Answer:

27 cm

Step-by-step explanation:

Hi there!

Let <em>b</em> be equal to the length of the base.

Form a proportion:

\displaystyle \frac{2}{3} =\frac{18}{b}

Cross multiply:

3*18=2b\\54=2b\\b=27

Therefore, the length of the base is 27 cm.

I hope this helps!

&lt;1 and &lt;2 form a linear pair. The measure of &lt;2 is six more than twice the measure of &lt;1. Find the measure of &lt;2
MrMuchimi

Answer:

122 Degrees

Step-by-step explanation:

Since we are given that angle 1 and 2 make a linear pair:

angle 1 + angle 2 = 180 degrees ----------------------------(1)

We have also been told that angle 2 is 6 more than twice the measure of angle 1

Which means: angle 2 = (2*angle1)  + 6 -------------------(2)

From putting the value of angle 2 in (1) from (2)

<em>angle 1 + 2*angle 1 + 6 = 180</em>

<em>3*angle 1 = 174</em>

angle 1 = 58 degrees -----------------------(3)

From (1) and (3):

<em>angle 2 + 58 = 180</em>

angle 2  = 122 degrees

Therefore, the measure of angle 2 is 122 degrees

A family is staying in a hotel for 2 nights. The hotel costs $91.35 a night. About how much will they pay for the hotel?
statuscvo [17]
All we need to do to find the correct answer is to double the prize for a night. I'll "cut" it into pieces so you can see exactly how I calculated it:

$91.35 * 2 =
= $90.00 * 2 + $1.00 * 2 + $0.35 * 2 =
= $180.00 + $2.00 + $0.70 =
= <u>$182.70</u>

Answer: They will pay $182.70 for two nights at the hotel.
