Answer: 174 red chips
Step-by-step explanation:
A bag contains a total of 300 red chips and white chips. A student chooses a chip out of the bag, then records the color, and places the chip back in the bag. By doing this, the student recorded 29 red chips and 21 white chips.
To predict the number of red chips in the bag using this method goes thus:
Number of red chips picked= 29
Number of white chips picked= 21
Total number of chips= 29+21 = 50
So, the student picked 29/50. Out of 300 chips, number of reds that will be picked will be:
= 29/50 × 300
= 29 × 6
= 174 red chips
We know the number of faces and vertices of the solid and we have to calculate the number of edges.We have : F = 16 and V = 14.The formula is:F - E + V = 216 - E + 14 = 216 + 14 - 2 = EE = 30 - 2E = 28Answer: The solid has 28 edges.
the false statement is: the absolute value of a number can be negative.
the absolute value of a number is never negative
9x-7=-7
9x=o
x=0
so the answer....is 0
Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5
