Answer:

565 cm

Step-by-step explanation:

Given that:

Radius of tire (r) = 30 cm

Number of complete rotations made = 3

To start with :

Obtain the Circumference : 2πr

Hence,

Circumference = 2 * π * r

= 2 * π * 30 = 6

= 188.49555 cm²

Length of trace of water left :

188.49555 * 3

565.48667

= 565cm (nearest cm)

Answer:

he got 3456 crayons.

Step-by-step explanation:

Answer:

slope: -4

equation: y = -4x – 10

Answer:

x = 7/24  y = -1/18

Step-by-step explanation:

3y = -4x + 1

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

*plug into the other equation

12x - 9(-4/3x + 1/3) = 4

12x + 12x - 3 = 4

24x = 7

x = 7/24

*now plug into original equation

y = (-4/3)(7/24) + 1/3

y = -1/18

Answer:

Expected rate of return  =7.1% (Approx.)

Step-by-step explanation:

Given:

Current stock price = $50

Divided d = $2

Growth rate g = 5 %

Find:

Expected rate of return

Computation:

Expected rate of return = D(1+g)/Current Price + g

Expected rate of return = [2(1+5%)/50] + 5%

Expected rate of return  =7.1% (Approx.)

Paul is wrong as first he has to convert their powers to the same value with base 10.

We use the scientific notation of numbers to write very large numbers in compact form.

In the scientific form, we write a number in the form of base×10ⁿ.

Where 0 ≤ base < 10 and n can be any rational number.

Given, Paul says (3.14 X 10⁵) + (2.53 X 10⁴) = 5.67 X 10⁵. he is wrong to add bases they must have the same power of 10.

∴  (3.14 X 10⁵) + (2.53 X 10⁴).

= (31.4 X 10⁴) + (2.53 X 10⁴).

= 33.93 X 10⁴.

214 boxes of chocolate, 321 bags of caramel corn item was sold.

Boxes of chocolate sell for $6 each and bags of caramel corn sell for

$5 each. A total of 535 items were sold and $2889 was

raised.

set of  of chocolate was sold x boxes,

because  a total of 535 items more sold .

so the caramel corn was sold (535 -x) bags,

and boxes of  chocolate sell for $6 each , bags of caramel corn for each and  $2889 was raised.

so 6 x+ 5.(535-x) = $2889.

6 x+ 5.535-x = $2889.

6 x+ 2675 - 5x = $2889.

6x - 5x =2889-265

x =214

so the caramel corn was sold 535-x =535-214 = 321

Caramel corn bags cost $5 apiece, while chocolate boxes cost $6 each. 535 products in total were sold, bringing in a total of $2889 then there exists 214 boxes of chocolate, 321 bags of caramel corn was sold.

Any one of the forms, including addition, subtraction, multiplication, and division, should be used for the algebraic expression. Bring the variable to the left side and the other values to the right side in order to find the value of x. To find the answer, simplify the values.

Let set of  of chocolate was sold x boxes,

because  a total of 535 items more sold .

so the caramel corn was sold (535 - x) bags, and boxes of  chocolate sell for $6 each , bags of caramel corn for each and  $2889 was raised.

From the given information, we get

6x + 5(535 - x) = $2889

simplifying the above equation, we get

6x + 5 × 535 - 5x = $2889

6x + 2675 - 5x = $2889

6x - 5x = 2889 - 265

x = 214

So the caramel corn was sold = 535 - x

Substitute the value of x in the above equation, we get

= 535 - 214

= 321

There exists 214 boxes of chocolate, 321 bags of caramel corn was sold.

Therefore, the correct answer is option b) 214 boxes of chocolate, 321 bags of caramel corn.

Answer:

As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]

Step-by-step explanation:

Given the equation

[tex]3x + 4 = 7[/tex]

solving the equation for x = 1

substituting the value of x = 1 in the equation

[tex]3\left(1\right)+\:4\:=\:7[/tex]

[tex]7=7[/tex]

As the L.H.S = R.H.S, so [tex]x = 1[/tex] is the solution to the equation [tex]3x + 4 = 7[/tex]

                                                     Part b)

Answer:

As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]

Step-by-step explanation:

Given the equation

[tex]\frac{x-3}{2}=6[/tex]

solving the equation for x = 15

substituting the value of x = 15 in the equation

[tex]\frac{15-3}{2}=6[/tex]

[tex]\frac{12}{2}=6[/tex]

[tex]6=6[/tex]

As the L.H.S = R.H.S, so [tex]x = 15[/tex] is the solution to the equation [tex]\frac{x-3}{2}=6[/tex]

                                                   Part c)

Answer:

As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]

Step-by-step explanation:

Given the equation

[tex]x^2=-2x+3[/tex]

solving the equation for x = -3

substituting the value of x = -3 in the equation

[tex]x^2=-2x+3[/tex]

[tex]\left(-3\right)^2=-2\left(-3\right)+3[/tex]

[tex]9 = 6 + 3[/tex]

[tex]9 = 9[/tex]

As the L.H.S = R.H.S, so x = -3 in the equation is the solution to the equation [tex]x^2=-2x+3[/tex]

Step one:

given data

For Daisy's Flowers

the cost is $39.95

an additional $2.95 for every rose

let the number of rose be x

the linear model for the cost is

y=39.95+2.95x-----------1

Step two

For  the competing florist  

the cost is $26

an additional $4.5 for every rose

let the number of rose be x

the linear model for the cost is

y=26+4.5x------------2

Step three:

equating the two above equations to find the number of roses x

we have

39.95+2.95x=26+4.5x

solve for x

39.95-26=4.5x-2.95x

13.95=1.55x

divide both sides by 1.55

x=13.95/1.55

x=9

Hence the number of roses that would make both florists' bouquets cost the same price is 9 roses

Number of people who attended the movie this month = 50

[tex]\frac{3}{4}[/tex] of x + 2 = 50

[tex]\frac{3x}{4}[/tex] + 2 = 50

[tex]\frac{3x}{4}[/tex] = 50 - 2

Answer:

Step-by-step explanation:

The slop of YZ is 1/2. The slope perpendicular would be opposite, making it -2.

Answer:

- 2

Step-by-step explanation:

Calculate the slope m of YZ using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = Y(- 7, - 4) and (x₂, y₂ ) = Z(5, 2)

m = [tex]\frac{2+4}{5+7}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2

The equivalent equations to  72x+12y=60 are:

The given equation is:

72x+12y=60

To find the equivalent equations, follow the steps below

Multiply the equation 72x+12y=60 by 10

10(72x) + 10(12y) = 10(60)

720x  +  120y   =  600

Divide the equation 72x+12y=60 by 12

(72x/12)  +  (12y/12) = 60/12

6x  +  y   =  5

y  =  5  -  6x

Divide the equation 72x+12y=60 by 72

(72x/72)  +  (12y/72) = 60/72

x  +  y/6  =  5/6

x  =  5/6  -  y/6
