Answer: 59.04

Step-by-step explanation:

tan 16= x/200

tan16/1=x/200  

200 tan 16=x  

x=57.349077...

x=57.349077...

Add 1.69, the distance from the ground to her eye:

57.349077...+1.69= 59.039077...

≈   The skyscraper is 59.04 meters tall.

candy that costs 31 cents per pound is mixed with candy that costs 46 cents per pound to obtain 50 pounds of candy that costs 40
photoshop1234 [79]

The amount of each type of candy (in pounds) that are mixed for the considered condition is: 20 pounds of first type of candy and 30 pounds of second type of candy.

<h3>How to form mathematical expression from the given description?</h3>

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we can assume the separate weights of each type of candies to be represented by variables.

Let we have:

  • x = weight (in pounds) of first type of candy whose cost is 31 cents per pound.
  • y = weight (in pounds)  of second type of candy whose cost is 46 cents per pound.

x pounds of first type of candy is mixed with y pounds of second candy.

The weight of the mixture = x + y = 50 pounds

The cost of the mixture = 40 cents per pound  = 40 \times 50 = 2000 cents

Cost of the mixture = cost of x pounds of first candy+ cost of y pounds of second candy = 31x + 46y
Thus, we get 31x + 46y =2000

Therefore, we got a system of two linear equations as:

x +y = 50\\31x + 46y =2000

From first equation, we get:

x = 50 -y

Substituting this value in second equation, we get:

31(50-y) + 46y =2000\\1550 + 15y = 2000\\15y = 450\\\\y = 450/15 = 30

Putting this value of y in equation for x, we get:

x = 50-y = 50-30 = 20

Thus, the amount of each type of candy (in pounds) that are mixed for the considered condition is: 20 pounds of first type of candy and 30 pounds of second type of candy.

What does b represent in the equation of a line in the form y = mx + b?
Dvinal [7]
B is called "the vertical intercept" and is the value of y when x = 0.  Something like an initial value!
