Bess and gina earn $45 per week for delivering flowers. bess worked for x weeks and earned an additional total bonus of $20. gina worked for y weeks. which expression shows the total money, in dollars, that bess and gina earned for delivering flowers?

First option:

Step-by-step explanation:

The missing options are:

 We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.

According to the data  given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

Since earned an additional total bonus of $20, then the total money in  in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

Notice that this expression matches with the one shown in the first option.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
