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!

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
