Question

thursday

1. round your answer to the nearest hundredth.

a small bag of flour weighed 19 ounces. a large bag was 18% heavier. how
much does the large bag weigh?

1. \\(\frac{\quad}{68} = \frac{25}{100}\\)
2. what is the ratio of triangles to

squares?

1. at the store brand a potato chips were $11.12 for 4 bags. brand b potato

chips were $19.74 for 7 bags. which brand has the cheaper price?

1. determine the greatest common factor (gcf).

6, 15
factors of 6 \\(\quad, \quad, \quad, \quad\\)
factors of 15 \\(\quad, \quad, \quad, \quad\\)

Explanation:

1)

Step1: Find 18% of 19

To find 18% of 19, we calculate \( 19\times0.18 = 3.42 \)

Step2: Add to original weight

The large bag's weight is the small bag's weight plus the additional weight, so \( 19 + 3.42 = 22.42 \)

Step1: Cross - multiply

Let the unknown number be \( x \). We have the proportion \( \frac{x}{68}=\frac{25}{100} \). Cross - multiplying gives us \( 100x=68\times25 \)

Step2: Solve for x

First, calculate \( 68\times25 = 1700 \). Then, divide both sides by 100: \( x=\frac{1700}{100}=17 \)

Step1: Count triangles and squares

Count the number of triangles (\( \triangle \)) and squares (\( \square \)). From the figure, the number of triangles is 5 and the number of squares is 11.

Step2: Write the ratio

The ratio of triangles to squares is the number of triangles divided by the number of squares, so the ratio is \( \frac{5}{11} \) or 5:11.

Answer:

22.42 ounces
