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

Nutka1998 [239]

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 a triangle with vertices A,B and C, if C =64° and the lengths AC= 40mm and BC= 70mm find the length AB using cosine rule

boyakko [2]

Answer:

63.6mm

Step-by-step explanation:

According to cosine rule;

AB² = BC²+AC²-2(BC)(AC)cos m<C

Substitute the given values

AB² = 70²+40²-2(70)(40)cos 64

AB² = 4900+1600-5600cos64

AB² = 6500-5600(0.4384)

AB² = 6500-2,454.87

AB² = 4,045.12

AB = √4,045.12

AB = 63.6mm

Hence the length of AB is 63.6mm

Write each as a decimal. Round to the thousandths place.<br> 9) 78.4%<br> 10) 29%<br> Help

fomenos

Answer:

$(a) 78.4\% = 0.784$

$(b) 29\% =0.290$

Step-by-step explanation:

Required

As a decimal to nearest thousandth

Solving (a): 78.4%

$78.4\%$

Express as fraction

$78.4\% = \frac{78.4}{100}$

Solve fraction

$78.4\% = 0.784$ ----- This is already in thousandth place

Solving (b): 29%

$29\%$

Express as fraction

$29\% =\frac{29}{100}$

Solve fraction

$29\% =0.29$

Approximate

$29\% =0.290$

Test worth 75 points ; test score of 96%

vfiekz [6]

Presuming the question is "How many points did he miss", you would find the solution by multiplying the amount of possible points by the test score as a fraction. 96% is the fraction $\frac{96}{100}$ . Therefore, you get the equation $75*\frac{96}{100}$ . This is equal to 72, so he missed 3 points, or 75-72 points.

He missed 3 points.
