Tony rode his bicycle 3 7/10 miles to school. What is this distance written as a decimal?
Answer:
The distance written as a decimal is 3.7
To write 3 7/10 miles as a decimal, multiply the whole number by the denominator and add the numerator, then write the result over the denominator. Simplify the fraction if possible.
Explanation:To write the distance in decimal form, we need to convert the mixed number to a decimal. The given distance is 3 7/10 miles. To do this, we multiply the whole number, 3, by the denominator, 10, and add the numerator, 7. So, 3 multiplied by 10 plus 7 equals 37. Then, we write 37 over the denominator 10, giving us 37/10. Finally, we can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which in this case is 1. Dividing 37 by 1 gives us 37, and dividing 10 by 1 gives us 10. Therefore, the distance of 3 7/10 miles can be written as the decimal 3.7 miles.

Evaluate C(7, 3). 4 35 70
Answer:
option B
35
Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Formula to calculate combination
nCr = n! / r! * (n - r)!
We are given C(7,3)
here n = 7
r = 3
So plug values in the formula7C3 = 7! / 3! * (7 - 3)!
= (7x6x5x4x3x2) / (3x2)(4x3x2)
= (7x6x5) / (3x2)
= 210 / 6
= 35
Final answer:
The value of C(7, 3), which is the number of combinations of 7 items taken 3 at a time, is 35. The calculation uses the combinations formula C(n, k) = n! / (k! * (n - k)!), simplifying the factorials and the result is determined.
Explanation:
To evaluate C(7, 3), we need to calculate the number of combinations of 7 items taken 3 at a time. The formula for a combination is given as:
C(n, k) = n! / (k! * (n - k)!)
Here, n represents the total number of items and k represents the number of items to choose. Let's plug in the values to calculate this:
C(7, 3) =[tex]7! / (3! * (7 - 3)!) = 7! / (3! * 4!)[/tex] = (7 x 6 x 5 x 4 x 3 x 2 x 1) / ((3 x 2 x 1) * (4 x 3 x 2 x 1))
After canceling the matching factorial terms, we get:
C(7, 3) = (7 x 6 x 5) / (3 x 2 x 1) = 210 / 6 = 35
Therefore, the value of C(7, 3) is 35.
What is the experimental probability that the next customer buys a red notebook 150 pages.
red green blue yellow
100 pg-55 37 26 12
150 pg-60 40 57 27
200 pg-23 19 21 19
Answer:
5/33
Step-by-step explanation:
The table with proper formatting is attached in the image below.
We have to calculate the experimental probability that the next customer buys a red notebook with 150 pages.
Total number of customers in the experiment = Sum of all the values in the given table = 396
Number of customers who bought red notebook with 150 pages = 60
Experimental probability = [tex]\frac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}[/tex]
Number of favorable outcomes in the experiment were 60 and the total outcomes in the experiment were 396.
Therefore, the probability that next student buys a red notebook with 150 pages will be 60/396 = 5/33
The experimental probability that the next customer buys a red notebook with 150 pages is approximately 0.326 or about 32.6%, calculated by dividing 60 red 150-page notebooks sold by the total 184 notebooks sold of that size.
The student is asking about the experimental probability that the next customer will buy a red notebook with 150 pages. To determine this probability, one must look at past data to find the frequency with which customers have purchased red notebooks of 150 pages and divide this by the total number of notebook purchases of all colors with 150 pages.
Based on the data provided:
Number of red 150-page notebooks sold: 60Total number of 150-page notebooks sold: 60 (red) + 40 (green) + 57 (blue) + 27 (yellow) = 184The experimental probability is therefore calculated as follows:
P(red 150-page notebook) = Number of red 150-page notebooks sold / Total number of 150-page notebooks sold
P(red 150-page notebook) = 60 / 184
P(red 150-page notebook) = 0.326 or about 32.6%

The answer choices are
A. 93
B. 31
C. 69
D. 300
Answer:
A
Step-by-step explanation:
We obviously can take out D and B, as roses are 31% while carnations are 19%. Since roses have a larger percentage, it obviously can't be less than carnations but 300 is beyond the logical answer. This leaves us with 69 or 93. 19% is 57, so a 12 percent rise will not equal an increase of only 12 flowers. Therefore, without even any calculations, I can confidently tell you that your answer is A.

