Answer:
$61.44
Step-by-step explanation:
Both the tip and the tax are based on the original amount ($48).
To find the amounts, first change the percents to decimals.
8% = 0.08
20% = 0.20
Then, multiply the decimals by the original amount.
48 × 0.08 = 3.84
48 × 0.20 = 9.60
Next, add up the original amount, the tax, and the tip to find the total money spent by Lucy.
$48 + $3.84 + $9.60 = $61.44
The total amount spent is $61.44.
Lucy pay total amount of $61.44, including tax and the tip.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Both the tip and the tax are based on the original amount ($48).
To determine the amounts, first change the percents to decimals.
8% = 0.08
20% = 0.20
Now multiply the decimals by the original amount.
48 × 0.08 = 3.84
48 × 0.20 = 9.60
Next, add up the original amount, the tax, and the tip;
$48 + $3.84 + $9.60 = $61.44
The total amount spent will be $61.44.

Olivia is a stockbroker. She makes 4% of her sales in commission. Last week, she sold $7,200 worth of stocks.
a. How much commission did she make last week?
b. If she were to average the same commission each week, how much would she make in commission in a year, treating a year as having exactly 52 weeks.
Answer:
i think a is 6912:)
i thin b is 359424:)
Step-by-step explanation:
i'm so sorry if it's wrong <3
The answers for the given problem are as (a) the commission made by Olivia in a week is $288 and (b) the total commission for a year is $14976.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price of stocks sold = $7200.
The commission percentage = 4%.
(a) The commission made by Olivia per week is found as,
4% of 7200
= 4/100 × 7200
= 288
(b) Considering 52 weeks in a year, the commission made by her in a week is given as,
52 × 288
= 14976
Hence, the commision made by her in a week is $288 and the total commission for a year is $14976.

PLEASE HELP Solve for x.
52
(3x+8)
Answer:
x = 10
Step-by-step explanation:
1. (3x + 8) and (52) are both complementary angles, which means that they add up to 90 degrees. Therefore, we can set up an equation of: \((3x+8) + 52 = 90\)
2. (Solving)
Step 1: Simplify both sides of the equation.
\((3x+8) + 52 = 90\) \(3x + (8+52) = 90\) \(3x + 60 = 90\)Step 2: Subtract 60 from both sides.
\(3x + 60 - 60 = 90 - 60\) \(3x = 30\)Step 3: Divide both sides by 3.
\(\frac{3x}{3} = \frac{30}{3}\) \(x = 10\)Therefore, x = 10.

You can purchase 10 songs on Apple Music for $7.50. Which graph represents this proportional situation
The graph that represents this proportional situation would be a straight line with a slope of 0.75 (7.5/10) that passes through the point (10, 7.5).
What is a proportional relationship on a graph?You should consider the ratios between the two variables to determine whether a relationship is proportional. A proportionate relationship exists when the ratio remains constant. The relationship will no longer be proportionate if the ratio changes.
The ratio of the y-coordinate to the x-coordinate must be determined for a specific point on the graph in order to determine the constant of proportionality.
The graph that represents this proportional situation would be a straight line with a slope of 0.75 (7.5/10) that passes through the point (10, 7.5). This line represents the relationship between the number of songs and the cost. For every 10 songs purchased, the cost would be $7.50.

question 9 of 10 explain how you can determine the sign of the sum of two integers if one integer is positive and the other integer is negative.
To determine the sign of the sum of two integers when one integer is positive and the other is negative, we can follow a simple rule based on their magnitudes.
If the magnitude of the positive integer is greater than the magnitude of the negative integer, the sum will be positive. This is because the positive integer outweighs the negative integer, resulting in a positive value.
On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.
In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.
By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

A spherical surface encloses three charges q=4q, q= 5q, q, q=-7q. A fourth charge q= -5q is placed outside the sphere. How much is the flux of the electrical field through the spherical surface worth? let c the dielectric constant of vacuum
The flux of the electric field through the spherical surface is zero.
The flux of the electric field through a closed surface is given by the Gauss's law, which states that the flux is equal to the total charge enclosed divided by the dielectric constant of vacuum (ε₀).
In this case, the spherical surface encloses charges of magnitude 4q, 5q, q, and -7q, but the net charge enclosed is zero since the charges cancel each other out. Therefore, the flux through the spherical surface is zero in this case.

The equation of the line in point-slope form and in slope-intercept form are both y = 1/2x.
There are three common forms of the equation of a line:1. Point-Slope Form: y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line.
2. Slope-Intercept Form: y = mx + b, where m is the slope of the line and b is the y-intercept.
3. Standard Form: Ax + By = C, where A and B are coefficients that define the slope and y-intercept of the line.
If a line has a slope of 1/2 and passing through the origin, then:
m = 1/2
(x1, y1) = (0,0)
Plug in the values in the point-slope form and in slope-intercept form.

y(t) = Ce^(2t) is indeed a solution to the given differential equation\(y'(t) - 2y(t) = 0.\)
To verify that the given function y(t) = Ce^(2t) is a solution of the differential equation y'(t) - 2y(t) = 0, we'll first find y'(t) and then substitute y(t) and y'(t) into the differential equation.
1. Find the derivative of y(t) with respect to t:
\(y'(t) = d(Ce^(2t))/dt = 2Ce^(2t)\)
2. Substitute y(t) and y'(t) into the differential equation:
y'(t) - 2y(t) = 0
\(2Ce^(2t) - 2(Ce^(2t)) = 0\)
As we can see, the equation holds true, and thus, \(y(t) = Ce^(2t)\) is indeed a solution to the given differential equation \(y'(t) - 2y(t) = 0.\)

find an upper bound on the error that can result if cos(x) is approximated by 1−(x2/2!) (x4/4!) over the interval [−0.7,0.7].
An upper bound on the error that can result from approximating cos(x) by 1−(x^2/2!) + (x^4/4!) over the interval [-0.7, 0.7] is 0.00567.
The Taylor series expansion for cos(x) is given by cos(x) = 1 - (x^2/2!) + (x^4/4!) - (x^6/6!) + ... . The approximation 1−(x^2/2!) + (x^4/4!) is a truncated version of this series. The error between the actual value of cos(x) and the approximation can be estimated using the Lagrange form of the remainder term, which gives an upper bound on the error.
In this case, the Lagrange remainder term is given by Rn(x) = (f^(n+1)(c)/n+1!) * (x-x0)^(n+1), where f^(n+1)(c) is the (n+1)th derivative of cos(x) evaluated at some point c in the interval [-0.7, 0.7].
The maximum value of Rn(x) over the interval [-0.7, 0.7] occurs when x = ±0.7, and the upper bound on the error is found by evaluating Rn(±0.7).
The resulting upper bound is approximately 0.00567.
