Answer:f = 57 g = 33
Step-by-step explanation:
Add f and g together and make them equal 90 and then solve for x and plug x back in to both angles 57 and 33
Answer:
m<F + m<G + m<H=180°[Sum of angles of traingle is Supplementary]
or,90°+(4x +13)°+(2x +11)°=180°
or,6x + 24°=180°-90°
or,6x=90°-24°
or,X=66°/6
:.X=11°
Now,
m<F=(4x+13)°=(4×11+13)°=57°
m<G=(2x+11)=(2×11+11)°=33°

No, Eric will not have enough banana bread to serve all 20 guests if he bakes only 3 loaves.
Eric is making banana bread to serve 20 guests, and he wants each guest to have 1/6 of a loaf. This means that each loaf will be divided into 6 equal portions, and each guest will receive one of these portions.
Eric plans to bake 3 loaves of banana bread. As 1 loaf can serve 6 guests with 3 loaves he can serve a total of
3×6 = 18 < 20
So only 18 guests can be served with 3 loaves of bread.

What are substitution reactions How are they classified give one example of each?
A substitution reaction is a reaction in which one group of molecules gets replaced by another group of molecules in an aqueous medium.
The substitution reactions are classified into three groups,
nucleophilic substitution electrophilic substitution homolytic substitution.In the nucleophilic reactions the atom is said to be rich in electron , whereas, in the electrophilic reaction, the atom is known to be an electron-deficient species.
The primary difference between substitution and elimination reactions is that substitution reactions replace one group with another, whereas elimination reactions merely remove the group. The main distinction between the groups is the number of stages involved in the reaction.
Example , R-Br + OH− → R-OH + Br−

What are complex numbers?Complex numbers are numbers that are composed by a real part and by an imaginary part, and have the notation given as follows:
z = a + bi.
In which:
a is the real part.b is the imaginary part.The most important complex numbers relation is given as follows:
i² = -1.
Meaning that the easiest way to obtain the desired product is multiplying complex-conjugate numbers, as follows:

A two-dimensional (2D) coordinate system is a system used to define the position of points in a two-dimensional plane.
What is 2D coordinates system?A 2D coordinate system can also be used to represent other kinds of data, such as temperature, elevation, or pressure. In this case, the two coordinates are usually called the x-axis and y-axis, and they are both used to measure the same physical quantity.
It is most commonly used in mathematics and engineering to plot graphical data such as graphs, charts, and diagrams. In a 2D coordinate system, each point is represented by two numbers, called coordinates, which indicate the position of the point in relation to a fixed reference point, called the origin. These coordinates usually describe the horizontal (x) and vertical (y) distances between the point and the origin. The set of all points in the 2D coordinate system is called the coordinate plane.

a. Write an inequality that demonstrates this situation
b. solve your inequality
c. Explain what your answer means to Tyrone
Answer:
a. Write an inequality that demonstrates this situation
Let x be the number of $5 t-shirts Tyrone can buy
The inequality that demonstrates this situation is:
x*5 + 22 <= 95 - 15
b. solve your inequality
x5 + 22 <= 80
x5 <= 58
x <= 11.6
x <= 11
c. Explain what your answer means to Tyrone
Tyrone has $95 to spend, he already bought pants for $22, so he has $95-22 = $73 left to spend. He wants to have at least $15 left over after buying t-shirts, so he can buy up to $73-15 = $58 worth of t-shirts. Each t-shirt costs $5, so he can buy a maximum of 11 t-shirts (58/5=11.6) with no remainder. So Tyrone can buy 11 t-shirts and he will have $73-11*5 = $18 left. This means that Tyrone can buy 11 t-shirts and still have $18 left over.

The antithesis of an exponential function is a logarithmic function. A logarithmic function and an exponential function both use the same base.
What is logarithm function?Writing y = log2 x or f(x) = log2 x represents the logarithmic function for the equation x = 2y. Even today, the base is still 2. Y equals log base b of x, or more simply, "y equals log to the base b of x," is how y = logb x is typically read. Similarly to exponential functions, b > 0 and b 1.
Consequently, the table's data is represented by the logarithmic function f(x) = log3(x).

Jee's trip from New York to Boston would take approximately time 4.5 hours.
To calculate the time it would take Jee to travel from New York to Boston, we need to divide the total distance (approximately 280 miles) by the average speed (42 mph). This gives us a total time of 6.67 hours. We then need to subtract the time it took Jee to travel from Boston to New York (6 hours) to get the total time for the return trip. 6.67 hours - 6 hours = 4.5 hours. Therefore, Jee's trip from New York to Boston takes approximately time 4.5 hours. Jee's trip from New York to Boston would take approximately 4.5 hours.

Answer: the total spent on the meal is $88.25875.
Step-by-step explanation:
The total spent on the meal can be calculated by adding the cost of the meal, the tax, and the tip.
First, we need to calculate the cost of the tax: 72.5 x 0.0675 = 4.88375
Then we need to calculate the cost of the tip: 72.5 x 0.15 = 10.875
Finally, we add the cost of the meal (72.5), the tax (4.88375) and the tip (10.875) to find the total cost of the meal: 72.5 + 4.88375 + 10.875 = 88.25875
Therefore, the total spent on the meal is $88.25875.

Solve the inequality for x.
-8+2x>4
By solving the given inequality in question, i.e -8+2x>4 , the solution obtained is x>6, which means the inequality satisfies for all the values of x that are greater than 6.
What is inequality?An inequality is a statement that compares two values and asserts that one value is greater than, less than, or not equal to the other value. Inequalities are used to describe a range of values that a variable can take on. The most common symbols used to express inequalities are ">", "<", "≥" and "≤", which represent "greater than", "less than", "greater than or equal to" and "less than or equal to" respectively.
Give an example of inequality?An example for inequality can be , the inequality x > 2 , which states that x is greater than 2, which means that any value of x that is greater than 2 satisfies the inequality.
Inequality can be solved either graphically or algebraically. The solution of an inequality is the set of all values that make the inequality true.
To solve the inequality -8 + 2x > 4, you can follow these steps:
Add 8 to both sides of the inequality: -8 + 2x > 4 becomes 2x > 12Divide both sides of the inequality by 2 : 2x > 12 becomes x > 6So the solution of the inequality is x > 6.
This means that x is greater than 6. So any value of x that is greater than 6 satisfies the inequality.

According to the given Question:
Differential equation:
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, a function generally represents a physical quantity, a derivative its rate of change, and a differential equation defines the relationship between the two. Such relationships are common. Therefore, differential equations play an important role in many fields such as engineering, physics, economics and biology.
The study of differential equations consists primarily of studying their solutions (the set of functions that satisfy each equation) and the properties of those solutions. Only the simplest differential equations can be solved with explicit formulas. However, many properties of solutions to particular differential equations can be determined without exact computation. In many cases, when a closed formula for the solution is not available, the solution can be approximated numerically using a computer. Although the theory of dynamical systems focuses on qualitative analysis of systems described by differential equations, many numerical methods have been developed to determine solutions with some degree of accuracy.
A first-order linear differential equation is an equation that can be written in the form y0 + p(x)y = q(x). where p and q are continuous functions on the interval I. The second-order linear differential equation has a similar form.
