find the perimeter and area of a square whose side measures 1) 3.5 2)1m 20cm no stealing point pls its an emergency​
Alborosie
For 1.
Solution,
Sides(l)= 3.5
Now,
Perimeter of square=4l
=4*3.5
=14
Then,
Area of square =l^2
=3.5*3.5
=12.25
For 2.
Solution,
Sides(l)=1
Now, perimeter of square =4l
=4*1
=4
Then,
Area of square =l^2
=1*1
=1
For 3.
Solution,
Sides(l)= 20
Now,
Perimeter of square=4l
=4*20
=80
Then,
Area of square =l^2
=20*20
=400

Please help me
____ [38]
This is pretty weird: ax+ b > c is equivalent to ax + b > 0, for instance. c might always be chosen as zero, or b, or any value!

280x <= 348.76, or -280x + 348.76 >= 0,

so a = -280, b = 348.76 and c = 0 is one solution

Answer:

  • sin(X) = 6/7.5
  • XY = 4.5
  • cos(X) = 4.5/7.5
  • tan(X) = 6/4.5

Step-by-step explanation:

It is convenient to use the Pythagorean theorem to find XY to start with. That theorem tells you ...

  XZ² = YZ² + XY²

Solving for XY, you find ...

  XY² = XZ² - YZ²

  XY = √(XZ² - YZ²) = √(7.5² -6²) = √(56.25 -36) = √20.25

  XY = 4.5

The mnemonic SOH CAH TOA is very helpful here. It reminds you that ...

  Sin = Opposite/Hypotenuse

  sin(X) = 6/7.5

  Cos = Adjacent/Hypotenuse

  cos(X) = 4.5/7.5

  Tan = Opposite/Adjacent

  tan(X) = 6/4.5

_____

<em>Comment on the triangle and ratios</em>

The side lengths of this triangle are in the ratios ...

  XY : YZ : XZ = 3 : 4 : 5

If you recognize that the given sides are in the ratio 4 : 5, this tells you that you have a "3-4-5" right triangle with a scale factor of 1.5. At least, you can find XY = 1.5·3 = 4.5 with no further trouble.

The trig ratios could be reduced to sin(X) = 4/5; cos(X) = 3/5; tan(X) = 4/3, but the wording "don't simplify" suggests you want the numbers shown on the diagram, not their reduced ratios.

Can there be more than one mean or mode in a math problem??
astraxan [27]

Math. When no number occurs more than once in a data set, there is no mode. If each of two numbers occurs twice, we say the set is bimodal.
