Question 1: Use your knowledge of angle relationships to solve for b.
*
30°
b
Answer:
c. b = 60 degrees
Step-by-step explanation:
Complementary angles, when you add them together, they give 90°. Therefore,
b + 30° = 90°
Solve for b. Subtract 30 from each side
b + 30° - 30° = 90° - 30°
b = 60°

Answer:
48°60°72°Step-by-step explanation:
The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:
4×12° : 5×12° : 6×12° = 48° : 60° : 72°
Angles 1 to 3 are 48°, 60°, 72°, respectively.

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10/?
Quadratic formula: * = -bt/b? 40c

O x=5+31
O x = 51/19
O x = 5+219
O x = 5+2/31
Answer:
[tex]x = 5 \± \sqrt{31}[/tex]
Step-by-step explanation:
Given
[tex]6 = x^2 - 10x[/tex]
Required
The solution in radical form
[tex]6 = x^2 - 10x[/tex]
Rewrite as:
[tex]x^2 - 10x - 6 = 0[/tex]
Using the quadratic formula, we have:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
a = 1
b = -10
c = -6
So, we have:
[tex]x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{100 +24}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{124}}{2}[/tex]
Split the roots
[tex]x = \frac{10 \± \sqrt{4 * 31}}{2}[/tex]
Express [tex]\sqrt 4[/tex] as 2
[tex]x = \frac{10 \± 2\sqrt{31}}{2}[/tex]
Split the fraction
[tex]x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}[/tex]
[tex]x = 5 \± \sqrt{31}[/tex]

A clown weighs 60 lb more than a trapeze artist. The trapeze artist weighs two-thirds as much as the clown. How much does each weigh?
Answer:
Step-by-step explanation:
well if the clown weighs 60 lbs more than the trapeze artist...
and the trapeze artist is 2/3 the weight of the clown...
then the trapeze artist must weigh 120 lbs..
and the clown must weigh 180 lbs..

Enter an equation of the form y= mx for the line that passes through the
origin and has slope 13.
Answer:
y = 13x
Step-by-step explanation:
gradient = 13
x = 0
y = 0
[tex]\frac{Δy}{Δx}[/tex]
so [tex]\frac{y - 0}{x - 0}[/tex] = 13
cross multiply and you get
y = 13x
Which of the following equations describes the line shown below? Check all
that apply.
(1, 13)
10
(-2, 4)
X
- 10
10
-10-
Answer: A&D
Step-by-step explanation:
because the first point is (x is 1,y is 13) and it fits with what your given then you move on to the next problem is (x is -2, y is 4) and it fits with what your given.
All your doing is finding the same point

Susanne is going to college and was informed that she will get a grant to pay for
her tuition. Which statement describes a grant?
Answer:
what are the options????
what is the range of f?
Answer:
Range is [tex]-5 \le y \le 5[/tex]
Range in interval notation is [-5, 5]
==========================================================
Explanation:
Refer to the diagram below. As marked in red, the smallest y value is y = -5. The largest y value is y = 5. The range is the set of y values between these endpoints, including both endpoints.
We can say the range is [tex]-5 \le y \le 5[/tex]
In interval notation, we write that as [-5, 5]. The use of square brackets tells the reader that the endpoints are included as part of the range.

The following estimated regression equation was developed for a model involving two independent variables.
ŷ =40.7+8.63x1+2.71x^2
After x2 was dropped from the model, the least squares method was used to obtain an estimated regression equation involving only x1 as an independent variable.
ŷ= 42.0+9.01x1
Required:
a. Give an interpretation of the coefficient of x1 in both models.
b. Could multicollinearity explain why the coefficient of x1 differs in the two models? If so, how?
Answer:
(a): y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second
(b): Yes
Step-by-step explanation:
Given
[tex]\wedge y = 40.7 + 8.63x_1 +2.71x_1[/tex]
[tex]\wedge y = 42.0 + 9.01x_1[/tex]
Solving (a): An interpretation of x1 coefficient
We have the coefficients of x1 to be 8.63 and 9.01
Literally, the coefficient represents the average change of y-variable per unit increase of the dependent variable
Since the coefficients of x1 in both equations are positive, then that represents an increment on the y variable.
So, the interpretation is:
y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second
Solving (b): Multicollinearity
This could be the cause because x1 and x2 are related and as a result, x2 could take a part of the coefficient of x2
The area of a triangle is 150 in2. If the height is 20 inches, find the
length of the base.
Answer: The base of the triangle is 15 inches
Formula for area of a triangle: A = bh/2
Subsitute values into the formula:
150 = b(20)/2
Now solve for b
150 = b20/2
x 2 x2
--------------------
300 = b20
300/20 = b20/20
15 = b
The base of the triangle is 15 inches
4/5 of the senior class went to prom if 324 seniors went to prom how many are there in the senior class
Answer:
405
Step-by-step explanation:
324 seniors is 4/5 of all seniors. To find how many 5/5 of the seniors is, we find 1/5 and multiply it by 5. Since 4/5 is 4 times 1/5, divide 324 by 4. The answer is 81, which is 1/5 of the seniors. Multiply 81 by 5 to get all 5/5. 81 * 5 is 405
