Step-by-step explanation:

2500 \:  {mm}^{2}  \\  \\=2500\: 1\: mm\times 1\: mm\\=2500\times\frac{1} {1000}\:m \times \frac{1} {1000}\:m\\=2500\times\frac{1} {1000\times 1000}\:m^2 \\=2500\times\frac{1} {1000000}\:m^2 \\=2500\times\frac{1} {10^6}\:m^2\\= 2500 \:  \times 10^{-6}\: m^2 \\    = 0.0025 \:  {m}^{2}  \\  \\  \bigg( \because1 \: mm =  \frac{1}{1000}  \: m \bigg)

Given right triangle ABC. To the nearest degree, find the measure of angle B.
DedPeter [7]

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse.  We will use trig here to solve for angle B.  The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

sin(B)= \frac{ 4.8}{ 5.1} so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators.  This will give us the missing angle value.  Press 2nd then sin and you will see on your screen:

sin^{-1 (

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

the sum of three number is 202, the second is three more than the first number, the third number is three times the second numbe
sertanlavr [38]

Answer:

x = 38

y = 41

z = 123

Step-by-step explanation:

x + y + z = =202

y = x + 3

z = 3y = 3(x + 3) = 3x + 9

<u>x</u> + <u>y</u> + <u>z</u> = <u>x</u> + <u>x + 3</u> + <u>3x + 9</u> = 5x + 12 = 202

5x + 12 = 202

5x = 190

x = 38

y = x + 3 = 41

z = 3y = 123

Two squares have sides 12cm and 4cm respectively. What is the ratio of their sides​
Nookie1986 [14]

Answer:

3 : 1

Step-by-step explanation:

We have to compare the value of two sides.

Ratio of sides = 12 : 4 = \dfrac{12}{4}=\dfrac{4*3}{4*1}=\dfrac{3}{1}

                       =  3 : 1
