cricket20 [7]

Answer:

The first one

Step-by-step explanation:

The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.

There are 40 monkeys and 60% of the monkeys are in the trees. How many monkeys are in the trees?
strojnjashka [21]

Answer:

24 monkeys are in the tree

Step-by-step explanation:

We solve it by writing \frac{60}{100} times \frac{40}{1}

Why is it over 100? Because every percent is out of 100!

\frac{60}{100} X \frac{40}{1} (your equation)

60 times 40 = 2400 and 100 times 1 = 100, We get, \frac{2400}{100},

Lastly, we simplify the fraction by 100 on each side:

\frac{2400}{100} / \frac{100}{100}

you get 24

The common difference ,d in an arithmetic sequence whose fourth term is 16 and whose seventh therm is 31
Natali [406]

Answer: d=5

Step-by-step explanation:

Arithmetic progression

An=a1+d(n-1)

An= nth term

A1= first term

D= common difference

N= nth position

We are given the 4th and 7th terms

For 4th term,n=4

A4=a1+d(4-1)

A4= 16

16= a1+d(4-1)

16= a1+3d........equation 1

For the 7th term,n=7

A7=a1+d(7-1)

A7= 31

31=a1+6d......equation 2

Bring them together

16=a1+3d

31=a1+6d

Subtract equation 1 from 2

So we have

15=3d

D=15/3

D=5

Therefore, the common difference is 5
