A hat at the store is being offered at a 15% discount. If the original price of the hat is x, which answer choice shows an expression that represents the discounted price of the hat?

Answers

.85x is the discounted price of the hat

The discounted price of the hat is 0.85x.

What is discounted price?

Discount is the difference between the marked price (list price) and the selling price of an article. Therefore, the formula used for discount calculation is: Discount = List price - selling price.

Given that, a hat is at 15% discount price, we need to find the expression that represents the discounted price of the hat,

The discount = x - SP

15% of x = x - SP

SP = 85% of x

SP = 0.85x

Hence, the discounted price of the hat is 0.85x.

The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
A. 264
B. 462
C. 528
D. 536

Answers

Answer: C. 528

Explication: 88x2 weeks= 176 so 88x6weeks=528
First, there were 88 blooms in one week, now they are asking how many flowers will there be after 6 weeks, so you take 88 multiply by 6 (88x6) which gives you 528...so technically you will get C.528

In the figure, j∥k and m∠2 = 117°. What is the m∠3? Enter your answer in the box. ° Line t diagonally crossing parallel lines j and k (reading from top to bottom). Angles formed by t crossing j are labeled one through four, starting at top right and going counterclockwise, where angle one is acute. Angles formed by t crossing k are labeled five through eight, starting at top right and going counterclockwise.

Answers

Answer:

63 degrees

Step-by-step explanation:

Since the angles are going counter-clockwise, angle 2 and angle 3 are supplementary, meaning that they add up to 180 degrees.

Since angle 2 is 117 degrees, 180 - 117 = 63. Therefore, angle 3 is 63 degrees
