Answer:

correct question
Charles drew a regular hexagon and divided it into two identical trapezoid , the side length of the hexagon iscoming16cm,the diagonal shown in fig 30 is 32 cm Charles measure the height of one the trapezoid and found that the height was 13.9 cm find the area of the area
Step-by-step explanation:
The side length of the hexagon should be given which is 16 cm
To get the Length the side length makes with the height of the trapezium, Pythagoras theorem is applied to get the base of the triangle
Base = √((16)^2 - (13.9)^2
Base = √62.29
Base = 7.92cm
Since we have gotten the base
Diagonal - the base gives the top length of the trapezium.
32- 7.92- 7.92 = 16.16
The area of the hexagon gives the 2 times of the trapezium.
To find the area of the trapezium
= 1/2 * ( a+b)h
= 1/2* ( 32+ 16.16)* 13.9
= 24.04*13.9
Area of the trapezium = 334.71cm2
= 334.71 * 2
= 669.42cm2

A storage trunk is shaped like a rectangular prism. The trunk's volume is 18 cubic feet. The length of the trunk is 6 feet, and the width of the trunk is 2 feet. What is the height of this trunk
Answers
Answer:
1.5
Step-by-step explanation:
The height is 1.5 because to find the volume of a rectangular prism, you do length x width x height. Without height, you multiply length x width (6x2) and divide that by the volume (18 divided by 12 = 1.5)

You are playing blackjack and want to know the probability of getting dealt certain cards. In blackjack two cards are drawn from a deck, the first is dealt to you face down and the second is dealt face up. Using the product rule, find the probability that (a) The bottom card is an ace or a king and the top card is red. (b) Both of the cards are clubs. (c) At least one of the cards is a jack.
Answers
Answer:
The correct answer is:
(a) 0.0784
(b) 0.0588
(c) 0.1493
Step-by-step explanation:
According to the question,
Number or ace or king,
n (ace or king) = 8
Number of red,
n (red) = 26
Number of club,
n (club) = 13
Number or jack,
n (jack) = 4
(a)
Probability of 1st ace or king and 2nd in red will be:
⇒ [tex]P(ist \ ace \ or \ king \ and \ 2nd \ red) = \frac{8}{52}\times\frac{26}{51}[/tex]
⇒ [tex]=0.0784[/tex]
(b)
Probability of both clubs will be:
⇒ [tex]P(clubs) =\frac{13C_2}{52C_2}[/tex]
⇒ [tex]=0.0588[/tex]
(c)
Probability of at least one is jack will be:
⇒ [tex]P(at \ least \ one \ is \ jack)=1-P(none \ jack)[/tex]
⇒ [tex]=1-\frac{48C_2}{52C_2}[/tex]
⇒ [tex]=0.1493[/tex]
Find the circumference and the area of a circle
with the dimensions listed. Use the value 3.14 for π
,and do not round your answers. Be sure to
include the correct units in your answers.
a) diameter of 3 cm
b) radius of 5 ft
Answers
In response to the question, we may say that As a result, the radius of the circle is 9.42 cm and its area is 7.065 cm sq
What is circle?A circle seems to be a two-dimensional component that is defined as the collection of all places in a jet that are equidistant from the hub. A circle is typically shown with a capital "O" for the centre and a lower portion "r" for the radius, which represents the distance from the origin to any point on the circle. The formula 2r gives the girth (the distance from the centre of the circle), where (pi) is a proportionality constant about equal to 3.14159. The formula r2 computes the circumference of a circle, which relates to the amount of space inside the circle.
a) 3 cm diameter: The radius (r) of a circle is half its diameter, hence r = 3 cm/2 = 1.5 cm
The formula C = 2r gives the circumference of a circle, where is approximately equivalent to 3.14.
As a result, C = 2 3.14 1.5 cm = 9.42 cm.
The formula A = r2 calculates the area of a circle.
As a result, A = 3.14 (1.5 cm)2 = 7.065 cm sq.
As a result, the radius of the circle is 9.42 cm and its area is 7.065 cm sq

