So you have to double the numerator of the fraction which is 4 times 2 equals 8 so it’s 8/5 miles per hour or 1.6 mph

Answer:

20 kilograms of dough

Step-by-step explanation:

Given that;

12 kilograms working 6 hours

Rate = 12/6 kilogram per hour = 2 kilogram per hour

So,

In 10 hours he would produce;

Amount of dough = Time × rate

Time = 10 hours

= 10 hours × 2 kilograms per hour

= 20 kilograms of dough

Answer:

x = 1

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are in proportion, that is

$\frac{x}{x+2}$ = $\frac{9}{27}$ = $\frac{1}{3}$ ( cross- multiply )

3x = x + 2 ( subtract x from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

This time it's cosine.

Cosine is the adjacent/hypotenuse. In this case, the adjacent is 15 and hypotenuse is 21.

15/21, or like 5/7.

Now put that into a fancy calculator with the $cos^{-1}$ thing or something like that and then you have the answer, or around 44 degrees.
