Marcon harvested more pomelos than Lope, by 199.25 kilos.
To calculate this, we need to subtract the amount harvested by Lope from the amount harvested by Marcon.
First, we need to convert the amounts into the same unit of measure. Both amounts are in kilos, so no conversion is needed.
Next, we can subtract the amount harvested by Lope from the amount harvested by Marcon: 362.75 kilos - 163.5 kilos = 199.25 kilos.
This means that Marcon harvested 199.25 kilos more pomelos than Lope.

Aliza needs to run at a rate faster than 8.2 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below:
He concludes that she is not running fast enough to exceed her fastest time.
What errors did the coach make?
The coach made a mistake in converting the average rate from miles per hour to feet per second. To convert miles per hour to feet per second, the formula is (miles per hour) x (5280 feet/mile) / (60 minutes/hour) = (feet per second).
However, the coach used a different conversion factor, which resulted in an incorrect value. This incorrect value led the coach to conclude that Aliza was not running fast enough, when in reality, the actual rate could be higher than 8.2 feet per second.
Therefore, the coach made an error in the conversion factor used and in the conclusion based on the incorrect converted value.
A' certain state legislature has senators and representatives. The combined number of senators and representatives is 290. The difference of the numbers is 180. There are more representatives than senators.
How many senators and how many representatives are in this state's legislature?
There are 55 senators and 235 representatives are in this state's legislature.
What do you mean by equation?An equation is a mathematical statement that shows the equality of two expressions. Equations can be used to represent relationships between variables and to solve problems. They are written using an equal sign (=) and can include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.
For example, the equation 2x + 3 = 7 is an equation that states that the expression on the left side (2x + 3) is equal to the expression on the right side (7). The goal is to find the value of the variable x that satisfies the equation. In this case, x = 2 is a solution to the equation.
Let's call the number of senators in the state legislature "s" and the number of representatives "r". We know the following:
s + r = 290 (the combined number of senators and representatives is 290)
r - s = 180 (the difference of the numbers is 180)
We can use the first equation to solve for one of the variables in terms of the other:
r = 290 - s
Next, we can substitute this expression for r into the second equation:
290 - s - s = 180
Simplifying the left-hand side:
290 - 2s = 180
Adding 2s to both sides:
290 = 180 + 2s
Subtracting 180 from both sides:
110 = 2s
Dividing both sides by 2:
s = 55
So there are 55 senators in the state legislature. To find the number of representatives, we can use the first equation:
r = 290 - s = 290 - 55 = 235
So there are 235 representatives in the state legislature.

Evaluate ∫∫D^y^dA where d is the set of points (x,y) such that 0 ≤ 2x/ π ≤ y, y ≤ sinx.
The value of the double integral is [tex]$-\frac{\pi}{12}$[/tex].
We are given that;
∫∫D^y^dA where d is the set of points (x, y)
0 ≤ 2x/ π ≤ y, y ≤ sin x
Now,
We can see that x varies from 0 to [tex]\pi[/tex], and for each fixed x, y varies from [tex]\frac{2x}{\pi} to \sin x[/tex]. Therefore, we can write the double integral as:
[tex]$$\iint_D y \, dA = \int_0^\pi \int_{\frac{2x}{\pi}}^{\sin x} y \, dy \, dx$$[/tex]
Now we can evaluate the inner integral with respect to y:
[tex]$$\int_{\frac{2x}{\pi}}^{\sin x} y \, dy = \frac{y^2}{2} \bigg|_{\frac{2x}{\pi}}^{\sin x} = \frac{\sin^2 x}{2} - \frac{2x^2}{\pi^2}$$[/tex]
Plugging this result into the outer integral, we get:
[tex]$$\iint_D y \, dA = \int_0^\pi \left( \frac{\sin^2 x}{2} - \frac{2x^2}{\pi^2} \right) dx = \frac{1}{4} \int_0^\pi (1 - \cos 2x) dx - \frac{2}{\pi^2} \int_0^\pi x^2 dx$$[/tex]
Using the antiderivatives of [tex]\cos 2x[/tex] and x^2, we get:

