If four boys each ate two thirds of a pizza, how many pizza's did they consume all together ?

Step-by-step explanation:

4 × [tex]\frac{2}{3}[/tex] = 2 [tex]\frac{2}{3}[/tex]

Answer:

2 2/3 pizzas

Step-by-step explanation:

One boy consumes 2/3 of a pizza

Four boys consume 4(2/3) pizza

4(2/3) = 8/3 = 6/3 + 2/3 = 2 2/3 pizzas

Answer:

2

Step-by-step explanation:

Using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

let

[tex]log_{2}[/tex] 8 = n ⇒ 8 = [tex]2^{n}[/tex] , that is

2³ = [tex]2^{n}[/tex] ( equate exponents )

n = 3

and let

[tex]log_{3}[/tex] ( [tex]\frac{1}{3}[/tex] ) = n ⇒ [tex]\frac{1}{3}[/tex] = [tex]3^{n}[/tex] , that is

[tex]3^{-1}[/tex] = [tex]3^{n}[/tex] ( equate exponents )

n = - 1

then

[tex]log_{2}[/tex] 8 + [tex]log_{3}[/tex] ([tex]\frac{1}{3}[/tex] )

= 3 + (- 1)

= 3 - 1

= 2

Answer:

y+5=2(x+3)

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=2(x-(-3))

y+5=2(x+3)

Step-by-step explanation:

there must be some additional information missing (like the domain of the function), because just as it is written here, the function f(x) would not have any limitations, and its range would be -infinity < y < +infinity.

so, it is impossible to tell you which answer option is correct.

because again, based on the given information, none of these options is correct.

Eddie's account can be modelled as a linear function.

Ely's account can be modelled as an exponential function.

Ely's account  would be higher than Eddie's account by $207.98.

A linear function is a function that has one variable that is raised to the power of 1. An example is 5x + 2.

Eddie's account can be modelled as a linear function because it increases by $240 every year. The linear function is $3000 + $240x. Where x is the number of years.

An exponential function is a function that is in the form y = [tex]a^{x}[/tex].

Ely's account can be modelled as an exponential function because it increases by [tex]1.08^{x}[/tex]. The exponential function is $3000 x  [tex]1.08^{x}[/tex]. Where x is the number of years.

Value of Eddie's account in 5 years = $3000 + $240(5) = $4,200

Value of Ely's account in 5 years = $3000 x  [tex]1.08^{5}[/tex] = $4,407.98.

Difference = $4,407.98 - $4,200 = $207.98

The table is an illustration of a linear and an exponential function.

From the table, we can see that Eddie's balance increase by 240 each month.

This represents a linear function.

Also, we can see that Ely's balance increases at a rate of 8% each month.

This represents an exponential function.

So, we have:

[tex]y = 3000 + 240x[/tex] -- Eddie's account

[tex]y = 3000(1.08)^x[/tex] --- Ely's account

In (a), we have:

[tex]y = 3000 + 240x[/tex] -- Eddie's account

[tex]y = 3000(1.08)^x[/tex] --- Ely's account

So, their balance in 5 years is:

[tex]y =3000 + 240*5[/tex]

[tex]y =4200[/tex]

[tex]y = 3000(1.08)^5[/tex]

[tex]y = 4408[/tex]

Calculate the difference (d)

[tex]d = 4408 - 4200[/tex]

[tex]d = 208[/tex]

Hence, Ely's balance would be $208 greater than Eddie's

No of extra miles:-

Now

Total average miles

[tex]\\ \tt\hookrightarrow 159+66.16=216.16mi/day[/tex]

The number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be 216.16 miles.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A Ford Taurus at Enterprise Rent-a-Car rents for $43.46 per day. You receive 150 free miles per day but are charged $0.25 per mile for any additional miles.

Let x be the number of miles that you drive and y be the total rent. Then the equation will be

y = 0.25(x - 150) + 43.46

Then the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be

60 = 0.25(x - 150) + 43.46

60 = 0.25(x - 150) + 43.46

16.54 = 0.25(x - 150)

66.15 = x - 150

x = 150 + 66.15

x = 216.16 miles

Thus, the number of miles that you can drive per day, on average, and not exceed your daily budget of $60.00 will be 216.16 miles.

Answer:

A = (81 - 20.25π)cm²

P = (18 + 9π)cm

Step-by-step explanation:

Since the answer asks for the exact value, we will keep π as itself to ensure there is no rounding off errors.

Firstly, finding the area A.

> Putting both semicircles together, you will get a full circle. Hence, finding the area only requires you to subtract the circle off the square.

>Also, the radius of the circle is [tex]\frac{9}{2}=4.5[/tex].

Thus,

[tex]A=9^{2} -(\pi *4.5^{2} )\\A= 9^{2}-20.25\pi\\A= (81-20.25\pi)cm^{2}[/tex]

Next, finding the perimeter B.

>Again, combining both arcs of the shaded figure together, we form a circumference of the circle.

Thus,

[tex]P = 2(9) + (2*\pi *4.5)\\=(18+9\pi )cm[/tex]

3x = x + 4

x = 2

3x = 6

x + 4 = 6

The value of x will be 0.48 which makes the following expression equal.

A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations. Mathematicians can multiply, divide, add, or subtract. An expression is structured as follows: Number/variable, mathematical operator, and expression.

It is given that the expression is, 9.3x = x +4

The value of x is obtained to make the expressions equal.

Apply the arithmetic operation in order to find the value of x.

9.3x = x +4

9.3x-x=4

8.3x=4

x=4/8.3

x=0.48

Thus, the expression below is equivalent since the value of x will be 0.48.
