A large amount of peanuts was divided equally into 6 small bags. The total number of peanuts, p, was 342. Which statements can be used to write an expression and then find the number of peanuts that ended up in each bag? Check all that apply.
The operation is division.
The operation is multiplication.
The variable is the number of bags.
342 divided by 6 equals 57.
Write the division expression as a fraction, StartFraction p Over 6 EndFraction.
To evaluate, substitute 342 for the variable.
Each bag will have 57 peanuts.
The constant is 342.

Answer:
Step-by-step explanation:
6 P = 342
To solve the question, you need to divide by 6
You don't multiply
The operation is division
The variable is the number of peanuts in each bag.
The answer is 57
The last two are incorrect.
x/p // 6 / end fraction

What are Trigonometry Functions ?
Real functions which relate to an angle of a right angled triangle to ratios of two side length.
Given
tan (theta) = 4`
sin(theta) = tan (theta ) / (1 + tan ^ theta)^(1/2)
sin(theta) = 4/(1+(4)^2)^(1/2)
= 4/ (17)^ (1/2)
multiplying and dividing by 17 ^ (1/2), we get
= -4 (17) ^ (1/2) / 17 ( negative since angle is in third quadrant and tan is negative in that quadrant )

A ladder is 6 m long.
The ladder is placed on horizontal ground, resting against a vertical wall.
The instructions for using the ladder say that the bottom of the ladder must not be closer than 1.5 m
from the bottom of the wall.
How far up the wall can the ladder reach?
Answers
Answer:
5.8 m
Step-by-step explanation:
Using the Pythagorean Theorem (a² + b² = c²) you get the equation a² + 1.5² = 6² (or 1.5² + b² = 6²). Then you solve from there and rounding to the first decimal place you get 5.8
The ladder can reach a height of 5.6 meters.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have a ladder that is resting against a wall.
Now, assume that the ladder can reach a height of [x] meters. Then when the bottom is at a horizontal distance of 1.5 meters, then we will get a right angled triangle with base = 1.5 m and hypotenuse = 6m. So, using Pythagoras theorem, we can write -
(6 x 6) = x² + (1.5 x 1.5)
x² = (6 x 6) - (1.5 x 1.5)
x² = 7.5 x 4.5
x² = 33.75
x = 5.6 meters
Therefore, the ladder can reach a height of 5.6 meters.

2. Nick and Adam workout together. Nick weighs
160 pounds and is gaining about 3 pounds per
week. Adam weighs 195 pounds and is los ng
about 2 pounds each week. Write an equation
that can be used to find the number of weeks
that it will take them to weigh the same amount.
a. Equation:
b. Solution:
c. How much will Nick and Adam weigh?
Answers
Answer:
Equation: 160 + 3x = 195 - 2x
Solution: 7 weeks
Step-by-step explanation:
x is going to stand for the number of weeks
Nick:
160 + 3x
Adam:
195 - 2x
Equation: 160 + 3x = 195 - 2x
Solution: 7
They would weigh 181 pounds
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
a.
Let w be the number of weeks, then the equation to find when Nick and Adam will weigh the same amount is:
160 + 3w = 195 - 2w
b.
To solve for w, we can simplify the equation:
160 + 3w = 195 - 2w
5w = 35
w = 7
c.
To find how much Nick and Adam will weigh after 7 weeks, we can plug w = 7 into either of the original equations:
Nick's weight = 160 + 3w = 160 + 3(7) = 181 pounds
Adam's weight = 195 - 2w = 195 - 2(7) = 181 pounds
Thus,
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.
