Answer:

$2(2a - 3) - 3(4a + 5) \\ = 2 \times 2a - 2 \times 3 - (3 \times 4a + 3 \times 5) \\ = 4a - 6 - (12a + 15) \\ = 4a - 6 - 12a - 15 \\ = - 8a - 21 \\ thank \: you$

Step-by-step explanation:

2(2a-3)-3(4a+5)

=4a-6-12a-15

=4a-21-12a

= -8a-21

A two-dimensional vector has an x-component of 10.3~\text{meters}10.3 meters and a y-component of 4.30~\text{meters}4.30 meters.

Answer:

23°

Step-by-step explanation:

The angle a vector makes relative to the +x axis is found as ...

α = arctan(y/x) = arctan(4.30/10.3) ≈ 22.66°

The angle is about 23°.

Additional comment

This vector resides in the first quadrant, so no adjustment of the angle is needed. In other quadrants, 180° may need to be added or subtracted from the angle given by the arctan function to arrive at the correct value. (Some calculators and spreadsheets have an ATAN2(x, y) function that takes signs into account.)

James sold 450 tickets for the community play. Tickets for children cost $2, and tickets for adults cost $5. James sold $1,800 w

nlexa [21]

Answer:

James sold 300 tickets for adults

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of tickets sold by James = 450

Cost of a child ticket = $ 2

Cost of an adult ticket =$ 5

Amount of money collected by James after selling the 450 tickets for the community play = $ 1,800

2. How many tickets for adults did James sell?

x = Number of adult tickets James sold

450 - x = Number of children tickets James sold

For solving for x, we write this equation:

5x + 2 * (450 - x) = 1,800

5x + 900 - 2x = 1,800

3x = 1,800 - 900

3x = 900

x = 900/3 = 300

450 - x = 450 - 300 = 150

James sold 300 tickets for adults and 150 for children

Crane Company provided the following information from its accounting records for 2019.

Ipatiy [6.2K]

Answer:

$10.00 per hour

Step-by-step explanation:

Overhead application rate which is also known as overhead absorption rate on the basis on labor hours is the total budgeted overhead for 2019 which is $900,000 divided by the expected production of 90,000 labor hours for the year.

overhead application rate=$900,000/90,000=$10 per hour

This implies that for every one hour worked overhead cost of $10 would be added to the other costs incurred.

The correct option then is the third option of $10.00 per hour

The perimeter of a square garden is (20k+36) feet. Write an expression

sertanlavr [38]

Answer:

5k+9

Step-by-step explanation:

Since it's a square, all four sides are equal so divide the equation of the total by 4.

20k/4=5k

36/4=9

The length of one side of the garden can be represented by the expression:

5k+9
