Answer: The answer is 340

Step-by-step explanation:

You have to first find the area of the swimming pool 60 then you subtract it by the backyard 400 so you would get 340.

First, you have to find the area of the rectangular swimming pool (A1), which has <span>10 feet long and 6 feet wide. The area of a rectangle is:

 A=A1=LxW

 L=10 ft
 W=6 ft

 When you substitute these values into the formula, you obtain:
</span>
 A1=LxW
 A1=(10 ft)(6ft)
 A1=60 ft²

 The area of the Andrea’s backyard (A2) is 400 ft², therefore, the<span> area of Andrea’s backyard, not including the swimming pool (A3), is:

 A3=A2-A1
 A3=400 ft</span>²-60 ft²
 A3=340 ft²
<span>
 What is the area of Andrea’s backyard, not including the swimming pool?

 The answer is: T</span>he area of Andrea’s backyard, not including the swimming pool, is 340 feet²

What is Mia's error? 83 + n = 110<br> 83 + 83 + n = 110 + 83 n=193
Tanya [424]

Answer:

She added 83 instead of subtracting

Step-by-step explanation:

83 + n = 110

We want to do the opposite to n

We are adding 83 to n.  The opposite is subtract 83

83+n-83 = 110-83

n =27

Mia

83 + n = 110

83 + 83 + n = 110 + 83

163+n=193

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3. 00 0. 50 m = 9. 5
Sliva [168]

The statement, which shows the meaning of the taxi driver’s equation for the mileage and fee formula are statement B and E.

<h3>What is linear equation or formula?</h3>

Linear equation or formula is the equation in which the highest power of the unknown variable is one.

Given information-

The formula equation for the mileage is,

3.00+0.50m=9.50

In the above formula the term <em>m </em>represents the number of miles traveled.

This formula written by the taxi driver shows the relation between the mileage and fee for his last customer. Using this expression the number of miles can be calculated as,

3.00+0.50m=9.50

Subtract with 3 both the sides,

0.50m=9.50-3.00\\0.50m=6.50

Divide by number 0.5 both the sides,

m=\dfrac{6.5}{0.5}\\m=13

Thus, his last costumer traveled 13 miles.

The 13 times 0.5 plus $3 is equal to the $9.50 which means nine dollars and fifty cents. Thus the option B is the correct option.

The number of miles traveled by customer is 13 miles. 13 miles of 50 cent  is equal to $6.5. If we add three dollars in it the result will be equal to the nine dollars and fifty cents. Thus the option E is correct.

Hence, the statement, which shows the meaning of the driver’s equation, are,

  • B) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
  • E) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Evan was broke didn't he got his weekly allowance but because he has a hard time saving money he spent half his weekly allowance
grin007 [14]

Answer:

$16

Step-by-step explanation:

Let his weekly allowance = x

Amount spent playing golf = x / 2

Amount earned for cleaning car = $4

Final amount at hand = $12

Mathematically ;

x/2 + 4 = 12

x/2 = 12 - 4

x/2 = 8

x = 2 * 8

x = $16

Weekly allowance = $16

Write an Equation using the following arithmetic sequence: 5, _____, ______, 32
Shalnov [3]

Answer:

The sequence is:

5, 14, 23, 32

Step-by-step explanation:

We know that an Arithmetic sequence with a₁ and the commo difference 'd' has the nth term such as:

aₙ = a₁ + (n-1)d

Given the arithmetic sequence

5, _____, ______, 32

here:

a₁ = 5

n = 4

aₙ

so substituting a₁ = 5, n = 4 and aₙ = 32 in the nth term

aₙ = a₁ + (n-1)d

32 = 5 + (4-1)d

32 = 5 + 3d

3d = 32-5

3d = 27

divide both sides by 3

3d/3 = 27/3

d = 9

Therefore, the common difference: d = 9

Determining the 2nd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 2, a₁ = 5, d = 9

a₂ = 5 + (2-1)9

a₂ = 5 + 1(9)

a₂ = 5 + 9

a₂ = 14

Determining the 3rd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 3, a₁ = 5, d = 9

a₃ = 5 + (3-1)9

a₃ = 5 + 2(9)

a₃ = 5 + 18

a₃ = 23

Thus, the sequence becomes:

5, 14, 23, 32
