What is the area of the cross section AFGD?

hjlf

Answer: The area is $15in^2$

Step-by-step explanation:

The cross section AFGD is a rectangle. Then, its area can be calculated with this formula:

$A=l*w$

Where:

"A" is the area of the rectangle.

"l" is the lenght of the rectangle.

"w" is the width of the rectangle.

Then, from the figure, you can identify that the dimensions of the rectangle AFGD are:

$l=5in\\w=3in$

Therefore, you can substitute these values into the formula $A=l*w$ to find the area of the cross section AFGD. Then, you get:

$A=(5in)(3in)\\A=15in^2$

to raise money for her school field trip, Jane is selling candles. She has a large cancel for $8, and a small candle for $5. If

Fed [463]

Answer:

45 large candles
53 small candles

Step-by-step explanation:

Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...

8c +5(98-c) = 625

3c + 490 = 625 . . . . . . eliminate parentheses, collect terms

3c = 135 . . . . . . . . . . . . subtract 490

c = 45 . . . . . . . . . . . . . . divide by 3

Jane sold 45 large candles and 98-45 = 53 small candles.

a hiking path is represented by the equation y=3/8x on a coordinate map. The county would like to create a parallel path for bik

stepladder [879]

Answer:

The equation of the bike path on a coordinate map is represented by $y = \frac{3}{8}\cdot x +1$ .

Step-by-step explanation:

From Analytical Geometry, we know that resultant parallel line is a translated version of parent line. Two lines are parallel to each other when they share the same slope. The resultant line can be construted from slope-point form:

$y-y_{o} = m_{\parallel}\cdot (x-x_{o})$

Where:

$x_{o}$ , $y_{o}$ - Components of known point, dimensionless.

$m_{\parallel}$ - Slope of the parallel line, dimensionless.

In addition, a line has also this form:

$y = m\cdot x + b$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$m$ - Slope, dimensionless.

$b$ - y-Intercept, dimensionless.

Given that parent function is $y = \frac{3}{8}\cdot x$ , the slope of the resulting line is $m_{\parallel} = \frac{3}{8}$ . Now, if $x_{o} = 16$ and $y_{o} = 7$ , we obtain the equation of the line:
