Shirley thought there were 25 students in her math class, but there were actually 27 students. What is her percent error?

Answers

Answer 1

27-25=2

so her absolute error was 2 students

divide the answer by 100 to get the percentage error.

percentage error = absolute error/ 100

2/100=0.02%

therefore her percentage error is 0.02%.

Answer:

  use the definition of isosceles to claim congruent sides (or angles), and use the shared side and the fact that angles at C are 90°. Claim HL or AAS congruence.

Step-by-step explanation:

Approach to the problem

Of course, AC is congruent to itself. AC ⊥ BD means ∠ACB ≅ ∠ACD ≅ 90°. Then the fact that the larger triangle is isosceles lets you claim angle B = angle D, or AB = AD (or both).

If you use the congruence of angles, you can claim AAS congruence for the triangles. If you use the congruence of sides, you can claim HL congruence for the right triangles.

Specifics

1. ∠ACB ≅ ∠ACD (= 90°) . . . . definition of perpendicular

2. AB ≅ AD . . . . definition of isosceles triangle

3. AC ≅ AC . . . . reflexive property of congruence

4. ∆BAC ≅ ∆DAC . . . . HL congruence theorem

Arman is building a bench. The bench comes out from the wall and there is a brace supporting the bench as shown in the figure below. The angle created between the wall and the brace is 52.6°. Which equation can be used to solve for the missing angle?

Answers

Answer:

x+ 52.6°.+90=180--------1

Step-by-step explanation:

Hey!!!, we can imagine the right angles triangle formed. ok, let imagine it this way.

1. the bench comes out perpendicular to the wall

2. The brace forms an angel of 52.6

3. then the angle formed between the bench and the wall is  90°.

we know that the sum of angles in a triangles is  180°

let the third angle be x

Therefore the equation to find the missing angle is

x+ 52.6°.+90=180---------------1

x+142.6=180

x=180-142.6

x=37.4°

Answers

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

1/2x + 13 = 9

Step 2: Solve for x

Subtract 13 on both sides: 1/2x = -4Multiply both sides by 2: x = -8

Step 3: Check

Plug in x to verify it's a solution.

1/2(-8) + 13 = 9

-4 + 13 = 9

9 = 9

Answer:

-8

Step-by-step explanation:

you use inverse operation

meaning opposite signs

subtract -13 from 13 cross it out

subtract 13 from 9

you get 1/2x=-4

divide 1/2 on both sides

-4 divided by 1/2 =-8

Write an equation for a line parallel to y =4x + 3 and passing through the point (3,-11).
HELP

Answers

Answer:

y = -4x + 1

Step-by-step explanation:

y = -4x + 3

Passing through point (3, -11)

y = mx + b

-11 = -4(3) + b

-11 = -12 + b

b = 1

Use b from above to make new equation of line going through given point (3, -11)

y = -4x + 1

Original: y = -4x + 3

One that pass through given point: y = -4x + 1

The slope is -4 in both equations so they are parallel.

Caroline wants to buy a pair of shoes that has an original price of $80.00. She has a coupon for a 40% discount off of the original price. Her state charges an 8% sales tax on the discounted price. What is the final cost for Carolines shoes?​

Answers

Answer:

$34.56

Step-by-step explanation:

Let's start by findig the discount price.

40% off? Nice. 40% of 80 is 32 so the discount price would be $32.00.

Then there is the sales tax. 8% on the discounted price. So 108% of 32 is the total answer.

If you do it correctly, the price would be $34.56.

Suppose that Prolog facts are used to define the pred- icates mother(M, Y) and father(F, X), which represent that M is the mother of Y and F is the father of X, re- spectively. Give a Prolog rule to define the predicate grandfather(X, Y), which represents that X is the grand- father of Y. [Hint: You can write a disjunction in Prolog either by using a semicolon to separate predicates or by putting these predicates on separate lines.]

Answers

Answer and Explanation:

The Prolog rule expresses that logical implication (:-) describes the relationship between facts.

Prolog expressions are containing truth-functional symbols, which have the same intervention as in predicate calculus.

For example:  

English Predicate calculus prolog

and ^ ,

or v ;

By using information, given in the question,

We can make prolog:

Grandfather(X, Y)  :-mother(M,Y), father(X,M); father (F, Y), father(X,F)

Prolog (:- ) means define,

Prolog (,) represents a conjunction

And

Prolog (;) represent a disjunction
