Solve for x
√(x - 2) = 0
​

Answers

Answer 1
Answer:

To solve for x, you need to isolate/get x by itself in the equation:

√(x-2) =0       Square ² both sides to get rid of the square root √

(√(x-2) )^2=(0)^2

x - 2 = 0           Add 2 on both sides

x - 2 + 2 = 0 + 2

x = 2

Do 3/7 and 7/3 represent the same length on a number line? Explain

Answers

No it does not  represent the same length on a number line.

What is number line?

A number line is a pictorial representation of numbers on a straight line.

here, we have,

3/7 and 7/3

now, 3/7 =0.42 <1

and, 7/3 = 2.33 >1

so, we get,

3/7 is below 1.

And 7/3 is an improper fraction and can be simplified to 1 1/3.

hence, No,  it does not  represent the same length on a number line.

A. 180°+z−w
B. 180°–z−w
C. w−z
D. 180°+w−z

Answers

Answer:

A. 180°+z−w

Step-by-step explanation:

We know that x  + w = 180  because they are same side exterior angles and a and b are parallel.

z=y  because they are alternate interior angles and a and b are parallel.

x  + w = 180

Solve for x by subtracting w from each side

x = 180-w

y =z

Lets find x+y

x+y

(180-w) +z

Rewriting

180+z-w

Answer:

A. 180º + z - w

Step-by-step explanation:

x + w = 180, because they are same side exterior angles, and are on opposite sides.

z = y, because if you move z down, then you will see that they overlap.

From x + w = 180, you can get x = 180 - w.

We are trying to find x + y in terms of w and z, so:

x = 180 - w

y = z

With that, you can assemble the expression, 180 - w + z.

If you re-arrange, you will get 180 + z - w.

Therefore, A is the answer.

Pansy measured the height of a window frame as 5.12 feet, but the actual height was 6 feet. What is the percentage of error in Pansy's measurement?A: 6.82
B: 6.88
C: 14.67
D: 11.12

Answers

The percentage error of the height of the table is: C. 14.67

Recall:

  • Percentage error can be calculated using the formula: (what was measured - the actual measurement) / actual measurement × 100%.

Thus:

The height that was measured = 5.12 feet

Actual measurement of the height = 6 feet

Percentage error = (6 - 5.12) / 6 × 100

Percentage error = 14.67

Learn more about percentage error here:

brainly.com/question/5493941
Percent error=100*(measurement-actual dimension)/actual dimension

pe=100(5.12-6)/6=-14.67%

So there is a 14.67% error.

A $220 tablet is on sale at half price for $110. You have a coupon for 20% off the sale price. If you use your coupon to buy the tablet, what percent of the original price will you pay?

Answers

ok so $220 is the original price
          $110 is the sale price
          20% is applicable for the sale price

$110×0.2   (20%=(20)/(100) = 0.2)
= $22

Original price × (n)/(100)  = 22
220 × (n)/(100) = 22
(n)/(100) = 0.1
n = 100×0.1
n=10%
We pay 10% of the original price.
Check: 220 × 0.1          (10%=(10)/(100) = 0.1)
           =$22
