X * 1.085 = 19.18
solve for x
Why is this how you figure it out? well... you have the price of the CD cover and the total is the price of the CD cover with tax.
Price of the CD cover would be: x * 1 = price of cd cover
Put that tax on there: x * 1.085 = price of cd cover with tax
why .085? move that decimal over two places to the left from the 8.5%
Answer:
Tiles won't be enough
Step-by-step explanation:
The perimeter of the area :
2(length + Width)
Given dimension = 6.4 by 2.7 feets
Perimeter = 2(6.4 + 2.7) = 18.2 feets
1 feet = 12 inches
Perimeter = 18.2 * 12 = 218.4 inches
1 tile = 6 inches
30 tiles = 6* 30 = 180 inches
Since the perimeter of the area is greater Than the 180, then we can conclude that the tiles won't be enough
70 ÷100 ·200 = 140 thats your answer
Answer:
3 acute angles with different measures and 1 right angle and 2 acute angles with same measures
Answer:
Step-by-step explanation:
From the first image attached below, we will see the sketch of the curve x = y² & x = 2y
In the picture connected underneath, the concealed locale(shaded region) is bounded by the given curves. Now, we discover the marks of the crossing point of the curves. These curves will cross, when:
Thus, the shaded region fall within the interval 0 ≤ y ≤ 2
Now, from the subsequent picture appended we sketch the solid acquired by turning the concealed region about the y-axis.
For the cross-sectional area of the washer:
Finally, the volume of (solid) is:
![V = \int^2_0 A(y) \ dy \\ \\ V = \int^2_0 \pi (4y^2 -y^4) \ dy \\ \\ V = \pi \int^2_0 (4y^2 -y^4) \ dy \\ \\ V = \pi \Big[\dfrac{4}{3}y^3 - \dfrac{y^5}{5} \big ] ^2_0 \\ \\ V = \pi \Big [ \dfrac{4}{3}(2)^3-\dfrac{2^3}{5} \Big ] \\ \\ V = \dfrac{64}{15}\pi \\ \\ V = (4.27 ) \pi](https://tex.z-dn.net/?f=V%20%3D%20%5Cint%5E2_0%20A%28y%29%20%5C%20dy%20%5C%5C%20%5C%5C%20%20V%20%3D%20%5Cint%5E2_0%20%5Cpi%20%284y%5E2%20-y%5E4%29%20%5C%20dy%20%20%5C%5C%20%5C%5C%20V%20%3D%20%5Cpi%20%5Cint%5E2_0%20%284y%5E2%20-y%5E4%29%20%5C%20dy%20%20%5C%5C%20%5C%5C%20V%20%3D%20%5Cpi%20%5CBig%5B%5Cdfrac%7B4%7D%7B3%7Dy%5E3%20-%20%5Cdfrac%7By%5E5%7D%7B5%7D%20%20%20%5Cbig%20%5D%20%5E2_0%20%5C%5C%20%5C%5C%20%20V%20%3D%20%5Cpi%20%5CBig%20%5B%20%5Cdfrac%7B4%7D%7B3%7D%282%29%5E3-%5Cdfrac%7B2%5E3%7D%7B5%7D%20%5CBig%20%5D%20%20%5C%5C%20%5C%5C%20%20V%20%3D%20%5Cdfrac%7B64%7D%7B15%7D%5Cpi%20%20%5C%5C%20%5C%5C%20V%20%3D%20%284.27%20%29%20%5Cpi)
