Which of the two solids below are similar ?

Pachacha [2.7K]

Answer: I and II.

Step-by-step explanation:

By definition, two solids are similar if their corresponding sides are in the same ratio.

Knowing this, let's find which solids are similar:

Corresponding sides ratio of solids I and II:

$\frac{3}{2}=\frac{2}{\frac{4}{3}}=\frac{5}{\frac{10}{3}}$

$\frac{3}{2}=\frac{3}{2}=\frac{3}{2}$

Corresponding sides ratio of solids I and III:

$\frac{3}{\frac{9}{2}}=\frac{2}{3}=\frac{5}{8}$

$\frac{2}{3}=\frac{2}{3}=\frac{5}{8}$

Corresponding sides ratio of solids II and III:

$\frac{2}{\frac{9}{2}}=\frac{\frac{4}{3}}{3}}=\frac{\frac{10}{3}}{8}}$

$\frac{4}{9}=\frac{4}{9}=\frac{5}{12}$

You can observe that the solids I and II are similar.

(b) If the sum of two consecutive odd numbers is 48, find the numbers.

Rudiy27

Answer:

23, 25

Step-by-step explanation:

let the first number be represented as A, since there are two odd numbers, the second number would be A + 2

A + A+2 = 48

2A + 2 = 48

2A = 48 - 2

2A = 46 ( divide both sides by 2)

A = 23

since we know the next number to be A + 2

= 23 + 2 = 25

the two numbers are 23 and 25

What is the area of △ABC ? Enter your answer, as a decimal, in the box. Round only your final answer to the nearest tenth. units

fiasKO [112]

Answer: $36.1\ units^2$

Step-by-step explanation:

You need to use the SAS area formula. This is:

$A=\frac{a*b*sin(\alpha)}{2}$

Given the triangle ABC, you know that:

$a=AC=10\ units\\b=BC=17\ units\\\alpha=\angle ABC=25.1\°$

Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:

$A=\frac{(10\ units)(17\ units)*sin(25.1\°)}{2}\\\\A=36.1\ units^2$

The area of a square region is 196yd ^2. what is the length of one side of the region?

Bas_tet [7]

It will probably be 196yd because the formulae to calculate the area of a square is any side^2 as a square has all equal sides and area = length times breath. Hope this is helpful.
