Answer:
1 : 36
Step-by-step explanation:
To obtain the scale factor, the dimensions must be in the same units.
Using the conversion
1 foot = 12 inches, then
15 feet = 15 × 12 = 180 inches, thus
scale factor = 5 : 180 ← divide both parts by 5
scale factor = 1 : 36
Answer:
Step-by-step explanation:
2 1/2
Answer:
second choice
Step-by-step explanation:
The given sums ∑ have j = 1, j = 2, j = 3, j = 4, j = 5
Consider first j = 1 and substitute in the answers to see if we get the first term of the series -3
✅
2·1 - 5 = 2-5 = -3 ✅
3·1 - 6 = 3-6 = -3 ✅
❌
We see that last choice gives us as first term to be 1 not -3 so eliminate that possibility.
Consider now j = 2 and substitute in the answers to see if we get the second term of the series -1
✅
2·2 - 5 = 4-5 = -1 ✅
3·2 - 6 = 6-6 = 0 ❌
We see that third choice gives us as second term to be 0 not -1 so eliminate that possibility.
Consider now j = 3 and substitute in the answers to see if we get the third term of the series 1
❌
2·3 - 5 = 6-5 = 1 ✅
We see that first choice gives us as third term to be -1/3 not 1 so eliminate that possibility.
Now we are left with the second choice as the only possibility.
Answer:
1. 24+40+48+24=136 2. 384
Step-by-step explanation:
for 1- first you find the area of the triangles or whatever you like i did that, together it was 24. then you find the rest of the sides area which are 40, 48, and 24 considering the dimensions. The Volume is 136 cm cubed.
2. 384- you multiply all the numbers together and get 384, pretty self explanatory.
