A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the mi
g100num [7]
legs of the triangles

Each triangle 30-60-90 is:

         one leg: 15 ft => short diagonal = 2 * 15ft = 30ft

         other leg, x:

         tan(30) = 15 / x => x = 15 ft / tan(30) = 25.98 ft

=> long diagonal = 2 * 25.98ft = 51.96 ft

side of the rhoumbus =  hypotenuse of one triangle

side of the rhombus = √ [ (15)^2 + (25.98)^2 ] = √(900) = 30 ft

Area of the rhombus:

4 * area of one triangle = 4 [base*height/2] = 4*15*25.98/2 = 779.43 ft^2

The shortest distance accross the garden is equal to the side of the rhombus = 30 ft

The ratios a: B and B :c are equivalent to one another
Dafna11 [192]

Answer:

Options (2) and (5)

Step-by-step explanation:

Given ratio is a : b and b : c

\frac{a}{b}=\frac{b}{c}

\frac{b}{a}= \frac{c}{b} [Option 2]

\frac{a}{b}=\frac{b}{c}

b × b = a × c

b² = ac

If a = b,

b² = bc

b = c [Option 5]

Therefore, Options (2) and (5) are the correct options.

Match the absolute value expression to its correct distance from zero on the number line.
Kaylis [27]

Answer:

  • 7.1
  • 6.9
  • 5
  • 5.7

Step-by-step explanation:

The value of the expression is its distance from zero. The absolute value is the positive value without any minus sign.

  |-7.1|=7.1\\\\|2.7+4.2|=|6.9|=6.9\\\\|4-9|=|-5|=5\\\\|-3.1+8.8|=|5.7|=5.7
