Pls help me solve this ​
sammy [17]

Answer:

4 kg of sugar would contain 1.2 \times 10^9 crystals.

Step-by-step explanation:

Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.

Thus, set up a proportion as follows:

3 kg : 9 × 10⁸ = 4 kg : x

\frac{3}{9 \times 10^8} = \frac{4}{x}

Solve for x. Cross multiply.

3 \times x = 9 \times 10^8 \times 4

3x = 36 \times 10^8

3x = 3.6 \times 10^9

Divide both sides by 3

\frac{3x}{3} = \frac{3.6 \times 10^9}{3}

x = 1.2 \times 10^9

4 kg of sugar would contain 1.2 \times 10^9 crystals.

Komok [63]

Answer:

A dilation stretches or shrinks the original figure. A description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch).

Jordan and Erica both walk to school. 3/4 of the distance that
lys-0071 [83]

The person whose walk is longer is Erica.

Erica's walk is 8/9 times longer than Erica's walk.

<h3>Whose walks the longer distance?</h3>

In order to determine who walked the longer distance, we would convert the fractions to percentages.

3/4 becomes 75%

2/3 becomes 66.7%

Erica's percentage is smaller, thus, she walks a longer distance.

Jordan's walk is 8/9 times longer

(2/3 ÷3/4) (2/3 x 4/3 = 8/9)
