In the figure, PQ is parallel to RS. The length of RP is 5 cm; the length of PT is 30 cm; the length of QT is 60 cm. what is the length of SQ?
A. 10 cm
B. 2 cm
C. 6 cm
D. 20 cm
thank you!
Answers
Answer:
10 cm
Step-by-step explanation:
because RT = 35 and RS = 75 so ST = 70
The length of SQ is 10 cm.
Option A is the correct answer.
We have,
Two similar triangles.
ΔTPQ and ΔTRS
So,
TR/TP = TS/TQ
TR = (TP +PR)
TS = (TQ + QS)
Substituting.
TR/TP = TS/TQ
(TP + PR)/TP = (TQ + QS)/TQ
(30 + 5) / 30 = (60 + QS) / 60
35/30 = (60 + QS) / 60
7/6 = (60 + QS) / 60
7 = (60 + QS) / 10
70 = 60 + QS
QS = 70 - 60
QS = 10
Thus,
The length of SQ is 10.

60 people attend a game night. Everyone chooses to play chess, a two-player game, or cribbage, a four-player game. All 60 people are playing either chess or cribbage.
There are 3 more games of cribbage being played than games of chess being played. How many of each game are being played
Answers
Answer: 8 chess matches and 11 cribbage matches.
Step-by-step explanation:
60 people, 4 people play a match of cribbage, so if theres 3 more matched than chess we can subtract that from the total 60 to get the answer. 3x4=12 60-12=48, 2 people per chess game and 4 people per cribbage game add them 6, 48 divided by 6 since its an even amount now, 48/6=8 add 8 matched to the remaining 3 for the cribbage.
8 chess games are being played while 11 cribbage games are being played.
Let x represent the number of chess games and y represent the number of cribbage games.
Since there are 60 people, chess is a two-player game and cribbage is a four-player game, hence:
2x + 4y = 60 (1)
There are 3 more games of cribbage than games of chess, hence:
y = x + 3
-x + y = 3 (2)
Solving equations 1 and 2 simultaneously gives:
x = 8, y = 11
Therefore 8 chess games are being played while 11 cribbage games are being played.

What is an equation of the line that passes through the point (6,6) and is parallel to the line 3x-2y=4?
Answers
Answer:
Fraction: y= 3/2x-3
or
Decimal: y= 1.5x-3
Step-by-step explanation:
Turn 3x-2y=4 into y=mx+b form
Subtract 3x from both sides
-2y=4-3x
Divide -2 from both sides
y= -2+3/2x
y= 3/2x-2
Since the line is parallel, use slope 3/2

What conclusion can you draw from the following statements using the Law of Syllogism?
• If a figure is a square, then it has four sides.
• If a figure has four sides, then it is not a triangle
The potions for the answer is in the photo
Answers
Using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.
The law of Syllogism is a method of deductive reasoning which involves drawing a conclusion from two premises.
Applying this law, there are usually three statements.
The first and second statements are the premises. The first statement is the major premise that connects to the second statement.The third statement is the conclusion derived from the two premises stated earlier.For example:Statement 1: If a, then b (premise)
Statement 2: If b then c (premise)
Statement 3: If a, the c (conclusion)
In the question above, in the same vein, from the first and second statement, we can conclude that:
If a figure is a square, then it is not a triangle, because a square has 4 sides and a triangle doesn't.
Therefore, using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

30 POINTS AND WILL MARK BRAINLY Graph the line that passes through the points (-3,-8) and (2,-3) and determine the equation of the line
Answers
Answer:
y = x - 5 :)
Step-by-step explanation:
use point-slope form to create an equation for this line.
find the slope first by subtracting the y-values from each other, and the x-values from each other.
-3-(-8) = 5 <- y-value
2-(-3) = 5 <- x-value
5/5 = 1 <- slope
plug the slope and one of the points into the point-slope equation.
y - (-3) = 1(x - 2)
y + 3 = x - 2
subtract 3 from both sides.
y = x - 5
graph this by placing a point on -5 on the y-axis, and going up by 1 and right by 1 for the slope of 1.
hope this helped! xoxxo
Step-by-step explanation:
Hey there!
The line passes through points; (-3,-8) and (2,-3).
Now; use formula for double point.
[tex](y - y1) = \frac{y2 - y2}{x2 - x1} (x - x1)[/tex]
Put all values.
[tex](y + 8) = \frac{ - 3 + 8}{2 + 3} (x + 3)[/tex]
Simplify it.
[tex](y + 8) = \frac{5}{5} (x + 3)[/tex]
[tex]y = x + 3 - 8[/tex]
[tex]y = x - 5[/tex]
Therefore, the equation is y= x-5.

Answer:
Answers
Answer:
170
Step-by-step explanation:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 + 5 + 7 = 17
since Cindy ate 30, less than Ann and Ben together so, the equation is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 = 70
total = 170

Answers
Answer:

Step-by-step explanation:
The slope of MN = -1.
The slope of M.N. = -1.
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
Given information:
The two lines MN and M'N' are parallel.
Transformation rule:
Line MN was translated down to 4 units and right to 6 units to create line M'N'.
And line MN passes through two points (-2, 0) and (-6, 8).
Therefore, the slope of line MN,
= (8- 0)/(-6-2)
= -1
Since lines MN and M'N' are parallel, they have the same slope.
Therefore, the slope of M'N' is also -1.

5 less than a number is equivalent to 1 more than three times the number. the number is
Answers
Answer:
x = -1
Step-by-step explanation:
5 less than a number is equivalent to 1 more than three times the number
number = x
x - 5 = 3x + 1
now im going to get the numbers and variable on different sides
x - 5 + 5 = x
3x + 1 - 3x = 1
x + 3x = 4x
1 - 5 = -4
4x = -4
lastly im going to divide each side by 4
4x / 4 = x
-4 / 4 = -1
x = -1

Sally spent $14.85 to buy 13 flowers. She bought lilies, which cost $1.25 each, and tulips, which cost $0.90 each. How many of each flower did Sally buy?
CAN SOMEONE HELP ME WITH THIS ONE PLEASE!!!!!!!
Answers
a = lilies
13 - a = tulips
We have: 1.25a + 0.90(13 - a) = 14.85
=> 1.25a + 11.7 -0.90a = 14.85
=> 0.35a = 14.85 - 11.7 = 3.15
=> a = 3.15 ÷ 0.35 = 9
=> She bought 9 lilies and 4 tulips
