Explain why the formula for finding the area of a triangle makes sense in terms of the area of a rectangle? Thanks for helping:)

1 answer:

4 0

(I'll do my best to explain this:) ) if you put two triangles together they equal a rectangle. In other words if you split a rectangle from upper left corner to lower right corner you get two triangles. So if you multiply the triangle formula twice you get the rectangle formula.

Answer:

$\frac{45}{100}\\\\ \frac{9}{10}$

$\frac{10}{100} = 10%$

Step-by-step explanation:

125 % can be expressed as decimal as

$\frac{125}{100} \\\frac{25}{20} \\\frac{5}{4}$

Rule in changing Percent to decimal

a) Divide a percent by 100

b) Remove percent sign

45 %

$\frac{45}{100}\\\\ \frac{9}{10}$

$\frac{10}{100} = 10%$

Need help solving it. Quantitative Literacy.

1 lb ≈ 0.454 kg

1 in ≈ 2.54 cm

I'm not sure I understand the "do not" part of this question. What does it mean to convert from cubic inches (volume) to inches (length), and from centimeter to cubic centimeters?

In any case, you have

(1 lb)/(32.375 in³) ≈ (1 lb)/(3.19 in)³

… ≈ (1 lb)/(3.19 in)³ × (0.454 kg)/(1 lb) × ((1 in)/(2.54 cm))³

… ≈ (0.454 kg)/(3.19 in)³ × ((1 in)/(2.54 cm))³

… ≈ (0.454 kg) × ((1 in)/((3.19 in) × (2.54 cm))³

… ≈ (0.454 kg) × (1/(8.10 cm))³

… ≈ (0.454 kg) × 1/(530.531 cm³)

… ≈ (0.454 kg)/(530.531 cm³)

… ≈ 0.000856 kg/cm³
