he altitude to the hypotenuse of a triangle with angles of 30 and 60 degrees is 3 units. what is the area of the triangle, in square units? express your answer in simplest radical form.
The area of the triangle is 6√3 units.
How to the area of the triangle, in square units?given that the altitude to the hypotenuse of a triangle with angles of 30 and 60 degrees is 3 units.
The hypotenuse of a triangle with angles of 30°, 60°, and 90° is always twice as long as the side opposite the 30° angle, and it is almost three times as long as the side opposite the 60° angle.
so, let the shorter side of triangle is x.
the longer side of triangle is x√3.
the hypotenuse of the triangle is 2x.
now find the value of side of triangle
[tex]x \sqrt{3} = 3 \\ \frac{x \sqrt{3} }{ \sqrt{3} } = \frac{3}{ \sqrt{3} } \\ x = \frac{3 \sqrt{3} }{3} \\ x = \sqrt{3} [/tex]
so, the length of shorter side is √3 units.
now, find the value of hypotenuse of triangle
2x = 2√3
so, the length of hypotenuse of the triangle is 2√3 units.
now, find the base of the triangle
base = a√3 = (2√3) (√3) = 2(3) = 6
base = 6 units.
now, find the area of triangle
formula 1/2 (base)(height)
A = 1/2 (6) (2√3)
A = 6√3
Hence,the area of the triangle is 6√3 units.

11. Twenty-four students in Jamal's class are wearing tennis shoes. There are
thirty students in his class. Jamal says that 70% of his class is wearing
tennis shoes. Is Jamal correct? Explain your reasoning.
Answer: Incorrect.
Step-by-step explanation: 24 out of 30 is 80.00%.
Step 1: We make the assumption that 30 is 100 % since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100 % = 30.
Step 4: In the same vein, x % = 24 .
Step 5: This gives us a pair of simple equations:
100 % = 30(1).
x % = 24(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100 % / x % = 30/24
Step 7: Taking the inverse (or reciprocal) of both sides yields
x/100 = 24/30
x = 80 %

Step-by-step explanation:
t = number of t-shirts
n = number of notebooks
n + t = 70
5n + 11t = 500
n = 70 - t
5(70 - t) + 11t = 500

Find the coordinates of the missing endpoint if B is the midpoint of AC.
C(5/3,-6), B(8/3, 4)
The coordinates of the missing endpoint are (11 / 3, 14).
How to determine the location of the missing endpoint of a line segment
Herein we find the coordinates of a endpoint and a midpoint of a line segment and the location of missing endpoint can be found by using the midpoint formula, whose definition is shown:
B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y) (1)
If we know that B(x, y) = (8 / 3, 4) and C(x, y) = (5 / 3, - 6), then the location of the missing endpoint is:
(8 / 3, 4) = 0.5 · A(x, y) + 0.5 · (5 / 3, - 6)
(16 / 3, 8) = A(x, y) + (5 / 3, - 6)
A(x, y) = (16 / 3, 8) - (5 / 3, - 6)
A(x, y) = (11 / 3, 14)
The coordinates of the missing endpoint are (11 / 3, 14).

Step-by-step explanation:
Given graphed inequalities and a list of points, you want the point that is a "solution."
AssumptionsWe assume the graphed inequalities are part of a system of two inequalities and that a "solution" is one that must satisfy both of them. Any solution point will be in the doubly-shaded area, or on the solid blue boundary next to that area.
SolutionEach of the given points is 6 units from the origin on one of the coordinate axes. The only such point that lies in the doubly-shaded area is (-6, 0) on the negative x-axis.
The point (-6, 0) is a solution.
__
Additional comment
We know the kinds of inequalities that can give rise to a graph like this, but we don't know the question for which one of these points would be a solution. That is why assumptions are necessary.
The point (0, 6), for example, could be a solution to the question, "what set of values satisfies x-y ≤ 1, but not x+y < 3?"

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
We have to given the function is,
3 (x - 2) - 4 (x + 1) = -22
Now, We can solve the expression as,
3 (x - 2) - 4 (x + 1) = -22
Use Multiplicative property;
3x - 6 - 4x - 4 = -22
Use addition and subtraction property,
- x - 10 = - 22
Use addition property and Add 22 both sides;
- x - 10 + 22 = - 22 + 22
- x + 12 = 0
Use subtraction property, Subtract 12 both sides;
- x + 12 - 12 = 0 - 12
- x = - 12
Multiply by -1 in both sides,
x = 12
Therefore, The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,
⇒ x = 12

a truck rental company charges $90 plus $20 per hour. identify a function that represents the total charge for renting a truck for a certain number of hours. what is the value of the function for an input of 5, and what does it represent?
The function that represents the total charge for renting a truck for a certain number of hours is c(h) = $90 + $20(h) and the value of the function for an input of 5, is $190 and this represents the total charge for a rental of 5 hours.
Given,
A truck rental company charges $90 plus $20 per hour.
Here we need to identify a function that represents the total charge for renting a truck for a certain number of hours. And we also need to find the value of the function for an input of 5.
The problem statement tells you the total charge is the sum of $90 and a charge of $20 per hour. That is, for h hours, the total charge is ...
c = 90 + 20h
In functional form, this is
c(h) = 90 +20(h) . . . . . . total charger for a rental of h hours
The function value with an input of 5 is ...
c(5) = 90 +20(5)
c(5) = 90 + 100
c(5) = 290
Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 5 hours.
