The sum of -1 7/8 and 1 11/12
Answer:
1/24
Step-by-step explanation:
Step-by-step explanation:
-1 7/8+1 11/12
=-15/8+23/12 by taking Lcm as 24 we get:
=-45+46/24=1/24
When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n +1/5 n = 24. What is the value n? n = 18 n = 20 n = 214/5 n = 234/5
For this case we must find the value of n of the following equation:
[tex]n + \frac {1} {5} n = 24[/tex]
Taking common factor "n" from the left side of the equation we have:
[tex]n (1+ \frac {1} {5}) = 24\\n \frac {6} {5} = 24[/tex]
Multiplying by 5 on both sides of the equation:
[tex]6n = 120[/tex]
Dividing between 6 on both sides of the equation:
[tex]n = 20[/tex]
Thus, the value of n is 20.
Answer:
[tex]n = 20[/tex]
Answer: Second Option
[tex]n = 20[/tex]
Step-by-step explanation:
Let's call n the number searched.
Then one fifth of this number is written as
[tex]\frac{1}{5}n[/tex]
Then at 1 / 5n the number n is added.
So, we have
[tex]n + \frac{1}{5}n[/tex]
Now we know that the result of this sum is equal to 24. Then we write the equation:
[tex]n + \frac{1}{5}n = 24[/tex].
Now we solve the equation:
[tex]\frac{6}{5}n = 24[/tex]
Muple both sides of equality by [tex]\frac{5}{6}[/tex]
[tex]\frac{5}{6} * \frac{6}{5}n = 24*\frac{5}{6}[/tex]
[tex]n = 20[/tex]

Find the x-intercepts of the parabola with
vertex (-3,-14) and y-intercept (0,13).
Write your answer in this form: (X1,Y1), (X2,42).
If necessary, round to the nearest hundredth.
The x-intercepts of the parabola are [tex]\(x = -3 + \sqrt{\frac{14}{3}}\) and \(x = -3 - \sqrt{\frac{14}{3}}\).[/tex]
To find the x-intercepts of the parabola, we need to set y=0 in the equation of the parabola and solve for x.
Given that the vertex of the parabola is [tex]\((-3, -14)\),[/tex] the equation of the parabola can be expressed in the form [tex]\(y = a(x - h)^2 + k\)[/tex], where [tex]\((h, k)\)[/tex]represents the vertex and a is the coefficient determining the direction and width of the parabola.
Using the vertex form, we have:
[tex]\[ y = a(x + 3)^2 - 14 \][/tex]
We know that the y-intercept is (0,13) so when x=0, y=13:
[tex]\[ 13 = a(0 + 3)^2 - 14 \]\[ 13 = a(9) - 14 \]\[ 13 = 9a - 14 \]\[ 9a = 13 + 14 \][/tex]
[tex]\[ 9a = 27 \]\[ a = \frac{27}{9} \]\[ a = 3 \][/tex]
So, the equation of the parabola is:
[tex]\[ y = 3(x + 3)^2 - 14 \][/tex]
Now, to find the x-intercepts, we set y=0:
[tex]\[ 0 = 3(x + 3)^2 - 14 \]\[ 3(x + 3)^2 = 14 \]\[ (x + 3)^2 = \frac{14}{3} \][/tex]
Now, we take the square root of both sides:
[tex]\[ x + 3 = \pm \sqrt{\frac{14}{3}} \][/tex]
Ramon invested $2,400 into two accounts. One account paid 3% interest and the other paid 6% interest. He earned 5% interest on the total investment. How much money did he put in each account?
Answer:
In the account that paid 3% Ramon put [tex]\$800[/tex]
In the account that paid 6% Ramon put [tex]\$1,600[/tex]
Step-by-step explanation:
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
[tex]P(rt)=Pa(rat)+Pb(rbt)[/tex]
in this problem we have
[tex]t=t\ years\\ P=\$2,400\\ Pa=\$x\\ Pb=\$(2,400-x)\\r=0.05\\ra=0.03\\rb=0.06[/tex]
substitute
[tex]2,400(0.05t)=x(0.03t)+(2,400-x)(0.06t)[/tex]
solver for x
Simplify
[tex]2,400(0.05)=x(0.03)+(2,400-x)(0.06)[/tex]
[tex]120=0.03x+144-0.06x[/tex]
[tex]0.03x=24[/tex]
[tex]x=\$800[/tex]
therefore
In the account that paid 3% Ramon put [tex]\$800[/tex]
In the account that paid 6% Ramon put [tex]\$2,400-\$800=\$1,600[/tex]
To solve this problem, we set up an equation representing the total interest earned from the two different bank accounts. After doing a bit of algebra, we find that Ramon put $1200 into each account.
Explanation:This question falls into the category of the linear system in mathematics which deals with simple interest calculations. The total amount invested by Ramon is $2400 and we don't know how it was distributed into the two accounts, so we can name the amount in the account with 3% interest x and the other with the 6% interest 2400-x, as the total should be $2400.
We know the total interest earned was 5% of the whole sum, so we can set up the equation:
0.03x + 0.06(2400 - x) = 2400 * 0.05.
Solving the equation, we find that x, the amount in the first account, is $1200 and therefore, $1200 must have been put into the second account.

