Arithmetic progression
2,5,8..
Total sum of Arithmetic progression is 392
Find:
Number of term
Computation:
First term a = 2
Difference d = 5 - 2 = 3
Sn = [n/2][2a + (n-1)d]
392 = [n/2][2(2) + (n-1)3]
392 = [n/2][4 + 3n - 3]
784 = [n][1 + 3n]
784 = n + 3n²
3n² + n - 784
n = 48 , n = -49
Number of term = 48
Answer:
To convert 1 meter into yards
Using the given facts : 100 centimeters in a meter, 2.54 centimeters in an inch, 12 inches in a foot, and 3 feet in a yard.
we can write these as;


and

1 ft = 12 inches
3 ft = 
Since,
1 inches = 2.54 cm
36 inches = 91.44 cm
Also,
1 m = 100 cm
or
1 cm = 
then;
91.44 cm = 
⇒ 1 yards = 0.9144 m
Divide both sides by 0.9144 we get;
1 meter =
yards.
Therefore, the answer is, 1 m = 1.1 yards (nearest to tenth)
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be:
and twice this sum would be: 
Thus, "twice the sum of y and 9" is: 
Answer:
-42
Step-by-step explanation:
Since she is handing them equally to her four nieces, then she has to do 10.50 x 4
= 42 since they are asking how much checks were cashed, the answer will be negative so therefore the answer is $-42
