Multiply the rate per mile by the miles and the appropriate conversion factor.

\dfrac{1.2\,\text{oz}}{1\,\text{mi}}\cdot (15\,\text{mi})\times \dfrac{1\,\text{cup}}{8\,\text{oz}}=\dfrac{1.2\cdot 15}{8}\,\text{cup}=2.25\,\text{cup}

The car leaked 2.25 cups of oil on the trip to grandma's house.

I need help finding the solution

<h3>Answer:  226 degrees</h3>

=====================================================

Explanation:

Notice the tickmarks on the segments in the diagram. This tells us that chords DC and CB are the same distance from the center. It furthermore means that DC and CB are the same length, and arcs DC and CB are the same measure

arc DC = arc CB

12x+7 = 18x-23

12x-18x = -23-7

-6x = -30

x = -30/(-6)

x = 5

---------------------

Use this x value to find the measure of arcs DC and CB

  • arc DC = 12x+7 = 12*5+7 = 67
  • arc CB = 18x-23 = 18*5-23 = 67

We get the same measure for each, which helps confirm we have the correct x value.

The two arcs in question add to 67+67 = 134 degrees. This is the measure of arc DCB. Subtract this from 360 to get the answer

arc DAB = 360-(arc DCB) = 360-134 = 226 degrees

I'm using the idea that (arc DCB) + (arc DAB) = 360 since the two arcs form a full circle.

If a welder completed 136 out of 160 welds so far, what is the percent of welds that has been completed?
MatroZZZ [7]
85%. You take the completed amount and divide it by amount you have in all. Which gives you 136 divided by 160. Which will give you .85 then you move the decimal to give you a percent of 85

Which sum or difference identity would you use to vertify that cos (180⁰- thata)=-cos thata <br>​
astraxan [27]

Step-by-step explanation:

Use the angle difference formula for cosine.

cos(α − β) = cos α cos β + sin α sin β

cos(180° − θ) = cos 180° cos θ + sin 180° sin θ

cos(180° − θ) = (-1) cos θ + (0) sin θ

cos(180° − θ) = -cos θ
