The Equation of line u is y =-8/9x+5/4. The equation of line v is y =9/8x+7/4. Are line u and line v parallel or perpendicular?
Answer:
when two lines are parallel the two slopes are equal (m1 =m2)
when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)
m1 =1st slope
m2= 2nd slope
using the formula y= mx +c
m1= -8/9
m2= 9/8
since m1 is not equal to m2 and -8/9 × 9/8 = -1
It is perpendicular

A garden is in the shape of a trapezium whose parallel sides are 40m and 22m and the perpendicular distance between them is 12m. Find the area of the garden
Answer:
A = 372 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 12, b₁ = 40 and b₂ = 22 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²
x = 12

suppose river has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range?
She can have at least 3 and at most 6 dog treats in a day
River can have - n = 10/y number of treats to remain in her calorie range, where the calorie range is [y] calories.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
River has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range.
Assume the calorie range to be [y] calories and assume she can have [n] number of treats. We can write the linear function as -
10n = y
OR
y = 10n
This this the equation of the straight line. She can have -
n = 10/y
number of treats to remain in her calorie range.
Therefore, River can have - n = 10/y number of treats to remain in her calorie range.

Using a set of numbers find the mean round to the nearest tenth median mode and range 8,6,3,7,1,6,5,6
Answer:
Mean 5.3, Median 6, Mode 6, Range 7
Step-by-step explanation:
First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)
1, 3, 5, 6, 6, 6, 7, 8
Mean: is the average of all the numbers :add all numbers / how many numbers we have
(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)
Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8
(6+6)/2 = 6
Mode: is the number that appears the most so is 6
1, 3, 5, 6, 6, 6, 7, 8
Range: is the difference between the highest and the lowest value
1, 3, 5, 6, 6, 6, 7, 8
8-1 = 7
Answer:
Mean- 42
Median- 6
Mode- 6
Range- 7

In a particular year, a total of 49,652 students studied in two of the most popular host countries when traveling abroad. If 6786 more students studied in the most popular host country than in the second most popular host country,find how many students studied abroad in each country
How many students studied abroad in the most popular host country
x = most popular
y = second most popular
x+y=49652
x=y+6786
Substitute into the first equation
(y+6786)+y=49652
2y=49652-6786
2y=42866
y=21433
x=21433+6786=28219(answer)

Find the value of x for which a || b
Answer:
Since a and b are parallel
Step-by-step explanation:
2x+27=3x - 27
collect the like terms
3x-2x=27+27
x=54
PLS MARK BRAINLIEST
Answer:
x = 54
Step-by-step explanation:
If the lines are treated as parallel , then
(3x - 27) and (2x + 27) are alternate exterior angles and congruent, so
3x - 27 = 2x + 27 ( subtract 2x from both sides )
x - 27 = 27 ( add 27 to both sides )
x = 54
For a and b to be parallel then x = 54

a company had to extend a project from 276 days to 483 days. what was the precentage increase in time to complete the project?
Answer: 75% increase
Step-by-step explanation:
First, you subtract the two numbers to find out how much increased.
483-276= 207
Divide by original number
207/276= [tex]\frac{3}4}[/tex]
Multiply by 100
[tex]\frac{3}{4}*100=[/tex] 75% increase
