63 + a = 90; subtract 63 from both sides of the equation.
Taya2010 [7]2 years ago

Answer:

Option B, 63 + a = 90; subtract 63 from both sides of the equation

Step-by-step explanation:

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Here, we  know the one angle measure is 63°

Let's consider unknown angle as a.

63 °+ a = 90°

63 °+ a -63° = 90° - 63° ( subtract 63 from both sides of the equation)

a = 90° - 63°

a = 27°

The houck family's train traveled 552 miles in 6 hours. The Roberts family traveled at 744 miles in 8 hours which family is trav
rusak2 [61]

Answer: Both families were travelling at the same speed/rate of 1mile/0.65mins or 1mile/0.01hr.

Step-by-step explanation: Speed of Houck family's train = 552m/6hrs

speed of Robert family's train = 744m/8hrs.

Therefore considering Houck speed,

552miles = 6hours

1mile = (6 x 60)/552

= 360/552

= 0.65minutes. Average speed = 1mile/0.65mins. Or 1mile/0.01hr

For Robert

744miles = 8hours

1mile = ( 8 x 60 )/744

= (480/744)minutes

= 0.645

= 0.65minutes. Average speed = 1mile/0.65mins. Or 1mile/0.01hr

Conclusion: Both families were travelling at the same speed/rate.

To get that minutes in hour, just divide by 60 to get concert to hours.

What is the range of y=log^2(x-6)
Marysya12 [62]

Answer:

y\geq 0 or [0, \infty)

Step-by-step explanation:

By definition the function

y = log (x) has a domain of x> 0.

Since the function is not defined for the values of x negative or equal to zero.

The range of this function is all the real numbers.

Since y when 0 and y\geq0 when 1\leq x

In this case we have the function y = log ^ 2 (x-6)

Therefore since the log function is squared then its range is now y\geq 0
