Answer:

The surface area increases by 4 times.

Step-by-step explanation:

square root of 288 = 16.970562.... (= 1 side)

1 side(x2) = 33.941125...... (= double of the side)

New area = new side squared

(33.94111....) squared =  1,152 (new area)

1,152/288 = 4    

new area is 4 times bigger

288 x4 = 1,152

Based on the amount of wheat exported by Canada and Mexico, the number of times more wheat exported by Canada over Mexico is 0.26 times.

This can be found by the formula:

= Amount of wheat exported by Canada / Amount of wheat exported by Mexico

Solving gives:

= (2.21 x 107) / (8.5 x 105)

= 236.47 / 892.5

= 0.26 times

Answer:

2/3x + 1/6x = 30

x represents her money, because it is unknown

and 30 represents the leftover money she was left, so we solve for x.

x - (2/3x + 1/6x) = 30

Combine multiplied terms into a single fraction.

Find a common denominator;

x - 4/6x - 1/6x = 30

Combine fractions with common denominator.

Multiply all terms by the same value to eliminate fraction denominators;

6x - 4x - 1x / 6 = 30

Cancel multiplied terms that are in the denominator.

x/6 = 30

Multiply them.

To get,

x = 180

Jessica had 180 dollars in her pocket before shopping.

Two or more expressions with an Equal sign is called as Equation.

Let's assume that Jessica had 'x' dollars in her pocket before going shopping.

Jessica used 2/3 of her money to buy books, which is (2/3)x dollars.

She used 1/6 of her money to buy notebooks, which is (1/6)x dollars.

So, the total amount of money spent on books and notebooks is:

(2/3)x + (1/6)x = (4/6)x + (1/6)x = (5/6)x

Jessica had 30 dollars left in her pocket after shopping. So, we can write:

x - (5/6)x = 30

Simplifying the equation, we get:

(1/6)x = 30

Multiplying both sides by 6, we get:

x = 180

Therefore, Jessica had 180 dollars in her pocket before shopping.

Answer:

(-3,5)

Step-by-step explanation:

Answer:

Suppose the slope of a line were to decrease. Then it would get flatter. These conditions are true whether or not the slope was positive or negative to begin with. A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line.

For a decreasing function, the slope is negative. The output values decrease as the input values increase. A line with a negative slope slants downward from left to right as in (b). If the function is constant, the output values are the same for all input values so the slope is zero.
