In the problem we’re supposed to find the value of x that makes ABC ~ RST I can’t figure it out can someone please help
Answers
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that [tex]\frac{a}{b} =\frac{c}{d}[/tex] is the same as a*d = b*c
[tex]\frac{44}{x+2} =\frac{20}{7}[/tex] is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4

In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. Steward scored 5 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Steward scored in each of the second, third, and fourth rounds if he earned a place in the finals? (1 point)
a
5 + 3p ≥ 30
b
5 + 3p ≤ 30
c
5p + 3 ≥ 30
d
5p + 3 ≤ 30

Given:
Score in first round = 5 points
Score in second, third and fourth rounds was identical.
A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round.
To find:
The inequality for the given problem.
Solution:
Let p be the number of points, p, that Steward scored in each of the second, third, and fourth rounds.
Score in first 4 rounds = Score of 1st round + Score of 2nd round + Score of 1s 3rd round + Score of 4th round
Score in first 4 rounds [tex]=5 + p + p + p[/tex]
[tex]=5 +3p[/tex]
A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. It means the total score in first 4 rounds must be greater than or equal to 30.
[tex]5+3p\geq 30[/tex]
Therefore, the correct option is A.

Olivia needs 545454 licks for every 333 lollipops she eats.
Answers
Answer:
54 lick per 3 lollipops is a unit rate of 18 licks per lollipop.
36 is 2 times 18, so it needs 2 times as many licks as 18 lollipops.
36 2
I assume the last line is 5 lollipops.
If 1 lollipop takes 18 licks, then 5 lollipops take 5 * 18 licks.
5 * 18 = 90
90 5
Answer: i think 2 because 90 divided by 5 is 18 and 54 divided by 3 is 18 so

what theorem can be used to prove the 2 triangles similar?
Answers
Answer:
C. SSS
Step-by-step explanation:
[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]
Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.
Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.

So the horse ran 2.25 miles in 150 seconds
To find the mile time in seconds divide 150 by 2.25 which equals 66.7sec per mile but it’s asking miles per minute and one mile is over a min so he runs Less than one mile per minute. So now you must divide 60 by 66.7 to find that he runs .89 miles per min.

If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse.
What is the inverse of a function?The inverse of a function is basically a reverse function or undo of the function.
For example y = f(x) then inverse will be x = f(y).
It means in the inverse function we need to interchange x and y.
Another example y = 3x² ⇒ x = √(y/3) will be the inverse.
An inverse function is a reflection of graph across y = x and due to that coordinate will interchange its that ;
( x ,y ) → ( y , x )
Since graph A is rotated about the x-axis to make graph B
Now,
Graph A is rotated( which is B ) and reflected across the axis y = x to form Graph C.
So B and C will be the inverse of each other.
Hence "If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse".

Answer:
Option BStep-by-step explanation:
Definition of variables: Variables are terms that have no coefficients.
To look for variables in the expression 2w + 11t + 4y, simply look for the variables (letters) in the expression. We can see that the variables are w, t, and y, which matches Option B.

Answers
Answer:
x=2
Step-by-step explanation:
We see that there is already a common variable that can be canceled out -- y. y+(-y)=0! (Alternatively you may also multiply an equation by negative 1 and do subtraction, but in this case it's already done for you)
So now we just do some addition.
2x+6x=8x
y+(-y)=0
7+9=16
This means that 8x=16. Now we solve!
(Divide both sides by 8)
We're left with x=2 :)

Answers
Answer:
No change ; = ; research ; parameter
Step-by-step explanation:
The Null hypothesis in a statistical test is always the initial truth which always means that a research scenario or statement is as it is or that there is no change whatsoever. The null hypothesis is usually denoted as H0 ; because it is always the initial truth or accepted claim, it usually takes a equal to sign, this denotes that, there is no change in parameter, either the population mean or any other statistical measure we wish to test. The alternative hypothesis on the other hand always negated the null hypothesis, because it brings up a claim which is to check or peruse the Null hypothesis, hence, it is a research hypothesis, denoted as Ha: ;
The alternative hypothesis contains the statement about the population parameter we wish to test( parameter is a measured value about the population).

Central angle = measure of intercepted arc
Central angle = 47°
Arc measure = 7 + 5x
Therefore:

Subtract 7 form both sides
5x = 47 - 7
5x = 40
Divide both sides by 5
x = 40/5
