Answer:

I'm not sure what you're trying to ask. Is there a total number of kids?

Answer: There are 120 sixth graders.

Step-by-step explanation.

Just multiply 30 times 4

Answer:

-3

Step-by-step explanation:

The equation would first look like 9/-3

When you are dividing negativ numbers a negative divided by a positive is always a negative so 9/-3 is -3

in³

Using the formula

V=πr2h

Solving forr

r=V

πh=3201

π·5≈14.27522in

Answer: 6

Step-by-step explanation:

Answer:

A. $0.75

Step-by-step explanation:

0.75×2=1.50 (1.50 price of 2 hotdogs)

4-1.50= 2.50 (2.50 is the price of 2 sodas)

1.50 + 2.50= $4

Answer:

Option C

Step-by-step explanation:

To test a graph whether it represents a function or relation we conduct a vertical line graph.

If the vertical line intersect the graph at two different points, graph represents a relation only.

By analyzing the given graph with the vertical line test,

Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),

Given graph represents a relation only.

Option C is the answer.

Answer:

the simplified expression is 14f.

Step-by-step explanation:

Given expression;

6f + 8f

This expression is simplified by adding the two terms together since they are like terms.

6f + 8f  = 14f

Therefore, the simplified expression is 14f.

Answer:

Simplifying

7 + -1(4p + 3) = -3(p + 2) + -1(2P + 3)

Reorder the terms:

7 + -1(3 + 4p) = -3(p + 2) + -1(2P + 3)

7 + (3 * -1 + 4p * -1) = -3(p + 2) + -1(2P + 3)

7 + (-3 + -4p) = -3(p + 2) + -1(2P + 3)

Combine like terms: 7 + -3 = 4

4 + -4p = -3(p + 2) + -1(2P + 3)

Reorder the terms:

4 + -4p = -3(2 + p) + -1(2P + 3)

4 + -4p = (2 * -3 + p * -3) + -1(2P + 3)

4 + -4p = (-6 + -3p) + -1(2P + 3)

Reorder the terms:

4 + -4p = -6 + -3p + -1(3 + 2P)

4 + -4p = -6 + -3p + (3 * -1 + 2P * -1)

4 + -4p = -6 + -3p + (-3 + -2P)

Reorder the terms:

4 + -4p = -6 + -3 + -2P + -3p

Combine like terms: -6 + -3 = -9

4 + -4p = -9 + -2P + -3p

Solving

4 + -4p = -9 + -2P + -3p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '3p' to each side of the equation.

4 + -4p + 3p = -9 + -2P + -3p + 3p

Combine like terms: -4p + 3p = -1p

4 + -1p = -9 + -2P + -3p + 3p

Combine like terms: -3p + 3p = 0

4 + -1p = -9 + -2P + 0

4 + -1p = -9 + -2P

Add '-4' to each side of the equation.

4 + -4 + -1p = -9 + -4 + -2P

Combine like terms: 4 + -4 = 0

0 + -1p = -9 + -4 + -2P

-1p = -9 + -4 + -2P

Combine like terms: -9 + -4 = -13

-1p = -13 + -2P

Divide each side by '-1'.

p = 13 + 2P

Simplifying

p = 13 + 2P

Step-by-step explanation:

We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:

(1) x + y = 39

(2) 4x + 7y = 204

x- number of DVDs; y - number of CDs

solving, x= 23 DVDs

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]

[tex] \frac{10}{x} = \frac{16}{144} [/tex]

Cross multiply

[tex] 10*144 = 16*x [/tex]

[tex] 1440 = 16x [/tex]

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²

Answer:

Answer is 90

Step-by-step explanation:

I had this homework and got it right

Answer:

Step-by-step explanation:

x2 + 5x + 4  (the area of the rectangle)

x + 2   (the length of one side)

(x2 + 5x + 4)/(x + 2)

do a division of this polynomial and you get;    (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method

= [(x+2)(x+3) - 2]/(x + 2)

checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3

Answer:

20:43

Answer:

One, or both the congruent angles measure 30 degrees

Step-by-step explanation:

180 - 120 = 60

60 / 2 = 30

30 + 30 + 120 = 180

Yes

Answer:

30°

Step-by-step explanation:

180-120=60

60/2 = 30

===========================================================

Explanation:

The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.

Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53

Then we move the decimal to the right two spots to get 53%

Roughly 53% of the female students participate in extracurricular activities.

Answer:

y=-3x+13

Step-by-step explanation:

y- 4 = -3(x - 3)​

y-4=-3x+9

y=-3x+13

Answer:

y-4=-3x+9

3x+y-13=0 this is correct answer

I hope it will helps u

As given

x²-3x-10

Now according to the one of the rule of factorization ,

we have to find such two values whose product becomes equal to the

"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".

so such numbers are   -5x and +2x

if we add or multiply them we get the above

as  adding    -5x+2x=-3x  (middle term)

also multiplying   -5x*2x=-10x²  (product of 1st and last term)

so now , we can write as,

x²-3x-10

=x²-5x+2x-10

now making groups of 2 terms,

=(x²-5x)+(2x-10)

now common

=x(x-5)+2(x-5)

now common(x-5)

=(x-5)(x+2)   This is the required factors.....

Answer: x = 10

Step-by-step explanation:

8x = 6x +20

2x = 20

X = 10

Check:

8(10) = 6(10) + 20

80 = 60 + 20

80 = 80

Given:

The perimeter of a rhombus of side d cm  is

[tex]p=4d[/tex]

To find:

The perimeter of a rhombus of  side 3.2 cm.

Find the length of a side of a rhombus  of perimeter 14 cm.

Solution:

Side of a rhombus is 3.2 cm. So, its perimeter is

[tex]p=4(3.2)[/tex]

[tex]p=12.8[/tex]

Therefore, the perimeter of a rhombus of  side 3.2 cm is 12.8 cm.

The perimeter of another rhombus is 14 cm, and we need find its side.

[tex]p=4d[/tex]

[tex]14=4d[/tex]

Divide both sides by 4.

[tex]\dfrac{14}{4}=d[/tex]

[tex]3.5=d[/tex]

Therefore, the length of a side of a rhombus  of perimeter 14 cm is 3.5 cm.

Answer:

Step-by-step explanation:

24/10, 2 4/10 , 12/5

Answer:

p = 3

q = 4

Step-by-step explanation:

p + 2q  = 11          --------------------(I)

       p = 11 - 2q

2p + q = 10         --------------------(II)

Substitute p = 11 -2q in equation (II)

2(11 - 2q) + q =10

2*11 - 2q *2 + q = 10

22 - 4q + q = 10

  22 - 3q    = 10

         -3q   = 10 - 22

        -3q    = -12

              q = -12/-3

 q = 4

Plugin q = 4 in equation (I)

p + 2q = 11

p + 2*4  = 11

p + 8 = 11

      p = 11 - 8

      p = 3
