Let's convert this fraction to an equal fraction which holds a denominator of 100, since it is a power of 10.

Since the denominator can be multiplied by 5 to achieve 100, we can multiply the entire fraction by 5 to create an equivalent fraction that has a denominator of 100:
17/20 = (17*5)/(20*5) = 85/100

To obtain a decimal from this fraction, take the numerator and move its decimal one place to the left for every 0 in the denominator. Since our denominator has two zeros, we will need to move the decimal place on the 85 two places to the left.

This gives us an answer of .85, which can also be expressed as 0.85.

3.8:(4c+3)=2:2 2/19<br><br>Please help me! I really appreciate it!

Sati [7]

Please note that in such questions, the ":" stands for ratio which in turn stands for divide. Thus, the given expression which is:

$3.8:(4c+3)=2:2\frac{2}{19}$ will become:

$\frac{3.8}{4c+3}= \frac{2}{2\frac{2}{19}}$ .....(Equation 1)

Now, we know that 3.8 can be rewritten as $\frac{38}{10}$ . Also, we know that the mixed fraction $2\frac{2}{19}$ can be re-written as:

$2\frac{2}{19}=2+ \frac{2}{19}= \frac{38+2}{19}= \frac{40}{19}$

Using the above two expressions in (Equation 1) we get:

$\frac{\frac{38}{10}}{4c+3}= \frac{2}{\frac{40}{19}}$

$\frac{\frac{38}{10}} {4c+3}= \frac{2\times 19}{40}= \frac{38}{40}$

Cross-multiplication gives:

$38(4c+3)=\frac{40\times 38}{10}$

$4c+3=4$ $4c=1$

$c=\frac{1}{4}$

Or c=0.25

Thus, we may write the value of c as either the decimal 0.25 or the fraction $\frac{1}{4}$ .

Please urgent fast thanks

Answer:

A) I = $171.73

B) $4771.73

Step-by-step explanation:

We are told her loan is $4600 for 7 months.

Thus;

Principal; P = 4600

Time; T = 7 months = 7/12 year

Interest rate is given as 6.4%

Thus; r = 6.4

A) To get the interest, the Formula is;

I = PRT/100

I = (4600 × 6.4 × (7/12))/100

I = $171.73

B) Since interest is $171.73, it means amount she owes after the 7 months = $4600 + $171.73 = $4771.73

A 20 ft flag pole casts a shadow 32 ft long. What is the angle of elevation of the sun?

Nookie1986 [14]

Answer:

<em>The angle of elevation of the sun is 32°</em>

Step-by-step explanation:

<u>Right Triangles</u>

The flagpole and the ground form a right angle (90°). In triangles with right angles, the trigonometric ratios are satisfied.

Each acute angle has an adjacent leg and an opposite leg. The tangent ratio relates to both legs.

$\displaystyle \tan x=\frac{\text{opposite leg}}{\text{adjacent leg}}$

The opposite leg to angle x is 20 ft and the adjacent leg is 32 ft, thus:

$\displaystyle \tan x=\frac{20}{32}=0.625$

Calculate x by using the inverse tangent:

$x=\arctan 0.625$

$x=32^\circ$

The angle of elevation of the sun is 32°
