Since a square has a complementary angle, it’s four angle in total is 360 degrees. But the angle b is given in the question and says what angle it was. So, angle b is 4x+10. What do we do about these numbers? We just created them into an equation and solve them algebraically. The way to solve it is this way:
4(4x+10) = 360
16x +40 = 360
16x= 320
X= 20

The answer is x= 20

A glacier in Alaska moves about 29.9 meters a day. About how much farther will mobe in 1,000 days than it will move in 100 days
Reptile [31]

Answer:

26,910 meters

Step-by-step explanation:

The glacier moves 29.9 meters a day.

In 100 days it will move 29.9(100)=2990 meters.

In 1000 days it will move 29.9(1000)=29900 meters.

29,900-2,990=26,910 meters

Select the simplification that accurately explains the following statement.<br> (from clever)
gavmur [86]

Answer:

OPTION C

Step-by-step explanation:

We know that $  (\textbf{x}^{\textbf{a}} )^{\textbf{b}} \hspace{5mm}  \textbf{=} \hspace{5mm} \textbf{x}^{\textbf{a . b}} $

Also, $ \textbf{x}^{\textbf{a}}. \textbf{x}^{\textbf{a}}  \textbf{=} \textbf{x}^{\textbf{a + a}} \textbf{=} \textbf{x}^{\textbf{2a}}  $

Using the above two results, we can say that:

$ \sqrt{9} = 9^{\frac{1}{2}} $

$ \bigg ( 9^{\frac{1}{2}} \bigg )^2 = 9^{\frac{1}{2}}. 9^{\frac{1}{2}} $

$ = 9^{\frac{1}{2} + \frac{1}{2}} $            (Using (ii) result)

$ = 9^{1} = \textbf{9} $

Hence, OPTION C is the correct answer.

Two truckers leave from the same point driving in opposite​ directions, the first trucker driving at 62 miles per hour and the s
Elodia [21]

Answer:

1 hour 42 minutes

Step-by-step explanation:

Given: Speed of 1st trucker= 62 mph

           Speed of 2nd trucker= 66 mph

           Total distance need to cover to be in contact is 270 miles

           1st trucker start 1 hour ahead of 2nd trucker

Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.

We know, distance= speed\times time

1st trucker, distance(d_1)= 62\times (x+1)

                     ∴ d_1= 62x+62

2nd trucker, distance(d_2)= 66\times x

                    ∴d_2= 66x

Now, putting the values in an equation.

d_1+d_2= 270

⇒ (62x+62)+66x= 270

Opening the parenthesis to solve and subtracting both side by 62

⇒ 122x= 208

∴ x= \frac{208}{122} = 1.70\ h = 1 hour 42 minutes

∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.
