Given m||n, find the value of x and y
Answer:
x = 8
y = 29
Step-by-step explanation:
8x - 11 = 9x - 19
x - 19 = -11
x = 8
2y - 5 = 9x - 19
2y - 5 = 9(8) - 19
2y - 5 = 72 -19
2y - 5 = 53
2y = 58
y = 29

K is between P and Q. Suppose PQ- 10x - 16, PK - 6x + 8, and KQ-8. What is PQ?
Answer:
PQ = 64
Step-by-step explanation:
PQ = PK + KQ
10x - 16 = 6x + 8 + 8
10x - 16 = 6x + 16
4x = 32
x = 8
PQ = 10(8) - 16
= 80 - 16

ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)

Haley made 88% on a history test. The
test had 50 questions of equal point value.
How many questions did Haley miss?
Answer:
She missed 6 questions.
Step-by-step explanation:
88% can be written as (88/100) or as 0.88.
You can set this as a ratio problem which is,
88/100 = correct/50
correct = (88/100)*50 (multiply both sides by 50)
correct = 44
So, 50 (total questions) - 44 = 6 incorrect questions

A bowling ball is placed on the moon.
Which feature of the bowling ball stays the same?
A. force from gravity
B. weight
C. mass
Answer:
C. mass
Step-by-step explanation:
gravity is different on the moon
and weight is different because of that change in gravity
If the bowling ball is placed on the moon, the feature which will stays same, mass of the ball. So option C is correct
What is Force ?The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.
Given that,
A bowling ball is placed on the moon
So, when ball is placed on moon, it affects the following factors,
Force from gravity - On the Earth and on the Moon the gravitational force will be different.
Weight - On the Earth and On the Moon the gravitational acceleration will be different so weight will be different on both the planets.
Mass- It is the property of the object and it is independent from the planets, it will be same on every planet.
Hence, the Mass is same on both the planets

The space probe Voyager I travels 3.255 x 108 miles in a year.
At this rate, how far does the Voyager I travel during a period of 40 years?
The Voyager I travel 130.2 x [tex]10^8[/tex] miles during a period of 40 years.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
The space probe Voyager I travels 3.255 x [tex]10^8[/tex] miles in a year.
So, in 40 years Voyager I travel
= 3.255 x [tex]10^8[/tex] x 40
= 130.2 x [tex]10^8[/tex] miles.
Thus, the Voyager I travel 130.2 x [tex]10^8[/tex] miles.

An air conditioning system salesperson earns a base yearly salary of $38,000 and earns a commission of $500 for every air conditioning system sold. Using your equation from Question 1, how much will the salesperson earn if 22 air conditioning systems are sold in one year? Put the following steps in order.
Answer:
order
500x+38000
500(22)+38000
11000+38000
49000
Step-by-step explanation:
We can write the following equation
38000+500x= salary
where x is the number of air conditioners sold
To get the answer just plug in 22 for x
38000+500(22)=49000
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The steps in order are:
y = 500x + 38,000
y = 500 x 22 + 38,000
y = 11,000 + 38,000
y = 49,000 earned.

For example (-2)*(-2) is 4

Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200
