Answer:
The answer is "
".
Step-by-step explanation:
Although the five first players are red, the very first five cards are not spaded as the spad is a black card.
Its chance of the final card mostly on deck being the ace of spades is therefore determined as:
Thus, here is the necessary chance.
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.

Answer:
Step-by-step explanation:
Let w represent the width. Then the length is 2w-5, and the perimeter is ...
P = 2(L+W)
44 = 2((2w-5) +w)
44 = 6w -10
54 = 6w
9 = w
2(9) -5 = 13 = length
The length of the rectangle is 13 meters; the width is 9 meters.
Answer:
<h2>174ft²</h2>
Step-by-step explanation:
Area of a Rectangle = L x W
L = 8
W = 6.5
Area of a Rectangle = 8 x 6.5 = 52
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 52 x 2 = 104
Area of a Rectangle = L x W
L = 8
W = 5
Area of a Rectangle = 8 x 5 = 40
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 40 x 1 = 40
Area of a Triangle = B x H x 1/2
B = 5
H= 6
Area of a Triangle = 5 x 6 x 1/2 = 15
Surface Area = Area of a Triangle x Number of Triangles
Surface Area = 15 x 2 = 30
Surface Area = Sum of Surface Areas =
104 + 40 + 30 = 174ft²
Answer:
B
Step-by-step explanation:
There are 2 operations happening on the left side to x.
1. x is being multiplied by -4.
2. 2/5 is being added to -4x.
If you had a number for x, and you wanted to evaluate the left side, first, you would multiply the value of x by -4. Then you would add 2/5.
To solve an equation or an inequality, you do the opposite operation in the opposite order.
Since the second operation was add 2/5, to solve, you start by doing the opposite of the second operation. That means you subtract 2/5 from both sides.
Answer: B
