Okay, i went with a rectangle, if the rectangle base is 12 and the height is 6 then it would be 12*6 + 12*6 + 12*6= 216 now the ratio is easy , 72:72 because that's what makes up the 12*6 and because there is 3 it's 72 two times now for part b 5 x 10 so that is the height and length so now what you want to do is do what you did the second time so it would be 72:50.
Extra tips: To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.
Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.
Step-by-step explanation:
The perimeter of a polygon is the sum of all of the polygon's sides. Here, a rectangle has 4 sides:
Perimeter of Rectangle
= 2 + (4x - 3) + 2 + (4x - 3)
= (8x - 2)cm.
Y3 = y x 3 = 4 x 3 = 12
4z = 4 x z = 4 x 6 = 24
12 + 24 - 16
Im using PEMDAS I’m not sure if you use another order of operations if you do just do the expression your way
12 + 24 = 36
36 - 16 = 20
A. 20
Answer:
See explanation below
Step-by-step explanation:
If the base of a radical exponent is the same then the following properties hole and x≠ 0
![\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D)
= 
Rule 1
Rule 2
Rule 3
The numerator in the expression is
![\sqrt[3]{x^2y^5} =(x^2)^\frac{1}{3} (y^5)^\frac{1}{3} = x^\frac{2}{3}} . y ^ \frac{5}{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E2y%5E5%7D%20%3D%28x%5E2%29%5E%5Cfrac%7B1%7D%7B3%7D%20%28y%5E5%29%5E%5Cfrac%7B1%7D%7B3%7D%20%3D%20x%5E%5Cfrac%7B2%7D%7B3%7D%7D%20.%20y%20%5E%20%5Cfrac%7B5%7D%7B3%7D)
Using rules 1 and 3
The denominator is
![\sqrt[4]{x^3y^4} =(x^3)^\frac{1}{4} (y^4)^\frac{1}{4} = x^\frac{3}{4}} . y ^ 1}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E3y%5E4%7D%20%3D%28x%5E3%29%5E%5Cfrac%7B1%7D%7B4%7D%20%28y%5E4%29%5E%5Cfrac%7B1%7D%7B4%7D%20%3D%20x%5E%5Cfrac%7B3%7D%7B4%7D%7D%20.%20y%20%5E%201%7D)
Using rules 1 and 3
Therefore the original expression in exponent form is
Using rule 2 we get the final expression as
2/3 - 3/4 = 8/12 - 9/12 = -1/2
5/3 - 1 = 5/3 - 3/3 = 2/3
So the final expression is
