Give each trig ratio as a fraction in simplest form.

nirvana33 [79]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

sin(D) = 20/29

D = arcsin(20/29)

D=43.60281897 °

cos( 43.60281897 °)= DF / 29

DF = 29*cos( 43.60281897 °)

DF = 21

sin(D) = 20/29

cos(D) = 21/29

tan(D) = 20 / 21

sin(E) = 21/29

cos(E) = 20/29

tan(E) = 21 / 20

$36\%$ of the beans in Pythagoras's soup are lentils, and $33\frac13\%$ of those lentils are green. If Pythagoras removes all th

bulgar [2K]

Question is not proper, Proper question is given below;

36% of the beans in Pythagoras's soup are lentils, and 33 1/3% of those lentils are green.

If Pythagoras removes all green lentils from his soup, then x% of the original beans remain. What is x?

Answer:

88% of the original beans remains $(x)$ after removing green lentils.

Step-by-step explanation:

Given:

Let the Original beans be 'n'.

Now given:

36% of the beans in Pythagoras's soup are lentils.

So we can say that;

Amount of lentils = $\frac{36}{100}n=0.36n$

Also Given:

33 1/3% of those lentils are green

Amount of green lentils = $33\frac{1}{3}\%\ \ Or \ \ \frac{100}{3}\%$

Amount of green lentils = $\frac{100}{3}\times 0.36n\times\frac{1}{100}= 0.12n$

Now we need find the percentage of original beans remain after removing green lentils.

Solution:

percentage of original beans remain ⇒ $x\%$

To percentage of original beans remain after removing green lentils we will subtract Amount of green lentils from Original beans and then multiplied by 100.

framing in equation form we get;

$x\%$ = $(n-0.12n)\times 100=88n \ \ \ Or \ \ \ 88\%$

Hence 88% of the original beans remains $(x)$ after removing green lentils.

dolphi86 [110]

Answer:

<h2>4 students</h2>

Step-by-step explanation:

Step one:

given

we are told that the total number of students is =16

so 25% of these students preferred pizza

Firstly, we want to know what 25% of 16 will be

=25/100*16

=0.25*16

<em>This means that only 4 students preferred pizza</em>

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

Cerrena [4.2K]

Answer:

growth at the rate of 81% increase.

Step-by-step explanation:

When the base of the exponential function (1.81) is greater than one, it is growth, because with x increasing by one, the value increases by 81% (1.81-1.0)

On the other hand, when the base is less than one, then it decrease at the rate of (1-base). For example, when the base is 0.83, then increasing the value of x DECREASES the value by (1-0.83)= 17%.
