Karl has stamps in his desk drawer. The possible combinations of stamps are shown below. A 2-column table with 5 rows. The first column, the number of 45-cent stamps, has the entries 18, 20, 22, 25. The second column, the number of 65-cent stamps, has the entries 17, 15, 13, 10.
Which statement about the stamps is correct?

The total number of stamps is 25.
The total value of the stamps is $18.75.
The total number of stamps is 35.
The total value of the stamps is $19.15.

Letter C

correct!

Step-by-step explanation:

20 + 15 = 35

22 + 13 = 35

25 + 10 = 35

so the answer is 35

correct!

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
