Well 15% of £20 is three so maybe add that onto 20?

What is 0.002 one tenth of.

jeka94

Let's say is "x".

so, "x" is the whole or 10/10 whilst 0.002 is 1/10 then, let's check

$\bf \begin{array}{ccll}
amount&fraction\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
0.002&\frac{1}{10}\\\\
x&\frac{10}{10}
\end{array}\implies \cfrac{0.002}{x}=\cfrac{\frac{1}{10}}{\frac{10}{10}}\implies \cfrac{0.002}{x}=\cfrac{\frac{1}{10}}{1}
\\\\\\
\cfrac{0.002}{x}=\cfrac{1}{10}\implies \cfrac{0.002\cdot 10}{1}=x$

Miya is picking up two friends to go the beach. She drives from her house to

Serga [27]

Answer:

Option (C)

Step-by-step explanation:

Coordinates of the point representing the location of Miya → (1, 10)

Coordinates of the point representing the location of Drea → (13, 1)

Coordinates of the point representing the location of Francine → (16, 1)

Coordinates of the point representing the location of Beach → (19, 4)

Distance between Miya and Drea = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(13-1)^2+(1-10)^2}$

= $\sqrt{144+81}$

= 15 miles

Distance between Drea and Francine = $\sqrt{(16-13)^2+(1-1)^2}$

= 3 miles

Distance between Francine and Beach = $\sqrt{(19-16)^2+(4-1)^2}$

= $\sqrt{9+9}$

≈ 4.2 miles

Total distance between Miya and the beach = 15 + 3 + 4.2

= 22.2 miles

Option (C) is the answer.
