45 inch board cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece . find the lengths of all three pieces

Answers

Answer 1

Answer:65

Step-by-step explanation:

Answer 2

Length of first, second and third piece are 5, 15 ,25 inch

Given that;

Length of board = 45 inch

Second cut is 3 times as long as the first piece

Third cut is 5 times as long as the first piece

Find:

Length of all three piece

Computation:

Assume;

Length of first piece = a

So,

Length of second piece = 3a

Length of third piece = 5a

So,

Length of first piece + Length of second piece + Length of third piece = Total length

a + 3a + 5a = 45

9a = 45

a = 5

So,

Length of first piece = a

Length of first piece = 5 inch

Length of second piece = 3a = 3(5)

Length of second piece = 15 inch

Length of third piece = 5a = 5(5)

Length of third piece = 25 inch

Given in the figure below, find the values of X and Z.

Answers

Answer:

x = 6 , z = 79

Step-by-step explanation:

(8x + 53) and (6x + 43) are adjacent angles and sum to 180° , that is

8x + 53 + 6x + 43 = 180 , that is

14x + 96 = 180 ( subtract 96 from both sides )

14x = 84 (divide both sides by 14 )

x = 6

Then

6x + 43 = 6(6) + 43 = 36 + 43 = 79

z and 79 are vertical angles and congruent , then

z = 79

Answer:

x = 6

z = 79

Step-by-step explanation:

We know that angles on a straight line add up to 180.

With this in mind:

(6x+43)° + (8x+53)° = 180hence 14x+96=18014x=84x=6

For z:

since x = 6(8x+53)° + z° = 180101 + z = 180z = 79

Another approach using the property where opposite angles are equal:

(6x+43) = z79 = z

Joel has a goal to practice his clarinet for 4 ½ hours per week. The list below shows the number of hours Joel has practiced so far this week.

Answers

Answer:

3/4 hours

Step-by-step explanation:

Joel has a goal to practice his clarinet for 4 1/2 per week. The list below shows the number of hours Joel has a practiced so far for the week. Monday 1 1/2 hours Wednesday 1 1/4 hours Thursday 1 hour. How many more hours does he need to practice this week to meet his goal?

Total practice hours per week = 4 1/2 hours = 9/2 hours

Hours of practice so far for the week:

Monday = 1 1/2 hours = 3/2 hours

Wednesday = 1 1/4 hours = 5/4 hours

Thursday = 1 hour

Total = Monday + Wednesday + Thursday

= 3/2 + 5/4 + 1

= (6+5+4)/4

= 15/4 hours

How many more hours does he need to practice this week to meet his goal

Hours needed to meet goal = Total practice hours per week - Hours of practice so far for the week

= 9/2 - 15/4

= (18-15)/4

= 3/4 hours

Hours needed to meet goal = 3/4 hours

9) Is 0 a solution to 3x + 8 = 5x + 8? Explain or show your reasoning .

Answers

Answer:

x=0, yes.

Step-by-step explanation:

3x+8=5x+8

5x-3x+8=8

2x+8=8

2x=8-8

2x=0

x=0/2

x=0

Answer: yes

Explanation: To decide whether 0 is a solution for

this equation, we can simply plug a 0 in for x.

If the statement holds true, then 0 is a solution.

Plugging in 0 for x, we have 3(0) + 8 = 5(0) + 8.

Now since anything times 0 is 0, we have 8 = 8.

Since 8 = 8 is a true statement, 0 is a solution.

Belinda went biking on Saturday and rode for 6\frac{4}{5} miles on Sunday she rode for \frac{2}{3} of the distance she rode on Sunday

Answers

Complete question :

Belinda went biking on Saturday and rode for 6 4/5 miles. On Sunday she rode for 2/3 of the distance she rode on Saturday. Write and solve an equation that will help you figure out how far Belinda rode on Sunday

Answer:

4.5333 miles

Step-by-step explanation:

Number of miles biked on Saturday = 6 4/5 miles

Miles on Sunday = 2/3 of miles biked on Saturday

To obtain the distance biked on Sunday :

Fraction of miles biked on Sunday * miles biked on Saturday

Miles biked on Sunday = 2/3 * 6 4/5

Miles biked on Sunday = 2/3 * 34/5

Miles biked on Sunday = (2 * 34) / (3 * 5) = 68/15 = 4.5333 miles

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

Answers

Question:

Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

Answer:

[tex]y=x +45[/tex]

[tex]y = 45 + x[/tex]

Step-by-step explanation:

From the complete question, we have:

Jordyn & Teri

[tex]Rolls = 1[/tex]

[tex]Extra = 45\ yd[/tex]

Morgan

[tex]Rolls = 3[/tex]

[tex]Extra= 10\ yd[/tex]

Required

Expression for Jordyn and Morgan

Let the total kite by Jordyn and Teri be represented with y

This is calculated as:

[tex]y = Rolls + Extra\ Yard[/tex]

This gives:

[tex]y = 1\ roll + 45yd[/tex]

1 roll is represented with x.

So:

[tex]y=1x +45[/tex]

[tex]y=x +45[/tex]

This can be rewritten as:

[tex]y = 45 + x[/tex]

A salesperson earns a base salary of $32,500 per year plus a commission of 8% on total sales. Her total sales for one year were $450,000. Find the salesperson's total pay for the year.

Answers

The salesperson's total pay for the year is $68500

How to determine the total pay?

The given parameters are:

Base pay = $32,500

Commission = 8%

Total Sales = $450,000

The total pay is calculated as:

Total = Base pay + Commission * Total Sales

This gives

Total = $32,500 + 8% * $450,000

Evaluate

Total = $68500

Hence, the salesperson's total pay for the year is $68500
