Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129

The weights of baskets of strawberries are normally distributed with a mean of 3.8 ounces and a standard deviation of 1.1 ounces. One grocery store advertises that the weight of their strawberries is in the 97.5th percentile. How many ounces do their strawberries weigh?
A 3.8 ounces
B 4.9 ounces
C 6 ounces
D 7.1 ounces
Answer:
6 ounces
Step-by-step explanation:
this one is mainly elimination. 3.8 and 4.9 cant be because they're too close to the mean. and 7.1 is too far. you can also use z-score. the z score of .975 is 1.96 we can plug that into out formula so
1.96=(x-3.8)/1.1
multiply both sides by 1.1 and then add 3.8
you can also use scientific calculator.
second vars, 3, the area is your percent so .975, the u is mean so 3.8, the o is standard deviation so 1.1

determine the arc of length AB. Give your answer in TWO DECIMAL PLACES.
Answer:
19.47m
Step-by-step explanation:
Radians = π/180 * degree
0.0174 x 124 = 2.164 rad
Arc AB = Radius * Angle ( In Radians )
AB = 9 x 2.164
=> 19.47m

y = - x - 11/3
Amanda financed a new living room set at the furniture store for $2,700. The store offered no interest for 6 months or 20 percent annually if the balance was not paid in full prior to the end of the interest free period. How much interest will she need to pay if she lets the account go for 6 months and 1 day before paying the bill?
Answer:
She will need to pay $269.36 in interest if she lets the account go for 6 months and 1 day before paying the bill.
Step-by-step explanation:
Given that Amanda financed a new living room set at the furniture store for $ 2,700, and the store offered no interest for 6 months or 20 percent annually if the balance was not paid in full prior to the end of the interest free period, to determine how much interest will she need to pay if she lets the account go for 6 months and 1 day before paying the bill, the following calculation must be performed:
((2,700 x 0.2) / 365) x 182 = X
(540/365) x 182 = X
1.48 x 182 = X
269.36 = X
Therefore, she will need to pay $ 269.36 in interest if she lets the account go for 6 months and 1 day before paying the bill.

I’m taking a final that’s almost due 23. A clerk needs to price a cashmere sweater returned by a customer. The customer paid a total of $222.36 that included a gift wrapping charge of $4 and a 9% sales tax. What price should the clerk mark on the tag? A. $222.00 B. $200.33 C.$198.71 D.$ 200.00
Answer:
$200.33
Step-by-step explanation:
Total amount paid = $222.36
Wrapping charge = $4
Sales tax = 9%
The price would be:
Cost + sales tax amount = (Total amount paid - wrapping charge)
Cost + sales tax amount = (222.36 - 4)
Cost + sales tax = 218. 36
Subtracting the sales tax :
Let cost = x
x + 0.09x = 218. 36
1.09x = 218.36
x = 218.36 / 1.09
x = $200.33
