If Guy walks from his house to school and back, how far does he walk.

Answers

Answer:

total distance = 1 miles

Step-by-step explanation:

According to the information given below from the picture, the distance from the guy's house to the school is given as 5/10 miles.

5/10 miles can still be reduced to the lowest fraction as 1/2 miles.

Since he works to and fro from his house to school and school to house, The distance he covered will be the sum of the distance from house to school and school to house .

Distance from house to school = 1/2 miles

Distance from school to house = 1/2 miles

The total distance he covered = 1/2 miles + 1/2 miles

total distance = 1 miles

5/10 plus 5/10 equals 10/10 which equals 1.

I need help with 6-8

Answers

Answer:

6. y² = 169x

7. y² = 12x

8. $y^(2) = (1)/(2)x$

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by

(y - α)² = 4a(x - β)

Where, (α,β) is the vertex of the function and a is the distance from vertex to its focus.

6. Here, (α,β) ≡ (0,0) and a point on the equation is (1,13)

So, the equation will be y² = 4ax

⇒ 13² = 4a(1)

⇒ 4a = 169

Therefore, the original equation will be y² = 169x (Answer)

7. Here also the vertex is (0,0) and a point on the equation is (3,-6),

So, (-6)² = 4a(3)

⇒ 4a = 12

So, the equation is y² = 12x (Answer)

8. Here also the vertex is (0,0) and a point on the equation is ( $(1)/(2),(1)/(2)$ ),

So, $((1)/(2))^(2) = 4a((1)/(2))$

⇒ $4a = (1)/(2)$

So, the equation is $y^(2) = (1)/(2)x$ (Answer)

Find the area of a regular pentagon with an apothem of 11 units. *364 square units
O 440 square units
516 square units
O 166 square units

Answers

Answer:

440 square units

Step-by-step explanation:

We can find half of a side of the pentagon with the expression

$tan(36\°)=(s_(half) )/(11)$

Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.

$s_(half) \approx 8$

Therefore, half of a side is 8 units long, which means each side measures 16 units.

Now, the area of a penthagon is defined by

$A=(p * a)/(2)$

Where $p$ is the perimeter and $a$ is the apothem. Where the perimeter is the sum of all sides, which is 80 units.

$A= (80 * 11)/(2) =440 \ u^(2)$

Therefore, the right answer is the second choice.

Jill says that 12.6666666 is less than 12.63 explain Her error

Answers

Look at the last number in the decimal.

12.66
12.63

Compare 6 and 3. 6 is larger so therefore 12.6666666 is larger. (You also need to compare the tenths place too, but these happen to have the same tenths place, .6.

Maxwell bought a new pair of skis for $350. He put $110 down and received a students discount of $30. His mother gave him 1/2 of the balance for his birthday. Which of these expressions could be used to find the amount Maxwell still owes on the skis?350 - 110 + 30 ÷ 2
350 - (110 - 30) ÷ 2
[350 - (110 - 30) ÷ 2]
[350 - (110 - 30)] ÷ 2

Answers

The expression used to find the amount Maxwell still owes on the skis is [350 - (110 + 30) ÷ 2]

What is an expression?

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Given that, Maxwell bought a new pair of skis for $350. He put $110 down and received a students discount of $30. His mother gave him 1/2 of the balance for his birthday,

We need to find the expression that can be used to find the amount Maxwell still owes on the skis,

So, the total amount of skis = $350, he put down $110 also got $30 discount,

So, the amount = 350 - (110+30) also, his mother gave him 1/2 of the balance for his birthday.

So, the final amount is 350 - (110 + 30) ÷ 2

Hence, the expression used to find the amount Maxwell still owes on the skis is [350 - (110 + 30) ÷ 2]
