It was a 5ft. by 5ft. sandbox. how many square feet would mr. potato head be able to walk inside the box?
25 square feet would mr. potato head be able to walk inside the box.
What is square ?A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.Each side of square is 90° .Given,
length and breadth of sandbox is 5 ft.
Now, We apply formula of area of square.
5 × 5 = 25 ft²
Therefore, 25 ft² would mr. potato head be able to walk inside the box.

I’m confused, can someone explain?
Answer:
-3 < x < 7
Step-by-step explanation:
The domain of a graph is all of the x-values that are included in the function. Since the graph is continuous (one connected line), you can determine the domain by identifying the x-values associated with the line's endpoints. These values are x = -3 and x = 7. Remember, the x-value located on a closed dot is not included in the domain. Therefore, the domain of the graph is -3 < x < 7.
If -8. min 19 are in an AP, find the values of m and n
Answer:
m = 1 and n = 10.
Step-by-step explanation:
I am assuming you mean -8, m , n, 19.
If they are in AP the 4 terms will have a common difference.
19 - (-8) = 19 + 8 = 27.
So the increase over 3 terms (from -8 to 19) is 27 so we have:
27 / 3 = 9
Therefore the common difference is 9 and the A P is
-8, 1, 10, 19.
Suppose that a classroom has 4 light bulbs. The probability that each individual light bulbs work is 0. 6. Suppose that each light bulb works independently of the other light bulbs. What is the probability that none of the 4 light bulbs work?.
Answer:
(0.4)⁴
Step-by-step explanation:
• The probability that each individual light bulbs work is :
1 - 0. 6 = 0.4
Then
•• the probability that none of the 4 light bulbs work is :
(0.4)×(0.4)×(0.4)×(0.4)
= (0.4)⁴
= 0.0256
You have a bag of marbles that has 12 red, 5 green, 6 yellow, and 4 blue. If you draw one at random. what is P(red)? (What would the percent of choosing red be)
[tex]|\Omega|=12+5+6+4=27\\|A|=12\\\\P(A)=\dfrac{12}{27}=\dfrac{4}{9}=44.4\%[/tex]
Answer: 44.44% approximately
Work Shown:
P(red) = (number of red)/(number total)
P(red) = (12 red)/(12 red + 5 green + 6 yellow + 4 blue)
P(red) = (12 red)/(27 total)
P(red) = 12/27
P(red) = 4/9
P(red) = 0.4444 approximately
P(red) = 44.44% approximately

Answer:
None of them.
Step-by-step explanation:
Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of [tex]y = kx + b[/tex]: [tex]k[/tex] is the slope or gradient of the line, [tex]b[/tex] is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient [tex]k[/tex].
[tex]2x + 4y = 16 \Leftrightarrow x + 2y = 8 \Leftrightarrow 2y = -x + 8 \Leftrightarrow y = - \frac{1}{2}x + 4[/tex]
Therefore, our line has [tex]k = - \frac{1}{2}[/tex] and [tex]b = 4[/tex] coefficients.
(A) [tex]k = 2, b = 5;[/tex]
(B) [tex]k = -1, b = 4;[/tex]
(С) [tex]k = -1, b = 8;[/tex]
(D) [tex]k = 2, b = 5;[/tex]
Recapitulating this: none of them have the same coefficient [tex]k[/tex], thus none of them suit us.

Do exponent laws apply all the time when simplifying variables?
It is true that exponent laws apply all the time when simplifying variables
How to determine the true statement?The laws of exponent state that:

The rabbits in the group with the diet of raw vegetables had significantly more growth that the other two groups. What conclusion can be drawn from this study?
Answer: That raw vegetables are better for the rabbit's growth than rabbit food.
Answer:
The rabbit food that was strictly a diet of raw vegetables is healthier for the rabbits.

