Answer:

6

Step-by-step explanation:

2y/3 + 1/3 = y/2 + 1/6

We want to eliminate the fractions

The least common multiple of 3,2 and 6 is 6

Multiply each side by 6 to get rid of the fractions

6(2y/3 + 1/3) = 6(y/2 + 1/6)

4y +2 = 3y +1

Answer:   [tex]\bold{a)\ \overline{CD}=6\qquad b)\ \overline{AD}=\dfrac{32}{3}\qquad c)\ \overline{AC}=\dfrac{50}{3}\qquad d)\ \overline{OB}=\dfrac{25}{3}}[/tex]

Step-by-step explanation:

a) First, use the Pythagorean Theorem to find CD:

8² + (CD)² = 10²     →     CD = 6

d) Next, find OB.  Notice that both OB and OC are the radius of the circle.

Using the Segment Addition postulate, we know the radius (r) = CD + DO  →  DO = r - 6

Use the Pythagorean Theorem for ΔOBD to find OB:

(DO)² + (BD)² = (OB)²

(r - 6)² + 8² = r²

r² - 12r + 36 + 64 = r²

   -12r + 100        = 0

             100        = 12r

              [tex]\dfrac{25}{3}\quad = r[/tex]              

c) Now, find AC. Notice that AC is the diameter.

Diameter = 2r

               = 2(OB)

               [tex]=2\bigg(\dfrac{25}{3}\bigg)\qquad =\dfrac{50}{3}[/tex]  

b) Lastly, find AD. Using the Segment Addition Postulate, we know that

AD + CD = AC   →   AD = AC - CD

                                      [tex]= \dfrac{50}{3}-6\qquad \rightarrow \quad \dfrac{50}{3}-\dfrac{18}{3}\qquad =\dfrac{32}{3}[/tex]

The next three terms of the arithmetic sequence 5, 9, 13, 17 is 21, 25, 29.

Given that,

Based on the above information, we can see that

There is the addition of 4 in each next number i.e.

5 + 4  = 9

9 + 4 = 13

13 + 4 = 17

17 + 4 = 21

21 + 4 = 25

25 + 4 = 29

Therefore, the option d is correct

Hence, the other options are incorrect.

Therefore we can conclude that the next three terms of the arithmetic sequence 5, 9, 13, 17 is 21, 25, 29.

Answer:

Step-by-step explanation:

Answer:

x = -2[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

First we have to distinguish the numbers with x from the "normal" numbers.

2x and 6x are numbers with x.

3 and 0 are "normal" numbers.

Now we have to seperate them on different sides of the equal sign.

To do this, we can subtract 3 from the left side and then add it to 0 on the left side.

Therefore, the equation will now be 2x + 6x = -3.

Now we can add 2x and 6x together, making it 8x.

The equation will now be 8x = -3.

To find the product of x, we need to divide both sides together.

So 8 divided by -3 will make -2[tex]\frac{2}{3}[/tex].

Therefore, x is  -2[tex]\frac{2}{3}[/tex].

Answer: $2009.66

Step-by-step explanation:

A = P(1 + r/n)^nt

The balance at the end of 10 years in account after the credit union drawing 7% compounded monthly is $2009.66

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{n\times100}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

A thousand dollars is left in a credit union drawing 7% compounded monthly. The balance at the end of 10 years has to be find out.

Here the data given are,

Put these values in the above formula as,

[tex]A=1000\times\left(1+\dfrac{7}{12\times100}\right)^{12\times10}\\A=2009.66[/tex]

Thus, the balance at the end of 10 years in account after the credit union drawing 7% compounded monthly is $2009.66

Answer:

y=3x+5

Step-by-step explanation:

y=y=y=x+x+x+5 is what I think you were saying. In that case:

y=x+x+x+5

y=3x+5

The equation of the line is y=3x+5

The equation of the given line is y = 2/3 x - 2

The standard form of the equation of a line is expressed as y = mx + b

m is the slope of the line

b is the y-intercept

from the diagram attached, we can use the coordinate (0, -2) and (3, 0)

Get the slope

Slope "m" = 0-(-2)/3-0

m = 2/3

Since the line cuts the y-axis at y = -2, hence the y-intercept is b = -2

Substitute the given parameters into the equation:

y = mx + b

y = 2/3 x + (-2)

y = 2/3 x - 2

Hence the equation of the given line is y = 2/3 x - 2

Answer:

179

Step-by-step explanation:

The total number of animals in the river was 632.

A herd of 187 elephants and 266 zebras left the river area.

Adding them up, the total number of animals that left the river area is:

187 + 266 = 453

Therefore, the total number of animals left at the river area is the subtraction for the animals that left the river area from the number of animals that were there initially:

632 - 453 = 179

Answer:

2x^2+4x-30=0

Step-by-step explanation:

2x^2+10x-6x-30=0

2x(x+5)-6(x+5)=0

(2x-6)(x+5)=0

2x-6=0        x+5=0

x=6/2          x=-5

x=3

Answer:

Step-by-step explanation:

[tex]2x^2+4x-30=0\\<=> x^2+2x-15=0[/tex]

so we know that the sum of the two solutions is -2 and the multiplication -15

so we are looking for x so that

x+3=-2 and 3x=-15

it gives x = -5

another way to do it is to put (x-3) in factor as we know that 3 is one of the solutions it gives

[tex]2x^2+4x-30 = 2(x-3)(x+5)[/tex]

and then the second solution is -5

Answer:

67.5 degrees

Step-by-step explanation:

The piece that isn't marked with xs is 90 degrees marked by the square symbol representing a right angle.

Full circle = 360 degrees

360 degrees - 90 degrees = 270 degrees

Now, if we add all the like terms we have 4 x's in total. This is becauswe 3x + another x = 4x.

So, we need to divide 270 by 4. We get 67.5 degrees.

Answer:

289 units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Here C = 907.46 , thus

907.46 = πd ( divide both sides by π )

d = [tex]\frac{907.46}{\pi }[/tex] ≈ 289 units ( nearest whole number )

Answer:

[tex]d = 288.84 \: \: \: units[/tex]

Step-by-step explanation:

Using the formula

[tex]c = 2\pi \: r[/tex]

Solving for r

[tex]r = \frac{c}{2\pi} = \frac{907.46}{2\pi} \\ = 144.42674 \\ [/tex]
