Answer:
65 degrees
Step-by-step explanation:
The angles will sum up to 360, just do 360 - all known angles
360 - 90 - 128 - 77 = 65
Answer:
Step-by-step explanation:
Sum of all angles is 360 degrees
Let the measure of angle M equal x.
x+90+77+128=360
x=65
Measure of angle M is 65 degrees
Find the measure of x

Step-by-step explanation:
The values are plotted on the number line attached.

Each value is represented on the list both as a fraction and as a decimal. Equal values map to the same point on the number line.
0.27 = 27/100
0.49 = 49/100
0.75 = 75/100
The location on the number line is found by effectively dividing the distance between 0 and 1 into 100 parts, then locating the point on the corresponding division. The attached number line shows the interval divided into 50 parts, so the given values will lie halfway between the grid marks on this number line.

Which of the following numbers
could be the absolute value of
another number?
A -425
B 1,200
C -1,300
D-2,525
Answer:
Step-by-step explanation:
Essentially, recall what an absolute value function is.
When you plug number into an absolute value function, or make it an absolute value, you will ALWAYS get a positive version of that number.
When the question asks, what number could be the absolute value of another number, it's asking you what is a possible outcome of making a number an absolute value.
Since we know that making any number an absolute value, makes that number positive. We can get rid of all of the negative answers.
You are left with B.
Answer:
B. 1200
Step-by-step explanation:
Absolute value is the non-negative version of a number/variable. Whether the sign is negative or positive, the absolute value is always positive.
Example:
|-4|=4
|2|=2

A rectangular prism has a length of 20 meters, a height of 12 meters,
and a width of 12 meters. What is its volume, in cubic meters?
Answer:
2880 cubic meters.
Step-by-step explanation:
To find the area of a rectangular prism, multiply the length width and height.
20*12*12=144*20=2880
The volume of the Rectangular Prism is 2880 cubic meters.
What is Rectangular Prism?Rectangular prism can be defined as a" 3-dimensional solid shape which has six faces that are rectangles. A rectangular prism is also a cuboid".
According to the question,
Length of the rectangular prism = 20 meters
Height of the rectangular prism = 12 meters
Width of the rectangular prism = 12 meters
Formula for Rectangular Prism = length × breadth × height
= 20 × 12 × 12
= 2880 cubic meters.
Hence, the volume of the Rectangular Prism is 2880 cubic meters.

We can use the Taylor Polynomial expansion for a second-degree polynomial:
[tex]P_3(x) = g(c) + \frac{g'(c)}{1!}(x - c) + \frac{g''(c)}{2!}(x - c)^2[/tex]
Where c is the value that the polynomial is centered about.

Answer:
x = 44.5 due to the Triangle Angle Sum Theorem
Step-by-step explanation:
This is the Triangular Angle Sum Theorem.
This rule states that every angle inside the triangle has to equal 180.
This is a solve for x situation
2x + x + x + 2 = 180
Add all the x's first
3x + x + 2 = 180
4x + 2 = 180
Now subtract 2 both sides
4x = 180 -2
4x = 178
Divide 178 by 4
x = 44.5
You could verify by plugging 44.5 into the x's
2(44.5) + 44.5 + 44.5 + 2 = 180
89 + 44.5 + 46.5 = 180
Answer:
x = 44.5
Step-by-step explanation:
2x + x + (x+2) = 180
4x + 2 = 180
4x = 178
x = 44.5

Luka and Gabby rent a tandem bike for $25/hr.Which value is the dependent variable? Which is the independent variable? Write an equation to represent the relationship between the number of hours, h, and the total cost of c.
c = 25(h)
dependent variable : They must give $25 per hour.
independent variable: time is independent as no specific time given.
total cost = $25 * hours taken
c = 25 * h
c = 25(h)
Answer:
See below ↓
Step-by-step explanation:
Given
rate of renting a tandem bike = $25/hh = number of hoursc = total costSolving
Clearly, as the number of hours does not depend on another variable, h is the independent variableTherefore, c is the dependent variableThe equation is :⇒ c = 25hWhat is the slope-intercept equation for this line?
