Every evening Jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she had 38 coins all of them dimes and quarters. When she added them up she had a total of $6.95
Answers
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Answer:
She had 17 dims and 21 quarters to make $6.95.
Step-by-step explanation:
Given : Every evening Jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she had 38 coins all of them dimes and quarters.
To find : When she added them up she had a total of $6.95?
Solution :
Let d be the dims and q be the quarters.
She had 38 coins.
i.e. [tex]d+q=38[/tex] ......(1)
The value of d is 0.10 and q is 0.25.
The total she had of $6.95
i.e. [tex]0.10d+0.25q=6.95[/tex] .......(2)
Solving (1) and (2),
Substitute d from (1) into (2)
[tex]0.10(38-q)+0.25q=6.95[/tex]
[tex]0.10\times 38-0.10q+0.25q=6.95[/tex]
[tex]3.8+0.15q=6.95[/tex]
[tex]0.15q=6.95-3.8[/tex]
[tex]0.15q=3.15[/tex]
[tex]q=\frac{3.15}{0.15}[/tex]
[tex]q=21[/tex]
Substitute in equation (1),
[tex]d+21=38[/tex]
[tex]d=38-21[/tex]
[tex]d=17[/tex]
Therefore, She had 17 dims and 21 quarters to make $6.95.

A student ID number is a letter of the alphabet followed by 2 digits. How many different IDs are possible if the digits can be repeated?
Answers
Final answer:
There are 2600 different possible student IDs when a student ID consists of one letter followed by two digits that can repeat, calculated as 26 possible letters multiplied by 10 possible digits for each of the two digit positions.
Explanation:
The question asks how many different student IDs are possible if an ID consists of a letter followed by two digits, with the digits being allowed to repeat. To calculate the possible combinations, we multiply the number of options for each component of the ID. There are 26 letters in the alphabet and 10 possible digits (0-9) for each of the two positions that follow the letter, allowing for repetition.
The calculation is therefore 26 letters × 10 digits × 10 digits = 2600 possible combinations. Each component is independent of the others, so this follows the fundamental principle of counting in combinatorics.

A large tank is filled to capacity with 600 gallons of pure water. brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 6 gal/min. the well-mixed solution is pumped out at the same rate. find the number a(t) of pounds of salt in the tank at time t.
Answers
[tex]\dfrac{\mathrm dA(t)}{\mathrm dt}=\dfrac{4\text{ lbs}}{1\text{ gal}}\dfrac{6\text{ gal}}{1\text{ min}}-\dfrac{A(t)\text{ lbs}}{600\text{ gal}}\dfrac{6\text{ gal}}{1\text{ min}}[/tex]
[tex]\dfrac{\mathrm dA}{\mathrm dt}=24\dfrac{\text{lb}}{\text{min}}-\dfrac{A(t)}{100}\dfrac{\text{lb}}{\text{min}}[/tex]
Let's drop the units for now. We have
[tex]\dfrac{\mathrm dA(t)}{\mathrm dt}+\dfrac{A(t)}{100}=24[/tex]
[tex]e^{t/100}\dfrac{\mathrm dA(t)}{\mathrm dt}+e^{t/100}\dfrac{A(t)}{100}=24e^{t/100}[/tex]
[tex]\dfrac{\mathrm d}{\mathrm dt}\left[e^{t/100}A(t)\right]=24e^{t/100}[/tex]
[tex]e^{t/100}A(t)=\displaystyle24\int e^{t/100}\,\mathrm dt[/tex]
[tex]e^{t/100}A(t)=2400e^{t/100}+C[/tex]
[tex]A(t)=2400+Ce^{-t/100}[/tex]
We're given that the water is pure at the start, so [tex]A(0)=0[/tex], giving
[tex]A(0)=0=2400+Ce^{-0/100}\implies C=-2400[/tex]
So the amount of salt in the tank (in lbs) at time [tex]t[/tex] is
[tex]A(t)=2400\left(1-e^{-t/100}\right)[/tex]
To find the amount of salt in the tank at a given time, one can use the equation a(t) = Q - Qe^(-rt). In this case, Q (the quantity of salt at a steady state) equals the pump rate multiplied by the salt concentration (24lb/min), and r (the rate of inflow and outflow of the solution) is the rate at which water is pumped out divided by the volume of the tank (1/100 per min). Substituting these values into the equation gives the salt content at any given time.
Explanation:The quantity of salt in the tank at any given time can be determined by the equation of the form a(t) = Q - Qe^(-rt), in which Q is the quantity of salt that would be in the tank at a steady state (i.e., if enough time had passed that the quantity of salt in the tank stopped changing), r is the rate of inflow and outflow of the solution, and t is the time at which you're trying to determine the number of pounds of salt in the tank.
In this case, Q = rate of inflow x concentration of the inflow, which is 6 gal/min x 4 lb/gal = 24 lb/min. This amount is reached after a sufficient amount of time has passed and the tank has reached a steady state.
The rate, r, is the rate at which the water is pumped out of the tank. In this situation, that's 6 gallons per minute. Since there are 600 gallons of water in the tank at the start, r = 6 gal/min ÷ 600 gallons = 1/100 min^-1.
Therefore, the number of pounds of salt in the tank at any time t is a(t) = Q - Qe^(-rt) = 24 lb/min - 24 lb/min * e^[-(1/100 min^-1)*t].

