Answer:

PB=5

Step-by-step explanation:

Since you know that BD=24, you also know that both segments BC and CD have the same value since they're congruent: 12. You also were given the value of PC. Using Pythagorean Theorm, Substitute 12 for a and 13 for c, so the equation would say

12^2+b^2=13^2

Simplify to get

144+b^2=169

Now subtract 144 from 169 and you get 25. That is b^2. All you have to do now is square root 25 to isolate b.

√25=5

So therefore,

b=5

Tonia and trinny are twins. Their friends give them identical cakes for their birthday. Tonia eats 1/8 of her cake and trinny ea

Nikitich [7]

Answer:

$\frac{7}{12}$ of the cake

Step-by-step explanation:

add $\frac{1}{8}$ and $\frac{1}{6}$ to see the total amount of cake eaten.

a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24

b. multiply accordingly to get the correct numerator: $\frac{3}{24}$ + $\frac{4}{24}$

c. add: $\frac{3}{24}$ + $\frac{4}{24}$ = $\frac{7}{24}$

subtract found value from total to find left over cake.

a. 24 - 7 = 14

simplify.

a. $\frac{14}{24}$ = $\frac{7}{12}$

You are left with $\frac{7}{12}$ of the cake.
