3/10
The probability of choosing the letter 't' will be 3 / 10.
What is probability?
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:-
If one letter is chosen at random from the word substitute.what is the probability that the letter chosen will be a "t"?The probability will be calculated as:-
There are 10 letters in the word SUBSTITUTE.
Out of these 10 letters, t is three times in the word
So probability will be:-
P = 3 / 10
Therefore the probability of choosing the letter 't' will be 3 / 10.

Step-by-step explanation:
You take out a loan for $523 at an interest rate of 9% for five years. What is the total amount
that you will have at the end of the five years?
Final answer:
To find the total amount due after five years on a loan of $523 with a 9% interest rate, first calculate the simple interest ($235.35) and then add it to the principal to get a total of $758.35.
Explanation:
To calculate the total amount you will have at the end of five years after taking out a loan for $523 at an interest rate of 9%, you need to use the formula for calculating the future value with simple interest: Principal + (principal × rate × time). The principal in this case is $523, the rate is 0.09 (9% expressed as a decimal), and the time is 5 years.
First, we calculate the simple interest: Interest = Principal × rate × time = $523 × 0.09 × 5. This gives us the total interest that will be charged over the five years.
Step 2. Calculate the simple interest: $523 × 0.09 × 5 = $235.35.
Step 3. Calculate the total future amount using the formula: Principal + Interest = $523 + $235.35 = $758.35.
Therefore, the total amount that you will have to pay at the end of the five years is $758.35.

The expression 4^{3}+8-\dfrac{9}{y4} can be broken down into different components:
1. 4^{3}: This part represents 4 cubed, which is equal to 4 x 4 x 4 = 64.
2. +8: This is simply the addition of 8 to the previous result, which is 64 + 8 = 72.
3. -\dfrac{9}{y4}:
Here, we have a subtraction and a fraction.
It's important to note that there might be a typo in the expression, and it should perhaps be written as \(\dfrac{9}{y}4\), which would mean 9 divided by y and then multiplied by 4.
If that's the case, the result depends on the value of y.
The expression demonstrates the use of exponentiation, addition, subtraction, and fractions, making it a comprehensive example of various mathematical operations.
In summary, the expression 4^{3}+8-\dfrac{9}{y4} showcases the use of exponentiation, addition, and subtraction, along with a fraction.
It's important to clarify whether the fraction should be interpreted as \(\dfrac{9}{y}4\) or \(\dfrac{9}{y4}\) to determine its exact mathematical meaning and result.

Identify given.
[Ralph's Walking Distance Function]: d = -6t + 10
[Joan's Bicycle Distance Function]: d = 14t
Step 2: Find Meeting Point
To find where Joan and Ralph will meet, we need to find where they intersect. Therefore, we need to find the time which they both meet up at. To do this, we can use the process of substitution to find our value of t:
[Equation 1] Substitute in d:From here, we can simply use techniques listed under "Algebra I" to solve for t:

Topic: Algebra I
The answer is B. 7 miles. Joan and Ralph meet when their distances are equal. By solving the distance equations, we find they meet after 7 miles.
To establish where Joan will meet Ralph, we must find the time when their distances are equal. We equate their distance equations: d = -6t + 10 (Ralph) and d = 14t (Joan).
Set the equations equal to each other:
-6t + 10 = 14tCombine like terms:
10 = 14t + 6t10 = 20tDivide both sides by 20:
t = 0.5Next, we substitute t = 0.5 into either of the original equations to find the distance:
Using Joan's equation: d = 14t
d = 14(0.5)d = 7So, the distance at which Joan meets Ralph is 7 miles.
Therefore, the correct answer is B. 7 miles.

Answer:
75 men spent 7 hours or more exercising.
Step-by-step explanation:
If you multiply 300 by 0.67, you get 201. That would be the amount of men. Multiply 300 by 0.37 to get 111, the amount of people who spent less than 7 hours exercising, and subtract it from the 201 men to get 90. Then, multiply 300 by 0.75 to get 225, the amount of women that spent 7 hours or more exercising, and subtract it from 300, which would result in an answer of 75. That's how many men spent 7 hours or more exercising.

