The main span of Bridge A (2300 feet) is _____ percent shorter than the main span of Bridge B (4700 feet).
Answers
To do this you divide the difference in lengths by the starting length. We start with the main bridge.
4700-2300=2400
2400/4700 is about 51.1% shorter.
The main span of bridge A is 51.1% shorter than the main span of bridge B.
Span of bridge A = 2300 feets
Span of bridge B = 4700 feets
Percentage difference in span length :
[(difference in span) / span of B] × 100%
Difference in span = 4700 - 2300 = 2400
Percentage difference = (2400 ÷ 4700) × 100%
Percentage difference = 0.5106 × 100% = 51.1%
Therefore, the main span of bridge A is 51.1% shorter than the main span of bridge B.

Express the decimal as a percent. 0.24
Answers
Final answer:
To express the decimal 0.24 as a percent, you would multiply it by 100. The decimal 0.24 can be expressed as 24%.
Explanation:
To convert a decimal to a percent, you need to multiply it by 100. In this case, to express the decimal 0.24 as a percent, you would multiply it by 100.
0.24 * 100 = 24
So, the decimal 0.24 can be expressed as 24%.
A percent represents a part per hundred.
When you multiply a decimal such as 2.4 by 100 to find its percent equivalent, you move the decimal point two places to the right. If there are not enough decimal places, we use zeros as placeholders.
Therefore, 2.4 times 100 is 240, and 0.24 times 100 is 24, which gives us 24%.

Ron needs paper for his class project. He buys 5 packs of paper and uses all but 3 pieces. If p stands for the amount of paper per pack, which expression can he use to find out the number of papers that he used?
Answers
1 pack = p pieces of paper
5 packs = 5p pieces of paper (multiply both sides by 5)
Ron uses 5 packs, so there are 5p pieces of paper total. He uses all but 3 pieces, meaning that he uses 5p-3 pieces of paper. So that's why 5p-3 is the answer
----------------------------------------------------------
Here's a more concrete example
Let's say p = 10. In other words, let's say there are 10 pieces of paper per pack.
If that's the case, then 5 packs yield 5*10 = 50 sheets total. This is the same as saying 5p = 5*10 = 50. All I've done is replace p with 10. The letter p is simply a placeholder.
If he uses all but three sheets of paper, then Ron uses 47 sheets since 50-3 = 47. A more longer way to see this is to plug p = 10 into the expression 5p-3 and we get
5p - 3 = 5*10-3 = 50 - 3 = 47
which helps us confirm we have the right expression. I recommend you try other values of p to generate more examples. Make sure p is a whole number and that it is a positive number.
----------------------------------------------------------
Once again the answer is 5p-3
Find the general solution of the given second-order differential equation. 25y'' − 15y' − 4y = 0
Answers
Final answer:
To solve the second-order differential equation 25y'' - 15y' - 4y = 0, we find the characteristic equation and its roots, then express the general solution as a linear combination of terms with the found roots as exponents, resulting in [tex]y(t) = C_1e^{-t/5} + C_2e^{4t/5}.[/tex]
Explanation:
We are given a second-order differential equation with constant coefficients: 25y'' − 15y' − 4y = 0. First, we will look for a characteristic equation that arises from this differential equation to find the general solution.
To find the characteristic equation, we substitute [tex]y = e^{rt}[/tex] (where r is a constant) into our differential equation, replacing y'' with [tex]r^2e^{rt}[/tex], y' with [tex]re^{rt}[/tex], and y with [tex]e^{rt}[/tex]. The equation becomes 25r² − 15r − 4 = 0.
Solving for r, we find the roots of the characteristic equation, which are the values of r that satisfy the equation.
Once we have the roots, which we'll call r₁ and r₂, the general solution to the differential equation is [tex]y = C_1e^{r_1t} + C_2e^{r_2t}[/tex], where C₁ and C₂ are arbitrary constants determined by initial conditions.
To find r₁ and r₂, we factor the characteristic equation:
25r² − 15r − 4 = (5r + 1)(5r - 4) = 0. Hence, r₁ = -1/5 and r₂ = 4/5.
Finally, the general solution to the differential equation is [tex]y(t) = C_1e^{-t/5} + C_2e^{4t/5}.[/tex]
When the polynomial is written in standard form, what are the values of the leading coefficient and the constant?
5x + 2 – 3x2
Answers
First, we must define the words "leading coefficient" and "constant."
Take a look at the simple definitions...
Leading coefficient- the number behind the term with the highest exponent
Constant- the number without any variable in front of it
This means that for the polynomial
5x+2-3x^2 the leading coefficient is -3 because it is the number behind the term with the highest exponent! The constant is 2 because there are no variables behind it.
I really hope this helps!

