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 :)

Crank

Answer: x ≥ 7

Step-by-step explanation:

You have to square both sides of the equation. You can manipulate an equation or function any way imaginable as long as it is done equally and helps the problem become easier. If we square this, the radical will cancel and we will get two trinomials equal to each other.

$x^2-14x+49=(x-7)^2\\x^2-14x+49=x^2-14x+49$

We can see the two expressions are exactly equal to each other. All real numbers are solutions, besides a few. These few are when the radical is equal to a negative number. So lets set up an inequality stating that the radical must be greater than or equal to 0.

$x^2-14x+49\geq 0\\(x-7)^2 \geq 0\\x \geq 7$
