The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³

Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3
There are 550 people at the school carnival.
Part A
If 385 of the people are students, what percentage of the people at the carnival are students?
Part B:
If 30% of all the people at the carnival are on a ride, how many people are on the ride?
Answer:
70% of the people at the fair are students
165 people are on the ride
Step-by-step explanation:
In order to find a percentage, take the fraction given, 385/550, and divide the numerator, 385, and divide it by the denominator, 550. Once completing this, we get 0.7
Next, we multiply the result by 100, and get 70, thus, 385 is 70% of 550.
To find how many people 30% of 550 is, we take the percentage and put it in a fraction with the denominator being 100(changes with size of fraction like a decimal, 300 would be over a denominator of 1000)
With 30/100, we then multiply by 550 with the equation looking like this:
30/100*550/1
Once we finish multiplying(typically using a calculator, although you can do it manually) we get 165, the value of how many people are on rides out of the total 550.
While parasailing. Ryan spots a dolphin on the water below. If Ryan is 228 feet above the
water and the angle of depression to the dolphin is 15, what is the horizontal distance
between Ryan and the dolphin?
Answer:
850.9 feet
Step-by-step explanation:
The horizontal distance between Ryan and the dolphin is 850.907 feet.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.
Using trigonometry
tan 15 = 228/ x
x= 228/ tan 15
x= 228 / 0.26794919243
x = 850.907 feet

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
What domain makes sense for the function in this context?
A. all positive numbers
B. 0 ≤ t ≤ 5
C. all real numbers
D. 0 ≤ t ≤ 100
Answer:
B. 0 ≤ t ≤ 5Step-by-step explanation:
The function is g(t) = -16t² + vt + h
At h = 0 and v = 80 we get the function:
g(t) = -16t² + 80tWe know g(t) can't be negative, then:
-16t² + 80t ≥0t² - 5t ≤ 0t(t - 5) ≤ 5t ≥0 and t ≤ 5, or0 ≤ t ≤ 5Correct option is B

23=Prime
Hello there!
Prime numbers have 2 factors and composite numbers have 3 or more factors.
17 is prime because it has only 2 factors: 1 and itself.
54 is composite because it has more than 3 factors.
77 is composite because it has more than 3 factors.
23 is prime because it has only 2 factors.

What is the area, in square meters, of the figure below?
Answer:
[tex]0.55[/tex] square meters
Step-by-step explanation:
The area of a triangle can be calculated by multiplying its height and base, then dividing the result by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] is the base and [tex]h[/tex] is the height. In this case, [tex]b=2.2[/tex] and [tex]h=0.5[/tex]. Therefore, the area of the triangle is:
[tex]\frac{bh}{2}\\= \frac{2.2*0.5}{2}\\=\frac{1.1}{2} \\= 0.55[/tex]
Hope this helps!
By observing the diagram, we have :
Base of triangle, b = 2.2 mHeight of triangle, h = 0.5 mNow, we know that :
[tex] \large \underline{\boxed{\tt{Area_{(triangle)} = \dfrac{1}{2} \times base \times height}}}[/tex]
So, by substituting values, Area of given triangle will be :
[tex] \sf : \implies Area = \dfrac{1}{2} \times 2.2\: m \times 0.5\: m[/tex]
[tex] \sf : \implies Area = \dfrac{1}{\cancel{2}} \times \dfrac{\cancel{22}}{10} \: m \times \dfrac{5}{10} \: m[/tex]
[tex] \sf : \implies Area = 1 \times \dfrac{11}{10} \: m \times \dfrac{5}{10}\: m[/tex]
[tex] \sf : \implies Area = \dfrac{55}{100} \: m^{2}[/tex]
[tex] \sf : \implies Area = 0.55 \: m^{2}[/tex]
Hence, Area of given triangle is 0.55 m².
