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

Step-by-step explanation:
-5x-10+5x-25
Answer:
-5x-10+5x-25
x-10=-25
x=-15
Step-by-step explanation:
you distribute both 5s into the problem. one side will be negative 5x minus 2 becomes 10 because negative times a positive is a negative. you're multiply negative 5 times 2 bring down the plus sign. the second part is positive 5x minus 5 which becomes 5x minus 25. you multiply positive 5 times 5 to get that answer for the second part. you combine like terms. positive 5x and negative 5x cancels out to become x-10=-25. add 10 on both sides and x=-15
This is trigonometry btw
Answer: x = 13.3
Step-by-step explanation:
Use SOHCAHTOA
The opposite of the angle and the adjacent of the angle is given, so use tangent.
tan(35) = x/19
19*tan(35) = x
x = 13.3
90 / 811 = 58 / x
Answer the porportion
Answer:
x = 522.64
Step-by-step explanation:
cross-multiply:
90x = 811(58)
90x = 47,038
x = 47038 / 90
x = 522.64
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

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.

Answer:
combined means to add so you are going to add anything over 1 because it says longer than 1
1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =
they have like denominators so you can add them together
1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2
so your answer is 2 1/2

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.

Hope that this is helpful. Tap the crown button, Mark my answer as............. BRAINLIST......... Like & Follow me to get more answer.
Answer:
x = 3.6, y = 0.4
Step-by-step explanation:
make x the subject in equation 1:
x = 4 - y (equation 3)
substitute equation 3 into equation 2:
2(4-y) - 3y = 6
8 - 2y - 3y = 6
8 - 6 = 5y
2 = 5y
y = 2/5
y = 0.4
substitute (y=0.4) into equation 3:
x = 4 - 0.4
x = 3.6

9514 1404 393
Explanation:
If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.
Example:
A = 0.56 ⇒ C = 0.6
B = 0.66 ⇒ D = 0.7
__
B - A = 0.66 -0.56 = 0.10
D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.

// divide both sides by 3
x + 1 < 6
x < 6 - 1
x < 5

Mrs. Neville is baking five batches of cookies. She will need 2 \frac{1}{2} 2 1 cups of flour for each batch of cookies. If she begins with a 20 cup bag of flour, what is the resulting change in the amount of flour in the bag?
Answer:
12.5 cups used
7.5 cups left
Step-by-step explanation:
Number of batches = 5
Cups of flour per batch = 2 1/2 cups
Initial amount of flour = 20 cup bag
After 5 batches ; number of cup used :
5 * 2 1/2 = 12.5 cups of flour
Change in amount of flour in bag :
(20 cups - 12.5 cups) = 7.5 cups
