Answer:
3/16
Step-by-step explanation:
2 <- 1 and 1(1/4*1/4=1/16)
3 <- 1 and 2,2 and 1(1/2*1/4=1/8)
4 <- 3/16
5 <- 4/16
6<-3/16
Answer:
$26.88
Step-by-step explanation:
Cost of a ply wood = $0.56 per square foot
If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:
8 * 6
= 48 sq. feet
Hence the area of 8 bird houses is 46sq. feet
Next is to calculate the amount it will cost to make the 8 bird houses.
Since 1 sq. foot = $0.56
48 sq. feet = y
cross multiply
y * 1 = 48 * 0.56
y = 26.88
Hence it will cost Dakota $26.88 to make hid bird houses
Step-by-step explanation:
<u>Complete the operation, find the quotient and match with correct option:</u>
- 44.1/4.9 = 9
- 32.8/8.2 = 4
- 43.2/3.6 = 12
- 161.2/5.2 = 31
- 93.6/7.2 = 13
Using the formula y = kx
80 = .5k
k = 160
y = 160*2.25
y = 360
Answer:
x = 9 ± √14
Step-by-step explanation:
x² − 18x + 67 = 0
Move the constant to the other side:
x² − 18x = -67
Take half of -18, square it, and add to both sides.
(-18/2)² = (-9)² = 81
x² − 18x + 81 = -67 + 81
x² − 18x + 81 = 14
Factor the perfect square:
(x − 9)² = 14
Solve for x:
x − 9 = ±√14
x = 9 ± √14
