If he makes no other deposits or withdrawals, how much money is in Javier’s account at the end of three months?
Enter your answer in the box.
282.50
if his bank charges him $7.50 each month for a balance below of $500
then Javier who did not deposit or withdraw (added or subtracted) but had a total of 305 would be charged 7.50 for those 3 months
305 - 7.50 (3) = X
305 - (22.5)
282.50
Answer: He had $277.50 at the end of 3 months.
Step-by-step explanation:
Since we have given that
Amount he had in his bank account = $305
Bank charges each month = $7.50
Number of months = 3
So, Bank charges for 3 months would be
[tex]7.50\times 3\\\\=\$22.5[/tex]
So, Amount left in his bank account would be
[tex]\$305-\$22.5\\\\=\$277.50[/tex]
Hence, he had $277.50 at the end of 3 months.

A jug holds 4.8 liters. How many milliliters does it hold? Enter your answer in the box.
Answer:
The jug will hold 4,800 milliliters.
Step-by-step explanation:
Each liter is 1000 milliliters, and 4.8 • 100 = 4,800
The jug holds 4800 milliliters. The conversion factor is that 1 liter is equal to 1000 milliliters.
Explanation:The subject of this question is based on the concept of volume conversion, specifically from liters to milliliters. This falls within the field of Mathematics. In the metric system, volume can be measured in cubic meters (m³), liters (L), and milliliters (mL). These units of volume are used in different scenarios depending on the magnitude of the volume to be measured. One liter (L) is equal to 1 cubic decimeter (dm³), or 1,000 cubic centimeters (cm³).
One common metric conversion is from liters to milliliters. This is because 1 Liter equals 1000 milliliters.
Therefore, if a jug holds 4.8 liters, we can find the equivalent volume in milliliters by multiplying the volume in liters by 1000. In this case, 4.8 liters * 1000 equals 4800 milliliters

What interest rate per annum is a fund paying its clients if the third to the last payment of a depositor became Php 1,040.40 from an initial savings payment of Php 1,000.00?
Answer: The rate of interest per annum is 1.3%.
Step-by-step explanation:
Given Principal P= $1000
time period n=3
Amount A=$1040,40
To find rate of interest per annum r
We know that
[tex]A=P(1+\frac{r}{100} )^3\\\Rightarrow\ 1040=1000(1+\frac{r}{100})^3\\\Rightarrow\ 1.040=(1+\frac{r}{100})^3\\\text{taking log on both sides}\\log(1.040)=3log(1+\frac{r}{100})\\\Rightarrow0.039=3log(1+\frac{r}{100})\\\Rightarrow0.013=log(1+\frac{r}{100})\\\\\Rightarrow\ e^{0.013}=(1+\frac{r}{100})\\\Rightarrow\ 1.013=(1+\frac{r}{100})\\\Rightarrow\ \frac{r}{100}=1.013-1=0.013\\[/tex]

The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p). If the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds, what is the volume under a pressure of 30 pounds?
a) 45 cubic cm b) 20 cubic cm c) 12.8 cubic cm
Answer : C) 12.8 cubic cm
The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p)
If y is inversely proportional to x then [tex]y=\frac{k}{x}[/tex]
where k is constant of proportionality
v is inversely proportional to p then [tex]v=\frac{k}{p}[/tex]
the volume of a gas is 24 cubic centimeters when the pressure is 16 pounds
Given : v= 24 and p = 16. We need to find out k
[tex]24=\frac{k}{16}[/tex]
Multiply by 16 on both sides
k = 384
Now we find out the volume under a pressure of 30 pounds
[tex]v=\frac{384}{30}[/tex]
[tex]v=\frac{128}{10}[/tex]= 12.8 cubic cm
Under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters, as determined by applying Boyle's law, which states that volume and pressure are inversely proportional in conditions of constant temperature.
The volume (v) of a gas in a container at a constant temperature varies inversely as the pressure (p). This is a demonstration of Boyle's law, which states that pressure and volume are inversely proportional (P = k/V) when temperature is held constant. To find the new volume when the pressure changes, we can set up a proportion based on the original conditions provided: 24 cm³ at 16 pounds pressure. We set the initial volume and pressure as 24 cm³ and 16 lbs, respectively, and then solve for the new volume when the pressure is 30 lbs.
To find the volume under a pressure of 30 pounds, we use the equation:
V1 * P1 = V2 * P2
Where V1 is the original volume, P1 the original pressure, V2 the new volume, and P2 the new pressure. Plugging in our known values:
24 cm³ * 16 lbs = V2 * 30 lbs
Solving for V2, we get:
V2 = (24 cm³ * 16 lbs) / 30 lbs
V2 = 384 cm³ / 30 lbs
V2 = 12.8 cm³
Therefore, under a pressure of 30 pounds, the gas would occupy a volume of 12.8 cubic centimeters.
a paper coffee filter has a radius of 6 centimeters and a slant of height of 12 centimeters. find the surface area of the filter. round your answer to the nearest whole number.
Final answer:
The surface area of the paper coffee filter with a radius of 6 centimeters and a slant height of 12 centimeters is approximately 339 square centimeters when rounded to the nearest whole number.
Explanation:
Finding the Surface Area of a Coffee Filter
To find the surface area of the paper coffee filter, we need to consider it as a part of a cone because a coffee filter is shaped like a cone with a circular base. The surface area of a cone is calculated by the formula Surface Area = πr(r + l), where r is the radius and l is the slant height. Given that the radius of the coffee filter is 6 centimeters and the slant height is 12 centimeters, the formula should be filled in as follows:
Radius (r) = 6 cm
Slant Height (l) = 12 cm
The calculation will then be:
Surface Area = π x 6 cm x (6 cm + 12 cm)
Surface Area = π x 6 cm x 18 cm
Surface Area = π x 108 cm²
Surface Area ≈ 3.14159 x 108 cm²
Surface Area ≈ 339.29 cm²
Rounding to the nearest whole number:
Surface Area ≈ 339 cm²
The surface area of the paper coffee filter is approximately 339 square centimeters.

