The ratio of boys to girls in a class is 3:5. There are 40 students in the class. How many more girls than boys are there?
Answer:
I think it is 8 (not %100 sure)
Step-by-step explanation:
what I did was I divided 40 by 5 which gave me 8
I hope this helps;) sorry if it dosen't
Answer:
The Answer Is 10
Step-by-step explanation:
The Total Strength = 40 Students
The Ratio Of Boys To Girls = 3:5
So, 3 + 5 = 8
Then, Divide 8/40 So That U Get The Number Then Multiply It With The Ratio.
•8/40 = 5
•5 × 3 = Boys Strength Which Is = 15
•5 × 5 = Girls Strength Which Is = 25
So, There Are 10 Girls More Than Boys.
Hope It Helps U.

Ali, Carrie and Bryan received a sum of money. Bryan's money was 3/5 as much as Ali's money. The ratio of Ali's money to Carrie's money was 4:1. Ali had $160 more than Bryan. How much was the sum of money.
Answer:
The sum of money received by Ali, Carrie and Bryan is $ 740.
Step-by-step explanation:
At first we translate mathematically each sentence:
(i) Ali, Carrie and Bryan received a sum of money.
[tex]a[/tex] - Ali's money.
[tex]b[/tex] - Bryan's money.
[tex]c[/tex] - Carrie's money.
(ii) Bryan's money was [tex]\frac{3}{5}[/tex] of Ali's money.
[tex]b = \frac{3}{5}\cdot a[/tex] (1)
(iii) The ratio of Ali's money to Carrie's money was 4 : 1.
[tex]\frac{a}{c} = 4[/tex] (2)
(iv) Ali had $ 160 more than Bryan.
[tex]a = b + 160[/tex] (3)
After some algebraic handling, we have the following system of linear equations:
[tex]3\cdot a - 5 \cdot b = 0[/tex] (1b)
[tex]a - 4\cdot c = 0[/tex] (2b)
[tex]a - b = 160[/tex] (3b)
The solution of the system is: [tex]a = 400[/tex], [tex]b = 240[/tex], [tex]c = 100[/tex]
The sum of money is:
[tex]s = a + b + c[/tex]
[tex]s = 740[/tex]
The sum of money received by Ali, Carrie and Bryan is $ 740.

Answer:
For an object of mass M and velocity V, the kinetic energy is written as:
K = (M/2)*V^2
And also remember that:
1 J = 1 kg*m/s
a) we know that:
Mass = M = 0.7 kg
Velocity = V = 60 m/s
Then the kinetic energy is:
K = (0.7kg/2)*(60m/s)^2 = 1,260 J
b) We know that in a closed system, the energy is conserved.
This means that if we hit an object with an energy E, the maximum energy that we can give to that object is E.
Then if we have a bat of mass M = 2kg, and velocity V = 30m/s
The kinetic energy of the bat (before hitting the ball) is:
K = (2kg/2)*(30m/s)^2 = 900 J
Obviously, this will never happen, because after we hit the ball the bat keeps moving for a bit, meaning that it still has some kinetic energy and it did not transfer all of the kinetic energy to the ball. But we can not have a more precise estimation, because we do not know the mass of the ball and a lot of other needed information, so we can conclude that, the theoretical maximum energy that could be given to the ball, is 900 J.
c) Here we have:
Mass = M = 1950 kg
Velocity = V = 10 m/s
then the energy is:
K = (1950kg/2)*(10 m/s)^2 = 97,500 J.
d) Notice that in the equation of the kinetic energy we have the velocity squared, which means that the contribution of the velocity is larger than the contribution of the mass.
Then the option with the largest velocity most likely would have the largest kinetic energy, then the correct option is the second counting from the top, with a kinetic energy equal to:
K = (0.25 kg/2)*(50m/s)^2 = 312.5 J.
Question 5
Two angles are complementary. If one of the angles measures 57 degrees,
how much does the other angle measure?
Answer:
33 degrees
Step-by-step explanation:
Complementary angles are 90 degrees when added.
So to find the measure of the other angle just subtract 57 from 90.
90 - 57 = 33

Answer:
126 minutes, or 2.1 hours.
Step-by-step explanation:
Change 6 hours to minutes. (6x60=360)
Find 1% of 360 (360x0.01=3.6)
Multiply 3.6 to 20 (cleaning) and then multiply 3.6 to 15 (video games)
Then, add them, which you should get the answer of 126.
The zoom feature on a camera
lens allows you dilate what
appears on the display. When
you change from 100% to
500%, the new image on your
screen is an enlargement of the
previous image with a scale
factor of 5. If the new image is
47.5 millimeters wide, what was
the width of the previous
image?
Select one:
a. 9.5 millimeters
O b. 23.75 millimeters
O c. 118.75 millimeters
O d. 237.5 millimeters
Answer:
23.75
its 23.75 you need fo divide it..stn loona
Answer:
9.5 milimeters
Step-by-step explanation:
100/500 = x/47.5
x = 9.5
(or just divide 47.5 by 5 because the scale factor was given)

Please help! Simply the polonomials!
Answer:
1) 11x^3 - 6x - 3
2) 3x^3 + 4x^2 - 2x - 1
3) 9x^2 - 4
4) -4x^4 + 2x^3 - x^2
5) x^3 - 38x - 12
Step-by-step explanation:
1) (3x^4 + 5x^3 - 7x + 2) - (3x^4 - 6x^3 - x + 5)
Step 1: 3x^4 + 5x^3 - 7x + 2 - 3x^4 + 6x^3 + x - 5 (multiply the terms in the parenthesis by the constants, which are 1 and -1)
Step 2: 3x^4 - 3x^4 + 5x^3 + 6x^3 - 7x + x + 2 - 5 (reorganize the polynomial by exponential values (ex: x^4 before x^3 before x^1))
Step 3: 11x^3 - 6x - 3 (add like terms)
2) (3x^3 + 8x - 3) + (4x^2 - 10x + 2)
Step 1: 3x^3 + 8x - 3 + 4x^2 - 10x + 2 (multiply the terms in the parenthesis by the constants)
Step 2: 3x^3 + 4x^2 + 8x - 10x - 3 + 2 (reorganize the polynomial)
Step 3: 3x^3 + 4x^2 - 2x - 1 (add like terms)
3) (3x + 2)(3x - 2)
Step 1: 9x^2 - 6x + 6x - 4 (Use FOIL to multiply binomials, or multiply the first terms, outside terms, inside terms, then last terms)
Step 2: 9x^2 - 4 (add like terms)
4) -x^2(4x^2 - 2x + 1)
Step 1: (-x^2*4x^2) + (-x^2*(-2x)) + (-x^2*1) (multiply -x^2 by each term)
Step 2: -4x^4 + 2x^3 - x^2 (simplify; remember x^2 is the same as -1*x^2)
5) (x + 6)(x^2 - 6x - 2)
Step 1: ((x*x^2) + (x*(-6x)) + (x*(-2))) + ((6*x^2) + (6*(-6x)) + (6*(-2))) (multiply the first term in the binomial by each term in the trinomial, and do the same with the second term)
Step 2: x^3 - 6x^2 + 6x^2 - 2x - 36x - 12 (simplify and reorganize)
Step 3: x^3 - 38x - 12 (add like terms again)
