On Monday, Lou drives his ford escort with 28-inch tires, averaging x miles per hour. On Tuesday, Lou switches the tires on his

weeeeeb [17]

Answer:

$\% Change = \frac{|28-32|}{32} *100 = 12.5\%$

(B) Decrease by 12.5%

Step-by-step explanation:

For this case we know that the revolution is proportional to the circumference.

And we know that the average number of revolutions of 32 inch tires for Tuesday is higher than the original value of 28 inch tires for Monday.

We know that we have x mi/hr, so we can select a value fo x in order to find the average revolutions with the following formula:

$Avg = \frac{x}{mi}$

Let's say that we select a value for x for example x= 28*32 = 896, since this value is divisible by 32 and 28.

If we find the average revolutions per each case we got:

Tuesday:

$Avg = \frac{896}{32}=28$

Monday:

$Avg = \frac{896}{28}=32$

And then we can find the % of change like this:

$\% Change= \frac{|Final-Initial|}{Initial} *100$

And if we replace we got:

$\% Change = \frac{|28-32|}{32} *100 = 12.5\%$

Because we are assuming that the initial amount is the value for Monday and the final value for Tuesday.

So then the best answer for this case would be:

(B) Decrease by 12.5%

Does antibiotics help kill the common cold??

<span>Antibiotics don't work on the common cold. They fight bacteria-related illnesses. Colds are caused by viruses, so antibiotics won't do you any good. They can, however, do you harm.</span><span>Mar 29, 2016</span>

HELP ME PLEASE GUYS ! :)

Gnesinka [82]

Answer:

(12, 1)

Step-by-step explanation:

Arbitrarily choose y = 1. Then x - 6y = 6 becomes

x = 6(1) + 6, or x = 12.

Thus, one (of many) point on the graph is (12, 1).

if a pair of standard dice are rolled what is the probability that one die shows a six but not both of them. reduced fraction an

Novay_Z [31]

Answer:

$P=\frac{5}{18}$

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

if a die is rolled the sample space is

$\{1,2,3,4,5,6\}$

if two dice rolled the sample space is

$\{1,2,3,4,5,6\}*\{1,2,3,4,5,6\}$

so

The possible pairs are

$y=6*6=36$

The size of the event space x is

$\{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$x=10$

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

substitute

$P=\frac{10}{36}$

Simplify

$P=\frac{5}{18}$

In this figure, a || b | c and m/1 = 50°

zlopas [31]

The value of m<3= 130

The correct option is (c)

<h3>What is alternate interior angle?</h3>

Given:

m<1= 50

m<1+ m<2= 180 (Linear pair)

m<2= 180-50

m<2=130

Now, m<2 = m<3 [alternate interior angles]

m<3= 130

Hence, the measure of <3 is 130.
