Answer: 4.7 cm

Step-by-step explanation:

<h3>Because </h3><h3>1.5mm =0.15 cm ,</h3><h3>so both covers together would be 0.3 cm , subtract that from 5 cm,i.e.,</h3><h3>5 -0.3 = 4.7 cma book has two covers one at front and at back</h3><h3 /><h3>so 1.5 +1.5 =3 mm</h3><h3 /><h3>so 10 mm = 1 cm</h3><h3 /><h3>convert 5 cm to mm as 5 * 10 = 50 mm</h3><h3 /><h3>50-3 = 47 mm or 4.7 cm</h3><h3>Have a awesome night✨</h3>

A straight slide in a playground design makes an isosceles triangle with the
julia-pushkina [17]

Answer:

Option D.

Step-by-step explanation:

  • First, the you need ti understand that the triangle is an isosceles right angled triangle. In other words, the base and height are equal in length. The third side is the slide. This is the longest side.
  • Next, we know that the formula for calculating the area of a right angled triangle is given by:

        A = 1/2 (base × perpendicular height)

  • The perpendicular height is equal to the base. Let's say the base is <em>x</em>. It means that the height is also x, since height = base.
  • Therefore, the formula will be:

       A = 1/2 (x.x)

           =1/2 (x²)

      32 = 1/2 (x²)

     Multiplying both sides by 2 gives:

     32×2 = x²

     64  = x²

       8   = x

To find the third side, we use the Pythagoras theorem:

    C² = A² + B²

         = 8² + 8²

         = 128

   C = √128

       = 8√2

However, the answer will not be exact, so we  multiply the length of the base and height by 2. This gives x = 16 (Length of base = length of height)

Repeating the steps above gives C = √ (16)² + (16)²

                                                           = √256

This corresponds to option D.

9. ax + by = (a - b), bx - ay = (a + b)​
mart [117]

Answer: give me brainliest

Step-by-step explanation:

ax+by=a-b

ax=a-b-by

x=a-b-by/a←

bx-ay=a+b

substituting

b(a-b-by/a)-ay=a+b

ab-b²-b²y/a-ay=a+b

ab-b²-b²y-a²y/a=a+b

ab-b²-(b²+a²)y=a²+ab

-(b²+a²)y=a²+ab-ab+b²

(b²+a²)y=-(a²+b²)

y=-(a²+b²)/a²+b²

y=-1←

substituting value of y

x=a-b-b(-1)/a

x=a-b+b/a

x=a/a

x=1

I need help in area it's hard
Fofino [41]
The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>  

        For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>

Area = Length * width  

The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.

= 20 square centimeters
