No it does not form a proportion.
Proportion = equal
3 * 8 = 24
4 * 8 = 32 not 18
28.333333333. If you do a proportion and place it 1/(?) times .6/(17) you should multiply 17 by 1 (17*1) which should equal 17. You now have to divide it so 17 divided by .6 (17/6) which equals to 28.333333.
Answer:
B: If Mo pays cash, the cost of the purchase will be $140.
E: If Mo uses the credit card and pays off the balance at $20 a month for 7 months with no late fees, the cost of the purchase will be $139.89.
F: If Mo uses the credit card and pays the full balance during the billing cycle, the cost of the purchase will be $135.80.
Step-by-step explanation:
Answer: 90°
Step-by-step explanation:
scs(t)=1/sint
sint²+cost²=1
cot t=(cost/sint)²
(cost²/sint²)/Sint²=1/sint-sint
cost²/sint⁴=1/sint-sint
cost²=sint³-sint⁵
Cost²=sint³(1-sint²)
cost²=sint³cost²
1=sint³
sint=1
arcsin1=90°
Cot^2(t)=(cost/sint)²
