Answer:

43.46 feet

Step-by-step explanation:

tan 41 = 50 ÷ the distance from the base (x)
cross multiple
tan 41 × x = 50
divide both side with tan 41
x = 50÷ tan 41
x = 43.46 feet

Part 1 out of 2 Select the real-world problem best represented by the equation 15x = 570. A An elephant walks with a speed of 15

nika2105 [10]

Answer:

Option A.

Step-by-step explanation:

We will check each option given in the question.

Option A. If an elephant walks with the speed = 15 steps a minute

If it takes x hours to cover 570 steps then the expression should be

15x = 570

Therefore, Option A. will be the answer.

Option B. A giraffe eats leaves = 570 per hour

If it eats for 15 hours then number of leaves eaten by giraffe = 570×15

So the expression is not formed.

Therefore, Option B is not the answer.

Option C. Dandelions eaten by the donkey = 15

and dandelions eaten by cow = 570

So total dandelions eaten by cow and donkey together = 15 + 570

Again the expression is different so Option C is incorrect

Option D. A Canary flew for 15 hours towards north, then turned east and flew for 38 hours.

Here speed of the canary is not mentioned so it's not possible to form any expression for the distance covered by the canary.

Therefore, Option D is also incorrect.

Option A. is the answer.

What is the solution to the equation below?

12345 [234]

Answer:

C x=6

Step-by-step explanation:

sqrt(x+3) = x-3

Square each side

(sqrt(x+3))^2 = (x-3)^2

x+3 = (x-3)^2

x+3 = (x-3)(x-3)

FOIL

x+3 = x^2 -3x-3x+9

Combine like terms

x+3 = x^2 -6x+9

Subtract x from each side

x-x+3 = x^2 -6x-x +9

3 = x^2 -7x +9

Subtract 3 from each side

3-3 = x^2 -7x +9-3

0 = x^2 -7x+6

Factor

0 = (x-6)(x-1)

Using the zero product property

x-6=0 x-1 =0

x=6 x=1

Since we squared we need to check for extraneous solutions

x=1

sqrt(1+3) = 1-3

sqrt(4) = -2

2=-2

False

Extraneous

x=6

sqrt(6+3) = 6-3

sqrt(9) = 3

3=3

True solutions

The average number of red blue and green bags is 136. They are 30 more red than blue bags. There are 15 less green than blue. Ho

Andrews [41]

Answer:

The Number of green bag is 116

Step-by-step explanation:

Given as :

The average number of red , blue and green bags = 136

I.e $\frac{red + blue + green}{3}$ = 136

Or, red + blue + green = 136 × 3

Or, red + blue + green = 408

Number of red bag = Number of blue bags + 30

Number of green bag = Number of blue bags - 15

Or, ( blue bag + 30 ) + blue bag + ( blue bag - 15 ) = 408

Or, 3 blue bag = 408 - 15

Or, Number of blue bags = 131

Number of red bag = Number of blue bags + 30

Number of red bag = 131 + 30

Or, Number of red bag = 161

Number of green bag = Number of blue bags - 15

Or, Number of green bag = 131 - 15

Or, Number of green bag = 116

Hence The Number of green bag is 116 Answer
