1 m = 100 cm

1 book = 2cm wide.

Number of books = 100 ÷ 2 = 50 books.

Answer: 50 books can fit on the shelf.

A cell phone company has a basic monthly plan of $40 plus $0.45 for any minutes used over 700. Before receiving his statement, J

Serga [27]

Ok so we know he used over 700 because he was charged more than 40. Then we take the $8.10 and divide 0.45 into it. This then gives you 18 more minutes. Then add 18 to 700 and you get 718 min.

Which expression is eq to (125^2/125^4/3)

sweet [91]

Answer:

25

Step-by-step explanation:

So the denominator can be simplified to 5⁴ → $(5^3)^\frac{4}{3}$ and then the 3's cancel out and we are left with 5⁴

Now our new fraction is $\frac{125^{2} }{5^{4} } = \frac{15625}{625}$ which then simplifies to 25

Which of the following best completes the proof showing that ΔWXZ ~ ΔXYZ?

skelet666 [1.2K]

Angles formed by the segment $\overline{XZ}$ in the triangles ΔWXZ, and ΔXYZ, are equal and the given corresponding sides are proportional.

The option that best completes the proof showing that ΔWXZ ~ ΔXYZ is; <u>16 over 12 equals 12 over 9</u>

Reasons:

The proof showing that ΔWXZ ~ ΔXYZ is presented as follows;

Segment $\overline{XZ}$ is perpendicular to segment $\overline{WY}$

∠WZX and ∠XZY are right angles by definition of $\overline{XZ}$ perpendicular to $\overline{WY}$

∠WZX in ΔWXZ = ∠XZY in ΔXYZ = 90° (definition)

$\displaystyle \frac{WZ}{XZ} = \frac{16}{12} = \mathbf{ \frac{4}{3}}$

$\displaystyle \mathbf{ \frac{XZ}{ZY}} = \frac{12}{9} = \frac{4}{3}$

Therefore;

$\displaystyle \frac{16}{12} = \frac{12}{9}$ , which gives, $\displaystyle \mathbf{\frac{WZ}{XZ} }= \frac{XZ}{ZY}$

Given that two sides of ΔWXZ are proportional to two sides of ΔXYZ, and

that the included angles between the two sides, ∠WZX and ∠XZY are

congruent, the two triangles, ΔWXZ and ΔXYZ are similar by Side-Angle-

Side, SAS, similarity postulate.

The option that best completes the proof is therefore;

$\displaystyle \frac{16}{12} = \frac{12}{9}$ which is; <u>16 over 12 equals 12 over 9</u>

Please help!!!!!!!!!! !!

Answer:

$The ~length~ is ~9.6~ units$ ✔︎

༄❁༄❁༄❁༄❁༄

$a=8\\b=2\\c=?\\d=?\\e=5$

$Using~ Pythagorean ~theorem:$

$c^2=a^2+b^2$

$c^2=(8)^2+(2)^2$

$\sqrt{c^2} =\sqrt{68}$

$c=\sqrt{68} ~or~2\sqrt{17}$

»»---------------------►

$d^2=c^2+e^2$

$d^2=(2\sqrt{17})^2+(5)^2$

$d^2=68+25$

$\sqrt{d^2} =\sqrt{93}$

$d=\sqrt{93} ~or~9.6$

$So, your~ answer ~is ~9.6$
