Milos is trying to prove that the sum of any two rational numbers is a rational number. His first steps are shownWhich is the best method Milos could use to continue?
Answers
Answer:
Answer is the first one
Step-by-step explanation:
Method A will be best to prove the condition, "the sum of any two rational numbers is a rational number."
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
It is given that, Milos is trying to prove that the sum of any two rational numbers is a rational number
Two rational numbers added together make rational number.As a result, adding two rationals is equivalent to adding two of these fractions, which will produce a new fraction with the same form since integers are closed under addition and multiplication. As a result, multiplying two rational numbers results in another rational number.
Thus method A will be best to prove the condition, "the sum of any two rational numbers is a rational number."

Answer:
111.46 units
Step-by-step explanation:
The right triangle has side lengths that are 1/√2 times the hypotenuse length, so each is (18√2)/(√2) = 18 units. The top is this length shorter than the bottom, so the total of all side lengths (CW from left) is ...
18 + (43 -18) +18√2 +43 = 86 +18√2 ≈ 111.46 units
A football team has a net yardage of −28 1/3
yards on a series of plays. The team needs a net yardage of 30 yards to get a first down. How many yards do they have to get on their next play to get a first down?
Answers
Answer: 58 1/3 yards
Step-by-step explanation:
From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.
The number of yards that they have to get on their next play to get a first down would be calculated as:
= 30 - -28 1/3
Note that minus × minus = plus
= 30 + 28 1/3
= 58 1/3 yards

Four families went out for lunch. The total food
bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.
Answers
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
If the total includes the tip, each family spent $34.25 on their food bill and $7.50 on the tip for the waitress.
If the total doesn't include the tip, but you want to include the tip, each family spent $49.25 on the food bill AND tip.
167/4 = 41.25
(167-30)/4 = 34.25
30/4 = 7.50
(167+30)/4 = 49.25
Tim goes on a car journey.
for the first 15 minutes his average speed is 40 mph
he then stops for 25 minutes
he then completes the journey at an average speed of 45mph
the total journey time is 1 hour.
A) draw a distance time graph for his journey?
B) what is the average speed for the whole journey?
Answers
Answer:
See attached picture ;
25 miles / hour
Step-by-step explanation:
First phase :
Travel time = 15 minutes
Average speed = 40 mph
Distance covered = speed * time
Distance covered = 40 * (15/60) = 10 miles
Second phase :
25 minutes stop
Third phase :
Average speed = 40 mph
Distance covered = speed * time
Travel time = 60 - (25 + 15) = 20 minutes
Distance covered = 45 * (20/60) = 15 miles
Average speed for the journey :
Total distance / total time taken
= (10 miles + 15 miles) / 1 hour
= 25 miles / hour

Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats. Which equation gives an area A as a function of the width w of the enclosure?
A(w)=180−w2
A(w)=360−w2
A(w)=180w−w2
A(w)=360w−2w2
Answers
Answer:
A(w) = 180w-w²
Step-by-step explanation:
Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats.
It means that the perimeter of the rectangle is 360 feet
The formula for the perimeter of a rectangular shape is given by :
P = 2(l+w)
l is length and w is width
ATQ,
2(l+w) = 360
(l+w) =180
l = 180 -w .....(1)
The formula for the area of a rectangle is given by :
A = lw
Put the value of l form equation (1).
A = (180-w)w
A(w) = 180w-w²
Hence, the correct option is (c).

The slope of the line that passes through (2, 3)(5, 9) is 2
Slope formula is describe below:m = y₂ - y₁ / x₂ - x₁Therefore, the slope of the line that passes through the points (2, 3)(5, 9) can be found as follows;
y₁ = 3
y₂ = 9
x₁ = 2
x₂ = 5
m = 9 - 3 / 5 - 2
m = 6 / 3
m = 2
slope = 2
Therefore, the slope of the line that passes through (2, 3)(5, 9) is 2
