Which Is Most Likely To Weigh 4 Tons?
A A Watermelon
B A Man
C A Clothes Dryer
D A Helicopter
(30 points)
The most likely object to weigh 4 tons will be Helicopter
The correct option is (D) Helicopter
What is ton in kg?1 ton = 1000 Kg
First, a watermelon weigh= 0.001 to 0.003 tons(i.e., 1-3 Kg)
then, A man weigh= 0.09 to 0.1 tons (i.e., 90 - 100kg)
A clothes dryer weigh= 0.07 to 0.09 tons (i.e., 70- 90 Kg)
lastly, a Helicopter weigh= 0.275- 56 tons (i.e., 275 - 56,000 Kg)
The closest is Helicopter weight 0.275- 56 tons

A student wrote the following equations:
3y + 6 = 2x
2y - 3x = 6
The lines represented by these equations are
(1) parallel
(2) the same line
(3) perpendicular
(4) intersecting, but not perpendicular
Using linear function concepts, it is found that the two lines can be classified as:
(4) intersecting, but not perpendicular.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The slope defines if the lines are parallel or perpendicular, as follows:
If they are parallel, they have the same slope.If they are perpendicular, the multiplication of the slopes is of -1.If the multiplication of -1, and the slopes are different, they are intersecting.In this problem, the lines in slope-intercept formula are:
[tex]y = \frac{2}{3}x - 2 \rightarrow = m = \frac{2}{3}[/tex]
[tex]y = \frac{3}{2}x + 3 \rightarrow m = \frac{3}{2}[/tex]
Then:
[tex]\frac{2}{3} \times \frac{3}{2} = 1[/tex]
So they are intersecting and not perpendicular, which means that option 4 is correct.

It is common knowledge that a fair coin lands heads up 50% of the time and tails up 50% of the time. For fair coins, a probability of 0 is assigned to the coin landing on its edge. But what if several coins were glued together? A teacher claims that if 10 pennies were glued together and flipped many times, the penny stack would land on heads 25% of the time, tails 25% of the time, and on its edge 50% of the time. To investigate this claim, a student glues 10 pennies together and flips the stack 200 times. The student would like to know if there is convincing evidence that the distribution differs from what the teacher claimed. What are the appropriate hypotheses?
H0: The distribution of flips is 25% heads, 25% tails, and 50% edge.
Ha: The distribution of flips is not 25% heads, 25% tails, and 50% edge.
H0: The distribution of flips is not 25% heads, 25% tails, and 50% edge.
Ha: The distribution of flips is 25% heads, 25% tails, and 50% edge.
H0: The penny stack will land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times.
Ha: The penny stack will not land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times.
H0: The penny stack will not land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times.
Ha: The penny stack will land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 tim
Answer:
The penny stack will land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times
Step-by-step explanation:
25% of 200=50
50% of 200=100

Cant find the answer
Answer:
Carter family = 25 hours
Davis family = 31 hours
Step-by-step explanation:
Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.
So combined:
x + y = 45 hours
and we are also told that:
40x + 15y = 1300 L
So we can do simultaneous equations to solve the problem.
With some rearranging, we can figure out that:
y= 45 - x
and by substituting that into the second equation:
40x + 15 (45 -x) = 40x + 675 - 15x = 1300L
25x = 1300 - 675
25x = 625
x = 25 = hours that the Carter family used their sprinkler
and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:
25 + y = 56
y = 31
The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

What is 1050 rounded to the nearest thousand?
Answer:
1100
Step-by-step explanation:
We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

A student solved the equation x2=132 to find the length of the diagonal of a square in centimeters which measurement is closer to x,the length of the diagonal of this square in centimeters.
The length 11 cm is closer to the length of the diagonal of this square in centimeters.
How to determine the value of x?The equation is given as:
x^2 = 132
Take the square root of both sides
x = √132
Evaluate the square root
x = 11.49
Approximate
x = 11
This means that 11 is closer to the length of the diagonal of this square in centimeters.

Step-by-step explanation:
As it is an isosceles triangle, two sides are equal (that's why we took two x)

What is the angle sum property?
A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
We are given that;
Angle = 110degree
Now,
x+x+110=180
2x+110=180
2x=180-110
2x=70
x=70/2
x=35
Therefore, by the angle sum property of triangles the answer will be 35degree.

The sum of all but one interior angle of a heptagon is 776°. What is the measure of the final interior angle? 42º 56º 124º 304º.
Answer:
124°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7 ( heptagon has 7 sides ) , then
sum = 180° × 5 = 900°
