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.

Answer: D

Step-by-step explanation:

Answer:

x = 3z(y - 2)

Step-by-step explanation:

Given

[tex]\frac{x}{3z}[/tex] = y - 2 ( multiply both sides by 3z to clear the fraction )

x = 3z(y - 2)

Answer:

x - 13 = 13 - x

Step-by-step explanation:

The commutative property of addition is a+b=b+a

The third equation is the only one not following the rule. It states that a-b=b-a, whoich is not true.

For exaple, 2-1 is not equal to 1-2.

Answer:

Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.

Answer:

A = 16π cm²

Step-by-step explanation:

We require to find the radius r

Given circumference C = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4 , then

A = πr² = π × 4² = 16π cm²

Answer:

A = 16π cm²

22

Step-by-step explanation:

11% of 196 = 21.56

Divide by 10 and divide by 100. Add them together

You must round this up because you cant really have .56 of a person.

Answer:

32 Square centimeters

Step-by-step explanation:

You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.

Hope my answer helped!

Answer:

5x^2-4+4(x^2)-6x

Step-by-step explanation:

first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)

then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer

Answer: (0,−10),(1,−7),(2,−4)

Answer: 2 1/2kg

Step-by-step explanation:

Weight of plant food bought = 4 1/2kg

Amount used on strawberry plant = 1 2/3kg

Amount used on tomato plant = 1/4kg

Therefore, the amount used will be:

= 1 2/3 + 1/4

= 1 8/12 + 3/12

= 1 11/12kg

We then subtract the value gotten from the amount bought. This will be:

= 4 1/2 - 1 11/12

= 4 6/12 - 1 11/12

= 2 6/12

= 2 1/2kg

No

Answer:

  y = -3/2x +11

Step-by-step explanation:

The slope of the parallel line is the same as the slope of the given line, so ...

  m = -3/2

The y-intercept of the parallel line can be found from ...

  b = y -mx

  b = 5 -(-3/2)(4) = 11

So, the desired equation is ...

  y = mx +b

  y = -3/2x + 11

_____

Additional comment

Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.

  y -5 = -3/2(x -4)

Actually Welcome to the Concept of the Simple maths.

Here,

61 = r/3 - 7

hence, r/3 = 61+7

===> r/3 = 68

==> r = 68*3

====> r = 204

Option c.) is correct.

Answer: there were 12 chocolates in each box. (Originally, before any got eaten)

Step-by-step explanation: let x represent the total amount of chocolates in each box.

8x - 3(8) = 72

8x - 24 = 72 add 24 to both sides

8x = 96 divide both sides by 8

X = 12

Answer:

That means you had 48 chocolates in each box

Step-by-step explanation:

Since you eat 3 chocolates from all 8 boxes, you do this:

8 x 3 which = 24

Now since you have 72 chocolates left you do this:

72 - 24 which = 48

So, therefore, there were originally 48 chocolates in each box

(Don't eat so much chocolate lol you could get sick)

Answer:

Two times the sum of a number and nine.

Step-by-step explanation:

Answer:

two times the sum of n plus nine.

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.

Answer:

Option D

Step-by-step explanation:

→ Find the gradient of the parallel line

[tex]y=-\frac{2}{3} x+c[/tex]

→ Substitute in the coordinates as x and y values to find c

[tex]5=-\frac{2}{3} *-4+c[/tex]

→ Simplify

[tex]5=\frac{8}{3} +c[/tex]

→ Minus  [tex]\frac{8}{3}[/tex]  from both sides to find c

[tex]c = \frac{7}{3}[/tex]

→ Expand out all options and then see which one contains all the numbers above

Option D
