how manh solutions does the system have​

Based on the price that Robin bought the watch and the price he sells it, his percentage loss is 30%.

This can be found by the formula:

= (Selling price - Purchase price) / Purchase price x 100%

Solving gives:

= (56 - 80) / 80 x 100%

= 24 / 80 x 100%

= 30%

In conclusion, Robin suffered a 30% loss.

Step-by-step explanation:

the answer is 5 all you got to do is take away 45 from 50

Answer:

m = 3 1/3

Step-by-step explanation:

I believe the question must be to find a value for m such that 3/m - 45/50.

 3/m = 45/50

45m = 150   [Cross multiply]

m = (150/45)

m = 3 1/3

The measure of m<FEJ is 75 degree

From the given figir, we can see that;

m< FHG =  m< EFJ = 15 degrees

Since the sum of angles in a triangle is 180 degrees, hence;

m< EFJ + 90 + m<FEJ = 180

15+  90 + m<FEJ = 180

m<FEJ = 180 - 105

m<FEJ = 75 deegrees

Probability helps us to know the chances of an event occurring. The correct option is A.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that an integer is needed to be chosen between 1 to 50 both inclusive. Therefore, the most likely integer to be chosen can be known by finding the probability.

A.)The integer selected will be even.

Probability of choosing Even number = 25/50 = 0.5

The integer selected will be a multiple of 5.

Probability of choosing a multiple of 5 = 10/50 = 0.2

The integer selected will be a multiple of 10.

Probability of choosing a multiple of 10 = 5/50 = 0.1

The integer selected will be a multiple of 20.

Probability of choosing a multiple of 20 = 2/50 = 0.04

Since the probability of choosing an even number is the greatest, therefore, the integer that is most likely to be selected will be even.

Answer:

20 lies between 16 and 25.

Step-by-step explanation:

Answer:

Step-by-step explanation:

x² - 7x - 18 = 0

Product = -18

Sum = -7

Factors = 2 , (-9)    {2*(-9) = -18  & 2 +(-9) = -7}

x²  + 2x - 9x - 18 = 0

x(x + 2) - 9(x + 2) = 0

(x +2)(x - 9)= 0

x + 2 = 0    ; x - 9 = 0

   x = -2     ; x  = 9

x = -2 , 9

Sale price = 272000

Reduction percentage = 15%

Let the original price = x

Reduction = 15% of x

Original price - reduction price = Sale price

x - 15% of x = £272000

[tex]x -\dfrac{15}{100}x = 272000\\\\\\\dfrac{100}{100}x-\dfrac{15}{100}x=272000\\\\\\\dfrac{85}{100}x=272000\\\\\\x=272000*\dfrac{100}{85}[/tex]

x = 3200 * 100

Answer: 20.25ft

1. Find what 8 inches in scale equal for the height of the house.

we will do this step by multiplying.

2in=4.5

8=?

to find...

2x4=8

so

4.5x4=18

2. Find what 1 inch on the scale is equal to for the height of the house.

we will do this by dividing 4.5 by 2

4.5/2=2.25

3. Add both the values for step 1 and 2.

we will do this by just adding them both

18+2.25=20.25

This is our answer, because first we found the value of 8 inches on the scale, which means that we are finding almost the full value of the 9 inches of the height of the house, then, we found 1 inch because 9-8=1, so if we already found 8, which is a number in the table of 2, we found out 1 so that we can add it with 8 to find the value of 9in on the scale. In this way, after adding, that gives us the value of 9in on the scale!

Answer:

(0,0)

Step-by-step explanation:

The y-intercept is where the parabola crosses the y-axis. The y-intercept is expressed as a coordinate pair, where x is always equal to 0 because the y-axis exists where x=0.

There are 2 ways to find the y-intercept of a function. The first way is to plug in 0 for x because you know that x=0 at the y-intercept. Then, solve for y.

[tex]y=0^2+3(0)[/tex]

y=0

The second, and easier, way to find the y-intercept is to use logic. Since you are plugging in 0 for x, all terms that have variables will equal 0. This means that all that is left are the constants. So, the easiest way to find the y-intercept is to just simplify the constants. Whatever this equals will be the y-value of the y-intercept. Since there are no constants written in this equation, the constant must be 0. If 0 is the constant, then that must mean that the y-value of the intercept is 0.

Answer:

x = 101 degrees

Step-by-step explanation

Answer:

x = 101°

Step-by-step explanation:

x and are same- side interior angles and sum to 180° , then

a + x = 180° , that is

79° + x = 180° ( subtract 79° from both sides )

x = 101°

The length of side MP in circle Q is 4.36.

A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.

From the circle:

∠OMP = 90° (angle in a semicircle)

Hence using Pythagoras theorem:

OP² = MP² + MO²

10² = 9² + MP²

MP = 4.36

The length of side MP in circle Q is 4.36.

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

Let larger number be X and smaller one be Y.

The two equations are :-

X = 2Y + 3

X = 2Y + 1

As you can tell, the slopes are the same and the y-intercepts are different. So, they will not intersect. Therefore, no solutions exist for this situation.
