Syrus is 12 years old and has a younger sister, Samira, who is 6 years old. Syrus says, "Our ages are in a
proportional relationship because I am two times as old as my sister."
Is Syrus correct? Justify your answer.
Answers
Answer:
no
Step-by-step explanation:
that is because syrus's age only increases instead of 2 each year, so their ages wont stay in propotion for another year. samira will be 7 and syrus will be 13.
syrus age[] samira age
12 [] 7
13 [] 8
14 [] 9
15 []10
16 []11
17 []12

11. What is the RADIUS of ONE circle? Find the AREA of the figure.
Hint: (the circles are congruent)
Answers
Answer:
258.41 m
Step-by-step explanation:
Since there are three semi-circles in the length of the rectangle, we can divide 18 by 3 to get 6 as the diameter for each circle. The area of a semi-circle is (pi*r^2)/2, we can multiply that by 3 and add it with the area of the rectangle to get the total area.
(12*18) + (3(pi*3^2))/2 =
216 + 42.4115 =

The total surface area of triangular prism
A = 232 foot²
Step-by-step explanation:
Explanation:-
Given bases of prism 5 f t , 5 f t , 7 f t
The perimeter of the sum of the bases
P = 7 + 5 +5 = 17 f t
Lateral surface area =perimeter X height
= 1 7 × 8
= 136 f t²
Base area of the triangular prism = [tex]\frac{1}{2} h ( b_{1} + b_{2} ) = \frac{1}{2} 8 ( 5 +7) =48[/tex]
The total surface area of triangular prism
[tex]A = p h + 2 Base Area[/tex]
[tex]A = p h + 2 Base Area = 136 + 2 ( 4 8 ) = 232[/tex]
The total surface area of triangular prism
A = 232 foot²

Find the rate of change.
A): 1/63; The car travels 1 mile every 63 hours.
B): 10; The car travels 1 mile every 63 hours.
C): 63/1; The car travels 63 miles every 1 hour.
D): 252; The car travels 252 miles.
Answers
The answer is C)
The car travels 63 mph(Miles Per Hours).
252/4 = 63
378/6 = 63
504/8 = 63
630/10 = 63
Hope Helps you
The rate of change of traveling of the car is 63 miles every 1 hour.
Rate of changeA
Distance = 252 miles
Time = 4 hours
Average speed = Distance / time= 252 / 4
= 63 miles per hour
B
Distance = 378 miles
Time = 6 hours
Average speed = Distance / time= 378 / 6
= 63 miles per hour
C
Distance = 504 miles
Time = 8 hours
Average speed = Distance / time=504 / 8
= 63 miles per hour
D
Distance = 630 miles
Time = 10 hours
Average speed = Distance / time= 630/10
= 63 miles per hour
Therefore, the rate of change of traveling of the car is 63 miles every 1 hour

Given a = 31, A = 84 degrees, and b = 20, use the Law of Sines to solve for B. Round
your answer to the nearest degree, and enter the number only. Note: The figure is
not drawn to scale.
Answers
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
A = 84a = 31B = ?b = 20Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
