Please can you help me it said I am in high school but I am in middle school but please help.

C. 58.18

Step-by-step explanation:

The average speed means we will do miles per hour (mph). So if there are 640 miles for 11 hours the fraction would look like this:

640/11

We want to find the value for 1 hour so we need the bottom number(denominator) to be 1

Therefore we divide by 11 on the numerator and denominator by 11

58.181818(repeating)/1

This means we travel 58.181818... miles per hour.

If we round to the hundredths place we get 58.18 or option C.

Keep in mind that we can do this in ratio form and still get the same

miles: hours

640:11

58.181818:1

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.
