Answer:

6 adults

Step-by-step explanation:

Let

x -----> the number of children

y ----> the number of adults

we know that

The ratio

$\frac{x}{y}=\frac{20}{15}$

using proportion

Find the value of y for x=(20-12)=8

$\frac{20}{15}=\frac{8}{y}\\\\y=15*8/20\\\\y=6$

therefore

6 adults

Which measurement could create more than one triangle A triangle with sides measuring 20 cm, 9 cm, and 10 cm A triangle with sid

Karolina [17]

Answer:

(D)A right triangle with acute angles measuring 45° and 45°

Step-by-step explanation:

The triangles created by the measurements in Options A, B and C have specified lengths of the sides. Therefore, not more than one triangle can be created.

However, for a triangle with acute angles measuring 45° and 45°, an uncountable number of similar triangles (triangles with same shape but different sizes) can be created.

<u>The correct option is D.</u>

El Generico public high school got a new flagpole. But they completely forgot to buy a cord and NO ONE knows how tall the flagpo

lord [1]

According to the rule of similar polygons the ratio of corresponding sides of two polygons will be the same. So in this case the ratio of original length and shadow of a stick and ratio of length of flagpole and its shadow will be the same.

Length of Stick = 5 feet
Shadow of Stick = 8 feet
Shadow of flagpole = 32 feet
Length of flagpole = x = ?

Using rule of similar polygon we can write,

$\frac{5}{8}= \frac{x}{32} \\ \\ \frac{5}{8}*32=x \\ \\ x=20$

Therefore, the length of flagpole will be 20 feet.
