Answer: Jacob will be 16 (16.5) years old, which is half of Todd's age, in 4 years.

I respect the Todoroki profile pic :)

Step-by-step explanation:

33 ÷ 2 = 16.5

1/2 of Todd's age = 16.5 (16)

16 - 12 = 4 years (4.5 years to be specific)

I will have 11 cookies remaining.

The expression will be; Y = 33 - X

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. A linear equation can have more than one variable. If the linear equation has two variables, then it is called linear equations in two variables and so on.

For the first batch

Total = 36 - 33 (collected by dad)

Total = 33

Second batch

Let remainder = Y

Y = 33 - X

where X = teachers part

To find the remainder, X = 2/3 x Total

X = 2/3 x 33

X = 22

Therefore;

Y = 33 - 22

Y = 11

The checkpoint Odalis will be when they catch up to Jaquan is 0.1 km.

Given that, Jaquan passed a checkpoint jogging at a constant speed of 9 km/hr.

2 minutes later Odalis passed the same checkpoint.

Odalis runs at a constant speed of 12 km/hr.

We know that, 1 hour = 60 minutes

So, 2 minutes = [tex]\frac{2}{60}[/tex] hour

= [tex]\frac{1}{30}[/tex] hour

So, the distance = [tex]9\times\frac{1}{30}[/tex]

= [tex]\frac{3}{10}[/tex] km

When the speed is 12 km/hr, we get

Distance = [tex]12\times\frac{1}{30}[/tex]

= [tex]\frac{2}{5}[/tex] km

Now, [tex]\frac{2}{5} - \frac{3}{10}[/tex]

By evaluating the quadratic equations we will get:

3c(a-4)+3d(a+5) =  3*(a^3 - 8a^2 + 102a + 22)

Here we have two quadratic functions:

c(x)=x^3-2x and d(x)=4x^2-6x+8

And we want to find the value of the expression:

3c(a-4)+3d(a+5)

First, let's evaluate the functions in these values:

3*c(a - 4) = 3*[ (a - 4)^3 - 2*(a - 4)] = 3*(a - 4)*[ (a - 4)^2 - 2]

               = 3*(a -4)*(a^2 - 8a + 16 - 2)

               = 3*(a - 4)*(a^2 - 8a + 14)

               = 3*(a^3 - 12a^2 + 46a - 56)

3*d(a + 5) = 3*[ 4*(a + 5)^2 - 6*(a + 5) + 8]

                = 3*[ 4a^2 + 40a + 100  -6a - 30 + 8]

                = 3*[4a^2 + 36a + 78]

Then the expression is:

3c(a-4)+3d(a+5) = 3*(a^3 - 12a^2 + 46a - 56) + 3*[4a^2 + 36a + 78]

                           = 3*(a^3 - 12a^2 + 46a - 56 + 4a^2 + 36a + 78)

                           = 3*(a^3 - 8a^2 + 102a + 22)

  (a)  $1049.15

Step-by-step explanation:

You want to know the interest earned by an account that pays 3.2% interest compounded semiannually if the balance is $6049.15 after 6 years.

The formula for the balance of an account earning compound interest is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.

We have ...

  6049.15 = P(1 +0.032/2)^(2·6) = P(1.016^12)

The amount of interest earned is the difference between the account balance and the principal:

  interest = 6049.15 -(6049.15/1.016^12) ≈ 1049.15

The total amount of interest earned is $1049.15.

The diameter of the grindstone is decreasing at a rate of 5/(πr) cm/hr.

Therefore the answer is b) 5/ (πr) cm/hr.

The grindstone is losing material at a rate of 50 cm³/hr, and since it is a cylinder, we can use the formula for the volume of a cylinder to find the rate at which its diameter is decreasing.

The volume of a cylinder is given by:

[tex]V= \frac{ \pi D^{2} h}{4}[/tex]

where V is the volume, d is the diameter and h is the height (in this case the thickness of the grindstone).

We know that the grindstone is losing material at a rate of 50 cm³/hr, and that the grindstone's thickness is 10 cm. To find the rate at which the diameter is decreasing, we need to find the rate at which the radius is decreasing, which we can find by differentiating the volume equation with respect to time.

