Answer:
Meters
Step-by-step explanation:
Meter is the standard unit of length in SI system and is normally used to measure houses and fields, therefore it is appropriate unit of measure for the dimensions of the playground.
A meter has 100 centimeters which is fairly small unit and cannot be used for dimensions of playground.
Similarly a Kilometer has 1000 meters and is used to measure long distances from one place to other which also makes it inappropriate unit for dimension of playground.
Hope that clarifies the answer.

Answer:
The answer is B.
Step-by-step explanation:
You simply just simplify the expression. When you do this you get x to the third, 2x squared, and 4x. I hope this helps!!
Answer:
B
Step-by-step explanation:
x*x*x=x^3 (x cubed)
x*x=x^2 (x squared)
We CAN'T add up x's here.
They're from different families.
So, B is correct:)
If a triangle has side lengths 7, 10, and 12, is it a right triangle??
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, [tex]a^2 + b^2 = c^2[/tex]
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, [tex]7^2 + b^2 = 12^2[/tex] or [tex]10^2 + b^2 = 12^2[/tex]
[tex]7^2 + b^2 = 12^2[/tex] ==> 49 + b^2 = 144 ==> b= [tex]\sqrt{95[/tex] ==> 9.746
b= 9.7, not 10.
[tex]10^2 + b^2 = 12^2[/tex] ==> 100 + b^2 = 144 ==> b = [tex]\sqrt{44[/tex] ==> 6.633
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!

A survey of Lakeview High School students found that 72% of the students had eaten breakfast that morning. If two students are chosen at random from a group of 100 students, what is the probability that at least one of them did not eat breakfast that morning?
Answer:
4.26 * 10^-12
Step-by-step explanation:
Usibg the binomial probability relation :
P(x =x) = nCx * p^x * q^(n-x)
Probability of success = probability of not eating = 1 - 0.72 = 0.28
p = 0.28
q = 1 - p = 0.72
Probability that atleast one out of 2 chosen did not eat breakfast :
P(x ≥ 1) = p(x = 1) + p(x = 2)
P(x ≥ 1) = (100C1 * 0.28^1 * 0.72^99) + (100C2 * 0.28^2 * 0.72^98)
= 4.26 * 10^-12
The Cooper family and the Reynolds family took a
vacation together. The Cooper family spent two-
thirds as much as the Reynolds family spent on the
vacation. If the Cooper family and the Reynolds
family spent $1,650 in all, how much did each family
spend?
Answer: well 2/3 of 1650 is 1100 so 1650-1100=550, so the cooper family spend $1100 and the reynolds family spent $550

WILL GIVE 100 POINTS TO WHOEVER ANSWER THIS CORRECTLY. In the similarity transformation of abc to def, abc was dilated by a scale factor of ?, reflected across the , and moved through the translation
Answer:
Dialated by a scale factor of two, reflected across the x axis, and transformed three units left
Step-by-step explanation:
The triangle was dilated by a scale factor of 2
What is similarity transformation?
One or more stiff transformations (such as reflection, rotation, and translation) followed by a dilation make up a similarity transformation. An image that resembles the original figure is produced when a figure undergoes a similarity transformation.
The following steps are followed while determining the similarities:
Step 1 is to identify the triangles' pairs of corresponding sides and pairs of matching angles. Step 2 Redraft the triangles with the same orientation and space between them. Step 3 Give the triangles names and create a similarity assertion,making sure to maintain the order of corresponding vertices.Solution:
Given:
AB=2, AC=1, BC=√5
DC=4, DF=2, EF=2√5
So scale factor is 4/2 = 2/1 = 2√5/√5 = 2
hence we get tha scale factor as 2.
Therefore, In the similarity transformation of abc to def, abc was dilated by a scale of 2.

Is the triangle a right triangle?
4 6 7
Is this a right triangle?
Answer:
No
Step-by-step explanation:
Given :-
A triangle with some side measure .The sides are 4 ,6,7.And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.
Pythagoras Theorem :-
In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .Here the two smallest sides are 4 & 6 .
Sum of Squares of 4 and 6 :-
[tex]:\implies[/tex] 4² + 6²
[tex]:\implies[/tex] 24 + 36
[tex]:\implies[/tex] 60
Square of 7 :-
[tex]:\implies[/tex] 7²
[tex]:\implies[/tex] 49
And :-
They aren't equal. So the triangle is not a right angled triangle .Hence the triangle is not a right angle triangle.
Answer:
No, this triangle is not a right triangle.
Step-by-step explanation:
Step 1: Definition(s)/explanations
This is a right triangle, so the Pythagorean Theorem applies.The Pythagorean Theorem states that the legs of the triangle, squared, must equal the hypotenuse, squared.The legs of the triangle are the sides that make the right angle.The hypotenuse is the longest side.Formula:
[tex]pt-a^2+b^2=c^2[/tex]
[tex]legs=a,b[/tex]
[tex]hypotenuse=c[/tex]
Step 2: Solve.
Now, I just plug the numbers into the formula.
[tex]a^2+b^2=c^2[/tex]
[tex]4^2+6^2=7^2[/tex]
[tex]16+36\neq 49[/tex]
If the legs of the triangle do not equal the hypotenuse, then the triangle cannot be a right triangle.
Step 3: Conclude.
Therefore, the triangle cannot be a right triangle.

Answer:
So option 4; [tex]\frac{35}{100}[/tex] is the correct option
Step-by-step explanation:
First, we need to convert [tex]\frac{2}{10}[/tex] so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10
[tex]\frac{2}{10} *\frac{10}{10} = \frac{20}{100}[/tex]
Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.
[tex]\frac{45}{100} + \frac{20}{100} = \frac{65}{100}[/tex]
Now that we have the total distance walked, we need to subtract that to 1 mile. [tex]1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}[/tex]
[tex]\frac{100}{100} -\frac{65}{100} = \frac{35}{100}[/tex]
So option 4; [tex]\frac{35}{100}[/tex] is the correct option

What are m<1 and m<2? Please help me
Answer:
Your answer is B
Step-by-step explanation:
The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.
Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.
Sorry if this is confusing the book will have better explanations than I can give.

Answer:
-0.4
Step-by-step explanation:
Identify the initial conditions y(0) and y'(0) for the vertical motion of an object, if the object is thrown downward at a velocity of 6 m/s from a height of 30m. (take the origin to be on the ground)
Answer:
The right solution is "y(0) = 30 m" and "y'(0) = -6 m/s²".
Step-by-step explanation:
Given,
Velocity,
u = -6 m/s
Height,
h = 30 m
Now,
By using shifting of origin, we get
⇒ [tex](y-30)=-6t+\frac{1}{2}(-9.8)t^2[/tex]
[tex]y-30=-6t-4.9t^2[/tex]
[tex]y=30-6t-4.9t^2[/tex]
hence,
The value of y(0) is:
y(0) = [tex]30-0-0[/tex]
= [tex]30 \ m[/tex]
The value of y'(0) is:
y'(t) = [tex]-6-9.8t[/tex]
y'(0) = [tex]-6 \ m/s^2[/tex]
