At a concession stand, 3 hot dogs and 4 hamburgers cost $11.50; 4 hot dogs and three hamburgers cost $11.25 find the cost of one hot dog and the cost of one hamburger. what is the cost of one hot dog?

around 1.64

Step-by-step explanation:

Well if you add the number of hamburgers and hotdogs together you get 7 which when divided you get 1.6428 and when you multiply that by 7 you get 11.48 and when rounded is 11.50 ( I don’t know if that is fully correct but I tried)

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:

4+4+2x

or

2x+8
