What percent of 80 is 12?what number is 75% of 52? ​

Mathematics
1 answer:
HACTEHA [7]3 years ago
5 0

Answer:

<em>The answer for the first question is: </em>

<em>12/80 =</em>

<em>12 ÷ 80 =</em>

<em>0.15 =</em>

<em>0.15 × 100/100 =</em>

<em>0.15 × 100% =</em>

<em>(0.15 × 100)% =</em>

<h2><em>15%</em></h2>

<em>Then, the answer for the second question is: </em>

<em>75% × 52 =</em>

<em>(75 ÷ 100) × 52 =</em>

<em>(75 × 52) ÷ 100 =</em>

<em>3,900 ÷ 100 =</em>

<h2><em>39 </em></h2>

2m - 6 = 8m then 3m =
Vinil7 [7]

Answer:

3m = -3

Step-by-step explanation:

You are given

2m - 6 = 8m,

hence,

2m - 8m = 6,

-6m = 6,

m = 6%2F%28-6%29,

m = -1.

Therefore, 3m = -3.

What the correct answer do not want the wrong answer please
Crank

Answer:

388.5yd²

Step-by-step explanation:

We have Triangle TUV

In the question, we are given already

Angle U = 32°

Angle T = 38°

Angle V = ???

Side t = 31yd

Side u = ?

Side v = ?

Area of the triangle= ?

Step 1

We find the third angle = Angle V

Sum of angles in a triangle = 180°

Third angle = Angle V = 180° - (32 + 38)°

= 180° - 70°

Angle V = 110°

Step 2

Find the sides u and v

We find these sides using the sine rule

Sine rule or Rule of Sines =

a/ sin A = b/ Sin B

Hence for triangle TUV

t/ sin T = u/ sin U = v/ sin V

We have the following values

Angle T = 38°

Angle U = 32°

Angle V = 110°

We are given side t = 31y

Finding side u

u/ sin U= t/ sin T

u/sin 32 = 31/sin 38

Cross Multiply

sin 32 × 31 = u × sin 38

u = sin 32 × 31/sin 38

u = 26.68268yd

u = 26.68yd

Finding side x

v / sin V= t/ sin T

v/ sin 110 = 31/sin 38

Cross Multiply

sin 110 × 31 = v × sin 38

v = sin 110 × 31/sin 38

v = 47.31573yd

v = 47.32yd

To find the area of triangle TUV

We use heron formula

= √s(s - t) (s - u) (s - v)

Where S = t + u + v/ 2

s = (31 + 26.68 + 47.32)/2

s = 52.5

Area of the triangle = √52.5× (52.5 - 31) × (52.5 - 26.68 ) × (52.5 - 47.32)

Area of the triangle = √150967.6032

Area of the triangle = 388.5454973359yd²

Approximately to the nearest tenth =388.5yd²

Identify the Asymptotes for the graphs below help pls!
scoray [572]
Asymptotes are lines that continues to approach a given curve but never actually meets it! For the second figure it is the Y axis since the curves slowly appear to approach the Y axis! Not sure about the first figure(probably the X axis)!
