)² ft² = side²

x + 11 ft = side²
