Answer:
101/140
Step-by-step explanation:
<u>Solving in steps:</u>
- -6/15 * 4/7 - (-7)/20 * 4/7 + 3/4 =
- - 2/5 * 4/7 + 7/20 * 4/7 + 3/4 =
- - 8/35 + 7/35 + 3/4 =
- -1/35 + 3*35/4*35 =
- -4/140 + 105/140 =
- 101/140
Answer:
mine is blue
Step-by-step explanation:
because it the color of the sky
To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.
In order to get the answer of that, let's understand first that the question can first be presented as a fraction form. So by breaking down the question, we will be able to get the fraction form which is 300/2530. Now in order to get the percent form of that, we simply divide 300 and 2530. The answer to that will result in 0.11858. Now we know for a fact that in order to make a decimal a percentage, we just have to move the decimal point two times to the right. So the answer is 11.858%
So the first thing you want to do when faced with two fractions with different denominators (when subtracting or adding) is to make the denominators the same. So for this equation they would turn out to be p+10/16=15/16 (because 16 is the lowest common denominator, 8 times two) so then you want to subtract 10/16 from 15/16 to isolate the variable (p) which would get:
p=5/16
This is the final answer because it cannot be simplified.
Hope this helps!
