Answer:
1 triangle can be formed
Step-by-step explanation:
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.
"Jeannie is 8 years older than her younger sister April"
this translates to
J = A + 8
"added together, their ages equal 198"
this translates to
A + J = 198
Plug the first equation into this one and we get
A + A + 8 = 198
add like terms
2A + 8 = 198
subtract 8 from both sides
2A = 190
divide both sides by 2
A = 190/2 = 95
Therefore April is 95 years old
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
