Answer:

33 Students

Step-by-step explanation:

4:7 => 4+7 = 11 < 24 not enough

8:14 => 8+14 = 22 < 24 not enough

16:28 => 16+28 = 44 > 40 alot more

12:21 => 12+21 = 33

24 < 33 < 40

Answer:

Step-by-step explanation:

Let's add the ratios.

The only number that is divisible by 11 and is between 24 and 40 is 33. Let's divide 33 by 11.

Now, let's multiply 3 to each ratio.

Hence, there are 21 girls and 12 boys in the class. The class has a total of 33 students.

Answer:

Step-by-step explanation:

Corresponding sides of congruent figures are congruent. We can use this fact to find x:

  KL = XY

  3x +9 = 129

  3x = 120 . . . . . subtract 9

  x = 40 . . . . divide by 3

__

Similarly, corresponding angles of congruent figures are congruent. This means ...

  ∠J = ∠W

  (2y +2)° = 122°

  y +1 = 61 . . . . . . divide by 2°

  y = 60 . . . . . . subtract 1

Answer:

6 inches

Step-by-step explanation:

let's turn that yard into inches.

12x3=36

so 36/6=6

so each1/6 is equal to 6 inches

5/6 - 4/6=1/6

1/6 = 6 inches

therefore, the adult rough green snake is 6 inches longer than the eastern garter snake

Answer:

g=s/3 or g=s*1/3

Step-by-step explanation:

I'm not 100% sure that this is right but:

s=3g

Divide both sides by 3

g=s/3 or g=s*1/3

Again, not sure if this is right

Answer:

EG = 41

Step-by-step explanation:

since angles E and G are equal, the sides opposite them are equal

5x+23 = 7x+9

23 = 2x+9

14 = 2x

7 = x

EG = 6x-1

substitute 7 for 'x' to get:

EG = 6(7)-1 = 41

The length of the string in cm is; 20 cm

We are told that the string is wound symmetrically around a circular rod.

Now, the circumference of the rod is 4 cm and length is 15 cm.

Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.

Thus, one wound = 4 cm

Since the string makes 5 turns about the rod, then;

Length of string = 5 × 4 = 20 cm

Answer:

RS=188

Step-by-step explanation:

since it is an equilateral triangle the sides are all congruent to each other

therefore:

18x-10=14x+34

18x-14x=34+10

4x=44

x=11

Choose any of the two sides and substitute x for 11 (they will give the same result for reasons stated earlier)

18(11)-10

= 188

Step-by-step explanation:

x = age of Ms T

y = her son's age

x + y = 60

x = 3y

we use the identity of the second equation in the first equation :

3y + y = 60

4y = 60

y = 15

x = 3y = 3×15 = 45

Ms T is 45 years old.

her son is 15 years old.

Answer:

y = m(x-2) + 1

Step-by-step explanation:

y' = 1, x' = 2(From the graph.

...equation of a straight line is y - y' = m(x - x') where m represent the gradient of the slope.

substitute the values of x' and y' into the line equation.

therefore we have, y-1 = m(x - 2)

Now let's solve for y.

y = m(x-2) + 1

that's it.

The value of x is -2

Step-by-step explanation:

Given that

6 (2x + 3) - 3(x - 2) = 6

Expand the bracket                    

6 (2x + 3) - 3(x - 2) = 6

12x + 18 - 3x + 6 = 6

Collect like terms

12x - 3x = 6 - 6 - 18

9x = -18

Divide through by 9

9x / 9 = -18 / 9

x = -2

Therefore, the value of x is -2

Answer:

width = 2 cm

Step-by-step explanation:

are of rectangle is equal to length times width

x is the width, then length is 3x + 4

so x(3x + 4) = 20

3x^2 + 4x = 20

3x^2 + 4x - 20 = 0

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = 3

    b = 4

    c = -20

substitute in the formula

x = [-4 +/-√(4^2 - 4(3)(-20))]/2(3)

x = [-4 +/- √(16 + 240)]/6

x = [-4 +/- 16]/6

x1 = (-4 + 16)/6 = 2

x2 = (-4 - 16)/6 = -20/6

since the width can't be a negative number, x2 is not the right answer

so x = 2
