it is correct
Step-by-step explanation:
Answer: It becomes the tenth value of the number
Step-by-step explanation:
if the value of 9 in the number 506,092 is moved two places to the right then it changes it position from the ten place to the tenth place. It will become like this 506,020.9 the 9 is being move two places to the right.
Answer:
$3800
Step-by-step explanation:
When simple interest is added to the principal amount, the sum increases linearly with time. Essentially, you are asked for the y-intercept of a line that goes through the points (2, 6200) and (3, 7400). You can use the 2-point form of the equation of a line to find it:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (7400 -6200)/(3 -2)(x -2) +6200 . . . . fill in given points
y = 1200(x -2) +6200 . . . . . . . . . simplify some
y = 1200x -2400 +6200 . . . . . . simplify more
y = 1200x +3800 . . . . . . . . . . . . . completely simplify
When the number of years (x) is zero, the amount is 3800. The principal is $3800.
_____
The account is earning $1200 per year on a principal of $3800. The interest rate is about 31.6%, an unusually high value.
_____
<em>Alternate solution</em>
You can recognize that the interest earned in one year is 7400 -6200 = 1200. Since this is simple interest, the amount of interest earned each year is the same, so in 3 years, the account has earned 3×$1200 = $3600 in interest. Then the original principal amount must be ...
$7400 -3600 = $3800 . . . . . principal amount
The volume of a pyramid is computed by multiplying the base length, base width, and pyramid height and divide it by 3.
Volume = (base length x base width x height)/3
since this is a square, base length and width are equal.
w=l=10cm
h=12cm
Substituting the given values in the formula, we will get the volume of the pyramid
Volume=(10cmx10cmx12cm)/3
Volume= 400cm^3
