Answers
Answer: B.)determine the number of steps needed
Step-by-step explanation:
A geometric proof of a geometric statement includes the following steps :-
a) Evaluate the given statement.
b) Look carefully at the figure related to the geometric statement .
c) Create a plan to express the proof.
d)Then use definitions, given axioms, postulates and previously proved theorems to write a logical explanation approaches to the conclusion.
Hence, the step is not important to develop a plan for a geometric proof: is "determine the number of steps needed" .

Given that BC = 7, AB = 17.89, and C is between A and B, what is the length of ?
Answers
then you have
AB = 17.89 ..... this is the length of the whole line
BC is a part of the line = 7
therefore the length of the other part = 17.89 - 7
= 10.89
You know that the distance from A to b is 17.89 and the distance from b to c is 7. So the length from a to c is the whole distance(a to b) subtracted by a portion of the distance(b to c) giving us 10.89

Clara estimates that the length of a hiking trail is 10 km. She later learns that its actual length is 12 km.
What is the percent error in Clara's estimate?
.002%
8.0%
0.2%
11.5%
Answers
Experimental value = 10 km
accepted value = 12 km
Step 1: Deduct the accepted value from the experimental value.
10 km – 12km = -2 km
Step 2: Take the absolute value of step 1
|--2km| = 2km
Step 3: Divide that answer by the accepted value. 2km/10km = 0.2%

Um navio esta situado exatamente a 10 milhas a leste de um ponto A. Um observador, situado exatamente a sul do navio, ve o ponto A sob um angulo de 40°. Qual a distância entre o observador e o navio?
Answers
Com estes 3 pontos formamos um triangulo.
O angulo OAN vale 40º
O lado AN vale 10 milhas
O que queremos saber é a distância entre o observador e o navio: lado NO
2) Para isso calculamos a tangente deste angulo: tg 40º= angulo oposto/ angulo adjacente.
angulo oposto é o NO e o lado adjacente ao angulo é o AN que vale 10
Se fores à calculadora vês que tg40º é 0,83.
0,83= angulo oposto/ 10
ang oposto= 8,3 milhas
o observador e o navio estao a 8,3 milhas de distancia

Triangle A B C with angle A measuring thirty degrees, angle B measuring seventy degrees and angle C marked x
Answers
Answer: In a triangle, the sum of the 3 angles is always equal to 180°
Then if the angle A is equal to 30°, the angle B is equal to 70°, what is the angle C?
if x is the angle C, and using the first statement, we got:
30° + 70° + x = 180°
100° + x = 180°
x = 180° - 100° = 80°
So the angle of C is equal to 80°.

Keith's florists has 15 delivery trucks, used mainly to deliver flowers and flower arrangements in the greenville, south carolina, area. of these 15 trucks, 5 have brake problems. a sample of 4 trucks is randomly selected. what is the probability that 2 of those tested have defective brakes?
Answers
The answer is 0.2963.
Answer:
Hence, the probability is:
0.296
Step-by-step explanation:
This can be solved with the help of the binomial probability as:
[tex]P(x=r)=n_C_rp^r(1-p)^{n-r}[/tex]
where n denote the quantity which are chosen.
r denote the quantity whose probability is to be determined or success.
and p denote the probability of success.
with n=4 since 4 trucks are randomly selected.
p=5/15=1/3 ( As 5 have brake problems out of total 15 trucks)
1-p=10/15=2/3
r=2 ( since we are asked to find the probability that 2 of those tested have defective brakes)
Hence, the probability is:
[tex]P(x=2)=4_C_2(\dfrac{1}{3})^2(\dfrac{2}{3})^2\\\\\\P(x=2)=\dfrac{4!}{2!\times (4-2)!}\times \dfrac{1}{9}\times \dfrac{4}{9}\\\\\\P(x=2)=0.296[/tex]
Hence, the probability is:
0.296

On a given blueprint, 1 inch=12 feet. if the dimensiopns of a recreation room on the blueprint are 2 onches x 1.75 inches. what are its actual measurements
Answers
Unit conversion is the conversion of one unit to another unit with its standard conversion.
The actual dimension of the recreation room is 24 feet x 21 feet.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1m = 100 cm
1 hour - 60 minutes
We have,
Recreation room dimension on the blueprint:
= 2 inches x 1.75 inches ______(A)
Scale factor:
1 inch = 12 feet
The actual dimension of the recreational room:
1 inch = 12 feet
Multiply 2 on both sides.
2 inches = 24 feet _____(1)
1 inch = 12 feet
Multiply 1.75 on both sides.
1.75 inches = 1.75 x 12 feet
1.75 inches = 21 feet ______(2)
From (1) and (2) and (A) we get,
= 2 inches x 1.75 inches
= 24 feet x 21 feet
Thus,
The actual dimension of the recreation room is 24 feet x 21 feet.

The area of a rectangle is 45 square inches. The rectangle is 9 inches long. How wide is the rectangle?
A. 5 inches
B. 36 inches
C. 27 inches
D. 3 inches
Answers
Final answer:
To find the width of a rectangle with an area of 45 square inches and a length of 9 inches, divide the area by the length, resulting in a width of 5 inches (Option A).
Explanation:
The area of a rectangle can be calculated by multiplying its length by its width. In this case, we know the area is 45 square inches and the length is 9 inches. To find the width, we divide the area by the length.
Width = Area ÷ Length = 45 sq in ÷ 9 in = 5 in
Therefore, the width of the rectangle is 5 inches, which corresponds to option A.

If he drove the same distance every week, which equation shows how far he drove each week (d)?
A.
d = 6 ÷ 1080
B.
d = 1080 – 6
C.
d = 1080 • 6
D.
d = 1080 ÷ 6
Answers
All you have to do is take the distance she drove and divide it by how many weeks it took.
Mr. Guzman drove 1080 miles in 6 weeks. To find the distance driven each week, use the equation d = 1080 ÷ 6, which equals 180 miles per week. Therefore, the correct equation is option D.
Mr. Guzman drove 1080 miles in 6 weeks. We need to find out how far he drove each week if he drove the same distance every week.
Identify the Total Distance Driven: 1080 milesIdentify the Total Time Period: 6 weeksSet Up the Equation: Since Mr. Guzman drove the same distance every week, we use the formula:
d = Total Distance / Total Time.Substitute Known Values:
d = 1080 ÷ 6Calculate the Result:
d = 180 miles per weekThe correct equation that shows how far Mr. Guzman drove each week is d = 1080 ÷ 6, which corresponds to option D.
