Explanation:

Imagine drawing a circle and splitting it into 3 equal slices. Repeat this process to get 12 identical such circles. We have 12*3 = 36 slices so far.

Then add a 13th circle that has 2 of the 3 slices shaded, to represent 2/3. So we add 2 extra slices to the 36 original to get 36+2 = 38 total slices.

Each slice represents 1/3 of a cup. So each full circle represents 1 full cup.

-------------

Another approach:

Let's convert the mixed number 12 & 2/3 into an improper fraction

We use the formula

a & b/c = (a*c+b)/c

So,

12 & 2/3 = (12*3+2)/3 = (36+2)/3 = 38/3

Then rewrite the 38/3 as 38*(1/3) to show we have 38 copies of the 1/3 cup.

Answer: 38 cups

Step-by-step explanation:

       We will divide 12 2/3 cups by our measurement, 1/3 cup, to find how many 1/3 cups will be needed.

(12 + 2/3) / (1/3) = 38 cups

Answer:

[tex](-5)[/tex] and [tex]3[/tex].

Step-by-step explanation:

The [tex]x[/tex]-intercepts of a graph refer to points where the graph intersects the [tex]x\![/tex]-axis. These are [tex]x\!\![/tex] values for which [tex]f(x) = 0[/tex].

For example, since [tex]x = (-5)[/tex] is one of the [tex]x[/tex]-intercepts of [tex]y = f(x)[/tex], it must be true that [tex]f(-5) = 0[/tex]. Likewise, since [tex]3[/tex] is one of the [tex]x[/tex]-intercepts of [tex]y = f(x)\![/tex], [tex]f(3) = 0[/tex].

Since [tex]f(-5) = 0[/tex], the expression [tex]7\, f(-5)[/tex] would also evaluate to [tex]0[/tex] (that is, [tex]7\, f(-5) = (7)\, (0) = 0[/tex].) Thus, [tex]x = (-5)[/tex] would be an [tex]x[/tex]-intercept of the new graph [tex]y = 7\, f(x)[/tex].

Likewise, since [tex]f(3) = 0[/tex], [tex]7\, f(3) = (7)\, (0) = 0[/tex], such that [tex]x = 3[/tex] would also be an [tex]x[/tex]-intercept of the new graph [tex]y = 7\, f(x)[/tex].

No other points could be an [tex]x[/tex]-intercept of the new graph [tex]y = 7\, f(x)[/tex] without being an [tex]x\![/tex]-intercept of [tex]y = f(x)[/tex]. For example, assume that [tex]x = x_{0}[/tex] is an [tex]x[/tex]-intercept of [tex]y = 7\, f(x)[/tex] but not [tex]y = f(x)[/tex]. [tex]7\, f(x_{0}) = 0[/tex], such that [tex]f(x_{0}) = (1/7)\, (7\, f(x_{0})) = (1/7)\, (0) = 0[/tex]- contradiction.

Therefore, the [tex]x[/tex]-intercepts of the new graph would be [tex]x = (-5)[/tex] and [tex]x = 3[/tex].

The time it would take Shirley to mow the lawn alone is 3 hours

From the information given;

Let Shirley's working hours be x

Let Pam's working hours be y

We have  that;

Shirley and Pam work 6 hours together, this is expressed as;

x + y = 6

Given that Pam work 3 hours alone, we have;

y = 3

Substitute the value of y as 3 in the equation

x + 3 = 6

x = 6 - 3

x = 3

Thus, the time it would take Shirley to mow the lawn alone is 3 hours

The time that it will take the ball to hit the ground in 4 seconds.

To solve this problem you need the function;

h(t) = -16t² + v₀t + h₀

where;

t = time

v₀ is the initial velocity, which in our case is 0

h₀ is initial height, which in our case is 121 ft

h(t) = 0 since we want to know when the ball will hit the ground.

Thus;

0 = -16t² + 121

And we can solve for t;

If we rearrange the terms we see that this is a difference of 2 squares

0 = 121 - 16t²

0 = (11 - 4t)(11 + 4t)

Setting each factor = 0 gives;

11 - 4t = 0       11 + 4t = 0

t = 11/4       or      t = -11/44

The second solution is discarded as time cannot be negative.

Thus, the ball will hit the ground in 4 seconds.

The value for the given question is x₁ = 1.8, x₂ = 1.85, x₃ = 1.846.

