Solve for B.<br> 15B +9C =6

A private school opened in 2005 with an initial enrollment of 85 students. The enrollment has increased by an average of 18 stud

<span>1. Let t = time in years, with t = 0 representing the year 2005. Let f(t) = the number of students enrolled at the private school and g(t) = the number of students enrolled at the public school. Create the two functions to represent the situation.

f(t) = 85 + 18t </span>⇒ y = 85 + 18x<span>
g(t) = 95 + 15t </span>⇒ y = 95 + 15x

y = y
85 + 18x = 95 + 15x
18x - 15x = 95 - 85
3x = 10
x = 10/3
x = 3 1/3

y = 85 +18(10/3) = 85 + 180/3 = 85 + 60 = 145
y = 95 + 15(10/3) = 95 + 150/3 = 95 + 50 = 145

x = 10/3 or 3 1/3
y = 145

URGENT

Ivan

This is a question of proportions:

First we can work out how many feet it goes up for each feet he steps back:

5.5/6 ft per each feet he steps back.

Now we can multiply this by the amount of ft back the cliff is:

(5.5/6)*30 = 27.5 ft

Thus the cliff is 27.5 ft tall,

Hope this helps :)

19. In the triangle ABC, the side lengths are BC = 14 and AC = 7. What's the angle measurement of B?

mr Goodwill [35]

Answer:

Is not possible to compute the angle under those conditions.

Step-by-step explanation:

You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.

Let ΔABC and ΔDEF be two triangles where AB = DE and AC = DF if

∠A > ∠D then BC > EF, which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.

Therefore, there is information missing in order to solve the question

The equivalent expression to given expression is 1/3.

<h3>What is Equivalent Expression?</h3>

Equivalent expressions are defined as algebraic expressions which give the same resulting expression. An algebraic expression (or) a variable expression is defined as a combination of terms by the operations such as addition, subtraction, multiplication, division.

Here, given expression

$\sqrt{2/x^2} X \sqrt{x^2/18}$
