Y = 32.25 x + 40
If it takes 6 hours to repair a car:
y = 32.25 * 6 + 40 = 193.5 + 40 = $233.50
The closest are $251.50 and $211.50.
$251.50 - $233.50 = $18
$233.50 - $211.50 = $22
$18 < $22
Answer:
The closest estimate is A ) $251.50

Please help which property is illustrated by this example (5 . 15) . 4 = 5 . (15 . 4)

Talja [164]

Answer:

This is the commutative property of multiplication.

Step-by-step explanation:

We know this because that property states that it does not matter what order the numbers are multiplied together, as long as they are all being multiplied. So even though the numbers change on both sides, it does not affect the answer.

Sin^2x/cos^2 + sinxcscx = sec^2x Identify it, please explain so I know how you did it, thanks

max2010maxim [7]

$\frac{sin^2x}{cos^2x} + sin x *cscx\\ tan^2x + \frac{sin x}{sin x} \\ tan^2x + 1\\ sec^2x$

$\frac{sin^2x}{cos^2x} = tan^2x$

$csc x = \frac{1}{sinx}$

$tan^2x + 1 = sec^2x$

In the following diagram, BC is parallel to DE 30 POINTS

Romashka-Z-Leto [24]

Answer:

29

Step-by-step explanation:

In parallel lines, allied angles have a sum of 180.

Therefore, angle CBD + angle EAB = 180

Therefore, 42 + 109 + x = 180

x + 151 = 180

x = 29

The Cinemania theater showed 108 different movies last year. Of those, 15 movies were action movies. Based on this data, what is

natita [175]

Answer:

A reasonable estimate of the probability is equal to $0.1389$ or $13.89\%$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y-----> size of the sample space

so

$P=\frac{x}{y}$

In this problem we have

$x=15$

$y=108$

substitute

$P=\frac{15}{108}=0.1389$

Convert to percentage

$0.1389*100=13.89\%$
