Dogs lap water to drink it. Every 3 minutes a dog laps water, it gets 30 ounces. If a dog needs 155 ounces per day, predict how many minutes the dog will lap water.

Answers

Answer:

15 minutes and 51 seconds

Step-by-step explanation:

155/30 = 5.17

5.17 x 3 = 15.51

It will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

Here, we have to predict how many minutes a dog will lap water to consume 155 ounces per day, we can set up a proportion based on the given information:

1 dog laps water every 3 minutes and gets 30 ounces.

Therefore, in 1 minute, a dog laps 30/3 = 10 ounces.

Now, we want to find out how many minutes it takes for the dog to consume 155 ounces:

Let x be the number of minutes the dog laps water to consume 155 ounces.

Proportion:

(Ounces lapped in x minutes) / (Ounces lapped in 1 minute) = (Total ounces needed) / (Ounces lapped in 1 minute)

(10x) / 10 = 155 / 1

Simplify the equation:

10x = 155

Now, solve for x:

x = 155 / 10

x = 15.5

So, it will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

A local phone company offers a cell phone plan that has a fixed cost per month and a cost related to the number of text messages sent. The fixed cost is $20 and each message sent costs 10€. Represent the relation between the total cost and the number of text messages sent, as many different ways as you can.

Answers

Answer:

20 + 10(x) = total cost

Step-by-step explanation:

x represents the number of messages, so you multiply it by 10. 20 is a fixed number so you just add it without changing its value.

Subtract 8n from both sides:

N = 8

->Solution

i) 9n = 8n+8 [ V.O.A. vertically opposite angles ]

or, 9n - 8n = 8

or, n = 8

therefore, value of n is 8

The 25th term of an arithmetic series is 44.5

The sum of the first 30 terms of this arithmetic series is 765

Find the 16th term of the arithmetic series.

Show your working clearly.

Answers

Answer:

[tex]a_{16}=26.5[/tex]

Step-by-step explanation:

Arithmetic series: [tex]a_n=a+(n-1)d[/tex]

Sum of arithmetic series: [tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]

(where a is the first term and d is the common difference)

Given:

[tex]a_{25}=44.5[/tex][tex]S_{30}=765[/tex]

[tex]\implies a_{25}=44.5[/tex]

[tex]\implies a+(25-1)d=44.5[/tex]

[tex]\implies a+24d=44.5[/tex]

[tex]\implies S_{30}=765[/tex]

[tex]\implies \dfrac{30}{2}[2a+(30-1)d]=765[/tex]

[tex]\implies 30a+435d=765[/tex]

Rewrite [tex]a+24d=44.5[/tex] to make a the subject:

[tex]\implies a=44.5-24d[/tex]

Substitute found expression for a into [tex]30a+435d=765[/tex] and solve for d:

[tex]\implies 30(44.5-24d)+435d=765[/tex]

[tex]\implies 1335-285d=765[/tex]

[tex]\implies 285d=570[/tex]

[tex]\implies d=2[/tex]

Substitute found value of d into [tex]a=44.5-24d[/tex] and solve for a:

[tex]\implies a=44.5-24(2)=-3.5[/tex]

Therefore:

Answer:

The correct answer is C: [tex]t\leq 58[/tex]

Step-by-step explanation:

In order to solve this problem, start by first creating an inequality to represent the situation above. The price of the hours and the supply fee can't go over $1,500, so you can set the representative inequality as [tex]25t+50\leq 1500[/tex]. Now solve the inequality, and you will get [tex]25t+50\leq 1500[/tex] => [tex]25t\leq 1450[/tex] => [tex]t\leq 58[/tex] hrs. So C is the correct answer.

Answer:

The answer is C.t is less than or equal to 58.

Step-by-step explanation:

Let x = Number of tutoring sessions

Supplies + tutoring cost = total cost

50 + 25x = 1500

Now need to solve:

Subtract 50 from both sides and simplify

50/ + 25x - 50 = 1500 - 50

25x = 1450

Divide both sides by 25 and simplify

25x/25 = 1450/25

Therefore,

[tex]x\leq 58[/tex]

Answers

Answer:

Part A is ≤ means less than OR equal to. < only means less than

Part B is 9

Step-by-step explanation:

A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.

In circle L, AD is 10 units long. Which of the following lengths are even numbers? Select all that apply.

(SEE ATTACHED PHOTO)

Answers

The chords in the circle L are illustrations of intersecting chords

The lengths that are even numbers are FJ and GJ

How to determine the even lengths?

The length AD is given as:

AD = 10

From the circle, we have:

AD = AH + HK + KD

Where:

AH = 3 and KD = 2

So, we have:

10 = 3 + HK + 2

Solve for HK

HK = 5 ---- odd length

Next, we calculate length FH using the following intersecting chord theorem

FH * HB = AH * HD

This gives

(FJ + 3) * 3 = 3 * (2 + 5)

Divide by 3

FJ + 3 = 7

Subtract both sides by 3

FJ = 4 --- even length

Next, we calculate length KE using the following intersecting chord theorem

KE * KC = KD * KA

This gives

KE * 3.2 = 2 * (5 + 3)

Evaluate the product

KE * 3.2 = 16

Divide by 3.2

KE = 5 --- odd length

Next, we calculate length GJ using the following intersecting chord theorem

GJ * JE = FJ * JB

This gives

GJ * 4.5 = 4 * (6 + 3)

Evaluate the product

GJ * 4.5 = 36

Divide by 4.5

GJ = 8 --- even length

Hence, the lengths that are even numbers are FJ and GJ

Multiplying a number by 3 is equal to sum of the number and 5.

Answers

Answer:

this makes no sense

Step-by-step explanation:

The number that when multiplied by 3, equals the sum of the number and 5 is 2.5.

How can we solve for 2.5?

First assume that the number we are looking for is x.

One side of the equation will be:

= 3 × x

= 3x

The other side of the equation would be:

= 5 + x

Equating these numbers gives:

3x = 5+ x

3x - x = 5

2x = 5

x = 5/ 2

x = 2.5

In conclusion, the number is 2.5.

Which rule dilates a figure in the coordinate plane by a scale factor of 5?

Answers

Dilation involves changing the size of a figure

The dilation rule of a figure in the coordinate plane by a scale factor of 5 is (b) (x,y) [tex]\to[/tex] (5x,5y)

How to determine the dilation rule?

The scale factor (k) is given as:

k = 5

Assume the coordinates of the figure is (x,y)

The dilation rule would be:

(x,y) [tex]\to[/tex] k(x,y)

Substitute 5 for k

(x,y) [tex]\to[/tex] 5(x,y)
