Answer:

11 mph

Step-by-step explanation:

Given that a man who can row in still water at 5 mph

The river is flowing at 6 mph.

We know that upstream speed = speed of man in still water - speed of river

and downstream speed = speed of man in still water + speed of river

So answer would be got by adding 5 and 6

=11 mph

The tile backslash will be a mixture of colors of five-inch square tiles. One quarter of the tiles will be "Indian Red" one sixt
Vladimir79 [104]

Answer:

The fraction of tiles that will be the color of "sand" is 23/60

Step-by-step explanation:

we know that

The sum of the fractions of the tiles must be equal to 1

Let

x ----> the fraction of tiles that will be the color of "sand"

we have that

\frac{1}{4}+\frac{1}{6}+\frac{1}{5}+x=1

solve for x

Find the Least Common Multiple of denominators

LCM=(2^2)((3)(5)=60

Multiply both sides by 60

\frac{60}{4}+\frac{60}{6}+\frac{60}{5}+60x=60

simplify

15+10+12+60x=60

60x=60-37\\60x=23\\x=\frac{23}{60}

therefore

The fraction of tiles that will be the color of "sand" is 23/60

Find the volume of the pyramid. Write your answer as a fraction or mixed number.
Dahasolnce [82]

Check the picture below.

let's notice that the base of the pyramid is triangle with a base of 5 and an altitude of 4, so it has an area of (1/2)(5)(4).

\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=\stackrel{\textit{area of its}}{base}\\ h=height\\[-0.5em] \hrulefill\\ B=\frac{1}{2}(5)(4)\\ h=8 \end{cases}\implies V=\cfrac{1}{3}\left( \cfrac{1}{2}(5)(4) \right)(8)\implies V=\cfrac{1}{3}(10)(8) \\\\\\ V=\cfrac{80}{3}\implies V=26\frac{2}{3}

Albert left his house on his bicycle riding at an average rate of 10 mph three hours before his son left by automobile his son o
ohaa [14]
In 3 hours, at 10 mph, Albert travels 30 miles. In 10 minutes (1/6 hr), while his son overtakes him, he travels 10/6 miles more, placing him at 30 + 10/6 = 190/6 = 95/3 mi.
His son covers 95/3 mi in 1/6 hr, so he's moving at (95/3)/(1/6) = 190 mph.
