Answer:

2.4*10^6

Step-by-step explanation:

R = x^2 / y

R = [tex]\frac{(3.8 * 10^5)^2}{(5.9*10^4)}[/tex]

R = [tex]\frac{1.444*10^{11} }{5.9*10^{4} }[/tex]

R= 2447457.627

to find out what to round of to , you look at the value of x and y

both x and y are rounded of to 2 significant figures. hence for R you should use the same

R = 2447457.627

R = 2.447457627 * 10^6

to 2 sf

R = 2.4 *10^6

Answer:

Step-by-step explanation:

a variable can have any value depending upon the equation

for example,

in 2x + 3 = 11

2x = 11 - 3

2x = 8

x = 8 / 2

x = 4

Hope this helps

plz mark as brainliest!!!!!!!

Step-by-step explanation:

Hey there!

Variables have the unknown value.

If you want to find or know value from the equation easily, you have to simply solve the equation.

For your example;

2x+3=11

Now, solve it to get value of variable 'x'.

2x = 11-3

2x = 8

[tex]x = \frac{8}{2} [/tex]

Therefore the value of variable 'x' is 4.

Hope it helps...

Answer:

8

Step-by-step explanation:

3(4)+(5)(4)-2(12)

then solve

12+20-24=8

Answer of the given expression 3c + bc -2a is equals to 8.

" Variables is that quantity which gets vary or change as per the situation assigned to it."

According to the question,

Given,

a = 12  , b = 5 , and c=4

Substitute the values of the given variable in the equation we get,

3c +bc - 2a

=3(4) + (5)(4) -2(12)

= 12 +20 -24

=32-24

=8

Hence, value of 3c + bc -2a is equals to 8

Answer:

When solving, Jacob did not distribute properly.

Explanation:

Let's talk about 5(x + 2). The correct distribution would be 5x + 10. Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10, however it stayed as 2.

Jacob should be more careful when distributing, and make sure to distribute into EVERY term inside the parentheses.

The coordinates of point B of the line segment are (-3, -7).

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.

The formula to find the midpoint of line segment is (x, y) = [(x₁+x₂)/2, (y₁+y₂)/2]

Given that, the midpoint of AB is M (-1, -2).

The coordinates of A are (1,3).

Let the coordinates of point B are (x, y)

Here, (-1, -2) = [(1+x)/2, (3+y)/2)

-1=(1+x)/2 and -2=(3+y)/2

-2=1+x and -4=3+y

-3=x and -7=y

The coordinates of point B are (-3, -7)

Therefore, the coordinates of point B of the line segment are (-3, -7).

Answer:

x = 3

Step-by-step explanation:

For this problem, it's important to understand what an angle bisector is.  An angle bisector is simply a line that splits an angle into two equal portions.  In this problem, <ATS is bisected by TR which gives us <ATR = <RTS = 1/2 <ATS.

Let's use this information to solve our equation to find x.

m<RTS = 1/2 m<ATS

17x - 5 = (1/2) (28x + 8)

17x - 5 = (1/2)(28x) + (1/2)(8)

17x - 5 = 14x + 4

17x - 14x - 5 = 14x - 14x + 4

3x - 5 = 4

3x - 5 + 5 = 4 + 5

3x = 9

3x * 1/3 = 9 * 1/3

x = 3

Hence, we have found the value of x to be 3.

Answer:

-1.875

Step-by-step explanation:

1. Write the problem: -2(5x + 8) = 14 + 6x

2. Multiply -2 by 5 and 8 to get: -10x - 16 = 14 + 6x

3. Combine like terms: -16x - 16 = 14

4. Repeat step 3: -16x = 30

5. Divide -16 by 30 to get the answer which is -1.875.

Answer:

8x^4y^2

Step-by-step explanation:

Given parameters:

Measured length = 6.8inches

Actual length  = 6.5 inches

Unknown parameter is the percentage error

Errors introduce uncertainty into a reading. Often times measurement errors are incurred in a process due to diverse reasons. This error can be due to the problems with the measuring device, incorrect reporting of measured values and also, the scientist can be at fault.

Deviation from the actual measurement leads to the concept of accuracy.

To solve this problem, we need to find the absolute error;

  Absolute error = | Measured length - Actual length|

Input the variables given and solve;

    Absolute error  = | 6.8 - 6.5|  = 0.3 inches

Now, let us find the percentage error;

  Percentage error  = [tex]\frac{Absolute error}{Actual length} x 100[/tex]

 Input the parameters and solve;

      Percentage error  = [tex]\frac{0.3}{6.5} x 100[/tex]   = 4.615%

   To the nearest tenth percent = 4.6%

Therefore, the percentage error to the nearest tenth percent = 4.6%
