Answer:

1. 26:5 or

$\frac{26}{5}$ or

5.2 as a decimal

2. 21:26 or

$\frac{21}{26}$ or

0.81 as a decimal

3. 21:5 or

$\frac{21}{5}$ or

4.2 as a decimal

4. 5:21 or

$\frac{5}{21}$ or

0.24 as a decimal

Step-by-step explanation:

A ratio is a comparison of two quantities and can be written in several forms including fractions. It is most commonly written in fraction form or a:b.

To write a ratio, we count the number of each quantity we are comparing. A part to whole ratio for letters and vowels would be the part compared to the whole. For example, there are 21 consonants to 26 letters in the alphabet. We write 21:26 or $\frac{21}{26}$ or 0.81. We can also compare the number of vowels which is 5:26 or

A part to part ration compares a part to a part like the number of consonants is 21 with the number of vowels is 5. We write the ratio as consonants : vowels.

21:5 or

$\frac{21}{5}$ or

4.2 as a decimal.

We can reverse and write vowels : consonants.

5:21 or

$\frac{5}{21}$ or

0.24 as a decimal.

A factory packed 9600kg of flour in to small bags and large bags. Each small bag contained 3kg of flour and each large bag conta

yawa3891 [41]

Answer:

696 large bags of flour were packed.

Step-by-step explanation:

Let large bags of flour be 'y'

Let small bags of flour be 'x'. That is x=2040 (according to the question)

$(3 \times x) + (5 \times y) = 9600$

$(3 \times 2040) + ( 5 \times y) = 9600$

$(6120) + (5 \times x) = 9600$

$(5 \times x) = 9600 - 6120$

$(5 \times x) = 3480$

$x = 3480 \div 5$

$x = 696$

If tan ⁡x=12/5, and 0°

Charra [1.4K]

The value of sin(2x) is $\frac{120}{169}$

Explanation:

Given that $tan x =\frac{12}{5}$

The formula for $sin(2x)$ is $\sin (2 x)=2 \sin x \cos x$

Since, $\tan x=\frac{o p p}{a d j}$

Also, it is given that $tan x =\frac{12}{5}$

Thus, $opp=12$ and $adj=5$

To find the hypotenuse, let us use the pythagoras theorem,

$\begin{aligned}h y p &=\sqrt{12^{2}+5^{2}} \\&=\sqrt{144+25} \\&=\sqrt{169} \\&=13\end{aligned}$

Now, we can find the value of sin x and cos x.

$\sin x=\frac{\text { opp }}{h y p}=\frac{12}{13}$

$\cos x=\frac{a d j}{h y p}=\frac{5}{13}$

Now, substituting these values in the formula for sin 2x, we get,

$\begin{aligned}\sin (2 x) &=2 \sin x \cos x \\&=2\left(\frac{12}{13}\right)\left(\frac{5}{13}\right) \\&=\frac{120}{169}\end{aligned}$

Thus, the value of sin(2x) is $\frac{120}{169}$

salantis [7]

Answer:

( 41° * π * radius) / 180

Step-by-step explanation:

The arc measure of major arc ABC on circle P is

( 41° * π * radius) / 180 degrees.

For instance if P = 5 then see the picture, the Arc Length = 3.58

Which parabola has the graph shown?

ryzh [129]

The vertex is (-1, 2).

The equation of parabola:

$x=(x-k)^2+h$ where (h, k) is the vertex

We have h = -1 and k = 2.

Substitute:

$x=(y-2)^2-1\ \ \ \ |+1\\\\(x+1)=(y-2)^2$
