Complete Question
Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?
a) She cut the wood into pieces that are each 1/3 meter long.
b) She cut the wood into pieces that are each 1/2 meter long.
c) She cut the wood into pieces that are each 1 meter long.
d) She cut the wood into pieces that are each 1 1/2 meter long.
Answer:
d) She cut the wood into pieces that are each 1 1/2 meter long.
Step-by-step explanation:
Marla sawed a 12-meter wood plank into 8 equal pieces.
Hence,
8 equal pieces = 12 meter
1 equal pieces = x meter
Cross Multiply
8 × x = 1 × 12
x = 12/8 meters
x = 3/2 meters long
x = 1 1/2 meters long.
Therefore, Option d is the correct Option
Answer:
24.4
Step-by-step explanation:
18 ÷ 2 = 9
26² = x² + 9²
x² + 81 = 676
x² = 676 - 81
x² = 595
x = √595
x ≈ 24.4

2(3x-1) ≥ 4x-6
Distribute the 2 on the left side: 6x-2 ≥ 4x-6
Move terms to solve for x:
2x ≥ -4
x ≥ -2
Therefore, any value from -2 to ∞ are valid solutions.
Answer:
A1 / B1 ;
(D1 - A1) / B1 ;
(A1 - E1*A1) / B1
Step-by-step explanation:
A1 = original price of car
B1 = annual Depreciation amount
Number of years it will take for the car to depreciate totally :
Using the straight line Depreciation relation :
y = mx + c
c = intercept = initial or original value of car
m = annual Depreciation amount
x = number of years
y = value after x years
For total Depreciation, final value, y = 0
0 = mx + c
mx = - c
x = - c / m
Hence, x = A1 / B1
B.)
D1 = car value
Length it will take for car to depreciate to value in D1 :
y = mx + c
y = D1; m = B1 ; c = A1
D1 = B1x + A1
B1x = D1 - A1
x = (D1 - A1) / B1
C.)
E1 = decrease percentage
Time it takes for car to decrease by percentage in E1
y = E1 * A1
E1 * A1 = B1x + A1
(A1 - E1*A1) = B1x
x = (A1 - E1*A1) / B1
Answer:
2 - 4