The magnitude of the electrical force acting between a 2.4 × 10–8 c charge and a 1.8 × 10–6 c charge that are separated by 0.008 m is n, rounded to the tenths place.
The magnitude of the electrical force acting between both the given charges which are separated by 0.008 m is 6.07 N.
Given Charges 2.4*[tex]10^{-8} C[/tex] and 1.8 *[tex]10^{-6} C[/tex] that are separated by 0.008 m.
We have to find the magnitude of the electrical force acting between the charges. Magnitude is the property which determines the size of an object or process. Force is an influence that can change the direction of an object.
To find the magnitude we have to use Coulomb's law which says that
[tex]F_{E}=K*(q_{1}*q_{2}/d^{2}[/tex]
where K is Coulomb's constant whose value is [tex]8.9910^{9}Nm^{2} C^{2}[/tex].
[tex]q_{1}[/tex]=[tex]2.6*10^{-8} C[/tex] and
[tex]q_{2}=1.8*10^{-6} C[/tex] are the electric charges.
d=0.008m is the separation distance between the charges.
Putting the values in the given formula we get:
[tex]F_{E} =8.99(10)^{9}Nm^{2}/C^{2} *(2.4(10)^{-8}C(1.8(10)^{-6}C)/(0.008m)^{2}[/tex]
=6.07 N
Hence the magnitude of force acting between [tex]2.4*10^{-8} C[/tex] and [tex]1.8*10^{-6}C[/tex] is 6.07 N.

Glenn the owner of a hardware store originally paid $54.60 for 15 tool sets. at his year-end clearance sale he sold the last tool set for$24.00 how much money did he lose on the last tool set
The amount of money that Glenn lost on last tool set is $30.60.
Given sale value of 15 tool set 1 year before is $54.60 and the sale value of last tool at year end is $24.00 by Glenn.
Sale value is the price which we get by selling the good including the profit and cost of the product.
In this question it is given that 15 tools sets, it does not mean that 15 sets are sold.
Using the formula
Amount lose=Original amount paid- selling price.

If a/(b+c+d)=4/3 and a/(b+c)=3/5, find the value of d/a
Answer:
I did this quickly, so please check carefully.
d/a = -(11/12)
Step-by-step explanation:
a/(b+c+d)=4/3
3a = 4(b+c+d) [Cross multiply]
3a = 4((b+c)+d) [Note that b and c can be grouped as (b+c)]
---------------------
We can see the second equation also has a (b+c) group. Isolate it to one side:
a/(b+c)=3/5
5a = 3(b+c)
(b+c) = (5a/3)
------------------
Now use this definition of (b+c) in the first equation:
3a = 4((b+c)+d)
3a = 4((5a/3)+d) [Use the new value of (b+c), which is (5a/3)]
3a = 4(5a/3+3d/3)
3a = 4((5a + 3d)/3)
3a = (4/3)(5a + 3d)
3a = (20/3)a + 4d
9/3a = (20/3)a + 4d
-(11/3)a = 4d
4d = -(11/3)a
d = -(11/12)a
d/a = -(11/12)

2 six-sided dice, one colored green and one red, are released. Find the probability that : either the score on the green die is 1, or the score on the red die is 6, but not both.
The probability that either the score on the green die is 1 or the score on the red die is 6, but not both, is 11/36.
To find the probability that either the score on the green die is 1 or the score on the red die is 6 (but not both), we can break it down into two mutually exclusive events and then calculate their probabilities separately.
Event A: The score on the green die is 1.
Event B: The score on the red die is 6.
We need to find the probability of either event A or event B occurring but not both.
The probability of event A occurring is the probability of rolling a 1 on the green die.
Since each die is six-sided, the probability of rolling a 1 on the green die is 1/6.
The probability of event B occurring is the probability of rolling a 6 on the red die. Similarly, the probability of rolling a 6 on the red die is 1/6.
To calculate the probability of either event A or event B occurring but not both, we need to subtract the probability of both events occurring simultaneously from the sum of their individual probabilities.
The probability of both event A and event B occurring simultaneously is the product of their individual probabilities, which is (1/6) x (1/6) = 1/36.
So, the probability of either event A or event B occurring but not both is:
Probability = (Probability of event A) + (Probability of event B) - (Probability of both events occurring)
= (1/6) + (1/6) - (1/36)
= 6/36 + 6/36 - 1/36
= 11/36
Therefore, the probability is 11/36.

ProportionThe length marked x is the long side of the smallest triangle, and the short side of the middle-size triangle. The long side of the middle-size triangle is ...
