Given that, the total number of students in seventh and eighth grade combined is 584.
The number of students in seventh grade= 5/8 of the total number of students.
[tex]=\frac 5 8 \times 584=365[/tex]
As 4/5 of the total seventh-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac 4 5 \times 365=292[/tex]
The number of students in the eighth grade 3/8 of the total number of students.
[tex]=\frac 3 8 \times 584=219[/tex]
As 7/8 of the total eighth-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac78 \times 219=191.625.[/tex]
The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.
Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined
=292+191.625
=483.625 (mathematically)
Again, in real life, the fractional value of the total number of students is not possible.
Answer:
Given that, the total number of students in seventh and eighth grade combined is 584.

Answer:
C) 6^6
Step-by-step explanation:
When we divide same base numbers with different exponents, the answer will be the base raised to the power of the difference of those exponents:
The rule is: x^a/x^b=x^(a-b)
In this case: 6^9/6^3=6^(9-3)=6^6=46656
Therefore, C is the correct answer

Answer:
The difference in cost per mile is $0.94.
Step-by-step explanation:
Uber
7x = 20.37
x = $2.91 per mile
Lyft
4y = 15.4
y = $3.85 per mile
3.85 - 2.91 = 0.94
Hello.
To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.
20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)
15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)
3.85 - 2.91 = 0.94
The difference in cost per mile is $0.94

Write an equation for a line that is parallel to y = -4x + 2 and passes through the point (-2, 5).
Answer:
y = -4x - 3
Step-by-step explanation:
y = -4x + 2
Substitue Y and X and turn 2 into b(or y intercept)
5 = -4(-2) + b
Solve for b
5 = 8 + b: subtract 8 from both sides
-3 = b
substitute for 2 with same slope(to keep parrallel)
y = -4x - 3

Step-by-step explanation:
A screwdriver is dropped from the top of an elevator shaft. Exactly 6.0 seconds later, the sound of the screwdriver hitting bottom is heard. How deep is the shaft? Hint: The distance that a dropped object falls in t seconds is represented by the formula s = 16t2. The speed of sound is 1100 ft/sec. The shaft is approximately (Round to the nearest tenth.) | feet deep.
Answer:
Step-by-step explanation:
Using the equation of motion
S = ut+1/2gt²
S is the height of fall
g is the acceleration due to gravity = 9.81m/s²
u is the initial velocity = 0m/s
t is the time = 6s
Substitute in the formula;
S = 0+1/2(9.81)×6²
S = 4.905×36
S = 176.58m
The shaft is 176.58m deep
Given the expression for distance
S = 16t²
Velocity V = dS/dt
V = 32t
Given v = 1100
1100 = 32t
t = 1100/32
t = 34.375secs
Substitute t = 34.375 into S = 16t²
S = 16(34.375)²
S = 18,906.25ft

Step-by-step explanation:
Substitute the values of n 1,2,3,4 and see if the output is the corresponding number in the sequence.
n = 1 2 3 4
-5 -3.8 -2.6 -1.4
an= 1.2 (n-1) -5 the n-1 needs to be a number multiplied by 1.2 produces a number added to -5 results in the number in the sequence.
a1=1.2(1-1) -5 a= 1.2(0) -5 a= -5
a2 1.2 (2-1) -5 a= 1.2(1) -5 a= -1.2 -5 a= -3.8
a3 1.2 (3-1) -5 a= 1.2(2) -5 a= -2.4 -5 a= -2.6
a4 1.2 (4-1) -5 a= 1.2(3) -5 a= -3.6 -5 a= -1.4

Harry's dog weighs 10 3/8 pounds. What is the weight of Harry's dog written as a decimal?
Answer:
10.375
Step-by-step explanation:
You can tell that 10 is going to be before the decimal because it's already a whole number, so all you have to do is figure out what 3/8 is as a decimal! In case you didn't know, to change a fraction to a decimal, you divide the numerator (the top number) by the denominator (the bottom number). In this case, you need to divide 3, the numerator, by 8, the denominator. 3/8 = 0.375.
So, put the 10 in front of the decimal point and you're done...the answer would be 10.375!

Joe lives in a city that is 15 feet below sea level. How could he
represent his elevation as an integer?
Answer:
He could say that he is -15 feet as seen from the sea level
The given statement can be represented in an integer as -15.
Given that, Joe lives in a city that is 15 feet below sea level.
We need to find how could he represent his elevation as an integer
How will you represent a sea level as an integer?Whole numbers less than zero are called negative integers (-). These numbers are to the left of zero on the number line. Zero is neutral. It is neither positive nor negative.
Now, 15 feet below sea level can be represented as -15.
Therefore, the given statement can be represented in an integer as -15.

Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).
Step-by-step explanation:
Hey there!
The given midpoint is; X(-8,4) and G(2,-9).
To find: H
Now; You need to use formula for midpoint.
[tex]midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
Put all values.
[tex]( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )[/tex]
As they are equal, their corresponding elements are equal.
[tex] - 8 = \frac{2 + x}{2} [/tex]
[tex] - 16 - 2 = x[/tex]
x = -18
[tex]4 = \frac{ - 9 + y}{2} [/tex]
[tex]4 \times 2 = - 9 + y[/tex]
[tex]8 + 9 = y[/tex]
[tex]y = 17[/tex]
Therefore, y = 17.
Therefore, H =( -18,17).

the relationship between NP and PQ if point P is midpoint of NQ
Answer:
NP=PQ
Step-by-step explanation:
p is MIDpoint of NQ so basically distance of N to P is equal to distance of P to Q
The relationship between NP and PQ if point P is the midpoint of NQ is:
- NP + PQ = NQ
- 1/2 x NQ = NP = PQ
Given,
P is the midpoint of NQ.
We need to find the relationship between NP and PQ if point P is the midpoint of NQ
What does it mean to have a midpoint?The midpoint between two points in a line always divides the line into two equal parts.
The sum of the divided parts is always equal to the original line.
Half of the original line is equal to each part.
Example:
A_____B_____C
B is the midpoint.
We have,
AC = AB + BC
1/2 x AC = AB = BC
We have,
P is the midpoint of NQ
Now,
N______P______Q
Since P is the midpoint we can say that,
NP + PQ = NQ
And,
1/2 x NQ = NP = PQ
Thus the relationship between NP and PQ if point P is the midpoint of NQ is:
- NP + PQ = NQ
- 1/2 x NQ = NP = PQ

1.) C
2.) C
3.) A
5.) B
Step by-step explanation:
1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!
2.) to get to 7 from -7 you would have to take 7 units to get there.
3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.
5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .
