What is the the answer to 6/12 x2/3

mr_godi [17]

To multiply two fractions together, multiply the numerators of both fractions together and same goes for the denominators.

$\frac{6}{12} * \frac{2}{3} = \frac{12}{36}$

Simplify.

$\frac{12}{36} = \frac{1}{3}$

So, 1/3 is the answer.

ou are standing 45 meters from the base of the Empire State Building. You estimate that the angle of elevation to the top of the

svetlana [45]

Answer:

443.2m

Step-by-step explanation:

Given in the question that,

distance from building to me = 45m

angle of elevation = 82°

building is 123 m + x m high

If we closely observe then this situation make a right angle triangle and we will use trigonometry identity to solve the question.

Step 1

tan(82) = y / 45

y = 45tan(82)

y = 320.2 m

Step 2

Hence the height of building is y + 123m. So, plug the value of y in this

320.2 + 123 = 443.2

Rearrange the equation so uuu is the independent variable. -12u+13=8w-3

Semmy [17]

Answer:

u = 8w-16 /-12 or = - 8w-16/12 both mean the same due to the a/-b- = -a/b rule. Then you can factor out the rest. note the fnew subtraction changes mean the same as - (a/b) and should show without brackets as a centre pointing whole fraction subtraction sign.

Step-by-step explanation:

-12u -13 = 8w-3

-12u+13 -13 = 8w-3-13 Eliminate -13 by +13 both sides

-12u = 8w-16 So you are left with one value left side.

-12u/-12 = 8/-12 - 16/-12 Then divide all values by -12 to find value for u and keep the subtraction as 8 never had subtraction sign and no multiplication .

u = 8w-16 /-12 Then you can factor out the rest

This has made u the independent variable then you have a choice to continue showing or ignore u; as u =

= - 8(w-2)/12 Step 1 Factor with subtraction change from -12 to - central fraction

= - 2(w-2)/3 Step 2 Simplify with new minus sign for central fraction to replace a/-b
