Sophia has $20. she buys a hair band for $3.99, gum for $1.29, and a brush for $6.75. not including tax estimate how much change she should receive. show your work

First I would add $3.99, $1.29, and $6.75 to see the total amount she spent.

3.99 + 1.29 + 6.75 = 12.03

She spent a total of $12.03. Now, subtract this amount from $20 to get your answer.

20 - 12.03 = 7.97

She should receive $7.97 in change.

I hope this helps!

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
