Answer:
The value of x is 11.
Step-by-step explanation:
The given number is 0.27272727..., and it is converted to the fraction as
..... (1)
Multiply both sides by 100.
.... (2)
Subtract equation (1) from equation (2),
Multiply both sides by x.
Divide both sides by 27.
Therefore the value of x is 11.
Answer:
In step A, you replace all trigonometric functions with their definitions in terms of sine and cosine.
In step B, you add the two together as you add fractions.
In step C, you replace 1 with the sum of the squares of sine and cosine.
In step D, you add the cosine terms together so they disappear.
In step E, finally, you divide numerator and denominator by .
Answer:
A) No
B) Yes
C) Yes
D) Yes
Step-by-step explanation:
A) No, 2,000 km is not equal to 2 m. In fact 2000 Km is equal to 2000000 m
B) Yes, 1 meter is equal to 1000 millimeter hence, 2m will have 2,000 mm
C) Yes, 1 cm is equal to 10 mm. Thus, 20 cm will have 200 mm
d) Yes, 1 m is equal to 100 centimeter. Thus, 20 m is equal to 2,000 cm
1 gallon = 4 quarts
1 Quart = 2 pints
1 Pint = 2 cups
2 (amount of pints in a quart) x 5 (amount of quarts) = 10 = how many pints
10 x 2 (amount of cups in a pint) = 20
20 = how many cups in 5 quarts
The measurement of angle a plus 120 must equal to 180 ( as angles on a straight line must equal to 180)
So measurement of angle a is 60 degrees
Measurement of angle b plus 60 plus 60 must equal to 180
So measurement of angle b is 60
