Michael, Nate, Ben, and Andrew are running a relay race. In order to complete the race, they must run exactly 4 laps. Since Michael is the fastest of the four, he runs 1 1/3 laps. Nate then runs 1/2 lap, followed by Ben running 3/4 lap. How many laps must Andrew run to complete the race? Express your answer as a mixed number.
Answer:
Andrew must run 1 5/12 Laps to complete the race.
Step-by-step explanation:
Total lap run by Michael, Nate, Ben, and Andrew = 4 laps
laps run by Michael = 1 1/3 laps =(3+1)/3 = 4/3 laps
laps run by Nate =1/2 laps
laps run by ben =3/4 laps
Let laps run by Andrew = x
therefore
laps run by Michael + laps run by Nate + laps run by ben + laps run by Andrew = 4 laps
4/3 + 1/2 + 3/4 + x = 4
LCM of 3,2 and 4 is 12
=> (4*4 + 6*1 + 3*3+12x)/12 = 4
=> (16+6+9+12x)/12 = 4
=> 31+12x = 12*4 = 48
=> 12x = 48-31= 17
=> x = 17/12 = 1 5/12
Thus, Andrew must run 1 5/12 Laps to complete the race.

Q1. Helen can collect 240 flowers in 20 minutes. How many flowers can
she collect in 35 minutes?
Answer:
420 flowers
Step-by-step explanation:
20 minutes = 240 flowers
1 minute =240/20 flowers
35 minutes = (240*35)/20 flowers
The answer is 420 flowers.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Helen can collect 240 flowers in 20 minutes.
You need to find the number of flowers she can collect in 35 minutes.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
1: Find the unit rate of Helen collecting flowers. To find the unit rate, just divide 240 by 20, to see how many flowers she can collect per minute.
2: Multiply the number of flowers Helen can collect in 1 minute by 35 (since 1 times 35 is 35).
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
1: 240 divided by 20 is 12. Helen can collect 12 flowers per minute. The unit rate of Helen collecting flowers is 12 flowers per minute.
2: Since Helen can collect 12 flowers per minute, you need to find out how many she can collect in 35 minutes. To get from 1 minute to 35 minutes, you multiply 1 by 35. So you need to multiply 12 by 35 as well. 12 times 35 is 420. So Helen can collect 420 flowers in 35 minutes.

Explain how you can use absolute value to tell wether the sum of two integers is positive or negative
Step-by-step explanation:
Using absolute value to tell wether the sum of two integers is positive or negative.
Suppose we have a positive integer,
x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.
For any integer x, x + (-x) = 0

This year,a farm planted 400,000corn stalks.Last year,the farm planted 275,650cornstalks. How many more cornstalks did the farm plants this year than last year?
Answer:
The farm planted 124,350 more cornstalks
Step-by-step explanation:
Here in this question, we want to know how much more corn stalks did a farm plant this year compared to last year.
Let’s picture it this way;
Possibly due to expansion purposes, the farm planted more cornstalks this year than last year. So to find the difference in the cornstalks planter between the two years, what needs to be done is simply to subtract the number of corn stalks planted last year from the number of corn stalks planted this year.
From the question, the number of cornstalks planted last year was 275,650 while the number of cornstalks planted this year was 400,000; So the difference between the two will be ;
400,000 - 275,650 = 124,350 cornstalks
If (1,-1) is a point on the line 2x-(2a+5)y=5 then find the value of a
Answer:
a = - 1Step-by-step explanation:
Since ( 1 , -1) is a point on the line 2x-(2a+5)y=5 we can substitute it into the equation to find a
We have
2(1) - (-1)(2a + 5) = 5
Multiplying two negatives make a positive
That's
2 + 2a + 5 = 5
2a + 7 = 5
Group like terms
Send the constants to the right side of the equation
That's
2a = 5 - 7
2a = - 2
Divide both sides by 2
That's
[tex] \frac{2a}{2} = \frac{ - 2}{2} [/tex]We have the final answer as
a = - 1Hope this helps you
Why is
[tex] \sqrt{2x} [/tex]
is not a polynomial but
[tex] \sqrt{2}x [/tex]
is a polynomial?
Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers ([tex]0[/tex], [tex]1[/tex], [tex]2[/tex], [tex]3[/tex], [tex]\dots[/tex].)
[tex]\sqrt{2\, x}[/tex] is equal to [tex]\sqrt{2}\, x^{1/2}[/tex]. In this expression, [tex]x[/tex] is the variable. Its exponent is [tex]1/2[/tex], which isn't a natural number. On the other hand, [tex]\sqrt{2}\, x[/tex] is equivalent to [tex]\sqrt{2}\, x^{1}[/tex]. The exponent of variable [tex]x[/tex] is [tex]1[/tex], which is indeed a natural number.[tex]\sqrt{2\, x}[/tex] isn't a polynomial because the exponent of variable [tex]x[/tex] isn't a natural number. On the other hand, [tex]\sqrt{2}\, x[/tex] is indeed a polynomial over the set of real numbers.

the hypothenus of a right angle triangle is 13cm. if one other side of the triangle is 1cm shorter than the hypothenus, calculate the third side of the triangle
Answer:
5 cm.
Step-by-step explanation:
Let the lengths of the other 2 sides be 13-1 = 12 and x cm.
Then by Pythagoras:
13^2 = 12^2 + x^2
x^2 = 13^2 - 12^2
x^2 = 169 - 144 = 25
x = √25
x = 5 cm.
Step-by-step explanation:
Hey, there!!
As per your question,
There is a Right angled triangle, whose hypotenuse is 13 cm, one side is (13-1)=12 cm.
another side = ?
Let ABC be a Right angled triangle, taking angle "theta" as a refrence angle.
Hypotenuse (h)= 13 cm.
base ( b) = x
perpendicular (p)= 12cm.
By Pythagoras relation we get,
[tex]b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]
[tex]b = \sqrt{ {13}^{2} - {12}^{2} } [/tex]
[tex]b = \sqrt{169 - 144} [/tex]
Therefore, base is 5 cm. Or the third side is 5 cm.

Step-by-step explanation:
Coordinates of A,B,C and D are,
A(2, 4), B(4, 4), C(3, 2) and D(1, 2)
Rule for the reflection over a line y = x,
(x, y) → (y, x)

Solve for x: the quantity of x plus 20 over 2 = 3x
Answer:
x = 4
Step-by-step explanation:
For this problem, we simply need to convert the words into the left hand side of the equation and solve for x:
The quantity of implies a grouping
x plus 20 is the quantity
And we want the quantity over 2 all equal to 3x:
( x + 20 ) / 2 = 3x
( x + 20 ) = 6x
20 = 5x
4 = x
And now we can check to see if x is correct by plugging back into the equation:
( x + 20 ) / 2 = 3x
( (4) + 20 ) / 2 ?= 3(4)
( 24 ) / 2 ?= 12
12 == 12
Therefore, we have shown the value of x to be equal to 4.