There are 90 picking days in a season. A farms picks approximately 8 x 104 papayas
each day. Approximately, how many papayas are picked each season?
Answer:
74880
Step-by-step explanation:
first you do 8x104 and get 832 and then you do 832x90 and you get 74880.
By performing multiplication, you find that a farm picking approximately 800,000 papayas each day for 90 days in a season would pick around 72,000,000 papayas in total.
Explanation:The subject of this question is Mathematics, specifically multiplication. To determine the total number of papayas picked in a season, we can multiply the number of picking days in a season by the average number of papayas picked each day. Thus, we need to multiply 90 (the number of picking days in a season) by 8 x 104 (the average number of papayas picked each day). Step-by-step, this process would look like the following:
Convert 8 x 104 to its standard form, which is 800,000. This represents the number of papayas picked each day. Multiply 800,000 papayas by 90 days. 800,000 papayas/day * 90 days = 72,000,000 papayas.
Therefore, the farm picks approximately 72,000,000 papayas in a season.

Data Presentation - Tables
Tables are a useful way to organize information using rows and columns. Tables are a versatile organization tool and can be used to communicate information on their own, or they can be used to accompany another data representation type (like a graph). Tables support a variety of parameters and can be used to keep track of frequencies, variable associations, and more.
For example, given below are the weights of 20 students in grade 10:
50, 45, 48, 39, 40, 48, 54, 50, 48, 48, \\ 50, 39, 41, 46, 44, 43, 54, 57, 60, 45.

50,39,41,46,44,43,54,57,60,45.
To find the frequency of 4848 in this data, count the number of times that 4848 appears in the list. There are 44 students that have this weight.
The list above has information about the weight of 2020 students, and since the data has been arranged haphazardly, it is difficult to classify the students properly.
To make the information more clear, tabulate the given data.

Drag point P around the unit circle to find the values of the trigonometric functions.
sin(90°) = 1
cos(180°) = -1
sin(40°) = .643
cos(245°) = -.423
Answer:
See the attachment
Step-by-step explanation:
A unit circle is one whose radius is 1
sin(90) will have coordinates (0,1)
sin(40)= 0.643
sin(40)= P/H= 0.643/1
cos(40)= B/H= 0.766
Similarly for cos(245)= cos(-65)= -0.423/1
sin(245)= sin(-65)= -0.906
The question involves applying knowledge of the unit circle and trigonometric identities to find the values of sine and cosine for certain angles as well as using the Law of Sines and Law of Cosines in triangle problems.
The question involves finding trigonometric function values using the unit circle. The unit circle is a circle with a radius of 1 unit, centered at the origin of the coordinate system, and is a fundamental tool in trigonometry. The sine and cosine values for certain angles are as follows:
sin(90°) = 1
cos(180°) = -1
sin(40°) = 0.643
cos(245°) = -0.423
Additionally, trigonometric identities like sin(90° – x) = cos x are useful for finding values of sine and cosine for complementary angles. The Law of Sines and the Law of Cosines can help solve for unknowns in triangles when certain side lengths and angles are known.
How many 8-inch square tiles are needed to cover a rectangle floor that is 10 ft. long and 8 ft. wide?
A. 80
B. 10
C. 180
D. 160
Answer:
180 tiles
Step-by-step explanation:
It's easiest to work with only one unit for length and one unit for area. We will work with inches and square inches, and we will convert feet to inches.
An 8-inch square tile is a tile shaped like a square whose side measures 8 inches.
area of square = side^2
area of 1 tile = (8 in.)^2 = 64 in.^2
One 8-inch, square tile has an area of 64 sq in.
Now we need to find the area of the floor in square inches.
1 ft = 12 in.
We multiply each dimension in ft by 12 to find inches.
10 ft = 10 * 12 in. = 120 in.
8 ft = 8 * 12 in. = 96 in.
Now we find the area of the rectangular floor.
area of rectangle = length * width
area of rectangle = 120 in. * 96 in.
area of rectangle = 11,520 sq in.
The rectangular floor has an area of 11,520 sq in.
Each tile has an area of 64 sq in.
To see how many tiles are needed, we divide the area of the floor by the area of one tile.
number of tiles = (11,520 sq in.)/(64 sq in.) = 180
Answer: 180 tiles
