Write -0.37 as a quotient of integers to show that it is rational

Zina [86]

Answer:

-37/100

Step-by-step explanation:

Here, we want to write -0.37 as a quotient of integers

What we are saying is that we want to write it as a fraction of two numbers

That would be;

-0.37 = -37/100

two ships leave a port at the same time. the first ship sails on a bearing of 55° at 12 knots (natural miles per hour) and the s

Korvikt [17]

Answer:

37.59 nautical miles

Explanation:

Distance = Speed x Time

The speed of the first ship = 12 knots

Thus, the distance covered after 1.5 hours

$\begin{gathered} =12\times1.5 \\ =18\text{ miles} \end{gathered}$

The speed of the second ship = 22 knots

Thus, the distance covered after 1.5 hours

$\begin{gathered} =22\times1.5 \\ =33\text{ miles} \end{gathered}$

The diagram representing the ship's path is drawn and attached below:

The angle at port = 90 degrees.

The triangle is a right triangle.

Using Pythagorean Theorem:

$\begin{gathered} c^2=a^2+b^2 \\ c^2=18^2+33^2 \\ c^2=324+1089 \\ c^2=1413 \\ c=\sqrt[]{1413} \\ c=37.59\text{ miles} \end{gathered}$

The two ships are 37.59 nautical miles apart after 1.5 hours.

The trailer ramp is shaped like a triangle prism . The height of the ramp is 14 inches and the volume of the ramp is 4704 inches

Hatshy [7]

Answer:

A = 2167.73 cm²

Step-by-step explanation:

Given that,

A trailer ramp is in the shape of a triangular prism.

the height of the ramp, h = 14 inches

The volume of the ramp, V = 4704 inches²

We need to find the area of the base of the trailer ramp.

The volume of the triangular prism is given by :

$V=A\times h$

A is area of base and h is height

$A=\dfrac{V}{h}\\\\A=\dfrac{4704}{14}\\\\A=336\ \text{inches}^2$

A = 2167.73 cm²

So, the area of the base of the ramp is 2167.73 cm².

A, B and C lie on a straight line segment.A, E and D lie on a straight line segment.BE = 1.8m, CD = 9m and BC = 1.7m.Work out th

katrin2010 [14]

The relationship between the points is an illustration of similar shapes.

The length of AB is 0.43

The given parameters are:

$\mathbf{BE = 1.8}$

$\mathbf{CD = 9}$

$\mathbf{BC = 1.7}$

From the question (see attachment), we have the following observations:

BE corresponds to CD
AB corresponds to AC

So, the equivalent ratio is:

$\mathbf{AB:BE =AC:CD }$

Substitute known values

$\mathbf{AB:1.8 =AC:9 }$

Express as fractions

$\mathbf{\frac{AB}{1.8} =\frac{AC}{9} }$

Multiply both sides by 1.8

$\mathbf{AB =\frac{AC}{5} }$

So, we have:

$\mathbf{AB =\frac{AB + BC}{5} }$

Substitute 1.7 for BC

$\mathbf{AB =\frac{AB + 1.7}{5} }$

Multiply through by 5

$\mathbf{5AB =AB + 1.7}$

Collect like terms

$\mathbf{5AB -AB =1.7}$

$\mathbf{4AB =1.7}$

Divide both sides by 4

$\mathbf{AB=0.425}$

Approximate

$\mathbf{AB=0.43}$

Hence, the length of AB is 0.43
