Samir and Kylie are making fruit salads for a picnic. Samir mixes 1 cup of melon and 3 cups of apple and Kylie mixes 2 cups of melon and 9 cups of apple. Use Samir and Kylie’s percent of melon to determine whose fruit salad will taste more melony.
Samir's fruit salad has a higher percentage of melon and will taste more melony than Kylie's fruit salad.
What is percentage?Percentage is a way of expressing a proportion or a fraction as a number out of 100. It is represented by the symbol % (percent).
In the given question,
To determine whose fruit salad will taste more melony, we need to calculate the percentage of melon in each fruit salad.
For Samir's fruit salad:
The total amount of fruit is 1 + 3 = 4 cups
The amount of melon is 1 cup
The percentage of melon is (1/4) x 100% = 25%
For Kylie's fruit salad:
The total amount of fruit is 2 + 9 = 11 cups
The amount of melon is 2 cups
The percentage of melon is (2/11) x 100% = 18.18% (rounded to two decimal places)
Therefore, Samir's fruit salad has a higher percentage of melon and will taste more melony than Kylie's fruit salad.

(x³ + kx² - 34x +56) ÷ (x + 7)
Answer:
Step-by-step explanation:
Because this problem is not easily solvable through factoring, we must use long division to find the answer.
_______________ x+7 | x3 + kx2 - 34x + 56
When performing long division on polynomials, we should try to cancel out the term with the greatest power first. So, we must figure out how many x's go into x3, because x is the first term of the first polynomial and x3 is the first term of the second polynomial. x*x2 = x3, so:
x2
_______________ x+7 | x3 + kx2 - 34x + 56
(-) x3 + 14x2
(k-14)x2 - 34x
Then, we see how many x's go into (k-14)x2. x*(k-14)x = (k-14)x2, so:
x2 + (k-14)x
_______________ x+7 | x3 + kx2 - 34x + 56
(-) x3 + 14x2
(k-14)x2 - 34x
(-) (k-14)x2 - 7kx - 98x
-7kx - 132x + 56= (-7k-132)x + 56
x*(-7k-132) = (-7k-132)x, so:
x2 + (k-14)x + (-7k-132)
_______________ x+7 | x3 + kx2 - 34x + 56
(-) x3 + 14x2
(k-14)x2 - 34x
(-) (k-14)x2 - 7kx - 98x
(-7k-132)x + 56
(-) (-7k-132)x - 7k - 924
-7k - 868
The answer is x2 + (k-14)x + (-7k-132) - [(7k-868)/(x+7)]

Work out the median.
Answer:
5.5
Step-by-step explanation:
The median is the middle number in an ordered ascending/descending list.
The first step is to order the list. In this case I chose to do so in ascending order.
This gets you:
2 3 3 4 5 6 6 6 7 9
In this case there is an even amount of numbers, which means there will be 2 central numbers, 5 and 6.
Averaging these two numbers will get you the median.
(5+6) / 2 = 5.5

The rate of change of the area outside the circle but inside the square is 1 m² per minute.
What is area?Area is the measure of the size of a two-dimensional (2D) shape or planar region. It is expressed in terms of square units, such as square metres (m2) and square feet (ft2). The area of a shape is the total space contained within its boundaries.
To answer this question, we need to find out the area outside the circle but inside the square. This can be done by subtracting the area of the circle from the area of the square.
The area of the circle is equal to πr², where r is the radius of the circle. In this case, the radius is 3 meters, so the area of the circle is π×32 = 28.27 m².
The rate of change of the area outside the circle but inside the square is 1 m²per minute.
The area of the square is equal to side², where side is the length of one side of the square. In this case, the side is 16 meters, so the area of the square is 162 = 256 m².
Subtracting the area of the circle from the area of the square gives us the area outside the circle but inside the square. This is 256 - 28.27 = 227.73 m².
Now, we know the area outside the circle but inside the square, and we know that the radius of the circle is increasing at a rate of 1 meter per minute and the sides of the square are increasing at a rate of 2 meters per minute. This means that the area outside the circle but inside the square is increasing at a rate of (2 - 1) = 1 m²per minute.
Therefore, the rate of change of the area outside the circle but inside the square is 1 m² per minute.

What is an equation for the linear relationship in slope-intercept form?
A. y=2x+3
B. y=12x+3
C. y=12x−3
D. y=−12x−3
A: y=2x+3. This is an equation for the linear relationship in slope-intercept form. The equation states that the value of y is equal to the slope of the line, 2, multiplied by the value of x, plus 3.
What is slope?Slope is a measure of the steepness of a line. It is the ratio between the vertical change in a line (change in y-values) over the horizontal change in the same line (change in x-values). It is also referred to as the rate of change, as it is a measure of how quickly the value of y changes with respect to the x-value.
This equation is used to describe a straight line that has a constant rate of change between two variables. This equation can be used to determine the slope, y-intercept, and x-intercept of a line.
The slope, which is the coefficient of x in the equation (2 in this case), is the rate at which y changes with respect to x. It is the rise over run, or the change in y over the change in x. The y-intercept is the value of y when x is equal to 0 (in this case, it is 3). The x-intercept is the value of x when y is equal to 0 (in this case, it is -3/2).
This equation is often used to represent a linear relationship between two variables, such as the amount of money a person earns in relation to the number of hours they work.

