Answer:

The heat added to the system.

Step-by-step explanation:

Answer: I took a test, the answers C.

Step-by-step explanation:

We are given:  The cost of one flower bouquet =$ b.

The cost of one vase = $ v.

First florist bought: 2 flower bouquets and 2 vases.

2 *  cost of one flower bouquet + 2*cost of one vase = Total cost.

2b +2v = 12.50   ------------------------equation (1).

Second florist bought: 8 flower bouquets and 2 vases.

8 *  cost of one flower bouquet + 2*cost of one vase = Total cost.

8b +2v = 29.00    ------------------------equation (2).

Therefore, system of equations  we got is 2b +2v = 12.50  and 8b +2v = 29.00.

Subtracting first equation from second equation.

8b +2v = 29.00

-(2b +2v = 12.50)

____________________

6b = 16.50.

Dividing both sides by 6, we get.

b= 2.75.

Plugging b=2.75 in first equation we get

2(2.75) +2v = 12.50

5.50 +2v = 12.50

Subtracting 5.50 from both sides, we get

5.50-5.50 +2v = 12.50-5.50

2v = 7

Dividing both sides by 2, we get

v =3.50.

Therefore, cost of one flower bouquet is $2.75 and cost of one vase is $3.50.

Answer:

$12 per hour

Step-by-step explanation:

To solve how much did Robin earned per hour you just have to do a simple equation, we know that he worked 9 weeks, and that each week he worked 40 hours, so you equation would look like this:

[tex]Income=(wageperhour)*(hours worked)[/tex]

The hours worked is just a math done by multiplying the weeks worked by the hours worked per week that would be:

[tex]Hours worked=Hours worked per week*weeks\\Hours worked=(40 hours)*(9 weeks)\\Hours worked=360 hours[/tex]

So now we just put the data into our equation

[tex]Income=(wageperhour)*(hours worked)\\$4320=(wageperhour)*(360)\\wage per hour=4320/360\\ Wage per hour= 12[/tex]

The time taken by Graham is approximately 4/127 hours, which is about 0.0315 hours or roughly 1 minute and 53 seconds, to drive one mile.

To find out how many hours Graham took to drive one mile,

simply divide the total time (1 1/3 hours) by the total distance (42 1/3 miles):

Total time = 1 1/3 hours

                 = 4/3 hours

Total distance = 42 1/3 miles

                        = 127/3 miles

Now, divide the total time by the total distance:

Time per mile

= (Total time) / (Total distance)

= (4/3 hours) / (127/3 miles)

Now, when you divide by a fraction, you can multiply by its reciprocal:

Time per mile

= (4/3 hours) × (3/127 miles)

= (4/127) hours per mile

Therefore, the total time Graham took approximately 4/127 hours to drive one mile.

The approximate maximum height that the rocket reaches is 25 feet.

Function is a type of relation, or rule, that maps one input to specific single output. Given two function f(x) and g(x) can be written as f(X) + g(X). It is the sum of two functions similar to the addition of any two polynomial functions

+ x -7.

We are given that;

Initial velocity of the rocket= 40 feet per second.

The height of the rocket after t seconds is given by the formula:

h(t) = -16t^2 + v0t + h0

where v0 is the initial velocity (in feet per second) and h0 is the initial height (in feet).

Since the rocket is launched from the ground, its initial height is h0 = 0. Substituting this and v0 = 40 into the formula, we get:

h(t) = -16t^2 + 40t

To find the approximate maximum height that the rocket reaches, we need to find the vertex of the parabolic function h(t) = -16t^2 + 40t. The vertex occurs at the value of t that maximizes the height, which is given by:

t = -b/2a

where a = -16 and b = 40 are the coefficients of the quadratic function. Substituting these values into the formula, we get:

t = -40/(2*(-16)) = 1.25

Therefore, the rocket reaches its maximum height after approximately 1.25 seconds. To find the maximum height, we can substitute this value of t into the formula for h(t):

h(1.25) = -16(1.25)^2 + 40(1.25) ≈ 25 feet

Therefore, by the given function answer will be 25 feet.

Answer:

Circumference of the circle to the nearest hundredth is, 69.08 cm

Step-by-step explanation:

Circumference(C) of the circle is given by:

[tex]C = 2\pi r[/tex]            .....[1]

where,

r is the radius of the circle.

As per the statement:

middle of circle is 11 cm

⇒[tex]r = 11 cm[/tex]

use [tex]\pi = 3.14[/tex]

Substitute these in [1] we have;

[tex]C = 2 \cdot 3.14 \cdot 11 = 69.08 cm[/tex]

Therefore, the circumference of the circle to the nearest hundredth is, 69.08 cm

The circumference of a circle with a radius of 11cm is 69.08cm, rounded to the nearest hundredth.

To estimate the circumference of a circle using π (Pi), you need to know the diameter of the circle which is twice the radius. Since you've mentioned the circle has a middle (radius) of 11cm, the diameter is 22cm. The formula for the circumference of a circle is C = πd, where d is the diameter.

Using the given approximation of Pi (π = 3.14), you can calculate:

C = 3.14 × 22cm

C = 69.08cm

Therefore, the estimated circumference is 69.08cm, which can be rounded to the nearest hundredth as 69.08cm.

