Answer:

$2.28

Step-by-step explanation:

Football: $22.50

Gloves: $15.50

Total: $38.00

Sales tax is 6%

So the amount of money paid in Sales Tax is (6/100) * $38.00  = $2.28.

Total purchase price is: $40.28

Answer:

The coordinates of R' are [tex]R'(x,y) = (8,-2)[/tex].

Step-by-step explanation:

According to Linear Algebra, dilation consist in expanding a given vector with  respect to one of its endpoints by a scalar. That is:

[tex]R'(x, y) = C(x,y) + k\cdot [R(x,y)-C(x,y)][/tex] (Eq. 1)

Where:

[tex]R(x, y)[/tex] - Original location with respect to origin, dimensionless.

[tex]C(x,y)[/tex] - Point of reference with respect to origin, dimensionless.

[tex]k[/tex] - Dilation factor, dimensionless.

[tex]R'(x, y)[/tex] - Dilated point with respect to origin, dimensionless.

If we know that [tex]R(x,y) = (3,8)[/tex], [tex]C(x,y) = (2,10)[/tex] and [tex]k = 5[/tex], then the dilated point is:

[tex]R'(x,y) = (3,8) +5\cdot [(3,8)-(2,10)][/tex]

[tex]R'(x,y) = (3,8)+5\cdot (1,-2)[/tex]

[tex]R'(x,y) = (8,-2)[/tex]

The coordinates of R' are [tex]R'(x,y) = (8,-2)[/tex].

Answer:

x=3√2 or x=4

Step-by-step explanation:

5*x^3-2*x^2=18

x^2(5x-2)=18

x^2=18 or 5x-2=18

x=√18 or 5x=20

x=√9*2 or x=4

x=3√2 or x=4

Answer:

The answer is "0.43"

Step-by-step explanation:

Population proportion normal distribution is suggested as following:

Confidence Interval = [tex]P \pm Z \times \sqrt{\frac{P \times (1 -p)}{n} }[/tex]

Confidence Interval = [tex]P \pm E[/tex]

Bottom bound [tex]= P-E = 0.23[/tex]

Lower bound [tex]= P + E = 0.63[/tex]

Through connecting additional formulas, we're getting,

[tex]\to 2P = 0.23+0.63\\\\\to 2P = 0.86\\\\\to P= \frac{0.86}{2}\\\\[/tex]

        [tex]= 0.43[/tex]

The average with all attribute outcomes a whereby the demographic proportion at 5 % isn't dismissed as plausible values is 0.43.

Step-by-step explanation:

Answer:

they want a fomula that is in respect to 'b"  sooo..

Step-by-step explanation:

just do the algebra.... like so..

a/b=c

move 'b" across = sign by multiplying by 1/b  like soo.

(1/b)*(a/b)=  (1/b)*c

a=c/b

then move the 'c' to the other side of the = sign  by multiplying by 1/c

(1/c)*a = (1/c)*(c/b)

a/c = b    

makes sense  , also.. as a way to speed that up.. just remember you can just swap the  'b'  and 'c'  in that first equation  

b = a/c

Answer:

y=3/4x

Step-by-step explanation:

Better known as C.

I chose this answer choice because I pulled up a graphing calculator and the result I got was y=3/4x (aka, C)

The equation that best represents the direct variation function is y = 3/4x; option C.

A direct variation function is a function in which the domain and range of a function varies directly.

The direct variation function contains the points (–9, –3) and (–12, –4)

Therefore, the equation that best represents the direct variation function is y = 3/4x.

Answer:

  17.50 down

Step-by-step explanation:

After the discount, the price is 100% -10% = 90% of the original.

After the tax, the amount owed is 100% +8% = 108% of the discounted price.

The amount Jordan put down is 15% of the amount after tax, so is ...

  120(0.90)(1.08)(0.15) ≈ 17.50 . . . down payment

Answer:

It tells us that if A=B and B=C, then A=C. The transitive property of order uses the same idea, except with < or ">> signs instead of = signs

Step-by-step explanation:

Answer:

the transitive property states that: If a = b and b = c, then a = c. In other words, if a is related to b by some property, and b is related to c by the same property, then a is related to c by that property.

Answer:

d = 4t + 60

Step-by-step explanation:

If Bryson jogged at a constant rate of constant speed and he starts a timer when he is 20 feet from his starting position. after 5 seconds, his speed will represent the slope of the required equation:

Speed = distance/time

Speed = 20 feet/ 5 secs

Speed = 4ft/s

Hence the slope of the equation is 4ft/s

Next is to get the intercept c

Standard equation that represents the expression is:

d = mt+c

d is the distance of bryson from his starting position

To get the intercept c, substitute d = 80, m = 4 and t = 5 into the equation as shown:

80 = 4(5) + c

80 = 20 +c

c = 80 - 20

c = 60

Get the equation:

Substitute m = 4 and c = 60 into the original equation

d = mt + c

d = 4t + 60

Hence a linear equation in slope-intercept form to find the distance d of bryson from his starting position after t second​ is d = 4t + 60

Step-by-step explanation:

Don't be too quick to answer 15% of some number. It may be right, but it is likely not.

James makes 9.00 dollars an hour

Priya makes 20% more than James. Stop. Figure that out.

9.00 * 1  + 25/100 * 9 = 9.00 + 2.25 = 11.25

Now, you can figure out 5% less.

Siobhan = 11,25 - 5/100 * 11.25

Siobhan = 11.25 - 0.05 * 11.25

Siobhan = 11.25 - 0.5625

Siobhan = 10.6875 = 10.69

There is no other way that I know of to go directly to Siobhan's wage other than doing it the long way -- at least for the level of math you are taking.

9 * (1.2 - 0.05) might work.

9 * (1.15)

= 10.35 which is close, but not correct.  

Moral: do the math. Don't accept a guess as an answer.

Answer:

3,290 inches of Ribbon

Step-by-step explanation:

Assuming that Sarah needs a total of 1,000 Ribbons we would simply need to multiply this total amount by the size of each individual Ribbon, which according to Sarah is 3.29 inches. This is because this would be like adding the size of each individual ribbon to get the total length. Like so...

1,000 * 3.29 = 3,290inches

Therefore, Sarah would need a total of 3,290 inches or

3,290 / 12 = 274.16ft of ribbon

Answer:

5 pounds

Step-by-step explanation:

Total pounds of fertilizer purchased purchased for lawn = 9 pounds

Amount used for backyard = 2 2/3 pounds

Amount used for front yard = 1 2/9

Amount of fertilizer left :

Total amount purchased - total. Amount used

Total amount used :

(amount used for backyard + amount used for front yard)

(2 2/3 + 1 2/9) = (8/3 + 11/9) = (24 + 11) / 9

= 36 / 9

= 4 pounds

Amount of fertilizer left :

Total amount purchased - total. Amount used

9 pounds - 4 pounds

= 5 pounds

Answer:

number of bracelets= 5

number of necklaces= 4

Step-by-step explanation:

* I don't know how to show a matrix with a keyboard so I'm just going to do two lines of brackets to represent the matrix.

b=bracelets

n=necklaces

[8   20  | 120]

[b   n    |  9   ]

You should put this into a graphing calculator:

[8   20  | 120]

[1     1    |  9   ]

Then use reduced row echelon form which equals:

[1   0   |   5]

[0   1   |   4]

The top line being the number of bracelets and the bottom line being the number of necklaces
