Answer:
D
Step-by-step explanation:
Using process of elimination we know that it cannot be a,b or c because after you add the 2 new stamps james collected the ratio is 8:12 which cannot be 1:2 because 8 is not half, can't be B because 8 is less than 12, Also cannot be C because 8 is less than 12
125 is the answer.
A mean of vie numbers is 25. If it is 25, the numbers must be 25. So, since there is 5 of 25, multiply 25 by 5. Then, the answer would be 125.
There is also another way to do it. Set-up your equation.
x/5=25.
Now flip it to make the equation a multiplication problem.
25×5=x
Once you solve the equation, you should get 125 is the answer.
Answer:
126mm
Step-by-step explanation:
To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.
There are 4 circles = 18mmx4=72mm
Add on the 3x strips = 72+(18x3) = 126mm.
Hope this helps
Answer:
Step-by-step explanation:
You have to use the triangle inequality theorem:
12cm, 4cm, xcm
x > 4cm - 12cm
x > -8cm
x < 12cm - 4cm
x < 8cm
-8cm < x < 8cm
