An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?

Answers

Answer 1

Answer:

3.33%

Step-by-step explanation:

60 = theoretical/actual degree measure

62 = experimental/calculated degree measure

% error = (|actual - calculated|/actual)*100

In words, the absolute value of the actual value minus the calculated value is first calculated. Then, divide the difference by the actual value that you should have obtained. Since you want this converted to a percent, multiply the decimal value of your quotient by 100.

Three significant figures is 3.33 because none of these numbers are leading or trailing zeros. If you count how many numbers (that are not leading or trailing zeros) the value 3.33 has, you'll find 3 significant figures, which is why your final answer should be 3.33%.

Answers

Answer:  C) 27

Explanation:

The scale factor 3/2 is the same as 1.5

We multiply this by the perimeter 18 to get 18*1.5 = 27

The perimeter is 27 units.

This trick works because we're multiplying each length by 1.5, so ultimately the perimeter is multiplied by this same scale factor.

Answer:

  2a. (360x +495)/(8x +11) = 45

  2b. 2((8x+11) +45) = 16x +112

Step-by-step explanation:

a) The area is the product of length and width.

  A = LW

We are given ...

  W = 8x +11

  A = 360x +495

The value of length can be found by solving for L:

  L = A/W

  L = (360x +495)/(8x +11)

The long-division solution to this is shown in the attachment.

  L = 45 . . . . simplified expression for length

__

b) The perimeter of the tank is twice the sum of length and width:

  P = 2(L +W)

Substituting the values for L and W, this is ..

  P = 2(45 +(8x +11)) . . . . expression for length of edge seal

  P = 2(8x +56)

  P = 16x + 112 . . . . . . simplified expression for seal length

70° ? 127° 146° Can I get some help with this?​

Answers

Answer:

93 degrees

Step-by-step explanation:

First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,

180-127= 53.

180-146=34.

Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.

x=93

Now, just flip the angle around and "?" = 93 degrees.

Answer:  93 degrees

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

Explanation:

Let x be the question mark angle we want to find.

Let y be adjacent to the 127 degree angle

Let z be adjacent to the 146 degree angle.

Refer to the diagram below.

Note that in the diagram, I have a second copy of 'x' because the two x angles are vertical angles. Vertical angles are always congruent.

Let's find angle y

127+y = 180

y = 180-127

y = 53

Do the same for angle z

z+146 = 180

z = 180-146

z = 34

Then notice how,

x+y+z = 180

x+53+34

x+87 = 180

x = 180-87

x = 93

The polynomial, 3x - 4 + 5x², is a trinomial with a degree of 2.

What is a polynomial?

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given:

We have the polynomial,

3x - 4 + 5x²

To find the degree of a polynomial:

We take the highest powered variable, and the order of that variable is equal to the degree of the polynomial.

Here, the highest power is 2.

So, the degree is 2.

And the polynomial has three terms.

So, the polynomial is trinomial.

Therefore, it is a trinomial with a degree of 2.

a + b = 20 ( square both sides )

(a + b)² = 20² , that is

a² + b² + 2ab = 400 ( substitute ab = 75 )

a² + b² + 2(75) = 400

a² + b² + 150 = 400 ( subtract 150 from both sides )

Sandi got 1/1/4 pounds of gummy worms if she left the store with 3 pounds of gunmys worms and skittles ,how many pounds of skittles did she get

Answers

Answer:

1 3/4 lbs of skittles

Step-by-step explanation:

Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs

Complex way:

(I'm assuming "1/1/4" means "1 1/4")

This is simply ~Subtraction~

The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).

So we need to know what added to 1 1/4 equals 3.

Equation: t= 1 1/4 + s

Equation: t= 1 1/4 + s

We can replace (t) with 3 because we know this variable.

1. 3= 1 1/4 + s

To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation

2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s

The right side cancels out = 0 and the left = 1 3/4

3. 1 3/4= s

Flip it around for the traditional view

4. s = 1 3/4

In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)
