Answer:

5.7m

Step-by-step explanation:

the easiest way to solve for a side is to draw the question in a diagram (i have done this below). As it is a right-angled triangle and we know 2 of the side, we can use the Pythagoras theorem:

a^{2} +b^{2} =c^{2}

sides a and b are the two shorter sides.

side c is the hypotenuse (longest side)

as shown in the picture below, because we know both sides c and b, we need to change the equation around:

c^{2} -b^{2} =a^{2}

replace these sides with their numbers:

6^{2} -2^{2} = 32 (remember that 32 equals side a squared therefore we need to square root 32 to find the length of side a:

\sqrt{32} =5.65685...

the question says to round to the nearest tenth meter:

Missing side = 5.7m

I hope this was helpful :-)

Kristian buys a meal for $8.40 calculate the fraction of the $72 after buying the computer game which costed $32.40 and the meal
brilliants [131]

Answer:

After buying the meal and the computer game, Kristian has 43.33% of his money left.

Step-by-step explanation:

Given that Kristian buys a meal for $ 8.40, to calculate the fraction of the $ 72 after buying the computer game which cost $ 32.40 and the meal, the following calculation must be performed:

72 = 100

8.40 + 32.40 = X

72 = 100

40.80 = X

40.80 x 100/72 = X

4,080 / 72 = X

56.66 = X

100 - 56.66 = 43,333

Therefore, after buying the meal and the computer game, Kristian has 43.33% of his money left.

Help with this question please! Give explanation! Big points
BigorU [14]

Answer:

y = 2

Step-by-step explanation:

This answer is easily found using the Pythagorean Theorem:

{a}^{2}  +  {b}^{2}  =  {c}^{2}

where A and B are the legs, and C is the hypotenuse of the triangle.

{(16)}^{2}  +  {(6y)}^{2}  =  {(10y)}^{2}  \\ 256 +  36{y}^{2}  = 100 {y}^{2}  \\ 256 = 64 {y}^{2}  \\  \sqrt{256}  =  \sqrt{64 {y}^{2}} \\ 16 = 8y \\ y = 2
