Answer:
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens,When rounding an integer, all place values to the right of the rounding position are filled with zeros. For example, let's round 8,372 to the hundreds position, which currently contains the number 3. Because the number following the 3 is a 7, we raise the 3 to a 4, and the answer is 8,400.
Answer:
67.5 degrees
Step-by-step explanation:
The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)
We know the 3 angles of a triangle add to 180 degrees
45+x+x = 180
Combine like terms
45+2x=180
Subtract 45 from each side
45-45 +2x = 180-45
2x= 135
Divide by 2
on each side
2x/2 =135/2
x = 67.5
Answer:
y/7=7x/7+2/7
Step-by-step explanation:
Answer:
20 Edges
Step-by-step explanation:
As this figure shows only 10 edges..so to meet the given condition (8 faces; 4 hexagons & 4 triangles) same figure is present at the back making total of 20 Edges.
I believe 10.42 if you add try this if its not on their try dividing by 2
