<h3>Answer: D) common ratio</h3>

Explanation:

The four points on this curve are

(1, 3) ,  (2, 6),  (3, 12) ,  (4, 24)

The equation of the curve that goes through all the points mentioned is

y = 3*2^(x-1) which is equivalent to y = 1.5*2^x

Both equations are exponential equations.

Sequences of the form

a(n) = a*(r)^(n-1)

are geometric sequences with common ratio r. In this case, r = 2.

Note how the jump from 3 to 6 is "times 2", so is from 6 to 12, and from 12 to 24. We multiply each term by 2 to get the next one.

The owner of a local farm sells baskets of fresh tomatoes in the summer time. Each basket is priced according to its mass rounde
elixir [45]

Answer:

4 1/10 kg

Step-by-step explanation:

To find the total mass, we add the mass of the three baskets

1 1/10 + 1 3/10 + 1 7/10

Since they have the same denominator

 1   1/10

 1   3/10

 1   7/10

-------------

 3  11/10

Change the improper fraction to a mixed number

11/10 = 1 1/10

3 + 1 1/10

4  1/10

Answer: 230cm²

Step-by-step explanation:

>We can do this by splitting the figure into 2 trapeziums.

>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula: \frac{1}{2} * (a+b) * (total height).

>Thus,

Area = \frac{1}{2} *(7+16)*20=230

Andre and Elena are reading the same book over the 1 summer. Andre says he has read of the book. Elena ! says she has read 20 mo
ddd [48]

Answer: There are 175 pages in the book.

Step-by-step explanation:

If Elena read 20 more pages than Andre and she read 55 pages, to find out how much Andre read you have to:

55-20= the pages Andre read

55-20=35

Andre read 35 pages.

If Andre read 1/5 of the book, then to find how many pages are in the book, you have to multiply 35 x 5. (Multiply by the reciprocal)

35 x 5= 175

There are 175 pages in the book.

Use diagrams or the description of equivalent ratios to show thay 2:3,4:6, and 8:12 are equivalent
VikaD [51]
So
lets say we have
a/b=2a/2b
we know that if we invert one and multiply it by the other (divide them), we get 1 because a/a=1 where a=a

so
2/3 and 4/6 are equivelent because if you divide them we get 12/12=1

2/3 and 8/12 are equivilent because if you divide them we get 24/24=1

and sinde 2/3=4/6 and 2/3=8/12, 2/3=4/6=8/12

they are equivlent
