8 students

Step-by-step explanation:

1. 25×8=200

2. 750÷200=3.75

1. 60×8=480

2. 1680÷480=3.5

1. 4+4=8

Answer:

4 students.

Step-by-step explanation:

Because you times 8 hours by the amount they can do in one hour. And then multiply it untill you get that number of how much they have to do.

Answer:

-8

Step-by-step explanation:

If you do -8 / 1/4 you get -2 as an answer. However if you do 8 / 1/4 you only get 2 as an answer. Thus meaning the answer is 8. Hope this helps.

Answer:

Area of shaded triangle = one - half times 24 square units.

Step-by-step explanation:

The line that is drawn from one corner to the opposite corner is called the diagonal of the rectangle.

The diagonal splits the rectangle into 2 right angled triangle of same measurements.

Therefore,

\(Area \ of\ rectangle\ =\ Area \ of \ triangle + Area \ of \ triangle \\\\Area \ of\ rectangle\ =\ 2 \times\ Area \ of \ triangle\\\\24 = 2 \times Area \ of \ triangle\\\\Area \ of \ triangle = \frac{1}{2} \times 24\)

Answer:

65% of 80 = 52

36% of 125 = 45

82% of 50 = 41

170% of 30 = 51

Step-by-step explanation:

(80/100) x 65 = 52

(125/100) x 36 = 45

(50/100) x 82 = 41

(30/100) x 170 = 51

Answer:

65% of 80 is 52, 36% of 125 is 45, 82% of 50 is 41, and 170% of 30 is 51.

Step-by-step explanation:

     A percent divided by 100 becomes a decimal and "of" means multiplication in mathematics.

65% of 80 = 0.65 * 80 = 52

36% of 125 = 0.36 * 125 = 45

82% of 50 = 0.82 * 50 = 41

170% of 30 = 1.7 * 30 = 51

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

1 and 4

Answer:

A. EAJ and IAH

Step-by-step explanation:

The answer is A. EAJ and IAH because if you notice, angle "EAJ" starts at "E", goes down to "A", and to the right to "J". Now, if you would again notice, angle "IAH" stars at "I", goes up to "A", and to the left to "H".

The definition of a verticle angle are angles opposite each other where two lines cross.

I have attacked an image below of an example of a verticle angle. If you would notice, the image of the vertical angle I attached looks the same as option "A. EAJ and IAH".

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

4.5

-4.6

-4.9 (farthest from zero)

Answer:

The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches.

Step-by-step explanation:

Given that,

The number of ounces of chocolate chips per batch of cookies can be represented with the equation y = 6x, where y represents ounces of chocolate chips and x represents batches of cookies.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,

Given proportionality,

y = 6x

Put y = 45

x = 45 / 6

x = 7.5

Thus, the required number of batches of cookies corresponding to the 45 ounces is 7.5 batches.

Answer:The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.

Number of red marbles pulled = 8

Number of blue marbles pulled = 8

Total marbles pulled = 25

Relative Frequency = Total Frequency / Total number of data values

Relative Frequency of red marble = 8/25

                                                         = 32%

Relative Frequency of blue marble = 8/25

Decimal answer is 13.5

fraction is 13 1/5

Answer: 66/5 or 13 1/5

Step-by-step explanation: The first step in solving this problem is to create two fractions that can be multiplied together. So the first number will be an improper fraction, but that is what you need to do.

4 and 2/5 should be changed by multiplying the denominator (5) times the whole number (4). We get 20. Now we add the numerator (2). The new numerator is then 22. The denominator does not change. 22/5. The 3 can easily be made into a fraction by putting a whole in the denominator. The result is 3/1. Now you can multiply those two fractions together: numerators (22X3) and denominators (5X1).  The result of that is 66/5.  If your supposed to make it a mixed number, divide the top number by the bottom number (66/5) = 13 1/5.

Answer:

\(5x^2 - x - 17\)

Step-by-step explanation:

Distribute the terms inside the first set of parentheses:

\((2x - 7)(x + 3) = 2x^2 + 6x - 7x - 21\)

Combine like terms:

\(= 2x^2 - x - 21\)

Simplify by adding the second part:

\(2x^2 - x - 21 - (-3x^2 - 4)\)

Subtracting a negative is the same as adding the positive equivalent:

\(= 2x^2 - x - 21 + 3x^2 + 4\)

Combine like terms:

\(= 5x^2 - x - 17\)

(2x-7)(x+3)-(-3x^[2] - 4)

====

5x^[2] -x -17

To begin simplifying this expression, we will foil the first half of it:

(2x-7)(x+3)

2x*x + 2x*3 - 7*x - 7*3

2x^[2] + 6x - 7x - 21

With this, we combine like terms:

2x^[2]-x-21

We now have

2x^[2]-x-21-(-3x^[2]-4)

We can now do the binomial distribution in the second half of the expression. Remember, the - sign in front of the parentheses means we are negating everything inside. In other words, we are multiplying -1 by everything inside the parentheses. Following this:

-(-3x^[2]-4) becomes

-1*-3x^[2] + -1*-4 = 3x^[2]+4

We have now simplified the first and second half of our expression, so we have:

2x^[2]-x-21+3x^[2]+4

And combining like terms we get

2x^[2]+3x^[2]-x-21+4 =

5x^[2] -x -17

We can use the quadratic expression to determine if the trinomial can be factored evenly, but it cannot so we have our final simplifed expression!

Answer:

Step-by-step explanation:

probability of an event = # times event has happened / total number of events

probability of someone liking potato chips or pretzels = # of people who like potato chips or pretzels / # total number of people

# of people who like potato chips or pretzels = # people who like potato chips + # people who like pretzels (this works because the two groups don't overlap)

(12+14)/50 = 26/50 = 13/25 = B
