Look at the example problem. Suppose Alana walks 6.6 miles the next day. Complete the steps below to find the number of miles she walks in two days.

|12x + 1| = 10

Remove the absolute value term and make two equations:

12x +1 = 10

12x +1 = -10

Now solve for both x values:

12x +1 = 10

Subtract 1 from both sides:

12x = 9

Divide both sides by 12:

x = 9/12

12x +1 = -10

Subtract 1 from both sides:

12x = -11

Divide both sides by 12:

x = -11/12

The answer would be (-11/12, 912)

Answer:

The amount invested at 4% was $3,000 and the amount invested at 7% was $8,000

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=1\ year\\ P_1=x\\P_2=11,000-x\\I=\$680\\r_1=4\%=4/100=0.04\\r_2=7\%=7/100=0.07[/tex]

substitute in the formula above

[tex]I=P_1(r_1t)+P_2(r_2t)[/tex]

[tex]680=0.04x+(11,000-x)0.07[/tex]      

solve for x

[tex]680=0.04x+770-0.07x[/tex]

[tex]0.07x-0.04x=770-680[/tex]

[tex]0.03x=90[/tex]

[tex]x=\$3,000[/tex]

so

[tex]\$11,000-x=\$11,000-\$3,000=\$8,000[/tex]

therefore

The amount invested at 4% was $3,000 and the amount invested at 7% was $8,000

Step-by-step explanation:

To construct a parallel line, set the compass to the same opening used for the first arc and draw an arc from point G that intersects line GD. This creates a parallel line to line EF through G.

To construct a line parallel to EF through point G, Francis should set the compass point on G and adjust the compass to the same opening that was used to construct the first arc. He then needs to create an arc that intersects GD on the opposite side of point A and extends to the right of point G. This step ensures that the line through G will have the same angle with GD as EF does with GD, allowing it to be parallel to EF.

Alejandro read 4 pages in 6 minutes, then it would take him 9 minutes to read 6 pages

Solution:

Given that Alejandro read 4 pages in a book in 6 minutes

Therefore,

4 pages = 6 minutes

Let us find the time taken to read 1 page

time taken to read 1 page = time taken to read 4 pages divided by 4

[tex]\text{ time taken to read 1 page } = \frac{6 minutes}{4} = \frac{3}{2} minutes[/tex]

Thus to read 6 pages at this rate, multiply time taken to read 1 page by 6

[tex]\rightarrow \frac{3}{2} \times 6 = 9[/tex]

Therefore it would take 9 minutes to read 6 pages

The diameter of circle is 1.018 mm.

Step-by-step explanation:

Given,

Circumference of circle = 3.2 mm

We know that;

Circumference = 2πr

[tex]3.2=2\pi r\\[/tex]

Putting π=22/7

[tex]3.2=2*\frac{22}{7}*r\\3.2=\frac{44}{7}r[/tex]

Multiplying both sides by 7/44

[tex]\frac{7}{44}*3.2=\frac{7}{44}*\frac{44}{7}r\\\\\frac{22.4}{44}=r\\\\r=0.509[/tex]

Diameter = 2r

Diameter = 2*0.509

Diameter = 1.018 mm

The diameter of circle is 1.018 mm.

Answer:

150

Step-by-step explanation:

60 minutes in 1 hour

3x10= 30 in one hour

30x5=150 30 trucks in 5 hours

Tarzan can load 150 trucks in 5 hours.

To calculate how many trucks Tarzan can load in 5 hours based on the rate that he loaded 3 trucks in 6 minutes. First, we convert 5 hours into minutes to match the units of the given rate. There are 60 minutes in 1 hour, so 5 hours is 300 minutes (5 hours x 60 minutes/hour). Next, we need to find out how many 6-minute intervals there are in 300 minutes, which is 300 minutes / 6 minutes/intervals = 50 intervals. Since Tarzan loads 3 trucks per interval, we multiply the number of intervals by the number of trucks per interval to get the total number of trucks loaded in 5 hours: 50 intervals x 3 trucks/interval = 150 trucks.

[tex]L=\frac{15}{16}\ yd[/tex]

Step-by-step explanation:

The correct question is

Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?

we know that

The area of a rectangle is equal to

[tex]A=LW[/tex]

where

L is the length

W is the width

we have

[tex]A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd[/tex]

substitute

[tex]\frac{5}{16}=L(\frac{1}{3})[/tex]

solve for L

[tex]L=\frac{5}{16}(3)[/tex]

[tex]L=\frac{15}{16}\ yd[/tex]

The length of the wood board must be approximately 39.69 yards.

