Answer:
400x
Step-by-step explanation:
in standard form is 400x
Answer:
Equation is;
(D/8) + (D/4) = 1600
D = 4266.67 ft
Step-by-step explanation:
We are told that the bee flies at a rate of 8ft/sec directly to a flowerbed from its hive. Thus,
speed during this stage is; v1 = 8ft/sec
Time during this stage is; t1
The bee stays at the flower bed for 1200 seconds.
Thus, time at this stage is; t2 = 1200 s
It flies directly back to the hive at 4ft/sec.
Speed at this stage; v2 = 4 ft/s
Time at this stage; t3
We are told that it was away for a total of 2800 seconds.
Thus; t1 + t2 + t3 = 2800
Since t2 = 1200 s, then;
t1 + 1200 + t3 = 2800
t1 + t3 = 2800 - 1200
t1 + t3 = 1600
Now, during time t1, the speed was 8ft/sec, since distance is equal to speed × time, then we have;
D = 8t1
t1 = D/8
During time t3, the speed was 4ft/sec. Thus; D = 4t3
t3 = D/4
Thus,since t1 + t3 = 1600
Then;
(D/8) + (D/4) = 1600
Multiply through by 8 to get;
D + 2D = 1600 × 8
3D = 12800
D = 12800/3
D = 4266.67 ft
Answer:
A= 10 units squared
Step-by-step explanation:
Because we are fully given points A and B, as well as the knowledge that ABC is a right triangle, we can assume that point C is the last needed point to form the right angle of this triangle. Meaning, point c has to have <em>one</em> identical coordinate out of (x,y) that is the same from <em>each</em> of our pre-existing coordinates in order to successfully form a right angle.
Due to the fact that we are told that Point C lies on y=2, we know that it already has an identical 'y' coordinate as Point A.
We can now decode that the x coordinate of Point C must be identical to the x coordinate of Point B, In this case, -2
We can conclude that point C lies on (-2,2)
If we look at the length of the sides of the triangle, ignoring the hypotenuse, we can see that one is 4 units long and the other is 5 units long.
To find the area of a square the formula is A= l x w x 0.5
Since 4x 5 = 20 and half of 20 is ten, we know that the final answer will be 10 units^2

Answer:
1.222x10^38
Step-by-step explanation:
there are 35 0's in the number
V=(hπr^2)/3, we are given that h=2.5in, r=5, and π≈3.14 so:
V=(2.5*25*3.14)/3
V≈196.25/3 in^3
V≈65.42 in^3 (to nearest hundredth of a cubic inch)
