Answer:
Number of 7th grade = 360 - X
Step-by-step explanation:
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from &th grade. As we know: Total number of students on the A honor roll = 360 We are asked to calculate, number of students from 7th grade on the A honor roll. So, let's assume that "X" represents the all the students who are on the A honor roll except 7th grade. Mathematical Expression: Number of 7th Graders = Total number of students on the A honor roll - X Number of 7th Graders = 360 - X So, if you know the value of X, you can easily calculate the number of students which are from 7th grade on the A honor roll.
Answer:
There are 126 8th grade A honor roll students.
Step-by-step explanation:
Since there are 14 8th grade A honor roll students out of 40 A honor roll students. That means that the fraction is 14/40. After that we do 14/40x360 which results in 126.

what is the inverse of f(x)=2(3^x)
If [tex]f^{-1}(x)[/tex] is the inverse of [tex]f(x)[/tex], then by definition

so that

Answer:
[tex]\sf 5x+6y=12[/tex]
Step-by-step explanation:
[tex]\sf y=-\dfrac{5x}{6}+2[/tex]
Multiply both sides by 6:
[tex]\implies \sf 6 \cdot y=6(-\dfrac{5x}{6}+2)[/tex]
Expand:
[tex]\implies \sf 6y=-5x+12[/tex]
Add 5x to both sides:

The required inequality that represent the given scenario is :
[tex]\qquad \tt \dashrightarrow \:x \geqslant 4[/tex]
where, x is height in feet.
Let's interpret the information given:
4 feet or taller ⇒ the person can be 4 feet or above 4 feetLet's set 'x' as the hypothetical height of a person
Therefore the inequality should be x ≥ 4
⇒ we put x as greater than 4 since the person must be taller than 4
feet to ride the roller coaster
⇒ we also put the '_' under the inequality to signify that the person
can equal 4 feet in height and still be eligible to ride the roller

?
I
Answer:
266 miles
Step-by-step explanation:
Given statement
4 hours and 45 minutesClearly, 45 is 3/4th of an hour. Thus, this statement can also be written as:
⇒ 4 hours and 3(Hour)/4 minutes⇒ 4 hours + 3(Hour)/4 minutes⇒ 4 hours + 0.75(Hour)⇒ 4.75 hoursWe are given that:
56 miles per hourWhen we convert this statement into an equation, we get:
⇒ 56 miles = 1 hourMultiply both sides by 4.75 to obtain the distance in 4.75 hours.
⇒ 56 × 4.75 miles = 1 hour × 4.75⇒ 266 miles = 4.75 hourswhat is the product of 653 and 87

A college student takes the same number of credits each semester. She had 8 credits when she started, and after 7 semesters, she had 92 credits.
Which of these expresses the rate at which she is earning credits
Answer:
12 credits per semester
Step-by-step explanation:
she has 92 in the end but she started off with 8 so your first step is to subtract 8 from 92 which gives you 84 once you get 84 you divide that by 12 you get 7 which means she got 12 credits in each of her 7 semeters
What are the greatest common factors of 21 and 32?
Answer:
1
Step-by-step explanation:
The biggest common factor number is the GCF number. So the greatest common factor 21 and 32 is 1. Also check out the Least Common Multiple of 21 and 32
The greatest common factor of 21 and 32 is 1.
What is Greatest Common Factor?Greatest common factor or GCF of two numbers is defined as the one common factor of the two given numbers which is the greatest of all the common factors.
GCF is also usually known as Highest Common Factor (HCF).
We have to find the greatest common factors of 21 and 32.
One of the method to find GCF is by prime factorization.
First prime factorize the two numbers. The product of the commonly shared prime factors will be the GCF.
If they don't share any common prime factors, then the GCF will be 1.
21 = 3 × 7
32 = 2 × 2 × 2 × 2 × 2
There are no common prime factors, GCF will be 1.
Hence, the greatest common factor of 21 and 32 is 1 since there are no common prime factors.

Write an equation for each situation!
Alright, Nancy, let's do this.
If dimes are d, then quarters is d + 3.
10d + 25(d + 3) = 1090
I'm dealing with cents to get rid of the pesky decimal.
10d + 25d + 75 = 1090
35d = 1015
d = 29
Since quarters = d + 3, there are 32 quarters and 29 dimes.

Evaluate this:
[tex]\displaystyle\rm\int_0^\frac{\pi}{2}\sqrt{\sin x}\ dx \times \int_0^\frac{\pi}{2}\frac{1}{\sqrt{\sin x}}\ dx[/tex]
Only elementary methods are allowed.
The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as
[tex]B(x,y) = \displaystyle \int_0^1 t^{x-1} (1-t)^{y-1} \, dt[/tex]
and satisfies the identity
[tex]\displaystyle B(x,y) = \frac{\Gamma(x) \Gamma(y)}{\Gamma(x+y)}[/tex]
Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,
[tex]\Gamma(z) \Gamma(1-z) = \dfrac{\pi}{\sin(\pi z)}[/tex]
as well as the identity
[tex]\dfrac{\Gamma(z+1)}{\Gamma(z)} = z[/tex]
Replace [tex]x\to\sin^{-1}(x)[/tex] in both integrals, so that
[tex]\displaystyle \int_0^{\frac\pi2} \sqrt{\sin(x)} \, dx = \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx[/tex]
[tex]\displaystyle \int_0^{\frac\pi2} \frac{dx}{\sqrt{\sin(x)}} = \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}}[/tex]
Now replace [tex]x\to\sqrt x[/tex] :
[tex]\displaystyle \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx = \frac12 \int_0^1 x^{-\frac14} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac34, \frac12\right) [/tex]
[tex]\displaystyle \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}} = \frac12 \int_0^1 x^{-\frac34} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac14, \frac12\right)[/tex]
So, the original integral (which I condense here to a double integral) is
[tex]\displaystyle \int_0^{\frac\pi2} \int_0^{\frac\pi2} \sqrt{\frac{\sin(x)}{\sin(y)}} \, dx \, dy = \frac14 B\left(\frac34, \frac12\right) B\left(\frac14, \frac12\right)[/tex]
[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\Gamma\left(\frac54\right) \Gamma\left(\frac34\right)}[/tex]
[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\frac14 \Gamma\left(\frac14\right) \Gamma\left(\frac34\right)}[/tex]
[tex]\displaystyle = \Gamma\left(\frac12\right)^2 = \frac{\pi}{\sin\left(\frac\pi2\right)} = \boxed{\pi}[/tex]
