Answer:
Option C.
Step-by-step explanation:
The given logarithmic equation is
It can be written as
Now, to check whether
is a true solution or not. Substitute
in the LHS of given equation.
Hence,
is a true solution because
.
Therefore, the correct option is C.
Let the bigger no. be X and the smaller no. be Y
X-Y=48
7-3=4
48÷4=12
X=12×7=84
Y=12×3=36
8 times is the correct answer!
A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour. How far does the puck slide in 10 seconds ?
(36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =
(36 x 1,000 x 10 / 3,600) meters = <em>100 meters</em>
What is the puck's speed in miles per hour ?
(36 km/hr) x (0.6214 mi/km) = <em>22.37 mi/hr</em>
both angles would equal the same so you have:
6x-57 = 2x+15
add 57 to each side:
6x = 2x+72
subtract 2x from each side:
4x = 72
divide:
x = 72/4 = 18
now replace x with 18:
6(18) - 57 = 51
2(18) +15 = 51
51 +51 = 102
Angle QNR = 102 degrees
