Answer:
31.702 inches (C)
Step-by-step explanation:
Here we need to calculate the circumference of the bike tire.
The formula for Circumference is C = πd, where d is the diameter.
Here, C = π(26 in), or 26π in. Every time the wheel rotates, the bike covers 26π in. If one tire completed 388 full rotations, then the distance Marc traveled was (26π inches/rotation)(388 rotations), or, to the nearest inch,
31,692 inches. This corresponds to (C) of the given possible answer choices.

HELP ASFAST AS POSSIBLE. What ratio is equivalent to 40%.
A. 1 to 4
B. 4 to 1
C. 2 to 5
D. 5 to 2
Divide the first number by the second number for each ratio:
A. 1 to 4 = 1/4 = 0.25 = 25%
B. 4 to 1 = 4/1 = 4 = 400%
C. 2 to 5 = 2/5 = 0.4 = 40%
The answer is C.
An equivalent ratio to 40% is 2 to 5, which is option C. The percentage is simplified by dividing it by the greatest common divisor to find its simplest ratio form.
Explanation:To find a ratio equivalent to 40%, we first understand that percentages are a way of expressing a ratio where the second term is 100. Therefore, 40% is the same as saying 40 out of 100 or 40/100.
Next, we simplify this fraction to its lowest terms. Dividing both numerator and denominator by their greatest common divisor, which is 20 in this case, gives us 2/5. Thus, the ratio equivalent to 40% in its simplest form is 2 to 5, which corresponds to option C.
If we were to check the other options given, A (1 to 4) and B (4 to 1) are equivalent to 25% and 400% respectively, while D (5 to 2) is equivalent to 250%. Hence, these are not correct.
To illustrate the concept, let's consider an example. If the scale dimension is 4 cm, then to find the actual dimension using the proportion 1:2=4:x, we would cross-multiply to find x, which would be 8 cm, showing how ratios can be used to find corresponding values.

Elyse is going to buy an around-the-world plane ticket. She will get to see just one city from each continent she will visit. The following table below shows the continents on her trip and how many cities she can choose from for each continent. Continent Number of cities Europe 10 Asia 888 Africa 4 Australia 3 How many different combinations of cities does Elyse have to choose from?
Answer:
960
Step-by-step explanation:
10 x 8 x 4 x 3
Hope This Helped
Regards Jaygtgajm11
Disclaimer: The number of cities in Asia will be 8 and not 888.
Elyse can choose from 960 different combinations of cities.
What are permutations and combinations?The different ways in which objects from a set can be picked, often without replacement, to produce subsets are known as permutations and combinations. When the order of selection is a factor, this selection of subsets is termed a permutation; when order is not a factor, it is called a combination.
How do we solve the given question?We are given 4 continents, with a number of cities to choose from for Elyse to visit.
The table is like this:
Continent Number of cities
Europe 10
Asia 8
Africa 4
Australia 3
We use permutations and combinations to find the number of combinations Elyse will have to choose from.
We can say that for every 10 cities in Europe, she can choose any of the 8 cities in Asia. Similarly, for every 8 cities in Asia, she can choose any of the 4 cities in Africa. And similar is the case for Africa and Australia.
∴ Elyse can choose from a combination of 10*8*4*3 cities,
or, Elyse can choose from a combination of 960 cities.

A height is labeled on the triangle below. Which line segment shows the base that corresponds to the given height of the triangle?
Answer:
Option A
Step-by-step explanation:
We are given that a height is labeled on the triangle in given figure.
We have to find the that segment which shows the base that correspond to the given height of the triangle
We know that base is that side of triangle on which height is perpendicular.
In the given figure, Height is perpendicular to side A.
Therefore, side A represent the base of triangle.

The combined area of the 3 windowpanes and frame shown below is 924 inches squared. The frame is of uniform width. What is the side length, x, of each square windowpane?
Answer:
The sides length x of each square windowpane is [tex]10\ in[/tex]
Step-by-step explanation:
we know that
[tex]924\ in^{2}=(6+3x+6)(6+x+6)\\ \\924=(12+3x)(12+x)\\ \\924=144+12x+36x+3x^{2}\\ \\ 3x^{2}+48x- 780=0[/tex]
Solve the quadratic equation
using a graphing tool
The solution is [tex]x=10\ in[/tex]
see the attached figure
Answer:
10 inches is the side length of each square windowpane.
Step-by-step explanation:
Length of the single window plane = x
Width of the single window plane = x
On combining all the windows pane ,length becomes , l= 3x
On combining all the windows pane ,width becomes , b= x
Length of the frame = L = 6 + 3x+ 6 = 12 + 3x
Width of the frame = B = 6 + x+ 6 = 12 + x
Area of the frame, A = L × B = [tex](12+3x)\times (12+x)[/tex]
Given sum of combined area of the 3 windowpanes and frame = [tex]924 inch^2[/tex]
[tex]a + A=924[/tex]
[tex](12+3x)\times (12+x)=924[/tex]
[tex]144+48x+3x^2=924[/tex]
[tex]3x^2+48x-780=[/tex]

