Mathematics
1 answer:
ZanzabumX [31]1 year ago
4 0

Answer:

9/10.

Step-by-step explanation:

3 3/4 ÷ (1 2/3 + 2 1/2)​

= 3 3/4 / ( 5/3 + 5/2)

= 3 3/4 / ( 10/6 + 15/6)

= 3 3/4 / 25/6

= 15/ 4 / 25/6

= 15/4 * 6/25

= 90/100

= 9/10.

If n is a whole number, and 0.01 is between 1/n and 1/n+2, what is the value of n?
OLga [1]

The value of n is 99

Integers are the set of numbers including all natural numbers and 0. They are part of the real numbers that do not include fractions, decimals, or negative numbers. Counting numbers are also considered whole numbers.

Natural numbers together with zero (0) are referred to as whole numbers. We know that natural numbers refer to the set of counting numbers starting from 1, 2, 3, 4 and so on. Simply put, integers are a set of numbers without fractions, decimals, or even negative integers. It is a collection of positive integers and zero. Or we can say that integers are the set of non-negative integers.

Integers are the set of natural numbers togethe with the number 0. In mathematics, the set of integers is given as {0, 1, 2, 3, ...}, denoted by the symbol W.

W = {0, 1, 2, 3, 4, …}

All natural numbers are integers.

All integers are real numbers.

It is given that If n a whole number, and 0.01 is between 1/n and 1/n+2, then we need to find the value of n.

1/n+2 < 0.01 < 1/n

1/n+2 < 1/100 < 1/n

n< 100 < n +2

Put n = 99, then we get

99 < 100 < 101

Hence the value of n is 99.

Select the quadrant in which the terminal side of the angle falls.
Sedbober [7]

Answer:

The answer is below

Step-by-step explanation:

Select the quadrant in which the terminal side of the angle falls.

210° terminates in quadrant

-150° terminates in quadrant

390° terminates in quadrant

Solution:

The x and y axis divides the cartesian plane into four equal parts known as the four quadrants.

Angles between 0° and 90° are in the first quadrant, angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant while angles between 270° and 360° are in the fourth quadrant.

a) Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.

b) -150° = 360 - 150 = 210°. Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.

c) 390° = 390° - 360° = 30°.

Since 30 degrees is between 0° and 90°, hence it terminates in the first quadrant.

(8-2•29) divided by 3
Nesterboy [21]

[(8 - 2 * 29)]/3

Let's solve inside the brackets first.

According to PEMDAS, multiplication gets solved before subtraction so multiply 2 * 29 in the parentheses.

[(8 - 58)]/3

Subtract 58 from 8 in the parentheses.

(-50)/3

Divide -50 by 3.

-16.667 or -16 2/3 is your answer.

Sarah needs to make a cake and some cookies. The cake requires 3/4 cups of sugar and the cookies require 3/5 cups of sugar. If s
Ann [662]

Answer:No, she does not have enough cups of sugar

Step-by-step explanation:

Sarah needs to make a cake and some cookies. The cake requires 3/4 cups of sugar. If she has 15/16 cups of sugar, then the number of cups of sugar that would be left after making the cake would be

15/16 - 3/4 = (15 - 12)/16 = 1/4

If the cookies require 3/5 cups of sugar, then the cups of sugar that she has won't be enough because

1/4 - 3/5 = (5 - 12)/5 = -7/5 cups

It means that she would need more cups of sugar.
