The number of fish caught on a fishing trip varies directly as the number of boats that are fishing. There are 800 fish caught when 16 boats are fishing. How many fish will be caught if 6 boats are fishing? 300
Answer:
300 fish
Step-by-step explanation:
First you divide the 800 by 16 then you get 50
Next you multiply the 50 by 6
Finally you get the answer 300 fish
Three consecutive integers have a sum of 87. Find the integers.
Answer:
28, 29, and 30
Step-by-step explanation:
There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.

Mr. Meyer is planning a sixth-grade field trip to Washington DC. He divides his students evenly between 9 chaperones will lead a group of 8 students. If S represents the total number of students going on the field trip with equation models the problem?
A. 8s = 9
Or
B. s/9 =8
I think there is 72 students because there is 9 chaperones with groups of 8 so that is 9x8 which is 72

The value of the variable 'x' will be 2√2 units. Then the correct option is C.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The two triangular legs and their opposing angles are congruent in an isosceles triangle.
The triangle is an isosceles right-angle triangle. Then by the Pythagoras theorem, we have
4² = x² + x²
2x² = 16
x² = 8
x = 2√2
The value of the variable 'x' will be 2√2 units. Then the correct option is C.

Answer:
-30°
or 330° or -150° or 210°
Step-by-step explanation:
The angle whose sine is 1/2 is 30°. Here, the sine is negative, indicating the angle is in the 3rd or 4th quadrants.
The angles in those quadrants with a reference angle of 30° are -30° or -150°. As positive angles, these are 330° or 210°, respectively.
Generally, the sin⁻¹ function (also called the arcsin function) is defined to have a range of -90° to +90°. Within that range, we can say ...
sin⁻¹(-1/2) = -30°
_____
Additional comment
There are a few trig functions it is worthwhile to remember. These are shown in the attachment. The ordered pair points on the unit circle are (cos(θ), sin(θ)). If you remember the values of these in the first quadrant for 30°, 45°, and 60°, then you can work most of these "without a calculator" problems. (You also need to know how the signs change in the different quadrants.)
Answer:
210 degrees
Step-by-step explanation:
This is the 'arcsin' or 'inverse sine' function. As written,
arcsin (-1/2) is requesting the angle (in degrees) whose sine is -1/2.
Note that because the sine function is defined as (opposite side)/hypotenuse, the following equation is true:
-1 opposite
------ = ------------------- = sin x, where x is an angle in degrees.
2 hypotenuse
If the sine is negative, that means that the angle x lies in either Quadrant III or Quadrant IV. We see that the magnitude of the opposite side is HALF the magnitude of the hypotenuse.
Cycling counterclockwise from the positive x axis, and continuing through Quadrant II into Quadrant III, we get a ray (hypotenuse) that is twice the length of the opposite side. The angle of this ray as measured from the positive x-axis is 180 degrees plus 30 degrees, or 210 degrees.
You can check this by finding sin 210° on a calculator; the result is -1/2, which is what we were given up front.

