Answer: 12km

Step-by-step explanation:

To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.

So your formula would be 4^2 + 3^2 = c^2 ...

16 + 9 = c^2

25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.

Answer:

x=-5/2,4

Step-by-step explanation:

Given:

The sides of a triangles in the options.

To find:

Which of the following cannot be the lengths of the sides of a triangle?

Solution:

In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.

For option A,

[tex]6+8=14>12[/tex]

For option B,

[tex]4+4=8>12[/tex]

For option C,

[tex]6+6=12[/tex]

Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.

For option D,

[tex]6+8=14>10[/tex]

Therefore, the correct option is C.

Step-by-step explanation:

m(x + n) = n

mx + mn = n

mx = n - mn

x = (n - mn)/m

x(a + b) = b(c - x)

ax + bx = bc - bx

ax + bx + bx = bc

x(a + b + b) = bc

x(a + 2b) = bc

x = bc/(a + 2b)

mx = n(m + x)

mx = mn+ nx

mx - nx = mn

x(m - n) = mn

x = mn/(m-n)

Answer:

8.48%

Step-by-step explanation:

Bill's weight decreases from 64.8 kg to 59.3 kg.

We need to find the percentage decrease in Bill's weight. It can be calculated as follows :

[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]

So, the required decrease in percentage is 8.48%.

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

Answer:

n =[tex]\frac{5}{10}[/tex]

Step-by-step explanation:

Answer:

n= 2 and two thirds

Step-by-step:

this is the equation

3/10n=4/5

so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Answer:

16

Step-by-step explanation:

By the property of intersecting chords inside the circle, we have:

[tex](5x - 7) \degree = \frac{1}{2} (119 \degree + 27 \degree) \\ \\ (5x - 7) \degree = \frac{1}{2} \times 146 \degree\\ \\ (5x - 7) \degree = 73\degree \\ \\ 5x - 7 = 73 \\ \\ 5x = 73 + 7 \\ \\ 5x = 80 \\ \\ x = \frac{80}{5} \\ \\ x = 16[/tex]

Answer:

The markup formula is as follows: markup = 100 * profit / cost .

Step-by-step explanation:

For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.

How do you calculate a 45 markup?

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

Answer:

x=-2

Step-by-step explanation:

5x+4=-6 so basically what you want to do is try to get x by itself

step 1 subtract 4 from each side

5x=-10

step 2 divide each side by 5

x=-2

Answer:

K=24

B=21

Step-by-step explanation:

x+x-5=43

2x=48

x=24

K=24

B=21

Answer:

24

Step-by-step explanation:

So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

Answer:

X = 4.47  Y = 8.94

Step-by-step explanation:

2[tex]\sqrt{5}[/tex]= 2.23606798

2.23606798 x 2 = 4.47213596

-------

4.47213596

4.47213596^2 + 4.47213596^2 = 8.94427192^2

8.94427192^2 = 80

Square root of 80 is 8.94
