3 0

Answer:

\frac{10}{3}

Step-by-step explanation:

each circle is composed of 3 sectors

The first 3 are completely shaded representing 3 + 3 + 3 = 9 sectors

the last one has 1 sector of 3 shaded representing  1 sector

sectors shaded = 9 + 1 = 10

improper fraction is then \frac{10}{3}

The sum of two numbers is 75. The second number is 3 less than twice the first
Mandarinka [93]

Answer:

\large{\textbf{The two numbers are: 26 and 49}.\\}

Step-by-step explanation:

\large{\textup{assume the two numbers are $x$ and $y$.}}\\\large{\textup{The given sentences are written in mathematical terms as follows:}\\$$ x + y =  75  \hspace{25mm} (1)$$ $$ y = 2x - 3 \hspace{25mm} (2) $$  \\\textup{Substituting $(2)$ in $(1)$,}\\\begin{align*} &  \implies x + 2x - 3 = 75  \\& \implies 3x = 78 \\& \implies x = 26\end{align*}\textup{Substituting $x$ in $(1), \hspace{5mm} y = 49$} }

What is the volume of the figure
Rufina [12.5K]

Answer:

2411.52 cm³

Step-by-step explanation:

V = (2/3)πr³        Use the equation for volume of a hemisphere

V = (2/3)(3.14)(8)³     Simplify the exponent

V = (2/3)(3.14)(512)   Multiply

V = 1071.79 cm³

V = πr² h/3                   Now find the volume of the cone

V = (3.14)(8)²(20/3)      Simplify the exponent

V = (3.14)(64)(20/3)      Multiply

V = 1339.73 cm³

Add both of the volumes together to get the volume of the figure.

1071.79 + 1339.73 = 2411.52 cm³
