Answer:

5305.1647 times

Step-by-step explanation:

The Circumference of a circle : πd

d = diameter of circle = 30 cm

Circumference of wheel = π * 30cm = 94.247779 cm

1km to cm

1km = 100000cm

5 km = 500000 cm

Hence, number of times wheel rotate on a 5km journey :

500000 cm / 94.247779 cm

= 5305.1647 times

Answer:

x = 1

Step-by-step explanation:

Were trying to solve for x so we would say 3 1/2 - 2 1/2 and we would be left with 1. So x=1, which you then substitute into the problem to make sure it's correct so 2 1/2 + 1 = 3 1/2.

Answer:

v = − 1 or v = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

[tex]v^{2}[/tex] − 2v = 3

Step 1: Subtract 3 from both sides.

[tex]v^{2}[/tex]  − 2v − 3 = 3 − 3

[tex]v^{2}[/tex]  − 2v − 3 = 0

Step 2: Factor left side of equation.

( v + 1 ) ( v − 3 ) = 0

Step 3: Set factors equal to 0.

v + 1 = 0 or v − 3 = 0

v = −1 or v = 3

Answer:

Margret is correct, Kevin is wrong.

Step-by-step explanation:

6^-4 can be written as (1/6)^4

By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4

Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

Answer:

$4

Step-by-step explanation:

If she have $6 so 6-2=4

If buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  [tex]a \div b[/tex]= a divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

Given that:

To find:

The amount she'd save if she buy only one such beanie baby.

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

As we know, total amount she could've spent  = $d

Also, because of 3 beanie babies cosing equal, and total cost being $d,

the cost of each beanie baby is:

$d divided in 3 equal parts =  d/3 dollars

Thus, we get:

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

Amount that she'd save = [tex]d - \dfrac{d}{3} \: \rm dollars[/tex]

We can write d = 3d/3 since dividing and multiplying a number by same non-zero number doesn't affect that number.

We do so, so that that both terms could get in fraction form with same denominator so that numerators could work directly.

[tex]d - \dfrac{d}{3} = \dfrac{3d}{3} - \dfrac{d}{3} = \dfrac{3d - d}{3} = \dfrac{2d}{3}[/tex]

Thus, if buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

Answer:

Explanation:

Cross multiply the following:

[tex] \frac{x}{100} = \frac{71.76}{138} [/tex]

x times 138 = 138x

100 times 71.76 = 7,176

Divide both sides by 138:

Answer:

y =three point score =  3

x = two point score = 4

Step-by-step explanation:

this question can be solved using simultaneous equation

x + y = 7  eqn 1

2x + 3y = 17  eqn 2

Multiply eqn 1 by 2 to derive eqn 3

2x + 2y = 14 eqn 3

Subtract eqn 3 from 2 :

y = 3

Substitute for y in eqn 1

x + 3 = 7

x = 4

2.25

per hot dog

per bag o' chips

Explanation:

5x +3y = 14.82

7 x+6y = 22.89

− 10x−6y = −29.64

7 x+6y = 22.89

−3x  = −6.75

x=2.25

5⋅2.25+3y = 14.82

3y = 14.82  − 11.25

y = 3.57 /3  = 1.19

The cost of each hot dog and bag of chips is $2.22 and $1.24

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, At a baseball game Henry bought 5 hot dogs and three bags of chips for $14.82. Scoot bought 7 hot dogs and 6 nags of chip for $22.98.

Let the unit prices of hot dogs and chips be h and c respectively,

Therefore, establishing the equations,

5h + 3c = 14.82...(i)

7h + 6c = 22.98....(ii)

Multiply eq(i) by 2 and subtract eq(ii) by eq(i)

(10h + 6c = 29.64) - (7h + 6c = 22.98)

3h = 6.66

h =2.22

Put h = 2.22 in eq (i)

5(2.22) + 3c = 14.82

11.1 + 3c = 14.82

3c = 3.72

c = 1.24

Hence, the cost of each hot dog and bag of chips is $2.22 and $1.24
