Plsss help!!!!!!! #3 #4

AVprozaik [17]

Answer:

3) 162 ft² || 4) 38.25 mm²

Step-by-step explanation:

area of triangle = 0.5 * base * height

= 0.5 * 27 * 12

= 162 ft²

4) area of triangle = 0.5 * base * height

= 0.5 * 8.5 * 9

= 38.25 mm²

Line m has the equation y = 1/2x - 4

Mandarinka [93]

Answer:

As the slopes of both lines 'm' and 'n' are the same.

Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.

Step-by-step explanation:

We know that the slope-intercept of line equation is

$y=mx+b$

Where m is the slope and b is the y-intercept

Given the equation of the line m

y = 1/2x - 4

comparing with the slope-intercept form of the line equation

y = mx + b

Therefore,

The slope of line 'm' will be = 1/2

We know that parallel lines have the 'same slopes, thus the slope of the line 'n' must be also the same i.e. 1/2

Checking the equation of the line 'n'

$x-2y=4$

solving for y to writing the equation in the slope-intercept form and determining the slope

$x-2y=4$

Add -x to both sides.

$x - 2y + (-x) = 4+(-x)$

$-2y = 4 - x$

Divide both sides by -2

$\frac{-2y}{-2}=\frac{-x+4}{-2}$

$y=\frac{1}{2}x-2$

comparing ith the slope-intercept form of the line equation

Thus, the slope of the line 'n' will be: 1/2

As the slopes of both lines 'm' and 'n' are the same.

Therefore, we conclude that the equation x-2y=4 represents the equation of the line 'n' if lines m and n are parallel to each other.

Bob is buying coffee for his coffee machine.Option 1 is $5.99 for 12 coffeesOption 2 is 23.99 for 70 coffee Which is the better

velikii [3]

Step 1: Let's review the information provided to us to answer the problem correctly:

• Option 1: $5.99 for 12 coffees

• Option 2: $ 23.99 for 70 coffee

Step 2: Let's calculate the cost of a coffee in each option, as follows:

• Cost of a coffee in Option 1 = 5.99/12 = 0.50 (rounding to the next cent): This means that every cup of coffee costs $ 0.50

• Cost of a coffe in Option 2 = 23.99/70 = 0.34 This means that every cup of coffee costs $ 0.34

Step 3: Now we can decide which is the better deal and why.

The better deal is option ........ because it is cheaper than option..........

You can complete step 3, Kay.
