1) IT TAKES 10 PEOPLE TO PULL A 50 TON BUS.HOW MANY PEOPLE WOULDIT TAKE TO PULL A 100 TON BUS ?

1 answer:

4 0

1) The best thing to do here is to divide the two weights of the buses and fin out what you need to multiply it by.
100/50= 2.
Therefore, you've got to multiply the amount of people by 2.
10*2= 20
Therefore, it takes 20 people to pull a 100 ton bus.

2) Here, you should work out what each one is worth. Half of 40 is 20.
one fourth of 20 is 5. Therefore, half of 40 is larger.

3) The best thing to do is to divide 32 by 8, and then multiply the number of degrees by this.
32/8=4
110*4= 440
Therefore, the ball rotates 440 degrees in 32 seconds.

4) the best thing to do is to find what one part is worth- and to do this, you have to add together the amount of roses and divide this by the total roses.
4+6= 10
50/10= 5
The roses are 6 parts yellow, therefore, 6*5= 30, there are 30 yellow roses.

Hope this helps :)

Charles has six times as many action figures as ben together the action figures total more than 75 how many does each have

seropon [69]

Answer:

We have been given that Charles has six times as many action figures as Ben

Let Ben has x action figures

So according to question Charles will have 6x.

together the action figures total more than 75

$x+6x>75$

$7x>75$

$x>\frac{75}{7}$

So Ben will have more than $\frac{75}{7}$ action pictures.

And $6x>6\frac{75}{7}$

$6x>\frac{450}{7}$

Charles will have more than $\frac{450}{7}$ .

Solve the following system of equations. What is one x-value of a solution?

gulaghasi [49]

Answer:

There is some mistake in the question, because the solutions are x = -1.445 and x = -34.555

Step-by-step explanation:

Given the functions:

f(x) = x² + 4x + 10

g(x) = -32x - 40

we want to find the points at which f(x) = g(x).

x² + 4x + 10 = -32x - 40

x² + 4x + 10 + 32x + 40 = 0

x² + 36x + 50 = 0

Using quadratic formula:

$x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}$

$x = \frac{-36 \pm \sqrt{36^2-4(1)(50)}}{2(1)}$

$x = \frac{-36 \pm 33.11}{2}$

$x_1 = \frac{-36 + 33.11}{2}$

$x_1 = -1.445$

$x_2 = \frac{-36 - 33.11}{2}$

$x_2 = -34.555$

The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.

3241004551 [841]

This is child's play.

So, basically:
Y=Length of foot
X= Length of your forearm.
This is simple. Your equation is Y=0.860x + 3.302
So, if you have a forearm (x) that is 17 inches long, then plug in x as 17. This leaves you to evaluate for Y.
New equation: Y=0.860(17) +3.302
Work it out, you get: Y=14.62 + 3.302
Work that out, you get: Y= 17.922 inches long.
And of course, Y is the foot.

So, your answer: If the forearm is 17 inches long, then the foot is 17.922 inches long. Simple.

So, part 2:
Rate of change. Well, you need slope then, because that's the same thing.
Y=mx+b, Where m=slope
Your answer turns to be 0.860 inches per length of arm, for rate of change.

Skipping the data, as that's only something you'd know.

Yes, it is indeed a function. There can't be any exponents greater than 1 on the placeholder, and it's obviously not a straight line if you plug it in.

So yeah, it's a function.

A soccer ball is kicked from ground level. The function y = -12x (x - 6) shows the height in feet) of the

enot [183]

Answer:

6 seconds

Step-by-step explanation:

Given

y = - 12x(x - 6)

When the ball hits the ground then height of ball is zero

let y = 0 , that is

- 12x(x - 6) = 0

Equate each factor to zero and solve for x

- 12x = 0 ⇒ x = 0 ← when ball is first kicked

x - 6 = 0 ⇒ x = 6 ← when the ball hits the ground.

The ball hits the ground after 6 seconds
