Answer:
3610 dollars
Step-by-step explanation:
Remark
If you take the Cube Root of the volume, that will give you the length of an edge of the cube. If you square the edge, you get the area of one of the faces of the cube.
The Cost = the Area of 1 face * 10 dollars. is the answer.
Given
Volume = 6859 cubic feet
Cost per square foot = 10 dollars.
Solution
V = 6859 feet^3 Take the cube root of both sides
Edge = ∛V
Edge = ∛V = ∛6859
Edge = 19 feet exactly.
Area of the floor = s^2
Area of the floor = 19^2
Area of the floor = 361 square feet
Cost = 10 * 361 = $3610
Answer:
Margaret has 2 flowers
Step-by-step explanation:
First we can make a set of equations
j = 3m
a = 3j
a + j + m = 26
Since j = 3m we can rewrite Anna's equation as a = (3(3m)) or simply a = 9m
Now we can plug in the equations for Anna and Jessica into the main equation
9m + 3m + m = 26
13m = 26
m = 2
Answer:
Area of play ground = Length × Breadth = 750 × 250 = 187500. a Cost of levelling the ground = 187500 × 16 100 = Rs . 30000
X = 12400
20/100 = 1/5
2480 x 5 = 12400
Answer:
$2147.36
Step-by-step explanation:
The first value can be modeled by ...
b1 = 1000·(1 -0.005)^t
After 10 years, that balance is ...
b1 = 1000·0.995^10 = 951.11
__
The second value can be modeled by ...
b2 = 1000·(1 +0.018/2)^(2t)
After 10 years, that balance is ...
b2 = 1000·1.009^20 = 1196.25
__
The total of the two investments after 10 years is ...
$951.11 +1196.25 = $2147.36
