If the triangle are similar, write a similarity
I’ll give you a virtual hug if you answer this right
statement and tell whether you would use
AA similarity, SAS similarity, or SSS
similarity. If not similar, explain why.
Explanation
Explanation:
We would use AA similarity criterion here because we can see two of the angles in each triangle are equal.
Write 2 equivalent fractions for the following fractions, use 2/2 and 3/3. 2/3
Answer:
[tex]\frac{4}{4} ,\frac{5}{5}[/tex]
Step-by-step explanation:
In order to find the answer to this question you need to remember that if the denominator and the numerator are the same they equal one or one whole.
[tex]\frac{2}{2} =1[/tex]
[tex]\frac{3}{3}=1[/tex]
[tex]\frac{4}{4}=1[/tex]
[tex]\frac{5}{5} =1[/tex]
As long as the numerator and the denominator are the same they will be equivalent to 2/2 and 3/3.
Hope this helps.

Step-by-step explanation:
We are given the two points of (5, 11) and (-5, -1).
Use the slope formula.
[tex]m=\frac{rise}{run}=\frac{-1-11}{-5-5} =\frac{-12}{-10} =\boxed{\frac{6}{5}}[/tex]
The correct option should be Option D.
Hope this helps you.

Answer:
4 ft by 8 ft
Step-by-step explanation:
Answer:
D. 4ft by 10ft
Step-by-step explanation:
Since each square represents 4 feet and the door is 2 blocks plus a bit up it can't be 8 ft since 8ft would only be 2 blocks exactly, this also rules out B since 12 ft would need to be 3 blocks high. this leaves A and D. The third square is only half of a normal square which means its half of 4, 2. You add this to 8 to get 10.

What is the slope of line a?
========================================================
Explanation:
Start at the point (0,1). This is the y intercept, which is where the graph crosses the y axis.
Then move down 1 and over to the right 4 spaces. We arrive at (4,0) which is the x intercept.
The process of "down 1, over to the right 4" can be thought of like this
rise/run = -1/4
rise = -1
run = 4
A rise of -1 indicates we go down 1 unit
The run of 4 means we move to the right 4 units
So that's why slope = rise/run = -1/4
-------------------------------------------------------
Here's another approach using the slope formula:
m = (y2-y1)/(x2-x1)
m = (0-1)/(4-0)
m = -1/4
I used the two points (0,1) and (4,0) as (x1,y1) and (x2,y2) respectively. This formula basically says "subtract the y coordinates, subtract the x coordinates in the same order, then divide the differences y over x".
-------------------------------------------------------
Side note: The line moving downhill, as we read from left to right, indicates a negative slope.
The sales tax for an item was $9.80 and it cost $490 before tax. Find the sales tax rate. Write your answer as a percentage.
Answer:
2%
Step-by-step explanation:
To solve this problem, a proportion would be best! We can set up the first fraction with the two numbers given to us. We'll use t to represent tax, and w to represent the whole. The first fraction will look something like this:
[tex]\frac{9.80t}{490w}[/tex]
Next, we'll set up our second fraction using knowledge of percents. Every percent is a part of 100%, so we can use 100 as our percent to represent the whole. Since we are solving for the percent that is out of 100, we'll use x to represent it. The final proportion should look like this:
[tex]\frac{9.80t}{490w} = \frac{x}{100w}[/tex]
To solve, we just need to cross-multiply and divide! First, multiply 9.80 by 100 to get 980. Finally, divide 980 by 490 to get a final answer of 2%. The sales tax rate is 2%. The final calculations are as follows:
9.80 X 100 = 980
980 / 490 = 2 or 2%
The temperature on a spring day is 70 degrees. The temperature increases by 1 degree every hour. Which of the following representations does not show the relationship between the number of hours (h) elapsed and the temperature (T) it has reached?
Answer:
B. [tex]T=h[/tex]
*Sorry, I'm probably too late
Step-by-step explanation:
If the answer was [tex]T=h[/tex], the starting temperature would be [tex]0[/tex]. This is wrong because the starting temeperature is supposed to be [tex]70[/tex].
find the value of x in the angle
Answer:
The answer would be B
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

Find the measure of
Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°
Which of the following linear equations

D. y= 3 - 3/4x
E. y= -1
F. y= 1/2x - 2
Answer:
A and D
Step-by-step explanation:
the slope is the number in front of the x, as in the formula y = a*x + b
the linear equations that have a negative value for a have a negative slope

dozen of one score?
Answer:
1/2 dozen of one score is 30%.
Step-by-step explanation:
As we know that 1 dozen = 12 units.
1/2 dozen = 1/2 times 12=6 units
1 score = 20 units.
By using this conversion, we get
6/2 times 100=30%
So 1/2 dozen of one score is 30%

Consider the standard form of an exponential function:
y = a (b)^x
1. How does changing the base number (inside the parentheses) change your graph? (10 points)
2. How does changing the number outside the parentheses change your graph? (10 points)
3. Create three new exponential equations to represent Alison, Cindy, and Javier. (30 points)
Alison loves social media and likes for her posts to be shared as much as possible while Cindy and Javier prefer for their posts to stay amongst their friends primarily.
I have number one please help with 2 and 3.
Answer:
2. If we plug in X = 0 into our problem ( Y = A(B)^X ) I would get Y = A which drastically changes the initial value, the Y-intercept, and the point on the graph. The point changes to (0,a) which becomes the new Y-intercept.
3. Cindy and Javier would be ln(x) and x^(1/2) as they will grow somewhat fast at first and then die out.
While Alison would be 1/(1+e^-x) representing an s curve showing a lot of growth and later evening out.

The answer to part [2] and [3] are given above.
What is a mathematical function? What is an exponential function? Differentiate between equation and expression? exponential function : An exponential equation is given by -y = A(B)ˣ
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the standard form of an exponential function -
y = a (b)^x
[2] - Changing the number outside the parenthesis will determine the amplitude scaling of the graph of (A)ˣ. For -
a > 1 (Magnitude will increase)
a < 1 (Magnitude will decrease)
a = 0 (Magnitude will become zero)
[3] - For Alison, we can write the expression as -
y{A} = 5000(1000)ˣ
For Cindy and Javier, we can write -
y{C} = (2)ˣ
y{J} = (3)ˣ
where -
[x] represents the number of posts.
Therefore, the answer to part [2] and [3] are given above.

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17
