The measure of the Central Angle indicated is; 45°

<h3>How to find the central angle of a circle?</h3>

The central angle will be the angle subtended at the center by arc FE and arc CB.

Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;

Central Angle = 180° - 135° = 45°

Angle subtended by Arc CD at the center is;

θ = 180 - (81 + 45)

θ = 54°

Answer:

The number of different possible values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

Step-by-step explanation:

Given : For an integer n, the inequality $x^2 + nx + 15 < 0$ has no real solutions in x.

To find : The number of different possible values of n ?

Solution :

The given inequality is $x^2 + nx + 15 < 0$ have no solution then the discriminant must be less than zero.

i.e. $b^2-4ac$

Here, a=1, b=n and c=15

${n}^{2} - 4 \times 1 \times 15 \: < \: 0$

${n}^{2} - 60 \: < \: 0$

$n^2$

$n$

i.e. $- 7.75 \: < \: n \: < \: 7.75$

The integer values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

If two mammoths take seven hours to walk eleven kilometres, how long would it take five mammoths to walk twenty two kilometres a

kati45 [8]

This is a funny one. teachers do this to try to confuse you with the numbers. first you need to find out what is important in the question.

2 mammoths, 7 hours, 11 kilometers.
&
5 mammoths, ? hours, 22kilometers.

the amount of mammoths do not matter, because each walk the same speed.

so you only need to look at this.

7 hours to go 11 kilometers
&
? hours to go 22 kilometers

fast answer is. it's twice the distance so it will take twice as long. 14 hours.

solve answer.

7×60min = 420min
420min ÷ 11 kilometers = 38.18181818min per 1 kilometer.

38.18181818 • 22 = 839.999999min round up 840.

840min ÷ 60min = 14 hours
