Answer: n=4

Step-by-step explanation:

1) add 3 to both sides: 5n=20

2) divide by five on both sides: 5n/5 and 20/5

3) answer n=4

Answer:

17+3=20

20/5 = 4

5(n)-3 + 17

5(4) - 3 = 17

20-3 = 17

n = 4

[tex]y= a(x-p)(x-q)[/tex]

Answer:

       The x-intercepts

[tex]y[/tex] can only be [tex]0[/tex], if either [tex]x=p[/tex], or [tex]x=q[/tex]...

so, the parabola must have the points [tex]\left(p,0\right)[/tex] and [tex]\left(q,0\right)[/tex]

Step-by-step explanation:

First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.

Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.

Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.

Answer:

The required distance is 17.34 meters.

Step-by-step explanation:

The lengths of the two wires are 12 meters and 16 meters. and the angle between the wires is 75°.

Now, we have to calculate the distance between the wires on the ground.

Therefore, we have to calculate the length of the side which is the opposite side of angle 75° of the triangle formed by the wires and the ground.

Applying the formula of properties of the triangle, if the length required is x, then

[tex]\cos 75^{\circ} = \frac{12^{2} + 16^{2} - x^{2}}{2 \times 12 \times 16}[/tex]

⇒ 99.38 = 144 + 256 - x²

⇒ x = 17.34 meters. (Answer)

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothegm. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothegm = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Step-by-step explanation:

Assume n is the number of times she pick a skittle out of the bag

The probability she pick out red : 8/n

The probability she pick out yellow : 12/n

=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.

But we have 50 skittles, so the likely numbers of reds in the bag is = 2*[tex]\frac{50}{5}[/tex] = 20

Final answer:

To multiply 52.48 by 10⁵, move the decimal point five places to the right, resulting in a final product of 5248000.

Explanation:

To determine the product of 52.48×10⁵, you should move the decimal point in 52.48 a certain number of places to the right. Since we are multiplying by 105, which is the same as 10 to the power of five, we have five zeros after the 1 in 10 to the power of 5. Therefore, we move the decimal point five places to the right. Sometimes we may not have enough digits, and in such a case, we add zeros as placeholders.

Performing this movement with our number 52.48 gives us:

52.48 (original number)

524.8 (after moving 1 place)

5248 (after moving 2 places)

52480 (after moving 3 places)

524800 (after moving 4 places)

5248000 (after moving 5 places)

Therefore, the product of 52.48 and 10 to the power of 5 is 5248000.

Answer:

well bart has 20.00

andy took      19.65

Step-by-step explanation:

subtract [tex]20.00\\-19.65\\\\_______\\0.35[/tex]

your answer should be 0.35

Bart had $20, and Andy took $19.65. Bart will have $0.35 remaining.

Start with Bart's initial amount: $20

Subtract the amount Andy took:

$20 - $19.65 = $0.35

Therefore, Bart will have $0.35 remaining.

Answer:

No.

The most appropriate unit to measure the mesoplankton is centimeter.

The size is 2 cm.

Step-by-step explanation:

Earlier, you found the size of a mesoplankton to be [tex]2 \times 10^{-2}[/tex] meter.

I think that meters are not the most appropriate unit to represent the size of a mesoplankton.

The most appropriate unit to measure the mesoplankton is centimeter.

Now, 1 meter is equivalent to 100 centimeters.

So, the size of the mesoplankton in centimeter units will be [tex]2 \times 10^{-2} \times 100 = 2[/tex] cm. (Answer)

Final answer:

Meters are not the most appropriate unit for the size of a mesoplankton; millimeters are more suitable considering the small size of these organisms. The size 2 x 10² meters seems to be a typo and should likely be a much smaller value, such as 2 millimeters.

Explanation:

No, meters are not the most appropriate unit to represent the size of a mesoplankton. Considering that a mesoplankton is quite small, much smaller than objects like a piece of paper or a human's wingspan, using meters would not provide a practical or convenient measurement scale.

Since mesoplankton are small, it is important to think about units that are suitable for measuring very small objects. Given the metric units millimeters and centimeters are the next best alternatives. In this case, centimeters, being smaller than meters are a better match for the size of mesoplankton, but even centimeters might be too large.

