One cell phone company offers a plan that costs $23.99 and includes unlimited night and weekend minutes. Another company offers a plan that costs $17.99 and charges $0.35 per minute during nights
and weekends. For what numbers of night and weekend minutes does the second company's plan cost
more than the first company's plan?

18 minutes

Step-by-step explanation:

Plan one: 23.99

Plan two: 17.99+(0.35x). X equals charge per minute at night and weekends.

We can subtract our main payment plans that don’t include variables, 23.99-17.99=6. We can then divide by our constant... 6/0.35 to get 17.14... minutes. so we can round up to 18 mins.

To make sure we are correct we can do,

17.99+(0.35)(18) to get 24.29 which is greater than 23.99.

MARK ME AS BRAINLIEST PLEASE!!!

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.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
