Answer:
86 cm.
Step-by-step explanation:
If we add 1 more triangle to one in the picture we that:
If we place 6 triangles together the perimeter will be 6 + 2 = 6
for 8 triangles the perimeter is 10 .
For 84 the perimeter will be 86 cm.
Answer:
Jerry has 9 action figures.
Step-by-step explanation:
Since Tom has three times as many action figures as Jerry, Tom has 3x action figures, where x is the number of action figures that Jerry has.
Since Tom has 27 action figures, we can say that <u>3x=27</u>.
3x=27
x=9
Answer:
by drawing a number line then simpifly 3/2 than mark it down
Step-by-step explanation:
Answer:
The value of x is 9.
The value of y is 18.
Step-by-step explanation:
The given triangle is a right angled triangle.
We have: 
Therefore, 
Since, 
Therefore, we have:
Now, 'y' is the hypotenuse.
Use Pythagoras theorem, we have 
Substituting x = 9, we get:
81 + 81(3) = y²
Hence, the value of y = 18.
Answer:
15
Step-by-step explanation:
30% is equal to 0.3 as a proportion
