Solve the following word problem by using a system of equations.
jake and his friends went to the carnival. the total number of ice cream sandwiches and sodas purchased among all of them was 18. one ice cream sandwich costs $2.25 and a soda costs 75¢. in total, $30.00 was spent on ice cream and soda.
which statement is true?
a. jake went to the carnival with 8 of his friends.
b. jake and his friends bought a total of 11 ice cream sandwiches.
c. jake and his friends bought a total of 11 sodas.
d. jake and his friends spent more on sodas than ice cream sandwiches.

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.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

i wish i could you, i have no idea how to answer this
