The equation of line L, is y= 5x + 1
The equation of line L, is 2y - 10x + 3 = 0
Show that these two lines are parallel.
Answer:
Step-by-step explanation:
2y=10x-3( i arranged it to make it easier)
y=(10x-3) divided by 2
y=5x-1.5
they are parallel because they have the same gradient/slope number.
pedro placed an order with an online nursery for 6 apple trees and 5 azaleas and the order came to $219. the next order for 3 apple tree and 4 azaleas came to $132. what was the unit cost for each apple tree and for each azalea?
The cost for each apple tree is; $24 and fit each azalea would be; $15.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let consider X = apples trees and Y= azaleas
Therefore, the system of equation is;
6x + 5y = 219
3x + 4y = 132
Solving;
-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15
Now substitute;
6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24
Thus, The cost for each apple tree is; $24 and fit each azalea would be; $15.

The two circles have different diameters in the ratio 5:3.
(A) Calculate the radius of circle B if circle A has a radius of 35mm
(B) Calculate the area of circle A giving your answer to the nearest cm squared.
Answer:
a) 21 mm
b) 39 cm^2
Step-by-step explanation:
a) The ratio of the diameter from A to B is 5:3
Let the diameter of B be x
If 35 is the radius of A, then its diameter is 35 * 2 = 70 mm
Thus;
5/3 = 70/x
5* x = 70 * 3
5x = 210
x = 210/5
x = 42 mm
So the radius of circle B will be 42/2 = 21 mm
b) The area of circle A
Mathematically we apply the area of a circle formula here
A = pi * r^2
A = 22/7 * 35 * 35
A = 3,850 mm^2
To convert this to cm^2, we will
need to divide by 100
That would be 3850/100 = 38.5 cm^2 = 39 cm^2
Sadie's office had already recycled 13 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 8 kilograms of paper each week. How many weeks will it take Sadie's office to recycle a total of 29 kilograms of paper?
Answer: 2 weeks
Step-by-step explanation:
The office had already recycled 13 kilograms of paper this year and need to recycle a total of 29.
The number of kilograms left is:
= 29 - 13
= 16 kilograms of paper
Recycling at a rate of 8kg per week, the number of weeks it will take them to reach 16 kilograms is:
= 16 / 8
= 2 weeks

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.
Answer:
Q= 126°
Step-by-step explanation:
Using the picture given, because these are parallel lines broken by a transversal, we can say the following
M=A=Q=F
B=C=D=G
Since, for example, M and C are the same line, we can say that M+C=180 and so on.
M=Q
Q= 126°
kiersten is 6ft tall. She is standing in front of a tree and notices her shadow. If her shadow is 9 feet away from her and the shadow of the tree is 84 feet away from the tree, how tall is the tree?
If kiersten is 6ft tall. She is standing in front of a tree and notices her shadow and her shadow is 9 feet away from her. The height of the tree is 56 feet.
How to find the height?Given data:
kiersten height = 6ft tall
Shadow = 9 feet away
Shadow of tree = 84 feet
The equation that will be use to find the height is 6/9= x/84
Let x represent the tree's height
So, let solve for x
6/9= x/84
Cross multiply:
9x = 6(84)
9x = 504
Divide both side by 9x
x= 504/9
x = 56 feet
Therefore we can conclude that the height of the tree is 56 feet.
