No point given, but input it yourself

here is the equation

the equation of a line that has a slope of m and passes through the point $(x_1,y_1)$ is
$y-y_1=m(x-x_1)$

so given that the slope is -3 (and assuming your point is $(x_1,y_1)$ )
$y-y_1=-3(x-x_1)$ is the eqation

if we were to solve for slope intercept form, it would be
$y=-3x+3(x_1)+y_1$

A college has a student to teacher ratio of 35 to 2. If there are 180 teachers at the college, how many students attend the coll

Ray Of Light [21]

number of student attend the college are 3150

Step-by-step explanation:

the student teacher ratio is 35:2

let, there are 2x teachers

according to the problem,

2x = 180

or, x = 180/2

= 90

so number of students = 35 X 90 = 3150

Find the LCM of the following. A. 28,42,35 B. 48,72,96 C. 36, 44

Ne4ueva [31]

28/2= 14 42/2= 21 35/7= 5

14/ 2= 7 21/3= 7

28= 2^2 × 7

42= 2 × 3 × 7

35= 7 × 5

LCM= 420

48/2= 24. 72/2= 36. 96/3= 32

24/2= 12. 36/3= 12. 32/2= 16

12/3= 4. 12/3= 4. 16/2= 8

4/2= 2. 4/2= 2. 8/2= 4

4/2= 2

48= 2^4 × 3

72= 2^3 × 3^2

96= 2^5 × 3

LCM= 288

36/3= 12. 44/2= 22

12/3= 4. 22/2= 11

4/2= 2

36= 3^2 × 2^2

44= 2^2 × 11

LCM= 396

28 in 21 in., 20 in. Is this a right triangle?

ankoles [38]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