Calculate number of FTE needed to be hired to cover additional procedures per 7.5 hour day
Answers
Answer:
The number of FTE needed to be hired to cover the additional procedures per 7.5 day work is:
= 1.
Step-by-step explanation:
a) Data and Calculations:
Endoscopies EP Studies Total
Projected number of studies 60 5 65
Time in minutes for per study 5 15
Total time required (in minutes) 300 75 375
Full-time Employee (FTE) works 7.5-hour day or 450 minutes (7.5 * 60) per day.
b)The number of full-time employees (FTE) needed to be hired to cover the additional procedures per 7.5-day work is 1. The FTE has 450 minutes available for the additional procedures. She will only require 375 minutes. Therefore, she has extra (idle) time of 75 (450 - 375) minutes per workday.

an object is launched at 4 ft./s from 88 foot tall platform the objects height H in feet after T seconds is given by the equation H=-16T^2+8t+80 when does the object strike the ground
Answers
Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds

One earthquake has a MMS magnitude 4.1. If a second earthquake has 540 times as much energy as the first, find the magnitude of the second quake.
Answers
Answer:
This is not the case. Instead, use the equation M = 2/3log(S/S 0), where M is the amplitude of the first earthquake and S is the seismic moment. In this instance... 2/3log(S/S 0) = 3.3 log(S/S 0) = 3.3(2/3) log(S S 0) = 4.95 ten S = 10 = 4.95 = S/S 0 4.95*S 0*S 0*S 0*S 0* 610*104.95*S 0 = S 2/3log((610*104.95*S 0)/S 0) M M = 2/3log(60*104.95) M = 2/3log(60*104.95) M = 2/3log(60 5.156887 M = 5.156887 M = 5.156887 M = 5. As a result, the magnitude of the second quake is 5.156887.

A cook places two thirds of a pound of garlic powder in a plastic container. This occupies one third of the space in the container. How much pounds of a powder can be stored in this container?
Answers
Answer:
1
Step-by-step explanation:
Add e
Number of pounds of a powder that can be stored in the container is 2 pounds.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator.
Given that,
Number of pounds of garlic powder placed in container = 2/3 pound
This is equal to one third of the total space in the container.
So, we can write this as,
Number of pounds of powder in 1/3 space = 2/3 pounds
Number of pounds of powder in 1 full space = 2/3 ÷ 1/3
= 2/3 × 3 (by reciprocal rule)
= 2 pounds
Hence 2 pounds can be stored in the full container.

How many miles did Byron drive? Please do not guess!
Answers
=======================================================
Explanation:
The distance from his house to the gas station is 5 miles. We can find this by counting out the number of spaces between the two points (since the chart indicates that 1 unit = 1 mile). Or we can subtract the x coordinates to get 8-3 = 5. This only works because the y coordinates of each point are the same value.
To find the distance from the gas station to the market, we subtract the y coordinates this time. This only works due to the x coordinates being the same. We get a distance of 8-3 = 5 miles.
Overall, the total distance Byron drives is 5+5 = 10 miles.

Answer/Step-by-step explanation:
3. Volume = l*w*h = 1*3*1 = 3 ft³
Surface area = 2(lw + wh + lh) = 2(1*3 + 3*1 + 1*1) = 14 ft²
4. V = 216 cm³
w = 6 cm
l = 12 cm
h = ?
V = l*w*h
Plug in the given values and find h
216 = 12*6*h
216 = 72*h
216/72 = h
h = 3
Surface area = 2(lw + wh + lh)
= 2(12*6 + 6*3 + 12*3) = 252 cm²
5. V = 120 m³
h = 4 m
l = 5 m
w = ?
V = lwh
Plug in the given values
120 = 5*w*4
120 = 20*w
120/20 = w
w = 6 m
Surface area = 2(lw + wh + lh)
= 2(5*6 + 6*4 + 5*4)
= 148 m²
6. V = 726 in³
h = 11 in
w = 33 in.
l = ?
V = lwh
Plug in the values
726 = l*33*11
726 = l*363
726/363 = l
l = 2 in
Surface area = 2(lw + wh + lh)
= 2(2*33 + 33*11 + 2*11)
= 902 in²
