On monday morning the temperature was 38°f, but by the afternoon the temperature had risen 22°f. on tuesday morning the temperature had dropped 27°f since monday afternoon, but then rose 10°f by the noon. how many degrees above or below 38°f is the temperature on tuesday at noon?

The temperature on Tuesday at noon was above .

Step-by-step explanation:

We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F.

So the temperature by Monday afternoon will be:

We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.

Since the temperature rose by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.

To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon.

Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was above .

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
