The point-slope form:

y-y_1=m(x-x_1)

We have a slope m = 4 and the point (-3, -1). Substitute:

y-(-1)=4(x-(-3))\\\\\boxed{y+1=4(x+3)}\to\boxed{b}

A bag of tokens contains 9 red, 6 green, and 5​ blue tokens. What is the probability that a randomly selected token is red and g
german

Answer:

27/200

Step-by-step explanation:

Knowing that:

A bag of tokens contains 9 red, 6 green, and 5​ blue tokens. What is the probability that a randomly selected token is red and green?

Solve:

and = multiply

Total = 9 red + 6 green + 5 blue = 9 + 6 + 5 = 20

Total = 20 token

Thus,

There are 9 red and 6 green..

Hence,

9 out of 20 is red

6 out of 20 is green

Equation

9/20 × 6/20

Multiply Across:

9 × 6 = 54

20 × 20 = 400

54/400

Simplify

27/200

Therefore, the probability that a randomly selected token is red and green is 27/200.

What is the length of SA?<br> 1.89 ft<br> 2.43 ft<br> O<br> 3 ft<br> 7 ft
Brums [2.3K]

Incomplete Question, Figure is not there the required figure is attached below.

Answer:

The Correct option is third one 3 ft.

Therefore length of SA is 3 ft.

Step-by-step explanation:

Given:

BS = 10 ft

BT = 9ft

TC = 2.7 ft

TS || CA

To Find:

SA = ?

Solution:

Basic Proportionality Theorem:

Basic Proportionality Theorem States that "If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio".

Here, TS || CA        ......Given:

\dfrac{BS}{SA}=\dfrac{BT}{TC} ...Basic Proportionality Theorem

Substituting the values we get

\dfrac{10}{SA}=\dfrac{9}{2.7}\\\\SA=\dfrac{27}{9}=3\\\\\therefore SA =3\ ft

Therefore the length of SA is 3 ft.