Quadrilateral ABCD is similar to quadrilateral EFGH the length of the three longest side in quadrilateral ABCD are 24 feet 16 feet and 12 feet long if the two shortest sides of quadrilateral EFGH feet long and 18 feet long how long is the fourth side on quadrilateral ABCD ?
Answers
solve for "x"
since we know the two smallest sides for EFGH are 9 and 18, 9 is the smallest of all, and 18 is the next small
thus, for the the quadrilateral ABCD, the smallest is "x" and the next small is given, is 12, since that's smaller than 16 or 24
When all sides of a quadrilateral are transformed, the resulting quadrilateral will be similar to the transformed quadrilateral. The fourth side of ABCD is 6 feet
We have the lengths of ABCD in descending order to be:
[tex]Side\ 1 = 24[/tex]
[tex]Side\ 2 = 16[/tex]
[tex]Side\ 3 = 12[/tex]
We have the lengths of EFGH in ascending order to be:
[tex]Side\ 4 = 9[/tex]
[tex]Side\ 3 = 18[/tex]
The missing side of ABCD is the fourth side, and it can be solved using the following equivalent ratios:
Side 4 : Side 3 of ABCD = Side 4: Side 3 of EFGH
Substitute the values of the known sides
[tex]Side\ 4 : 12 = 9 : 18[/tex]
Express as fraction
[tex]\frac{Side\ 4 }{ 12} = \frac{9}{ 18}[/tex]
Multiply both sides by 12
[tex]Side\ 4 = \frac{9}{ 18} \times 12[/tex]
[tex]Side\ 4 = \frac{1}{2} \times 12[/tex]
[tex]Side\ 4 = 6[/tex]
Hence, the fourth side of ABCD is 6 feet

starting at home, luis traveled uphill to the hardware store for 30 minutes st just 8mph. he then traveled back home along the same path downhill at a speed of 24 mph. what is his average speed for the entire trip from home to the hardware store and back?
Answers
The main formula we use is :
Distance traveled = average Speed * Time,
in short: D = S * T
2.
"luis traveled uphill to the hardware store for 30 minutes at speed 8mph."
we have the speed and the time = 30 min = 1/2 h
so we can find distance:
D=ST=8 (mi/h) * 1/2 (h) = 4 mi
3.
Now we have D, and the speed 24 mph, so we can find the time it takes Luis to travel back home:
D=S*T
T= D/S = 4 (mi) / 24 (mi/h) =1/6 h
4.
The total distance is D+D = 4 +4 = 8 (mi)
the total time is 1/2 +1/6 = 3/6 + 1/6 = 4/6 = 2/3 (h)
So we can find the average speed of the entire trip is:
S=8 / (2/3)= 8* (3/2)=4*3=12 (mph)
Answer : 12 mph

convert to polar form y=3x^2
Answers
The polar form for the given expression is sin(θ)=3r−3rsin²(θ)
To convert the equation y = 3x² into polar form, we substitute[tex]\( x = r\cos(\theta) \) and \( y = r\sin(\theta) \)[/tex], where R is the radius and theta is the angle.
[tex]So, \( y = 3x^2 \) becomes:\[ r\sin(\theta) = 3(r\cos(\theta))^2 \][/tex]
Now, we can simplify this equation:
[tex]\[ r\sin(\theta) = 3r^2\cos^2(\theta) \]\[ r\sin(\theta) = 3r^2\cos^2(\theta) \]\[ \frac{r\sin(\theta)}{r^2} = 3\cos^2(\theta) \]\[ \frac{\sin(\theta)}{r} = 3\cos^2(\theta) \]\[ \frac{\sin(\theta)}{r} = 3(1 - \sin^2(\theta)) \]\[ \frac{\sin(\theta)}{r} = 3 - 3\sin^2(\theta) \]\[ \sin(\theta) = 3r - 3r\sin^2(\theta) \][/tex]
This equation describes the curve in polar coordinates.
