Which of the following statement justifies why the triangle shown below is not a right triangle?
Answer:
The correct answer is A. [tex]4^{2} +12^{2} \neq 13^{2}[/tex]
Step-by-step explanation:
A right angled triangle is the type of triangle in which one of the three angles is [tex]90^\circ[/tex].
For a triangle to be right angled triangle, following equation must hold:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Height}^{2}[/tex]
Where Hypotenuse is the largest side of triangle and is opposite to the angle with value [tex]90^\circ[/tex].
Base and Height are the two other sides making an angle of [tex]90^\circ[/tex] with each other.
In the given question figure, largest side, XY = 13 units
Other two sides are:
YZ = 4 units
XZ = 12 units
For this [tex]\triangle XYZ[/tex] to be right angled, the following must be true:
[tex]XY^{2} = XZ^{2} + YZ^{2}[/tex]
[tex]XY^{2} = 13^{2} = 169[/tex]
[tex]XZ^{2} + YZ^{2} = 12^{2} + 4^{2}\\\Rightarrow 144 + 16\\\Rightarrow 160[/tex]
[tex]160 \neq 169[/tex]
Hence, the given triangle is not a right angled triangle because of following:
[tex]4^{2} +12^{2} \neq 13^{2}[/tex]
Hence, option A. is correct answer.

20 boxes of apples have been delivered to a restaurant. The number of apples in each box is counted. Complete the table below and answer the following question. What is the mean number of apples in a box?
Answer:
30 apples
Step-by-step explanation:
600 is the total number of apples (adding all numbers in the apples*frequency column). Dividing this by 20, the number of boxes, we get 30 apples as the mean number in a box.
The mean number of apples is the result of dividing the product of frequency and number of apples and f in the table given. Hence, the mean number of apples is 30
The sum of frequency = (2 + 4 + 8 + 4 + 2) = 20
The sum of fx = (56 + 116 + 240 + 124 + 64) = 600
The mean number of apples can be calculated using the values obtained thus :
Mean = fx ÷ f
Mean = 600 ÷ 20
Mean = 30
Therefore, the mean number of apples in a box is 30

A company makes concrete bricks shaped like rectangular prisms. Each brick is 10 centimeters long, 6 centimeters wide, and 4 centimeters cm tall. If they used 13,000cm³ of concrete, how many bricks did they make?
Answer: 54 bricks
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism (V) : length x width x height
Replacing with the values given and solving for v (Volume)
V = 10 x 6 x 4
V = 240 cm3 (volume of one brick)
Finally, we have to divide the amount of concrete used by the volume of each brick:
13,000cm³ /240 cm3 = 54.16 = 54 bricks

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula? P = P V times StartFraction i over 1 minus (1 + i) superscript negative n EndFraction
a.5
b.12
c.60
d.120
The answer is C,60
Answer:
C
Step-by-step explanation:
EDGE2021
The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
What formula is used to calculate the monthly payment?The value of the monthly payment is given by;
P = PV × i / 1-(1+i)⁻ⁿ
Where,
PV is the present value or the amount of the loan.
i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.
Therefore,
The value should be used for n, the number of periods over which the loan is repaid;
n = 6 years × 12 months/year = 60 months = 60 periods.
Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

4. In Kendra's school, 28 percent of seven graders went
to a movie theater over the weekend. If there are 800
students in the seventh grade, how many of them saw
a movie?
Answer:
Step-by-step explanation:
1) Let x represent the sale price.
normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is
25/100 × 39.95 = 9.9875
Sale price = 39.95 - 9.9875 = $29.9625
2) number of games played by the tigers is 11 + 4 = 15
Percentage of games won is
11/15 × 100 = 73.3%
number of games played by the cubs is 10 + 3 = 13
Percentage of games won is
10/13 × 100 = 76.9%
3) increase in stock price = 61.5 - 52.63 = $8.87
Percentage increase = 8.87/52.63 × 100 = 16.85%
4) if 28 percent of seven graders went
to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw
the movie is
28/100 × 800 = 224

