Denise wants to cover a 21.75 square foot wall with weathered wood. If each box of weathered wood contains 1.5 square feet of wood, how many boxes of weathered wood does she need?
Answer: 15 boxes
Step-by-step explanation:
From the question, we are informed that Denise wants to cover a 21.75 square foot wall with weathered wood and that each box of weathered wood contains 1.5 square feet of wood.
The number of boxes of weathered wood that she need will be calculated by dividing 21.75 square feet by 1.5 square feet. This will be:
= 21.75/1.5
= 14.5
= 15 boxes approximately

f(x)=x^2-4x-5
Answer:
the answer for me was b
Step-by-step explanation:
A quadratic function,
f(x) = x²-4x-5 have 2 roots.
What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
Given:
A quadratic function,
f(x) = x²-4x-5.
To find the roots:
f(x) = x²-5x+ x -5.
f(x) = (x - 5) (x+ 1)
The roots are x = 5 and -1.
Therefore, the roots are x = 5 and -1.

Identify the slope of the following line y = - 2x + 7
Pleasee
Answer:
-2 or -2/1
Step-by-step explanation:
Since the equation is in y = mx + b form with m equaling the slope, we can see that -2 is in m's place, so -2 is the slope.
what is the y- intercept of y=1+6x?

y is the dependent variable = 1 is the y intercept and 6 is the slope and x is the independent variable.
Therefore, y intercept is 1
Angle A and angle B are vertical angles with M angle A= x and M angle B equals 3X -60. What is M angle A
Answer:
m angle A = x = 30 degrees
Step-by-step explanation:
Vertical angles are equal.
So 3x - 60 = x
2x = 60
x = 30
Answer:
Vertical angles are always equal.
So you can set the equation up like this:
5x + 10 = 7x - 12
Subtract 5x from both sides. Then Add 12 to both sides.
22 = 2x
Divide both sides by 2.
11 = x

What is a Proportional Relationship?A proportional Relationship is when a variable is in direct variation to another variable such that on increasing one the other proportionally increases.
The equation for a proportional relationship is
y ∝ x
y =kx
where k is the proportionality constant
The equation of a straight line is y = mx +c
here c is the intercept on the y-axis
Comparing the two equations, this can be confirmed that
c = 0
Therefore, the line intersects the y-axis of the graph at the origin.

Ms. W has 400 followers on Twitter and is gaining 75 followers each day. Mrs. Hill has 1,000 followers on Twitter, but is losing 25 followers a day. How many days will it take them to have the same number of followers?
Answer:
It takes 6 days.
Step-by-step explanation:
First, you have to form expressions for both of them in terms of x. Let x be the number of days :
Ms. W = 400 + 75x
Mrs. Hill = 1000 - 25x
Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :
400 + 75x = 1000 - 25x
75x + 25x = 1000 - 400
100x = 600
x = 6

A bathtub holds 80 gallons of water. Water drains out of the tub at a rate of 2 gallons every thirty seconds. At this rate, how many minutes will it take a full bathtub to drain completely?
Given :
A bathtub holds 80 gallons of water.
Water drains out of the tub at a rate of 2 gallons every thirty seconds.
To Find :
How many minutes will it take a full bathtub to drain completely.
Solution :
We know, 30 seconds = 0.5 minute.
Rate of water flow per minute is given by :
[tex]R = \dfrac{2}{0.5}=4 \ gallons/min[/tex]
Let, bathtub will completely drain in x minutes.
So, 4x = 80
x = 80/4
x = 20 minutes
Hence, this is the required solution.

To figure out your friend's error, solve the equation yourself.
Distribute the 5 to get 25x+30Combine like terms in the first equation toget 25x-3=25x+30Add 3 to the other side.When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.
