The total cost is D) $141

Step-by-step explanation:

To solve we can use the equation: [tex]y=25d+0.10m[/tex]

d= number of days  m= number of miles

We know both of these values so we can plug them in and solve.

y= 25(3) + 0.10(660)

y= 75 + 66

y = 141

Answer:

So solving for x,

X=3

Final answer:

After solving the equations, Mindy and Sean will have the same amount of money, which is $70, after 3 weeks.

Explanation:

The question is about finding after how many weeks Mindy and Sean would have the same amount of money and how much that amount would be. Let's denote the number of weeks as w. For Mindy, who starts with $55 and saves $5 per week, her amount of money as a function of weeks is 55 + 5w. For Sean, who starts with $100 and spends $10 every week, his amount of money as a function of weeks is 100 - 10w.

To find out after how many weeks they would have the same amount of money, set the two expressions equal to each other:

55 + 5w = 100 - 10w

Add 10w to both sides and subtract 55 from both sides to solve for w:

15w = 45

Therefore, w = 45 / 15 = 3

To find out how much money they would have, substitute w = 3 into one of the original equations:

Mindy: 55 + 5(3) = 70

So, after 3 weeks, both Mindy and Sean will have $70

Answer:

x = (4z -y)/(3 – y); y ≠ 3

Step-by-step explanation:

3x – xy = 4z - 5y     Factor

  x(3-y) = 4z - y        Divide each side by 3-y

        x = (4z -y)/(3 – y); y ≠ 3

x is undefined when y = 3, so we must include the condition that y ≠ 3.

Answer:

The second dealer is better.

Step-by-step explanation:

To figure this out we need to divide the price by the amount of milk. Lets do both at the same time.

3.8/2=   2.7/1.5=

3.8/2=1.9   2.7/1.5=1.8

The second dealer is better.

Price per unit is the cost of the sing unit or measure of goods or the service provided.The second vendor sells 1 liter of fresh milk at $1.80 which is $0.10 less than the first vendor. Therefore the second vendor gives the better deal.

Given information-

First vendor sells 2 liters for $3.80.

Second vendor sells 1.5 liters for $2.70.

Price per unit is the cost of the sing unit or measure of goods or the service provided.

Price per unit helps to compare the two product with there cost. The less will be the price per unit of a product the product will be more cheaper.

Price per unit is the ratio of the total cost to the number of units.

The vendor which provide more milk in less rate will be the better deal.

As first vendor sells 2 liters for $3.80. Thus the price of milk per liter is,

[tex]P_1=\dfrac{3.80}{2} \\P_1=1.90[/tex]

Hence the first vendor sells the 1 liter milk in $1.90.

As Second vendor sells 1.5 liters for $2.70. Thus the price of milk per liter is,

[tex]P_2=\dfrac{2.70}{1.5} \\P_2=1.80[/tex]

Hence the second vendor sells the 1 liter milk in $1.80.

Hence the second vendor sells 1 liter of fresh milk at $1.80 which is $0.10 less than the first vendor. Therefore the second vendor gives the better deal.

y = (x + 9)² + 9

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

given a parabola in standard form : ax² + bx + c : a ≠ 0

To find the diagonal of a door frame, use the Pythagorean theorem. Substitute the door's height and width into the formula, then find the square root of the sum. Round your answer to the nearest tenth.

To find the length of the diagonal of the door frame, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the long side, or in this case, the diagonal) is equal to the sum of the squares of the other two sides (height and width of the door).

So, the formula becomes: Diagonal = √((Height)^2 + (Width)^2)

Substitute the given values of the height and width into the equation: Diagonal = √((80 inches)^2 + (36 inches)^2) = √(6400 + 1296) = √7696

The square root of 7696 is about 87.7 inches. So, the length of the diagonal of the door frame, rounded to the nearest tenth, is 87.7 inches.

Answer:

ax²+ bx + c = 0

Step-by-step explanation

Multiplying (x+4) and (x−1) together (called Expanding) gets x2 + 3x − 4 :

expand vs factor quadratic

So (x+4) and (x−1) are factors of x2 + 3x − 4

Just to be sure, let us check:

(x+4)(x−1)  = x(x−1) + 4(x−1)

 = x2 − x + 4x − 4

 = x2 + 3x − 4 yes

Yes, (x+4) and (x−1) are definitely factors of x2 + 3x − 4

To factorise a quadratic equation, express it in the standard form ax² + bx + c = 0, identify coefficients a, b, and c, and then apply the quadratic formula.

To factorise quadratics in their simplest form, you need to express them in the standard quadratic form, which is ax² + bx + c = 0. For example, if you are given the equation x² + 4x - 21 = 0, you should identify a = 1, b = 4, and c = -21. Then you can apply the quadratic formula:

'x' equals minus ‘b’, plus-or-minus the square root of ‘b’ squared minus four ‘a’ ‘c’, all over two 'a' (x = [tex]\frac{-b \pm \sqrt{b^2- 4ac} }{2a}[/tex])

If you are given an equation like 3x +3 + x² + x = 24, first rearrange it into the standard quadratic form by combining like terms. Use the quadratic formula if you cannot factor the quadratic easily.

