Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Answer:

779.352 ft^2

Step-by-step explanation:

Given data

Diameter of circular garden= 16ft

Radius of garden= 16/2= 8ft

Length of side of square pond= 5ft

Area of circular garden= πr^2

A=3.142*16^2

A= 3.142*256

A=804.352 ft^2

Area of square pond

A= L^2

A= 5^2

A= 25ft

Hence the area that remains

=Area of circular garden- Area of square pond

=804.352- 25

= 779.352 ft^2

Step-by-step explanation:

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Step-by-step explanation:

135 : 32 = 4 ( 7)

Kết quả:  

135 /32

= 4  7 /32

Answer:

[tex]4\frac{7}{32}[/tex]

Step-by-step explanation:

Given the mixed numbers:

[tex]1\frac{1}{4}[/tex],[tex]1\frac{1}{2}[/tex],[tex]2\frac{1}{4}[/tex]

First, we need to convert them into improper fractions of the denominator of 4.

1 1/4 = 5/4

1 2/4 = 6/4

2 1/4 = 9/4

So we multiply 1 1/4 x 1 2/4 x 2 1/4 which gets us 4 7/32

Step-by-step explanation:

Given

[tex]18e^2f^3-12e^2f[/tex]

Required

Factorize:

[tex]18e^2f^3-12e^2f[/tex]

Express 18 as 6 * 3 and 12 as 6 * 2

[tex]18e^2f^3-12e^2f = 6*3e^2f^3-6*2e^2f[/tex]

Factor out 6

[tex]18e^2f^3-12e^2f = 6(3e^2f^3-2e^2f)[/tex]

Factor out [tex]e^2[/tex]

[tex]18e^2f^3-12e^2f = 6e^2(3f^3-2f)[/tex]

Factor out f

[tex]18e^2f^3-12e^2f = 6e^2f(3f^2-2)[/tex]

Answer:

Step-by-step explanation:

The number of marble left if Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends, is 3.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends,

Calculate the number of marble left as shown below,

The number of marble left = Reminder of (total number of marble / 8)

The number of marble left = Reminder of(75 / 8)

The number of marble left = 3

Thus, the number of marble left is 3.

Answer:

(45,9), (50, 14)

Step-by-step explanation:

the y-axis' pattern is subtract 2 and add 5.

the x-axis' pattern is add 7 then add 5.

So we get (45, 9) and (50, 14)

Answer:

no, they are equal. we know this because when reducing both they are equal.

Step-by-step explanation:

first find the least common denominator

that's 3

reduce fractions until the denominator is both 3

we get 2/3 and 2/3. the proportions are equal.

If salary average of 4 players is making $200,000/yr, what's the total payroll?  It should be $200K x 4 or $800,000.

Now if you add in that 5th player at $400,000 what is the total payroll of all 5 players?  It should be $800,000 + $400,000 = 1,200,000.  From there you can find the average of the 5 players by dividing!

Answer:The answer is going to be 3 and this is how we came to that determination:

We are to subtract 3 times the number from 7 times the number and have it equal 12. So here is the the mathematical sentence to help us get the answer:

7X-3X=12 ; now we are going to subtract the 3 from the 7 on the left hand side of the equal sign:

4X=12 ; now we will divide each side of the equal sign by 4:

4X/4=12/4 and get X =3 ; to prove 3 is the number we are looking for, we will substitute it for X in our original sentence:

7(3)-3(3)=12

21–9=12

12=12

3 is our answer.

Step-by-step explanation:

Answer:

11 [tex]\frac{3}{8}[/tex] miles.

Step-by-step explanation:

To find how many miles Brandon rode, we can create an equation in slope-intercept form: y = mx + b

$2.25 is the flat fee, or the unchanging variable. This is our y-intercept, or b.

$0.40 is the changing variable, as it changes value depending on the amount of miles ridden. This is our slope, or m.

We know Brandon spent $6.80 on the cab ride. So, this is our y.

We get the equation: 6.80 = 0.40x + 2.25.

To solve, first subtract 2.25 from both sides of the equation:

6.80 - 2.25 = 0.40x + 2.25 - 2.25

We get: 4.55 = 0.40x

Now, just divide by 0.40 on both sides:

4.55 ÷ 0.40 = 0.40x ÷ 0.40

We get: 11.375 = x

So, Brandon rode for 11.375 miles. When converted to a mixed number, we get 11 [tex]\frac{3}{8}[/tex] .

Answer:

x = 20

Step-by-step explanation:

4(x + 7) - 5x + 2 = 10

open the parenthesis

4 * x + 4 * 7 - 5x + 2 = 10

4x + 28 - 5x + 2 = 10

combine like terms

-x + 30 = 10

subtract 30 from both sides of the equation

-x + 30 - 30 = 10 - 30

-x = 10 - 30

-x = -20

mutiply the equation by -1

-1 * -x = -20 * -1

x = 20

The answer should be 120
