In this case, to determine 10% of 90, you would perform the following calculation: Calculation: 10% of 90 = 90 x 0.10 Now, let’s perform the multiplication: 90 x 0.10 = 9 Therefore, 10% of 90 equals 9. This method can … Read more
To solve the quadratic equation 7x² + 7 = 0, we first need to rewrite it in the standard quadratic form, which is ax² + bx + c = 0. In this case: a = 7 b = 0 c = 7 Next, we can use the quadratic formula, which is: x = (-b ± … Read more
In the realm of algebra, an equation that possesses only one solution is typically classified as a linear equation. More specifically, this happens when the equation is of the form: ax + b = c where: a is a non-zero constant, which guides the slope of the line. b and c are constants that adjust … Read more
The equation given is 3x + 4y = 8. To find the solutions, we need to express it in terms of y or x. Rearranging the equation for y: 4y = 8 – 3x y = (8 – 3x) / 4 Now, we can substitute different values of x into this equation to see what … Read more
To determine if a graph is symmetric with respect to the origin, you can follow these steps: Understand the concept: A graph is symmetric with respect to the origin if, for every point (x, y) on the graph, the point (-x, -y) is also on the graph. This means that the graph will look the … Read more
To find out what 15 of 70 means, we need to interpret it as a fraction or percentage. In this case, we can look at it in two main ways: 1. As a Fraction: The phrase ’15 of 70′ can be expressed mathematically as: 15/70 When you divide 15 by 70, you’re essentially asking how … Read more
The sequence given is: 9, 3, 1, 1, 3. To solve for the next number in the sequence, let’s first analyze the pattern: The first number is 9
The number of significant figures in a number is crucial for precision in measurements. In the case of the measurement 1050l (assuming the ‘l’ is a typographical error for a number), we analyze each part of the number to determine the significant figures. For the number 1050, it appears initially that we have four digits. … Read more
To prove that the diagonals of a parallelogram with equal adjacent sides and one diagonal equal to a side are in the ratio of √3:1, we can follow these steps: Understanding the parallelogram properties Let’s denote the parallelogram as ABCD where AB = BC (adjacent sides are equal). Since we have mentioned that one diagonal … Read more
To determine how many spaces are filled in a parking lot that holds 1,600 cars and is filled to three-fourths of its capacity, we can follow a simple calculation. First, we need to find three-fourths of 1,600. This can be calculated by multiplying 1,600 by the fraction 3/4. Here’s the calculation: 1,600 x (3/4) = … Read more
