Is PRB congruent to QSB? Justify your answer.
This problem requires you to show your work and explain your reasoning.
Be sure to -
• Mark given information on the diagram
• Answer the question
• Provide justification statements that are mathematically correct
Answers
Answer:
When looking at this model, and asking yourself the question, is PRB congruent to QSB? PRB is in fact congruent to QSB. Congruent means that two figures have the same shape/size, no matter if it's mirrioring or not it is congruent. In this image, PRB is one shape, and QSB is another. They have the exact same points and they're also the same shape, but one is flipped the right side up. It was also stated PQ and RS bisect eachother at point B, <p is congruent to <Q, and <R is congruent to <S proving all these connections make this figure conguent.

20% of the total candy in a basket is Reese's chocolate. There are 8 Reese's in the basket. What is the total number of pieces of candy in the basket?
Answers
Answer:
I believe it is 40. I'm not 100% sure though
Step-by-step explanation:
If 20% of the candy is reese's and there are 8 reese's in the basket, to find the answer you must multiply 8 by 5. You multiply 8 by 5 because to get 100% you have to multiply 20% by 5 to get 100%.

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-5x - y = 12
y = -4x - 9
Step 2: Solve for x
Substitution
Substitute in y: -5x - (-4x - 9) = 12Distribute negative: -5x + 4x + 9 = 12Combine like terms: -x + 9 = 12Subtract 9 on both sides: -x = 3Divide -1 on both sides: x = -3Step 3: Solve for y
Define original equation: y = -4x - 9Substitute in x: y = -4(-3) - 9Multiply: y = 12 - 9Subtract: y = 3Write 0.25x+1y=12 in slope-intercept form.
Answers
Answer:
y = -.25x + 12
Step-by-step explanation:
Subtract x on both sides.
y = -.25x + 12
There is your answer. The "1" before the y doesn't need to be written, as a rule in algebra, ones do need to be written and are assumed to be there if there is no number at all.
-.25 is the slope and 12 is the y-intercept.
how many squares would have to be shaded to that 1/6 of the shape is shaded
Answers
Answer:
3 squares
Step-by-step explanation:
Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).
Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares
Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded

Answer:y= (3/4)x -7/4
Step-by-step explanation:
[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]

y + 1 = (3/4)x - 3/4

Jaylen has a pet grooming business. In 2018, he groomed 200 dogs. In 2019, he groomed 450 dogs. What was the percent increase in the number of dogs groomed? Don't forget your % sign.
Answers
Answer:
Percentage increase= 125%
Step-by-step explanation:
Giving the following information:
2018= 200 dogs
2019= 450 dogs
To calculate the percentage increase, we need to use the following formula:
Percentage increase= [(2019 - 2018)/2018]*100
Percentage increase= [(450 - 200)/200]*100
Percentage increase= 125%
11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *
Answers
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The equation to find the length of the fallen part of the tree is
[tex]x=\sqrt{8^2+13^2}[/tex]
Right Triangle.
Right triangles is a triangle with one angle is 90 degree.
The side opposite to 90 degree is the hypotenuse.
Pythagorean Theoremthe sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The length of the fallen part of the tree is the hypotenuse
Hypotenuse is 'x'
Base of the triangle is 13 feet and height is 8 ft
Apply Pythagorean theorem to find out the hypotenuse 'x'
[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]
the equation to find the length of the fallen part is
[tex]x=\sqrt{8^2+13^2}[/tex]
