Step-by-step explanation:
Sam traveled 20 miles in 3 hours.
Sam walked part of the distance at a speed of 4 miles per hour.
Sam rode his bicycle for the remaining distance at a speed of 12 miles per hour.
note: this question has been asked before but i do not believe it was answered correctly, it was solved using 4 hours instead of 3
Answer:
see below
Step-by-step explanation:
distance / rate = time
x = walking distance 20 -x = biking distance
x / 4 m/hr + (20-x) / 12 m/hr = 3 hours
x/4 + ( 20-x) /12 = 3 multiply both sides of the equation by 12
3x + 20 -x = 36
2x = 16
x = 8 8 miles walking then 12 miles biking

Hello!
BC // AB => Thalès
AB/AC = AE/AD = BE/CD
3/(3+8) = AE/(AE+10)
3/11 = AE/(AE+10)
3/11 = AE/(AE+10)
3/11 * (AE+10) = AE/(AE+10) * (AE+10)
(3AE + 30)/11 = AE
(3AE + 30)/11 * 11 = AE * 11
3AE + 30 = 11AE
30 = 11AE - 3AE
30 = 8AE
AE = 30/8
AE = 3.75
AE ≈ 3.8

Answer:
x= 34
Step-by-step explanation:
96 + 50 + x = 180
180 - 146 = x
x= 34
Answer: x = 34
Step-by-step explanation:
The interior angles of a triangle add up to 180.
So we can set an equation to 180 like this: \(180 = x + 96 + 50\)
We can simplify this:
\(180 = x +146\)
Now we need to isolate x to solve for it.
We do this by subtracting the 146.
\(34 = x\)

4. Molly has 20 tomato plants to arrange in her garden. What are all the ways Molly can arrange the tomato plants in an array?
The number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways
Find the image attached. From the figure, we can see that there are 6 rows in the array.
If there are 20 tomato plants, the ways Molly can arrange the tomato plants in an array is expressed according to the permutation formula:
20P6 = 20!/(20-6)!
20P6 = 20!/14!
20P6 = 20 * 19 * 18 * 17 * 16 * 15
20P6 = 27,907,200
Hence the number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways

What are the answers to these questions?
Step-by-step explanation:
the inside expression of an absolute value expression can be positive or negative, but the result is only the positive one.
therefore, for our example here the negative case would be
2.5x - 6.8 = -12.9
which gives us
2.5x = -6.1
x = -6.1/2.5 = -2.44
and the positive case would be
2.5x - 6.8 = 12.9
and that gives us
2.5x = 19.7
x = 19.7/2.5 = 7.88

The coordinate of point R after the rotation is determined as = ( - 4, 7).
option A.
What is the rotation of a figure?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.
You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.
When a figure is rotated 180 degrees, each point of the figure is moved to a new position that is exactly opposite its original position with respect to a fixed center of rotation.
The initial coordinate of point R = ( 4, 7),
The new coordinate of point R after the rotation = ( - 4, 7)

Answer:
\(-\sqrt{2} + \sqrt{2}i\)
Step-by-step explanation:
Angle of 9pi/4
The equivalent angle of \(\frac{9\pi}{4}\), on the first lap, is found subtracting this angle from \(2\pi\). Thus:
\(\frac{9\pi}{4} - 2\pi = \frac{9\pi}{4} - \frac{8\pi}{4} = \frac{\pi}{4}\)
Thus, the sine and cosine are:
\(\sin{(\frac{9\pi}{4})} = \sin{(\frac{\pi}{4})} = \frac{\sqrt{2}}{2}\)
\(\cos{(\frac{9\pi}{4})} = \cos{(\frac{\pi}{4})} = \frac{\sqrt{2}}{2}\)
Angle of 3pi/2
On the first lap of the circle, thus no need to find the equivalent angle. We have that:
\(\sin{(\frac{3\pi}{2})} = -1, \cos{(\frac{3\pi}{2})} = 0\)
Expression:
\(4(\cos{(\frac{9\pi}{4})} + i\sin{(\frac{9\pi}{4})}) \div 2(\cos{(\frac{3\pi}{2})} + i\sin{(\frac{3\pi}{2})})\)
\(4(\frac{\sqrt{2}}{2} + i\frac{\sqrt{2}}{2}) \div 2(0 - i)\)
\(\frac{2\sqrt{2} + 2\sqrt{2}i}{-2i} \times \frac{i}{i}\)
Considering that \(i^2 = -1\)
\(\frac{-2\sqrt{2}+2\sqrt{2}i}{2}\)
\(-\sqrt{2} + \sqrt{2}i\)
One pound of blueberries costs $2.77 How many pounds of blueberries can you buy for $10? (Round to the nearest cent)
Answer:
Step-by-step explanation:
10 divided by 2.77 is
3.61010830325.
rounded up is 4 pounds?
Answer:
3
Step-by-step explanation:
If you divide 10 divided by 2.77 you get 3.610108303 but you don't need all the decimals so instead you will just get rid of the decimals in this scenario (not in all) and if you double check yourself by doing 2.77 x 3 you will get 8.31 and thats all you can do because 2.77 x 4 is 11.08 but you have a budget of $10.00 so your answer is:
You can get 3 pounds of blueberries with $10

Answer:
B) – 23 feet
Step-by-step explanation:
Given that the height of each story is 11½ feet, and that Stephen works two levels below ground.
The equivalent of two levels is: 11½ × 2 = 23 feet.
Since Stephen works two levels below ground, then that means that you must deduct two levels from the ground level (at 0 feet).
Ground level – two levels = 0 feet – 23 feet = – 23 feet
Therefore, the correct answer is B: – 23 feet
Please mark my answers as the Brainliest, if you find this helpful :)
Answer:
B. -23 feetStep-by-step explanation:
The height of two levels is:
2* 11 1/2 = 23 feetSince it is below the ground level, the elevation is negative.
So the answer is - 23 feet.

The owner of a bicycle store had a sale on bicycles (two-wheelers) and tricycles (three-wheelers). Each cycle had two pedals. When he counted the total number of pedals of the cycles, he got 50. When he counted the total number of wheels of the cycles, he got 64. Explain how you figured out how many tricycles were offered in the sale.
Let x represent number of bicycles and y represent number of tricycles.
We know that a bicycle has 2 pedals and a tricycle has 32 pedals as well.
We have been given that when the owner counted the total number of pedals of the cycles, he got 50. We can represent this information in an equation as:
\(2x+2y=50...(1)\)
\(2x=50-2y...(1)\)
We know that a bicycle has 2 wheels and a tricycle has 3 wheels.
We have been given that when the owner counted the total number of wheels of the cycles, he got 64. We can represent this information in an equation as:
\(2x+3y=64...(2)\)
Upon substituting equation (1) in equation (2), we will get:
\(50-2y+3y=64\)
\(50+y=64\)
\(50-50+y=64-50\)
\(y=14\)
Therefore, 14 tricycles were offered in the sale.
