Target is having a huge winter season sale on all of their televisions. A 42in screen tv that usually retails at $580 is marked down by 20%. If you brought $450 to the store, do you have enough money to buy the tv? Explain your reasoning.

Answers

Answer: You do not because the tv costs $464.

Step-by-step explanation:

First find out how much 20% of 580 is:

= 20% * 580

= $116

The television was therefore marked down by $116. The current selling price is:

= 580 - 116

= $464

Since you came with $450, you will not be able to buy the television as you would be short of the $464 required.

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 17,897 gallons of water, and is leaking at a rate of 5 gallons per day. If Mike does not replace the water that has leaked from the pool, how many gallons of water will remain in the pool after 187 days?

Answers

Answer:

Gallons of water remaining = 16,962 gallons

Step-by-step explanation:

Total capacity of the pool = 17,897 gallons

Rate of leakage per day = 5 gallons

Number of days = 187 days

how many gallons of water will remain in the pool after 187 days?

Gallons of water remaining = Total capacity of the pool - (Rate of leakage per day × Number of days

= 17,897 - (5 × 187)

= 17,897 - 935

= 16,962 gallons

Gallons of water remaining = 16,962 gallons

Find the measure of angle KMJ

Answers

Answer:

54 Degrees

Step-by-step explanation:

We know that the interior angles of a triangle add up to 180 degrees.

we also know that angle KLM = 48 degrees

and angle JKM = 78 degrees

since these triangles are on parallel lines we know that their angles must be equal (just inverted)

and thus:

180 - (48+78) = 54

Answer:

Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±[tex]\sqrt{61}[/tex])/2. So, PQ=[tex]\frac{\sqrt{61} }{2}[/tex], PQ²=[tex]\frac{61}{4}[/tex]. Thus, the answer is 61+4=65.

Susanna found a roll of fabric she want to use to make a pillow. The roll had 3/4 of a yard of fabric left. Suzanne need 1/3 of the remaining fabric. Which fraction represents how much fabric Susanna needed?

Yard of fabric left = 3/4 of a yard

Yards needed by Susanna = 1/3 of the remaining fabrics

= 1/3 of 3/4 of a yard

= 1/3 × 3/4

= 1/4 of a yard

Therefore Susanna needs 1/4 of a yard of fabrics

The fraction which represents how much fabric Susanna needed is 1/4 of a yard