Let's compare two different raffles to see which ticket you should buy? A. Raffle 1: 800 raffle tickets are sold $2.00 each. There is one gran prize for $450 and two consolation prizes of $100 each that will be awarded. What is the expected value of one ticket? B. Raffle 2: 350 raffle tickets are sold for $2.00 each. There is one grand prize of $150 and three consolation prizes of $50 each. What is the expected value of one ticket?
Answer:
(a) The expected value is: $0.40625
(b) The expected value is: $0.4286
Step-by-step explanation:
Solving (a): Raffle 1
Given
[tex]Tickets=800[/tex]
[tex]Value = \$2[/tex] per ticket
[tex]Grand\ Prize = \$450[/tex] ---- for 1
[tex]Consolation = \$100[/tex] --- for 2
Required
The expected value of each ticket
First, calculate the total amount of the 800 tickets
[tex]Amount = Tickets * Value[/tex]
[tex]A_1 = 800 * \$2[/tex]
[tex]A_1 = \$1600[/tex]
Next, calculate the total amount of the prizes
[tex]Amount = Tickets * Value[/tex]
[tex]A_2 = \$450 * 1 +\$100 * 2[/tex]
[tex]A_2 = \$450 +\$200[/tex]
[tex]A_2 = \$650[/tex]
The expected value E(x) of 1 ticket is calculated as:
[tex]E(x) = \frac{A_2}{A_1}[/tex]
[tex]E(x) = \frac{\$650}{\$1600}[/tex]
[tex]E(x) = \$0.40625[/tex]
Solving (b): Raffle 2
Given
[tex]Tickets=350[/tex]
[tex]Value = \$2[/tex] per ticket
[tex]Grand\ Prize = \$150[/tex] ---- for 1
[tex]Consolation = \$50[/tex] --- for 3
Required
The expected value of each ticket
First, calculate the total amount of the 800 tickets
[tex]Amount = Tickets * Value[/tex]
[tex]A_1 = 350 * \$2[/tex]
[tex]A_1 = \$700[/tex]
Next, calculate the total amount of the prizes
[tex]Amount = Tickets * Value[/tex]
[tex]A_2 = \$150 * 1 +\$50 * 3[/tex]
[tex]A_2 = \$150 +\$150[/tex]
[tex]A_2 = \$300[/tex]
The expected value E(x) of 1 ticket is calculated as:
[tex]E(x) = \frac{A_2}{A_1}[/tex]
[tex]E(x) = \frac{\$300}{\$700}[/tex]
[tex]E(x) = \$0.4286[/tex]
What is the salesperson's commission on a $900
sale if the commission rate is 25%?
Answer:
Amount of commission earned = $225
Step-by-step explanation:
Commission rate = 25%
Sales amount = $900
Find the amount of commission earned by the salesperson
Amount of commission earned = Commission rate × Sales amount
= 25% × $900
= 25/100 × $900
= 0.25 × $900
= $225
Amount of commission earned = $225

#2: 3^8*3^n
#3: 2^2n/2^n
#4: 2^3n/2^2n
Pictures of each question will also be attached.
The powers in this problem are expressed as follows:
1. 4^n x 4^5 = 4^(n + 5).
2. 3^8 x 3^n = 3^(8 + n).
3. 2^(2n)/2^n = 2^n
4. 2^(3n)/2^(2n) = 2^n
Exponents and multiplicationWhen two terms with the same base and different exponents are multiplied, we keep the base and add the exponents to find the product.
In the context of this problem, this is what we use for items 1 and 2, as follows:
1. 4^n x 4^5 = 4^(n + 5). -> Base 4, exponents n and 5, n + 5 = n + 5.
2. 3^8 x 3^n = 3^(8 + n). -> Base 3, exponents 8 and n, 8 + n = 8 + n.
Exponents and divisionWhen two terms with the same base and different exponents are divided, we keep the base and subtract the exponents to find the quotient.
In the context of this problem, this is what we use for items 3 and 4, as follows:
3. 2^(2n)/2^n = 2^n -> Base 2, exponents 2n and n, 2n - n = n.
4. 2^(3n)/2^(2n) = 2^n -> Base 2, exponents 3n and 2n, 3n - 2n = n.

A recipe for homemade clay calls for 6 cups of water for every 12 cups. How many cups of water are needed when 4 cups of flour are used ?
Answer:
2 cups of clay
Step-by-step explanation:
Given data
we are given that 6 cups of water for every 12 cups of clay
i.e
12 cups of clay require 6 cups of water
4 cups of clay will require x cups of water
cross multiply
12x= 4*6
12x= 24
divide both sides by 12
x= 24/12
x= 2cups
Hence 4 cups of water will require 2 cups of clay
somebody please help me with this question and no links!
Answer:

The measure of angle MKL is xº.
What is the value of x
Answer: 45
Step-by-step explanation:
Hello there!
So this problem looks a lot more complex than it really is. First, we need to know that a straight line is 180 degrees. Since both of these angles must add up to 180, we just subtract 135 from 180. We then get 45.
