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

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.
