Answers
Answer:
3375 is the answer.
Step-by-step explanation: 8500- 1025=7475
so 1025 is every to years so we need to subtract 7475-1025-1025-1025-1025 so each 1025 is 2 yrs.

The side length of Cube B is twice that of Cube A.
The surface area of Cube B is not twice that of Cube A.
The volume of Cube B is not twice that of Cube A.
What is the surface area of a cube?
The surface area of a cube is the total of all of its covered faces. Six times the square of the cube's side length is the formula for surface area.
Here, we have
Given: Two larger cubes are made out of unit cubes. Cube A is 2 by 2 by 2. Cube B is 4 by 4 by 4. The side length of Cube B is twice that of Cube A.
Cube A is 2×2×2.
Cube B is 4×4×4.
The side length of Cube A is 2 and the side length of Cube B is 4. So, the side length of Cube B is twice that of Cube A.
The surface area of a cube is
Area = 6(side)²
Using this formula we get
Area of cube A = 6(2)² = 24
Area of cube B = 6(4)² = 96
96 is 4 times 24.
Hence, the surface area of Cube B is not twice that of Cube A.
The volume of a cube is
Volume = (side)³
Using this formula we get
The volume of cube A = (2)³ = 8
The volume of cube B = (4)³ = 64
64 is 8 times 8.
Hence, the volume of Cube B is not twice that of Cube A.

Learning Task 1. Tell whether each picture models a quadratic function or not.
Justify your answer.
GIVEN
Answer
WHY?
Answers
The picture for this question is given below.
Answer: All of them models quadratic function.
Step-by-step explanation: A quadratic function is of the form
f(x) = ax² + bx + c, with coefficient a≠0.
This function has a U-shape graphic called parabola. It has a vertex, i.e., a point where the curve changes, which is "classified" as minimum, if the parabola opens up; and as maximum, if the parabola opens down.
The y-intercepts are the points where the curve touches the y-axis and x-intercepts, if they exist, are the roots of the function.
The three pictures below shows three U-shaped curves opening down. This means the three parabolas are representation of 3 different quadratic functions, with a 3 vertex points that are maximum.
Quadratic functions are functions that follow a uniform curve path.
The first picture does not represent a quadratic function, while the other two pictures model a quadratic function.
To identify a quadratic function, we make use of the following observations.
The function must follow a uniform curved pathThe function must have a vertex i.e. maximum or a minimumThe function must be represented as: [tex]\mathbf{y = ax^2 + bx + c}[/tex]From the question (see attachment for pictures), we can see that:
The first picture models several quadratic functions, because several uniform curves are represented on the picture.The second and the third picture model exactly one quadratic function, because both pictures have a uniform curve, and they have a single maximum point.Hence, the first picture does not represent a quadratic function, while the other two pictures model a quadratic function.

The missing value is 2000 .
How to calculate the percentage of an amount ?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we imply that it is 50% of everything.As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any topic are calculated in terms of percentages in academics.Calculations :
= Based on the given conditions, formulate = 40/20%
= Convert the percentage to decimals = 400/0.2
= Multiply both the numerator and denominator
with the same integer = 4000/2
= Cross out the common factor = 2000

In ΔHIJ, i = 53 cm, ∠I=120° and ∠J=30°. Find the length of j, to the nearest 10th of a centimeter.
Answers
Answer:
30.6
Step-by-step explanation:
The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The length of the side j is 30.6 cm.
What is Sine rule?The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]
where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
Given the length of i is 53 cm, while the measure of the ∠I is 120°. Also, the measure of ∠J is 30°. Therefore, the length of the side j is,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}\\\\\dfrac{Sin\ I}{i} =\dfrac{Sin\ J}{j} \\\\\dfrac{Sin\ 120^o}{53} =\dfrac{Sin\ 30^o}{j} \\\\j = \dfrac{Sin\ 30^o \times 53}{Sin\ 120^o}\\\\j = 30.5995 \approx 30.6\rm\ cm[/tex]
Hence, the length of the side j is 30.6 cm.
