Answer: You take the last two digits of the original number and see if they are divisible by 4.

Step-by-step explanation: Take your original number and find the last two digits. If they are divisible by 4, then the original number is divisible by 4.

Answer:

Check the last two digits of the number, if they are divisible by 4 then the entire number is divisible by 4.

Solution:

To check if a number is divisible by 4, there are certain rules.

If a number has more than 2 digits the way to check if it is divisible by 4 is;

Check the tens and ones place, if the last two digits are divisible by 4 then the entire number is divisible by 4.

Also if the tens digit is even then the ones place has to be 0, 4, 8. But if the tens digit is odd then the ones digit must either be 2 or 6.

Why is the rise the value for the numerator and the run the value for the denominator?

Help me please, I need help I don’t understand this problem

The maximum speed of a boat at 30 feet length of water is 0.093 nautical miles/hour or knots.

Step-by-step explanation:

The equation for the maximum speed, s is given by s²= (16/9)x
where, x is the length of the water line in feet.

It is given that, the modeled equation s²= (16/9)x is used to find the maximum speed in knots or nautical miles per hour.

The question is asked to find the maximum speed when the length of the water is 30 feet.

Therefore, to find the maximum speed in 30 feet water, the given modeled equation is used. So, substitute the 30 feet in place of x.

Now, calculating the maximum speed :

s² = (16/9)(30)

s² = 480 / 9

s² = 53.3

Taking square root on both sides,

s = √53.3

s = 7.3

The maximum speed of a boat at 30 feet length of water is 7.3 nautical miles/hour or knots.

If these two shapes are similar, find X

ELEN [110]

Answer:

Step-by-step explanation:

If the shapes are similar we can use the side length proportion to find the value of x:

7/91 = x/52 cross multiply expressions

91x = 364 divide both sides by 91

x = 4

Two planes that are traveling toward each other are 720 miles apart. One plane is traveling 40 miles per hour faster than the ot

natali 33 [55]

Answer:

y = 460 miles per hr

x = 500 miles per hr

Step-by-step explanation:

Let the planes be X any

Let their speeds be xmiles/hr and ymiles/hr respectively

x = y + 40 (assuming X is faster by 40miles/hr)

Distance travelled by X to meet Y = 0.75x

Distance travelled by Y to meet X = 0.75y

0.75x + 0.75y = 720 --------1

Put x = y + 40 in eqn 1

0.75(y+40) + 0.75y = 720

0.75y + 30 + 0.75y= 720

1.5y = 690

y = 460 miles per hr

x = 460 +40

= 500 miles per hr

Help first gets brainly

pentagon [3]

Answer:

1. 100 1. 150 1. 1

2.45 2. 800

Step-by-step explanation:

1. 25% * 400 = 0.25 * 400 = $\frac{1}{4}$ * 400 = 100

2. 50% * 90 = 45

1. 75% * 200 = 0.75 * 200 = 3/4 * 200 = 150

2. 10% * 8000 = 0.1 * 8000 = 800

1. 5% * 20 = 0.05 * 20 = 1
