Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
mide el ángulo de elevación nuevamente, ahora es de 40 grados. ¿Qué altura tiene
la montaña?
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Answer:
53.47
Step-by-step explanation:
yes, he can buy the backpack
88.95 x 0.40 = $35.48
88.95 minus 35.48 = 53.47
1.2% of 8th grade students is the percentage change.
First you find the common deoninator.
Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:Fraction: 5 / 6 it's already reduced to lowest terms
Fraction: 11 / 12 it's already reduced to lowest terms
Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:Denominator 6, factored = 2 * 3
Denominator 12, factored = 22<span> * 3</span>
LCM (6, 12) = 22<span> * 3 = 12</span>Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):For fraction: 5 / 6 is 12 : 6 = (22<span> * 3) : 6 = 2</span>
For fraction: 11 / 12 is 12 : 12 = (22<span> * 3) : 12 = 1</span>
Step 4: Expand fractions to bring them to the common denominator (LCM):5 / 6 = (2 * 5) / (2 * 6) = 10 / 12
<span>11 / 12 = (1 * 11) / (1 * 12) = 11 / 12</span>
