Answer and Step-by-step explanation:

We are told that AB is equal to 3x + 1.

BC is then half of AB, or [tex]\frac{3x+1}{2}[/tex].

AC is then 4 less than BC, or [tex](\frac{3x+1}{2} ) - 4[/tex]

To find the perimeter, we add all of these together.

3x + 3x/2 + 3x/2 = 6x

1 + 1/2 + (1/2 - 4) = -2

The final answer is 6x - 2.

Answer:

(a) p = 7

Step-by-step explanation:

The given parameters are;

p, (p - 5), (p - 2), (p - 3), and (2·p - 5) is 5.84

(a) Therefore we have;

The mean of the numbers = (p + (p - 5) + (p - 2) + (p - 3) + (2·p - 5))/5 = (6·p - 15)/5

The mean of the numbers = (6·p - 15)/5 = 6/5·p - 3

Using an online tool, we have;

The variance = (p - (6/5·p - 3))² + ((p - 5) - (6/5·p - 3))² + ((p - 2) - (6/5·p - 3))² + ((p - 3) - (6/5·p - 3))² + ((2·p - 5) - (6/5·p - 3))²/5 = 4/25·p² - 4/5·p + 18/5 = 5.84

Therefore, we have;

4/25·p² - 4/5·p + 18/5 = 5.84

4/25·p² - 4/5·p + 18/5 - 5.84 = 0

4/25·p² - 4/5·p - 2.24 = 0

Using the quadratic formula, we have;

p = (4/5 ± √((4/5)² - 4× 4/25×(-2.24)))/(2 × 4/25)

Which gives;

p = 7, or p = -2

Given that the numbers are positive, we have the only solution as p = 7

Answer:

The average of the 10 numbers is 195

Step-by-step explanation:

The average of a set of numbers is the sum of the numbers dividing by their number

∵ The average of 60 numbers is 55

∴ The average = 55

∴ The number = 60

→ Substitute them in the rule above to find the sum of the numbers

∵ 55 = The sum ÷ 60

→ Multiply each side by 60

∴ 3300 = The sum

∴ The sum of the 60 numbers = 3300

∵ 10 more numbers are included

∵ The average of  70 numbers become 75

∴ The average = 75

∴ The number = 70

→ Substitute them in the rule above to find the sum of the numbers

∵ 75 = The sum ÷ 70

→ Multiply each side by 70

∴ 5250 = The sum

∴ The sum of the 70 numbers = 5250

∵ The sum of the 10 numbers that added is the difference between

   the sums of the 60 and 70 numbers

∵ The difference between the sums = 5250 - 3300

∴ The difference between the sums = 1950

→ To find the average of them divide their sum by 10

∵ The average of the 10 numbers = 1950 ÷ 10

∴  The average of the 10 numbers = 195

Answer:

senior ticket = $10     child's ticket = $8

Step-by-step explanation:

s = senior ticket

c = child's ticket

We need to write 2 equations, and we have 2 unknowns, s and c.

3s + 5c = $70

12s + 12c = $216

First solve for s using the first equation.

3s + 5c = 70    Subtract 5c from each side

3s + 5c - 5c = 70 - 5c

3s =  70 - 5c     Divide each side by 3

3s/3 =  (70 - 5c)/3

s = [tex]\frac{70 - 5c}{3}[/tex]

Now plug in s into the second equation.

12s + 12c = 216

12([tex]\frac{70 - 5c}{3}[/tex]) + 12c = 216

[tex]\frac{12}{3}[/tex] (70 - 5c) + 12c = 216

4 (70 - 5c) + 12c = 216

280 - 20c + 12c = 216

280 - 8c = 216  Add 8c to each side

280 - 8c + 8c = 216 + 8c

280 = 216 + 8c   Subtract 216 from each side.

280 - 216 = 216 - 216 + 8c

280 - 216 = 8c

64 = 8c   Divide each side by 8

64/8 = 8c/8

64/8 = c

8 = c

Now plug c into the first equation and solve for s.

3s + 5c = 70

3s + 5(8) = 70

3s + 40 = 70    Subtract 40 from each side.

3s + 40 - 40 = 70 - 40

3s = 70 - 40

3s = 30  Divide each side by 3

3s/3 = 30/3

s = 30/3

s = 10

So a senior ticket costs $10 and a child's ticket costs $8.

Step-by-step explanation:

To find the distance travelled, you first have to find the circumference. After all, that is the part which actually touches the ground in the first place. The formula for the circumference is 2πr = C, where π=3.14, r is the radius (or half diameter). As such, we can plug in the values:

2*3.14*(26/2)=C -> 6.28*13=C -> 81.64 in = C

Step-by-step explanation:

Commutative law under addition says- p + q = q + p. Commutative law under multiplication says p x q = q x p. Note- Rational numbers, integers and whole numbers are commutative under addition and multiplication. Rational numbers, integers and whole numbers are non commutative under subtraction and division.

Answer:

Malike can use the boat for 3 hours.

Step-by-step explanation:

$2.50 for renting the boat plus $1.50 per hour. 3 hours x $1.50 = $4.50 + the $2.50 = $7 flat

Malike can use the boat for 3 hours without spending more than $7.00

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now it is given that,

Fixed charge of boat = $2.50

Charge per hour = $1.50

Now let t be the total hours use by Malike.

Total charge in t hour = 1.50t

Total spending on boat = 2.50 + 1.50t

Since. She wants to spend not more than $7.00

⇒ 2.50 + 1.50t ≤ 7

Subtracting 2.5 both the side we get,

1.50t  ≤ 7 - 2.5

⇒  1.50t  ≤ 4.5

Dividing both the side by 1.5 we get,

t ≤ 3

this is the total hours she can use the boat without spending more than $7.00

Thus, Malike can use the boat for 3 hours without spending more than $7.00

Answer:

2.29 inches/hour

Step-by-step explanation:

Given that the candle burns at a constant rate.

After time 2.7 hours, candle was 14.3 inches tall.

After time 7.1 hours, candle was 4.2 inches tall.

To find:

The constant rate at which the candle burn.

Solution:

Let the length be represented by [tex]l[/tex] and time be represented by [tex]t[/tex].

Let the constant rate be [tex]m[/tex].

and the initial length be [tex]L.[/tex]

The equation can be written as:

[tex]l =mt+L[/tex]

At [tex]t[/tex] = 2.7 hours , [tex]l[/tex] = 14.3 inches

[tex]14.3 =2.7m+L ..... (1)[/tex]

At [tex]t[/tex] = 7.1 hours , [tex]l[/tex] = 4.2 inches

[tex]4.2 =7.1m+L ..... (2)[/tex]

Equation (1) minus (2):

[tex]10.1=-4.4m\\\Rightarrow m = - 2.29\ inches/hour[/tex]

The candle burns at the rate of 2.29 inches/hour.
