Answer:

1562.05

Step-by-step explanation:

A = P(1 + r/n)^(n*t)

A = 1240(1 + 0.08/1)^(3*1)

A = 1562.04288

A = 1562.05

Step-by-step explanation:

arithmetic sequence : every new item of the sequence is created by adding a constant term to the previous item - in this case 195.

a1 = 3087 (that's our starting value)

a2 = a1 + 195

a3 = a2 + 195 = a1 + 2×195

an = a1 + (n-1)×195

a)

when he is 45 years old, that is 20 years (and 20 annual increments) plus to our starting value.

so, n = 1+20 = 21

a21 = a1 + 20×195 = 3087 + 20×195 = 6987

so, when he is 45 years old, his monthly salary will be RM6,987

b)

how many years (= how big is n) until he gets 8937 ?

8937 = a1 + (n-1)×195 = 3087 + (n-1)×195 =

= 3087 + n×195 - 195 = 2892 + n×195

6045 = n×195

n = 6045/195 = 31

so, a31 = 8937

and that means, he has to work 30 additional years (31 minus the starting level 1) to earn monthly RM8,937.

that means he will be 25+30 = 55 years old.

Answer:

72 quarts

Step-by-step explanation:

1 year = 12 months, and Neil changes the oil each month, and each month he uses 6 quarts of oil.  So, the number of quarts he will need for a year is

6 + 6 + ... + 6, twelve times, which equals 12(6) = 72 quarts.

Answer:

The difference is 17 degrees.

Step-by-step explanation:

You want to take your final temperature which in this case is 97°F, and then subtract it from the starting temperature which is 80°F. Doing this will help you find your difference.

97-80 = 17°F

Step-by-step explanation:

a))) -31-71=-102

b)-9+14=+5

Hi there!  

»»————-　★　————-««

I believe your answer is:  

A. - 31 - 71 = - 102

B. - 9 + 14 = 5

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

A. The minuend, subtrahend, and difference are parts of a subtraction problem. In the subtraction problem, - 31 - 71 = - 102, the number - 31 is the minuend, the number 71 is the subtrahend and the number - 102 is the difference.

B. When you are adding a negative number to a positive number you are effectively subtracting the second number from the first. ... And then you add the negative number, which means you are moving to the left – in the negative direction.

⸻⸻⸻⸻

Answer:

I think this would be 33,222 I don't know I feel positive about this.

Step-by-step explanation:

Answer:

It would be 162

Step-by-step explanation:

690 x 0.235 = 162.15 which rounds to 162

Step-by-step explanation:

substitute x= -1 into the equation to get the remainder

remainder= -2

the remainder is not a fraction

no, it is not a factor since its remainder is not zero

Step-by-step explanation:

a triangle is equal to 180 degrees

180 minus 36 gives us 144

144 divided by 8c equals 18

c equals 18

We move all terms to the left:

7x-19-(x+5)=0

We get rid of parentheses

7x-x-5-19=0

We add all the numbers together, and all the variables

6x-24=0

We move all terms containing x to the left, all other terms to the right

6x=24

x=24/6

x=4

Answer:

308

Step-by-step explanation:

144+108+56=308

=====================================================

Work Shown:

We have this set of data

[tex]\begin{tabular}{|l|l|}\textbf{game} & \textbf{goals}\\ 1 & 5 \\ 2 & 6 \\ 3 & 6\\ 4 & x \end{tabular}[/tex]

where x is some positive whole number. Add up everything in the second column:

5+6+6+x = x+17

This represents the total number of goals made over the four games.

Divide this over the number of games played (4) and set that equal to the mean of 6. Solve for x.

(x+17)/4 = 6

x+17 = 4*6

x+17 = 24

x = 24-17

x = 7

7 goals were scored in the fourth game.
