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.
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.
An observatory is shaped like a cylinder standing on one of its bases with a dome on top. The diameter of the floor of the observatory is 64 feet, as shown in the diagram. What is the measurement of the circumference of the base of the observatory in feet to the nearest hundredths place?
Answer:
201.14 ft
Step-by-step explanation:
C = 2 π r = π d
C = [tex]\frac{22}{7}[/tex] × 64 ≈ 201.14 ft
Answer:
3215.36
Step-by-step explanation:
C=πr²
C=3.14(32)²
C=3.14(32·32)
C=3.14(1024)
C=3215.36

Susanna found a roll of fabric she wanted to use to make a pillow. The roll had of a yard of fabric left. Susanna needed of the remaining fabric. Which fraction represents how much fabric Susanna needed?
Answer:
1/4 of a yard
Step-by-step explanation:
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
You buy 1 box of dog food and 2 cans of cat food for $25. Your friend buys 2 boxes of dog food and 1 can of cat food for $26.
The cost of 1 box of dog food is $ 9 and cost of 1 can of cat food is $ 8
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 1 box of dog food be = x
Let the cost of 1 can of cat food be = y
The cost of 1 box of dog food and 2 cans of cat food = $ 25
The cost of 2 boxes of dog food and 1 can of cat food = $ 26
So , the equation will be
1x + 2y = 25 be equation (1)
2x + 1y = 26 be equation (2)
Now , Multiply equation (1) by 2 , we get
2x + 4y = 50 be equation (3)
On Subtracting equation (2) from equation (3) , we get
3y = 24
Divide by 3 on both sides , we get
y = $ 8
Substituting the value of y in equation (1) , we get
x + 2 ( 8 ) = 25
x + 16 = 25
Subtracting 16 on both sides , we get
x = $ 9
Therefore , the value of x is $ 9 and value of y is $ 8
Hence , the cost of 1 box of dog food is $ 9 and the cost of 1 can of cat food is $ 8

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?
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

Please help quick for 25 points with explanations. Any silly and absurd answers will be reported.
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.

Sam put 3000 into saving it earned 6% simple interest annually after 6 years how much will Sam have
Answer:
the future value is 4,080
Step-by-step explanation:
The computation of the future value under the simple interest is shown below:
As we know that
Future value = Present value × (1 + rate of interest × time period)
= 3,000 × (1 + 6 × 6%)
= 3,000 × (1 + 0.36)
= 3,000 × 1.36
= 4,080
Hence, the future value is 4,080

Find the measure of angle KMJ
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
Estimate a 20% tip on a dinner bill of $131.58 by first rounding the bill amount to the nearest ten dollars.
