Step-by-step explanation:

If a, b, and c are solutions to the
equation 3x3 – 25x2 - 50x = 0 and
a < b < c, evaluate 10c – 6a.

Answers

Answer:

[tex]\displaystyle 10c - 6a = 110[/tex]

Step-by-step explanation:

We are given the equation:

[tex]\displaystyle 3x^3 - 25x^2 -50x = 0[/tex]

Where a, b, and c are solutions to the equation and where a < b < c, we want to determine the value of 10c - 6a.

To find the solutions of the equation, we can factor:

[tex]\displaystyle \begin{aligned} 3x^3 - 25x^2 -50x & = 0 \\ \\ x(3x^2 - 25x -50) & = 0 \\ \\ x(3x+5)(x-10) & = 0 \end{aligned}[/tex]

From the Zero Product Property:

[tex]\displaystyle x = 0 \text{ or } 3x + 5 = 0 \text{ or } x - 10 = 0[/tex]

Solve for each case:

[tex]\displaystyle x = 0 \text{ or } x = -\frac{5}{3} \text{ or } x = 10[/tex]

We can see that -5/3 < 0 < 10. Thus, a = -5/3, b = 0, and c = 10.

Therefore:

[tex]\displaystyle \begin{aligned} 10c - 6a & = 10(10) - 6\left(-\frac{5}{3}\right) \\ \\ &= 100 + 10 \\ \\ & = 110 \end{aligned}[/tex]

Step-by-step explanation

22 divided by 2 is 11

it says four years ago so add 11 and 4 and that equals 15

she is 15 right now. then add 22 which is 37 and subtract 4 which your answer would be 33

22 divided by 2 is 11

What is an equation of the line that passes through the points (4,4) and
(8, 1)?

Answers

Answer:

y = -3/4x + 7

Step-by-step explanation:

ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so

1 - 4 = -3

8 - 4 4

so the m is -3/4

now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)

so 1 = -3/4(8) + b

1 = -6 + b

+ 6 + 6

b = 7

so the equation is y = -3/4x + 7. hope this helps

find the unknown angle​

Answers

Answer:

x = 35 degrees

y = 70 degrees

z = 75 degrees

Step-by-step explanation:

X will equal 35 degrees because that angle is vertical to the 35 degree angle, which means they are equal.

To find the measure of angle z, subtract the outside angle from 180:

180 - 105 = 75

To find the measure of angle y, add the two other known angles of the triangle and subtract that from 180:

35 + 75 = 110

180 - 110 = 70

Answer:

x = 35, y=75, z=70

Step-by-step explanation:

I dont know which angle you wanted exactly. However x is equal to 35 (I'm sorry, I forgot the name of the rule that makes that way, I assume it's in your notes if this is for a class). Z is equal to 75 because a straight line(the one on the bottom) is equal to 180 degrees. Since you have an angle on that line already (105), just subtract 180-105 to get 75.

Lastly, since we have x and z now, we can add them and subtract from 180(the degree in a triangle. So 35+75 = 110 and 180-110 = 70.

Step-by-step explanation:

From the figure attached,

AB and CD are two parallel lines and another transverse line is intersecting these line at two distinct points.

Since, m∠1 = 32°,

∠1 and ∠4 are supplementary angles [Linear pair of angles]

m∠1 + m∠4 = 180°

32° + m∠4 = 180°

m∠4 = 180° - 32°

m∠4 = 148°

therefore,

m∠1,3,5,7 = 32°

JEN PURCHASED THE ITEM SHOWN IN THE TABLE IN THE CITY IN THE SALES TAX RATE IS 7.15 IN ANOTHER CITY THE SALES TAX RATE IS 6.35 HOW MUCH MORE IS SHE SPENDING IF SHE PURCHASED THE ITEM==EN IN THE CITY WHERE SHE LIVES

Answers

Answer:

First, calculate the amount of sales tax by multiply the percent tax times the total cost:

0.07×600 =42

Next, add the amount of tax to the price of the computer:

600+42=642

$0.45792 more is she spending if she purchases the items in the city where she lives.

