Which sentence is not correctly written? the conveyor broke down. the packaging machine quit. production was halted at the packaging machine. downtime was do to a problem with the conveyor.

Downtime was do to a problem with the conveyor.

Explanation:

This is the sentence that contains a mistake. In this sentence, the author wrote the word "do" instead of the word "due." The first one is a verb and it refers to taking some action (to do something). "Due to" on the other hand, is an idiom that means "attributable to" or "because of." These words are homophones. Homophones are words that are pronounced the same but have different meanings, and sometimes spelling.

right angles are formed by perpendicular lines. if the lines would extend, to make two intersecting lines, they would form four right angles.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
