If you were asked to find the 87th term in a sequence, which formula would you want to be given?

1 answer:

3 0

To determine the nth term of sequence, first we need to know what type of sequence is it. It can be an arithmetic sequence or a geometric sequence. For an arithmetic sequence, the nth can be determined by the formula,

an = a1 + (n-1)d

For a geometric sequence,

an = a1r^n-1

Hope this answers the question.

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play

choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

Roy

$x=42\ strokes\\y=9\ holes$

$\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole$

Alicia

$x=79\ strokes\\y=18\ holes$

$\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole$

Rickie

$x=123\ strokes\\y=27\ holes$

$\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole$

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole

Amanda cut a piece of wood that was 10/12 of a yard long. She used 3/4 of the wood how many yards of wood were left over

Nadya [2.5K]

The wood is 10/12 yard long.

She used 3/4 of the wood:
$\dfrac{3}{4} \times \dfrac{10}{12}$

$\dfrac{3}{4} \times \dfrac{2 \times 5}{3 \times 4}$

$\dfrac{3}{8} \text { yard}$

Calculate yards left:

$\dfrac{10}{12} - \dfrac{3}{8}$

$= \dfrac{20}{24} - \dfrac{9}{24}$

$= \dfrac{11}{24} \text { yard left}$
