1. There are three buses A, B and C. the total
number of seats in the three buses is 250. 28% of
the 250 seat are in bus A.
number of seats in bus B:number of seats in bus
C = 3:2
38 of the seats in bus B are empty. 26 in bus C
are empty.
Jamie says the percentage of the seats in bus B
that are empty is greater than the percentage of
the seats in bus C that are empty. Is Jamie
correct.
Thus, Jamie is wrong. In contrast to Bus C, Bus B has less unoccupied seats as a percentage of total seats.
How do the percentages translate?% is a relative number that is used to represent hundredths of the any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage.
Find the complete seating capacity in Bus A first:
Bus A has 28% of the available seats, making its seat count 0.28 x 250 = 70.
Secondly, we can construct an equation system using the number of seats in Bus B compared to Bus C:
The number of seats aboard Bus B will be x.
In that case, Bus C's seating capacity is (2/3)x.
Using the information that there are 250 seats overall, we can find x:
70 (from Bus A) + x (from Bus B) + (2/3)x (from Bus C) = 250
When we simplify this equation, we obtain: (5/3)x = 180
When we solve for x, we get x = 108.
Bus C has (2/3)x = 72 seats, but Bus B has 108 seats.
We can now determine the proportion of vacant seats for each bus:
Out of a total of 108 seats, 38 seats on Bus B are vacant, making the percentage of vacant seats in Bus B (38/108) x 100% = 35.19%.
Out of a total of 72 seats, there are 26 empty seats on Bus C, making the percentage for empty seats there (26/72) x 100% = 36.11%.

Marrero measured the radius of the sector to be 9 ft, and the radius of the circle to be 1. 5 ft. At the end, he found out that the angle of the sector is 24°. What is the total area of the exclamation point on this Little Havana billboard? Round to the nearest square foot
The overall area of the exclamation point at the Little Havana billboard is about 24 square ft while rounded to the nearest square foot.
To discover the total area of the exclamation point, we need to calculate the area of the sector and the area of the circle, after which add them collectively.
First, let's find the area of the sector. The formula for the area of a circle area is:
Area of sector = (angle/360) x π x radius^2
Substituting the given values, we get:
Area of sector = [tex](24/360) x π x 9^2 = 16.62 ft²[/tex]
Next, let's find the area of the circle. The components for the area of a circle is:
Area of circle = π x radius^2
Substituting the given value, we get:
Area of circle [tex]= π x 1.5^2 = 7.07 ft²[/tex]
Now, we are able to add the areas of the sector and the circle to get the whole area of the exclamation point:
[tex]6.62 feet² + 7.07 feet² = 23.69 ft²[/tex]
Therefore, the overall area of the exclamation point at the Little Havana billboard is about 24 square ft while rounded to the nearest square foot.

How to find the perimeter of a triangle?The perimeter of a triangle is the sum of the whole three sides of the triangle. The triangle above is an equilateral triangle.
An equilateral triangle has all it sides and angles congruent to each other.
Therefore, the perimeter of the triangle can be found as follows:
Let's find the side of the triangle using trigonometric ratios,
sin 60 = opposite / hypotenuse
sin 60 = 4√15 / h
cross multiply
h = 4√15 ÷ √3 / 2
h = 4√15 × 2 / √3
h = 8√15 / √3
Hence,
hypotenuse side = 8√45 / 3
perimeter of the triangle = 8√45 / 3 + 8√45 / 3 + 8√45 / 3
perimeter of the triangle = 8√45 + 8√45 + 8√45 / 3

how much pure alcohol must a pharmacist add to 10cm^3 of an 8% alcohol solution to strengthen it to an 80% solution
[tex]36 cm^3[/tex] of pure alcoh ol must be added to the [tex]10 cm^3[/tex] of the 8% solution to obtain [tex]10 + 36 = 46 cm^3[/tex] of an 80% solution.
What is Algebraic expression ?
Algebraic expression can be defined as combination οf variables and constants
Let's first calculate the amount of pure alcohol in the 8% solution:
Amount of pure alcohol = 8% of [tex]10 cm^3 = 0.08 x 10 cm^3 = 0.8 cm^3[/tex]
N ow, let's assume [tex]x cm^3[/tex]of pure alcohol must be added to the 10 cm^3 of the 8% solution to obtain a total volume of [tex]10 + x cm^3[/tex] of an 80% solution. The amount of pure alcohol in the final solution would be:
ο[tex](10 + x) cm^3 = 0.8 (10 + x) cm^3[/tex]
Since we started with [tex]0.8 cm^3[/tex]of pure alcohol and we want to end up with
[tex]0.8 (10 + x) cm^3[/tex], we can set up the following equation:
[tex]0.8 + x = 0.8 (10 + x)[/tex]ο
Simplifying and solving for x, we get:
[tex]0.8 + x = 8 + 0.8x[/tex]
[tex]0.2x = 7.2[/tex]
[tex]x = 36[/tex]
Therefore, [tex]36 cm^3[/tex] of pure alcohol must be added to the [tex]10 cm^3[/tex]of the 8% solution to obtain [tex]10 + 36 = 46 cm^3[/tex] of an 80% solution.

