Answer:

100/21

Step-by-step explanation:

A thing's extent, size, or the total amount is its quantity.

The mixture must contain 10 pounds of affordable tea.

An answer to the question "how much?" is a quantity, which might be an amount, number, or measurement.

Numbers or unconventional units can be used to express quantities.

Quantity in more complex mathematics can also refer to an undetermined amount in an equation.

Affordable tea costs $2.00.

The price for superior tea is $5.

The price of blended tea is $4.25.

Solution:

$4.25 multiplied by 40 pounds of blended tea equals $170.

Let x represent the quantity of affordable tea, and

The superior tea quantity is (40 - x).

4.25 * 40 = 2x + 5(40 - x)

170 = 2x + 200 -5x

-3x = -30

x = 10

Therefore, the mixture should contain 10 pounds of affordable tea.

a) The small tire would  make 38  rotations

   The large tire would make 127  rotations

b) A bicycle with two large wheels would allow traveling faster with each rotation of the pedal .

The problem we are dealing with relates to rotations and circumference where rotation refers to the distance from the center to any point on the shape that remains the same and whereas the circumference is the perimeter of a circle. In one revolution a wheel covers a distance which is rise to its perimeter.Since we are provided that the diameter of the large wheel is 60 inches, so the radius will be 30 inches ( radius = diameter/2) and the radius of the small wheel is 9 inches.

The circumference of a circle  is 2πr

for a large wheel  the circumference is 2 x 3.14 X 30 = 188.4 inches

for a small  wheel, the circumference is  56.52

Since, we know 1 inch is equal to 0.0833333, as the traveling distance = 600 feet = 7200 inches.

Number of rotation = distance / circumference

For large wheel = 7200 /188.4 =38.21 = spprox 38

For small wheel = 7200/56.52 =127.38 = approx 127

Since we bicycle with bigger wheels is preferable as they can go faster than the ones with little wheels since their circumference is more as they cover more area in fewer rotations.

length×width = 108

length + 2×width = 30

length = 30 - 2×width

using that in the first equation

(30 - 2×width)×width = 108

-2×width² + 30×width - 108 = 0

the general solution to such a quadratic equation like

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

so,

width = (-30 ± sqrt(30² - 4×-2×-108))/(2×-2) =

= (-30 ± sqrt(900 - 864))/-4 =

= (-30 ± sqrt(36))/-4 = (-30 ± 6)/-4

width1 = (-30 + 6)/-4 = -24/-4 = 6 ft

width2 = (-30 - 6)/-4 = -36/-4 = 9 ft

for width = 6 ft

length = 30 - 2×width = 30 - 12 = 18 ft.

for width = 9 ft

length = 30 - 2×width = 30 - 18 = 12 ft

given the request that the length sound be as long as possible,

width = 6 ft

length = 18 ft

The probability of raffle ticket is a winner is 0.0002.

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

Given:

probability that your raffle ticket is not a winner = 0.9998.

Now, we know if we have to find the complement probability we can use

P(E) = 1 - P(not E)

where E is any event.

Here, E = not winner

So, P( raffle ticket is a winner)

= 1- 0. 9998                                                  

= 0.0002

Hence, the probability of raffle ticket is a winner is 0.0002.

If the point (x, y) rotated 180 degrees about the origin, then its image is (-x, -y)

Since point H is (1, 0), then

H' = (-1, 0)

Since point I is (4, 0), then

I' = (-4, 0)

Since point J is (2, 1), then

J' = (-2, -1)

Since point K is (-1, 1), then

K' = (1, -1)

The coordinates of the image after rotated 180 degrees about the origin are

Answer:

0.55

Step-by-step explanation:

( x1, y1 ) = ( 2, 11.9 )

Here,

x1 = 2

y1 = 11.9

( x2. y2 ) = ( 4, 13 )

Here,

x2 = 4

y2 = 13

Formula : -

Rise over run = ( y2 - y1 )/( x2 - x1 )

Rise over run = ( 13 - 11.9 )/( 4 - 2 )

The first offer is better from the perspective of a customer but the second one is better from the perspective of a seller.

Here we have different 2 cases, and to find the answer we have to follow a few steps.

First of all, we should simplify these two cases and will try to give them a proper equation format.

Let's assume the price of each yogurt is $x.

Therefore the total price of 2 pots is (2× x) = $2x.

But the condition is if we buy 2 pots, get the 3rd one for free. So, we can purchase a total of 3 pots at the same cost.

∵ If 3 pots cost $2x, then the average cost for each pot is 2x/3 =$0.67x

( average value of each unit = Total value / total unit )

In the second case, if we buy 1 pot we can get the second one at half price.

Therefore, the total price of two pots is, ( x + 0.5x ) = $1.50x

∵ If 2 pots cost $1.50x, then the average cost for each pot is 1.50x/2 = $0.75x

( average value of each unit = Total value / total unit ).

The price of yogurt per pot in the first case <  The price of yogurt per pot in the second case.

As $0.67 <  $0.75.

Answer:

Step-by-step explanation:

Given pairs of points that define three lines, you want to know their slopes, and whether line pairs are parallel or perpendicular.

The lines are defined by point pairs ...

The slope of a line is given from a pair of points by the formula ...

  m = (y2 -y1)/(x2 -x1)

Lines with the same slope are parallel.

Lines with opposite reciprocal slope are perpendicular.

Line 1 slope = (8 -4)/(-3 -0) = 4/-3 = -4/3

Line 2 slope = (4 -(-2))/(4 -(-4)) = 6/8 = 3/4

Line 3 slope = (4 -1)/(8 -4) = 3/4

The slopes of the lines are ...

Lines 1 and 2 have slopes that are opposite reciprocals (-4/3 and 3/4), so are perpendicular.

Lines 1 and 3 have slopes that are opposite reciprocals (-4/3 and 3/4), so are perpendicular.

Lines 2 and 3 have identical slopes (3/4 and 3/4), so are parallel.

Let J be Jasmine age and S the sister's age. Then, we have

this equality means Jasmine is 5 years younger than twice her sister's age. Now, we also know that J=39 years then by substituying this value into the last equality, we have

and now, we can solve this equation for S. First, we must move -5 to the right hand side as 5. It reads

and finally, we obtain

therefore, Jasmine's sister has 22 years old.

If she thinks that after 8 months, she will have spent around $75.00 total.  Dominique's estimate is not reasonable?

We have to make use of the given data to find whether amount of $75 which she estimated that she will spent after 8 months is reasonable

Total cost:

Total cost =$15.50  + 10 × $0.99 × 8

Total cost = $15.50 + 9.9 × 8

Total cost = $15.50 +$79.2

Total cost = $94.7

Hence,

$94.70 ≥ $75.00

Based on the above calculation the amount she estimated is not a reasonable amount because the total cost is greater that the estimated amount.

Therefore we can conclude that the estimate is unreasonable.

The estimate of the Dominique's is not reasonable.

Given that,
Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonably is to be justified.

Here,
According to the question,
The total cost of the song for 8 months = 8 (0.99 x 10)
                                                            = $ 79.2
Total cost  = 15.50 + 79.2 = $94.7
Since the total cost exceeds Dominique's estimate so her estimate is not reasonable.

Answer:

y + 2 = 3/4 (x - 1)

Step-by-step explanation:

You would pick one of the points in this case I picked (1, -2), for point-slope form your equation is y - y1 = m(x-x1).

Finding the slope (m) is easy you just do rise (up/down) OVER run (left/right).

So in this case your slope (m) is 3/4.

then you just plug everything in but because two negatives equal a positive you equasion should look like this y + 2 = 3/4(x - 1)
