Answer:

308 Calories

Step-by-step explanation:

So we start off with 280 as usual, but I will focus on the percent. The given percent is 110% "effort". What we would need to do here is, Firstly, change the percent into a decimal, and this is done by moving the decimal spot of 110%. What I mean is that 110.% and you move that little period over 2 times to the left and also remove the percent as for now because we will not need it. After that you would get 1.10. This is what we will multiply by. So if we did 280x1.10 it equals 308, and that is how I got 308

Hope this helps!

Answer:

This is proportional

Step-by-step explanation:

Your slope is 2 each time. To find slop you do rise/run. go to a dot and go up 2 and over 1. Simplify that and you get a slope of 2. Keep doing that for each point then you can determine if it is proportional or not. In this case it is. Hope this helps :)

Find the area of this shape
Stolb23 [73]

Answer:

171.06 cm²

Step-by-step explanation:

<u>First let us find the area of the circle</u>

Area = π r²

        =  π × 8 × 8

        =  π × 64

        = 201.06 cm²

<u>Now let us find the area of parallelogram</u>

Area = Base × Height

        = 6 cm × 5 cm

        = 30 cm²

<u>And now we have to find the area of the shape when the parallelogram is cut from it</u>

<em>For that, you have to subtract the area of the parallelogram from the area of the circle.</em>

Let us solve now.

Area of the shape = Area of the circle - Area of the parallelogram

                               =  201.06 cm² - 30 cm²

                               =  171.06 cm²

<u></u>

<u></u>

Hope this helps you :-)

Let me know if you have any other questions :-)

Have a nice day !!
