Answer:
A) 41.9
Step-by-step explanation:
The formula I use is π(pi)r(radius)^2h(height)/3, so it looks like πr^2(h/3) and I used that and I got 41.88 which rounds to 41.9 or A
A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4
A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===
The final discounted price is $18.6
Step-by-step explanation:
In this problem we have to decrease the value of $20 by 7%.
First of all, we have to calculate the 7% of $20. We can do it as follows:
![d=\frac{7}{100}\cdot 20 = 1.4](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B7%7D%7B100%7D%5Ccdot%2020%20%3D%201.4)
This means that the 7% of $20 is 1.4$.
Now we want to decrease the original value by 7%, so we calculate the difference:
![f=20 - d = 20-1.4=18.6](https://tex.z-dn.net/?f=f%3D20%20-%20d%20%3D%2020-1.4%3D18.6)
So, the final discounted price is $18.6

So just find the factors of 90
90=2 times 3 times 3 times 5
so the factors could be
2,3,15
2,9,5
6,3,5
10,3,3
there are 4our
Answer:
5
Step-by-step explanation:
(4+4y)/3 = x 4+4y+4y = 4+8y=16 12=8y 12/8= 6/4 = 3/2 y= 1.5(4) = 6 +4 = 10
3x=10 10/3 = x x*y = 1.5 times 10/3 = 5
