Answer:
r, a, t, i, o
Step-by-step explanation:
Looking back at the question before this, Among these points, circle the points where x<y (the first coordinate, x, is smaller than the second coordinate, y.) the points were a, t, o, i, r. Those are the circled numbers.
Looking at this problem now, we will count those letters up from the y axis, in an increasing order. (also it spells out ratio)

The coordinates of the vertices of △PQR are P (0, 1), Q (0, 0),
and R (−2, 0). Draw the triangle and its image △P′Q′R′ after a 180°
clockwise rotation about the origin. What are the coordinates of the
vertices of △P′Q′R′?
Step-by-step explanation:
step 1. P(0, 1) -> P'(0, -1)
step 2. Q(0, 0) -> Q'(0, 0)
step 3. R(-2, 0) -> R'(2, 0)

Answer:
a. Pop
b. 30 CDs
c. 230 CDs
Step-by-step explanation:
Given that "O" represents 20 CDs
a. The CD that was the mode is the CD that has as much "O", which is Pop.
Mode = Pop
b. Number of Rock CDs = 3 × 20 = 60 CDs
Number of Classical CDs = 1½ × 20 = 30 CDs
Therefore, 30 more CDs of Rock were sold than Classical CDs were sold
c. Pop = 5*20 = 100 CDs
Jazz = 2*20 = 40 CDs
Classical = 1½*20 = 30 CDs
Rock = 3*20 = 60 CDs
Total sold altogether = 100 + 40 + 30 + 60
= 230 CDs
Sam’s best friend kisses her 20 times while sam’s BF kisses her 102 times
How many times was Sam kissed
Tell your reasoning ?
Answer:
122 times
Step-by-step explanation:
20+102=122
(what is this question lol)
Answer:
Well. Depending on Sam's age, she could've been kissed many times. Not just boy her bf or bestie, anyone could kiss her throughout her life time. Your question is very vague and can have many answers. But I'll take a guess and say she was kissed more than 122 times.

15. Metal A has a density of 2.4g/cm3 and Metal B has a density of 1.8
g/cm3. Their masses are combined in the ratio 2:3 to make metal C which
has a mass of 60 grams. Find the density of the metal C*
Answer:
The density of the metal C is 2 g/cm³
Step-by-step explanation:
The parameters of the two metals are;
The density of the Metal A = 2.4 g/cm³
The density of the Metal B = 1.8 g/cm³
The ratio in which their masses are combined to make the metal C= 2:3
The mass of the metal C, m = 60 grams
Let, 'x', represent the mass of the metal A in the 60 grams of the metal C and let 'y' represent the mass of the metal B in the 60 grams of the metal C
Let the ratio of the metals A and B in the metal C = x:y = 2:3
Therefore;
The mass of the metal A in the metal C, x = (2/(3 + 2)) × 60 g = 24 g
The volume of the metal A in the metal C, V₁ = (24 g)/(2.4 g/cm³) = 10 cm³
The mass of the metal B in the metal C, y = (3/(3 + 2)) × 60 g = 36 g
The volume of the metal B in the metal C, V₂ = (36 g)/(1.8 g/cm³) = 20 cm³
The volume of the metal C, V = V₁ + V₂ = 10 cm³ + 20 cm³ = 30 cm³
The density of the metal C = ρ = m/V
ρ = (60 g)/(30 cm³) = 2 g/cm³
The density of the metal C, ρ = 2 g/cm³

For each data set listed, determine the requested values.
1. 72, 32, 74, 66, 71, 45, 38, 49, 66, 69, 75, 34, 102
put the numbers in order
32,34,38,45,49,66,66,69,71,72,74,75,102
Q1 = (38 + 45)/2 = 41.5
Q2 (the median) = 66
Q3 = (72 + 74)/2 = 73
Interquartile range (IQR) = Q3 - Q1 = 73 - 41.5 = 31.5

