Answer:

2^n pieces

80 / (2^n) in²

Step-by-step explanation:

If she cuts the paper in half 1 time, she will have 2 pieces.

If she cuts the paper in half 2 times, she will have 4 pieces.

If she cuts the paper in half 3 times, she will have 8 pieces.

So the pattern is 2^n.

The original area is 80 in².  Divided by 2^n pieces means each piece has an area of 80 / (2^n) in².

Answer:

[tex]3 \frac{3}{4} \times 3 \frac{1}{3} = \frac{15}{4} \times \frac{10}{3} = \frac{25}{2} = 12 \frac{1}{2} [/tex]

The area of this room is 12 1/2 yd².

The area of the rectangular room is (12.5) square yards, calculated by multiplying length and width.

To find the area of a rectangular room, you multiply its length by its width. Given that the length is [tex]\(3 \frac{3}{4}\)[/tex] yards and the width is  [tex]\(3 \frac{1}{3}\)[/tex] yards, you can calculate:

[tex]\[ \text{Area} = \text{Length} \times \text{Width} \][/tex]

First, let's convert the mixed numbers to improper fractions:

[tex]\[ 3 \frac{3}{4} = \frac{4 \times 3 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4} \text{ yards} \]\[ 3 \frac{1}{3} = \frac{3 \times 3 + 1}{3} = \frac{9 + 1}{3} = \frac{10}{3} \text{ yards} \][/tex]

Now, plug these values into the formula:

[tex]\[ \text{Area} = \frac{15}{4} \times \frac{10}{3} \]\[ \text{Area} = \frac{15 \times 10}{4 \times 3} \]\[ \text{Area} = \frac{150}{12} \]\[ \text{Area} = 12.5 \text{ square yards} \][/tex]

So, the area of the rectangular room is [tex]\(12.5 \, \text{square yards}\).[/tex]

The easiest thing to do here is:

4x + 2 = -2 and 4x + 2 = 26

Just know whaever you get for x is greater or less than the actual answer.

4x + 2 = -2

      - 2  - 2

 4x = -4

 [tex]\frac{4x}{4} = \frac{-4}{4}[/tex]

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.

4x + 2 = 26

     - 2    - 2

  4x = 24

  [tex]\frac{4x}{4} = \frac{24}{4}[/tex]

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6

Answer:

-1 > x OR 6 < x

Step-by-step explanation:

4x + 2 > 26

Final answer:

The negative square root of two, −√2, falls between the consecutive integers -2 and -1 on the number line.

Explanation:

The student is asking about the position of the square root of a negative number on the number line, specifically −√2 (negative square root of two). To answer this, we first need to understand that the square root of a positive number is a number that, when squared, gives the positive number in question. For √2, we know that it falls between 1 and 2 because 1 squared is 1 and 2 squared is 4, and 2 lies between these two values.

Since the student is asking for negative √2, we simply reflect the position of √2 across the origin (zero) on the number line to find where −√2 lies. Hence, −√2 will fall between the integers -2 and -1. If we were estimating, we might say it is just a bit closer to -2 than -1, because √2 is approximately 1.414.

Answer:

32+q

Step-by-step explanation:

The complete question is

Jake has 32 quarters on his desk, molly has q quarters in her purse.  

Which algebraic expression represents the total number of quarters that Jake and Molly have?  

we know that

To find out the total number of quarters that Jake  and Molly have, sum the amount of quarters that Jake has plus the amount of quarters that Molly has

Let

x ----> the amount of quarters that Jake has

y ----> he amount of quarters that Molly has

so

x+y

we have

[tex]x=32\ quarters\\y=q\ quarters[/tex]

substitute

32+q

Answer:

63/h - 3.14

Step-by-step explanation:

Quotient means divide.

So the answer to the division is a quotient. 63/h is the quotient of the division.

Less means subtract so the subtraction that is taking place is

63/h - 3.14 and that's your answer.

Often with these questions, you start backwards as in this question.

Answer:

1,888 bags.

Step-by-step explanation:

Let x represent the the weight of container of peppercorns.

We have been given that the container of oregano is 17 pounds heavier than a container of peppercorns. So the weight of container of oregano would be [tex]x+17[/tex].

We are also told that the total weight of both containers is 253 pounds. We can represent this information in an equation as:

[tex]x+x+17=253[/tex]

Let us solve for x.

[tex]2x+17=253[/tex]

[tex]2x+17-17=253-17[/tex]

[tex]2x=236[/tex]

[tex]\frac{2x}{2}=\frac{236}{2}[/tex]

[tex]x=118[/tex]

Therefore, the weight of peppercorns is 118 pounds.

Now, we will convert 118 pounds to ounces.

1 pound equals 16 ounces.

118 pounds = 118*16 ounces = 1,888 ounces

Since the peppercorns will be sold in one-ounce bags, therefore, 1,888 bags of peppercorns can be made.

Answer:

Step-by-step explanation:

Answer:

-4 and 6

Step-by-step explanation:

sum means +

-4+6=2

difference means -4-6=10

The sum of two integers is 2 and their difference is 10 then the two integers will be -4 and 6 and this can be determined by using the arithmetic operations.

Given :

Let the two integers be 'a' and 'b'. Then the sum of the two integers will be:

a + b = 2   ---- (1)

The difference between the two integers will be:

a - b = 10  ----- (2)

Now, solve the equation (1) for 'a'.

a = 2 - b --- (3)

Now, put the value of 'a' in equation (2).

2 - b - b = 10

2 - 2b = 10

2b = -8

b = -4

Put the value of 'b' in equation (3).

a = 2 - (-4)

a = 2 + 4

a = 6

Therefore, the correct option is D) -4 and 6.

Brady

  Number of Gold medals won by USA are 9 and gold medals won by France are 2.

   Let the gold medals won by USA = x

And the gold medals won by France = y

It's given in the question "gold medals won by USA are 1 more than 4 times the number of gold medals won by France"

Therefore, equation for this situation will be,

x = 4y + 1 --------(1)

Second statement of the question states "USA won 7 gold medals more than France"

Therefore, equation will be,

x = y + 7 -------(2)

By substituting the value of 'x' in equation (1) from equation (2),

y + 7 = 4y + 1

4y - y = 7 - 1

3y = 6

y = 2

By substituting the value of 'y' in equation (1),

x = 4(2) + 1

x = 9

      Therefore, USA won 9 gold and France won 2 gold medals in the Winter Olympic Games.

Answer:

(1).(C) Commutative property.

(4).(D) 3

(3).(D)  75

Step-by-step explanation:

(1) Commutative property of addition states that if two number p and q are real. Then, it doesn't matter in which order the numbers are added it will provide the same result. i.e.

p + q = q + p

Therefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.

(2) - (q+14) = (-3) + (-14)

[tex]\Rightarrow -q - 14=-3 -14[/tex]

[tex]\Rightarrow-q= -17 +14[/tex]

[tex]\Rightarrow-q=-3[/tex]

[tex]\Rightarrow q=3[/tex]

Explanation:

Since both numbers have 15,006 before the decimal we only need to see which number has a bigger decimal.

0.099 < 0.101

0.101 - 0.099 = 0.002

So, 15,006.101 is 0.002 bigger than 15,006.099!
