An adult has a total of about 21.4 square feet (ft2) of skin. Use the fact that 1 m is approximately equal to 3.281 feet to convert this measurement to square meters (m2).
Answer:
1.99m²
Step-by-step explanation:
From the above question
1 ft = 3.281 m
1 ft² = (3.281 m)²
Converting 21.4 ft² to m²
1 ft² = (3.281 m)²
21.4 ft² = xm²
x m² = 21.4 ft²/ (3.281 m)²
x m² = 1.9879310292 m²
Approximately :
21.4 ft² = 1.99m²

A company that makes robotic vacuums claims that their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. The consumer group plans to test the hypotheses H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model. Are the conditions for inference met?
No, the random condition is not met.
No, the 10% condition is not met.
No, the Normal/large sample condition is not met.
Yes, all conditions for inference are met.

The height (in feet) of objects launched from a
pirate ship's rocket launcher can be modeled by
the equation h = -16t? + 180t + 18 where t is the
time in seconds.
*Find the maximum height a launched item
could reach. (Round to two decimal places).
*After how many seconds will an item hit the
water after being launched? (Round to nearest
whole number).
Please someone help me
Answer:
i) 524.25feet
ii) 11secs
Step-by-step explanation:
1) Given the height of the rocket modelled by the equation
h = -16t² + 180t + 18 where
t is in seconds
At the maximum height, the velocity of the object is zero.
v(t) = dh/dt = 0
dt/dt = -32t + 180
0 = -32t + 180
32t = 180
t = 180/32
t = 5.625secs
Get the maximum height
h = -16t² + 180t + 18
h = -16(5.625)² + 180(5.625) + 18
h = -16(31.640625)+ 180(5.625) + 18
h = -506.25+1,012.5+18
h = 524.25feet
Hence the maximum height a launched item could reach is 524.25feet
ii) The item will hit the water at h = 0
Substitute inti the expression
h = -16t² + 180t + 18
0 = -16t² + 180t + 18
16t² - 180t - 18 = 0
Divide through by 2
8t² - 90t - 9 = 0
t = 90±√90²-4(8)(-9)/2(8)
t = 90±√8100+288/16
t = 90±√8,388/16
t = 90±91.586/16
t = 90+91.586/16
t = 181.586/16
t = 11.35sec
Hence the item hit the water after 11secs (to nearest whole number)

The green parallelogram is a dilation of the black parallelogram. What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3
=============================================================
Explanation:
"The green parallelogram is a dilation of the black parallelogram"
This tells us that the preimage is the black parallelogram and the image is the green one.
In short, the mapping is [tex]\text{black} \to \text{green}[/tex]
The image is smaller than the preimage (green is smaller than black), indicating the scale factor is some value of k such that 0 < k < 1. We can rule out choices C and D because of this.
--------------------
Measuring along the top, we can see that the black parallelogram goes from x = -6 to x = 8. Check out the image shown below where I've marked your given diagram, adding on helpful lines to show this going on.
The number-line distance from x = -6 to x = 8 is 14 units, so the top side of the black parallelogram is 14 units long.
The corresponding top side of the green parallelogram is 7 units long (because it spans from x = -3 and x = 4; as shown in blue in the figure below).
Divide the image length over its corresponding preimage length to get the scale factor.
scale factor = (image length)/(preimage length)
scale factor = 7/14
scale factor = 1/2
which points to choice B as our final answer.

In what ratio must 40m3 be decreased to become 24m3?
Answer:
40m3 must be decreased by 40% to become 24m3.
Step-by-step explanation:
To determine in what ratio must 40m3 be decreased to become 24m3, the following calculation must be performed:
40 = 100
24 = X
24 x 100/40 = X
2400/40 = X
60 = X
100 - 60 = 40
Therefore, 40m3 must be decreased by 40% to become 24m3.