6. Solve: A chemist needs 30 ounces of 50% hydrochloric acid solution. In her lab, she has some 80% hydrochloric acid solution, some 60% hydrochloric acid solution, and some 40% hydrochloric acid solution. She must use 2 ounces of the 80% solution. How many ounces each of the 40% and 60% solutions must be mixed with the 2 ounces of 80% to obtain the 30 ounces of 50% hydrochloric acid solution she needs?
Final answer:
To prepare 30 ounces of a 50% hydrochloric acid solution, the chemist must mix 17 ounces of the 40% solution with 11 ounces of the 60% solution and 2 ounces of the 80% solution.
Explanation:
The student needs to mix different concentrations of hydrochloric acid to end up with 30 ounces of a 50% solution. We know that 2 ounces of the 80% solution are used, so the remaining 28 ounces must be a mix of the 40% and 60% solutions.
Let x represent the ounces of the 40% solution and 30 - 2 - x, or 28 - x, represent the ounces of the 60% solution. Setting up the equation based on mass of pure hydrochloric acid:
0.80(2) + 0.40(x) + 0.60(28 - x) = 0.50(30)Solving for x:
1.6 + 0.40x + 16.8 - 0.60x = 15-0.20x + 18.4 = 15-0.20x = -3.4x = 17The chemist needs to use 17 ounces of the 40% solution and 11 ounces of the 60% solution, combining them with the 2 ounces of the 80% solution to obtain 30 ounces of 50% hydrochloric acid.
A total of 336 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
A total of 336 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold then the number of adult tickets sold = 112
Let's denote the number of adult tickets sold as 'A' and the number of student tickets sold as 'S'.
We are given two pieces of information:
1. The total number of tickets sold is 336: A + S = 336.
2. The number of student tickets sold was two times the number of adult tickets sold: S = 2A.
Now, we can use the second equation to substitute the value of 'S' in terms of 'A' into the first equation:
A + 2A = 336.
Combine the like terms:
3A = 336.
Now, isolate 'A' by dividing both sides by 3:
A = 336 / 3.
A = 112.
So, the number of adult tickets sold (A) is 112.
In summary, to find the number of adult tickets sold, we set up equations based on the given information and then solve for the variable representing the number of adult tickets (A).
By substituting the value of 'A' back into one of the equations, we can also find the number of student tickets sold (S).
In this case, 112 adult tickets and 224 student tickets were sold to make a total of 336 tickets.

Nolan deposited $2300 into a savings account for which interest is compound weekly at a rate of 2.12%.
How much interest will he earn after 7 years?
Answer:
The answers is 367.87
Step-by-step explanation:
The interest Nolan will earn after 7 years of time lapse, with the given figures, is $4,863,465 approx.
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that simple interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
For the considered case, the unit of time is weekly.
In 7 years, there can be at least 1 leap year, and at max 2 leap years.
In 7 years, therefore, the number of days are between [tex]6 \times 365 + 366[/tex] and [tex]6 \times 365 + 366+1[/tex] or say in between 2556 and 2557
Since each week has 7 days, therefore, the number of weeks these days will have is approx [tex]\dfrac{2556}{7} \approx 365.14[/tex] (assumed there are 2556 days in 7 years).
This approximates to 365 weeks (integer quantity)
Thus, we get:
Unit of time is weekRate of interest per week = 2.12%Type of interest applied = Compound interestUnits of week for which interest is applied is approx 365Initial amount deposited = $2300Thus, the amount of interest that Nolan will earn is approx:
[tex]CI = P(1 +\dfrac{R}{100})^T - P\\\\CI \approx 2300(1 + 0.0212)^{365} - 2300 \approx 2300 \times 2115.65 - 2300\\CI \approx \$4,863,465[/tex]
Thus. the interest Nolan will earn after 7 years of time lapse, with the given figures, is $4,863,465 approx.