Giuseppi's Pizza had orders for $931.00 of pizzas. The prices were $21 for a large pizza, 514 for a medium pizza, and $7 for a small pizza. The number of large pizzas was two less than four times the number of medium pizzas. The
number of small pizzas was three more than three times the number of medium pizzas. How many of each size of pizza were ordered?
Answer:
Number of Large Pizzas: 30
Number of Medium Pizzas: 8
Number of Small Pizzas: 27
Step-by-step explanation:
L = # of large Pizzas
M = # of medium Pizzas
S = # of small Pizzas
Amount:
L = 4M - 2
S = 3M + 3
Cost:
21L + (I'm assuming you meant 14) 14M + 7S = 931
Plus in the Amounts to the Cost:
21(4M - 2) + 14M + 7(3M + 3) = 931
84M - 42 + 14M + 21M +21 = 931
Combine like terms:
119M - 21 = 931
Isolate the Variable:
119M - 21 + 21 = 931 + 21
119M = 952
119M/119 = 952/119
M = 8
Plug it into the Amount equations:
Large: L = 4(8) - 2
L = 32 - 2
L = 30
Small: S = 3M + 3
S = 3(8) + 3
S = 24 + 3
S = 27
Check your work (plug the values into Cost.):
21(30) + 14(8) + 7(27) = 931
630 + 112 + 189 = 931
931 = 931
The number of medium pizzas ordered was 10. Hence, based on the given relationships, the number of large pizzas was 38 and the number of small pizzas was 33.
Explanation:To solve this problem, really, we are using three algebraic expressions that represent the total cost, the relationship between the large and medium pizzas, and the relationship between the small and medium pizzas.
We can define M as the number of medium pizzas, L as the number of large pizzas, and S as the number of small pizzas. We can then set up the following equations based on the problem:
$21L + $14M + $7S = $931L = 4M - 2S = 3M + 3We can substitute equations 2 and 3 into equation 1 to get a single equation in terms of M:
$21(4M-2) + $14M + $7(3M+3) = $931
Which simplifies to:
93M = 931
Then, M=10, hence, the number of medium pizzas is 10, number of large pizzas (4M-2) is 38, and the number of small pizzas (3M+3) is 33.

Rewrite the equation in standard form using integers.
Answer:
4x - 3y -18 = 0 or y = 4x/3 - 6
Step-by-step explanation:
We will have to find the slope of the line first
The formula for slope:
[tex]m =\frac{y_{2}- y_{1} }{x_{2} -x_{1} } \\m= \frac{-2-2}{3-6}\\ =\frac{-4}{-3}\\ =\frac{4}{3}[/tex]
The standard form of equation of a line is:

Substitute: (x=0,y=-3)
[tex] - 3 = a {(0)}^{2} + b(0) + c[/tex]
[tex] \implies \: c = - 3...(1)[/tex]
Substitute: (x=-1,y=-11) and c=-3
[tex] - 11 = a {( - 1)}^{2} + b( - 1) + - 3[/tex]
[tex] \implies \: - 11 = a - b - 3[/tex]
[tex] \implies \: a - b = - 8...(2)[/tex]
Substitute: (x=3,y=-27) and c=-3
[tex] -27= a {( 3)}^{2} + b( 3) + - 3[/tex]

Final answer:
To fit a quadratic function to the three given points, we use the general form y = ax² + bx + c and set up a system of equations. Solving the system yields the function y = -2x² + 6x - 3.
Explanation:
To fit a quadratic function to the points (-1, -11), (0, -3), and (3, -27), we need to find a function of the form y = ax² + bx + c where a, b, and c are constants. We will set up three equations based on the given points:
-11 = a(-1)² + b(-1) + c-3 = a(0)² + b(0) + c-27 = a(3)² + b(3) + cSolving these equations gives us a system:
a - b + c = -11c = -39a + 3b + c = -27From the second equation, we have c = -3. Inserting that into the first and third equations:
a - b = -89a + 3b = -24Solving this system gives us a = -2 and b = 6.
Therefore, the quadratic function fitting the points is y = -2x² + 6x - 3.

a snake slithers 2/9 miles in 4/5 hours what is its speed in miles per hour
Answer:
5/18
Step-by-step explanation:
speed = distance / time
s = (2/9 miles) / (4/5 hours)
To divide by a fraction, multiply by the reciprocal:
s = (2/9) × (5/4)
s = 10/36
s = 5/18
So the snake's speed is 5/18 miles per hour.
Final answer:
To calculate the snake's speed, you divide the distance (2/9 miles) by the time (4/5 hours), resulting in a speed of 5/18 miles per hour.
Explanation:
To calculate the snake's speed in miles per hour, we divide the distance traveled by the time taken. The snake slithers 2/9 miles in 4/5 hours, which can be written as a rate equation:
Speed = Distance ÷ Time
Plugging in the numbers, we calculate:
Speed = (2/9) miles ÷ (4/5) hours
To find the speed in miles per hour, we solve the equation:
Speed = (2/9) ÷ (4/5)
To divide one fraction by another, we multiply by the reciprocal of the divisor:
Speed = (2/9) × (5/4)
Speed = (2×5) ÷ (9×4)
Speed = 10/36
When this fraction is simplified, it equals 5/18 miles per hour.
If we want to relate it to units of m/s as the reference information suggests, we can use an online unit converter or unit analysis, considering that 1 mile per hour is approximately equal to 0.44704 meters per second.

