Find the missing side of each right triangle. Side c is the hypotenuse. Sides a and b are the legs. Leave your answers in simple

vredina [299]

Answer:

Side b = 10.2 m (1 d.p.)

Step-by-step explanation:

11² = 121

15² = 225

225 - 121 = 104

√104 = 10.2 (1 d.p.)

Side b = 10.2m

(Full answer = 10.198039)

11² + 10.2² = 15²

Step-by-step explanation:

1) when x= 1/5

y = 1/5 + 1/2

y = 7/10

2) when x= 1/4

y = 1/4 + 1/2

y= 3/4

3) when x= 1/3

y = 1/3 + 1/2

y = 5 /6

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete wh

frozen [14]

Answer:

y = 2x + 20

$y\geq 20$

$x\geq 0$

Step-by-step explanation:

Vlad spent 20 minutes on history. Then Vlad spent 2 minutes on each math problem for homework, this is 2x. So in total, he spent 20+2x on homework. Depending on how many problems he did, the total time y can be found. This is the equation 20+2x=y.

If Vlad did 0 math problems then he spent at least 20 minutes on homework from history. This is the constraint $y\geq 20$ .

We also know Vlad can do many math problems but the least amount he did was 0, so the second constraint is $x\geq 0$ .
