The first box is "none of these" since it is not a vertical angle, is not an adjacent angles, and is not a linear pair, the second box is vertical angles
Answer:
1050 masks per person.
Step-by-step explanation:
1) Create an equation to find the total number of masks
2) Solve equation and divide total by 2 to get the number of masks that can be given to both Mark and Paula so that they have equal number.
1) Since Paula has 70% of the total masks, it can be represented as 0.7 * t where t is the variable representing the total number of masks. Mark on the other hand has the remaining number of masks out of 100% which is 30%. We can express that as 0.3. We multiply that by t because he has 30% of the masks. The final equation we have is 0.3t + 840 = 0.7t. 840 because Paula has 840 more masks than Mark.
2) Solve by subtracting 0.3t from both sides leaving you with 0.4t = 840. We divide both sides by 0.4 to get 2100. That is the total number of masks. If we divide that number by 2, we get 1050.
So you basically add all the numbers together multiply them by 100& divide by 54
Hello!

as a fraction.
0.344 = 0.344/1
The 4 is in the thousandths place. Multiply both the numerator and the denominator by 1000.
0.344 × 1000 = 344
1 × 1000 = 1000
This gives us: 344/1000
It's fraction form can be reduced. Simply divide both the numerator and the denominator by 8:
344 ÷ 8 = 43
1000 ÷ 8 = 125
