<h3>Answer:  12 (choice D)</h3>

=========================================

Work Shown:

Angle DCA = 15 degrees (given in diagram)

Angle BAC = 15 degrees, since BAC and DCA are alternate interior angles, so they are congruent to one another. This works because AB is parallel to CD.

Ignore point D. Focus on triangle BAC only. Two angles are known: A = 15, B = 153. Solve for angle C

A+B+C = 180

15+153+C = 180

C+168 = 180

C = 180-168

C = 12

For triangle ABC (ignore point D) the angle C is 12 degrees. If D is involved in the diagram, angle BCA is 12 degrees.

Step-by-step explanation:

Multiply 12600 by -3/4 to determine the amount earned.

*12600 can be put over 1.

<u>Multiply:</u>

\frac{12600}{1}  \times  \frac{ - 3}{4}  =  \frac{37800}{4}

<u>Simplify by dividing the fraction by 4:</u>

\frac{ - 37800 \div 4}{4 \div 4}  =  \frac{ - 9450}{1}

If 1 square food of grass seed = 25cents ,then how much would grass seed cost for 55,000 square feet of grass seed
vagabundo [1.1K]
Okay. So 25 cents is expressed as 0.25. it is $0.25 for a square foot of grass seed. To find the cost for 55,000 square feet of grass seed, all you have to do is multiply the cost per square foot by the amount of square feet total. In this case, we would multiply 55,000 by 0.25. 55,000 * 0.25 is 13,750. There. The total cost would be $13,750.

PLEASE HELP ME IM IN A BIG HURRY
Alex787 [66]
Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00

Part B:
Total price: $24.99 + $2.00 = $26.99
