Which best explains whether or not triangles RST and ACB are congruent?
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down.
The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C.
The figures are not congruent. Point R does not correspond with point A.
Answers
Answer:
Correct option: first one
Step-by-step explanation:
If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)
Then, if we translate the resulting points 2 units to the left, we would have:
S = (-1, -5) -> matches point C
R = (-1, -1) -> matches point A
T = (2, -1) -> matches point B
So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.
Correct option: first one

There are 1265 students at Cypress Middle School. 42% of the students are enrolled in PE. Which equation could be used to represent the number of students enrolled in PE?
Answers
Answer:
0.42* 1265=x
Step-by-step explanation:
There are 1265 students in Cypress Middle School. So we already know one part of the equation. 42% of these students are in PE. So we know that 42% of these 1265 students are in PE. Of these means you probably have to multiply 42% and 1265. 42% = 0.42. So to write an equation we take the 0.42 and 1265 and put it together. Therefore, 0.42 times 1265=x.

the tailoring?
A $16.04
B $20.37
C $27.16
D $29.62
Answers
Answer: $29.62
Step-by-step explanation:
6.79 * 3 = 20.37
9.25 * 1 = 9.25
So, 20.37 + 9.25 = 29.62
Answer:
D
Step-by-step explanation:
(6.79*3)+(9.25*1)=29.62
we multiply the cost of shortening a pair of pants by the number of pants brought and the cost of a dress multiplied by the number of dresses to get our answer

The value of the expression is -100/3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
- (-4) (-6) - 3/5 (10 + 15) - 1/3
Simplifying the expression.
= 4 x -6 - 3/5 x 15 - 1/3
= -24 - 3 x 3 - 1/3
= -24 - 9 - 1/3
= (-72 - 27 - 1)/3
= -100/3
Thus,
The value of the expression is -100/3.

Answers
Answer:
d) 3 1/4
Step-by-step explanation:
The equation for the total distance traveled per day is 1/4 ÷ 3 = 1/12 of the total distance
What is an 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 ,
Let the total distance traveled per day be represented as A
Now , the equation will be
The distance traveled for the last 3 days = 1/4 of the total distance
So ,
Total distance traveled per day = distance traveled for the last 3 days / 3
Substituting the values in the equation , we get
Total distance traveled per day A = ( 1/4 ) / 3
On simplifying the equation , we get
Total distance traveled per day A = 1/12 of the total distance
Hence , the equation is 1/4 ÷ 3 = 1/12

There are 20 children in the cast of a class play, and 8 of the children are boys. Of the boys, 4 have a speaking part in the play, and of the girls, 8
do not have a speaking part in the play. If a child from the cast of the play is chosen at random, what is the probability that the child has a
speaking part?
A: 2/5
B: 1/2
C: 3/5
D: 3/4
Answers
Taking into account the definition of probability, the correct option is option A.: The probability that the child has a speaking part is [tex]\frac{2}{5}[/tex].
There are 20 children in the cast of a class play, and 8 of the children are boys. Then, realizing the difference between the number of children and the number of boys you get that 12 of the children are girls.
On the other side, of the boys, 4 have a speaking part in the play, and of the girls, 8 do not have a speaking part in the play. Then, calculating the difference between the number of girls there are and the number of them that they do not have a speaking part in the play is obtained: 12 girls - 8= 4 girls. So, of the girls, 4 do not have a speaking part in the play.
Therefore, 4 + 4 = 8 of the children have a speaking part.
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]
In this case:
number of favorable cases= 8 of the children have a speaking part.number of possible cases= 20 childrenReplacing in the definition of probability:
[tex]P(A)= \frac{8}{20}[/tex]
Simplifying the fraction:
[tex]P(A)= \frac{2}{5}[/tex]
Then, the correct option is option A.: The probability that the child has a speaking part is [tex]\frac{2}{5}[/tex].

Step-by-step explanation:
The correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.
What is the ratio?The ratio is the representation of the fraction where this fraction is represented by the : symbol.
Given in the question number of plants that he watered every day is represented on the x-axis in the coordinate grid.
The number of gallons that he waters every day is represented on the y-axis in the coordinate grid.
We have to check the ratio of the y coordinate and the x coordinate is different from other options.
By checking all the options
Option A: (16,4) ratio of gallons of water and plants that are watered is 4/16= 1/4= 1:4
Option B: (8,2) ratio of gallons of water and plants that are watered is 2/8= 1/4= 1:4
Option C: (24,8) ratio of gallons of water and plants that are watered is 8/24= 1/3= 1:3
Option D: (48,12) ratio of gallons of water and plants that are watered is 12/48= 1/4= 1:4
By analyzing all options, Option A, B, D has a ratio 1:4. and Option C has a ratio 1:3.
Therefore the correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.

2x-96=554
2x=650
x=325
Answer:
The bench cost $229 and the garden table costs 229 + 96 = $325
Step-by-step explanation:
let the cost of the bench = x
the cost of the garden table = x + 96
x + (x + 96) = 554
2x + 96 = 554

it's not A because it is a right angle triangle.
it's not B because the ratio for an isoceles triangle is x:x:x√2. since a and b are not the same value, it can be assumed that it is not the answer

The longest side is hypotenuse.
Using Pythagorean theorem:
c² = a² + b²
16² = 8² + (8√3)²
256 = 256 True, so it is a right triangle.
Short leg = 8, long leg = 8√3
For 30-60-90 right triangle:
short leg = hypotenuse/2 = 16/2 = 8 , true:
long leg = short leg*√3 = 8√3, true.
