coincident
Answer:
The system of linear equations consist of parallel lines
Step-by-step explanation:
Here, we want to classify the system of linear equations
Firstly, let us write both in the standard forms
For the first;
y = 3x + 2
For the second;
y = 3x-1
The general form of a linear equation is;
y = mx + b
where m is the slope and b is the y-intercept
In both cases, m = 3 and that means the slope is the same
When two lines have same slope values, they are said to be parallel to each other

What is the value of x? Enter your value as a decimal rounded to the nearest tenth,
Step-by-step explanation:
Use the Pythagorean Theorem ( [tex]a^{2}+b^{2} =c^{2}[/tex] )
The longest side is c = the hypotenuse, and a and b = the other sides of the triangle.
a = 4 First: [tex]4^{2}+x^{2}=8.5^{2}[/tex]
b = x Second: [tex]16+x^{2}=72.25[/tex]
c = 8.5 Third: [tex]x^{2}=56.25[/tex]
Fourth: [tex]x=\sqrt{56.25}[/tex]
Fifth: x = 7.5
Kathi had a rope of 63.45 m. She cut the rope into two pieces. If the length of one piece was 23.59 m, what was the length of the other piece?
Answer:length of the other piece=39.86m
Step-by-step explanation:
Total length of rope =63.45 m
length of one piece = 23.59 m
Since the rope was cut into two pieces, we subtract the length of known first piece from the total length
length of the other piece = 63.45 m-23.59 m=39.86m
A quadrilateral is inscribed in a circle. Find the measure of each missing angle as labeled below. Show your work and/or explain how you got your answer.
1 point for each correct angle measure and 1 point for explaining or showing how you got your answer. Don’t forget to label your answers.
Answer:
C = 95°
D = 72°
F = 108°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)
Using these relations, we have .
C = 180° -E = 180° -85° = 95°
D = 144°/2 = 72°
F = 180° -D = 180° -72° = 108°
What is the area, measured in square meters, of the parallelogram shown?
Round to the nearest tenth, if necessary.
Answer:
A = (11 m)(4.33 m) = 47.6 m^2
Step-by-step explanation:
The width of this parallelogram is (5 m)(sin 60 degrees), or approximately 4.33. This is the length of the dashed line shown.
The area of this parallelogram is A = (length)(width), which here is:
A = (11 m)(4.33 m) = 47.6 m^2

Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal
Ana took out a 4-year loan for 7,500 and paid 3.6% simple interest.How much was the total interest on the loan in dollars?
Answer:
I = $ 1,080.00
Step-by-step explanation:
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.6%/100 = 0.036 per year,
then, solving our equation
I = 7500 × 0.036 × 4 = 1080
I = $ 1,080.00
The simple interest accumulated
on a principal of $ 7,500.00
at a rate of 3.6% per year
for 4 years is $ 1,080.00.

A small measuring spoon holds 5 milliliters. How many spoons would 1 liter of liquid fill?
===================================================
Work Shown:
1 liter = 1000 milliliters
1 spoon = 5 milliliters
200*(1 spoon) = 200*(5 milliliters)
200 spoons = 1000 milliliters
200 spoons = 1 liter
Notice how 1000/5 = 200, so that's why I multiplied both sides of the second equation by 200 to end up with what is shown above.

51 / 51 + 17 = x / x + 12
51 / 68 = x / x + 12
51 ( x + 12) = 68x (After cross multiplication)
51x + 612 = 68x
612 = 68x - 51x
612 = 17x
x = 612/17 = 36

Compare and contrast pyramids and cones.
Be sure to use mathematical terms to describe parts of the solids.
a. In what ways are they alike?
b. In what ways are they different?
Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids.
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
Step-by-step explanation:
brainliest?
The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.
Pyramids and cones are alike in the following ways:
Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.
The formula for the area of a right angle triangle is:
A = hb/2
The area of a cone is given as:
A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]

Harrison is having a tub of yoghurt for a snack. The tub weighs 30g and holds 120ml, so he says that his snack (the tub and yoghurt together ) weighs 150g. Can you please explain why his mistake is mistaken please?
Step-by-step explanation:
Given
Tub weighs 30 g and can hold 120 ml yogurt
It is not right to simply write the ml to gm unless it is case of water
mass is given by product of volume with density
So, density of yogurt is different than water. It is not appropriate to write 120 ml to 120 gm
Thus, the claim of Harrison is wrong that his snack weighs 150 gm.

Answer:
90 pages
Step-by-step explanation:
Given: 70% of a book, 27 more pages
To find: How many pages there are in the book
Solution: If 70% is 27,
27 to the 20 it stands for is 20
70 + 20 = 90
Thus, there are 90 pages left in the book
