Answer:
66 coolers
Step-by-step explanation:
C = 0.005x² - 0.3x + 17
When C = $19
19 = 0.005x² - 0.3x + 17
19 - 17 = 0.005x² - 0.3x
2 = 0.005x² - 0.3x
0.005x² - 0.3x - 2 = 0
x = -b ± √b² - 4ac / 2a
= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005
= 0.3 ± √ 0.09 - (-0.04) / 0.01
= 0.3 ± √ 0.09 + 0.04 / 0.01
= 0.3 ± √ 0.13 / 0.01
= 0.3/0.01 ± √0.13/0.01
= 30 ± 0.36/0.01
x = 30 ± 36
x = 30 + 36 or 30 - 36
x = 66 or -6
Number of coolers can not be negative
Therefore, number of coolers produced when the cost is $19
is 66 coolers

Gym a charges $25 per month plus a $60 initiation fee. Gym b charges $30 per month and no initiation fee. Find the number of months it will take for the total cost for both gyms to be equal
Answer:
12 months
Step-by-step explanation:
Given data
Gym A
charges $25 per month plus a $60 initiation fee
let the number of months be x
and the total charges be y
y= 60+25x---------------1
Gym B
charges $30 per month and no initiation fee
let the number of months be x
and the total charges be y
y=30x---------------2
Equate 1 and 2 above to find x
60+25x= 30x
collect like terms
60= 30x-25x
60= 5x
divide both sides by 5
x= 60/5
x= 12
Hence it will take 12 months

Complete Question
William has $7.50 to spend at the pretzel shop. A large pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and p pretzels. Which inequality can be used to find the number of pretzels William can buy?
a) 1.25p−0.9≤7.5
b) 1.25p+0.9≤7.5
c) 1.25p+0.9≥7.5
d) 1.25+0.9p≤7.5
Answer:
b) 1.25p+0.9≤7.5
Step-by-step explanation:
William has $7.50 to spend at the pretzel shop.
This means Williams can spend at least $7.50
A pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and ?pretzel
Therefore, the inequality can be used to find the number of pretzels William can buy is written as
1.25p+0.9≤7.5

If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current
Answer:
1.9 Amps
Step-by-step explanation:
In an RC circuit, the relationship between the current I in amps, the impedance Z in ohms and the voltage V in volts may be stated as
V = IZ
As such, given that z = 52.5 ohms and V = 100 Volts, the current in the circuit I may be computed as
100 = I * 52.5
Divide both sides by 52.5
I = 100/52.5
= 1.9 Amps

What is the percent equation for 46% of 127?
Answer:
46% of 127 is 58.42
Step-by-step explanation:
46/100 = x/127
Cross multiply
46 × 127 = 100 × x
5,842 = 100x
Divide both sides by 100
58.42 = x
It is actually 2m/s2
Answer:

Step-by-step explanation:
Solve the equation
x-4=-x+2
Answer:x=3
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Given
x-4=-x+2
Add x on both sides
x-4+x=-x+2+x
2x-4=2
Add 4 on both sides
2x-4+4=2+4
2x=6
Divide 2 on both sides
2x/2=6/2
x=3

(4,−4), (k,−1); m=3/4 i need to know what k is
Answer:
8
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
3/4=(-1-(-4))/(k-4)
3/4=(-1+4)/(k-4)
3/4=3/(k-4)
cross product
4*3=3(k-4)
12=3(k-4)
12/3=k-4
4=k-4
k=4+4

A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
Answer:
251.33in²
Step-by-step explanation:
A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
We solve the above question using the formula for Total surface area of a cylinder.
TSA = 2πr (h + r) Square units.
Where
h = Height of the cylinder
r = Radius of the cylinder
Diameter of the container is 10 inches
Hence, radius = Diameter/2 = 10/2 = 5 inches
Height is 3 inches.
Hence, Total surface area =
2 × π × 5 (5 + 3)
= 10π × (8)
= 251.32741229 in²
Approximately = 251.33 in²
Therefore, the amount of sand that can fit into the cylinder = 251.33 in²
