Forty is 25% of what number?

Answers

Since it is 25% all you would have to do is mutiply it by 4 to get 160. So in conclusion 160 is the answer.
40 is 25% of 160 because 25% is the same as 1/4 and 1/4 of 160 is 40

Suppose you are doing a 5,000 piece puzzle. you have already placed 175 pieces. Every minute you place 10 more pieces. Write and equation in slope intercept form to model the number of pieces placed. Is this relationship linear, how do you know?

Answers

y=mx+b

5,000=10x+175

Where x equals minutes spent working on the jigsaw. 

Final answer:

The equation modelling the given scenario in slope-intercept form is y = 10x + 175, which represents a linear relationship because the rate at which puzzle pieces are being placed,10 per minute, is constant.

Explanation:

The subject of your query falls into the category of linear algebra, specifically, slope-intercept form equations and linear relationships in mathematics. In slope-intercept form, a line can be described by the equation y = mx + b, where 'm' represents the slope and 'b' signifies the y-intercept.

For your puzzle scenario, 'm' is the number of puzzle pieces you place each minute, which is 10, and 'b' is the initial number of pieces already placed which is 175. Therefore, the equation that models your situation is y = 10x + 175.

This relationship is, indeed, linear. We know this because the rate at which you are placing puzzle pieces is constant, meaning it doesn't change over time. This is characteristic of a linear relationship, as represented by the straight line on a graph. In other words, for every unit increase in time (x), the number of puzzle pieces placed (y) increases at a steady rate of 10.

 Where,
 (xo, yo): It's an ordered pair either.
 m: is the slope of the line.
 We observe that for a point (xo, yo) infinite lines with different slope m can pass.
 Answer:
 The conclusion is that for the ordered pair (xo, yo) can pass infinite lines that satisfy:
 y-yo = m (x-xo)

What is the measure of angle x?

Answers

Answer:

x = 47°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for x

x = 180° - (31 + 102)° = 180° - 133° = 47°

Answer:

Step-by-step explanation:

180-(102+31) (asp)

=180-133

=47
