Answer: AB 90 IB 150 IC 135 AC 90

Step-by-step explanation:

All triangles have to equal 180, if B is 60 and I is 90, 60+90=150, 180-150=30 then A=30 if a equals 30 than 60+30=90 A+B=AB (same with the others.)

The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight

Galina-37 [17]

The weight of the full steel bead tire in pounds is 1.76 pounds

The weight of the lighter steel bead tire in pounds is 1.54 pounds.

<h3>What are the weights of the tires?</h3>

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

The weight of the full steel bead tire in pounds = 800 / 453.592 = 1.76

The weight of the lighter steel bead tire in pounds = 700 / 453.592 = 1.54

The polynomial 2x3 − 5x2 + 4x − 10 is split into two groups, 2x3 + 4x and −5x2 − 10. The GCFs of each group is then factored out

Ugo [173]

$Answer: \\ 2 {x}^{3} - 5 {x}^{2} + 4x - 10 \\ = (2 {x}^{3} + 4x) - (5 {x}^{2} + 10) \\ = 2x( {x}^{2} + 2) - 5( {x}^{2} + 2) \\ = ( {x}^{2} + 2)(2x - 5) \\ Common \: binomial \: factor:2x - 5$
