Answer:
[tex] \approx 31.63 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of the figure = 2 times the area of one semicircle with radius (5/2 = 2.5) 2.5 ft + Area of triangle with base 6 ft and height 4 ft.
[tex] = 2 \times \frac{1}{2} \pi {r}^{2} + \frac{1}{2} bh \\ \\ = 3.14 \times {(2.5)}^{2} + \frac{1}{2} \times 6 \times 4 \\ \\ = 3.14 \times 6.25 + 3 \times 4 \\ \\ = 19.625 + 12 \\ \\ = 31.625 \\ \\ \approx 31.63 \: {ft}^{2} [/tex]

Which of the following numerical data sets has a mean of 40?
A) 18,82
B) 21, 34, 65
C) 38, 39, 40, 41
D) 20, 30, 40, 55
help!
Answer:
The answer is B) 21, 34, 65
Step-by-step explanation:
21 + 34 + 65 = 120
120 divided by 3 = 40.
In order to find the mean you must add up all of the numbers in the numerical data set, then divide that by how many numbers there are. Hope this helps! :)

The graph represents the distance in miles, y: that Car A travels in x minutes. The function y x represents the distance, y; that Car B travels in x minutes. Both cars are moving at a constant rate of speed. Which BEST compares the rates of the two cars? The rate of Car B is 1 of a mile per minute less than the rate of Car A 6 Bi The rate of Car A is of a mile per minute less than the rate of Car B. The rate of car B is 2 of a mile per minute greater than the rate of Car A. Car A and Car Bare traveling at the same rate per minute.
What’s the value of x
Answer:
x = 2
Step-by-step explanation:
According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)
m<L = (7x + 9)° is an inscribed angle
m(KM) = 46° is its intercepted arc
Therefore:
7x + 9 = ½(46)
Multiply both sides by 2
2(7x + 9) = 46
14x + 18 = 46
14x + 18 - 18 = 46 - 18
14x = 28
14x/14 = 28/14
x = 2
solve to find x 3/4 (5x-3) + 8 = 17
Answer:
3
Step-by-step explanation:
3/4 (5x -3)+8=17
3/4 (5x -3) = 17 - 8 = 9
(5x -3) = 9 * (4/3)= 36/3 = 12
5x = 12 + 3 = 15
x = 3

In the diagram shown,
PQRS is a rectangle,
XY is parallel to PS,
RY = 9 cm,
Area of PQRS = 84 cm,
Area of PXYS = 21 cm.
Work out the values of a and b.
You must show all your working.
9 cm
ү
bcm
P
S
Answer:
The answer is below
Step-by-step explanation:
PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm
The breadth of PQRS = a. Hence:
Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab
but Area of PQRS = 84 cm²
9a + ab = 84 (1)
In rectangle PXYS, length = QR = a cm, breadth = YS = b cm
Hence area of PXYS = length * breadth = (a)(b) = ab
But Area of PXYS = 21 cm²
ab = 21 (2)
substitute ab = 21 in equation 1:
9a + 21 = 84
9a = 84 - 21
9a = 63
a = 7 cm
ab = 21
7b = 21
b = 3 cm
Therefore a = 7cm, b = 3 cm

Jacob used a simulation to predict the chance that a canal will flood in 1 of the next 6 years. A number 1 indicates a year in which the canal will flood. Numbers 2, 3, or 4 indicate a year in which the canal will not flood. The results of the simulation are shown. What is the experimental probability that a canal will flood in at least 1 of the next 6 years?
here is the table and the question
Answer:
is there like answer choices or do you just fill it in? if so then i think it would be unlikely.
Step-by-step explanation:
there’s only 7 ones which is the number that shows it will flood so 7/36 is unlikely, it has to be more than half to be likely

The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds
Answer:
4 seconds
Step-by-step explanation:
fish broke the water's surface in 1 second and went back into the water at 5 seconds
∴ it was out of the water for 4 seconds

Whats the slope of the line?
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.
