Answer:
x = x2 - x1 = -8 -2 = -10
y = y2 - y1 = -1 -4 = -5
diameter = (x^2 + y^2)^1/2 = (100 + 25)^1/2 = 11.18
radius = 11.18 / 2 = 5.59 or 1/2 the diameter.
Step-by-step explanation:
Answer:
A monomial.
Step-by-step explanation:
Answer:
$14025.52
Step-by-step explanation:
The Total amount after a compound interest can be calculated using the formula:
where P is the amount of deposit, R is the rate of interest, n is the duration.
Hence by substituting the values, we get:
T = <u>$14025.52 (nearest cent)</u>
Answer:
(507.05, 592.95)
Step-by-step explanation:
Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error =
Substituting the values in above equation
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
Answer:
exActual room size: 8 ft 7 in x 5 ft 2 in
Convert to inches, actual room size: 103 in x 62 in
103" x 62"= 6386 inches / 144 (1 sf) = 44.50 sf + waste factor (44.50 x 1.10) = 49 sf
The same method is used when measuring walls. Measure the area to be tiled on each wall. Add them together and figure the square footage. Add your waste factor and this is the amount needed.
Most vertical applications will require trim pieces which have finished edges, this requires a linear measurement. Trim pieces will be used:
1. Where a tiled surface ends on an open wall leaving an exposed tile edge,
2. Where a vertical surface meets a horizontal, like on the edge of a countertop,
3. Where a vertical surface turns a corner, like on the outside corner of a wall.
Trim pieces and decoratives are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6" bullnose, 8" decorative liner), then the rule is: Linear Inches/Piece Length = Quantity