How many triangles can be constructed with angles measuring 80 degrees 80 degrees and 40 degrees
Answers
The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.
Answer:
None
Step-by-step explanation:
The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.
80+80+40 = 200
This can't be a triangle.

On a trip, you had to change your money from dollars to British pounds. You got 560560 pounds for 800800 dollars. How many pounds will you get for 300300 dollars?
Answers
800,800÷300,300= 2.66666.... (recurring)
If $300,300 goes into $800,800 2.66666 times, then the amount of pounds you want to find goes into £560,560 2.66666 times as well. Let's write this as an equation to solve for x (where x is the amount of pounds you will obtain for $560,560):
2.66666x = 560,560
Divide both sides by 2.66666
x = 210,210
Therefore, you will get £210,210 for $300,000

According to these three facts, which statements are true?
Circle W has center (−3, 0) and radius 8.
Circle V is a translation of circle W, 2 units down.
Circle V is a dilation of circle W with a scale factor of 2.
Select each correct answer. (You can choose more than one).
A. Circle V and circle W are similar.
B. Circle V and circle W have the same center.
C. The radius of circle V is 16.
D. The center of circle V is (−5, 0).
Answers
1)Circle W has center (−3, 0) and radius 8
the equation of a circle W is
(x+3)²+(y)²=8²
2)Circle V is a translation of circle W, 2 units down.
the center of circle V--------> (-3,0-2)---------> (-3,-2)
3)Circle V is a dilation of circle W with a scale factor of 2.
then the radius circle V is 8*2------> 16 units
the equation of a circle V is
(x+3)²+(y+2)²=16²
therefore
case A. Circle V and circle W are similar.---------> is correct
because I can transform circle V to circle W using only translations, rotations and scaling (In the case of circles, no rotations are necessary).
case B. Circle V and circle W have the same center.-------> is not correct
case C. The radius of circle V is 16.-----------> is correct
case D. The center of circle V is (−5, 0).----------> is not correct
the answer is
case A. Circle V and circle W are similar.---------> is correct
case C. The radius of circle V is 16.-----------> is correct
Circle V and Circle W are similar and the radius of Circle V is 16; however, Circle V and Circle W do not have the same center, and the center of Circle V is not (-5, 0), but rather (-3, -2).
Given the information that Circle W has center (-3, 0) and radius 8, and Circle V is a translation of Circle W 2 units down and a dilation with a scale factor of 2, the following statements can be evaluated:
Circle V and Circle W are similar: This statement is true. Both circles maintain their shape after a translation and dilation.Circle V and Circle W have the same center: This statement is false. Translation moves the center of Circle V 2 units down, changing its coordinates.The radius of Circle V is 16: This statement is true. The radius is doubled through the dilation process.The center of Circle V is (-5, 0): This statement is false. The correct center after translation would be (-3, -2).At Pizza Pi, 9% of the pizzas made last week had broccoli on them. If 27 pizzas had broccoli, on how many pizzas in all were made last week?

What is the principal if the amount is $1056,the time is 4 years,and the rate is 8%?
Answers
.. I = Prt
.. 1056 = P*.08*4 . . . . . . . . substitute the given values
.. 1056/0.32 = P = 3300 . . divide by the coefficient of P and evaluate
The principal is $3300.
The principal amount is calculated using the formula for simple interest. By rearranging the formula and inputting the given values for the amount, time, and interest rate, the principal is determined to be $800.
To find the principal if the amount is $1056, the time is 4 years, and the rate is 8%, we can use the formula for simple interest which is:
Amount = Principal + (Principal × Rate × Time)
Rewriting the formula to solve for principal (P), we get:
Principal = Amount ÷ (1 + Rate × Time)
Substituting the given values:
Principal = $1056 ÷ (1 + 0.08 × 4)
Principal = $1056 ÷ (1 + 0.32)
Principal = $1056 ÷ 1.32
Principal = $800
Therefore, the principal is $800.
