Answer:

<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>

Step-by-step explanation:

<u>Length, Area, and Volume Scale Factors</u>

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is a^2:b^2 and the scale factor of their volumes is a^3:b^3.

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

\sqrt{4}:\sqrt{25}=2:5

The volume scale factor is: 5^3:2^3 = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Thus, after she pours the 15th container, in the middle of the next one, the work will be done

The answer will be <span>Negative

Write sin(</span>\frac{5 \pi }{4}) as sin(\pi+\frac{ \pi } {4}<span>)

Using the summation identity will be:
</span>=sin(\pi)+cos(\pi)sin(\frac{ \pi }{4}<span>)
</span><span>
By following the trivial identity, you should get:
=</span>0*\frac{ \sqrt{2}}{2}+(-1) \frac{\sqrt 2} {2}

<span>Remove the parentheses on -1, then multiply</span>
=0*\frac{ \sqrt 2} {2}-1* \frac{ \sqrt 2} {2}

You should get:
- \frac{ \sqrt 2} {2}

At a sports event, 1, 045 spectators will be
raketka [301]

Answer:

85n >/= 1,045

Step-by-step explanation:

85 people times n buses has to equal or exceed 1,045 people

85n is greater than or equal to 1,045

85n >/= 1, 045

n >/= 12.29

So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)

Please lmk if you have questions.

a rectangle that is 30 inches long and 10 inches wide can be divided into two congruent squares. True or false?
Sever21 [200]

Answer:

False

Step-by-step explanation:

To split the rectangle into 2 parts, you can go one of two ways. One way would make the parts 15" by 10", and the other way would make the two parts 30" by 5". Neither way is equal on all sides, which means neither one is a square. That would make the statement false.
