Answer:

Step-by-step explanation:

the total price for clothes= 24.95+14.95=39.90

sales tax 39.90*9.5/100=3.79

the total paid to the clerk will be=39.90+3.79=43.69

Answer: 6 or 20 would be the amount. (if there was only one, then i revise this.)

Answer: [tex]f(t)=550t[/tex]

Step-by-step explanation:

Given

Distance between Toronto to Dallas is 1200 miles

speed of the plane is 550 mph

We know, [tex]distance=speed\timestime[/tex]

for any time t, distance is given by

[tex]distance=f(t)=550\times t[/tex]

where t is hours

for [tex]t=0,f(t)=0[/tex] i.e. plane is at Dallas at 2 pm

time taken to reach dallas is [tex]\dfrac{1200}{550}=2.18\ \text{hr}[/tex]

Answer:

(-4,-10) and (5,-3)

Step-by-step explanation:

To be honest, this kind of question allows for any coordinates as long as they have the slope of 9/7.

I know the slope equation is (y2-y1)/(x2-x1) = m (where m is slope)

(y2-y1)/(x2-x1) = 9/7

From this equation, find any two numbers that have a difference of 9 to the y-coordinates.

I'll go with 5 and -4 (y-coordinates)

And two integers that have a difference of 7 for the x-coordinates.

I go with -3 and -10 (x- coordinates)

So the points I got are,

(5-(-4))/((-3)-(-10)) = 9/7

5-(-4) is equal to 5+4 (2 minus signs are equal to 1 plus sign), which is 9.

(-3)-(-10) is equal to -3+10 (2 minus signs are equal to 1 plus sign), which is 7.

The two points are (-4,-10) and (5,-3)

Notice if we were to subtract 5 from -4, we would also have to subtract -3 from -10.

-4-5= -9 and -10- -3 = -10+3 = -7

-9/-7 is the same as 9/7.

Basically, (-4,-10) and (5,-3) are different coordinates and you can only switch them as coordinate 1 or 2 but not the points.

Sorry, took a while, hope I was able to help! Good Luck.

Answer:

The rate of change is of 2.25 degrees per hour.

Step-by-step explanation:

The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).

In this question:

From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours

The change in temperature was of 76 - 58 = 18º

Rate of change:

18º/8 = 2.25º

The rate of change is of 2.25 degrees per hour.

Answer: C

Step-by-step explanation:

Answer:

See Explanation below.

Step-by-step explanation:

What the workers can do to ensure the patio is truly rectangular, before pouring the concrete, is to measure the length of the sides of the patio.

This requires full knowledge of the physical properties of a rectangle.

The opposite sides of a rectangle (the two sides which go in the same direction or which are parallel to each other) are equal in length and one set of parallel sides must be longer than the other set of parallel sides.

These are the conditions that the patio must satisfy, to be truly rectangular.

Once the workers have made sure of this, they can go ahead and pour the concrete.

Answer:

The average rate of change of the function over the interval is of 2.

Step-by-step explanation:

Suppose we have a function f(x), over an interval (a,b).

It's average rate of change over the interval is given by:

[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]

In this question:

[tex]g(x) = x^2 + 10x + 19[/tex]

Over the interval -9 < x < 1, so [tex]a = -9, b = 1[/tex]. So

[tex]A = \frac{g(1) - g(-9)}{1 - (-9)} = \frac{g(1) - g(-9)}{10}[/tex]

We have that:

[tex]g(1) = 1^2 + 10(1) + 19 = 1 + 10 + 19 = 30[/tex]

[tex]g(-9) = (-9)^2 + 10(-9) + 19 = 81 - 90 + 19 = 10[/tex]

So

[tex]A = \frac{30 - 10}{10} = \frac{20}{10} = 2[/tex]

The average rate of change of the function over the interval is of 2.

Answer:

First one is 6 16/21

Second one is 3 14/15

Step-by-step explanation:

Answer:

Metals which react with steam form the solid metal oxide and hydrogen gas.

In general, the more reactive the metal, the more rapid the reaction. Aluminium is unusual, because it is a reactive metal that does not react with water. Its surface forms a protective layer of aluminium oxide that keeps water away from the metal below.

The apparatus used to react a metal with steam and collect the gas produced is shown below.

Answer:

This is because some metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen.

a)[tex]X=1728[/tex]

b)[tex]X'=220[/tex]

Step-by-step explanation:

From the question we are told that

Population size N=12

Sample size n=3

a)Generally using theoretical sampling we can solve mathematically

   [tex]X=N^n[/tex]

   [tex]X=12^3[/tex]

   [tex]X=1728[/tex]

b)Generally using experimental sampling we can solve mathematically

[tex]X'=^NC_n[/tex]

[tex]X'=^1^2C_3[/tex]

[tex]X'=220[/tex]

Answer:

I'm pretty sure it's 195 times

Step-by-step explanation:

(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95

95 + 100 (from 300's) = 195

Answer:

pretty sure it's 195 times

Step-by-step explanation:

(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95

95 + 100 (from 300's) = 195
