Answer:
Sin0 = 25/43
cot0 = 7/5
csc0 = 43/35
Step-by-step explanation:
X^2 = 5^2 + 7^2
X^2 = 25 +49
X^2 = 74
X = sqrt (74) = 8.6
Opp = 5
Adj = 7
Hypo = 8.6
sin0 = opp/Hypo = 5/8.6
Sin0 = 50/86 = 25/43
cot0 = 1/tan0 = adj/opp
cot0 = 7/5
csc0 = 1/cos0 = hypo/adj
csc0 = 8.6/7 = 86/70 = 43/35
Flour to sugar....u have 3 1/2 cups of flour and 1 1/4 cups of sugar (not sure if u mean brown or granulated...but either way, they are the same)...so ur ratio can be 3.5 cups to 1.25 cups.....or it can be 7/2 cups to 5/4 cups...depends on if u want it in decimals or fractions.
to compare the 2 quantities....um...3 1/2 cups flour > 1 1/4 cups sugar
======================
how many cups of flour do u need for each egg....
3 1/2 cups of flour.....and 2 eggs
(7/2) / 2 =
7/2 * 1/2 =
7/4 or 1 3/4.....so u need 1 3/4 cups of flour per egg <==
========================
I am having trouble reading ur rate table....but if 3 dozen (36 cookies) requires 2 teaspoons, then....
cookies : 6 12 18 24 30 36 180
vanilla : 1/3 2/3 1 1 1/3 1 2/3 2 10
the strategy used was a proportion : 36/2 = (number of cookies) / x...I just subbed in number of cookies and solved for x (number of teaspoons).
=======================
How many cookies do u need to sell to earn at least 60% of 120 ? and 40% of 120 ?
so if this relates to ur other question....then u r selling ur cookies at 1.60 for 4 cookies.....that means 1.60/4 = 0.40 per cookie
60% of 120 = 0.60(120) = 72
0.40x > = 72
x > = 72/0.40
x > = 180.....u would have to sell at least 180 cookies
40% of 120 = 0.40(120) = 48
0.40x > = 48
x > = 48 / 0.40
x > = 120....u would need to sell at least 120 cookies

Answer:
The population is the population of 3521 people who made credit card purchases.
The sample is the 172 people who returned the survey form.
Step-by-step explanation:
Department mails customers satisfactions forms to those who make credit cards purchase at the store, totaling 3521 people. Thus, the population is the population of 3521 people who made credit card purchases.
Surveys are mailed to 278 of these people, chosen at random, and 172 people return the survey form.
Thus the sample, that is, those from whom the data will be taken and expanded to the rest of the population, is the 172 people who returned the survey form.
