A line graph is titled “Water Full-Range Spectral Absorption Curve.” The x-axis is titled “Wavelength” and the y-axis is titled “Absorption ( 1 per meter ).” Evenly spaced tick marks on the x-axis denote 10 nanometers, 100 nanometers, 1 micrometer, 10 micrometers, 100 micrometers, 1 millimeter, and 10 millimeters. Evenly spaced tick marks on the y-axis denote 10 superscript negative two, 10 superscript negative one, 10 superscript zero, 10 superscript one, 10 superscript two, 10 superscript three, 10 superscript four, 10 superscript five, 10 superscript six, 10 superscript seven, and 10 superscript eight. Above the graph, horizontal lines indicate the range of wavelengths for U V, V I S, near I R , mid I R , far I R , and E H F. The graph contains one line that begins at 10 nanometers and a little more than 10 superscript six. Moving from left to right, this line ascends gradually until it reaches a point near 100 nanometers and 10 superscript eight. From this point, the line steeply descends to a point a little more than halfway between 100 nanometers and 1 micrometer, and slightly more than 10 superscript two. This point indicates the end of the range labeled “U V” and the beginning of the range labeled “V I S.” The range labeled “V I S” is shaded with a color spectrum including the full range of Roy G Biv colors. Here, the line briefly descends in the same path as before, and then steeply ascends to a point near 1 micrometer and 10 superscript zero. This point indicates the end of the range labeled “V I S” and the beginning of the range labeled “near I R.” The line continues its steep ascent, with short, abrupt descents in between, until it reaches a point a little more than halfway between 1 micrometer and 10 micrometers, and a little more than 10 superscript six. This point indicates the end of the range labeled “near I R” and the beginning of the range labeled “mid I R.” Here, the line moves steeply and sporadically up and down until it reaches a point a little more than halfway between 10 micrometers and 100 micrometers, and slightly more than 10 superscript five. This point indicates the end of the range labeled “Mid I R” and the beginning of the range labeled “Far I R.” The line descends very gradually to a point slightly more than 1 millimeter and slightly more than 10 superscript four. This point indicates the end of the range labeled “Far I R” and the beginning of the range labeled “E H F.” The line continues its gradual descent to 10 millimeters and slightly more than 10 superscript three. This point indicates the end of the range labeled “E H F.”
Water full-range spectral absorption curve. This curve shows the full-range spectral absorption for water. The y -axis signifies the absorption in 1/cm. If we divide 1 by this value, we will obtain the length of the path (in cm) after which the intensity of a light beam passing through water decays by a factor of the base of the natural logarithm e (e = 2.718281828).

Wayne and Dennis like to ride the bike path from Riverside Park to the beach. Dennis’s speed is seven miles per hour faster than Wayne’s speed, so it takes Wayne 2 hours to ride to the beach while it takes Dennis 1.5 hours for the ride. Find the speed of both bikers.

from theory: distance [miles] = speed [mph] × time [hours] info #1 speed_Dennis × 1.5 = speed_Wayne × 2 => speed_Wayne = 0.75 × speed_Dennis (i) info #2 speed_Dennis = speed_Wayne + 7 [mph] (ii) use (i) in (ii) => [...] speed_Dennis = 28 mph speed_Wayne = 21 mph
George
Let W be Wayne's speed in miles per hour and D be Dennis's speed in miles per hour. We know that W + 7 = D and W * 2 = D * 1.5. Substituting the first equation into the second: W * 2 = (W + 7) * 1.5 W * 2 = W * 1.5 + 7 * 1.5 0.5 * W = 7 * 1.5 W = 7 * 3 or 21 W is 21 D = W + 7 D = 21 + 7 D = 28

Shakir works at a computer store. His weekly pay will be either a fixed amount, $925, or $500 plus 12% of his total sales. How much should his total sales be for his variable pay option to exceed the fixed amount of $925.
mahnoor Reply
I'm guessing, but it's somewhere around $4335.00 I think
Lewis
12% of sales will need to exceed 925 - 500, or 425 to exceed fixed amount option. What amount of sales does that equal? 425 ÷ (12÷100) = 3541.67. So the answer is sales greater than 3541.67. Check: Sales = 3542 Commission 12%=425.04 Pay = 500 + 425.04 = 925.04. 925.04 > 925.00