Given iteration formula as xₙ ₊ ₁ = ∛ 10 - 2xₙ

Given x₀ = 2

We have to find the values of x₁, x₂, and x₃ as

For finding the value of x₁ we need to substitute n = 0 as

xₙ ₊ ₁ = ∛ 10 - 2xₙ

x₀ ₊ ₁ = ∛ 10 - 2x₀

x₁ = ∛ 10 - 2(2)    (∵ x₀ = 2)

x₁ = ∛ 10 - 4

x₁ = ∛ 6

x₁ = 1.8

For finding the value of x₂ we need to substitute n = 1 as

xₙ ₊ ₁ = ∛ 10 - 2xₙ

x₁ ₊ ₁ = ∛ 10 - 2x₁

x₂ = ∛ 10 - 2(1.8)    (∵ x₁ = 1.8)

x₂ = ∛ 10 - 3.6

x₂ = ∛ 6.4

x₂ = 1.85

For finding the value of x₃ we need to substitute n = 2 as

x₂ ₊ ₁ = ∛ 10 - 2xₙ

x₂ ₊ ₁ = ∛ 10 - 2x₂

x₃ = ∛ 10 - 2(1.85)    (∵ x₀ = 1.85)

x₃ = ∛ 10 - 3.7

x₃ = ∛ 6.3

x₃ = 1.846

Therefore, the value of x₁ = 1.8, x₂ = 1.85, x₃ = 1.846.

Answer:

Step-by-step explanation:

Answer:

Number of 12$ Shares? 25

Number of 14$ Shares? 57

Step-by-step explanation:

Let x = number of $12 shares.

Let y = number of $14 shares.

"Ivan has $1098 worth of $12 and $14 stock shares."
12x + 14y = 1098

The number of $14 shares is seven more than twice the number of $12 shares.

y = 2x + 7

We have a system of equations.

12x + 14y = 1098

y = 2x + 7

We can use the substitution method since the second equation is already solved for y. Substitute 2x + 7 for y in the first equation.

12x + 14(2x + 7) = 1098

12x + 28x + 98 = 1098

40x = 1000

x = 25

There are 25 $12 shares.

y = 2x + 7 = 2(25) + 7 = 57

There are 57 $14 shares.

Check:

25 × $12 + 57 × $1`4 = $300 + $798 = $1098

Answer:

[tex](3/4)[/tex] and [tex](2/3)[/tex].

Step-by-step explanation:

For a fraction of the form [tex](p / q)[/tex], the number in front of the division ([tex]p[/tex]) is the numerator. The number after the division ([tex]q[/tex]) is the denominator.

[tex]\begin{aligned} \frac{p}{q} \quad \genfrac{}{}{0}{}{(\text{numerator})}{(\text{denominator})}\end{aligned}[/tex].

A positive fraction [tex](p/q)[/tex] ([tex]p,\, q > 0[/tex]) is less than [tex]1[/tex] as long as the numerator [tex]p[/tex] is smaller than the denominator [tex]q[/tex] (that is, [tex]p < q[/tex].) The reason is that as long as [tex]p,\, q > 0[/tex]:

[tex]\begin{aligned} & \frac{p}{q} < 1 \\ \iff & (q)\, \left(\frac{p}{q}\right) < (q)\, (1) && (\text{given that $q > 0$}) \\ \iff & p < q\end{aligned}[/tex].

For example, in the fraction [tex](2/3)[/tex], [tex]2[/tex] is the numerator while [tex]3[/tex] is the denominator. Both the numerator and the denominator are positive, while the numerator [tex]2\![/tex] is smaller than the denominator [tex]3\![/tex]. Therefore, [tex](2/3)[/tex] would be less than [tex]1[/tex].

The solution interval for x is x ∈ (-1/4 , ∞)

An inequality shows the relationship of a non-equal comparison between two numbers or mathematical expressions.

Here, we are given two inequalities

x/4 > -1 and -4x - 4 < -3

Let us take the first equation

x/4 > -1

⇒ x > 4(-1)

x > -4

Now, the second equation

-4x - 4 < -3

-4x < -3 + 4

-4x < 1

Now since we are dividing both sides by a negative number, that is 4, the sign of the inequality will be reversed,

x > 1/-4

x > -1/4

Thus, we get x > -4 and x > -1/4

This means that all values of x greater than -1/4 will satisfy.

Thus, x ∈ (-1/4 , ∞)

Medicine is often prescribed on a "per day" basis. In 24 hours, this rate would be ...

She will spend £250 and save £400.

Ratio is an expression that indicates how many times one quantity is more than the other.

Here, we are given that Miss penny inherits £650.

Her saving to spending ratio is 9 : 4

Thus, the proportion of money she saves is 9/ (4+9) = 9/13

therefore, the amount of money saved will be-

9/13 of 650

= 9/13 * 650

= 9 * 50