So

[tex]\frac{dV}{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{d(\frac{\pi\\D^{2}h }{4}) }{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{2}{4}\pi Dh\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]

Substitute the known values,

[tex]\frac{2}{4}\pi *(D)*(10cm)\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{dD}{dt}= (-50 cm^3/hr)*\frac{4}{2\pi *(D cm)*(10 cm)}[/tex]

[tex]\frac{dD}{dt}= \frac{-10}{\pi D}cm/hr[/tex]

We know D = 2r

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Kate is 4 years younger than Leo.

And, Twice Kate's age minus 3 is the same as Leo's age plus 9.

Now,

Let the age of Leo = x

So, The age of Kate = x - 4

Here, Twice Kate's age minus 3 is the same as Leo's age plus 9.

Hence, We can formulate;

⇒ 2 (x - 4) - 3 = x + 9

Solve for x as;

⇒ 2x - 8 - 3 = x + 9

⇒ 2x - x = 9 + 11

⇒ x = 20 years

Thus, The age of Leo = x

3. If we multiply both sides by  a  we get  a^{2} = ab .

4. If we then subtract  b^{2}  from both sides we would have  a^{2} - b^{2} = ab - b^{2} .

5. We can then factorise both sides to get  (a + b)(a - b) = b(a - b) .

6. Dividing both sides by  (a - b)  would give us  a + b = b .

7. Substituting back the values of  a = 1  and  b = 1  would give us that  1 + 1 = 1 .

The equation of the circular flower garden represented on the blueprint is (x-5)²+(y-15)² = 4

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Fencing encloses a rectangular backyard that measures 200 feet by 600 feet. A blueprint of the backyard is drawn on the coordinate

plane so that the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0).

A circular flower garden is dug to be exactly in the centre of the backyard, with a radius of 40 feet. This garden is represented of on the blueprint.

Since, the rectangle has vertices (0,0), (0, 30), (10, 30), and (10, 0) therefore, it will form a rectangle with width 10 units and height 30 units.

In this situation, the centre of the rectangle is at (5, 15) (Half of the width in the first coordinate and half of the height in the second one)

Since, we know that the equation of the circle is given by;

(x-a)²+(y-b)² = R²

Where, (a, b) is the centre point and R is the radius,

Therefore, the equation of the flower garden will be;

(x-5)²+(y-15)² = R²

Now, solving for R,

We know that the rectangular backyard width is 200 feet and this is represented with a rectangle in the blueprint with width 10 units

10 units = 200 ft

Therefore, 40 ft = 2 units

Therefore, The radius of 40 feet is represented with 2 units in the blueprint.

Now we replace R = 2 in the equation :

(x-5)²+(y-15)² = 2²

(x-5)²+(y-15)² = 4

Hence, the required equation is (x-5)²+(y-15)² = 4

We need to find the probability of selecting a heart and the coin landing on heads.

We know that there are 13 hearts in a standard deck of playing cards, and there are 52 cards total.

So, the probability of selecting a heart would be,

P1 = 13/52

P1 = 1/4

P1 = 0.25

We know that the probability of flipping a coin and landing on heads is 1/2

P2 = 1/2

P2 = 0.50

The probability of both occurring is the product of the two probabilities,

P = P1 * P2

P = 0.25 * 0.50

P =1.25

Step-by-step explanation:

The value is x=9, when the points are (x,1), (-3,7), (-5,9), (5,4).

The slope formula is defined as the formula used to calculate the steepness of a line and to determine how much it's inclined. To calculate the slope of the lines, we need the x and y coordinates of the points.

The formula to calculate slope is given as,

m = (y2 - y1)/(x2 - x1)

where m is the slope of the line,

x1, x2 are the coordinates of the x-axis,

y1 and y2 are the coordinates of the y-axis.

Consider the Points as A=(x,1),B=(-3,7),C=(-5,9),D=(5,4)

Now, take two points  C, D to know the m value:

Slope  = y₂ - y₁/ x₂-x₁

m1 = 4 - 9 / 5- [-5]

     = -5 / 5+5  = -5/10 = -1/2

m1 = -1/2

Consider the next two points A, B:

A(x, 1), B(-3,7)

Slope of AB m2 =  7- 1 / -3 - x  

m2= 6/-3-x

As AB  || CD, m2 = m1

6/-3-x=-1/2