Keep in mind that the quadratic formula can only be used if the equation is a true quadratic with powers confined to the second, first, and zeroth (constant term). If other powers or roots are present, then alternative methods must be used.

Answer:

The jogging rate of Matthew is 5 mph.

Step-by-step explanation:

Let the jogging rate of Matthew be x mph.

It is given that his jogging rate was 25 mph slower than the rate when he was riding. So, the riding rate is (x+25) mph.

The distance between Matthew and his friend's house is 12 miles.

[tex]Speed=\frac{Distance}{Time}[/tex]

[tex]Time=\frac{Distance}{Speed}[/tex]

The time taken by Matthew in jogging is [tex]\frac{12}{x}[/tex] and the time taken by Matthew in riding is [tex]\frac{12}{x+25}[/tex].

It took him 2 hours longer to jog there than ride back.

[tex]\frac{12}{x}=\frac{12}{x+25}+2[/tex]

[tex]\frac{12}{x}-\frac{12}{x+25}=2[/tex]

[tex]\frac{12(x+25)-12x}{x(x+25)}=2[/tex]

[tex]12x+300-12x=2x(x+25)[/tex]

[tex]300=2x^2+50x[/tex]

[tex]0=2x^2+50x-300[/tex]

[tex]0=x^2+25x-150[/tex]

[tex]0=x^2+30x-5x-150[/tex]

[tex]0=(x+30)(x-5)[/tex]

Equate each factor equal to 0.

[tex]x=5,-30[/tex]

The speed cannot be negative, therefore the jogging rate of Matthew is 5 mph.

Step-by-step explanation:

Answer: A swimming pool that is 5/10 full.

Answer: [tex]F=15N[/tex]

Step-by-step explanation:

1. You know that the force acting on the object varies directly with the object's acceleration. Then, by definition, you have:

[tex]F=ka[/tex]

Where [tex]F[/tex] is the force acting on the object, [tex]a[/tex] is the object's acceleration and [tex]k[/tex] is the constant of proportionality.

2. Keeping this on mind, you can calculate the constant of proportionality by substituting [tex]F=18[/tex] and [tex]a=6[/tex] into the equation and solving for [tex]k[/tex]:

[tex]18=k6\\k=\frac{18}{6}\\k=3[/tex]

3. Now, you can calculate the force when the acceleration of the object becomes 5 m/s², as following:

[tex]F=3(5)\\F=15[/tex]

3. The result is:

[tex]F=15N[/tex]

The acceleration that an objects gains is given by the mass of the object.

Reason:

The given parameters are;

The acting force ∝ The acceleration of the object.

The acceleration given by an amount of force, F, of 18 N = 6 m/s²

Required:

The force acting on the object acceleration, a, is 5 m/s².

Solution:

According to Newton's Second Law of motion, we have;

F = m·a

Where;

m = The mass of the object

Therefore, we have;

[tex]Mass, \, m = \dfrac{F}{a}[/tex]

From the conditions, F = 18 N, when a = 6 m/s², we have, the mass of the

given object is given as follows;

[tex]Mass \ of \ the \ object, \, m = \dfrac{18 \, N}{6 \ m/s^2} = 3 \, kg[/tex]

The force acting when the the acceleration, a = 5 m/s², is therefore;

F = 3 kg × 5 m/s² = 15 N

If the acceleration of the object becomes 5 m/s² the force is 15 N.

The angle bisector divides a triangle into two similar triangles Option B) sometimes, specifically when the triangle is isosceles.

1. Isosceles Triangle: In an isosceles triangle, two sides are equal in length. When the angle bisector of the vertex angle is drawn, it also bisects the base, creating two congruent triangles (by the Angle Bisector Theorem). Congruent triangles are always similar, so in this case, the statement holds true.

2. Scalene Triangle: In a scalene triangle, none of the sides are equal. When you draw the angle bisector of one of the angles, it won't necessarily bisect any other side into two equal lengths. Hence, the resulting triangles formed by the angle bisector won't necessarily be similar.

So, the angle bisector divides the triangle into two similar triangles sometimes (when it's an isosceles triangle) but not always (when it's a scalene triangle).

Answer: 27-c =x

Step-by-step explanation:

We'll use c to represent the amount taken away (subtracted) and x to represent the amount left (the answer).

We begin with 27 balloon, and take away c amount to make x.

27-c =x

The number of balloons left after c balloons have popped from an initial number of 27 balloons can be represented by the mathematical expression 27 - c.

In order to determine the number of balloons that were left after some of them had popped, we can use a simple mathematical expression. If there were initially 27 balloons and c balloons popped, then the number of balloons left would be the initial number of balloons minus the number popped.

Mathematically, this can be represented by the expression: 27 - c.

The variable c is used to represent the number of balloons that popped during the party. By subtracting this from the total number of balloons, we're left with the number of balloons that survived the party.
