Answer:

$15\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and the corresponding angles are congruent

In this problem Triangles PQT and RQS are similar by AA Similarity Theorem (The three angles are congruent)

therefore

$\frac{12}{16}=\frac{x}{20}\\ \\x=12*20/16\\ \\x=15\ units$

I need this immediately!! Put the equation in standard form with a positive X coefficient. Y + 6 = 3/2 ( x - 4 ) HELP!!

Readme [11.4K]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given

y + 6 = $\frac{3}{2}$ (x - 4)

Multiply through by 2 to eliminate the fraction

2y + 12 = 3(x - 4) ← distribute

2y + 12 = 3x - 12 ( subtract 2y from both sides )

12 = 3x - 2y - 12 ( add 12 to both sides )

24 = 3x - 2y, that is

3x - 2y = 24 ← in standard form

A Jerome's rock band recorded 13 songs during an afternoon recording session. Each song took 1/6 of a side of a tape to record.

Lapatulllka [165]

Answer:
number of tape sides = 2.1667 tape sides

Explanation:
We know that each song took 1/6 of a side of tape to be recorded.
To know how many tape sides were used to record 13 songs, all we have to do is cross multiplication as follows:
1 song ..................> 1/6 of a tape side
13 songs ..............> ?? tape sides

Number of tape sides = [(13) * (1/6)] / 1
number of tape sides = 2.1667 tape sides

Hope this helps :)

Answer: d) 0.9693

<u>Step-by-step explanation:</u>

refer to the z-table attached.

The table shows the percent from the MEAN. The percent below the mean is 50% so that needs to be added to the value in the table.

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).

The value is 0.4693 --> add 0.5 to that value to get 0.9693.
