Answer:

-4/3

Step-by-step explanation:

let (13,-4) be (x1,y1) respectively

(1,12) be (x2,y2) respectively

From,

slope=(y2 -y1)/(x2-x1)

=(12+4) /(1-3)

=16/-12

=-4/3

Answer:

Probability is 0.552, or about 55%

Step-by-step explanation:

first there are 20 marbles in total: odds are 15/20 = 3/4

Then, there are 19 marbles in total : odds are 14/19

So the odds of both of them being blue are: 3/4 * 14/19 = 0.552 (rounded to the thousandths place)

Answer:

si

Step-by-step explanation:

cuando sumamos la medida de un ángulo en el par con el otro ángulo en el par, el total será 180 grados.

No, the student is not correct. Because sum of a pair of adjacent angles not always sum up to 180°.

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

The sum of the measures of a pair of adjacent angles can be any number, including 180 degrees, but it does not have to be 180 degrees.

No, the student is not correct. Because sum of a pair of adjacent angles not always sum up to 180°.

Answer:

y = 3x + 6

Step-by-step explanation:

y2 - y1 / x2 - x1

9 - (-6) / 1 - (-4)

15/5

= 3

y = 3x + b

9 = 3(1) + b

9 = 3 + b

6 = b

Answer:

equation y = 3x + b.

Step-by-step explanation:  

To come up with the equation of a line in slope intercept form, we need the slope and the y-intercept. First, substitute the given slope in for m. We get the equation y = 3x + b.

Answer:

The median is $42, or B.

Step-by-step explanation:

Our numbers are :

42, 51, 38, 49, and 40.

The first step to finding the median is ordering the numbers from least to greatest.

38, 40, 42, 49, 51.

Now we find the number perfectly in the middle - that's 42, between 49 and 40. The median is $42, or B.

Answer:

volume left in A is 80ml

Step-by-step explanation:

let original volume in both be x ml

after pouring from A to B

vol in A = x - 120

vol in B = x + 120

now it is given that

vol in B = 4 times vol in A

implies

[tex]x + 120 = 4 \times (x - 120) \\ x + 120 = 4x - 480 \\ 3x = 600 \\ x = 200[/tex]

hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml

Answer:

A

Step-by-step explanation:

Given that f(x) is 2x-6, and g(x) is 3x+9, all we have to do is subtract in order to find (f(x)-g(x)):

[tex](f(x)-g(x))=\\\2x-6-(3x+9)=\\2x-6-3x-9=\\-x-15[/tex]

Answer:

14.286% increase

Step-by-step explanation:

Since the admission to the amusement park increased by $10 we need to find what percentage of $70 equals $10.

We can find this percentage by multiplying 10 (the difference in money) by 100 (a hundred percent), and dividing that by 70 (the initial cost)

[tex]10*100/70=14.286[/tex]

Answer:

Step-by-step explanation:

a) Given,

Total marks in English = 90

Marks scored by James = 60

Therefore,

Percentage of marks scored

[tex] = \frac{60}{90} \times 100[/tex]

= 66.67% (approx. )

Then,

Total marks in Science = 150

Marks scored by James = 78

Therefore,

Percentage of marks scored

[tex] = \frac{78}{150} \times 100[/tex]

= 52%

At last,

Total marks in Maths = 120

Marks scored by James = 75

Therefore,

Percentage of marks scored

[tex] = \frac{75}{120} \times 100[/tex]

= 62.50%

b) In English test James scored highest percentage.

Answer:

The cost of the car is $ RS 308,000.

Step-by-step explanation:

Given that the value of a car is deprecting at the rate of 12%, to find the correct value of car when cost of car was $ RS350,000 last year, the following mathematical calculation must be performed:

100 - 12 = 88

88/100 = 0.88

350,000 x 0.88 = X

308,000 = X

Therefore, the cost of the car is $ RS 308,000.

Answer:

x²+4² =8²

x²+16 =64

x² =64-16.

x² =48

x. =√48

answer is option D

Answer:

D

Step-by-step explanation:

The segment x is a perpendicular bisector and divides the triangle into 2 right triangles.

Using Pythagoras' identity in either of the 2 right triangles, then

x² + 4² = 8²

x² + 16 = 64 ( subtract 16 from both sides )

x² = 48 ( take the square root of both sides )

x = [tex]\sqrt{48}[/tex] → D

Answer:

18 monthly payments are required to complete payment

Step-by-step explanation:

We start with our $1,424.

Then subtract $560 from the original number above.

Leaving us with $864.

We then divide the $864 by $48 and we end up with 18.

So our answer is 18 monthly payments are required to complete payment.

Answer:

The answer is 6

Step-by-step explanation:

(0,6)

x=0,y=6

Substituting 0 for x and 6 for y

6=2(0) + b

6=b

or

6 = 3(0)+b

6=b

Therefore, b=6

Answer:

w = 16, x = 11, y = 6, z = 7.5

Step-by-step explanation:

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

scale factor = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]

Then by proportion

[tex]\frac{12}{w}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )

3w = 48 ( divide both sides by 3 )

w = 16

----------------

[tex]\frac{x}{12}[/tex] = [tex]\frac{3}{4}[/tex]

4x = 36

x = 9

-------------------

[tex]\frac{4.5}{y}[/tex] = [tex]\frac{3}{4}[/tex]

3y = 18

y = 6

[tex]\frac{z}{10}[/tex] = [tex]\frac{3}{4}[/tex]

4z = 30

z = 7.5
