What Is The Area Of This Triangle?A=bh2a-54 Cmb-90 Cmc-108 Md-216 M

Answers

Answer 1

Answer:

a

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 9 and h = 12 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

Answer 2
It’s a because 12x9=108 then divide it by 2 and you have 54

Answer:

y = -5/2x +4

Step-by-step explanation:

First, make the equation into standard form.

5x + 2y = -10

2y = -5x - 10

y = -2.5x - 5

In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)

The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)

In y = -2/5x - 8, the slope is -2/5

In y = 2/5x + 7, the slope is 2/5

In y = 5/2x - 6, the slope is 5/2

In y = -5/2x +4, the slope is -5/2.  

Thus, y = -5/2x +4 is the right answer

Answer:

Problem 1: y = 4x + 6

Problem 2: 48 soda bottles per minute

Step-by-step explanation:

Problem 1:

Equation of a line in slope-intercept form is given as y = mx + b.

Wee have to figure out the value of the slope (m) and the value of y-intercept (b). Them to write an equation that represents the line of the graph, we need to input the values of m and b into the equation, y = mx + b.

Thus,

m = hourly fee = $4

b = initial deposit = $6

Substitute m = 4 and b = 6 into y = mx + b

Equation would be:

y = 4x + 6

Problem 2:

What we are simply asked to do is to find the slope of the line, which is the number of soda bottles the machine will produce per minute

Using the two points (3, 144) and (8, 384),

Slope = ∆y/∆x = (384 - 144)/(8 - 3)

Slope = 240/5 = 48

Thus, the machine will make 48 bottles per minute

Answers

Answer:

the missing length is 14 feet.

Step-by-step explanation:

a = L × W

168ft² = 12 × W     - divide both sides of the equation by 12

                             - 168 ÷ 12 = 14

Since this is a test/homework I'll give a hint.

For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.