In physics, Ohm's law says that current through a wire, I, is directly proportional to voltage, V, and inversely proportional to resistance, R:
I=V/R.
It's also true that resistance is directly proportional to the length of the wire. We have a piece of wire. We pass 12 volts through this wire and measure 100 milliamps of current. If I cut the wire in half and pass 24 volts through it, how many milliamps of current will I measure?
If you cut the wire in half and pass 24 volts through it, you would measure 400 milliamps of current.
Ohm's law states that the current (I) through a wire is directly proportional to the voltage (V) and inversely proportional to the resistance (R). The formula is given by:
[tex]\[ I = \frac{V}{R} \][/tex]
If you double the voltage (V) and cut the wire in half, the length of the wire (which affects resistance) is also halved. Let's denote the original resistance as [tex]\( R_1 \)[/tex] and the halved resistance as [tex]\( R_2 \)[/tex]. The new equation becomes:
[tex]\[ I_2 = \frac{V_2}{R_2} \][/tex]
Now, since resistance is directly proportional to the length of the wire, we can write:
[tex]\[ R_2 = \frac{1}{2} \cdot R_1 \][/tex]
Substitute this into the previous equation:
[tex]\[ I_2 = \frac{V_2}{\frac{1}{2} \cdot R_1} \][/tex]
Now, let's use the information given. Initially, [tex]\( V_1 = 12 \)[/tex] volts and [tex]\( I_1 = 100 \)[/tex] milliamps. We can find [tex]\( R_1 \)[/tex] using Ohm's law:
[tex]\[ R_1 = \frac{V_1}{I_1} \][/tex]
Substitute the values:
[tex]\[ R_1 = \frac{12 \, \text{volts}}{100 \, \text{milliamps}} = 120 \, \text{ohms} \][/tex]
Now, substitute [tex]\( R_1 \)[/tex] into the equation for [tex]\( I_2 \)[/tex]:
[tex]\[ I_2 = \frac{24 \, \text{volts}}{\frac{1}{2} \cdot 120 \, \text{ohms}} \][/tex]
Simplify:
[tex]\[ I_2 = \frac{24 \, \text{volts}}{60 \, \text{ohms}} \][/tex]
[tex]\[ I_2 = 0.4 \, \text{amps} \][/tex]
To convert amps to milliamps, multiply by 1000:
[tex]\[ I_2 = 0.4 \, \text{amps} \times 1000 = 400 \, \text{milliamps} \][/tex]
Therefore, if you cut the wire in half and pass 24 volts through it, you would measure 400 milliamps of current.
By applying Ohm's law, the new current measured after cutting the wire in half and applying 24 volts is calculated to be 400 milliamps.
Explanation:According to Ohm's law, the current (I) through a resistor is directly proportional to the voltage (V) and inversely proportional to the resistance (R), as described by the equation I = V / R. Given the initial conditions of 12 volts and 100 milliamps of current, we can calculate the resistance of the wire using R = V / I. The resistance (R) would then be 120 ohms.
When the wire is cut in half, the resistance is halved because resistance is directly proportional to the length of the wire. Now, with a resistance of 60 ohms and applying 24 volts across it, the new current can be calculated with Ohm's law by I = V / R, which gives us I = 24 V / 60 Ω = 0.4 A, or 400 milliamps of current.
Anyone know the answer?
Answer:
A 4955.30
Step-by-step explanation:
A = P ( 1+i) ^ t
where A is the amount in the account
P is the principal
i is the interest rate
and t is the time in years
A = 4000(1+.055)^4
A = 4000(1.055)^4
A = 4955.2986025
Rounding to the nearest cent
A = 4955.30

The area of parking lot is 1710 square meters. A car requires 5 square meters and a bus requires 32 square meters of space. There can be at most 189 vehicles parked at one time. Of the cost to park a car is $2.00 and a bus is $6.00, how many buses should be in the lot to maximize income?
Answer:
To maximize the income should be 28 buses and 160 cars
Step-by-step explanation:
Let
x-----> the number of cars
y ----> the number of bus
we know that
[tex]5x+32y\leq1,710[/tex] ------> inequality A
[tex]x+y\leq 189[/tex] ----> inequality B
The function of the cost to maximize is equal to
[tex]C=2x+6y[/tex]
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
The vertices of the solution are
(0,0),(0,53),(160,28),(189,0)
Verify
(0,53)
[tex]C=2(0)+6(53)=\$318[/tex]
(160,28)
[tex]C=2(160)+6(28)=\$488[/tex]
therefore
To maximize the income should be 28 buses and 160 cars
Answer:
There should be 30 buses in the lot to max out income
