As part of a training program for the Boston Marathon, a runner wants to build endurance by running at a rate of 9 mph for 20 min. How far will the runner travel in that time period?
Answer:
3 miles
Step-by-step explanation
Distance = rate x time
d=rt
rate = 9
time= 20 minutes but we need this in terms of hours since the rate is 9 miles per hour
t = 20/60 = 1/3
so d = 9(1/3) = 3 miles
Can you solve d-3/5=6 before multiplying by 5 reasoning yes or no and why?
Answer:
yes you can
apart from getting rid of the denominator you can collect like terms
Step-by-step explanation:
d=6-3/5
6=30/5
30/5-3/5
27/5
d=27/5

Step-by-step explanation:
A dairy researcher has developed a new technique for culturing cheese that supposedly ages the cheese faster than the traditional methods, without affecting other properties like texture or taste. To implement this new technique, the cheese company would need to initially spend millions of dollars retrofitting their manufacturing plant. But if it does actually reduce the aging time of their cheese, even marginally, it will lead to higher profits for the company over time.In an experiment the researcher uses both methods of culturing cheese to see if the new method significantlyreduces aging time.a.Write an appropriate null and alternative hypothesis for this experiment. (2pt)
Answer:
Null hypothesis: There is no significant difference in aging time of old methods of culturing cheese and the new method of culturing cheese.
Or
H0:μ1=μ2.
Alternative hypothesis: The new method of culturing cheese reduces aging time as compared to old method of culturing cheese
Or
Ha:μ1>μ2.
Step-by-step explanation:
We are interesting in investigating that whether the the new method of culturing cheese significantly reduces aging time compared to old method of culturing cheese. Null hypothesis always contain equality so, in null hypothesis we make the statement of no difference among both methods of culturing cheese. So, null hypothesis can be written as
Null hypothesis: There is no significant difference in mean aging time of old methods of culturing cheese and the new method of culturing cheese.
Or symbolically it can be written as
H0:μ1=μ2
whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.
Alternative hypothesis includes difference in methods which in this case is the claim about new method of culturing cheese reduces aging time. So, it means that mean aging time of old method will be greater than mean aging time of new method. So, the alternative hypothesis can be written as
Alternative hypothesis: The new method of culturing cheese reduces mean aging time as compared to old method of culturing cheese
Or symbolically it can be written as
Ha:μ1>μ2
whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.

Write your answer using only positive exponets.
[tex]x {}^{n} .x {}^{m} = x {}^{n + m} [/tex]
Similarly:[tex]x { }^{ \frac{1}{2} } .x {}^{ \frac{ - 1}{6} } .x {}^{ \frac{ - 5}{2} } = x {}^{ \frac{1}{2} - \frac{1}{6} - \frac{5}{2} } [/tex]
We have to achieve a common denominator which is 6 here:[tex]x {}^{ \frac{3 - 1 - 15}{6} } =x {}^{ \frac{ - 13}{6} } [/tex]
To change our exponent to positive:
[tex]x {}^{ \frac{ - 13}{6} } = \frac{1}{x {}^{ \frac{13}{6}}} = \frac{1}{ \sqrt[6]{x {}^{13} } } = \frac{1}{x \sqrt[6]{x} } [/tex]

Which algebraic expression represents the phrase "seven more than half of a number"?
07-1/2x
0-7+ 1/2x
o 1/2x+7
0-1/2x -7
Answer:
1/2x+7
Step-by-step explanation:
seven more than half of a number is (x/2) + 7.
The correct option is (C).
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
We have to find an algebraic expression which represents the phrase "seven more than half of a number".
Consider a number x,
half of x = (x/2)
seven more than half = (x/2) + 7
Hence, seven more than half of a number is (x/2) + 7.

on a family outing tyler bought 5 cups of hot cocoa and 4 pretzels for $18.50. Some of his family members would like a second serving, so he went back to the same food stand and bought another 2 cups of hot cocoa and 4 pretzels
Answer:
5c+4p = 18.50
2c+4p = 11.20
Cost of cup = $2.4
cost of pretzels = $1.625
Step-by-step explanation:
Note:
2 cups of hot cocoa and 4 pretzels for $11.30
Computation:
5c+4p = 18.50........eq1
2c+4p = 11.30........eq2
Where c = cost of cup
p = cost of pretzels
From eq1 - eq2
3c = 7.20
c = 2.4
Cost of cup = $2.4
5c+4p = 18.50
5(2.4) + 4p = 18.50
p = 1.625
cost of pretzels = $1.625

What is the volume of a matchbox which measures 11cm by 6.4cm by
3cm?5) Small boxes measuring 3cm by 2cm by 1cm are packed into a large box which measures 15cm by 12 cm by 10cm. What is the
volume of:
a) the small boxes?
b) the large box?
c) How many small boxes will fit into the large box?
Step-by-step explanation:
the volume of a box is always
length × width × height
in our first case here :
11 × 6.4 × 3 = 211.2 cm³
the volume of the small boxes is
3 × 2 × 1 = 6 cm³
the volume of the large box is
15 × 12 × 10 = 1,800 cm³
so,
1800/6 = 300 small boxes will fit into the large box.
because the dimensions of the small boxes are factors of the dimensions of the large box (3 is a factor of 15, 2 is a factor of 12, 1 is a factor of 10), it will be a perfect fill without any unused leftover pockets of space.
so, truly 300 small boxes will fit into the large box.
Describe the shape of the given histogram.
The given histogram is uniform histogram.
Since we know that,
A histogram is a graphical depiction of data distribution in statistics. The histogram is represented by a series of neighboring rectangles, with each bar representing a different type of data.
Statistics is a branch of mathematics that is used in a variety of areas. When numbers are repeated in statistical data, this repetition is known as Frequency, and it may be put down in the form of a table, which is known as a frequency distribution.
A Frequency distribution may be represented graphically using several types of graphs, one of which is a Histogram.
Based on the frequency distribution of the data, the histogram may be categorised into distinct categories. Normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distribution, heart cut distribution, and so on are all examples of distributions. These many sorts of distributions can be represented by the histogram.
A histogram can be of several types:
Histogram that is uniform
Histogram with symmetry
Histogram with two modes
Probability distribution histogram
A uniform distribution demonstrates that the number of classes is too small, with the same amount of components in each class. It might involve a distribution with many peaks.
Since we can see in the given histogram,
The average frequency is 5
And almost all the bars are ending at 5
Hence,
This histogram is uniform histogram.
