Answers
Answer:
The first yes, the second no.
Step-by-step explanation:
Proportional means they follow a constant proportion. In the first example, 1 hr is 4.5 ft, so the constant is 4.5, which means that everything in the top line multiplied by 4.5 should equal the bottom line. 2*4.5=9, 3*4.5=13.5, if you check it it all works out. But on the second problem, 2 hrs is 20 ft, which means that the constant should be 10, because 2/2 is 1 and 20/2 is 10, but 4*10 does not equal 30, it equals 40, so right off the bat we know it’s not proportional.

Answer:
Step-by-step explanation:
(2.54 × \(10^{19}\)) + (3.218 × \(10^{17}\)

Hope this was helpful for you!!
The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
Given the digits are
2.54 x 10¹⁹ and 3.218 x 10¹⁷
Now in order to sum we need to make an equal exponent of 10
So,
2.54 x 10¹⁹ = 254 x 10¹⁷
Now, Summation
254 x 10¹⁷ + 3.218 x 10¹⁷
257.218 x 10¹⁷ = 2.57218 x 10¹⁹
Hence "The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct".

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answers
74 meters
Step-by-step explanation:
The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.
2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=3, y1=2, x2=0, y2=−1.
Plug the given values into the formula for slope: m=(−1)−(2)(0)−(3)=−3−3=1.
Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).
b=2−(1)⋅(3)=−1.
Finally, the equation of the line can be written in the form y=mx+b.
y=x−1.
Answer:
The slope of the line is m=1.
The equation of the line in the slope-intercept form is y=x−1.
The equation of the line in the point-slope form is y−2=1(x−3).
The equation of the line in the point-slope form is y+1=1x.
The general equation of the line is x−y−1=0.

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the number of triangles be = 4 triangles
The height of the triangle = 4 cm
The base of the triangle = 5cm
The side length of the square a = 5 cm
So , the area of the figure A = area of square + 4 ( area of triangles )
Area of triangle = ( 1/2 ) x height x base
Area of triangle = ( 1/2 ) x 4 x 5
Area of triangle = 10 cm²
The area of 4 triangles = 4 x 10 = 40 cm²
Now , the area of square = a²
Area of square = 5² = 25 cm²
Now , the area of the figure A = 40 + 25
Area of the figure A = 65 cm²
Hence , the area of the figure is 65 cm²

Step-by-step explanation
#1 apply the exponet rule a -¹ = 1/a
(2/3) ^-1 =1/2/3 Apply the fraction rule then you get 3/2
#2 (4/5)^-2 = 1/(4/5)^2 ,
(4/5)^2= 16/25
then you get your answer 25/16
#3 ((x/x^2)^3)^2 =(x/x^2) 3times 2
multiply the numbers 3 times 2 = 6
= (x/x^2)^6
(x/x^2)^6= x^6/(x^2)^6
simplify (x^2)^6: x^12
x^6/x^12(fraction)
x^6/x^12= 1/x^12-6

Answer:
1/32
Step-by-step explanation:
The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.
Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:
Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)
= (1/6) x (1/6)
= 1/36
Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

Answer:

Step-by-step explanation:
Lets start with an expression for how many yards Gary threw. Since y is the variable given in the problem, we'll use that.
Yards Gary threw = y
We also know that Pat threw 5 more than twice the yards Gary did. First, we multiply Gary's yards by 2, then add 5 more. We end up with the expression:
Yards Pat threw = 2y+5
Ben wants to go fishing on the lake
A boat rents for $12 per hour, and a rod and reel rent for $20 per day.
If Ben wants to spend no more than $80, how many hours can he soend fishing on the boat
Answers
Answer: Ben can only rent the boat for 5 hours.
Step-by-step explanation:
You have to set up an equation. It would be 20 + 12h = 80
20+12x=80
12x=80-20
Then divide both sides 12x=60
And you get 5
Now if you wanna include the rod and reel, Ben can spend 29 hours (24 hours from the rod and reel, and 5 hours on the boat) Which all adds up to 80
