Which statement is true? A minute is 60 times as long as an hour.

A minute is 60 times as long as a second.

A second is 60 times as long as an hour.

An hour is 60 times as long as a second.

A minute is 60 times as long as a second.

Step-by-step explanation:

There are 60 minutes in a second.

1 hr = 60 mins

1 min = 60 secs

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