Explain why the square root64 has a positive and negative value
Answer:
Because when you square 8 or -8, you will still end up at 64
8 x 8 = 64
(-8) x (-8) = 64
Step-by-step explanation:
Ok so the square root of 64 is both positive and negative 8 because :
8^2= 64 but at the same time:
(-8)^2=64 because - to the power of two becomes positive so it has two answers because both 8 and -8 to the power of 2 is 64

what method would you choose to solve the equation 2x^2-7=9? explain why you chose this method.
Answer:
2.87
Step-by-step explanation:
2x^2-7=9
2x^2=9+7
2x^2/2=16/2
(square root)x^2=(square root)8
x=2.87
I used this method because I don't know any other method.
Answer:
Sample Response: I would use the square root property of equality. Because there is no x term, I would just add and divide to get x^2 by itself. Then I would take the square root.
2x^2 - 7 = 9
2x^2 - 7 + 7 = 9 + 7
2x^2 = 16
2x^2/2 = 16/2
x^2 = 8 (square root of 8 would be square root of 4*2 = 2*square root of 2
x = +/- 2*square root of 2

Answer:
[tex]h=(x^{4}+4x^{3}+8x+4)/(x^{3}+3x^{2}+8)[/tex]
Step-by-step explanation:
Let
h------> the height of the prism
we know that
The volume of the prism is equal to
[tex]V=Bh[/tex]
where
B is the area of the base
h is the height of the prism
In this problem we have

[tex]B=x^{3}+3x^{2}+8[/tex]
substitute and solve for h
[tex]x^{4}+4x^{3}+8x+4=(x^{3}+3x^{2}+8)h[/tex]
[tex]h=(x^{4}+4x^{3}+8x+4)/(x^{3}+3x^{2}+8)[/tex]

An element has half life of about 20 days. How much of 3000 gram sample is left after 100 days?
t=100
p=3000
t 1/2 = 20
Try inserting the numbers in the half-life formula.
Answer:
93.75 gm.
Step-by-step explanation:
We have been given that an element has half life of about 20 days. We are asked to find the amount of 3000 gm sample left after 100 days.
We will use half-life formula to solve our given problem.
[tex]A=a\cdot (\frac{1}{2})^{\frac{t}{h}}[/tex], where,
A = Amount left after t units of time,
t = Time,
a = Initial amount,
h = Half-life.
Upon substituting our given values in above formula, we will get:
[tex]A=3000\cdot (\frac{1}{2})^{\frac{100}{20}}[/tex]
[tex]A=3000\cdot (0.5)^{5}[/tex]
[tex]A=3000\cdot 0.03125[/tex]
[tex]A=93.75[/tex]
Therefore, 93.75 gm of sample is left after 100 days.

Tim needs 3 pounds of vegetables for a vegetable soup recipe.
He already has 2/3 pound of carrots and 1/4 pound of celery.
Drag the vegetables Tim can add to what he already has to make exactly 3 pounds of vegetables.
Answer:
25/12 - pounds more vegetables
Step-by-step explanation:
first we need to put these variables into like terms
36/12 - 3
8/12 - 2/3
3/12 - 1/4
add the last two up and subtract from the first and you get how much you need left over
Tim already has 11/12 pounds of vegetables. He requires Problem Solving for an additional 2 1/12 pounds of vegetables to reach the desired 3 pounds for his soup recipe. Therefore, option B is the correct answer.
The problem is asking about the amount of vegetables Tim needs to add to reach a total of 3 pounds for his soup. Given, he already has 2/3 pound of carrots and 1/4 pound of celery, he already has a combined total of 2/3 + 1/4 = 11/12 pounds of vegetables.
Now, we need to find out how many more pounds of vegetables he needs to reach 3 pounds. To do this, subtract the weight of the vegetables he has from the total weight required: 3 pounds - 11/12 pounds = 25/12 or 2 1/12 pounds.
So, Tim needs to add an additional 2 1/12 pounds of vegetables for his soup. Looking at the options given, Tim should choose option B) 1 1/12 pounds of zucchini.
