The area of the square is increasing at a rate of 8 cm²/s when the area of the square is 16 cm².
When the side length of a square increases, the area of the square also increases. The formula for area of a square is side length multiplied by itself.
Therefore, when the side length of a square increases at a rate of 2 cm/s, the area of the square increases at a rate of 2 cm/s multiplied by 2 cm/s, or 4 cm²/s.
However, since the side length of the square is 16 cm when the area of the square is 16 cm², the rate at which the area of the square increases is 2 cm/s multiplied by 16 cm, or 8 cm²/s.

Kiara bought a box of cereal that weighs 1 7/16 pounds. During one week, she user about 1/2 of a pound of the cereal. Which are two reasonable estimates for how much,in pounds,the box of cereal weighs now
The box of cereal now weighs approximately 0.9 pounds and 1.3 pounds.
To estimate the weight of the cereal in the box now, we must subtract the amount of cereal used during the week from the total weight of the box when Kiara bought it.
The total weight of the box when Kiara bought it is 1 7/16 pounds. To convert this fraction to a decimal, divide the numerator (7) by the denominator (16): 7/16 = 0.4375.
The amount of cereal used during the week is 1/2 of a pound. To convert this fraction to a decimal, divide the numerator (1) by the denominator (2): 1/2 = 0.5.
Subtract the amount of cereal used from the total weight of the box: 0.4375 - 0.5 = -0.0625.
Since the result is negative, we can approximate the weight of the cereal in the box now as 0.9 pounds. We can also round the result to the nearest hundredth: 0.4375 - 0.5 = -0.0625 = 0.94 pounds.

The scale on the map is 1:25000
How many kilometres on the ground is represented by 6cm on the map?
Answer: 150,000 km
Step-by-step explanation: If every centimeter is equal to 25000 kilometers, than 6 x 25000 = 150,000.
Answer:
1.5 km
Step-by-step explanation:
1 kilometer = 1000 meters and 1 meter = 100 cm, so 1 km = 100,000cm
If the scale on the map is 1:25,000, 6cm on the map = 150,000 cm
Since 1 km = 100,000 cm, 1 km/100,000 cm = 1
150,000 cm x 1 km/100,000 cm = 1.5 x 1km = 1.5 km

Define simultaneous equationSimultaneous equations refer to a set of two or more equations that need to be solved together to determine the values of the variables that satisfy all the equations.
Given:
y = -x²+ 2x + 4
x + y = 4

Simplifying, we get:
-x² + 3x = 0
Factorizing, we get:
x(-x + 3) = 0
So the possible values of x are x = 0 and x = 3.
If x = 0, then y = 4 (from the second equation).
If x = 3, then y = -3 (using the first equation).
Therefore, the solution set of the system of equations is (0, 4) and (3, -3).

ajay decides to research the relationship between the length in inches and the weight of a certain species of catfish. he measures the length and weight of a number of specimens he catches then throws back into the water. after plotting all his data, he draws a line of best fit. what does the slope of the line represent?
The slope of the line of best fit represents the change in the average weight of the catfish for every one-unit change in the length of the catfish. It gives an indication of the strength and direction of the relationship between the length and weight of the catfish.
A positive slope indicates that as the length of the catfish increases, its weight tends to increase as well, while a negative slope indicates the opposite. The magnitude of the slope indicates how steeply the weight changes with respect to the length. A larger slope indicates a stronger relationship, while a smaller slope indicates a weaker relationship.
Thus, the slope of the line of best fit can provide valuable insights into the relationship between the length and weight of the catfish and can be used to make predictions about the weight of the catfish for a given length.

The equation is true, which means the given triangle is a right triangle.
What is triangle?A triangle is a geometric shape that is formed by connecting three non-collinear points with straight line segments. These points are called vertices of the triangle, and the line segments are called sides. The angles formed by the intersection of these sides are called interior angles of the triangle. Triangles are used in many areas of mathematics, including geometry, trigonometry, and calculus. They also have practical applications in fields such as engineering, physics, and architecture, where they are used to calculate measurements and solve problems involving angles and distances.
Here,
To determine whether the triangle is a right triangle or not, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the lengths of the sides are given as 8 cm, 10 cm, and 12 cm. We can check if this triangle is a right triangle by verifying if the Pythagorean theorem holds true.
Let's label the sides as follows:
a = 8 cm (one of the legs)
b = 10 cm (the other leg)
c = 12 cm (the hypotenuse)
According to the Pythagorean theorem, we have:
c² = a² + b²
Substituting the given values, we get:
12² = 8² + 10²

CE= 6x, and m
Find x.
The diameter of circle C is [tex]x[/tex], which is [tex]5[/tex].
What in geometry is a circle?A circle is the collection of all points on a plane that are at a specified distance from another point (the radius) (the centre). A radius is any distance separating a point on a circle from its center. Any two radii are equal in length under the concept of a circle.
What do you call a half circle?A semicircle is a half circle produced by splitting a circle into two equal parts. It is created when a line pierces the circle's center and touches its two ends.
Since [tex]CE[/tex] is a radius of the circle and the diameter is [tex]30[/tex] units long, we know that [tex]CE[/tex]is half the length of the diameter:
[tex]CE = 1/2[/tex](diameter)[tex]= 1/2([/tex]30 units)[tex]= 15[/tex] units
We are given that [tex]CE = 6x[/tex], so we can solve for [tex]x[/tex]:
[tex]CE = 6x = 15[/tex]
[tex]x = 15/6[/tex]
[tex]x = 2.5[/tex]
Now, we can use the fact that angle [tex]CED[/tex], where [tex]D[/tex] is the center of the circle, is a central angle that intercepts arc [tex]CD[/tex], to find the measure of angle [tex]CED[/tex].
Since the diameter of the circle is a straight line, it forms a [tex]180[/tex] degree angle at its endpoints. Therefore, angle [tex]CED[/tex] is half of this angle, which is:
angle [tex]CED = 1/2(180 degrees) = 90[/tex]degrees
We are given that angle [tex]CED[/tex] is [tex]30[/tex] degrees, so we can set up an equation:
angle [tex]CED = 30 = 6x[/tex]
Simplifying and solving for [tex]x[/tex]:
[tex]6x = 30[/tex]
[tex]x = 30/6[/tex]
[tex]x = 5[/tex]

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