Q.1 Write the algebraic expressions
(i) Three times p added to four times r
(ii) The difference of 2p and 3q when 2p is less than 3q
(iii) Two-thirds of x added to 2y [3]
help?!
Answer:
(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]
Step-by-step explanation:
So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

Finding angles!!
Answer:
Angle 1: 115
Angle 2: 65
Angle 3: 115
Angle 4: 65
Angle 5: 115
Angle 6: 65
Angle 7: 115
Step-by-step explanation:
Find the value of angle 2 by applying the vertical angles theorem (65)
Find the value of angle 1 by applying the supplementary angles theorem from the original angle (180 - 65 = 115)
Find the value of angle 3 by applying the vertical angles theorem from angle 1 (115)
Angles 4, 5, 6, and 7 are on a line parallel to the orginal line, cut by the same transversal, so they have the same values, according to the same side interior/exterior angles theorems.
Peter has built a gazebo, whose shape is a regular heptagon, with a side length of $1$ unit. He has also built a pathway around the gazebo, of constant width $1$ unit, as shown below. (Every point on the ground that is within $1$ unit of the gazebo and outside the gazebo is covered by the pathway.) Find the area of the pathway.
Answer:
Area of pathway = 10.375 unit²
Step-by-step explanation:
Given - Peter has built a gazebo, whose shape is a regular heptagon, with
a side length of 1 unit. He has also built a pathway around the
gazebo, of constant width 1 unit, as shown below.
To find - Find the area of the pathway.
Proof -
Central angle = [tex]\frac{360}{7}[/tex] = 51.43°
Now,
Central angle / 2 = [tex]\frac{360}{14}[/tex] = 25.71°
And
height = [tex]\frac{1}{2}.\frac{1}{tan25.41}[/tex] = 1.038
Now,
Inner area of gazebo = 7·[tex]\frac{1}{2}[/tex]·1·(1.038) = 3.634 unit²
Outer area of gazebo = ([tex]\frac{2.038}{1.038}[/tex])²·(3.364) = 14.009 unit²
∴ we get
Area of pathway = Outer area - Inner area
= 14.009 - 3.634
= 10.375 unit²
⇒Area of pathway = 10.375 unit²
A service station sells gasoline for $3.25 per gallon
and diesel fuel for $3.00 per gallon. On Monday, the
service station's revenue from selling a total of 131
gallons of gasoline and diesel fuel was $404.25. How
many gallons of diesel fuel did the service station sell
on Monday? Show your work
A) 35
B) 55
C) 76
D) 86
Answer:
86
Step-by-step explanation:
86 x 3 + 45 x 3.25 = ? If it equals 404.25 than the answer is 86
76 x 3 + 55 x 3.25 = ? If it equals 404.25 than the answer is 76
55 x 3 + 76 x 3.25 = ? If it equals 404.25 than the answer is 55
35 x 3 + 96 x 3.25 = ? If it equals 404.25 than the answer is 35
The number you multiply by 3 is the answer.
86 x 3 + 45 x 3.25 = 404.25

A. 241 feet
B. 358 feet
C. 258 feet
D. 341 feet
Answer: A. 241 feet
Step-by-step explanation:
The figure shows two rectangular triangles.
These triangles are similar since they have two identical angles:
the first angle is 90 degrees;
the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.
The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.
Let's make the proportion:
[tex]\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\[/tex]
It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:
341.25 - 100 = 241.25 (feet)
241.25 ≈ 241 (feet)
Having trouble understanding....please help me.
Answer:
3:2
Step-by-step explanation:
Triangles ABC and PMN are similar. This is evident from the marks identifying equal angles.
The ratio of the two longest sides is 20:30, or 2:3.
The ratio of the two shortest sides is 12:18, or 2:3.
Finally, the ratio of the two sides of intermediate length is 16:24, or 2:3.
The scale factor of the alrger triangle to the smaller triangle is 3:2.
