how do you divide fractions
Dividing fractions is basically the same thing as multiplying fractions but by the reciprocal.
For example, [tex]\frac{3}{8}[/tex] ÷ [tex]\frac{1}{4}[/tex] you would change this so in the second fraction that is being divided, the numerator and the denominator would switch places. Instead, it would be...
[tex]\frac{3}{8}[/tex] x [tex]\frac{4}{1}[/tex]
Can you determine the number of digits in the quotient of 637 divided by 7 without dividing?explain.

if angle m acd = 100 and angle m b =60, find angle m a
Answer:
The measure of ∠BAC is 40° .
Step-by-step explanation:
As given the figure in the question be as follow .
∠ACD = 100° , ∠B = 60°
Noe by using the the exterior angle is equal to the sum of the interior angle .
Thus
∠ACD = ∠CBA + ∠BAC
Put all the values in the above
100° = 60° + ∠BAC
∠BAC = 100° - 60°
= 40°
Therefore the measure of ∠BAC is 40° .

Answer:
i = [tex]\sqrt{-1}[/tex]
Step-by-step explanation:
A complex number is that one having two parts:
One called real part, represented by a.And another called imaginary part, represented by bi, where b is also a real number plus i, as it was describe in the answer [tex]i = \sqrt{-1}[/tex].Although [tex]i =\sqrt{-1}[/tex], it is also [tex]i^{2} = -1[/tex], which has some interesting properties like [tex]i^{3}[/tex] = [tex]i * i^{2}= i * -1 = -i [/tex] , and so on.
These numbers came along when it was necessary to take the squared root of negative numbers:
[tex]\sqrt{-4} = \sqrt{-1} * \sqrt{4} = 2i ; -2i[/tex] .
Which expression is equivalent to (3−22)+5 ?
A. 22−5
B. 5−32
C. 32−5
D. 5−22
The expression (3-22)+5 simplifies to -14. None of the provided options: A. 22-5, B. 5-32, C. 32-5, or D. 5-22 are equivalent to the original expression.
Explanation:Let's break this question down for you. The initial expression given is (3−22)+5. In math, operations inside the parentheses are performed first according to the order of operations (PEMDAS/BODMAS), which is followed by addition or subtraction. However, the expression inside the parentheses here results in a negative number, since 3−22 equals -19. Then add 5 to -19 gives you -14.
So, the none of the options A, B, C or D are equivalent to the original expression (3−22)+5.
It's important to understand order of operations in math because it helps to ensure that calculations are done correctly and consistently.

none of the provided options (A, B, C, or D) match this value.
We start with the given expression (3−22)+5. It can be simplified step-by-step as follows,
Calculate inside the parentheses first: 3 - 22.
Since subtracting 22 from 3 is performed, we get: 3 - 22 = -19.
Next, add 5 to the result: -19 + 5 = -14.
Let's evaluate each of the provided options:
A. 22−5: This evaluates to 17, which does not match -14.
B. 5−32: This simplifies to 5 - 9 = -4, which does not match -14.
C. 32−5: This evaluates to 9 - 5 = 27, which does not match -14.
D. 5−22: This simplifies to 5 - 22 = -17, which does not match -14.
None of the provided expressions are equivalent to (3−22)+5. Therefore, the correct answer is: None of the above.

$10,000 is compounded semiannually at 12% interest for t years. what expression represents the amount of money after t years?
The expression that represents the amount of money after t years when $10,000 is compounded semiannually at 12% interest is [tex]10000(1.06)^{(2t)}[/tex].
The amount of money after t years can be represented by the following expression:
[tex]A = P(1 + \frac{r}{n})^{(n*t)}[/tex]
Where:
A is the amount of money after t years
P is the principal amount (initial investment), which is $10,000 in this case
r is the interest rate, which is 12% expressed as a decimal (0.12)
n is the number of times interest is compounded per year, which is semiannually (2 times per year)
Substituting the values into the expression, we have:
[tex]A = 10,000(1 + \frac{0.12}{2})^{(2*t)}[/tex]
Simplifying further, we get:
[tex]A = 10000(1.06)^{(2t)}[/tex]
Therefore, the expression that represents the amount of money after t years when $10,000 is compounded semiannually at 12% interest is [tex]10000(1.06)^{(2t)}[/tex].

which inequality best represents the situation of you must be at least 52 inches tall to ride the water ride
Answer:
Option C is the correct choice.
Step-by-step explanation:
We have been given a graph and we are asked to find the correct option which represents the inequality for the situation of one must be at least 52 inches tall to ride the water ride.
At least 52 inches means one should not be less than 52 inches. This means the length of one should be 52 inches or any number greater than 52 inches.
Let us see our given inequalities one by one.
A) Our first inequality represents height less than or equal to 52, which means that one should be at-most 52 inches, therefore, 1st inequality is not true for our given situation.
B) Our 2nd inequality represents height less than 52, therefore, 2nd inequality is not true for our given situation.
C) We can see from our inequality represented in option C that height is greater than or equal to 52 inches. It is including 52 (at least) and greater heights than 52, therefore, option C is the correct choice.
D) Option D shows an inequality that represents heights greater than 52 as it is not including 52, therefore, option D in not a correct choice.
If you flip the graph of the quadratic parent function, f(x) = x2, over the x-axis, what is the equation of the new function?
A. g(x) = –x2
B. g(x) = x–2
C. g(x) = (–x)2
D. g(x) =
Answer:
A. [tex]g(x)=-x^2[/tex]
Step-by-step explanation:
In flipping across x-axis a function gives its mirror image through the x-axis,
That is, when a function f(x) is flipped over x-axis,
Then the new function would be -f(x).
Here, the given function,
[tex]f(x)=x^2[/tex]
After flipping the function over x-axis,
[tex]g(x)=-f(x)[/tex]
[tex]\implies g(x)=-x^2[/tex]
Hence, option 'A' is correct.

if the x intercept of a line is positive and the y intercept is negative, does the line slant upwards or downwards from left to right?
If the x-intercept of a line is positive and the y-intercept is negative, the line will slant downwards from left to right.
Explanation:The line will slant downwards from left to right. The x-intercept being positive means that the line crosses the x-axis at a point to the right of the origin. The y-intercept being negative means that the line crosses the y-axis at a point below the origin. Since the slope of a line represents the direction and steepness of the line, a positive slope combined with a negative y-intercept indicates a line that slants downwards.

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 108.7-cm and a standard deviation of 0.6-cm. For shipment, 22 steel rods are bundled together.
Find the probability that the average length of rods in a randomly selected bundle of steel rods is less than 109.1-cm.
Round to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 2 decimal places are accepted.
Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
