Answer:

The fraction 22/7 is sometimes used as an estimate of is "pi."

Yes, it is a repeating fraction.

Step-by-step explanation:

22 divided by 7 is 3.142857142857143... going on into infinity. It is an estimate of pi, and does repeat every 6 decimal numbers.

Answer:

60

Step-by-step explanation:

The 6 in 126 743 has a place value of 6000.

A number that is one-hundredth the value of 6000 is

6000/100 = 60

Any number that has a 6 in the tens place has a 6 with a place value of 60.

Two examples are 60 and 124 763.

Answer:

96 sqrt(210)

Step-by-step explanation:

6√3 • 8√14 • √10 • √2

We multiply what is outside the square roots with what is outside the square roots  and what is inside the square roots with what is inside the square roots

6*8 = 48

3*14*10*2 = 840

6√3 • 8√14 • √10 • √2

48 sqrt(840)

48 sqrt( 4*210)

sqrt(a*b) = sqrt(a) sqrt(b)

48 sqrt(4) sqrt(210)

48 *2 sqrt(210)

96 sqrt(210)

210 is 3*7 *5*2  which are all primes, so we cannot simplify the sqrt (210)

Answer:

7.5 litres.

Step-by-step explanation:

Volume of water lost in 1 month = 2.5 * 10^-4 * 3 * 10^5

= 2.5 * 3 * 10^(-4+5)

= 7.5 * 10^1

= 7.5 litres (answer)

Answer: its correct because as x increases by 2 the function increases by two at the same time causing answer b to correctly describe what is happening.

Choice B is correct because the function creates a steep slope that increases rapidly (the majority of the other answers are saying that the slope of the function increases slowly, which is not true). Here is an image of the graph of the function:

Answer:

x = 10

Step-by-step explanation:

An equilateral triangle has 3 congruent sides.

Let each side have length s.

P = 60 cm

P = 3s

3s = 60 cm

s = 20 cm

Each side has length 20 cm.

Draw an equilateral triangle with a horizontal side on the bottom. From the top vertex, drop a vertical segment to the horizontal side. This segment is the altitude. The altitude is the perpendicular bisector of the horizontal side of the triangle. Now you have two small congruent triangles, one on each side. One angle at the horizontal side is 60 degrees. The other is 90 degrees. The top angle is 30 degrees. Half of the bottom side of the original equilateral triangle has length 10 cm. The hypotenuse is 20 cm. The altitude is the third side.

10^2 + 20^2 = altitude^2

altitude^2 = 20^2 - 10^2

altitude^2 = 400 - 100

altitude^2 = 300

altitude^2 = 100 * 3

altitude = sqrt(100) * sqrt(3)

altitude = 10sqrt(3)

altitude = x * sqrt(3)

x = 10

Answer:

Federico

Step-by-step explanation:

11/10 is a mixed number, that means it is larger than the whole, which in this case is the money for the school trip, since the numerator is larger than the denominator, and Luis and Marisa both have numerators smaller than the denominator, that makes 11/10 the largest.

Answer:

360 screws

Step-by-step explanation:

First we need to determine how many screws she needs for the 2 decks

We will determine the number of screws for 1 deck

1 deck uses 25 pieces of wood

25 pieces of wood * 8 screws/ piece of wood = 200

200 screws per deck

She is building 2 decks

2 * 200 = 400

400 screws for the 2 decks

She has 40 screws

400 screws she needs - 40 screws she has = 360 screws she still needs

Answer:

81/16

Step-by-step explanation:

We have [(3^2 * 5^0) / 4]^2

= [ ( 9 * 1) / 4]^2

= (9/4)^2

= 81/16

Answer:

81/16

Step-by-step explanation:

3 to the power of 2 multiplied by 5 to the power of 0 whole over 4, the whole squared

[(3^2 * 5^0)/4]^2

According to PEMDAS, we work the inside parentheses first

3^2 * 5^0

3^2 = 9

5^0 = 1

9*1 =9

[(3^2 * 5^0)/4]^2

[9/4]^2

I will break this up into parts

9^2/4^2

9^2 =81

4^2 =16

81/16

Answer:

option C (3, 2)

Step-by-step explanation:

We have to solve the system of equation by substitution method.

