Strongly recommend to keep up with Digram , as name of sides are based according to Digram.

As we know soccer feild is rectangle , therefore ∠A = ∠B = ∠C = ∠D = 90°

Now as we have to just find value of diagonal AD therefore just focus on triangle ACD.

we know ∠C = 90° , triangle ACD. is a right angled triangle.

The expanded form of the expressions are -56w^2 + 25w - 49, 2t^2-9t-1 and x/5 + 3/20

Given the following expressions as shown

7(-8w^2+5w-7)
Expanded the expression to have:

7(-8w^2) + 7(5w) -7(7)

-56w^2 + 25w - 49

For the expression -(-2t^2+9t+1), multiply the expression through bu the minus sign to have 2t^2-9t-1

For the expression 3/5(1/3x+1/algebras)

Expand the expression to have:

3/5(1/3x) + 3/5(1/4)

x/5 + 3/20

Hence the expanded form of the expressions are -56w^2 + 25w - 49, 2t^2-9t-1 and x/5 + 3/20

Answer:

Step-by-step explanation:

Restate the problem:

 "  29% of x is $28.9 million"

   (29/100)x = $28.9 million  

          [in word (story) problems "of" usually means multiply]

          29% may be written as (29/100) or 0.29 as needed by the problem.

   x = (100/29)($28.9 million)

   x ≅  $99.655 million

   x ≅ $100 million         [rounded

The correct answer to your question is D

The triangles ΔDJY and ΔFJS are similar triangles. Then the value of x will be 75. Then the correct option is D.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The angle ∠J is common for both triangles.

The triangles ΔDJY and ΔFJS are similar triangles, then we have

DJ/DF = YJ/YS

 50/x = 42/63

       x = 75

Answer:

Change the mixed numbers into an improper fraction:

[tex]2\frac16 \div 2\frac12=\dfrac{2 \times 6+1}{6}\div \dfrac{2 \times 2+1}{2}=\dfrac{13}{6}\div \dfrac{5}{2}[/tex]

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. (Reciprocal is when you swap the numerator and denominator).  Therefore,

[tex]\dfrac{13}{6}\div \dfrac{5}{2}=\dfrac{13}{6}\times\dfrac{2}{5}[/tex]

Now we simply multiply the numerators and the denominators:

[tex]\dfrac{13}{6}\times\dfrac{2}{5}=\dfrac{13 \times 2}{6\times 5}=\dfrac{26}{30}[/tex]

We can now reduce the fraction to its simplest form by dividing the numerator and denominator by 2:

[tex]\dfrac{26}{30}=\dfrac{26\div 2}{30 \div 2}=\dfrac{13}{15}[/tex]

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

I'll assume it is [tex]\frac{21}{6}[/tex]÷[tex]\frac{21}{2}[/tex]

Not so sure if it is that or in mixed form

The division sign will become multiplication sign when two becomes the numerator and 21 becomes the denominator

[tex]\frac{21}{6}[/tex]×[tex]\frac{2}{21}[/tex]

21 will cancel out leaving [tex]\frac{2}{6}[/tex]

Step-by-step explanation:

First, find the circumference of the whole circle.

C=2pir

C=2(3.14)(17)

C=106.76

Then, divide by 2 because a semi-circle is half of a circle.

106.76/2 = 53.38

Therefore, the circumference, or the perimeter, of the semicircle is 53.38

Answer:

Formulae used:

Area of a rectangle = width × length

Area of a triangle = 1/2 × base × height

Area of blue shape:

Area of rectangle + area of triangle

= (9 × 15) + (1/2 × (15 - 9) × 15)

= 135 + (1/2 × 6 × 15)

= 135 + 45

= 180 mm²

Area of yellow shape:

area of rectangle AHPB + area of rectangle GFQP + area of rectangle EDCQ

= (4 × 12) + (6 × (12 - 9)) + (4 × 12)

= 48 + (6 × 3) + 48

= 48 + 18 + 48

= 114 m²

then solve

3x = 6 - 15

3x = -9

x = -3

Answer:

No solution

Step-by-step explanation:

By bisector theorem: the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle

y/8 = 8/2

y = 32 .... sum of the length of 2 sides of triangle must be larger than the 3rd side, 8+2+8 = 18 < 32

y can only has a value < 18

If we use Law of Sines also get y = 32 ... not forming a triangle

The perimeter of the enlarged playground is 24.36 meters, and the increase in area is 16.9 m²

An area is the amount of space occupied by a two dimensional shape or object. The area of a rectangle is:

Area = length * width

Given that length = 5.5 m, width = 3.2 m

Hence:

Area = 5.5 * 3.2 = 17.6 m²

Perimeter = 2(length + width) = 2(5.5 + 3.2) = 17.4 m

There is an increase in both the length and the width of the playground by 40% each. Hence:

New length = 1.4 * 5.5 = 7.7 m, new width = 1.4 * 3.2 = 4.48 m

Area = 7.7 * 4.48 = 34.5 m²

Perimeter = 2(length + width) = 2(7.7 + 4.48) = 24.36 m

Increase in area = 34.5 m² - 17.6 m² = 16.9 m²

The perimeter of the enlarged playground is 24.36 meters, and the increase in area is 16.9 m²
