Answer:

8 $\frac{3}{4} \\$

Step-by-step explanation:

Going from left to right on the number line we see that k is between 8 and 9. So 8 will be your whole number. The number line is divided into 8 sections between each whole number and k is located 6/8 between 8 and 9.

This mixed number is 8 6/8. We can reduce the 6/8 to 3/4 by dividing by 2 on the top and bottom. So your final answer is 8 3/4.

Answer:

8 and 3/4

Step-by-step explanation:

so there are 8 tic marks we know that there should be 10 so each tic mark is more than 1

8(x)=10

x=1.25

so each tic mark is 1.25 \

and since the K is on the 6th tic mark 1.25(6)=7.5 or 75%

or 8and 3/4 (in simplest form )

Cot(90° − x) = 1 The value of x that satisfies this equation is Blank °.

Reil [10]

Answer:

$x=90\degree$

Step-by-step explanation:

The given trigonometric equation is

$\cos(90\degree -x)=1$

We take the inverse cosine of both sides to obtain;

$(90\degree -x)=\cos^{-1}(1)$

$(90\degree -x)=0$

Group similar terms t obtain;

$-x=0-90\degree$

$x=90\degree$

To answer that question we need to use THE RULE OF THREE, this rule will help us solving linear relation problems.

Solution is:

The hour hand will turn (1/36)×π

The Table

Step minute hand hour hand

0-5 (1/6)×π (1/72)×π

10 (2/6)×π (1/36)×π

15 (3/6)×π = π/2 (1/24)×π

20 (4/6)×π = (2/3)×π (1/18)×π

25 (5/6)×π (5/72)×π

30 (6/6)×π = π (1/12)×π

35 (7/6)×π (7/72)×π

40 (8/6)×π (8/72)×π

45 (9/6)×π = (3/2)×π (3/24)×π

50 ( 10/6)×π ( 10/72)×π

55 (11/6)×π (11/72)×π

60 (12/6)×π = 2×π (12/72)×π = π/6

We know that each complete minute hand turn, is a 2×π angle turn, then a 5 minutes turn is (1/12) × 2×π = (π/6)
We will use that relationship to build the table and answer the question

If 2×π angle for a minute hand turn is equal to 1 hour, then

(2/6) angle for a minute hand turn is equal to "x" turn in the hour hand

So by Rule of Three, we proceed

2×π ( Of minute hand) ⇒ (1/6)×π (of hour hand)

(2/6)× π ( Of minute hand) ⇒ x

Solving for x

2×π × x = (2/6)× π × (1/6)×π

2× x = (2/36)×π

x = (1/36)×π

Now to build the table in 5 minutes steps:
