Answer:
-70
Step-by-step explanation:
Answer: There are 8 edges and 5 verticles
Step-by-step explanation:
This is a square pyramid. The base is 1 face. The sides that are touching the base and touching at the point that the top is 4 faces altogether. 4+1=5 faces. You can also count the number of faces. (1 face is a square (the base) and the other 4 faces are the sides).
Ok vertices are the points. There are 5 points. Points are where edges touch. (4 vertices are touching the square, the last vertice is at the top of the pyramind)
There are 8 edges. Edges are the literal "edges". You can count. The square on the bottom has 4 edges. The edges touching the top point there are 4 edges. There are 8 edges in total. (4 edges are sides of the square, the other edges are pointing to the top of the pyramind)
The first choice is wrong because it does not have 5 faces.
The second one is correct, the figure has 5 vertices and 8 edges.
The third one is wrong because the figure doesn't have 8 vertices
The last one is wrong it does not have 4 faces.
Answer:
83.241
Step-by-step explanation:
To divide by 10, move the decimal point one place left.
832.41 ÷ 10 = 83.241
4k+5+ 6k + 10 = 115
10k + 15 = 115
10k = 100
K = 10°
Usually, you CAN'T turn a fraction into a whole number.
You can ONLY do it when the top number is a multiple
of the bottom number. Otherwise, it's not possible.
IF the top number is a multiple of the bottom number,
then take the bottom number, and divide both the top
and the bottom of the fraction by it. Then the top number
will be the whole number that's equal to the original fraction.
Examples:
12 / 5 . 12 is not a multiple of 5 , so there is
NO whole number that's equal to 12/5 .
5 / 12 . Same thing. 5 is not a multiple of 12 .
12 / 3 . 12 is a multiple of 3 .
Divide top and bottom by 3 .
Then you have 4 / 1 .
4 is the same as 12/3 .
