Does the line passing through the points (-4, 3) and (6, -2) intersect the line passing through the points (-6, 6) and (-2, 4)?
Answers
Answer:
No.
Step-by-step explanation:
1) if the given line passing through the points (-4;3)&(6;-2) is line a, and the another given line is b, then
2) it needed to compare the slopes of a and b:
[tex]slope(a)=\frac{-2-3}{6+4}=\frac{-1}{2};[/tex]
[tex]slope(b)=\frac{4-6}{-2+6}=\frac{-1}{2};[/tex]
3) if slope(a)=slope(b), then the given lines a and b are parallel (no intersections).
During a weekend, the manager of a mall gave away gift cards to every 80th person who visited the mall.
• On Saturday, 983 people visited the mall.
• On Sunday, 1,033 people visited the mall.
How many people received a gift card?
Answers
Answer:
24
Step-by-step explanation:
983 / 80 to find the amount on saturday
983 / 80 = 12.2875
1033 / 80 to find the amount on sunday
1033 / 80 = 12.9125
add the whole numbers together as there was 12 lots of 80 people on both days
12+12 = 24
Answer:
on saturday 12 ppl, on sunday 12 ppl
Step-by-step explanation:
if 100 ppl are visiting then 80th person will receive gift. thats 100/80 and quotient is 1. so one person in first 100. 2 ppl in 200 ppl, 3 ppl in 300..and on.
980/80 will have quotient of 12. so 12 ppl on saturday
same way 1033/80 will have quotient of 12.

PQRST is a rectangular-based pyramid with a height of 9cm.
Find the angle between the line ST and the plane PQRS.
Give your answer correct to 1 decimal place.
Answers
Answer:
54.1° (1 dp)
Step-by-step explanation:
Let the center point of the rectangle PQRS = M
Calculate the length of the line SM using Pythagoras' Theorem:
a² + b² = c²
(11/2)² + (7/2)² = SM²
42.5 = SM²
SM = √42.5 cm
The height of the pyramid is 9 cm, therefore, MT = 9
Now we have a right angled triangle with base SM and height MT and hypotenuse ST
We want to find the angle TSM, so we can use the trig formula tan x = O/A, where x is the angle, O is MT and A is SM
tan TSM = MT/SM = 9/√42.5
TSM = arctan (9/√42.5) = 54.082088°
So the angle between the line ST and the plane PQRS = 54.1° (1 dp)

1. If QR = 12 and QR is a perpendicular bisector of TS, determine which of the following claims are true.
Answers
Answer:
see explanation
Step-by-step explanation:
Since QR is a perpendicular bisector then Δ RST is isosceles
with 2 congruent legs , that is
RT = RS , substitute values
6x - 4 = 3x + 8 ( subtract 3x from both sides )
3x - 4 = 8 ( add 4 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Then RS = 3x + 8 = 3(4) + 8 = 12 + 8 = 20
so RT = RS = 20
Using Pythagoras' identity in right triangle QRT
QT² + QR² = RS²
QT² + 12² = 20²
QT² + 144 = 400 ( subtract 144 from both sides )
QT² = 256 ( take square root of both sides )
QT = [tex]\sqrt{256}[/tex] = 16
In summary
RS = 12 is False ( RS = 20 )
x = 4 is True
x = 3 is False
QT = 16 is True

Similar triangles
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion. Also all the corresponding angles are congruent.
Using Pythagoras:
AC² = AB² + BC²
AC² = 2.5² + 6²
AC = 6.5
Using similar triangles:
BC / DE = AB / EF
6/DE = 2.5/5
DE = 12

Answers
Answer:
$121.5
Step-by-step explanation:
$180 × 0.25 = $45 <-- because it is a discount, we will subtract
$180 - $45 = $135 <-- price with 25% discount
$135 × 0.10 = $13.5

A scientist needs 10 L of a solution that is 60% acid. She has a 50% acid solution and a 90% acid solution she can mix together to make the 60% solution. Let x represent the number of liters of the 50% solution. Let y represent the number of liters of the 90% solution. Which equation represents the total liters of acid that are needed? Question 3 options: x y = 6 x y = 10 0. 5x 0. 9y = 6 0. 5x 0. 9y = 10.
Answers
Allegation is a method to find the ratio in which two or more indignant are mixed to produce a mixture or solution.
The equation represents the total liters of acid that are needed is,
[tex]0.5x+0.9y=6[/tex]
Thus the option 3 is the correct option.
What is allegation?Allegation is a method to find the ratio in which two or more indignant are mixed to produce a mixture or solution.
Given information-
A scientist needs 10 L of a solution that is 60% acid.
The percentage of two acid solution are 50% and 90%.
Variable x represent the number of liters of the 50% solution.
Variable y represent the number of liters of the 90% solution.
Quantity of acid from 50% solution is [tex]0.5x[/tex] liters, and quantity of acid from 90% solution is [tex]0.9x[/tex] liters.
As the scientist needs 10 L of a solution that is 60% acid. Therefore the quantity of acid in 60 percent acid solution is,
[tex]a=10\times\dfrac{60}{100} \\a=6[/tex]
Thus 6 liters of acid required by the scientist. As to get the 6 liters of acid from 50% and 90 percent solution, we need to add the amount of acid in these solutions.Thus,
[tex]0.5x+0.9y=6[/tex]
This is the required equation.
Hence the equation represents the total liters of acid that are needed is,
[tex]0.5x+0.9y=6[/tex]
Thus the option 3 is the correct option.

Solve the system of linear equations by substitution
2x+3y=0
8x +9y =18
Answers
Answer:
Step-by-step explanation:
Step 1:
Isolate x (1st Equation)
2x + 3y = 0
- 3y = -3y
2x = -3y
Step 2:
Divide both sides by 2
x = -3y/2
Step 3:
Replace the x from 8x with -3y/2 and Solve the equation
8(-3y/2) + 9y = 18
-12y + 9y = 18
-3y = 18
y = -6
Step 4:
Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0
2x - 18 = 0
+ 18 = +18
2x = 18
x = 9
Step 5:
Write your final answer.
(x, y) = (9, -6)
