Answer 1

Answer:

  4. 11/6, 121/36

  5. 5/8, 25/64

  6. 4/7, 16/49

  7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

  perimeter ratio = red leg/blue leg

The area ratio is the square of that:

  area ratio = (perimeter ratio)²

__

4.

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

__

5.

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

__

6.

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

__

7.

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81

How many solutions exist for the given equation?3x + 13 = 3(x + 6) + 1

Answers

Answer:

0

Step-by-step explanation:

3x+13=3(x+6)+1
Expand:

3x+13=3x+18+1
Simplify:

3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:

3x=3x+6

Subtract 3x from both sides:
3x-3x=3x-3x+6

0=6

Since the sides are not equal there are no solutions to this problem

How to factorize a quadratic polynomial with single variable?

Quadratic polynomial with single variables are expressible in the form

[tex]ax^2 + bx + c[/tex]

where x is the variable and a,b,c are constants.

Its factored form is

[tex]\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})[/tex]

For the given case, the expression given to us is [tex]x^2 - x - 6[/tex]

Comparing it with the standard form of quadratic expression  [tex]ax^2 + bx + c[/tex], we get: a = 1. b = -1. and c = -6

Using the aforesaid formula, we get:

[tex]=\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})\\\\=\dfrac{1}{4}\times(2x -1 - \sqrt{1 +24})(2a -1 + \sqrt{1 + 24})\\\\=\dfrac{1}{4} \times (2x - 1-5)(2x - 1 + 5)\\\\=(x -3)(x+2)[/tex]

What is a cuboid?

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A box that has a volume of 729 inches.

First we'll prime factorize 729.

729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.

If we take the cube root of 729 it would be 3×3 = 9.

So, It is a cube with a side length 9.

Now, We know area of a cube is side².

Therefore, The area of this cube is 9² = 81 in².

one and one fifth cups
three and one fourth cups
seven and two fourths cups

So if one batch needs 3/4 of a cup and she needs to make 10 batches then you multiply how many batches by how many water cups required for one batch:

3/4 • 10 = 30/4 = 7 2/4

So she needs seven and two fourths cups of water.

Answer:

3/4 • 10 = 30/4 = 7 2/4

Answers

Answer:

if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.

therefore m∠3 = 30°

extra's:

→ m∠2 = m∠4 =

→ (360-30*20)/2

→ 150°

...............................

See here

m<1 and m<3 are opposite angles to eachother.

And we know that opposite angles are equal

so

m<1=m<3 m<3=30°
