Answer:

Step-by-step explanation:

10-9+8×6÷(5-2^2)

Solve the parentheses and exponents (5-2^2) 5-4 =1

10-9+8×6÷1

Solve any multiplication 8×6 =48

10-9+48÷1

Solve any division 48÷1 =48

10-9+48

Solve any addition -9+48 =39

10+39

Solve 10+39

Answer:

Step-by-step explanation:

10 - 9 + 8 × 6 ÷ (5 - 2²)

Applying BODMAS (order of operations)

We solve what is in brackets first;

5 - 2² = 1 giving;

10 - 9 + 8 × 6 ÷ 1

We then divide to get;

10 - 9 + 8 × 6

We then multiply to get;

10 - 9 + 48

We then add to get;

58 - 9

By finally subtracting we get;

58 - 9 = 49

Suppose a triangle has two sides of length 2 and 3 and that angle between these two sides is 60 degrees. What is the length of t

Rudiy27

Answer:

The measure of the third side is $\sqrt{7}\ units$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

where

C is the angle between side a and side b

we have

$a=2\ units\\b=3\ units\\C=60^o$

substitute

$c^2=2^2+3^2-2(2)(3)cos(60^o)$

$c^2=13-(12)(\frac{1}{2})$

$c^2=13-6$

$c^2=7$

$c=\sqrt{7}\ units$

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 7, 18, 18, 15, 17, 10, 1

Serhud [2]

Answer:

Mean= 13.38

Median= 15

Step-by-step explanation:

The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students

Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8

= 107/8

= 13.38

The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers

7 , 7, 10, 15, 15, 17, 18, 18

Median = 15+15/2

= 30/2

= 15

Hence the mean is 13.38 and the median is 15

Graph the solutions of the inequality. X-3> 11 How do I know if the hole is open or close

34kurt

Answer:

x>14

Step-by-step explanation:

X-3> 11

Add 3 to each side

X-3+3> 11+3

x > 14

The hole is open at 14 since it is greater than

( it would be closed if it were ≥) The line goes to the right since it is greater than
