Answer:
(328i + 82) / 17
Step-by-step explanation:
`(2i(4+5i)(4-5i))/(4+i)
= (2i(16 - 25i^2)) / (4 + i)
= (2i( 16 + 25) )) / (4 + 1) [Note:- i^2 = -1]
= 82i / (4 + i)
= 82i(4 - i) / (4 + i)(4 - 1)
= 328i + 82 / (16 - i^2)
= (328i + 82) / 17
It's just a variable in a problem. You solve for ex . So whatever your answer is you equal to x.
4+(((2*2*2)-5)*2)=10
(4+((2*2*2)-5))*2=14

Answer:
C. 32 ft tall, 1.2 ft wide
Step-by-step explanation:
A scale of 1 : 50 means the model dimensions are 1/50 of the actual dimensions. The model width will be (60 ft)/50 = 1.2 ft . . . . matches choice C.
The model height will be (1600 ft)/50 = 32 ft. (also matches choice C)
Answer:
Part 1: 4.5
Part 2: 20%, 0.2
Step-by-step explanation:
1. 1.8 = 80% We need to understand this.
So we can do this then:
2. 1.8/8 = 80%/8
3. 0.225 = 1%
4. 0.225 * 20
5. 4.5
(this is part 1 btw)
<u>Part 2!</u>
20% since 100-80 is 20.
20% -> 0.2
