which of the following are valid names for the given triangle ? check all that apply
Answers
Answer: B. ΔMLZ
D. ΔLMZ
E. ΔZML
Step-by-step explanation:
In the given picture we have one triangle with three vertices as
Vertex L
Vertex M
Vertex Z
To name a triangle we use the labels of the vertices of the triangle, which are commonly written in capital letters.
When we name a triangle, we can start with any vertex but we need to keep the letters in order as you go around the triangle.
Therefore, the possible names of the triangle are :-
ΔLMZ Δ LZM ΔMLZ ΔMZL ΔZLM ΔZML

What is the rate of change for the relationship represented in the graph? (1 point)
A. 1/15
B.1/14
C.14
D.15
Answers
You can find the rate of change by taking any two points from your graph and plugging them into the following equation:
[tex] \frac{y_2-y_1}{x_2-x_1} [/tex]
Let's use the first two points you're shown from least to greatest. These are (0, 0) and (1, 15).
Now, identify what number is which and plug them into your equation. The solution will be your rate of change.
[tex]y_2 = 15 \\ y_1 = 0 \\ x_2 = 1 \\ x_1 = 0[/tex]
[tex]\frac{15-0}{1-0}[/tex]
[tex] \frac{15}{1} [/tex]
[tex]15[/tex]
15, or D, will be your answer.
Hope this helped you out! :-)
The rate of change for the relationship represented in the graph is 15
What is rate of change?The rate of change of a linear graph is the slope of the graph
From the graph, we have the following ordered pairs
(x,y) = (0,0) and (2,30)
So, the rate of change (m) is then calculated as:
[tex]m =\frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]m =\frac{30 - 0}{2 - 0}[/tex]
Evaluate the differences
[tex]m =\frac{30 }{2 }[/tex]
Evaluate the difference
[tex]m=15[/tex]
Hence, the rate of change is 15

A box of photographs contains 13 wedding photographs 4 vacation photographs and 8 holiday photographs one is randomly selected what is the probability that the photograph is a holiday photograph given that it is not a wedding photograph
Answers
so
desired outcomes is the 'not wedding' photos
there are 4 vacation and 8 holiday
so 12 'not wedding' photos
12=desired outcomes
total outcomes is 13+4+8=25
so the probablity would be 12/25 or about 48%
The probability that a randomly selected photograph from the box is a holiday photograph, given that it is not a wedding photograph, is 2/3 or approximately 0.67.
The question involves calculating the probability of drawing a holiday photograph from a box, given that the photograph is not a wedding photograph. First, we determine the total number of non-wedding photographs, then we find the probability that a photo selected is a holiday photograph from that subset.
There are 13 wedding photographs, 4 vacation photographs, and 8 holiday photographs. Given that we're not selecting a wedding photograph, we're only considering the vacation and holiday photographs, which total 4 + 8 = 12 photographs. The event of selecting a holiday photograph then has 8 favorable outcomes (since there are 8 holiday photographs).
The probability that the photograph is a holiday photograph given that it is not a wedding photograph is calculated by dividing the number of holiday photographs by the total number of vacation and holiday photographs:
Probability = Number of holiday photographs / Total number of non-wedding photographs = 8 / 12 = 2/3 or approximately 0.67

C 450
D 900
Answers
Answer:
the answer is d
Step-by-step explanation
correct on Edge
The answer is Option D)
The number of cars that are expected to pass through the toll booth each half-hour will be 900
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of cars that pass through the toll booth at each minute = 30
Let the number of cars to pass at each half-hour be A
1 hour = 60 minutes
half-hour = 30 minutes
So,
The number of cars to pass at each half-hour A =
The number of cars that pass through the toll booth at each minute x 30
The number of cars to pass at each half-hour A = 30 x 30
= 900 cars
Hence , The number of cars that are expected to pass through the toll booth each half-hour will be 900

Gene paid a deposit on a leased car. The deposit earns 2.8 percent simple annual interest. At the end of the year, the interest that is earned is $22.40. What was the amount of the original deposit?
Answers
I = PRT...we are going to rearrange this because we are looking for the principle...
I / (RT) = P
I = 22.40
R = 2.8%...turn to a decimal = 0.028
T = 1
sub and solve
22.40 / (0.028(1) = P
22.40 / 0.028 = P
800 = P....amount of original deposit is $ 800 <==
I=prt

The hypotenuse in a 30-60-90 triangle is the shorter leg doubled. So, it's 2x where x is the shorter leg.
In fact, the square root of two is not used to calculate any other sides in a 30-60-90 triangle. The shorter leg is x, the medium leg is x√3, and the hypotenuse is 2x.

tan(Y) = opp/adj = 8/15
cos (X) = adj / hyp = 8/17
tan(X) = opp/adj = 15/8
sin(Y) = opp / hyp = 8/17