Simon offered a customer a cubic box with 3-inch sides. The customer told Simon to increase each side of the box by an inch
Answer:
64 [tex]in^{3}[/tex]
Step-by-step explanation:
The volume of a cubic box with side length of s inches can be calculated using the following formula
[tex]V = s^{3} in^{3}[/tex]
If the initial side length was 3 inches and the customer asked Simon to increase each one of the sides of the box by one inch, then the new side lengths now become 4 in (3+1 = 4)
[tex]V = 4^{3} in^{3} = 64 in^{3}[/tex]
Therefore the final and new volume is
64 [tex]in^{3}[/tex]
Answer:
The volume of the new box is 64 cubic inches. If each side of the box was increased by 1 inch, the new measure of each side would be 4 inches. 4 times 4 times 4 equals 64.

Of 136 randomly selected adults, 33 were found to have high blood pressure. Construct a 95% confidence interval for the true of all adults that have high blood pressure.
Answer:
The 95% confidence interval of the proportion of all adults that have high blood pressure is 0.17059 < [tex]\hat{p}[/tex] < 0.314695
Step-by-step explanation:
The confidence interval for a proportion is given by the following formula;
[tex]CI=\hat{p}\pm z\times \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]
Where:
x = 33
n = 136
[tex]\hat{p}[/tex] = x/n = 33/136 = 0.243
z value for 95% confidence is 1.96
Plugging in the values, we have;
[tex]CI=0.243\pm 1.96\times \sqrt{\frac{0.243(1-0.243)}{136}}[/tex]
Which gives;
0.17059 < [tex]\hat{p}[/tex] < 0.314695
Hence the 95% confidence interval of the proportion of all adults that have high blood pressure = 0.17059 < [tex]\hat{p}[/tex] < 0.314695
From the above we have;
23.2 < x < 42.798
Since we are dealing with people, we round down as follows;
23 < x < 42.

A chemical company makes two brands of antifreeze. The first brand is 40%pure antifreeze, and the second brand is 90%pure antifreeze. In order to obtain 160
Complete question:
A chemical company makes two brands of antifreeze. The first brand is 40% pure antifreeze, and the second brand is 90% pure antifreeze. In order to obtain 160 gallons of a mixture that contains 60% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Answer:
Amount of 40% pure antifreeze = y = 96gallons
Amount of 90% pure antifreeze = ((160-y) = (160 - 96) = 64gallons
Step-by-step explanation:
Brand A = 40% pure
Brand B = 90% pure
Therefore to obtain 160 gallons that contains 60% pure antibfreeze:
Let y = Amount of 40% pure antifreeze required
Therefore (160 - y) = Amount of 90% pure antifreeze required.
Expressing mathematically,
0.4y + (160 - y) (0.9) = 160×0.6
0.4y + 144 - 0.9y = 96
-0.5y = 96 - 144
-0.5y = - 48
y = 48 / 0.5
y = 96
Amount of 40% pure antifreeze = y = 96gallons
Amount of 90% pure antifreeze = ((160-y) = (160 - 96) = 64gallons

Two sides of an obtuse triangle measure 10 inches and 15 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side? 18 inches 19 inches 24 inches 25 inches
Answer:
19 inches is the correct answer.
Step-by-step explanation:
Side 1 = 10 inches
Side 2 = 15 inches
It is given that it is an obtuse angle triangle i.e. the largest angle of the triangle is more than [tex]90^\circ[/tex].
Let us suppose, that the triangle be a right angle triangle, then the largest angle will be [tex]90^\circ[/tex]. The largest side is known as Hypotenuse.
As per pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\Rightarrow 10^{2} + 15^{2} = Hypotenuse^2\\\Rightarrow 325 = Hypotenuse^2\\\Rightarrow Hypotenuse = 18.04\ inches[/tex]
So, largest side comes out be 18.04 inches.
But actually, the largest angle is more than [tex]90^\circ[/tex] so the largest side will also be greater than 18.04 inches.
Hence, the answer is:
Smallest possible whole number length of unknown side will be 19 inches.
