A water tank holds 256 gallons but is leaking at the rate of 3 gallons per week. A second water tank holds 384 gallons and is leaking at a rate of 5 gallons per week.After how many weeks will the amount of water in the two tanks be the same.
Step-by-step explanation:
you have: one is leaking 3 gallons per week and holds 256 gallons; whereas, the other one is leaking 5 gallons per week and holds 384 gallons.
Set up both the equations....
In y=mx+b form--->>>
y=-3x+256
y=-5x+384
To figure out when they will be equal..set the equations equal to each other....(remember to isolate the variable)
-3x+256=-5x+384
-3x+256=-5x+384
-256 -256
-3x=-5x+128
-3x=-5x+128
+5x+5x
2x=128
x=64
After 64 weeks the amount of water in both tanks will be the same.
Thus, your answer.

Find another point in the pattern that passes through the points (0, 2) and (2, 16)
9514 1404 393
Answer:
(4, 30)
Step-by-step explanation:
The two points in the pattern that are given here differ by 2 in their x-value and by 14 in their y-value. Another point can be found by adding 2 more to x and 14 more to y:
(2, 16) +(2, 14) = (4, 30)
The point (4, 30) is another point in the pattern.

Answer:
44.2545
Step-by-step explanation:
you can find the third angle by taking 180-(90+55)=a
a=35
use law of sines
Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)
so, sin(a)/A=sin(b)/B
sin(35)/33=sin(55)/x
x=sin(55)/(sin(35)/33)
x=44.2545

Jackson School is doing a fundraiser selling magazine subscriptions. The magazine publisher will pay the school a starting bonus of $500 and then $4 for each subscription sold. At the end of the fundraiser, the school is paid a total of $1360. How many subscriptions did they sell?
Answer: 215 subscriptions
Step-by-step explanation:
First, remove the starting bonus of $500 to find out the amount that was acquired from subscription sales:
= 1,360 - 500
= $860
The school is paid $4 for every subscription and they made $860 from this. The total number of subscription was therefore:
= 860 / 4
= 215 subscriptions

Write a system of two linear equations in two variables that can be used to model the
situation. Then choose a method to solve the system. Show your work and check your
answer.
Answer:
Step-by-step explanation:
h+n=14, n=14-h
2h+3n=34, using n=14-h
2h+3(14-h)=34
2h+42-3h=34
-h+42=34
-h=-8
h=8, and since n=14-h
n=14-8=6 so
They bought 8 hotdogs and 6 nachos.
A tower is topped by a right circular cone with a diameter of 24 feet and a height of 36 feet. The space inside the cone is used for housing electronic equipment.
361
Answer:
the answer is (5426)
Step-by-step explanation:
i got the answer online
The space inside the cone is 5426 cubic feet
What is the volume of a cone?
The formula for the volume of a cone is V = ( 1 / 3 ) πr²h.
Given data ,
Diameter of cone = 24 ft
Radius of cone = ( Diameter of cone / 2 ) = 12 ft
Height of cone = 36 ft
Space inside the cone = Volume of cone
Volume of Cone = ( 1 / 3 ) πr²h
= ( 1 / 3 ) x ( 22 / 7 ) x 12 x 12 x 36
= ( 22 / 7 ) x 48 x 36
= ( 22 / 7 ) x 1728
≈ 5426 cubic feet
Hence , the space inside the cone is 5426 cubic feet

Step-by-step explanation:
if a - b = 4 and a² - b² =12, what is the value of a + b?.
help.
Answer:
a² - b² = ± 32
Step-by-step explanation:
⇒ a + b = 4
⇒ a = 4 - b ... ( 1 )
Substituting this in another equation we get,
⇒ ab = -12
⇒ ( 4 - b ) ( b ) = -12
⇒ 4b - b² = -12
⇒ b² - 4b - 12 = 0
⇒ b² - 6b + 2b - 12 = 0
⇒ b ( b - 6 ) + 2 ( b - 6 ) = 0
⇒ ( b + 2 ) ( b - 6 ) = 0
⇒ b = -2, 6
Case 1: If b = -2
⇒ a = 4 - b
⇒ 4 - ( -2 ) = 4 + 2 = 6
Case 2: If b = 6
⇒ a = 4 - b = 4 - 6 = -2
Hence the numbers are 6 and -2.
⇒ a² - b² = ?
Case 1: a = 6 and b = -2
⇒ ( 6 )² - ( -2 )²
⇒ 36 - 4 = 32
Case 2: a = -2, b = 6
⇒ ( -2 )² - ( 6 )²
⇒ 4 - 36 = -32
Hence the answer for a² - b² can be ± 32 depending on the values of a and b.
