Answer:

# of granola bars and it's cost.

Step-by-step explanation:

It is asking for the meaning of 2B. Note that inside the question, it states that:

"<em>The price of a granola bar is B dollars</em>".

It also states that:

"<em>Donovan eats </em>2<em> granola bars</em>".

This means that to solve for the total spent on granola bars, you multiply the price (B) with the amount gotten (2 in this case).

42.54 is the same as 42 _____' 24".
torisob [31]

Answer:

42.54\°=42\°+32'+24''

Step-by-step explanation:

we have

42.54\°

Remember that

1\ degree=60\ minutes

1\ minute=60\ seconds

in this problem we have

42.54\°=42\°+0.54\°

Convert 0.54\° to minutes

0.54\°=0.54*60=32.4'

so

42\°+0.54\°=42\°+32.4'=42\°+32'+0.4'

Convert 0.4' to seconds

0.4'=0.4*60=24''

therefore

42.54\°=42\°+32'+24''

Using the image, determine the length of each arc.<br> m RC=<br> m CBR =
Montano1993 [528]

<u>Given</u>:

Given that the measure of ∠CDR = 85°

We need to determine the measure of \widehat{RC} and \widehat{CBR}

<u>Measure of arc RC:</u>

Since, we know that if a central angle is formed by two radii of the circle then the central angle is equal to the intercepted arc.

Thus, we have;

m\angle CDR = m \widehat{RC}

Substituting the values, we get;

85^{\circ} = m \widehat{RC}

Thus, the measure of \widehat{RC} is 85°

<u>Measure of arc CBR:</u>

We know that 360° forms a full circle and to determine the measure of arc CBR, let us subtract the values 360 and 85.

Thus, we have;

m\widehat{CBR}=360^{\circ}-m \widehat{RC}

Substituting the values, we have;

m\widehat{CBR}=360^{\circ}-85^{\circ}

m\widehat{CBR}=275^{\circ}

Thus, the measure of \widehat{CBR} is 275°
