One of the legs of a right triangle measures 9 cm and the other leg
measures 4 cm. Find the measure of the hypotenuse. If necessary,
round to the nearest tenth.
Answer:
9.8cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2}+b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 9cm
b = 4cm
c = hypotenuse
9^2 + 4^2 =c^2
81 + 16 = c^2
[tex]\sqrt{97} =c[/tex]
9.8 = c

What is the price of a can of soda if a case of 24 is 8.99
Answer:
Discount:
20% is .2 as a decimal, so you multiply the value of 12 by .2
12(.2)=2.4
The discount is $2.40
Sale Price:
subtract 2.4 from the price of the original price
12-2.4=9.6
The sale price is $9.60
Step-by-step explanation:
Answer:
Each can of soda will cost $0.37
Step-by-step explanation:
First you write 24/8.99 = 1/x because you are trying to find the cost for 1 soda
24/8.99 = 1/x
Then you cross multiply.
24*x 8.99*1
24x=8.99
Divide each side by 24
24x/24=8.99/24
x=0.374583
Round it to the nearest hundredths place.
x=0.37
A player at a basketball camp set a goal to make 55% if his shots. If he has 120 attempts, how many shots would he need to make in order to reach his goal?
Answer: 66
Step-by-step explanation:
From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.
The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:
= 55% × 120
= 55/100 × 120
= 0.55 × 120
= 66
He would need to make 66 shots

The correlation of the values in the tables is the existence of a
relationship between the x and y values.
Correct response:
The third table.Method used for the evaluation of the tablesA table that shows a strong correlation is one in which the y-values can be predicted more or less accurately from the x-values.
The table that shows no correlation is one in which the x and y-values have different patterns;
The level of correlation is given by the correlation coefficient, which is found by the following formula;
[tex]\displaystyle r = \mathbf{ \dfrac{\sum \left(x_i - \overline{x} \right) \cdot \left(y_i - \overline{y} \right)}{\sqrt{\sum \left(x_i - \overline{x} \right)^2 \cdot \sum \left(y_i - \overline{y} \right)^2} }}[/tex]
By plotting the values using MS Excel, we have the values of r², for the tables as follows;
The value of r² for the first table is r² = 0.7307
Therefore;
r ≈ 0.8548 The correlation of the first table is strong.
Second table, r² = 0.8156
r = √(0.8156) ≈ 0.9031 The correlation in the second table is very strong.
Third table, r² = 0.0107
Therefore, r ≈ 0.1034
The correlation for the third table is weak, which shows no correlation.Fourth table, r² = 0.9342
Therefore, r ≈ 0.9665
The correlation of the x and y-values of the fourth table is very strong indicating the presence of a correlation.
Therefore;
The table that shows no correlation is the third table.Learn more about correlation analysis here:

Step-by-step explanation:
Carl rented a bounce house for his little brother's birthday party. The company charges a base rental charge of $95.25, plus a certain amount per hour. Carl's little brother's party lasted 4 hours, and costs $179.72. Carl plans to rent a bounce house for his little sister's birthday party for 6 hours for about $200. Is this a reasonable estimate? A. Yes, the estimate is reasonable. B. No, the estimate should be lower. C. No, the estimate should be higher.
Answer:
C. No, the estimate should be higher.
Step-by-step explanation:
Carl's brother party
Fixed charge = $95.25
Number of hours = 4 hours
Hourly charge = x
Total cost = $179.72
179.72 = 95.25 + 4x
179.72 - 95.25 = 4x
84.47 = 4x
x = 84.47/4
x = 21.1175
Hourly charge = $21.1175
Carl's little sister party
Estimated total charge = $200
Number of hours = 6
Fixed charge = $95.25
Hourly charge = $21.1175
Total charges = 95.25 + 6(21.1175)
= 95.25 + 126.705
= 221.955
Total charges = $221.955
C. No, the estimate should be higher

A creature on the moon throws a rock off a cliff. The height of the rock above the surface of the moon, in meters, t seconds after it is thrown is given by h(t) = −t 2 + 8t + 10. When does the rock hit the surface of the moon?
Answer:
9.099 seconds
Step-by-step explanation:
The rock hits the surface of the moon when is t is 0.
[tex]-t^2 + 8t + 10 = 0\\t^2 - 8t - 10 = 0[/tex]
Use the quadratic formula
t = -1.099 and 9.099
Since time can't be negative, the answer is t = 9.099
"complete the function table. use the given input (x) values and determine the corresponding output (y) values based on the given function. if no inputs or outputs are given --- provide your own."
Answer:
-4, 6, 16, 26
Step-by-step explanation:
For each y-value, all you need to do is put x into the function or equation wherever there is an x, and the result will be the y-value.
When x = 0; y = 2(0)-4, or y = -4.
When x = 5; y = 2(5)-4 = 10-4 = 6
When x = 10; y = 2(10)-4 = 20-4 = 16
When x = 15; y = 2(15)-4 = 30-4 = 26

A rectangular prism has a base area of 380 square feet. The volume of the prism is 4180 cubic feet. What is the height of the prism?
Answer:
the height will be 11 cm
Step-by-step explanation:
As:
given,
base area = 380
volume = 4180
We know,
Base area = l * w
or, 380 = l * w
Then,
volume= l * w * h
or, 4180 = 380 * h
or, 4180/380 = h
or, h = 11
Therefore, the height will be 11 ft.
All the best!!
The height of the rectangular prism is 11 feet
The volume of the prism is given as:
Volume = 4180 cubic feet
The base area of the prism is given as:
Base Area = 380 square feet
The volume of the prism is calculated as:
[tex]Volume = Bh[/tex]
Where, B represents the base area and h represents the height
So, we have:
[tex]4180= 380 \times h[/tex]
Divide both sides by 380
[tex]11 = h[/tex]
Rewrite the equation as:
[tex]h =11[/tex]
Hence, the height of the rectangular prism is 11 feet

What is matrix?"A set of numbers arranged in rows and columns so as to form a rectangular array."
What is augmented matrix?"A matrix formed by combining the columns of two matrices to form a new matrix."
What are elementary row operations?"The mathematical operations that are performed on rows of a matrix."
For given question,
We have been given an augmented matrix.
[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]
We need to perform the row operation 4R3 + R1 → R1
To perform above row operation,
- First multiply the third row by 4. ([tex]4R_3[/tex])
- Add the new third row (4[tex]R_3[/tex]) with the first row.
- Then replace Row 1 with the result.
The resultant augmented matrix would be,
[tex]\begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]
That is,
[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]
Now, we need to perform the row operation [tex]\frac{1}{4}[/tex] R1 → R1 on the above resultant augmented matrix.
To perform above row operation,
- Multiply the Row 1 by the reciprocal of 4.
- Then replace Row 1 with the result.
The resultant augmented matrix would be,
[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

On January 29, 2019, Australian authorities confiscated 157.7 kilograms of heroin with an estimated street value of 77 million AUD (Australian dollars). The exchange rate at the time was 1 USD = 1.42 AUD. Based on this information, what was the value in U.S. Dollars per pound for the heroin? Round your answer to the nearest thousand dollars.
Answer: $343849
Step-by-step explanation:
Since the exchange rate at the time was 1 USD = 1.42 AUD, therefore we will convert 77 million AUD to dollars which will be:
= 77 million / 1.42
= $54.225 million
Therefore, the value in U.S. Dollars per pound for the heroin will be:
= $54.225 million / 157.7
= $343849 pee pound
