Answer:

\frac{17}{120}

Step-by-step explanation:

Given: An angle measures 51 degrees

To find: fraction of a circle by which the angle turn

Solution:

Angle at the centre in a circle is equal to one complete angle i.e., 360^{\circ}

Measure of an angle =51^{\circ}

Therefore,

Fraction of a circle by which the angle turn = Measure of an angle/ Angle at the centre in a circle \frac{51^{\circ}}{360^{\circ}}=\frac{17}{120}

Solve for D <br><br><br><br><br><br> Thanks!!
Verizon [17]

Answer:

The answer is d = C/pi.

Step-by-step explanation:

To solve this equation for the variable d, we must isolate it on the right side of the equation.  It is currently being multiplied by pi, so to reverse this action, we should divide both sides of the equation by pi.

c = (pi) * d

c/pi = pi/pi * d

c/pi = d

d = c/pi

Therefore, the answer is d = C/pi.

Hope this helps!

I need help ASAP middle school work.
Arturiano [62]

Answer:

B

Step-by-step explanation:

For 11  1/2 gallons, he paid $36.80.

We need to find the cost per gallon.

First, converting 11  1/2 gallons to decimal, it is:

1/2 = 0.5

So, 11  1/2  is  11.5 gallons

So, Cost Per Gallon (last week) = \frac{36.80}{11.5}=3.2

There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.

<em>5% = 5/100 = 0.05</em>

<em>0.05 * 3.20 = 0.16</em>

<em>So,</em>

<em>3.20 + 0.16  = $3.36 per gallon</em>

<em />

Cost Per Gallon (this week) = $3.36

To buy 9  1/4 gallons it would take:

3.36*9.25=31.08

<u>Note:</u>  1/4 = 0.25, so 9  1/4 = 9.25

It would cost $31.08  to buy  9.25 gallons this week

Correct answer is B
