A and E
Step-by-step explanation:
The perimeter is the length of the edge of the overall shape. In this case, the edge includes the length of the curved section of both semicircles (since semicircles are the same size, we can just find the circumference for a circle with the same radius), plus four side lengths of the square.
The radius is 10 (Two squares line up exactly with the semi-circles).
Circumference: 2πr=2π10=20π
Perimeter =20π+4(10)=40+20π
A
40+20π=40+20π? YES
B
40+20π=80+20π? NO
C
40+20π=120+30π? NO
D
40+20π=300+100π? NO
E
40+20π=10+10+10π+10+10+10π? YES

The DeJeu family plan to drive to Marietta, GA to Newark, NJ. The distance is about 880 miles and the majority of their trip will be on a highway, where they will travel at an average speed of 65 miles per hour. They are leaving at 7:30 am, and they plan to stop 3 times for 10 minutes each and once for 1 hour. What is the approximate travel time?
Answers
Answer:
[tex]10:02:24\ \text{pm}[/tex]
Step-by-step explanation:
d = Distance to travel = 880 miles
s = Average speed of the car = 65 mph
Time taken to cover the distance is
[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}[/tex]
Time the car stopped
[tex]3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}[/tex]
Total time of the journey
[tex]13.54+1.5=15.04\ \text{hours}[/tex]
Converting [tex]0.04\ \text{hours}[/tex] to minutes
[tex]0.04\times 60=2.4[/tex]
So, the total time taken for the journey is [tex]15\ \text{hours and }2\ \text{minutes and }24\text{seconds}[/tex]
Time when they reach their destination
[tex]7:30+15:2.4\approx 10:02:24\ \text{pm}[/tex]

How do I find the area?
Answers
Answer:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square, you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Answer:
Base x Width x Height

Express your answer in L.
Answers
Answer: In 1 hour , it will waste = 1.25ml
Step-by-step explanation:
Volume of water wasted by the tap in 9 Hours = 11,250 ml
Since it drips in equal quantity,
In 1 hr , it will drip= 1 x 11,250 / 9 = 1,250 ml
But 1000 ml = 1 Liter
1250 ml = 1250ml x 1Liter / 1000ml= 1.25L

Answers
Answer:
a = 55
Step-by-step explanation:
By exterior angle theorem:
a+10 + 44 = 2a
a= 55
Here's the proof:
Consider the same figure shown
say a+10 = x and 44 = y
Thus the remainng angle is 180 - x-y
and the exterior angle is 180- ( 180 - x- y) = x+y
Thus proved

Answers
Answer:
-4 ≤ x ≤ 6
Step-by-step explanation:
When we talk of the domain, we are referring to the possible x-values
from the diagram, we can see that we have the x-values at -4 and 6
The dotted line means that -4 and 6 are in the domain
Thus, the two points represent the end and starting point of the domain
Writing this in interval notation, we have the representation as;

Answers
Answer:
6x - 18
Step-by-step explanation:
3 x 6 = 18, so thats how you get the 18 in the answer
3 x 2x = 6x, which is how you get the 6x
and theres a subraction sign so we know to put a - there.
Answer:
6x - 18
Step-by-step explanation:
3(2x - 6) =
("... - 6" means that whatever we do with the 6, we have to remember that it's negative)
3(2x - 6) =
3 * 2x + 3 * (-6) =
6x + (-18) =
(if we add a negative number then it's the same as subtracting that number)
6x + (-18) = 6x - 18
