Answer:

Speed of hikers are 4.4 mph and 7.7 mph

Step-by-step explanation:

Two hikers are 55 miles apart and walking towards each other.

They meet after 10 hours.

Let the speeds of hikers are S and S' mph.

One hiker walks 3.3 mph faster than the other,

S = 3.3 + S'

S' = S - 3.3

Distance traveled by the hiker with higher speed S = Speed × Time

d_1=S\times 10

d_1=10S

Distance traveled by the slower hiker d_2 = (S - 3.3) × 10

Total distance between them = 55 miles

d_1+d_2=55

10S + 10(S - 3.3) = 55

20S - 33 = 55

20S = 88

S = 4.4 mph

Speed of first hiker = 4.4 mph

Speed of second hiker = 4.4 + 3.3 = 7.7 mph

notsponge [240]

Answer:

2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water

4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water

Step-by-step explanation:

1 batch

Yellow water = 3 teaspoons

Red water = 1 teaspoons

Yellow water : Red water = 3 : 1

2 batches of orange water

Multiply the ratios by 2

Yellow water : Red water

= (3 : 1) * 2

= 6 : 2

2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water

4 batches of orange water

Multiply the ratios by 4

Yellow water : Red water

= (3 : 1) * 4

= 12 : 4

4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water

Answer:

75\sqrt{2}(\sqrt{3}-1)

Step-by-step explanation:

In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.

In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have

x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)

Is -2 a solution to 4x^(3)-x^(2)+16x-4
sergiy2304 [10]

Answer:

Not a solution

Step-by-step explanation:

In order for x=-2 to be a solution, the result after substituting must be 0:

4(-2)^3-(-2)^2+16(-2)-4\stackrel{?}{=}0

4(-8)-4-32-4\stackrel{?}{=}0

-32-40\stackrel{?}{=}0

-72\neq0

Therefore, x=-2 is not a solution to 4x^3-x^2+16x-4
