Garden A has area 25 square meters. Garden B has area 58.7 square meters. The area of garden B is what percent of the area of garden A? First round the area of garden B to the nearest 10 square meters estamate the answer
Answer: The area of garden B is 234.8% of the area of garden A.
Step-by-step explanation:
Given: Garden A has area 25 square meters. Garden B has area 58.7 square meters.
The percent of the area of garden A is the area of garden B =
[tex]\dfrac{\text{area of garden B}}{\text{area of garden A}}\times100[/tex]
[tex]=\dfrac{58.7}{25}\times100\%\\\\= 58.7\times4\%\\\\= 234.8\%[/tex]
Hence, the area of garden B is 234.8% of the area of garden A.

The bells are adding a new room to their house. The room will be a cube with volume 8,000 ft^3. They are going to put in hardwood floors, and the contractor charges $10 per square foot. How much will the hardwood floors cost?
Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge
Hence,
a³ = 8000
Take the cube root of both sides
a = 20
Hence,
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000

Step-by-step explanation:
Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?
Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.

A powerful computer costs $1500, but on average, it loses 20% of its value each year. How much will it be worth 4 years from now
step by step please
Answer:
0.2%
Step-by-step explanation:
well if the computer is 100% value and within 4 years it loses 20% a year you would have to take the 100% and then 20% x 4 is 80% which would lead to 0.2%
is 0.058 more or less than 0.58
Answer:
Less.
Step-by-step explanation:
The way decimals and numbers in general work, each number to the right becomes 10 times less than the one before. Therefore, adding a 0 BEFORE the numbers would make 0.058 10 times less than 0.58.

The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).
