Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5
IceJOKER [234]

Answer:

1/15

Step-by-step explanation:

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

The amount of cereal she would have per day is calculated as:

5 days = 1/3 of the box

1 day = x

Cross Multiply

5 days × x = 1 day × 1/3 of the box

x = 1/3 ÷ 5

x = 1/3 × 1/5

x = 1/15 of the box

8. rajis annual salary ranges from $25 325 in the 1st year to $34 445 in the 7th year. The salaries in this range form an arithm
-Dominant- [34]

Answer:

a) $1520

b) S_7 = $209195

Step-by-step explanation:

The range of salaries forms an arithmetic sequence with the first term as 25325 and its 7th term as 34445:

a) The raise the person can get each year is the common difference of the progression, d.

The nth term of an arithmetic progression is given generally as:

a_n = a + (n - 1)d

where a = first term = 25325

d = common difference

Therefore, the 7th term (34445) will be:

34445 = 25325 + (7 - 1)d

34445 = 25325 + 6d

=> 6d = 34445 - 25325 = 9120

d = 9120 / 6 = $1520

Therefore, the raise the person gets each year (common difference) is $1520.

b) The total amount the person will earn after 7 years is the sum of the salaries of all 7 yeas.

The sum of an arithmetic progression up to the nth term is given as:

S_n = \frac{n}{2}(2a + (n - 1)d)\\ \\

Therefore, the sum of the person's salary for the 7 years is:

S_7 = \frac{7}{2}(2 * 25325 + (7 - 1)1520)\\ \\S_7 = 3.5 (50650 + 6(1520))\\\\S_7 = 3.5 (50650 + 9120)\\\\S_7 = 3.5 * 59770\\

S_7 = $209195

That is the total amount of salary after 7 years

Find the equation of a line which passes through the point (3, -1) with the gradient M=2÷3​
cluponka [151]

Step-by-step explanation:

Equ of line -

y=mx+c

Using point (3,-1)

3 as x, - 1 as y

M=2/3

Substitute the values of these coordinates

3=2/3(-1) +c - - - - now find for c

c= 3- (-2/3)

c= 3.67

Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with

y=2/3x + 3.67
