Answer:

scale factor = \frac{14}{5}

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original.

scale factor = \frac{7}{2.5} = \frac{7(2)}{2.5(2)} = \frac{14}{5}

An owner of Honda City car sells his car at a price of RM 7.50,000 with a loss present of 12.5%. Then find the price at which he
Mars2501 [29]

Answer:

Cost = RM 857143

Loss = RM 107143

Step-by-step explanation:

<u>Given:</u>

  • Selling price SP = RM 750000
  • Loss% = 12.5
  • Cost price CP = x

<u>Cost price is found as:</u>

  • SP = CP - 12.5%
  • 750000 = x - 12.5%
  • 750000= x*(100-12.5)/100
  • 750000= 0.875x
  • x= 750000/0.875
  • x≈ RM 857143

<u>Loss is:</u>

  • RM 857143 - 750000 = RM 107143

Given that (1, 0, 1) is a solution to a system of three linear equations, which of the following is true about the system?
Anna35 [415]
<h3>Answer:  Choice C) </h3><h3>The system can only be independent and consistent</h3>

===========================================================

Explanation:

Let's go through the answer choices

  • A) This isn't possible. Either a system is consistent or inconsistent. It cannot be both at the same time. The term "inconsistent" literally means "not consistent". It's like saying a cup is empty and full at the same time. We can rule out choice A.
  • B) This is similar to choice A and we cannot have a system be both independent and dependent. Either a system is independent or dependent, but not both. Independence means that the two equations are not tied together, while dependent equations are some multiple of each other. We can rule out choice B.
  • C) We'll get back to this later
  • D) The independence/dependence status is unknown without the actual equations present. However, we know 100% that this system is not inconsistent. This is because the system has at least one solution. Inconsistent systems do not have any solutions at all (eg: parallel lines that never cross). We can rule out choice D because of this.

Going back to choice C, again we don't have enough info to determine if the system is independent or dependent, but we at least know it's consistent. Consistent systems have one or more solutions. So part of choice C can be confirmed. It being the only thing left means that it has to be the final answer.

If it were me as the teacher, I'd cross out the "independent" part of choice C and simply say the system is consistent.

Which quadratic function has a wider graph than y=2x^2?
ioda

so all those quadratics have their parent y = x², which has the graph of a "bowl".

and depending on the coefficient, the bowl is wider or not.

the larger the coefficient, the narrower the bowl, the smaller the coefficient, the wider the bowl.

well, 1/2 is smaller then 2, thus y = (1/2)x² is wider than y = 2x².

The scale on a map says that 6 cm represents 15 km. What distance on the map in centimeters represents 20 kilometers?
ale4655 [162]

Answer:

8 centimeters.

Step-by-step explanation:

6cm\ on\ map\ -> 15km\\

Divide 3 both sides:

2cm\ on\ map\ -> 5km

Multiply 4 on both sides:

8cm\ on\ map\ -> 20km

8cm on the map represents 20km.