Given that, Jen purchased the items shown on the table. In the city she lives in, the sales tax rate is 7.15%. In another city, the sales tax rate is 6.35%.

We need to find out how much more is she spending if she purchases the items in the city where she lives.

What is the sales tax?

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

Now, the cost of the goods she purchased=11.99+35.50+6.75+3.00

=$57.24

The sales tax rate is 7.15%.

So, the sales tax=7.15% of 57.24

=$4.09266

The sales tax rate is 6.35%.

So, the sales tax=6.35% of 57.24

=$3.63474

Now, 4.09266-3.63474=$0.45792

Therefore, $0.45792 more is she spending if she purchases the items in the city where she lives.

choose the correct solution and graph for the inequality "-x/3<=6"

Answers

Answer:

Step-by-step explanation:

To solve this inequality, we have to find x (or make x the subject of the inequality:

since     ⁻ˣ/₃  ≤ 6       [multiply both sides by 3]

               - x ≤ 18      [multiply both sides by -1; this flips the inequality sign]

              x ≥ - 18    [this is the solution]

To graph the inequality, draw the line x = - 18 with a solid line, and then shade the region that is x > -18.

We use a solid line because the point x = -18 is included. However, hypothetically,  if the inequality was x > -18 only, a broken line would be used to show that the line x = -18 is not included.

Janet worked 3 hours more than David and 7 hours less than Kate. David earned $7.50 per hour, Janet earned $6 per hour, and Kate earned $9 per hour. If Kate earned $27 more than David and Janet combined, how much did each person earn?​

Answers

We want to write and solve a system of equations to see how much each person earns.

What each one earned is:

Janet = $78Kate =  $180David = $75

Let's define:

J = number of hours that Janet worked.D = number of hours that David worked.K = number of hours that Kate worked.

The information is:

"Janet worked 3 hours more than David and 7 hours less than Kate"

From this we can write:

J = D + 3

J = K - 7

We know that:

David earned $7.50 per hour.Janet earned $6 per hour.Kate earned $9 per hour.

Finally, we know that Kate earned $27 more than David an Janet combined, then we can write:

$9*K = $27 + ($7.50)*D + $6*J

Then we have a system of equations:

J = D + 3

J = K - 7

$9*K = $27 + ($7.50)*D + $6*J

We can rewrite the first and second equations to get:

D = J - 3

K = J + 7

Now we can replace these two in the other equation to get:

$9*(J + 7) = $27 + ($7.50)*(J - 3)+ $6*J

Now we can solve this for J:

$9*J + $63 = $27 + $7.50*J - $22.50 + $6*J

$9*J - $7.50*J - $6*J = $27 - $63 - $22.50

-$4.50*J = -$58.60

J = (-$58.60)/(-$4.50) = 13

This means that Janet worked for 13 hours.

And with:

K = J + 7 = 13 + 7 = 20

D = J - 3 = 13 - 3 = 10

We can see that Kate worked for 20 hours and David for 10 hours.

Then each one of them earned:

Janet = 13*$6 = $78

Kate = 20*$9 = $180

David = 10*$7.50 = $75

Billy has 1 gallon of paint he’s going to pour it into a paint tray that measures 10 inches wide 14 inches long and 4 cm deep which of the following scenarios would happen

Answers

Answer:

Lets see if the gallon fill the paint tray or not.

For that purpose we need to find out the volume of the paint tray and compare it with the volume of the gallon.

Given:

Length = 14 inches

Width = 10 inches

Depth = 4 cm = 1.57 inches

Volume = length x width x depth

Volume = 14 x 10 x 1.57

            = 220.47 inches cube

Volume of Gallon = 231 inches cube

Comparing the two volumes:

231 inches cube - 220.47 inches cube = 10.52 inches cube

Hence,

The paint will not fill the tray by 10.53 in3.