The area of Dominic's trapezoid-shaped bench seat is 11.25 square feet. This is calculated using the trapezoid area formula with given bases of 5 and 4 feet and a height of 2.5 feet.

To find the area of the seat of Dominic's bench, which is in the shape of a trapezoid, we use the formula for the area of a trapezoid:

Area = 1/2 × (Base1 + Base2) × Height

In this case:

Substitute these values into the formula:

Area = 1/2 × (5 + 4) × 2.5

Area = 1/2 × 9 × 2.5

Area = 4.5 × 2.5

Area = 11.25 square feet

Thus, the area of the trapezoid-shaped seat is 11.25 square feet.

Step-by-step explanation:

Answer:

The correct answer is A).

Step-by-step explanation:

He have the quadratic functions f(x) = 16x²-240x+896. The first step should be to check if the coefficients 240 and 896 are divisible by 16, which is true. Then, extracting 16 as common factor we have

f(x) = 16(x²-15x+56).

Now we can use directly the formula to find the roots of a quadratic equation, or a more efficient way in terms of calculations. We must find to numbers such that their product is +56 and their addition or subtraction is -15. It is not difficult to check that -7 and -8 fulfill those conditions. Hence,

f(x) = 16(x²-15x+56)= 16(x-7)(x-8).

Therefore, the solutions are x=8 and x=7.

Here are the steps to follow:

The LCD of [tex]\( \frac{4}{6} \)[/tex] and [tex]\( \frac{5}{7} \)[/tex] is [tex]42[/tex]. This is because [tex]42[/tex] is the smallest number that both [tex]6[/tex] and [tex]7[/tex] divide into evenly, ensuring that [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] can be expressed with a common denominator of [tex]42.[/tex]

1. Convert [tex]\( 4 \frac{1}{6}[/tex]  to an improper fraction:

[tex]\[ 4 \frac{1}{6} = \frac{4 \times 6 + 1}{6} = \frac{24 + 1}{6} = \frac{25}{6} \][/tex]

2. Convert [tex]\( 5 \frac{4}{7} \)[/tex] to an improper fraction:

[tex]\[ 5 \frac{4}{7} = \frac{5 \times 7 + 4}{7} = \frac{35 + 4}{7} = \frac{39}{7} \][/tex]

Now, the fractions [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] need to have a common denominator to find the LCD.

Finding the Least Common Denominator (LCD)

To find the LCD, we need to determine the least common multiple (LCM) of the denominators [tex]6[/tex] and [tex]7[/tex]

The prime factorization of [tex]6[/tex] is [tex]\( 2 \times 3 \).[/tex]

The prime factorization of [tex]7[/tex] is [tex]\( 7 \).[/tex]

The LCM of [tex]6[/tex] and [tex]7[/tex] is [tex]\( 6 \times 7 = 42 \).[/tex]

Convert both fractions to have a denominator of [tex]42[/tex]

[tex]\[ \frac{25}{6} \times \frac{7}{7} = \frac{175}{42} \][/tex]

[tex]\[ \frac{39}{7} \times \frac{6}{6} = \frac{234}{42} \][/tex]

Now, [tex]\( \frac{25}{6} \) converts to \( \frac{175}{42} \) and \( \frac{39}{7} \) converts to \( \frac{234}{42} \).[/tex]

Final answer:

The volume of a cylinder with a radius of 4 units and a height of 8 units is 401.92 cubic units, calculated using the formula V = πr²h and rounding to the nearest hundredth.

Explanation:

Calculating the Volume of a Cylinder

To find the volume of a cylinder, we can use the formula V = πr²h, where 'V' represents the volume, 'r' is the radius, and 'h' is the height of the cylinder. Since you have provided that the radius (r) is 4 units and the height (x) is 8 units, we can substitute these values into the formula as follows:

V = 3.14 × (4 units)² × 8 units

First, we calculate the radius squared (4 units)²:

(4 units)² = 16 units²

Now we multiply this by the height and π as given:

V = 3.14 × 16 units² × 8 units

V = 3.14 × 128 units³

V = 401.92 units³

Therefore, the volume of the cylinder is 401.92 cubic units, rounded to the nearest hundredth.

If a rectangular prism has a lenght of 8 inches and a width of 7 inches. The lateral area is 150 square inches then the height of the rectangular prism is 5 inches.

To find the height of the rectangular prism, we'll first find the formula for the lateral area of a rectangular prism and then solve for the height using the given lateral area.

The lateral area of a rectangular prism is given by the formula:

[tex]\[ \text{Lateral Area} = 2 \times (\text{Length} \times \text{Height} + \text{Width} \times \text{Height}) \][/tex]

Given that the length is 8 inches, the width is 7 inches, and the lateral area is 150 square inches, we can substitute these values into the formula and solve for the height:

[tex]\[ 150 = 2 \times (8 \times \text{Height} + 7 \times \text{Height}) \][/tex]

[tex]\[ 150 = 2 \times (8\text{Height} + 7\text{Height}) \][/tex]

[tex]\[ 150 = 2 \times 15\text{Height} \][/tex]

Divide both sides by 2:

[tex]\[ 75 = 15\text{Height} \][/tex]

Now, solve for the height:

[tex]\[ \text{Height} = \frac{75}{15} \][/tex]

[tex]\[ \text{Height} = 5 \text{ inches} \][/tex]

So, the height of the rectangular prism is 5 inches.
