Gr 7 - Flashcard 1 - Lesson 10

Front

What is the equation to find the distance traveled if an elephant runs at a constant speed of 6 miles per hour?

Back

y = 6x, where y is the distance in miles and x is the time in hours.

Front

What is the formula to calculate the percent increase?

Back

Percent Increase = ((New Value - Original Value) / Original Value) * 100.

Front

What is the circumference of a circle with a radius of 4.5 feet?

Back

Circumference = 2πr = 28.26 feet.

Front

What does the slope of a line represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by b.

Front

Solve for x: 4x - 8x - 8 = 20.

Back

x = -7.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

What is the formula for calculating the area of a circle?

Back

Area = πr², where r is the radius.

Front

What does it mean for a line to have a negative slope?

Back

A negative slope means that as x increases, y decreases.

Front

What is the relationship between the radius and diameter of a circle?

Back

Diameter = 2 * Radius.
