Jim decided to go for a drive in his car. He started out at 0 miles per hour (mph). He then

accelerated 20 mph down his street. Then, to get on the highway he accelerated another 35 miles

per hour. A car was going slow in front of him so he slowed down 11 mph. He then got off the

highway, so he slowed down another 7 mph. At what speed is he driving?

4 Miles per hour.

Step-by-step explanation:

Since he slowed down to 11 MPH at the slow car, We cab then use that as a baseline. They turned off the highway and slowed another 7 MPH, so we just subtract 7 from 11 to get 4 MPH.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

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:
