The triangles below are similar. What is the length of ? A. 17 cm C. 19 cm B. 18 cm D. 20 cm

denis-greek [22]

Answer:

B. 18 cm.

Step-by-step explanation:

Because they are similar, we can say that segment AC corresponds to segment DF, and segment AB corresponds to segment ED. So, we can set up a proportion.

$\frac{16}{24} =\frac{12}{x}$

$\frac{2}{3} =\frac{12}{x}$

2 * x = 12 * 3

2x = 36

x = 18

So, the length of ED is B. 18 cm.

Hope this helps!

Arielle wants to make a circular garden. She has enough fencing for a garden circumference of 15 feet. There is a 7-foot gap bet

lesantik [10]

Answer:

yes

Step-by-step explanation:

We need to check if the circle with a circumference of 15 feet is smaller then 7 feet. If so it possible.

Formule for circular circumference = pi * diameter, which should be 15.

So pi * d =15

There fore d = 15/pi

d = 4.77464829275686 feet, which is smaller then 7 feet, so it will fit easilly.

C and D are same options

(D) $f(x) = x^2$

Step-by-step explanation:

$f(x) = {x}^{2} \\ plug \: x = - x \\ f( - x) = {( - x)}^{2} = {x}^{2} \\ f( - x) = f(x)$

The value of a house that was purchased 20 years ago has been appreciating by 1.2% each year since it was purchased. If the hous

Kamila [148]

I believe it would have been $347,316.95 at the time of purchase.

1.2% of 456996 is 5483.952

$5483.952 \times 20 = 109679.04$

So:

$456996 - 109679.04 = 347316.95$