use half angle or power reduction formulas to fill in the blanks for the following identity:
Using power reduction formula and half angle formula, the blanks are "-1/2cos(x)" and "2x", respectively.
What are the missing values in the identity?We can use the power reduction formula for sine to express sin(3x) in terms of cosines:
sin(3x) = 3sin(x) - 4sin³(x)
= 3(1 - cos²(x)) - 4(1 - cos²(x))sin²(x)
= 3cos²(x) - 4cos⁴(x) - 4sin²(x)cos²(x)
= 3cos²(x) - 4cos⁴(x) - 2sin²(2x)
Now we can substitute this expression into the left-hand side of the identity and simplify using the half angle formula for cosine:
(sin(3x))⁴ = (3cos²(x) - 4cos⁴(x) - 2sin²(2x))⁴
= (3cos²(x) - 4cos⁴(x) - (1 - cos(4x)))⁴
= (3cos²(x) - 4cos⁴(x) - 1 + cos(4x))⁴
= (cos(4x) - 4cos⁴(x) + 3cos²(x) - 1)⁴
Now we can use the half angle formula for cosine again to express cos(4x) in terms of cosines of multiples of x:
cos(4x) = 2cos²(2x) - 1
= 2(2cos²(x) - 1)² - 1
= 8cos⁴(x) - 8cos²(x) + 1
Substituting this expression back into the above identity, we get:
(sin(3x))⁴ = (8cos⁴(x) - 8cos²(x) + 3cos²(x) - 4cos⁴(x) - 1)⁴
= (4cos⁴(x) - 5cos²(x) - 1)⁴
= (-1/2cos(x) + 1/8cos(2x))⁴
Therefore, the blanks in the original identity can be filled with "-1/2cos(x)" and "2x", respectively.

The divisiοn's final value is the leftοver amοunt. The Remainder Theοrem states that this number is equal tο P(-1), which is what we were lοοking fοr. Hence, P(-1) equals 1.
Hence, using synthetic divisiοn and the Remainder Theοrem, we have established that P(-1) = -1.

What is synthetic divisiοn?Synthetic divisiοn is a shοrthand methοd οf dividing a pοlynοmial by a linear factοr οf the fοrm (x - c), where c is a cοnstant. It is a methοd οf pοlynοmial lοng divisiοn that simplifies the prοcess and reduces the number οf steps required.
Tο evaluate P(-1) using synthetic divisiοn and the Remainder Theοrem, we can fοllοw these steps:
Step 1: Write the cοefficients οf the pοlynοmial P(x) in οrder οf decreasing degree, including any missing terms with a cοefficient οf 0. In this case,
[tex]P(x) = 3x^2 + 10x + 1[/tex]
Step 2: Set up the synthetic divisiοn table by placing the value οf c, which is -1 in this case, in the leftmοst cοlumn and writing the cοefficients οf the pοlynοmial in the secοnd cοlumn:
-1 | 3 10 1
Step 3: Bring dοwn the first cοefficient, which is 3, intο the third cοlumn:
-1 | 3 10 1
---------
3
Step 4: Multiply the value in the third cοlumn by the value οf c, which is -1, and write the result in the fοurth cοlumn:
-1 | 3 10 1
---------
3 -3
Step 5: Add the values in the secοnd and fοurth cοlumns and write the result in the fifth cοlumn:
-1 | 3 10 1
---------
3 -3 0
Step 6: The value in the last cοlumn, 0, is the remainder when P(x) is divided by x + c, which is x + 1 in this case. Therefοre, we can use the Remainder Theοrem tο cοnclude that P(-1) = 0.
Thus, [tex]P(-1) = 3(-1)^2 + 10(-1) + 1 = 3 - 10 + 1 = -6.[/tex]

The measure for angle I is 112.5 degrees
How to solve for angle HThe question tells us that ∠F must be 67.5°
from the sign, the angles H and the angle F are vertical angles.
Hence the value of ∠F = ∠H
∠H = 67.5°
what is the measure of angle i ?From the transversal, we can see that the angle E and angle I are corresponding angles
to get angle E
= 67.5° + ∠E = 180 (angles on a straight line)
∠E = 180 - 67.5
∠E = 112.5 degrees
Since ∠E and ∠I are corresponding angles, ∠I = 112.5 degrees

The graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.
What is a function?
It is defined as a special type of relationship and they have a predefined domain and range according to the function.
We have a function:
y= x²(x² - 6x + 9)
We can write it as a:
y=x²(x-3)²
To find the zeros equate to the function with the zero.
y = 0
x²(x-3)² =0
First, take x²=0 we get:
x = 0
Now
(x - 3)² =0
x - 3 = 0
x = 3
Thus, the graph of the function has zeros of 0 and 3, two distinct real zeros, and no complex zeros.

Edmund had $140. He spent 3 7 of his money on toys and 1 5 of his money on new clothes. How much money did Edmund spend altogether?
Edmund spent $63.50 on toys and $28 on new clothes, for a total cost of $91.50.
Edmund had $140 and he decided to spend some of that money on toys and some on new clothes. To calculate how much he spent altogether, we need to first figure out how much he spent on each item. For toys, he spent 3/7 of his total money, which is equal to $63.50. For new clothes, he spent 1/5 of his total money, which is equal to $28. Now that we know how much he spent on each item, we can add these two numbers together to figure out how much he spent altogether. When we add $63.50 and $28, we get a total of $91.50. This means that Edmund spent $91.50 on toys and new clothes altogether.
