One-eight of class graduated with a A average, 1/2 got a B, and the rest of the class had a C average. In a class of 800, how many had C average?

Answer:

5 and she will have 4/5 remaining.

Step-by-step explanation:

If you multiply the 5 slices per pizza by 4 pizza's you would be able to feed 20 students. Since her goal is to make sure EACH student gets 1/5 of a pizza she would need to order another one. So she needs to purchase 5 pizzas and would have 4 slices remaining.

(She could always eat those by herself or give them to me lol)

Hope that helps and have a great day!

Answer:

Mrs. Johnson need to order 5 pizzas.

Step-by-step explanation:

1. If you do 5, 10, 15, 20 that’s four

2. it’s not fair to leave one kid out so she needs to order 5 pizzas

The value of x is 0.918 for the equation 3.2x - 1.7x + 5.5 = 10.

To determine this equation 3.2x - 1.7x + 5.5 = 10,

3.2x - 1.7x + 5.5 = 10

Subtract 10 on both side,

3.2x - 1.7x + 5.5 - 10 = 10 - 10

3.2x - 1.7x + 4.5 = 0

Subtract 4.5 on both side,

3.2x - 1.7x = -4.5.

4.9x = -4.5

x = 0.918.

Therefore, the value of x is 0.918.

Answer:

67100

1300

Step-by-step explanation:

You are rounding to the nearest hundreds place value (will be underlined and bolded). Note the number directly next to the place value (tens place value). If it is the digit 5 or greater, round up. If 4 or less, round down:

67103:

You are rounding to the hundreds place value. The tens place value is a 0. Because 0 is less than 5, round down.

67103 rounded to the nearest hundred is 67100.

1273:

You are rounding to the nearest hundreds place value. The tens place value is a 7. Because 7 is greater than 5, round up.

1273 rounded to the nearest hundred is 1300.

Step-by-step explanation:

x + 9 = 4(x-1)²

x + 9 = 4(x² - 2x + 1)                  Multiply (x - 1) times (x - 1)

x + 9 = 4x² - 8x + 4                  

4x² - 9x - 5 = 0                          Subtract x + 9 from both sides

Answer:

15

Step-by-step explanation:

f(x)=6x-9

so nw x value give 4,

substitute x value with 4

f(4)=6(4)-9

=19

A function assigns the values. The value of the f(4) will be equal to 15.

A function assigns the value of each element of one set to the other specific element of another set.

For the given function f(x)=6x-9, therefore, the value of f(4) can be written as,

f(x) = 6x - 9

f(4) = 6(4) - 9

f(4) = 24 - 9 = 15

Hence, the value of the f(4) will be equal to 15.

Answer:

39/4

Step-by-step explanation:

Because I multiplied 4 x 9 + 3

9 3/4 may be expressed as an improper fraction as 39/4 or 9.75.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.

9¾ is a mixed fraction. 9 is the whole number whereas ¾ is the fractional part. 9¾ is also 9+¾.

Fractions that have a numerator greater than a denominator, such as 8/7 or 123/112, are considered improper fractions.

Thus, to convert 9 3/4 into an improper fraction, multiply the whole number component—in this case, 9, by the denominator (4 in this case). The multiple of 9 and 4 you just discovered is added to the numerator (3), which is then used as the numerator. The numerator (four) stays the same.

Therefore,  9 3/4  can be written as 39/4 or 9.75 in the terms of the improper fraction.

Answer:

[tex]\displaystyle \frac{199}{18}[/tex]

Step-by-step explanation:

Fraction Operations

Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.

[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]

[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]

Now for the sum of the last two fractions:

[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]

Make both denominators equal by multiplying by 2 both parts of the first fraction:

[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]

[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]

Now multiply by 7/9:

[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]

Step-by-step explanation:

The number 531.775197122 is rounded to the nearest ten thousandth place by 531.7752

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Given data ,

Let the number be = A

Let the rounded number be = B

The value of A is given by

A = 531.775197122

Now , the number A can be rounded of to the nearest ten thousandth place by rounding to the nearest 0.0001 or the Ten Thousandths Place

So , the number will be

The 1 in the ten thousandths place rounds up to 2 because the digit to the right in the hundred thousandths place is 9

When the digit to the right is 5 or greater we round away from 0

Therefore , the number 531.775197122 is rounded to 531.7752

Therefore , the value of B is 531.7752 after rounding up

Hence , The number 531.775197122 is rounded to the nearest ten thousandth place by 531.7752
