The length of a rectangle is twice the width. The area is 72 yd^2. Find the length and the width.

Answer:

-3/2

Step-by-step explanation:

You are going a distance of 3/2 to the right, to get 3/2. You are going the same distance of 3/2 to the left, to get -3/2. Same distance traveled on a number line, just in different directions making it positive/negative.

Answer:

There are 15 mechanical pencils

Step-by-step explanation:

Recall that the probability of drawn a mechanical pencil from a larger group is given by the quotient of the number of mechanical pencils divided the total number of pencils in the sample.

so that means:

[tex]P=\frac{x}{25} \\[/tex]

being x the number of mechanical pencils and 25 the total of all pencils in the sample. Since they give as P as 3/5, we can solve for the number of mechanical pencils (x) using the equation:

[tex]P=\frac{x}{25} \\\\\frac{3}{5} =\frac{x}{25}\\x=\frac{3\,*\,25}{5} \\x=15[/tex]

So there are 15 mechanical pencils in the sample.

Replace x, y, and z in the plane's equation with their appropriate parametric equations, then solve for t, then evaluate x, y, and z at this t to find the point P.

[tex]x+y-z=-5[/tex]

[tex](1+t)+2t-(-3t)=-5[/tex]

[tex]6t+1=-5[/tex]

[tex]6t=-6[/tex]

[tex]t=-1[/tex]

[tex]\implies x=0,y=-2,z=-3[/tex]

So the point P is (0, -2, -3).

Here, we are required to find the point, P where the lines:

intersects the plane x + y - z = -5.

The point, P where the lines intersects the plane is given by;

he point, P where the lines intersects the plane is given by;P (0, -2, 3)

Therefore, to find this point, we have to substitute for x, y and z in the equation of the plane.

Therefore, we have;

To get the coordinates of the point P where the lines intersect the plane; we can then find x, y and z by substituting t into each of their equations.

Therefore;

Therefore, the point, P where the lines intersects the plane is given by;

Answer:

firs find the least common multiple (LCM) of the denominators

Step-by-step explanation:

2/5+7/10

Multiples of 5 = {5,10,15,20,25,30,35...}

Multiples of 10 = {10,20,30,40,50...}

Common multiples = {10,20,30,...}

Least Common Multiples = {10}

2/5+7/10

= 2(2) + 7(1)

= 11/LCM

But the LCM = 10

Answer:

115°

Step-by-step explanation:

Measure of the degree of the angle represented by section B on the chart = percentage in the pie chart ÷ 100 × 360. A full circle makes 360°.

Section B represents 32% of the pie chart, therefore, number of degrees for section B = [tex] \frac{32}{100}*360 = \frac{32*360}{100} [/tex]

[tex] = 115.2 [/tex]

Section B = 115° (to the nearest whole number)

[tex]\boxed{\bold{\huge{\boxed{x = 10}}}}[/tex]

Step-by-step explanation:

=> [tex]\sf \frac{3}{4} x + \frac{5}{6} = 5x - \frac{125}{3}[/tex]

Combining like terms

=> [tex]\sf \frac{3x}{4} - 5x = -\frac{125}{3} - \frac{5}{6}[/tex]

Taking LCM to make the denominator same

=> [tex]\sf \large{\frac{3x-20x}{4} = \frac{-250-5}{6} }[/tex]

=> [tex]\sf \frac{-17x }{4} = \frac{-255}{6}[/tex]

=> [tex]\sf \frac{17x }{4} = \frac{255}{6}[/tex]

Cross Multiplying

=> [tex]\sf 17x * 6 = 4 * 255[/tex]

=> [tex]\sf 102x = 1020[/tex]

Dividing both sides by 102

=> x = 10

Answer:

JL = 166 units

Step-by-step explanation:

Given that,

JL = 9x - 5, LR = 7x - 2, and JR = 35

Let us assume that, R is the midpoint of J and L. So,

JL = JR + RL

Putting all the values,

9x - 5 =35 + 7x - 2

Taking like terms together as follows :

9x-7x = 33 + 5

2x = 38

x = 19

Put the value of x inm, JL = 9x-5

JL = 9(19)-5

JL = 166

The value of JL is 166 units.

Answer:

[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]

Step-by-step explanation:

So we have the equation:

[tex]|-4x+1|>3[/tex]

First, note that since the sign is greater than, this is an or inequality (not an "and" inequality). This is the student's first mistake.

So, let's solve this inequality.

Case 1:

[tex]-4x+1>3[/tex]

Subtract 1 from both sides:

[tex]-4x>2[/tex]

Divide both sides by -4:

[tex]x<-\frac{1}{2}[/tex]

The student did not flip the sign when doing this step, hence the incorrect answer.

You correctly spotted the student's mistake. Nicely done!

Case 2:

[tex]-4x+1<-3[/tex]

This is what you're missing: for this second instance, we must flip the sign to less than right away. This is because we are essentially multiplying the 3 by a negative. So, we must flip the sign in order to be correct.

Now solve. Subtract 1 from both sides:

[tex]-4x<-4[/tex]

Divide both sides by -4. Since we're dividing by a negative, flip the sign:

[tex]x>1[/tex]

So, our solutions are:

[tex]x<-\frac{1}{2}, x>1[/tex]

As mentioned previously, this is an or inequality. Therefore, our final answer is:

[tex]x<-\frac{1}{2}\text{ or } x>1[/tex]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-2,-2) and slope 42

The equation of the line is

[tex]y + 2 = 42(x + 2) \\ y + 2 = 42x + 84 \\ y = 42x + 84 - 2[/tex]

We have the final answer as

[tex]y = 42x + 82[/tex]

[tex]x = 1.28[/tex]

Step-by-step explanation:

Given

Required

Solve for x

[tex]95 = 35^x[/tex]

Take Log of both sides

[tex]Log95 = Log35^x[/tex]

Apply law of logarithm

[tex]Log95 = xLog35[/tex]

Divide both sides by Log35

[tex]x = \frac{Log95}{Log35}[/tex]

[tex]x = \frac{1.97772360529}{1.54406804435}[/tex]
