Answer:
im guessing you wanted me tho find the common denominator of 7 8/10 and 1 1/4 the LCD would be 20.
Step-by-step explanation:
Solution:
Rewriting input as fractions if necessary:
78/10, 5/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
78/10 = 78/10 × 2/2 = 156/20
5/4 = 5/4 × 5/5 = 25/20
Answer:
D
Step-by-step explanation:
Given
(x + y + 2)(y + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(y + 1) + y(y + 1) + 2(y + 1) ← distribute parenthesis
= xy + x + y² + y + 2y + 2 ← collect like terms
= y² + xy + x + 3y + 2 → D
To calculate the probability of each event occurring you will need to know there are 7 consonants and 3 vowels. You will use this to find the probability of each set of events occurring and multiply them together.
a. 1/10 x 1/9 = 1/90 chance
b. 3/10 x 1/9 = 1/30 chance
c. 7/10 x 2/9 = 7/45 chance
d. 3/10 x 7/9 = 7/30 chance
Answer:
tienes que sumar dos veces 2370 y despues dividirlo
Step-by-step explanation:
since it is right-angled, first of all Pythagoras :
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90 degree angle).
so,
8.3² = 8² + HI²
HI² = 8.3² - 8²
HI = sqrt(8.3² - 8²) = sqrt(68.89 - 64) = sqrt(4.89)
alternative : the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
with the sides are always opposite of the associated angles.
angle G = 180 - 90 - 75 = 15° (as the sum of all angles in a triangle is always 180°).
so,
8.3/sin(90) = 8.3/1 = HI/sin(15)
HI = 8.3 × sin(15)
another alternative would be the extended Pythagoras for non-right-angled situations. like making HI the baseline, although the opposing angles G is not 90°.
c² = a² + b² - 2ab×cos(C)
C being the angle opposite of c.
HI² = 8.3² + 8² - 2×8.3×8×cos(15) = 132.89 - 132.8×cos(15)
HI = sqrt(132.89 - 132.8×cos(15))