Find the volume of a cone with a radius of 4 ½ m. and a height of 10 m.
The volume of the cone is approximately 211.06 cubic meters.
Why is that?
Well, the formula for the volume of a cone is:
V = (1/3)πr^2h
where:
Substituting the given values, we get:V = (1/3)π(4.5m)^2(10m)
V = (1/3)π(20.25m^2)(10m)
V = (1/3)π(202.5m^3)
V = 67.5π
Using a calculator, we get:
V ≈ 211.06 cubic meters
Therefore, the volume of the cone is approximately 211.06 cubic meters.

A triangular bookshelf has a base of 10 inches and 18 inches will the bookshelf fit in the corner of a square living room
No, if fit indicates that the bookcase's sides must be flush with the wall, which means that they must touch the wall and that the bookshelf is correctly positioned in that location.
What are triangles?A triangle is a polygon with three edges and three vertices.
It belongs to the basic geometric shapes.
A triangle having vertices A, B, and C is known as triangle ABC.
Any three locations in Euclidean geometry that are not collinear result in a distinct triangle and a distinct plane.
I've discovered that using the 3:4:5 triangle is the simplest way to determine for sure if an angle is 90 degrees.
This rule states that a triangle is a right triangle even if one of its sides is 3 and the other is 4 if the diagonal connecting its two points measures 5.
So, we must check to see if any of the bookcase's vertices measure 90 degrees because a square room will naturally have corners that do.
We may utilize Pythagorean Theorem to find the solution because every right triangle contains a 90° angle.
Pythagorean The a, b, and c are the legs, and the theorem states that a² + b² = c².
For our bookshelf, 10 and 12 are the legs, and 18 would be the hypotenuse if it were a right triangle as the hypotenuse is always the longest side.
To determine whether the equation is true or false, enter the values.
10² + 12² = 18²
100 + 144 = 324
244 ≠ 324
Thus, the bookshelf does not form a straight angle and cannot be placed in the room's corner.
Therefore, no, if fit indicates that the bookcase's sides must be flush with the wall, which means that they must touch the wall and that the bookshelf is correctly positioned in that location.

Correct question:
A triangular bookshelf has a base of 10 inches,12 inches, and 18 inches. Will the bookshelf fit in the corner of a square living room?
Pls answer today and fast!!!! Use the tools below to make a triangle with angle measures or 60 degrees, 40 degrees, and 80 degrees.
An angle is a geometric figure formed by two rays or line segments that share a common endpoint, called the vertex. Angles are measured in degrees or radians and are typically denoted by symbol ∠ followed by the name of the vertex, like ∠ABC.
What is the Angle?The size of angle is determined by amount of rotation needed to bring one of rays or line segments into coincidence with others.
Angles can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), or reflex (greater than 180 degrees).
Angles are fundamental to geometry and have many applications in physics, engineering, and other fields.
This is because the sum of the angles in a triangle must always be 180°, and 40° + 60° + 80° = 180°.
However, the angles do not satisfy the conditions of the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, It is not possible to construct a triangle with angle measures of 40°, 60°, and 80°.

Can anyone solve the following two maths?
In conclusion the team took 50 strokes to complete the final 500 meters of the race and at the end of the season, the team's mean split time should be 99 seconds.
How to find?
To find the answer to question 37, we know that the team rowed the final 500 meters in 108 seconds. We also know that they rowed at a rate of 28 strokes per minute during this split. To find out how many strokes they took to complete the final 500 meters, we need to convert the split time to minutes and then multiply by the stroke rate.
First, we convert the split time to minutes:
108 seconds ÷ 60 seconds per minute = 1.8 minutes
Then, we multiply by the stroke rate to find the total number of strokes:
1.8 minutes x 28 strokes per minute ≈ 50 strokes
Therefore, to the nearest whole number, the team took 50 strokes to complete the final 500 meters of the race.
To find the answer to question 38, we need to find the team's mean split time and then reduce it by 10%. The mean split time is found by taking the total race time and dividing by 4, since there are 4 splits in the race.
Total race time = 440 seconds
Mean split time = Total race time ÷ 4 = 110 seconds
To reduce the mean split time by 10%, we multiply it by 0.9:
New mean split time = 110 seconds x 0.9 = 99 seconds
Therefore, at the end of the season, the team's mean split time should be 99 seconds.
