• Rewriting the question knowing these facts get us: 2 x 9 - 2
• Using the Order of Operations, we multiply first getting us 18 - 2
• Final answer is 16.

Shawn waited at the bus stop for 15 min and saw 39 vehicles
go past. He counted a total of 124 wheels and noticed that only
cars and motorcycles went past. How many cars went past Shawn?

Answers

Step-by-step explanation:

let no of motorcycles be m and no of cars be c

4c + 2m = 124 --(1)

c + m = 39

c = 39 - m --(2)

sub (2) into (1):

4(39 - m) + 2m = 124

156 - 2m = 124

2m = 32

m = 16

therefore, c = 23

23 cars

The speed of a boat in still water is 25 mph. The boat is traveling on a river with a current flowing south at 10 mph. At what angle upstream should the boat head to travel due west?

21.80°
23.58°
66.42°
68.20°

Answers

Answer:

B. 23.58

Step-by-step explanation:

I got it right

The correct option is an option (b).

Angle of upstream:

If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed

Given that [tex]sin\theta=\frac{10}{25}[/tex]

Then the angle [tex]\theta[/tex] will be,

[tex]\theta= sin^{-1}(\frac{10}{25} )\\\theta=23.578[/tex]

The boat would need to be angled by about 23.58° upstream to travel due west.

Mathematics

Answers

Answer:

h = 9 but see note below.

Step-by-step explanation:

Givens

h = ?

L = h + 31

diagonal = 41

Formula

h^2 + (h+31)^2 = 41^2

h^2 + h^2 + 62h + 961 = 1681

2h^2 + 62h + 961 = 1681

2h^2 + 62h + 961 - 1681 =0

2h^2 + 62h - 720 = 0

h^2 + 31h - 360 = 0

(h - 9) ( h + 40) = 0

h + 40 has no meaning

h - 9 = 0

h = 9

I suppose you might have to answer it as 9.0
