Answer: 1584

Step-by-step explanation:

what I done was 132 x 12 which equals 1584 then you will divide 1584 by 132 which equals 12%

Answer:

The number is 1100

Step-by-step explanation:

how I did it was

let the number be represented by x

132/x = 12/100

solve for x by crossing multiply

∴ 132 × 100 = 12x

13200 = 12x

divide both sides by 12

13200/12 = 12x/12

x = 1100

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.

242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51 1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10. 72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.

A triangle has an area of 9m2 and a base of 6m. how do I find the height of this triangle?

KonstantinChe [14]

You know the triangle has a base of 6 meters, and that the formula to find the area of a triangle is 1/2bh or one-half of the base times the height. So, you would plug in 9 meters squared=one half of six times h, or 9m^2=1/2(6)*(h). In simplifying this, you would get 3h=9m^2. Divide both sides by three and get h=3. Hope this helps, and if you need any further explanations, please let me know!

Consider a triangle with two sides that

AURORKA [14]

9514 1404 393

Answer:

C) 14 cm

Step-by-step explanation:

A triangle solver can quickly show you the third side is 14 cm.

The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...

c² = a² +b² -2ab·cos(C)

c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74

c ≈ √196.74 ≈ 14.03

The length of the third side is about 14 cm.

an engineer decides to use similar triangles to find the distance across the river she makes the diagram below which triangles t

sergiy2304 [10]

<h2>Explanation:</h2><h2 />

The missing diagram is shown below. Remember that shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. So this means you can make the object bigger or smaller. So in this case, we know that ΔABC is similar to ΔDEF. If so, we can establish the following proportion:

$\frac{h}{56.7}=\frac{17.2}{52.4} \\ \\ h=56.7\times \frac{17.2}{52.4} \\ \\ h=18.61m$

Our goal is to find x. So by Pythagorean theorem:

$x=\sqrt{17.2^2+18.61^2} \\ \\ \boxed{x=25.34m}$

Conclusion:

<em>Distance across the river is 25.34m </em>
