Answer:
52 cats
Step-by-step explanation:
Let d be the number of dogs, then c = 2d + 10 is the number of cats.
The total number of animals is 73, so we have d + c = 73.
Substituting c = 2d + 10 into this equation, we get d + 2d + 10 = 73.
Combining like terms, we get 3d + 10 = 73.
Solving for d, we have 3d = 63, so d = 21.
Thus, there are 21 dogs and 2 * 21 + 10 = 52 cats up for adoption.
what is the volume of the parallelepiped with sides i, 7j − k, and 9i 6j − k?
The volume of the parallelepiped is 63 cubic units.
The volume of a parallelepiped is the amount of space it takes up. It is calculated by multiplying the lengths of its three sides together.
In this case, the parallelepiped has three sides: i+0j+0k, 0i+7j − k, and 9i+6j − k.
To find the volume, we will use the cross product of two of the vectors. The cross product of two vectors results in a third vector that is perpendicular to both.
The cross product of the first two vectors,
=> (i+0j+0k) x (0i+7j − k) = 7i − 7j − 0k.
The cross product of this vector and the third vector,
=> 9i+6j − k,
results in the vector
=> 63i + 63j − 63k.
The magnitude of this vector is the volume of the parallelepiped.
To calculate the magnitude, we use the Pythagorean theorem and find that it is equal to 63.

If angle eight is 30°, what is the measurement of angle 5
The measurement of angle 5 is given as follows:
m < 5 = 150º.
How to obtain the measurement of angle 5?In this problem, we have that two parallel lines are cut by a transversal line.
Angles 5 and 8 are on the same position relative to the transversal line, separated by one of the parallel lines, hence they form a linear pair, meaning that they are supplementary.
Supplementary angles have the sum of their measures with a result of 180º, hence the measurement of angle 5 is obtained as follows:
m < 5 + 30º = 180º
m < 5 = 150º.

Match the following MATLAB command to its mathematical meaning log(x) Choose) log 10(x) [Choose) In(x) [Choose] log base 10 of Not a valid MATLAB command log base e of x (log base d of x)/(log base d of b)
The Logarithmic function is a mathematical operation that is used to determine the logarithm of a number.
The logarithm of a number x is the exponent to which a fixed number, the base, must be raised to produce x. The most common bases used are 10 and e. The formula for determining the logarithm of a number x base d is: log base d of x = (log base d of x)/(log base d of b).
For example, if we want to calculate the log base 10 of a number x, we would use the formula: log base 10 of x = (log base 10 of x)/(log base 10 of b). We can calculate the log base 10 of a number x by taking the logarithm of x and dividing it by the logarithm of the base, 10. The result will be the log base 10 of x.
For example, if we want to calculate the log base 10 of 25, we would calculate the logarithm of 25 and divide it by the logarithm of 10. The calculation would be: log base 10 of 25 = (log base 10 of 25)/(log base 10 of 10) = (1.3979)/(1) = 1.3979. This means that the log base 10 of 25 is 1.3979.

The volume of a bead is a measure of the amount of space it occupies. In mathematics, we often use the formula for the volume of a sphere to calculate the volume of a bead.
In this case, the bead has two parameters: the radius (r) and the height (h). The radius determines the size of the bead while the height determines the length of the cylinder that makes up the bead.
When r = 1 and h = 6, we can substitute these values into the formula for the volume of a sphere to find the volume of the bead:

Ratio: Because it has a meaningful zero point and allows for meaningful comparison of value differences, the volume of a backpack is a ratio level of measurement.
Ratio: A backpack's capacity is a ratio level of measurement because it has a meaningful zero point, or when an item (in this case, capacity) is absent, it has a value of zero. Additionally, it is possible to meaningfully compare value differences. As opposed to other levels of measurement like nominal or ordinal where the differences between two values may not be relevant, this means that differences in capacity between two backpacks may be compared properly.
For instance, the difference between two backpacks can be considered to be twice as great if one backpack has a capacity of 20 litres and the other has a capacity of 40 litres (20 liters).

please help !!!!!!!!!
The length of the other sides are 5cm and 12cm
How to determine the other sidesLet the legs of the right triangle be 'a' and 'b'. Let the hypotenuse be 'h'.
We have the formula for perimeter as;
Perimeter, p = a + b + h = 30 cm
p = a + b + 13 cm = 30 cm
a + b = 30 - 13 = 17 cm
a = 17 - b …………… (1)
Using the Pythagorean Theorem
a² + b² = h²
(17 - b)² + b² = 13² ................ From equation (1)
b² + 17² - 34b + b² = 169
2b² - 34b + 289 - 169 = 0
collect like terms
2b² - 34b + 120 = 0
b² - 17b + 60 = 0
solve the quadratic equation
b² - 12b - 5b + 60 = 0
b(b - 12) - 5(b - 12) = 0
Factor the like terms
(b - 12)(b - 5) = 0
b = {12, 5}
From equation (1), we have;
a = 17 - 12 = 5 cm, or a = 17 - 5 = 12 cm
a = {5,12}

The critical point (0, 9) is a minimum and (0, -9) is a maximum.
Lagrange multipliers are a method used to find the maximum and minimum values of a function subject to a constraint.
To use Lagrange multipliers, we first write the function and constraint as a system of equations.
For the function
=> f(x, y) = y² − x²
and the constraint
=> 14x²y² - 81,
the system becomes:
y² − x² = λ(14x²y² − 81)
Next, we find the partial derivatives of both equations with respect to x and y and set them equal to zero to find the critical points.
Solving for x and y, we find that (0, ±9) are the critical points.
If the value is zero, the critical point is a saddle point.

What is the probability of finding an average in excess of 4. 3 ounces of this ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline?
The probability of finding an average in excess of 4. 3 ounces of this ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline is approximately 0.7972.
We may use the normal distribution and the Z-score to determine the likelihood that 100 randomly selected 1-gallon samples of standard unleaded gasoline will have an average of more than 4.3 ounces of the component. A value's Z-score indicates how many standard deviations away from the mean it is.
We must first get the average of 100 randomly chosen samples' mean and standard deviation. The average's mean will be 4 ounces, which is also the mean of the individual samples. The sample size is divided by the square root of the standard deviation to get the average standard deviation, which is 1.2/100 = 0.12 ounces.
Next, we calculate the Z-score for the value of 4.3 ounces:
Z = (4.3 - 4) / 0.12 = 0.83
Finally, we use a Z-score table or a normal distribution calculator to find the probability of finding an average in excess of 4.3 ounces. The result will be the area under the standard normal distribution curve to the right of 0.83.
There is a 79.72% chance of finding an average in excess of 4.3 ounces of the ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline.

object a has a charge of 2 µc, and object b has a charge of 6 µc. which statement is true?
Object A has a charge of 2 µc, and object B has a charge of 6 µc. Object B has a charge that is three times greater than object A.
Object A has a charge of 2 µc, and object B has a charge of 6 µc. To determine which statement is true, we need to compare the two charges. To do this, we can divide the charge of object B by the charge of object A. When we do this, the result is 3. This tells us that object B has a charge that is three times greater than object A. Therefore, we can conclude that the statement "Object B has a charge that is three times greater than object A" is true. Now that we know the statement is true, we can further explain why it is true. Object A has a charge of 2 µc, which is the smallest unit of charge and is equal to 10−6 coulombs. Object B has a charge of 6 µc, which is three times greater than the charge of object A. This means that the charge of object B is three times larger than the charge of object A. This is why the statement is true - because object B has a charge that is three times greater than object A.
