Answer:

16

Step-by-step explanation:

Triangles XWY and ZWY are congruent because of AAS . the two 90 degree angles are congruent,∠xwy and ∠zwy are congruent because ∠xwz is being bisected, and wy is congruent with wy beacuse of the reflexive property. Since the two triangles are congruent zy must ve congruent to xy because of CPCTC. Since the two linew are congruent and xy=16, zy must also equal 16.

The diameter of the attic is 18ft and its height is 18ft. What's is the volume of the space in the attic
Svet_ta [14]
I attached an image with the complete question.

Answer:
volume of attic = 1526.04 ft³

Explanation:
Volume of cone can be calculated using the following rule:
Volume = \frac{1}{3} * area of base * height
Volume = \frac{1}{3} * π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft

Substitute in the equation to get the volume as follows:
Volume = \frac{1}{3} * 3.14 * (9)^2 * (18) = 1526.04 ft³

Hope this helps :)

Write 5^3 x √5 as a single power of 5
MakcuM [25]
√5 = 5^(1/2)

Multiplying two number with the same base has as result a number with the same base and the sum of the exponents so:

1/2 + 3 = 7/2
which means
5^3 x 5^(1/2) = 5^(7/2)
