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.

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.

Answer:

The answer to this question would be (to my best guess), 36 hours.

Step-by-step explanation:

First

 You have to find the ratio between 87.5% and 100%. This is because you want to find what 100% represents.

To do this, you have to divide 100 by 87.5, which would represent 100 divided by 87.5. This will equal 1.142857142857143 , which isnt an easy number to work with.

Lastly

 You have to multiply 1.142857142857143 by 31.5, because you reverse the previous operation, but the only difference is you swap out the percentages with the numbers they represent. This equals the final answer, which is 36, representing 36 hours.

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:

a) How tall would the sunflower be after 10 weeks?

35 inches tall

Step-by-step explanation:

At the beginning of spring, Jeremiah planted a small sunflower in his backyard. When it was first planted, the sunflower was 15 inches tall. The sunflower then began to grow at a rate of 2 inches per week.

If the rate:

1 week = 2 inches

10 weeks = x inches

x = 10 × 2/1

x = 20 inches

How tall would the sunflower be after 10 weeks?

The initial height = 15 Inches

The height after 10 weeks =

15 inches + 20 inches

= 35 inches

C. Because (-3)^2 is NOT equal to -9

Step-by-step explanation:

Answer:

Answer:

x = 12

Step-by-step explanation:

[tex]\sqrt{3x}[/tex] + 10 = x + 4

[tex]\sqrt{3x}[/tex] = x - 6

( [tex]\sqrt{3x}[/tex] )² = ( x - 6 )²

3x = x² - 12x + 36

x² - 15x + 36 = 0

(x - 3)(x - 12) = 0

[tex]x_{1}[/tex] = 3

[tex]x_{2}[/tex] = 12

Check the answer:

[tex]\sqrt{3*3}[/tex] + 10 ≠ 3 + 4

13 ≠ 7 ⇒ 3 is not the root of original equation (strange root)

[tex]\sqrt{3*12}[/tex] + 10 = 12 + 4

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:

m∠4 = 57°

m∠5 = 123°

m∠6 = 35°

Step-by-step explanation:

m∠4 ≅ ∠57°

Therefore m∠4 = 57°

Following this rule of thumb

m∠6 ≅ 35°

m∠6 = 35°

m∠5 = 180 - 57

m∠5 = 123

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
