PLZ I NEED HELP WITH THIS QUIZ PLZ SHOW WORK WILL MARK BRAINLIEST

1: No, the ratios are not proportional because if you multiply 16/9 to get a common denominator, your two fractions are 84 / 54 and 96/54, which are not equal.

2: $1.70. You need to find the unit rate, by dividing 4.76 by 7. Once you do, you'll get $0.68 per pound. Then, multiply by the number of pounds you have, which in this case is 2.5. 0.68 * 2.5 = $1.70.

3. No, the relationship is not proportional. The first ratio is 6/4, which is not equivalent to 10/8. With a common denominator, 6/4 = 12/8, which is not equal to 10/8.

4. Option B. You need to find the unit rate of dollars per oz by dividing 3.29/20, which equals 0.1645. 4.49/32 = 0.1403 is less than 0.1645, so Option B is the better deal.

5. 2/5. There are four vowels to ten consonants. 4/10 simplified is 2/5.

Good luck!

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

idk this answer sorry cant on this one.