2x + y = 8 ------(1)

y = -x + 5 -------(2)

Now we substitute the value of y from equation (2) to equation (1)

2x + ( -x + 5) = 8

2x - x + 5 = 8

x + 5 = 8

x = 8 - 5

x = 3

Now from equation (2)

y = -x + 5

y = - 3 + 5

y = 2

Therefore, option C (3, 2) will be the answer.

To show that 3/5 and 6/10 are equivalent using a number line, mark both fractions on the number line using tenths. As 3/5 is equal to 6/10, both fractions will land on the same point, confirming their equivalence.

The question is asking us to show that 3/5 and 6/10 are equivalent using a number line. First, let's understand that these are both fractions and are representations of the same value. To show this equivalence on a number line, start by drawing a line and marking it in increments from 0 to 1. You can choose to have 10 ticks, therefore each tick will represent 0.1.

Mark 3/5 on your number line by counting 6 ticks/tenths (because 3/5 is equal to 6/10 when the denominator is 10) from zero. Now, also mark 6/10 on the number line by counting 6 tenths from zero. You will find that both the fractions 3/5 and 6/10 land on the same point on the number line, thus showing they are equivalent.

Mark both fractions on the number line with tenths to demonstrate that 3/5 and 6/10 are equivalent. Because 3/5 equals 6/10, both fractions will settle on the same point, proving their similarity.

The question asks us to use a number line to demonstrate that 3/5 and 6/10 are comparable. To begin, recognize that these are both fractions and represent the same amount. To demonstrate this equivalency on a number line, draw a line and mark it in increments of 0 to 1. You have the option of having 10 ticks, in which case each tick represents 0.1.

Mark 3/5 on your number line by counting 6 ticks/tenths from zero (since 3/5 equals 6/10 when the denominator is 10). Mark 6/10 on the number line as well by counting 6 tenths from zero. Both the fractions 3/5 and 6/10 land on the same point on the number line, indicating that they are comparable.

Answer: Nonlinear

Step-by-step explanation: If the exponent is to a power other than 1, it is nonlinnear.

The area of a circle, represented by the expression 3.14r², is a nonlinear function because the area changes in proportion to the square of the radius, demonstrating a quadratic change rather than a linear one.

The area of a circle is a function of the radius, represented by the expression 3.14r². This represents a nonlinear function because the area of the circle does not change at a constant rate with respect to the radius. Instead, the area changes in proportion to the square of the radius, which is a defining characteristic of a quadratic or second-degree polynomial function, not a linear one.

To further illustrate, let's consider a circle with a radius of 1 inch, which would have an area of approximately 3.14 square inches. If the radius is doubled to 2 inches, the area becomes approximately 4 times larger, not double, because the area is 3.14 * (2²) = 3.14 * 4 square inches. This quadratic change demonstrates the nonlinearity of the area function in relation to the radius.

Answer:

Either 130 or 131 would be acceptable.

Step-by-step explanation:

When we estimate, we do not use exact values.

66.17 is close to 66

44.98 is close to 45

20.15 is close to 20

Add the estimates together: 66+ 45+ 20 = 131

We could also estimate 66.17 to 65 which would give us an estimate of 130

Answer: The total cost would be $ 131.

Step-by-step explanation:

Since we have given that

Amount for bought clothes = $ 66.17

Amount for books = $ 44.98

Amount for meal = $ 20.15

First we add all the amount to get the total cost.

Total cost is given by

$ 66.17 + $ 44.98 + $ 20.15 = $ 131.30 So, the good estimate of $ 131.30 is

$ 130.

Hence, the total cost would be $ 131.

Answer:

4, 4452 scooters were sold

Step-by-step explanation:

Add the number of scooters sold in the previous 3 years.

725 + 679 + 696 = 2100

If In year 4, the store sold 112% of the total number of scooters sold during the previous three years combined, then we have:

2100 (1 + 1.12) = 4452

In Year 4, 4452 scooters were sold

Answer:

2352

Step-by-step explanation:

We are given that:

The number of scooters sold at a store during a three-year period

Year 1-725

Year 2-679

Year 3-696

In year 4,the store sold 112% of the total number of scooters sold during the previous three years combined.

Total scooters sold in previous three years=725+679+696

                                                                       = 2100

the number of scooters sold in year 4=112% of 2100

                                                               = [tex]\dfrac{112}{100}\times 2100[/tex]
