Answer the questions below.

The horizontal axis represents the time in hours, and the vertical axis represents the number of miles ran.

So for the first part we have 3 miles in 30 minutes (0.5 hour), so we can draw a line from point (0, 0) to point (0.5, 3)

For the second part, he rests for 15 minutes (0.25 hour), so the y-value doesn't change, therefore we have a horizontal line from (0.5, 3) to (0.75, 3).

Then, we have 2 miles in 15 minutes, so we have a line from (0.75, 3) to (1, 5).

And finally, 1 mile in 15 minutes, so a line from (1, 5) to (1.25, 6).

Hence,

The value of x= 64°

The value of y = 116°

The slope of the red line is 5. The correct answer is option B. 5

Two parallel lines, always have the same slope. Since the green and red line are parallels and the green line has slope 5, the slope of the red line is also 5.

Answer:

Y=-1/4x+-6

Step-by-step explanation:

convert the line to slope intercept form

x is the slope and the last thing is the y intercept

The greatest number of plates he can make to share is 6.

From the information, Gabe has just moved to a new town and wants to share plates of baked goods with his neighbors and he has 16 cookies and 24 brownies to share.

It should be noted that this illustrates that we have to find the highest common factor for 16 and 24.

This will be:

18 = 2, 3, 6, 9 and 18.

24 = 2, 3, 4, 6, 8, 12 and 24

The highest common factor is 6.

Therefore, the number will be 6 plates.

Firstly, we have to write the general depreciation fomula as follows;

where V(t) represents the value of the commodity after a certain t years

I is the initial value of the item

r is the annual percentage change (rate of depreciation)

t is the number of years

a) Here, we want to calculate the annual rate of change

According to the data given in the question;

V(t) = $13,000

I = $41,000

r = ?

t = 2004-1994 = 10 years

Now, we proceed to substitute these values, to find the find of r as follows;

b) To write r in percentage form, we have to multiply the answer in 'a' above by 100

We have this as ;

c) Here, we want to get the car value by year 2009

In that instance;

V(t) = ?

I = $41,000

r = 0.1085

t = 2009-1994 = 15

Substituting these values, we have;

To the nearest 50 dollars, this is $7,300

Molly gave away 90 trading cards out of 250 trading cards to her friend Carol.

Initially molly had 250 cards.

She gave away n trading cards to her friend.

Now molly has (250 - n) trading cards.

Initially Marcus had 4430 trading cards.

The number of cards that Marcus gave away is is three times of molly.

Cards gave away by Marcus = 3n

Now, Marcus is left out with (430 - 3n) trading cards/

After giving away the cards,

Molly and Marcus had same number of trading cards.

So, we can write,

250-n = 430-3n

Now, we have a linear relation between the number of cards given away and the remaining cards,

Further solving,

2n = 180

n = 90.

So, Molly gave away 90 cards.

The probability of having an even or a number greater than 9 is 2/3.

Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1.

The sample space of two 6-sided dice would be 36

Of this 36, there would be 18 which would have an even sum.

There would be 6 with a sum greater than 9.

The probability of having an even or a number greater than 9 = (18/36) + (6/36) = 24 / 36 = 2/3

Answer:

  5/9

Step-by-step explanation:

You want the probability that a roll of 2 dice will produce a sum that is even or greater than 9.

Half the numbers on each die are even. Their sum will be even when the dice show ...

  even + even . . . . p = (1/2)(1/2) = 1/4

  odd + odd . . . . . . p = (1/2)(1/2) = 1/4

So, the 36 possible outcomes will produce an even sum (1/4) +(1/4) = 1/2 of the time. That is, there are 1/2(36) = 18 outcomes with an even sum.

The sums that are greater than 9 are 10, 11, 12. Of these, 10 and 12 are outcomes that are even, so are already counted.

The sum 11 can be made two ways: 6 +5 or 5 +6.

So, "or greater than 9" adds 2 outcomes to the 18 we have already counted.

The final tally of outcomes of interest is ...

  18 + 2 = 20 . . . . of 36 possible outcomes

That is ...

  P(even or >9) = 20/36 = 5/9

Answer:

The answer is A

Answer:

length = 46cm

Step-by-step explanation:

The length of a rectangle is double its width. If the rectangle has a perimeter of 138cm, find its length (in cm).

p = 2l + 2w

when l = 2w, substitute in to equation:

138 = 2(2w) + 2w

138 = 4w + 2w

138 = 6w

divide both sides by 6:

138/6 = 6w/6

so width = 23cm

and we know that length = 2 width so:

length = 23cm × 2

length = 46cm

In the local hamburger shop the total number of hamburgers sold on Wednesday , based on the given data is :

325 hamburgers.

A General Rule for Equation Solving

here form a equation based on given data ;

let ,  Hamburgers be = x

let, Cheeseburgers be = y

here , No. of burgers (hamburgers and cheeseburgers )sold  = 598

here,

x + y = 598 =>(1)

y = x - 52  => (2)

solving 2 equations ,

x + ( x - 52 ) = 598

x + x - 52     = 598

2x = 598 + 52

x = 650 /2

x =  325

Step-by-step explanation:

You want to know the value of x that correctly solves the equation 3.2x -5 = -40.2.

The final velocity of the Ferrari will be 84.53 km/h. with an initial velocity of 10 km/h, accelerates at a rate of 50 km/h/min for 3 minutes.

This is a typical question from Newtonian mechanics. To solve this problem we have to convert all the given data into a standard unit like C.G.S.

Now, we will convert 10 km/h and 50 km/h by using the formula. (km/h × 5/18 = m/s )

10 km/h = 10× 5/18 = 2.78 m/s

50 km/h = 50× 5/18 = 13.89 m/sec/min = 0.23 m/s²

3 min = 3 × 60 = 180 sec. ( 1 min = 60 sec )

Now, we have to use the formula from Newton's law of motion,

v = u + at/2 .

Now we can calculate the final velocity,

v = 2.78 + (0.23 × 180)/2 = 2.78 + 20.7 = 23.48 m/s

Now, we have to calculate the velocity in km/h, which is (23.48 × 5 )/8 = 84.53 km/h. as we know (km/h = m/s ×18/5 ).

Therefore, the final velocity will be 23.48 m/s according to the given inputs and criteria.
