Answer:
336
Step-by-step explanation:
8 (12 + 30)
Follow PEMDAS order of operations.
Calculate within parentheses. (12 + 30)
12 + 30
12 + 30 = 42
= 42
=8 * 42
Multiply and divide left to right
8 *42
8 * 42 = 336
= 336
Answer:
![W =2 {y}^{3} \: \:meters](https://tex.z-dn.net/?f=W%20%3D2%20%7By%7D%5E%7B3%7D%20%20%5C%3A%20%20%5C%3Ameters)
Step-by-step explanation:
The figure is a rectangle whose area can be calculated from the relation;
![A = L \times W](https://tex.z-dn.net/?f=A%20%3D%20L%20%5Ctimes%20W)
where A , L and W represent the area, length and width respectively.
From the question,
![A = 60 {y}^{4}](https://tex.z-dn.net/?f=A%20%3D%2060%20%7By%7D%5E%7B4%7D%20)
and L=30y meters
We substitute the values of A and L into the formula to solve for W
![\implies60 {y}^{4} = 30y \times W](https://tex.z-dn.net/?f=%20%5Cimplies60%20%7By%7D%5E%7B4%7D%20%3D%2030y%20%5Ctimes%20W)
Dividing through by 30y
![\implies\frac{60 {y}^{4}}{30y}= \frac{30y \times W}{30y}](https://tex.z-dn.net/?f=%5Cimplies%5Cfrac%7B60%20%7By%7D%5E%7B4%7D%7D%7B30y%7D%3D%20%5Cfrac%7B30y%20%5Ctimes%20W%7D%7B30y%7D%20)
![\implies W =2 {y}^{3} \: \:meters](https://tex.z-dn.net/?f=%5Cimplies%20W%20%3D2%20%7By%7D%5E%7B3%7D%20%20%5C%3A%20%20%5C%3Ameters)
NB: From the law of indices;
![\frac{ {y}^{4} }{y}= {y}^{(4 - 1)}={y}^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7By%7D%5E%7B4%7D%20%7D%7By%7D%3D%20%20%7By%7D%5E%7B%284%20-%201%29%7D%3D%7By%7D%5E%7B3%7D%20)
Answer:
1 : 3
Step-by-step explanation:
1st Half: 9
2nd Half: 2(9)
Ratio = 2nd : 1st+2nd
9 : 9+2(9)
9 : 9 + 18
9 : 27
1 : 3
