Decide whether the rates are equivalent. 126 points every 3 games 210 points every 5 games. What is the answer?

Mathematics
1 answer:
Sophie [7]3 years ago
6 0

Step-by-step explanation:

To find whether the rates are equivalent or not, we will use proportions.

\frac{126\text{ points}}{3\text{ games}}=\frac{210\text{ points}}{5\text{ games}}

Let us simplify our fractions.

42\frac{\text{ points}}{\text{game}}=42\frac{\text{ points}}{\text{game}}

We can see that both unit rates are same, therefore, the rates are equivalent and equal to 42 points per game.

For an A.P. ,The first two term are -3, 4. The 21st term is
Dahasolnce [82]

Answer:

The 21st term is 137.

Step-by-step explanation:

Arithmetic progression:

In an arithmetic progression the difference between consecutive terms is always the same, and its called common difference.

The nth term is given by:

a_n = a_1 + (n-1)d

In which a_1 is the first term and d is the common difference.

The first two terms are -3, 4.

This means that a_1 = -3, d = 4 - (-3) = 7

So

a_n = a_1 + (n-1)d

a_n = -3 + 7(n-1)

The 21st term is

a_{21} = -3 + 7(21-1) = -3 + 140 = 137

The 21st term is 137.

Oliga [24]
That's not a squre
anyway, we use ratios
base:person to corner=28:8
height to height=x:5
so
28/8=x/5 becasue same ratio
28/8=14/4=7/2
7/2=x/5
multiply
35/10=2x/10
35=2x
divide 2
