Hector has $590 in his account. He earned $15 per hour for x hours. Jeremy has $545 in his account. He earned $20 per hour for x hours. They both worked the same number of hours and now have the same amount of money. What is the number of hours that each person worked? Write and solve an equation.

Answers

Answer 1

Answer:

equation = 590 + 15x = 545 + 20x

No. of hours worked = 9

Step-by-step explanation:

Given that both worked for same number of hours

and

Jeremy worked for for x hours

it meant that Hector also worked for x hours(it is also mentioned same in the problem)

now that we know the number of hours worked in form of x

lets find

total money in their account if they worked for x hours

___________________________________________

For Hector

Money in Hector's account = $590

Earning for Hector in 1 hour = $15

Earning for Hector in x hour = x*Earning for Hector in 1 hour = $15x

Total money in with Hector after x hours of work

 = Money in Hector's account + Earning for Hector in x hour = $590 + $15x

Similarly

For Jeremy

Money in Jeremys account = $545

Earning for Jeremy in 1 hour = $20

Earning for Jeremy in x hour = x*Earning for Jeremy in 1 hour = $20x

Total money in with Jeremy after x hours of work

 = Money in Jeremy's account + Earning for Jeremy in x hour = $545 + $20x

Given that they same amount of money

thus

$590 + $15x = $545 + $20x

$sign gets cancelled from both sides

590 + 15x = 545 + 20x  Thus, we got the required equation  

=> 590 - 545 = 20x - 15x

=> 45 = 5x

=> x = 45/5 = 9

Thus, both of them worked for 9 hours

In isosceles triangle DAC, AD is congruent to AC. Kiran knows that the base angles of an isosceles triangle are congruent. What additional
information does Kiran need to know in order to show that AB is a perpendicular bisector of segment CD?

Answers

A perpendicular bisector is a line that crosses (bisects) another line segment at 90 degrees, dividing the line segment it crosses into two equal length lines

The additional information Kiran need to know to show that AB is a perpendicular bisector is the fourth option;

DB and BC are congruent

The reason for the above selection is as follows:

The information about the isosceles triangle DAC Kiran knows are;

Triangle DAC = An isosceles triangle

Segment AD is congruent to segment AC

Segment AB is a  is a line from the vertex point A to the side CD of triangle DAC

The required parameter:

The information Kiran has know so as to show that AB is a perpendicular bisector of CD

Method:

Determine an attribute present in triangle DAC with line AB drawn that is due to line AB being a perpendicular bisector

Solution:

For AB to be a perpendicular bisector, then DB and BC are congruent

Given that DB and BC are congruent, we get;

AB is congruent to AB by reflexive property

Therefore, given that AD is congruent to AC, we have;

Sides AD, AB, and DB in triangle ΔADB are congruent to the corresponding sides AC, BC, and AB in triangle ΔACB, which gives

ΔADB is congruent to ΔACB by Side-Side-Side, SSS, congruency rule

Therefore, ∠ABD ≅ ∠ABC, by Congruent Parts of Congruent Triangles are Congruent, CPCTC

∠ABD = ∠ABC by definition of congruency

∠ABD and ∠ABC are linear pair angles, therefore;

∠ABD + ∠ABC = 180°

∠ABD + ∠ABD = 2 × ∠ABD = 180° by substitution property

∠ABD = 180°/2 = 90°

∠ABD = 90° = ∠ABC, therefore, AB is perpendicular to CD and AB is a perpendicular bisector of CD

Therefore, the correct option Kiran need to know in order to show that AB is a perpendicular bisector of segment CD is the option; DB and BC are congruent

Angela lives 0.6 mile from the park. It takes her hour to walk her dog to the park. How quickly are Angela and her dog walking in miles per hour?​

Answers

Answer:

0.6 miles an hour

Step-by-step explanation:

since it takes her 0.6 miles to walk an hour and an hour to walk 0.6 miles.

0.6 = 3/5

Answer: 0.1 miles per hour

Since an hour has 6 10-minute segments, divide by 6.

0.6 ÷ 6 = 0.1

Your answer should be 0.1 miles per hour.

So, Angela and her dog are walking at 0.1 miles per hour.

Find the error and explain what the correct step should be

Answers

Answer:

m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer

Step-by-step explanation:

okay, so you want to get m

because m is divided by 3, to counter it, you multiply both sides by three

-m/3 = -4

-m/3 times 3 =-4 times 3

because 1/3 times 3 =1, and -4 times 3 = -12, you get

-m = -12

then, divide both sides by - (because you want positive m)

and you get m = 12

the error was that the student did not divide by the negative, so in the end, their sign was wrong.

A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?

Answers

Answer:

[tex]\huge\boxed{\texttt{480 miles}}[/tex]

Step-by-step explanation:

We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.

We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form  [tex]\frac{miles}{hours}[/tex] .

[tex]\frac{720}{6}[/tex]

We can now make another ratio where we use a variable for the miles flown in 4 hours.

[tex]\frac{x}{4}[/tex]

Since the ratios are equal, we can create an equation.

[tex]\frac{720}{6}=\frac{x}{4}[/tex]

To find the value of x, let's cross multiply.

[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]

So the plane flew 480 miles in 4 hours.
