Sarah mowed 3 lawns in 9 hours what is her rate of mowing in hours per lawn?

Answers

Answer 1

Answer:

Sarah mowed 1 lawn in 3 hours

Step-by-step explanation:

3 lawns divided by 3 is 1 lawn

9 hours divided by 3 is 3 hours

Answer 2

Answer:

See below:

Step-by-step explanation:

So we know that she moves 3 lawns in 9 hours, to find how much time she takes per lawn we can divide both sides by three to get our number. We can do this due to the reason below:

[tex]\frac{3}{9}=3:9[/tex]

Due to this, we can simplify both sides by 3 and get our rate of 1 lawn per 3 hours.

Have a nice day and feel free to ask me if you need more help :D

What is an arithmetic operation?

Addition, subtraction, multiplication, and division of two or even more integers are the four basic mathematical operations. Included among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given data provided in the question,

3 dozen = 12 × 3 = 36 cookies.

2 cups of sugar are required to make 36 cookies

Let x cup of sugar is required to make 24 cookies.

El primer término de una progresión geométrica es 3 y el séptimo 12 288. Hallar la suma de los siete términos.

Answers

Answer:

16383

Step-by-step explanation:

El primer término de la progresión geométrica es 3 y lo llamaremos [tex]a[/tex].

Se tiene que una progresión geométrica es de la forma:

[tex]a, ar, ar^2, ar^3, ar^4, \cdot \cdot \cdot[/tex]

Donde [tex]r \neq 0[/tex] y es la proporción es común. Por lo tanto si el séptimo número de la sucesión es 12.288 este se puede re-escribir como:

[tex]ar^6 = 12.288[/tex]

Si se resuelve la ecuación para hallar [tex]r[/tex] se tiene

[tex]r = \sqrt[6]{\frac{12.288}{a} } = \sqrt[6]{\frac{12.288}{3} } = \sqrt[6]{ 4096} = 4[/tex]

Ahora se halla cada número de la progresión geométrica entre 1 y 7 para finalmente sumarlos

[tex]ar^0+ar^1+ar^2+ar^3+ar^4+ar^5+ar^6[/tex]

[tex]3+12+48+192+768+3072+12288[/tex] = 16383

Por lo tanto la sumatoria de los primeros [tex]7[/tex] términos de la sucesión son 16383

There are 25 students in a class, and 6 of them will be chosen to go on a field
trip. How many ways can these students be chosen?

Answers

Answer: 150 ways.

Explanation: This question deals with a combination. To find the total number of ways these students may be arranged in a field trip, assuming that the combination does not repeat (there can only be one of each student in a given group of 6), one must simply multiply the number of students total, 25, by the number of students allowed in a group, which is 6. Therefore, 25 • 6 = 150, which gives us our answer.

How much money was invested at 5% annual simple interest for 4 years to earn $2870?

Answers

Answer:

Principal (amount invested) = $14,350

Step-by-step explanation:

Given the simple interest amount of $2,870 earned in 4 years at 5% interest rate:

In order to find the principal amount that was invested, we could use the simple interest formula and isolate the variable, P, algebraically.

I = P × r × t

where:

I = interest earned = $2,870

P  = principal amount invested = ?

r  = interest rate = 5% or 0.05

t = time = 4

Divide both sides by (r × t ) to isolate P :

[tex]\displaystyle\mathsf{\frac{I}{(r\:\times\:t)}\:=\:\frac{P\:\times\:r\:\times\:t}{(r\:\times\:t)}}[/tex]

[tex]\displaystyle\mathsf{P\:=\frac{I}{(r\:\times\:t)}}[/tex]

Substitute the given values into the formula for P:

[tex]\displaystyle\mathsf{P\:=\frac{I}{(r\:\times\:t)}\:=\:\frac{2870}{0.05\:\times\:4}}[/tex]

[tex]\displaystyle\mathsf{P\:=\frac{2870}{0.20}=14,350}[/tex]

Therefore, the principal amount invested is $14,350.

Answer: Im not really sure if this is correct but it's what I put so I hope it is. If it's incorrect please let me know.

Step-by-step explanation:

We first need to find its mass and volume.

Mass: 8.05

Volume: Turn 3 feet into inches: 36

36in × 1.5in × 5.5in =297

Density : 8.05lb ÷ 297 cubic inches = 0.027 cubic inches

consider h(x)=x^2+8+15. identify its vertex and y-intercept.

Answers

Answer:

Vertex: (-4, -1)

Y-intercept: (0, 15)

Step-by-step explanation:

Given the quaratic function, h(x) = x² + 8x + 15:

In order to determine the vertex of the given function, we can use the formula, [tex][x = \frac{-b}{2a}, h(\frac{-b}{2a})][/tex].

Use the equation:  [tex][x = \frac{-b}{2a}, h(\frac{-b}{2a})][/tex]

In the quadratic function, h(x) = x² + 8x + 15, where:

a = 1, b = 8, and c = 15:

Substitute the given values for a and b into the equation to solve for the x-coordinate of the vertex.

[tex]x = \frac{-b}{2a}[/tex]

[tex]x = \frac{-8}{2(1)}[/tex]

x = -4

Subsitute the value of the x-coordinate into the given function to solve for the y-coordinate of the vertex:

h(x) = x² + 8x + 15

h(-4) = (-4)² + 8(-4) + 15

h(-4) = 16 - 32 + 15

h(-4) = -1

Therefore, the vertex of the given function is (-4, -1).

Solve for the Y-intercept:

The y-intercept is the point on the graph where it crosse the y-axis. In order to find the y-intercept of the function, set x = 0, and solve for the y-intercept:

h(x) = x² + 8x + 15

h(0) = (0)² + 8(0) + 15

h(0) = 0 + 0 + 15

h(0) = 15

Therefore, the y-intercept of the quadratic function is (0, 15).
