Sharing £900 in the ratio of 3:7 is equal to £270 and £630.
<u>Given the following data:</u>
- Total amount = £900.
- Ratio = 3:7
- Sum of ratio =
= 10.
To share £900 in the ratio of 3:7:
<h3>How to calculate a ratio.</h3>In this exercise, you're required to share the total amount of money in the ratio of 3:7. Thus, we would solve as follows:
<u>For a </u><u>ratio</u><u> of </u><u>3</u><u>:</u>
Amount = £270.
<u>For a </u><u>ratio</u><u> of </u><u>7</u><u>:</u>
Amount = £630.

Answer:
<em>6 cm </em>
Step-by-step explanation:
<u><em>I don't know may I use the trigonometry functions, therefor I'm going to use Pythagorean theorem and property of 30°-60°-90° triangle.</em></u>
m∠ACB = 120° ⇒ m∠ACD = 60° ⇒ m∠DAC = 30°
DC is opposite to 30° angle ⇒ AC = CB = 8 cm
From ΔADC: AD² = 64 - 16 = 48 ; AD = 4√3 cm
ΔACB is isosceles ⇒ m∠CAB = m∠CBA = 30°
m∠DAH = m∠DAC + m∠CBA = 2(30°) = 60° ⇒ m∠ADH = 30° ⇒ AH = 4√3 ÷ 2 = 2√3 cm
From ΔADH: <em>DH</em> = = √36 = <em>6 cm</em>
Answer:
Step-by-step explanation:
<u>Given number:</u>
29,980,000,000
<u>Rules:</u>
- Move the decimal point after the first non-zero digit. (after 2)
- Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
- Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).
<u>The number will become:</u>
2.998 × 10¹⁰