To find the length of the board, we need to divide the total area by the width of the board. The area of the board is 516 square yards and the width is 13 yards.

Therefore, the length of the board can be found by dividing 516 by 13.

516 ÷ 13 = 39.69 yards.

So, the board must be approximately 39.69 yards long to complete the project.

Step-by-step explanation:

1) To Rewrite it as Slope-intercept form, is to isolate the y on the left side and on the right side the rest of the inequality.

[tex]-x+3y>6\Rightarrow 3y>x+6 \Rightarrow y> \frac{x+6}{3}\Rightarrow y> \frac{x}{3}+2[/tex]

2) Since this is a linear inequality the y intercept is given by "b" parameter.[tex]y> mx+b \Rightarrow y> \frac{x}{3}+2 \Rightarrow b=2[/tex]

So the y-intercept is y > 2, coordinate point (0,2). In the graph, we have a dashed line over 2.

3) Since there no choices, the points that satisfy this inequality lie within the green area. We know that the points for this inequality must satisfy  x < -6 or y> 2:

The amount of wax needed to create one set of candles is 84.75 cubic inches.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

Let's calculate the volume of each candle and then add them together to find the total wax needed for one set of candles.

For the smallest candle, the radius is 0.5 inches and the height is 3 inches, so the volume is:

V1 = π x (0.5)² x (3) = 0.75π cubic inches

For the medium-sized candle, the radius is twice as big, or 1 inch, and the height is twice as big, or 6 inches. So the volume is:

V2 = π x (1)² x (6) = 6π cubic inches

For the largest candle, the radius is three times as big, or 1.5 inches, and the height is three times as big, or 9 inches.

V3 = π x (1.5)² x (9) = 20.25π cubic inches

To find the total wax needed for one set of candles, we add up the volumes:

V (total) = V1 + V2 + V3

= 0.75π + 6π + 20.25π

= 27π cubic inches

= 27 x 3.14

= 84.78 cubic inches

Therefore,

The amount of wax needed to create one set of candles is 84.75 cubic inches.

(C) 36

Step-by-step explanation:

The length of the continuous solid path from P To Q = 3×(Length of the dashed line) = 3×(12) = 36 in.

:)

=========================================

Explanation:

Check out the attached image below. Basically I drew out the given diagram and then I added the variables a,b,c,d,e,f,g. Those variables represent the side lengths of the 7 squares. Each square has a perimeter of 4*s where s is the side length, but we dont consider the side that is running along the dashed line (that connects P directly to Q). So we have 3 sides per square added up.

The first square has us travel a distance of 3*a, then the second square a distance of 3*b and so on. Overall, the total distance traveled is

3a+3b+3c+3d+3e+3f+3g = 3(a+b+c+d+e+f+g)

The goal is to figure out what a+b+c+d+e+f+g is equal to. This is equal to the length of segment PQ since the 7 letters are pieces of segment PQ (i.e., I'm using the segment addition postulate).

In other words,

a+b+c+d+e+f+g = 12

3(a+b+c+d+e+f+g) = 3*12

3(a+b+c+d+e+f+g) = 36

Total distance traveled = 36

How many objects are required to keep the computer busy for exactly 9 seconds?

Round to the nearest whole object.

Answer:

42 objects are required to keep the computer busy for exactly 9 seconds

Solution:

Given function is:

Computer can sort x objects in t seconds, as modeled by the function below:

[tex]t = 0.005x^2+0.002x[/tex]

We have to find number of objects required to keep the computer busy for exactly 9 seconds

Therefore t = 9

Substitute t = 9 in given function

[tex]9 = 0.005x^2+0.002x\\\\0.005x^2+0.002x - 9 = 0[/tex]

Let us solve the above equation by quadratic formula,

[tex]\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0\\\\x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

Using the above formula,

[tex]\text{ for } 0.005x^2+0.002x - 9 = 0 , \text{ we have } a = 0.005 ; b = 0.002 ; c = -9[/tex]

Substituting the values of a = 0.005 ; b = 0.002 ; c = -9 in above quadratic formula we get,

[tex]\begin{aligned}&x=\frac{-0.002 \pm \sqrt{0.180004}}{0.01}\\\\&x=\frac{-0.002 \pm 0.4242}{0.01}\\\\&x=\frac{-0.002+0.4242}{0.01} \text { or } x=\frac{-0.002-0.4242}{0.01}\\\\&x=42.22 \text { or } x=-42.62\end{aligned}[/tex]
