Answers
Which similarity statement is true?
ASRQ - ATRS
ASRQ - ARTQ
ASRQ - ARTS
ASRQ-AQRT
Answers
Answer:
It would be B (The 2nd option)
Step-by-step explanation:
The two triangles that can be considered similar are RTQ and SRQ. These two have one right angle and share angle Q, make them similar by AAA.
Both the 2nd option and the 4th option mention these triangles, but the triangles are not named correctly in the 4th option.
The similarity statement that is true is
ΔSRQ - ΔRTQ
The correct option is B.
What is congruent?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
The two triangles that are similar are RTQ and SRQ. According to the AAA (Angle-Angle-Angle) similarity criterion, since they share two congruent angles, ∠RTS and ∠STQ, they must be similar. Therefore, we can write:
ΔRTQ ~ ΔSRQ
This similarity statement means that triangle RTQ is similar to triangle SRQ. So, we can use the corresponding parts of similar triangles to write:
SR / RT = SQ / TQ = RQ / RQ
where SR, RT, SQ, TQ, and RQ are the corresponding side lengths of the two triangles.
Since RQ / RQ = 1, we can simplify the above equation to:
SR / RT = SQ / TQ
This means that the ratios of the corresponding side lengths of the two triangles are equal. We can use this to find the true similarity statement:
ΔSRQ ~ ΔRTQ
So, the correct similarity statement is:
ΔSRQ - ΔRTQ.

look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1

another one : f(x)= 3(0)-1
3 multiplied by 0 gives you 0 therefore you are left with -1
by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

Evaluate if x = 4.
f(x) = = - 3x + 8
Answers
Given that,
f(x) = -3x + 8
To find,
The value of f(x) at x = 4.
Solution,
We have,
f(x) = -3x + 8
We need to find the value of f(x) at x = 4
Pu x = 4 in f(x).
f(4) = -3(4) + 8
= -12 +8
= -4
So, f(4) is equal to -4.
A salesperson works 40 hours per week at a job where he has two options for being paid. Option A is
an hourly wage of $22. Option B is a commission rate of 4% on weekly sales. How much does he
need to sell this week to earn the same amount with the two options?
thank you so much!
Answers
His salary for 40 hours per week with an hourly rate is hours x the rate:
40 hours x $22 per hour = $880 per week.
If he is paid commission, to make the same , he needs to make $880 iin commissions.
The commission rate is 4%, to find how much sales is needed divide the amount he needs to make ( $880) by the rate:
880/ 4% = 880/ 0.04 = $22,000
He needs to sell $22,000

Hi I rly need some help plz answer;)
Answers
Answer:
Step-by-step explanation:
1.8kg into grams
1.8kg = 1800 grams
Total toys = 6
Weight of one toy = 1800 ÷ 6 = 300 grams
Weight of 4 toys = 300 x 4 = 1200 grams = 1.2kg
Answer:
Step-by-step explanation:
a) 1 Kg = 1000 grams
1.8 Kg = 1.8 * 1000 = 1800.0 = 1800 grams
b) Weight of one toy = Weight of all the 6 toys ÷ 6
= 1800 ÷ 6
= 300 grams
c) Weight of 4 toys = 4 * 300
= 1200 grams
= 1200 ÷ 1000
= 1.2 Kg

A biology test is worth 100 points and has 36 questions.
a. Multiple-choice questions are worth 2 points each and essay questions are worth 6 points each. How many questions of each type are on the test?
b. Your friend says that it is possible for the multiple-choice questions to be worth 4 points each. Is your friend correct? Explain.
Answers
Answer:
(a) 7 essays and 29 multiple questions
(b) Your friend is incorrect
Step-by-step explanation:
Represent multiple choice with M and essay with E.
So:
[tex]M + E= 36[/tex] --- Number of questions
[tex]2M + 6E = 100[/tex] --- Points
Solving (a): Number of question of each type.
Make E the subject of formula in [tex]M + E= 36[/tex]
[tex]E = 36 - M[/tex]
Substitute 36 - M for E in [tex]2M + 6E = 100[/tex]
[tex]2M + 6(36 - M) = 100[/tex]
[tex]2M + 216 - 6M = 100[/tex]
Collect Like Terms
[tex]2M - 6M = 100 - 216[/tex]
[tex]-4M = - 116[/tex]
Divide both sides by -4
[tex]M = \frac{-116}{-4}[/tex]
[tex]M = 29[/tex]
Substitute 29 for M in [tex]E = 36 - M[/tex]
[tex]E = 36 - 29[/tex]
[tex]E = 7[/tex]
Solving (b): Can the multiple questions worth 4 points each?
It is not possible.
See explanation.
If multiple question worth 4 points each, then
[tex]2M + 6E = 100[/tex] would be:
[tex]4M + xE = 100[/tex]
Where x represents the number of points for essay questions.
Substitute 7 for E and 29 for M.
[tex]4 * 29 + x * 7 = 100[/tex]
[tex]116 + 7x = 100[/tex]
Subtract 116 from both sides
[tex]116-116 + 7x = 100 -116[/tex]
[tex]7x = 100-116[/tex]
[tex]7x = -16[/tex]
Make x the subject
[tex]x = -\frac{16}{7}[/tex]
Since the essay question can not have worth negative points.
Then, it is impossible to have the multiple questions worth 4 points
Your friend is incorrect.
The test contained 29 multiple choice questions and 7 essay questions.
Let x represent the number of multiple questions and y represent the number of essay questions.
Given that there are a total of 36 questions, hence:
x + y = 36 (1)
Also, the test is worth a total of 100 points, hence:
2x + 6y = 100 (2)
Solving equation 1 and 2 simultaneously gives:
x = 29, y = 7
Therefore the test contained 29 multiple choice questions and 7 essay questions.

Based on the rate of depreciation each year, the amount of depreciation of the machinery in the sixth year will be $300.
What is the annual depreciation amount?The depreciation in the second year is:
= 6,000 - 5,700
= $300
The depreciation in the third year is:
= 5,700 - 5,400

Four of you enter in the race. You are told that only one will complete the course. What is the probability if you complete the Course. What is probability that you will not complete the course.
Answers
Answer:
25% probability that you complete the course
75% probability that you do not complete the course
Step-by-step explanation:
If there are a total of 4 individuals entering the race and only one is able to complete the course then the probability that you will complete the course would be
1/4 = 0.25 or 25%
This is because you only represent 1 out of the 4 total participants. The opposite would be the case to calculate the probability that you will not complete the course since there are three other candidates with that could have completed it, therefore...
3/4 = 0.75 or 75%
