The guessing strategy only works when you don’t u don’t understand a question so I advise you NOT to do it , only when it’s necessary but the Estimation strategy works when you don’t have a any but a answer where theirs decimals or a answer that is close to one another and can be rounded

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.
bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc  AC : circumference C = angle at centre of sector : 360°

\frac{AC}{C} = \frac{123}{360} , that is

\frac{4}{C} = \frac{123}{360} ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = \frac{1440}{123} ≈ 11.71 cm ( to the nearest hundredth )

. Roger uses his truck to plow parking lots when it snows. He wants to find a model to predict the number of service calls he ca
expeople1 [14]

Answer:

4.1 calls

Step-by-step explanation:

The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

c(s)=0.8s+0.29

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

c(4.7)=0.8*4.7+0.29\\c(4.7)=4.05\ calls

Rounding to the nearest tenth, Roger will get about 4.1 calls.
