Find the area of ABC<br>Help

Katarina [22]

The value of the scale factor is 3. Then the height and area of the triangle ΔABC will be 9 ft and 54 square ft.

<h3>What is dilation?</h3>

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

The area of the triangle ΔDEF is 6 square ft. And the base length of the triangle ΔDEF is 4 ft.

The area of the triangle is given as

$\rm Area = \dfrac{1}{2} \times bh\\\\$

Then the height of the triangle ΔDEF will be

$\rm 6 = \dfrac{1}{2} \times 4 \times h\\\\h = \dfrac{12}{4}\\\\h = 3$

Then the scale factor will be

$\rm SF = \dfrac{12}{4} = 3$

Then the height of the triangle ΔABC will be

$\rm \dfrac{H}{3} = 3\\\\H \ = 9$

Then the area of the dilated triangle ΔABC will be

$\rm Dilated \ Area = \dfrac{1}{2} \times 12 \times 9\\\\Dilated \ Area = 54 \ ft^2$

More about the dilation link is given below.

If the Probability of an event happening is 70%, what are the ODDS of the event happening?

elena55 [62]

Answer:

a) 7:10

Step-by-step explanation:

An example of this would be having seven blue marbles and three red marbles in a jar. If you randomly select one, the chance of that marble being blue is seventy, because 10 (total number of marbles) divided by seven (number of blue marbles) is 0.70, and if you convert this to a whole number (by multiplying it by 100) you get 70.

According toThe Humane Society in 2009 33% of US households owned at least one cat and 56% of households who did own cats owned

taurus [48]

Answer:

<h2>21.4368 ≅ 21.44 million households owned at least two cats.</h2>

Step-by-step explanation:

Total number of households were 116 million.

Hence, 100% = 116 million.

33% of the total US households owned at least one cat.

Hence, the number of household having at least one cat is $\frac{33\times116}{100} = \frac{3828}{100} = 38.28$ million.
