1. A scale drawing of a school bus has a scale of Vainch to 5 feet. If the length
of the school bus is 4 va inches on the scale drawing, what is the actual
length of the school bus? Explain or show your reasoning.

Uno se pierde, el otro se recicla.

Explicación:

El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.

Step-by-step explanation:

yes

Answer:

(a)

[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]

(b)

i.

[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]

[tex]P(1\ girl) = 0.375[/tex]

ii.

[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]

[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]

iii.

[tex]No\ girl = \{BBB\}[/tex]

[tex]P(No\ girl) = 0.125[/tex]

Step-by-step explanation:

Given

[tex]Children = 3[/tex]

[tex]B = Boys[/tex]

[tex]G = Girls[/tex]

Solving (a): List all possible elements using set-roster notation.

The possible elements are:

[tex]S = \{GGG, GGB, GBG, GBB, BBG, BGB, BGG, BBB\}[/tex]

And the number of elements are:

[tex]n(S) = 8[/tex]

Solving (bi) Exactly 1 girl

From the list of possible elements, we have:

[tex]1\ girl = \{GBB, BBG, BGB\}[/tex]

And the number of the list is;

[tex]n(1\ girl) = 3[/tex]

The probability is calculated as;

[tex]P(1\ girl) = \frac{n(1\ girl)}{n(S)}[/tex]

[tex]P(1\ girl) = \frac{3}{8}[/tex]

[tex]P(1\ girl) = 0.375[/tex]

Solving (bi) At least 2 are girls

From the list of possible elements, we have:

[tex]Atleast\ 2 \ girls = \{GGG, GGB, GBG, BGG\}[/tex]

And the number of the list is;

[tex]n(Atleast\ 2 \ girls) = 4[/tex]

The probability is calculated as;

[tex]P(Atleast\ 2 \ girls) = \frac{n(Atleast\ 2 \ girls)}{n(S)}[/tex]

[tex]P(Atleast\ 2 \ girls) = \frac{4}{8}[/tex]

[tex]P(Atleast\ 2 \ girls) = 0.5[/tex]

Solving (biii) No girl

From the list of possible elements, we have:

[tex]No\ girl = \{BBB\}[/tex]

And the number of the list is;

[tex]n(No\ girl) = 1[/tex]

The probability is calculated as;

[tex]P(No\ girl) = \frac{n(No\ girl)}{n(S)}[/tex]

[tex]P(No\ girl) = \frac{1}{8}[/tex]

[tex]P(No\ girl) = 0.125[/tex]

Answer:

-3.5 meters per second

Step-by-step explanation:

got it right on iready lol

Answer:

-3.5 meters

Step-by-step explanation:

Answer:

A = 4.5

Step-by-step explanation:

Area of a triangle:

A = 1/2bh

Given:

b = 3

h = 3

Work:

A = 1/2bh

A = 1/2(3)(3)

A = 1.5(3)

A = 4.5

Answer: The slope is 0.

The slope is 0 because for something to have a slope, it either has to be going upward or downwards.

Answer:

8/12

Step-by-step explanation:

if you have 2 dice and roll them t the same time you have 11 possible outcomes. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. If you roll something higher then a 4 then you get left with 5, 6, 7, 8, 9, 10, 11, 12. If you count them there is 8 different outcomes you can get out of the 2 dice since the highest you can roll is a 12.

Answer:

Sale price= $25.5

Step-by-step explanation:

Giving the following information:

The original price was $29.99, but the ball was on sale for 15% off.

To calculate the sales price, we need to use the following formula:

Sale price= original price* (1 - sales discount)

Sale price= 29.99*(1 - 0.15)

Sale price= $25.5

(I think that says 51...)

Basically all you do is multiply 51 by 4

 51

x  4

104

The answer (if those numbers are correct) is 104.

Answer:

D. 800 m

Step-by-step explanation:

Volume of a cylinder is πr²h

Here, r=10 h=8

so the volume is

=π x 10² x8

=π x 100 x 8

=800m

The answer is 800m

Answer:

[tex]D[/tex]

Step-by-step explanation:

[tex]Volume[/tex]  [tex]of[/tex] [tex]cylinder[/tex] ≈ [tex]\pi[/tex] [tex]radius^{2}[/tex] × [tex]height[/tex]

[tex]Volume[/tex]  ≈ [tex]\pi[/tex] × [tex]10^{2}[/tex] × 8 [tex]800\pi[/tex]

Answer:

the answer to this question is 4.4

Answer:

4.4

Step-by-step explanation:

We will use Pythagorean Theorem to find the remaining side.

Since the hypothenuse (10) is already found, we will do this a little more unconventionally.

9²+x²=10²

x Represents the missing side.

81+x²+100

x²=19

x≈ 4.4

y=9,49

Step-by-step explanation:

y=3,17×+6,32

y=9,49×

Answer:

q = - 13

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 6

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)

m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then

- 7 - q = 6 ( add 7 to both sides )

- q = 13 ( multiply both sides by - 1 )

q = - 13

Answer:

q = -13?

Step-by-step explanation:

the equation is y = mx + c

m is the gradient

c is the y-intercept

where the line crosses the y axis

If 6 is the gradient then the equation is

y = 6x + c

Find c by using the coordinates given:

-7 = ( 6× 0) +c

-7 = 0 + c

c = -7

the equation is y = 6x -7

Substitute the other coordinates to find q:

y or q = (6 ×-1) - 7

q = -6 -7

q = -13

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let “ab” represent the digits of the number.

a ≠ 0

Value of the number = 10a+b

a+b + ab = 10a + b

a + ab = 10a

ab = 9a

b = 9

“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99

Answer: 49

Step-by-step explanation:

4x9=36

4+9=13

36+13=49
