B. 247.50
C. 234
Answer:
C
Step-by-step explanation:
use Pythagorean theorem to get the missing side of the triangle as 12.
Find the area of the triangle and add ot to the area of the rectangle...so (9)(12)/2=54 for area of triangle + area of rectangle is (15)(12)=180. so 54 + 180 = 234
Due to manufacturing error, three cans of regular soda were accidentally filled with diet soda and placed in a 12-pack. Suppose that two cans are randomly selected from the 12-pack: a) Determine the probability that both contain diet soda. b) Determine the probability that exactly one is diet
Answer:
a) 2/44 = 0.045
b) 9/22 = 0.409
Step-by-step explanation:
a) The probability the first can is diet soda is 3/12.
The probability the second can is diet soda is 2/11.
The probability of both is (3/12) (2/11) = 2/44 ≈ 0.045.
Alternatively, you can use combinations:
₃C₂ × ₉C₀ / (₁₂C₂) = 2/44
b) If the first can is diet soda, and the second can isn't, the probability is (3/12) (9/11) = 9/44.
If the first can isn't diet soda, and the second can is, the probability is (9/12) (3/11) = 9/44.
The total probability is 9/44 + 9/44 = 9/22 ≈ 0.409.
Alternatively, using combinations:
₃C₁ × ₉C₁ / (₁₂C₂) = 9/22

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.

Find the quotient of 2 7/8 and 3 5/6
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Given the following question:
[tex]2\frac{7}{8} \div3\frac{5}{6}[/tex]
To find the answer we need to convert the mixed numbers into improper fractions, then we apply KCF (Keep, Change, Flip) to the equation and then we solve.
[tex]2\frac{7}{8} \div3\frac{5}{6}[/tex]
[tex]2\frac{7}{8} =8\times2=16+7=23=\frac{23}{8}[/tex]
[tex]3\frac{5}{6} =6\times3=18+5=23=\frac{23}{6}[/tex]
[tex]\frac{28}{8} \div\frac{23}{6}[/tex]
Apply KCF:
[tex]\frac{28}{8} \div\frac{23}{6}[/tex]
[tex]\frac{28}{8} \times\frac{6}{23}[/tex]
[tex]28\times6=168[/tex]
[tex]8\times23=184[/tex]
[tex]=\frac{168}{184}[/tex]
Simplify by reducing:
[tex]\frac{168}{184}[/tex]
[tex]=\frac{168}{184}\div46=\frac{3}{4}[/tex]
[tex]=\frac{3}{4}[/tex]
Your answer is "3/4."

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.

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

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
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.

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 22.5%, and the final exam is worth 32%. Compute the weighted average for the following scores: 85 on the lab, 95 on the first major test, 91 on the second major test, and 76 on the final exam. (Enter your answer to one decimal place.)
Answer:
The weighted average for the following score is [tex]W = 85.72[/tex]
Step-by-step explanation:
From the question we are told that
The worth of the lab score is 23% of total grade i.e 0.23
The worth of each major test is 22.5% of the total grade 0.225
The worth of the final exam is 32% of the total grade 0.32
The score on lab is 85
The score on first major test is 95
The score on the second major test is 91
The score on the final exam is 76
Generally the weighted average is mathematically represented as
[tex]W = [0.23 * 85 ]+ [0.225 * 95] + [0.225 * 91 ]+ [0.32 *76 ][/tex]
=> [tex]W = 85.72[/tex]

write an equation of the line below
Answer:
y = 3/5 + 4
Step-by-step explanation:
Given Coordiantes:
(0,4) - Y-intercept
(5,7) - Coordinates
To make an equation, first find the slope.
[tex]m=\frac{rise}{run} =\frac{y}{x}[/tex]
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m=\frac{7-4}{5-0}[/tex]
[tex]m=\frac{3}{5}[/tex]
In decimals:
[tex]m = 0.6[/tex]
Now convert to point slope.
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y-4=\frac{3}{5} (x-0)[/tex]
In decimals:
[tex]y-4=0.6(x-0)[/tex]
Now convert to slope-intercept form.
Find the Equation of the Line:
[tex]y=mx+b[/tex]
by solving for y using the Point Slope Equation.
y = 3/5 + 4
