40.82 kg beacause one kg is 2.20462 pounds so if you add all that together it all adds up to that.

1 kg = 2.2 lb
to set up your proportion
- put your given over one
90lb / 1
then multiply that by you conversion factor which is 1 kg = 2.2 lb
90lb/1   x   1kg/2.2lb
since you have lb on both the top and bottom that unit would cancel out leaving you with kg
if you multiply straight across you get 90 x 1 = 90 and 1 x 2.2 = 2.2
now you just divide the top number by the bottom number 90 ÷ 2.2 = 40.91 kg

Solving two step equations

First, you would subtract 6 from both sides

-4x+6=-30
      -6  -6
-4x=-36

Then divide both sides by -4 to get x by itself

-4x=-36
-4    -4
x=9

Hope this helps!

Ali earns a weekly salary of $475. She also earns $30 for each computer she sells. Which linear equation represents her total we
Wewaii [24]

Answer:

y=30x+475

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept or initial value

Let

y ----> total weekly pay

x ---> is the number of computers sold in a week

In this problem we have

m=\$30\ per\ computer\ sold

b=\$475

If the blue radius below is perpendicular to the green chord and the segment BC is 7.6 units long, what is the length of the cho
galina1969 [7]

Answer:

The correct answer is A. 15.2 units

Step-by-step explanation:

The segment AB is congruent to the segment BC  eg AB≅BC Why?

We can prove it with the triangle congruent theorem, postulate side-side-angle

We are watching triangle ΔABO and triangle ΔCBO, they are congruent

first element side OB=OB - common side

second element side OA=OC=r - radius of the circle

third element angle ∡ABO≅∡CBO=90°

According to the postulate side-side-angle we can conclude that triangles

ΔABO≅ΔCBO (triangles are congruent)

If they are congruent all of their elements are also congruent and therefore also

side AB=BC  => AB+BC=AC,  which is chord  => 7.6+7.6=15.2 units

AC= 15.2 units ( chord )

Good luck!!!