Factor & Finding Zeros
x^{2} -x-6=0
Answer:
x = 3, -2
Step-by-step explanation:
To help us factor, we can split the middle term up into the sum of the terms -3x and 2x:
[tex]x^2+(-3x)+2x-6=0[/tex]
From there, we can factor out an x from the first two term and a 2 from the last two to obtain the equation
[tex]x(x-3)+2(x-3)=0[/tex]
Factoring out an (x - 3) from each term gives us the equation
[tex](x-3)(x+2)=0[/tex]
At this point, we can divide by either x - 3 or x + 2 to obtain the two equations
[tex]x-3=0[/tex] and [tex]x+2=0[/tex]
Solving both for x gives us the solutions x = 3 and x = -2. We can verify these by substituting them back into the original equation:
[tex]3^2-3-6=0\\9-3-6=0\\6-6=0\\0=0[/tex]
[tex](-2)^2-(-2)-6 = 0\\4+2-6=0\\6-6=0\\0=0[/tex]

Which of the following describes a point?
A. one dimensional
B. zero dimensional
C. three dimensional
D. two dimensional
(B) Zero-dimensional describes a point.
What is the point?A point has no length, area, or volume and is, therefore, zero-dimensional.Two-dimensional:A flat plane figure or a shape with two dimensions—length and width—are both considered two-dimensional shapes in geometry. Shapes that are two-dimensional, or 2-D, have only two faces and no thickness. The proportions of a figure can be used to categorize it.Two-dimensional shapes include the triangle, square, rectangle, pentagon, and circle.Three-dimensional:Three values are needed to locate an element in three-dimensional space, which is a geometric setting. This is how the term "dimension" is generally used. A tuple of n numbers in mathematics is equivalent to the Cartesian coordinates of a point in an n-dimensional Euclidean space.Therefore, the correct answer is (B) Zero dimensional because it cannot be one or zero dimensions, since a vector is a three-dimensional point.

Work out the base of a square with area, A = 4cm2.
Answer:
each side of the square is 2cm
To find the base of a square with an area of 4 cm², we take the square root of the area. The base of the square is 2 cm because the square root of 4 is 2.
To work out the base of a square with an area of 4 cm², we note that a square's area is calculated by multiplying one of its sides by itself, which is represented as side length² or a². Given that a square's area is 4 cm², we set up the equation a² = 4 cm². Solving for a, we take the square root of both sides of the equation. The side length a is thus 2 cm, since the square root of 4 is 2. Therefore, the base of the square is 2 cm.

No, we cannot determine the order of the set of rational numbers because we only know their absolute values, not their signs. The answer is option C.
The question is asking whether we can determine the order of a set of rational numbers given their absolute values. The answer to this is option C: No, it is not possible to determine the order of the rational numbers because we do not know the signs of the rational numbers. Knowing only the absolute values does not give us any information about whether the original rational numbers were positive or negative. Absolute value only indicates the magnitude of a number, not its sign, therefore without this information, the original sequence of the rational numbers cannot be determined.

Which graph shows how his distance covered varies with time?
A)B)C)D)
Answer:
graph a
Step-by-step explanation:
you have to look at the numbers carefully and that was the only graph that showed everything
Answer:
Step-by-step explanation:
Jerry is driving at a steady speed on an highway.
After 2.5 hours he has driven = 150 miles.
speed = [tex]\frac{150}{2.5}[/tex] = 60 miles/hour
then after 5.5 hours he has covered 330 miles.
speed = [tex]\frac{330}{5.5}[/tex] = 60 miles/hour
Total time he has driven = 2.5 + 5.5 = 8 hours
total distance he covered = 150 + 330 = 480 miles.
Therefore, after 2.5 hours he covered 150 miles and after 8 hours he covered 480 miles with an steady speed of 60 miles/hour.
Graph A shows his constant speed and his distance covered varies with time.
