Answer:
a concave lens is exactly the opppostie with outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.
Step-by-step explanation:
33 degrees,
90-57=33
complementary angles mean that together, the angles add up to equal 90 degrees
Answer:
the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles
Step-by-step explanation:
The computation of the number of miles travelled in four hours in the case when she travelled same miles number each hour is shown below:
= Number of miles × given number of hours
= 60 miles × 4 hours
= 240 mile
Hence, the number of miles travelled in four hours in the case when she travelled same miles number each hour is 240 miles
Answer:
4.9
Step-by-step explanation:
Plug in 13 and 2 for each variable separately to get 0.7(13) - 2.1(2). 0.7 multiplied by 13 equals to 9.1 and 2.1 multiplied by 2 equals 4.2. Subtract 4.2 from 9.1 to get your final answer which is 4.9.