Therefore, the most appropriate unit of measurement for the size of a mesoplankton is likely to be in millimeters. Therefore, 2 x 10^2 meters (200 meters) appears to be a typo, as mesoplankton would typically measure less than 2 centimeters. Assuming the intended measurement was supposed to be much smaller, converting to millimeters would be the best approach. An actual mesoplankton might measure around 2 millimeters, though this is just an example since the original measurement given seems incorrect.

Answer: 9h x 8n^2

we rearrange this underneath the question (-5h-2h) (2nx3n)(2+2) or if 2^2 see explanation. It must therefore be 7h6n4

Step-by-step explanation:

if its ^2 )(power2) then the second reasonable answer is (7h-2h)(2n^2 x 2n^2)=9h x 4n^2 x4n^2 =9h 8n^2 or 17hn^2 but i leave as 9h 8n^2

You can expand only if multiplying 9hx4 for example but not combine the letters. The questions that ask you to mix are much different to this. but if you want to add them 9h+8n^2 =17hn^2

Option D: [tex](3,14)[/tex] is the point of intersection of the two lines.

Explanation:

The two equations are [tex]y-6 x=-4[/tex] and [tex]y-2 x=8[/tex]

We need to find the point of intersection of the two lines.

Thus, let us solve the equation by substitution method.

From the equation [tex]y-6 x=-4[/tex], we shall determine the value of y, by adding both sides of the equation by 6x.

Hence, we have, [tex]y=6x-4[/tex]

Now, substituting [tex]y=6x-4[/tex] in the equation [tex]y-2 x=8[/tex] , we get,

[tex]6x-4-2 x=8[/tex]

       [tex]4x-4=8[/tex]

             [tex]4x=12[/tex]

               [tex]x=3[/tex]

Substituting [tex]x=3[/tex] in the equation [tex]y-6 x=-4[/tex], we get,

[tex]y-2 (3)=8[/tex]

   [tex]y-6=8[/tex]

         [tex]y=14[/tex]

Thus, the point of intersection of the two lines is [tex](3,14)[/tex]

Therefore, Option D is the correct answer.

Equation is a(n) = 12 + 8n

Step-by-step explanation:

a(n) = a + (n -1)d

a(n) = 20 + (n - 1)8

      = 20 + 8n - 8

      = 12 + 8n

∴ Equation is a(n) = 12 + 8n

Answer:

12+8n

Step-by-step explanation:

This is sequence and series

Using the formula,a+(n-1)d

a means the first number

n means the number of progression

d means the difference

a=20

n=?

d=8

Apply the formula

=20+(n-1)8

=20+(8n-8)

=20+8n-8

=20-8+8n

=12+8n

The arithmetic equation is 12+8n

After Theo added to both sides of:

[tex] {(x + 2)}^{2} - 9 = - 5[/tex]

He got;

[tex]{(x + 2)}^{2} = 4[/tex]

Next he took the square root of both sides to get;

[tex]x + 2 = \pm \sqrt{4} [/tex]

When Theo simplifies, he will obtain:

[tex]x + 2 = \pm2[/tex]

Therefore the second option is correct.

[tex]-a^{3} b+13 a^{2} b^{2}-13 a b+5[/tex]

Step-by-step explanation:

Let x be the expression, we have to find must be subtracted from the given expression, to get the answer.

Now we have to combine the like terms, before that we have to move x from LHS to the RHS , so that we will get the required expression.

[tex]a^{2} b+6 a^{2} b^{2}-7 a b+4-x=-7 a^{2} b^{2}+2 a^{2} b+6 a b-1[/tex]

[tex]a^{3} b+6 a^{2} b^{2}-7 a b+4+7 a^{2} b^{2}-2 a^{3} b-6 a b+1=x[/tex]

Now arranging the like terms as,

[tex]\begin{array}{l}a^{3} b-2 a^{3} b+6 a^{2} b^{2}+7 a^{2} b^{2}-7 a b-6 a b+4+1=x \\-a^{3} b+13 a^{2} b^{2}-13 a b+5=x\end{array}[/tex]

So the expression is "[tex]-a^{3} b+13 a^{2} b^{2}-13 a b+5[/tex]"
