Answer:

[tex]2 \, \dfrac{4}{25} \textrm{ ft}[/tex]

Step-by-step explanation:

First, solve for how many feet Jason has dug after 40 minutes:

[tex]\dfrac{\dfrac{3}{5} \textrm{ ft}}{10 \textrm{ min}} \times 40 \, \textrm{min} = 2 \dfrac{2}{5} \, \textrm{ft}[/tex]

So, the hole he has dug is 2 2/5 ft deep.

Next, we can solve for how deep the hole will be after placing a plant in by simply multiplying 9/10 by the depth of the hole dug.

[tex]2\, \dfrac{2}{5} \times \dfrac{9}{10} = \dfrac{12}{5} \times \dfrac{9}{10} = \dfrac{6 \times 9}{5 \times 5} = \dfrac{54}{25} = 2 \, \dfrac{4}{25} \textrm{ ft}[/tex]

The price of each bag of popcorn and the price of each drink is $7.5 and $4 respectively.

Let the drinks be represented as d.

Let the popcorn be represented as p.

From the information, Xochitl went into a movie theater and bought 6 bags of popcorn and 4 drinks, costing a total of $65. Thus will be:

6p + 4d = 65

Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. This will be:

9p + 8d = 107.50

Equating the equation

6p + 4d = 65 ..... i

9p + 8d = 107.50 ..... ii

Multiply equation i by 8

Multiply equation ii by 4

48p + 32d = 520

36p + 32d = 430

12p = 90

Divide

p = 90/12

= 7.5

6p + 4d = 65 .

6(7.5) + 4d = 65

4d = 65 - 45

4d = 20

d = 20/4

drink = 5

Answer: y = 40deg, x = 80deg

Step-by-step explanation:

1. Because we see that there are parallel lines in the triangle to the left, we know that two of the angles of that triangle are 50deg

2. using the fact that triangles have a total of 180deg we get x = 80deg

To solve for y, we also know that there are two angles in that triangle which are the same, and one of them is y, therefore 2y + 100deg = 180deg, meaning 7 = 40deg

The solution of the simultaneous equations using target matrix are; x = 51/37 and y = 33/37

The target variable is defined as the variable whose values are modeled and predicted by other variables.

We are given the simultaneous equations as;

5x - y = 6

2x + 7y = 9

In matrix form, it is expressed as;

5 -1 6

2 7 9

row 2 = row 2 + row 1 * 7

This gives us;

37   0   51

Thus;

x = 51/37

Plugging in 51/37 for x in eq 1 gives;

5(51/37) - y = 6

Multiply through by 37 to get;

5*51 - 37y = 37*6

255 - 37y = 222

Carly can walk 1 mile in 264 seconds.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

Unit rate of Carly is given.

Unit rate of an object in terms of distance covered and time taken is actually the speed of the object.

The formula for speed is,

Speed = Distance / Time

Speed = 20 feet per second

Distance = 1 mile = 5280 feet

Time taken be t.

20 = 5280 / t

t = 5280 / 20

t = 264 seconds

Hence it will take 264 seconds for Carly to walk a mile.

The amount of 14 % of ethanol that needs to mixed is A = 36 gallons

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

14% ethanol fuel mixture should be mixed with 8 gal of 3% ethanol fuel mixture to get a mixture that is 12% ethanol

So , the equation is

A ( 14 % ) + ( 8 ) ( 3 % ) = ( A + 8 ) ( 12 % )

On simplifying , we get

14A + 24 = 12A + 96

Subtracting 12A on both sides , we get

2A + 24 = 96

Subtracting 24 on both sides , we get

2A = 72

Divide by 2 on both sides , we get

A = 36 gallons

Therefore , the value of A is 36 gallons

The linear equation that is represented in the table is:

y = 3*x + 2

A general linear equation can be written in the form:

y = m*x + b

Where m is the slope and b is the y-intercept.

First, notice that on the table we can see the point (0, 2), then the y-intercept of the linaer function is b = 2

Then we can write:

y = m*x + 2

Now we can use any other point on the table to find the value of the slope m.

Using the second point (1, 5),replacing the values we will get:

5 = m*1 + 2

Solving for m, we will get:

5 = m + 2

5 - 2 = m

A. The speed of the boat going against a current with a rate of x mph is (13 - x) mph.

B. The speed of the boat going with a current with a rate of x mph is (13 + x) mph.

Step-by-step explanation:

The shape that results from a plane passing through a cone that is perpendicular to the base is option B: Circle.

When a plane passes through a cone perpendicular to the base, it intersects the cone at a circle. This is because the plane is cutting the cone at a 90-degree angle to the base, and so it is cutting through the circular cross-section of the cone.

Therefore, If the plane were to be tilted or angled, the shape of the intersection would be an ellipse, which is a flattened circle. This is because an ellipse is the shape that results when a plane intersects a cone at an angle that is not perpendicular to the base.

Answer:

x = 20

y = 20

Step-by-step explanation:

In the given triangle, we can deduce that angle x is congruent to angle y using the Isosceles Triangle Theorem. Hence, we can construct the equation xº = yº.

We also know that the measures of the interior angles of a triangle add to 180º. Hence, we can construct the equation xº + yº + 140º = 180º.

We now have a system of equations, and since we already have an identity for xº (and also for yº), we can solve the system using the substitution method.

xº + yº + 140º = 180º

↓ substituting xº for yº

xº + xº + 140º = 180º

↓ subtraction 140º from both sides

2xº = 40º

↓ dividing both sides by 2

xº = 20º

↓ removing degree sign from both sides

x = 20

Now that we have solved for x, we have also essentially solved for y, as plugging this x-value into the equation xº = yº will just yield:

20 = y

y = 20

2) The values of S and T for which the equation Sx + 81 = -24x + T have infinitely many solutions is S = 24 and T = -81

c. S = 24 and T = -81

An equation is a statement of equivalence of two expressions.

The specified equation is presented as follows;

S·x + 81 = -24·x + T

The equation will have infinitely many solutions when both sides of the equation refer to the the sam line

The power of x on both sides of the equation is one, therefore, both expressions on the left and right side of the equation refer to linear relationships

The graph of two lines are the same if they have the same slope and the same y-intercept.

The slope of the expression on the left = S

The y-intercept of the expression on the left = 81

The slope of the expression on the right = -24

The y-intercept of the expression on the right = T

When both sides refer to the same line, we get;

S = -24, and T = 81

Therefore, both sides of the equation refers to the same line and therefore have infinitely many solutions when S = -24 and T = 81.