Find The Area Of The Region Under The Given Curve From 1 To 2. Y = 3 X3 + 4x
The area under the curve y = 3x³ + 4x from x = 1 to x = 2 is 4 square units.
What do you mean by curve?A curve is a continuous, smooth, and often repeating shape in the plane or in space. It is a geometric object that can be described mathematically by an equation or a set of points.
In mathematics, curves are used to model real-world phenomena and to study geometric and mathematical properties. For example, curves can be used to describe the shape of objects, the path of moving objects, or the graph of a mathematical function.
There are many types of curves, including lines, circles, ellipses, parabolas, hyperbolas, and spirals, among others. Each type of curve has unique properties and characteristics, and they are studied and used in different ways in different fields of mathematics and science.
In physics, curves are used to describe the motion of objects and the behavior of physical systems. For example, the trajectory of a projectile can be modeled by a parabolic curve, while the path of a planet around the sun can be modeled by an elliptical curve.
To find the area under the curve y = 3x^3 + 4x from x = 1 to x = 2, we can use the definite integral:
∫[1,2] (3x^3 + 4x) dx
To evaluate this integral, we can use the power rule for integration: ∫x^n dx = (x^(n+1))/(n+1) + C, where C is the constant of integration.
Using this rule, we get:
∫ (3x³ + 4x) dx = ∫ 3x³ dx + ∫ 4x dx = x^4/4 + 2x² + C
Evaluating this definite integral from x = 1 to x = 2, we get:
[tex][x^{\frac{4}{4}+2x^{2} } ]2-[x^{\frac{4}{4}+2x^{2} } ]1=(2^{\frac{4}{4} }+22^{2} ) -(1^{\frac{4}{4} } +21^{2} )=\frac{21}{4}-\frac{16}{4}=4[/tex]

initial investment of $7,000 and when you choose to invest for 14 years you get a 10% rate
of return. What will be the value of your investment at maturity?
y = a (1 + r)t
Round off to the nearest whole number
(don't forget to change your rate to a decimal percentage)
Rounding off to the nearest whole number, the value of the investment at maturity would be $15,108.
What is the whole number?
A whole number is a positive integer that has no fractional or decimal component. Whole numbers include 0, 1, 2, 3, 4, and so on.
The formula to calculate the future value of an investment is given by: y = a (1 + r)t, where y is the future value, a is the initial investment, r is the rate of return as a decimal, and t is the time in years.
In this case, the initial investment is $7,000, the rate of return is 10% (or 0.10 as a decimal), and the time in years is 14. So, the calculation would be:
y = $7,000 * (1 + 0.10)^14
y = $7,000 * 1.10^14
y = $7,000 * 2.151373

Answer:
Below
Step-by-step explanation:
See diagram below solve the angles in order 1-2-3-4-5-6
as shown in the diagram:
Answer:
85 degrees
Step-by-step explanation:
Okay, let's have a look at the triangle on the left.
We can see an exterior angle of 115 degrees, adjacent to the interior angle.
Thus, as they both form a line (180 degrees), Interior angle = 180 - 115
= 65 degrees
We know that all the angles of the triangle equal 180.
Now to find the remaining angle of the triangle on the left,
180 - (85 + 65) = 30 degrees
Moving towards the center, we have our interior triangle angle (30 degree), a 90 degree angle and an interior angle of the triangle on the right. So, as they all form a line, the interior angle of the triangle on the right will be
180 - (90 + 30) = 60 degrees
Also, on top of the triangle on the right, we have a 115 degree exterior angle again.
Repeating our first step, the interior angle would be 65 degree
Now to find the remaining angle of the triangle on the right,
180 - (30 + 65) = 95 degrees
This angle forms a line with another angle exterior to this one, so again,
180 - 95 = 85 degrees

Ahmed ell boxe of pen ($8) and rubber band ($4). Leona ordered a total of 30 carton for $220. How many boxe of pen did Leona order?
By applying the algebra concept, it can be concluded that Leona ordered 25 boxes of pens.
Algebra is a branch of mathematics that uses symbols and mathematical operations, such as addition, subtraction, multiplication, and division to solve problems.
We have this information:
The price of a box of pens = $8
The price of a box of rubber bands = $4
Total order = 30 boxes
Total payment = $220
Let p symbolize the number of pens and r symbolize the number of rubber bands. Now we have the following equations:
p + r = 30 ....................... (1)
8p + 4r = 220 ............... (2)
To find the value of p and r, we can do it by simplifying the first equation as follows:
p + r = 30
r = 30 - p
Then we can substitute this value into the second equation:
8p + 4r = 220
8p + 4(30 - p) = 220
8p + 120 - 4p = 220
4p = 220 - 120
= 100
p = 100/4
= 25 boxes of pens
So we can calculate the value of r as well:
r = 30 - p
= 30 - 25
= 5 boxes of rubber bands
Thus, it can be concluded that Leona ordered 25 boxes of pens.
