6.5/40.3 = m/12.4
Cross multiply
40.3m = 6.5 x 12.4
40.3m = 80.6
Divide through by 40.3
m = 80.6/40.3
m= 2

m= 2

Which equation represents the area of the triangle? A) A = 1 2 (AC)(AB)(sin A) B) A = 1 2 (AC)(BC)(sin A) C) A = 1 2 (BC)(BD)(si
Juliette [100K]

Answer:

The correct option is A.

Step-by-step explanation:

Let the vertices of the triangle be ABC.

Draw a perpendicular on AC from B. The height of triangle is represented by the altitude from B.

\sin A=\frac{BD}{AB}

AB\sin A=BD

Area of the triangle is

A=\frac{1}{2}\times base\times height

A=\frac{1}{2}\times (AC)\times (BD)

A=\frac{1}{2}\times (AC)\times (AB)\sin A

A=\frac{1}{2}(AC)(AB)\sin A

Therefore option A is correct.

Jay is letting her bread dough rise. After three hours, her bread dough is 11/5 of its original size.
mojhsa [17]

Answer:

original size of Jay's bread dough is raised to 220%

Step-by-step explanation:

Let 1 be the original size of the bread

her bread dough is 11/5 of its original size.

1* \frac{11}{5} = 2.2

The original size of the bread is raised to 2.2

To get percentage we multiply by 100

2.2*100 = 220%

original size of Jay's bread dough is raised to 220%

Opal walked from school to home, which
lianna [129]

Answer:

Slope = -4

x intercept = 3

Step-by-step explanation:

See attachment for graph

Required

a. Determine the slope

b. Find the x intercept and explain what it represents

a. The slope

To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.

(x_1,y_1) = (3,0)

(x_2,y_2) = (0,12)

Next, we calculate the slope (m)

m = \frac{y_1 - y_2}{x_1 - x_2}

m = \frac{0 - 12}{3 - 0}

m = \frac{- 12}{3}

m = -4

b. The x intercept

This is the point where y = 0.

From the graph.

x = 3  when y = 0

This implies that:

After 3 hours, the distance left to cover is 0miles.

In other words, she arrived home in 3 hours
