Step-by-step explanation:

here, let the number be x

x = (520/100) × 100 (since % means-divide by 100)

x = 520

Answers

Answer:

Step-by-step explanation:

Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.

Note: c is the hypotenuse of the triangle.

18 + 18 = c^2

= 36 = c^2

Therefore, c = 6.

i’ll give u brainliest!! what is the area of shape 1 2 and 3

Answers

Answer:

Shape 1: 197.04

Shape 2: 125.44

Shape 3: 62.72

Step-by-step explanation:

For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.

The one on the top right side

Step-by-step explanation:

A graph with a negative slope is a graph that "decreases" in y value when the x values "increases".

I'm the top right graph, the y value changes from 8 to 6, the x value changes from 0 to 4.

Also if you trace the 1 on the x axis upward until it touches the graph , you'll see that , that's where you'll see the 6 on the y axis. That's why The graph passes through (1,6).

Determine the solution to the system of equations.

Equality Properties

Algebra I

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingTerms/Coefficients

Step-by-step explanation:

Step 1: Define Systems

3x - y = 9

2x - y = 6

Step 2: Rewrite Systems

2x - y = 6

Subtract 2x on both sides: -y = 6 - 2xDivide -1 on both sides: y = 2x - 6

Step 3: Redefine Systems

3x - y = 9

y = 2x - 6

Step 4: Solve for x

Substitution

Substitute in y: 3x - (2x - 6) = 9Distribute -1: 3x - 2x + 6 = 9Combine like terms: x + 6 = 9Isolate x: x = 3

Step 5: Solve for y

Define equation: 2x - y = 6Substitute in x: 2(3) - y = 6Multiply: 6 - y = 6Isolate y term: -y = 0Isolate y: y = 0

Step 6: Check

Graph the systems to verify the solution set (3, 0) is the solution.

The solution set to the systems would be where the 2 lines intersect.

We see that the intersection point is x-intercept (3, 0).

∴ (3, 0) is the solution set to the systems of equations.
