Answers

Answer: A - one solution, B - Infinite solutions, C - no solutions

Step-by-step explanation:

Solutions of linear equations are any points at which both lines intersect. The point of intersection provides a point that lies on both lines and satisfies both equations - hence why it is called a "solution" to the system of equations.

In the first diagram, the lines intersect once. There is only one solution to this system of equations at (2, 4).

In the second diagram, the lines are identical. They intersect for any possible value, meaning it has infinite solutions.

In the third diagram, the lines are parallel. They will stretch to infinity without ever intersecting each other, so this system has no solution.

-4.7 yd
-7.1 yd
-9.4 yd
-28.3 yd

Answers

Answer:

B 7.1 yd

Step-by-step explanation:

The approximate area of the circular garden is 7.1 square yards. Therefore, option B is the correct answer.

What is area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the base of the rectangular grassy area is 6 yards by 3 yards.

A circular garden is surrounded by a rectangular grassy area.

Here, diameter of a circular garden is 3 yards and the radius is 1.5 yards.

We know that, area of a circle is πr²

The area of circular garden is 3.14×1.5²

= 3.14×2.25

= 7.065

≈ 7.1 square yards

Therefore, option B is the correct answer.

Jonathan replaced the original factory tires (P220/65 R 18) on his pickup truck with (P255/60 R 17) tires. Calculate the circumference of Jonathan’s ORIGINAL tires. Explain your results

Answers

Answer:

92 inches

Step-by-step explanation:

When a tire's size = P220/65 R 18, it means that:

the rim is 18 inches wide (or 457 millimeters)the width of the tire is 8.7 inches (or 220 millimeters)the sidewall of the tire is 5.65 inches (or 144 millimeters)the 65 shows the relationship between tire width and sidewall (65%)

the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches

the circumference = 2 x π x radius   or   diameter x π = 29.3 x 3.141592 = 92 inches

Answer:

The circumference of Jonathan’s original tire is 92 inches.

Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary. Charlene is going to reduce her net income by $125 each month and put this money towards paying down her debt. What will Charlene’s new net income be?

Answers

Answer:

A. $113.70

Step-by-step explanation:

The new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.

What is debt?

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

Charlene net income = 7% of her monthly salary

Charlene net income = 3410(7/100) = $238.7

After paying the $125 from the net income:

= 238.7 - 125

= $113.7

Thus, the new net income of Charlene is $113.7 if Charlene has a monthly salary of $3,410. With her present budget, Charlene has a net income that is 7% of her monthly salary.

Find the scale factor of a cube with volume 216 ft^3 to a cube with volume 1000 ft^3.

Answers

Answer:

Scale factor of  cube to the smaller cube is 5 : 3.

Step-by-step explanation:

Ratio of the volumes of two cubes = [tex]\frac{\text{volume of large prism}}{\text{Volume of small prism}}[/tex]

                                                          = [tex]\frac{1000}{216}[/tex]

                                                          = [tex]\frac{125}{27}[/tex]

Scale factor of these cubes = [tex]\sqrt[3]{\text{ratio of the volumes of the cubes}}[/tex]

                                              = [tex]\sqrt[3]{\frac{\text{volume of large prism}}{\text{Volume of small prism}}}[/tex]

                                              = [tex]\sqrt[3]{\frac{125}{27} }[/tex]

                                              = [tex]\frac{5}{3}[/tex]

                                              = 5 : 3

Therefore, scale factor of  cube to the smaller cube is 5 : 3.

What are the domain and range of the function? f(x)=3/5x^5
Domain: (−∞, 0)∪ (0, ∞) Range: (0, ∞)
Domain: (−∞, 0)∪ (0, ∞) Range: (−∞, 0)
Domain: (−∞, ∞) Range: ​(−∞, 0)​
Domain: ​(−∞, 0)∪ (0, ∞)​ Range: (−∞, 0)∪ (0, ∞)

Answers

Answer:

Domain: ​(−∞, 0) ∪ (0, ∞)​; Range: (−∞, 0) ∪ (0, ∞)

Step-by-step explanation:

See attachment.

We want to find the domain and range of the function [tex]f(x)=\frac{3}{5} x^5[/tex].

The domain is the set of all possible x-values that are included in the function, while the range is the set of all possible y-values that are included in the function.

Look at the graph.

We can see that the x-values can go into infinity except when approaching the line x = 0. Here, the function will never touch x = 0 because that would make the graph undefined. So, we can say that the domain is all real numbers except for x = 0, or ​(−∞, 0) ∪ (0, ∞).

It's the same thing with the y-values. Although it looks like the line is touching the y-axis, or the line y = 0, the graph actually is not - it's just going really close to it. So, the range is again ​(−∞, 0) ∪ (0, ∞).

Thus, the answer is D.

Answer:

Last one

Domain: ​(−∞, 0)∪ (0, ∞)​ Range: (−∞, 0)∪ (0, ∞)

Step-by-step explanation:

f(x) = 3/(5x⁵)

Since x is in the denominator, x can not be 0

Domain: all real values of x except 0

For y = 0, x has to be infinite therefore y can not be 0

Range: all real values except 0

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?

Answers

Question:

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?

A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

B) The ratio 92/200 represents the number of trials in this experiment.

C) The ratio 92/100 represents the theoretical probability of the coin landing heads up in this experiment.

D) The ratio 92/100 represents the number of occurrences of the coin landing heads up in this experiment.

Answer:

A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

Step-by-step explanation:

Given that the number of times, n, Tia flipped a coin is 200 times, heads and tails landed 92 and 108 times respectively.

ie, n = 200

E(Head) = 92

E(Tail) = 108

Let's calculate the following probabilities:

Probability the coin landed heads =

P(H) = [tex] \frac{num of heads}{total num} = \frac{92}{200} = 0.46 [/tex]

Probability the coin landed tails =

P(H) = [tex] \frac{num of tailss}{total num} = \frac{108}{200} = 0.54 [/tex]

Here, the experimental probability of an event can be derived using:

Number of favourable events / total number.

The expermental probability of the coin landing heads up would be:

Number of heads / total number

[tex] = \frac{92}{200} [/tex]

Therefore the correct option is option A.

The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

A is the answer

Then you can see that angle WCR is 154° because of vertical angles.

Arc RW is 154° too because WCR is a central angle.

Arc ZW is 26° because WCX is a central angle.

All we have to find now is angle ZCR.

You can see that ZCR and XCW are vertical angles.

ZCR = 26°

Arc ZR is also 26° because ZCR is a central angle.
