Answer:

its simple greatest number less that 400 is 399

Answer:

388

Step-by-step explanation:

Definition from Wikipedia

In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4  (https://en.wikipedia.org/wiki/Greatest_common_divisor)

Methodology to find greatest common denominator(factor) for 2 numbers

Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6

Answer:

26% of the jelly beans are yellow

Step-by-step explanation:

To find this we add up all the jelly beans which is 200 jelly beans

Then we divide it by the number of yellow jelly beans which is 52/200

which then equals .26. In a percentage that is 26%

Answer:

(3/2 m)^2 -(5n)^2^

Step-by-step explanation:

Answer: 9m^2 / 4  -  25n^2

Step-by-step explanation:

Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

15%

Step-by-step explanation:

179.3 - 153.02 = 26.28

26.28/179.3 = 0.14656999442 or approximately 0.15 (rounded to the nearest hundreth)

Answer:

14.65%

Step-by-step explanation:

Original SP = $179.3

Sale price after discount = $153.02

Decrease % = \(\frac{(SP - Saling price)}{OriginialSP}\) × 100

= \(\frac{26.28}{179.3}\) × 100

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.

504 divided by 9 equals 55 remainder 4, or 55.4 in decimal form.

Using the procedures below, you can divide 504 by 9 to reach the answer:

You may find the quotient for the hundreds place by dividing the dividend's initial digit (504) by the divisor (9).

Given that 5 is less than 9, 5 9 equals 0.

Add 0 as the following digit from the dividend to the quotient that was determined in the previous step.

The current ratio changes to 05.

You get the quotient for the tens place by dividing the new dividend (50) by the divisor (9): 50 ÷ 9 = 5.

Add the new (5) quotient to the original (5) quotient.

The existing quotient changes to 055.

Bring the dividend's final digit, which is 4, down.

You get the quotient for the units place by dividing the new dividend (44) by the divisor (9). 44 9 = 4; the remaining 8 is.

Add the new quotient (4) to the old one (1). 0554 is the final quotient.

Hence 504 divided by 9 equals 55 remainder 4, or 55.4 in decimal form.

Answer:

$16.75

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 67 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 67 is 100%, so we can write it down as 67=100%.

4. We know, that x is 25% of the output value, so we can write it down as x=25%.

5. Now we have two simple equations:

1) 67=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

67/x=100%/25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 67

67/x=100/25

(67/x)*x=(100/25)*x       - we multiply both sides of the equation by x

67=4*x       - we divide both sides of the equation by (4) to get x

67/4=x

16.75=x

x=16.75

now we have:

25% of 67=16.75

Step-by-step explanation:

This is proportional relationship because y grows by 1.5 times each time.

Assuming there is the same amount of cups of milk per serving.

Answer:

\(5~1/4\)

Step-by-step explanation:

When we increase from \(8\) servings to \(24\) servings, we triple the amount of servings needed, and hence we triple the amount of ingredients needed.

So, the amount of cups of milk needed is \(3(1+3/4)=3+9/4=3+2~1/4=5~1/4\).

So, the answer is \(\boxed{5~1/4}\) and we're done!

The number of cups of milk needed for the recipe is 5 1/4 cups.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s. If both these ratios are proportional, then we can write it as  p : q = r : s.

Given that,

A recipe calls for 1 3/4 cups of milk for 8 servings.

We have to find the number of cups of milk needed for 24 servings.

The ratio of the number of cups of milk to the number of servings will be equal.

Let x be the number of cups of milk needed for 24 servings.

1 3/4 cups = 7/4 cups

Using proportion,

7/4 / 8 = x / 24

8x = 7/4 × 24

8x = 42

x = 42 / 8

  = 21 / 4

  = 5 1/4 cups.

Hence the number of cups needed for 24 servings is 5 1/4 cups.
