Answer:

Option A and D.

Step-by-step explanation:

The scale is given 1 centimeter = 5 kilometers

We have to find the equivalent scales from the given options.

A. 3 cm to 15 km

∵ 1 cm to 5 km

∴ 3 cm to 3 × 5 = 15 km

This option is right.

B. 1 mm to 150 km

∵ 1 mm = 0.1 cm

∴ 0.1 cm = 150 km

This is not the correct option

C 5 Cm to 1 km

∵ 1 cm to 5 km

∴ 5 cm = 5 × 5 = 25 km

This option is incorrect.

D. 5 mm to 2.5 km

1 cm = 10 mm

5 mm = 0.5 cm

∵ 0.5 cm = 2.5 km

∴ 1 cm = 2.5 ÷ 0.5 = 5 km

This is the correct option

E. 1 mm to 500 km

10 mm = 1 cm

1 cm to 5000 km

This is not correct

Therefore, Option A and D is equivalent to the scale.

Find the volume of the garden shed
Leno4ka [110]

Answer:

47.3 m³

Step-by-step explanation:

The garden shed is made up of a rectangular prism and a pyramid.

<h3><u>Volume of a rectangular prism</u></h3>

\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\&=4 \times 4 \times 2\\&=16 \times 2\\&=32\;\; \sf m^3\end{aligned}

<h3><u>Volume of a pyramid</u></h3>

<u />

From inspection of the given diagram, the slant height of the pyramid is 3.5 m.  

Calculate the perpendicular height of the pyramid using Pythagoras Theorem:

\begin{aligned}\implies a^2+b^2&=c^2\\2^2+h^2&=3.5^2\\h^2&=8.25\\h&=\sqrt{8.25}\;\; \sf m\end{aligned}

Therefore:

\begin{aligned}\textsf{Volume of a pyramid}&=\dfrac{\sf length \times width \times height}{3}\\\\&=\dfrac{\sf 4 \times 4 \times \sqrt{8.25}}{3}\\\\& = 15.31883372\;\; \sf m^3\end{aligned}

<h3><u>Volume of the garden shed</u></h3>

\begin{aligned}\implies \textsf{Volume of shed}&=\textsf{Volume of rectangular prism}+\textsf{Volume of pyramid}\\&=32+15.31883372\\& = 47.3\;\; \sf m^3\;(nearest\;tenth)\end{aligned}

A number is three less than six times another numbers. The sum is 53. Find the numbers
Pachacha [2.7K]
X = 6y - 3
x + y = 53

6y - 3 + y = 53
7y - 3 = 53
7y = 53 + 3
7y = 56
y = 56/7
y = 8

x = 6y - 3
x = 6(8) - 3
x = 48 - 3
x = 45

ur numbers are : 8 and 45
