True or False
All lines are congruent to one another.
Answers
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.

Terry needs to carry a pole that
is 10 feet tall through a
rectangular doorway that
measures 6 feet by q feet. Will
the pole fit diagonally through the
doorway? Explain.
6 ft
9 ft
Answers
Answer:
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.
Step-by-step explanation:
Using the Pythagorean Theorem, ([tex]a^2+b^2=c^2[/tex] ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.
Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:
[tex]6^2+9^2=c^2[/tex]
[tex]36+81=c^2[/tex]
[tex]117=c^2[/tex]
Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.
[tex]\sqrt{117} =10.8[/tex]
[tex]10.8=c[/tex]
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.

Which of the following is a reciprocal of 3/9?
Answers
Answer:
It would be 3.
Step-by-step explanation:
So, a reciprocal is basically just flipping over the numerator and the denominator of a fraction. Therefore:
3/9 ---> 9/3
The reciprocal of the fraction number in the simplified form will be 3.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The fraction number is given below.
⇒ 3 / 9
Simplify the fraction number, then we have
⇒ 3 / 9
⇒ 1 / 3
The reciprocal of the fraction number will be given as,
⇒ 1 / (1/3)
⇒ 3
The reciprocal of the fraction number in the simplified form will be 3.

Jason wants to earn at least $250 each week working during the summer.
Jason earns $6.00 an hour babysitting.
Jason earns $7.75 an hour working at a store.
He can work no more than 40 hours each week.
Let b equal hours of babysitting, and s equal hours working at the store.
Which system of inequalities models the constraints?
6.00b + 7.75s ≤ 40
b + s ≥ 250
6.00b + 7.75s ≥ 250
b + s ≤ 40
6.00b + 7.75s ≥ 40
b + s ≥ 250
6.00b + 7.75s ≤ 250
b + s ≤ 40
Answers
Answer:
6.00b + 7.75s ≥ 250
b + s ≤ 40
Step-by-step explanation:
6.00b + 7.75s ≥ 250---this represents how much he will make
b + s ≤ 40---these are his hours. B+S are his hours, and they can't be greater than 40 hrs, so ≤.
