A pattern follows the rule "Start at 3 and add 10."
Which statement is true about the pattern?
A: Each term is 13 more than the previous term because the tens digit goes up by 1 and the one's digit goes up by 3.
B: Each term is 10 times the previous term because the tens digit goes up by 1 and the ones digit stays the same.
C: For each term, the ones digit stays the same and the tens digit goes up by 1 because 10 has one ten and no ones.
D: For each term, the ones digit goes up by 3 and the tens digit goes up by 1 because you start at 3 and go up by 10 each time.
B: Each term is 10 times the previous term because the tens digit goes up by 1 and the ones digit stays the same.
Find the lateral area and the surface area of the composite solid. Round your answers to the nearest hundredth.
The lateral area is about ____
square inches
The surface area is about ___
square inches
The surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.
What is the area?The space occupied by any figure in the two-dimensional space is called an area. The area can be rectangular circular triangular types.
Here we have the figure made up by the two pyramids and one rectangular box. So we will find the surface area of the pyramid then the rectangular box and again the pyramid and will add all of them.
The Lateral surface area will be calculated as:-
A=2W√(w÷2)²+(h)²+w²
A=2x5√(5÷2)²+(3)²+5x5
A=152.5 +25
A=177.5 square inch
Area of lower pyramid= (1÷2)xbxh+w²
A=(1÷2)x5x7.5 + 25 =75+25= 100
Area of the rectangular box= 4(w²)=4(5x5)=100
So total lateral surface area will be =100+100+177.5=377.5 square inch
(2)The surface area will be calculated as:-
A=2W√(w÷2)²+(h)²
A=2x5√(5÷2)²+(3)²
A=152.5 square inches
Area of lower pyramid= (1÷2)xbxh
A=(1÷2)x5x7.5 =75 square inches
Area of the rectangular box= 4(w²)=4(5x5)=100
So total surface area will be =100+75+152.5=327.5 square inch
Hence the surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.

Ravi buys lunch at a restaurant.
An 8% sales tax is added, and he tips the waiter 20% of the cost of the food.
Ravi pays a total of $17.92 for his lunch, including tax and tip.
What is the price of Ravi's lunch, before tax and tip?
The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.
What is the price of the lunch?Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.
Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34
Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19

How many square inches of fabric does Kendall need for a triangle flag with a base of 20 inches a height of 40 inches
Answer: [tex]400^{2}[/tex]
Step-by-step explanation:
First, write the formula:
A = (b × h) / 2
Next, multiply the base and the height of the triangle.
20 x 40 = 800
Finally, divide 800 by 2.
800/2=400
Therefore, the answer is [tex]400^{2}[/tex].
The rate startfraction 450 pounds over 25 buckets endfraction describes the relationship between the number of buckets and the weight of the lobsters in the buckets. what is the weight of one bucket of lobsters?
15 pounds per bucket
18 pounds per bucket
20 pounds per bucket
25 pounds per bucket
Answer:
The answer is 18 pounds per bucket.
Understanding the ProblemIn this question, we are given the expression that relates the pounds of lobster to the number of buckets:
[tex]\displaystyle \frac{\text{450 pounds}}{\text{25 buckets}}[/tex]
This fraction is presented to give a proportion of pounds of lobster to the number of buckets these lobsters inhabit.
With this proportion, we are expected to assume that the rate will be equivalent across all of the buckets. Therefore, for each bucket, there will be an equal measurement of pounds of lobster.How to Solve the ProblemTo solve this problem, we need to know exactly how this rate will work.
A rate is the same thing as a fraction, percentage, or decimal. All of these forms are convertible between one another.
For instance, if we took 25%, we know that by dividing this by 100, we receive a decimal form (0.25) or a fractional form (1/4).
We can apply the same principle here.
SolvePart I - Set up the Rate
To solve, set up the rate:
[tex]\displaystyle \frac{450 \ \text{pounds}}{25 \ \text{buckets}}[/tex]
Part II - Find the GCF
Then, find the Greatest Common Factor (GCF) of the two digits:
25 — 1, 5, 25450 — 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450Check for common factors between the two trees:
1, 5, 25Since 25 is the greatest of the three factors, it is the GCF.
Part III - Apply the GCF
Divide both the numerator and the denominator by 25:
[tex]\displaystyle \frac{450}{25} = 18[/tex]
[tex]\displaystyle \frac{25}{25} = 1[/tex]
Part IV - Simplify
Set up the new fraction:
[tex]\displaystyle \frac{18}{1}[/tex]
Anything divided by 1 does not change:
[tex]\displaystyle \frac{18}{1} = 18[/tex]
Final ApplicationsSince we got 18 an answer, this means that there are 18 pounds of lobster per bucket.
Colleen has put $26,000 into a retirement fund. the fund has an estimated annual return of 10%. if colleen doesn't add any more money, how much can she expect to have in the fund in 7 years?
if necessary, round your answer to the nearest cent
the answer is : 50,666.64
Using an exponential function, it is found that she can be expected to have $50,666.64 in the fund in 7 years.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, we have that the initial amount and the growth rate are given, respectively, by:
A(0) = 26000.r = 0.1.Hence the amount after t years is given by:
[tex]A(t) = 26000(1.1)^t[/tex]
Then, after 7 years, the amount is:
[tex]A(7) = 26000(1.1)^7 = 50,666.64[/tex]

What does it mean for data to have variability as it refers to statistical questions? Give an example
Answer:
The term, "variability" describes how far apart data points lie from each other, and from the center of a distribution.
Along with measures of central tendency, measures of variability give you descriptive statistics that summarize your data.
Variability is also referred to as spread, scatter or dispersion.

Step-by-step explanation:
Hey there!
In order to find the area of this triangle, we need to find the base and height of the triangle
the base of the triangle is 7 units long and the height of the triangle is 4 units high
Formula for area of triangle: Base x Height x 1/2
7 x 4 x 1/2 --> 28 x 1/2 --> 14
So, the area of this triangle is 14
Now the question is asking to find the area by forming a parallelogram
All you have to do for this is duplicate that same triangle, and mirror it upside down
Then all you would have to do is find the Base and the Height and multiply them together

QR is the radius of R and PQ is the tangent to R. Find the value of x.
Answer:
x = 39
Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:
80^2 + x^2 = 89^2
6400 +x^2 = 7921
x^2 = 1521
x = [tex]\sqrt{1521}[/tex]
x = 39
