Answer:

11.5 hours

Step-by-step explanation:

25 pages every 75 minutes (1 1/4)

Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)

230 pages would mean 690 minutes (times the 3 by 230)

690/6 = 11.5

\tan \left(18\right)=\frac{x}{20}
noname [10]

Answer:

x ≈ 6.5

Step-by-step explanation:

We have the epresion tan(18)=\frac{x}{20} and we want to find the value of x.

Let's do it step-by-step

Step 1. Multiply both sides of the equation by 20

tan(18)=\frac{x}{20}

20tan(18)=(\frac{x}{20} )(20)

20tan(18)=x

Step 2. use the reflexive property of equality: if a=b then b=a

20tan(18)=x

x=20tan(18)

Step 3. Using a calculator we get that tan(18)=0.325.  Replacing that value we get

x=20(0.325)

x ≈ 6.5

We can conclude that the value of x is approximately 6.5

Two angles in a triangle have measures of 25° and 55°.
rosijanka [135]

Answer:

B) 100

Step-by-step explanation:

All 3 interior angles of a triangle add up to 180 so:

x + 25 + 55 = 180

x + 80 = 180

x = 180 - 80

x = 100

(c) One lorry travels from your town to another town. The lorry reaches a top speed
Katen [24]

Answer:

The average speed is 24 km/h less than the top speed of the lorry.

Step-by-step explanation:

The top speed of the lorry is the highest speed reached during transit, while its average speed is the mean speed attained

Given:.

Top speed of the lorry = 90 km/h

Average speed of the lorry = 66 km/h

Then,

The difference between the speed reached = top speed - average speed

                                            = 90 - 66

                                            = 24 km/h

Therefore, the average speed is 24 km/h less than the top speed of the lorry.
