The total amount Toni spent on shirts is $64. If you rewrite 64 using 2 as the base, what would be the exponent?
To rewrite 64 using 2 as the base, the exponent is 6.
Explanation:To rewrite 64 using 2 as the base, we need to find the exponent that represents the power of 2 that equals 64. In other words, we need to solve the equation 2 to the power of x equals 64. We can do this by finding the logarithm with base 2 of 64. Using a calculator, we find that log base 2 of 64 is 6. Therefore, the exponent is 6.

Line g has a slope of -4/7. Which of the following equations represents a line that is perpendicular to line g?
A) Y= -7/4x
B) Y= -4/7x
C) Y= 4/7x
D) Y= 7/4x
The equation that represents a line perpendicular to line g is Y= 7/4x (option D).
Explanation:A line that is perpendicular to line g will have a slope that is the negative reciprocal of -4/7. The negative reciprocal of a slope is found by flipping the fraction and changing the sign. The negative reciprocal of -4/7 is 7/4. Therefore, the equation that represents a line perpendicular to line g is Y= 7/4x (option D).

The basket of golf balls at a miniature golf course contains 18 golf balls, of which 9 are red. What is the probability that a randomly selected golf ball will be red?
Final answer:
The probability that a randomly selected golf ball will be red from a basket of 18 balls, with 9 red, is 1/2 or 50%.
Explanation:
The question is asking about the probability of selecting a red golf ball from a basket that contains 18 golf balls, with 9 of them being red. To find this probability, we divide the number of red golf balls by the total number of golf balls.
Here is the calculation:
Number of red golf balls: 9
Total number of golf balls: 18
Probability (P) of selecting a red golf ball: P = Number of red golf balls / Total number of golf balls
P = 9 / 18
P = 1/2 or 0.5 or 50%
Therefore, the probability that a randomly selected golf ball will be red is 1/2, which can also be expressed as 0.5 or 50%.

is -1/17 a repeating decimal
A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely). The repeating portion of a decimal expansion is conventionally denoted with a vinculum so, for example,
The minimum number of digits that repeats in such a number is known as the decimal period.
Repeating decimal notation was implemented in versions of the Wolfram Language prior to 6 as PeriodicForm[RealDigits[r]] after loading the add-on package NumberTheory`ContinuedFractions`.
All rational numbers have either finite decimal expansions (i.e., are regular numbers; e.g., ) or repeating decimals (e.g., ). However, irrational numbers, such as neither terminate nor become periodic.
Numbers such as 0.5 are sometimes regarded as repeating decimals since.

Mrs. smith's reading class can read a mean of 175 words per minute with a standard deviation of 20 words per minute. the top 3% of the class is to receive a special award. assuming that the distribution of words read per minute are normally distributed, what is the minimum number of words per minute a student would have to read in order to get the award?
If Mrs. smith's reading class can read a mean of 175 words per minute with a standard deviation of 20 words per minute. The top 3% of the class is to receive a special award. The minimum number of words per minute a student would have to read in order to get the award will be: 213 words per minute
Using this formula
Minimum number of words =(z score× standard deviation) + means
Where:
z score=(100%-3%=97%)
z score= 97%=1.881
Standard deviation=175
Mean=20
Let plug in the formula
Minimum number of words =(1.881×20) + 175
Minimum number of words =37.62+175
Minimum number of words =212.62
Minimum number of words =213 (Approximately)
Inconclusion if Mrs. smith's reading class can read a mean of 175 words per minute with a standard deviation of 20 words per minute. The top 3% of the class is to receive a special award. The minimum number of words per minute a student would have to read in order to get the award will be: 213 words per minute

What is 15 + 17- 100 + 1000 + (-132) x 0?
The result of the expression 15 + 17 - 100 + 1000 + (-132) x 0 is 932.
Multiplication first according to the order of operations (PEMDAS/BODMAS):
(-132) x 0 = 0
Now, substitute the result back into the equation:
15 + 17 - 100 + 1000 + 0
Next, perform the addition and subtraction from left to right:
15 + 17 = 32
32 - 100 = -68
-68 + 1000 = 932
So, the final answer is 932.
A line segment has endpoints at (–1, 4) and (4, 1). Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4)?
a reflection of the line segment across the x-axis
a reflection of the line segment across the y-axis
a reflection of the line segment across the line y = x
a reflection of the line segment across the line y = –x
Answer:
a reflection of the line segment across the line y = –x
Step-by-step explanation:
Reflecting across the line y = -x switches the x- and y-coordinates and negates both. This will map
(-1, 4)→(4, -1)→(-4, 1) and
(4, 1)→(1, 4)→(-1, -4)
The reflection that produces an image with endpoints at (–4, 1) and (–1, –4) is a reflection of the line segment across the line y = -x.
Option D is the correct answer.
What is a reflection?There are two ways of translation.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
The reflection of a point over the x-axis involves changing the sign of its
y-coordinate while leaving the x-coordinate unchanged.
The reflection of a point over the y-axis involves changing the sign of its
x-coordinate, while leaving the y-coordinate unchanged.
The reflection of a point over the line y = x involves swapping its x and y-coordinates.
The reflection of a point over the line y = -x involves swapping the sign of its x and y-coordinates.
To find the reflection that produces an image with endpoints at (–4, 1) and (–1, –4), we need to reflect the original line segment across a line that produces an image with the same length and orientation as the given endpoints.
One way to do this is to plot the points and draw the line segment, then draw the candidate lines of reflection and see which one produces the desired image.
Another way is to compute the midpoint of the original line segment and see which reflection takes that midpoint to the midpoint of the desired image.
Using the second method, the midpoint of the original line segment is:
= ((–1 + 4) / 2, (4 + 1) / 2)
= (1.5, 2.5)
The midpoint of the desired image is:
= ((–4 + –1) / 2, (1 + –4) / 2)
= (-2.5, -1.5)
To find the reflection that takes (1.5, 2.5) to (-2.5, -1.5), we can see that this is the reflection across the line y = -x.
Therefore,
The reflection that produces an image with endpoints at (–4, 1) and (–1, –4) is a reflection of the line segment across the line y = -x.

The radius of a circle is the length of the line section from the middle to some extent at the circumference of the circle. it is commonly abbreviated as 'r'. There can be countless radii drawn in a circle and the duration of all those radii can be the identical. it is half of the diameter of the circle.
Radius of a circle from region: in case you know the place A , the radius is r = √(A / π) . Radius of a circle from circumference: if you understand the circumference c , the radius is r = c / (2 * π) . Radius of a circle from diameter: if you understand the diameter d , the radius is r = d / 2
