1 answer:
malfutka [58]3 years ago

Answer:

503 m

Step-by-step explanation:

Let distance BC = Y

Height = X

tan(58) = X/Y

X = Ytan(58)

Y = X/tan(58)

tan(43) = X/(Y+225)

X = (Y+225)tan(43)

X/tan(43) = (X/tan(58) + 225)

X(1/tan(43) - 1/tan(58)) = 225

X(0.4474993581) = 225

X = 502.7940173

Which expressions are equivalent to 12 - 14/3t + 2/3t? Select ALL that apply. Please show how you got the answer.
geniusboy [140]

Answer:

B and F

Step-by-step explanation:

Equivalent expressions are expressions which in simplest form are equal. Simplify each expression to see each equals the simplest form of 12 - 14/3 t + 2/3 t.

12 - 14/3t + 2/3 t simplifies to 12 - 12/3t = 12 - 4t.

The options are:

a. 8t

b. 12-4t

c. -4(3 + t)  = -12 - 4t

d. 4(t - 3)  = 4t - 12

e. 12 - 16/3t

f. -4(t - 3) = -4t + 12

b and f are equivalent

Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged
Over [174]
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.

A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.

The dimensions of the original photo is 6 x 6.

How many permutations are possible for 13 objects taken 6 at a time?
Anarel [89]

Answer:

  1,235,520

Step-by-step explanation:

13P6 = 13!/(13-6)! = 13·12·11·10·9·8 = 1,235,520

__

There are 13 ways to choose the first object, 12 ways to choose the second, 11 ways to choose the third, and so on. The 6th object can be chosen 8 ways.

The total number of permutations is the product of all these ways:

  13·12·11·10·9·8 = 1,235,520
