2.2 + 12x = -4
Answer:
−0.516667
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12x+2.2=−4
Step 2: Subtract 2.2 from both sides.
12x+2.2−2.2=−4−2.2
12x=−6.2
Step 3: Divide both sides by 12.
12x
12
=
−6.2

Each gallon of paint covers $200$ square feet. I have to paint one side of a wall that is $12$ meters tall and $80$ meters long. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
The smallest whole number of gallons require to paint the wall is 52 gallons.
Given that, 1 gallon of paint = 200 ft², 1 foot = 0.3048 meters and dimension of wall is 12 meter by 80 meter.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Converting the dimension to feet :
12/0.3084 = 39.370078 feet
80/0.3084 = 262.46719 feet
Hence, the area of the wall is
Area = Length × width
Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²
Let number of gallons required = x
Since, 1 gallon = 200 ft²
x gallons = 10093.516 ft²
Cross multiply :
200x = 10093.516
x = 10333.35374274082/200
x = 51.6667687137041 gallons
x = 52 gallons
Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint.

#5: Solve the
following
equation
60=5r-4r+14
(Show Work
Here)
Answer:
r = 46
Step-by-step explanation:
To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.
1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.
[tex]60 = 5r-4r + 14\\60 = r + 14[/tex]
2) Now, finally isolate r by subtracting both sides by 14.
[tex]60 = r + 14\\46 = r[/tex]
So, r = 46.

FV = PV(1 + int)^time PV is present value FV is the future value
PV + Interest = FV
FV - PV = Interest
FV - PV
Interest = [3000(1 + 0.03)^30] - 3000

is a + b rational or irrational
Answer:
I think it would be rational
Answer and Step-by-step explanation:
It depends on the numbers that are inputted for a and b.
If the numbers that are inputted for both a and b are rational, then a + b would be rational.
If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.
If one of the variables is rational and the other is irrational, then a + b would be irrational.

Step-by-step explanation:
A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.
Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?
The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Answer:
D. The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

Mr. Powell rents a storage space that is 7 feet high, 5 feet long, and 4 feet wide.
How many containers, each one cubic foot in volume, can Mr. Powell fit into the storage space?
Answer:
To find how many 1 by 1 containers can fit in his storage space we must find the volume of the storage space in cubic feet. The formula for the volume of a rectangular prism aka the room is length x width x height. With this formula, all we need to do is plug in all the values given to the variables.
volume = length x width x height = 5 x 4 x 7 = 20 x 7 = 140
Final Answer: 140 one foot by one foot containers can fit in Mr. Powell's storage space

Nancy has a rectangular garden with length, I, width, w, and a perimeter of 28 feet The length of the rectangle is 2 less than 3 times the width. Choose the system of equations that can be solved to find land w
Answer:Perimeter =2l +2w
28=2(3x-2) + 2x
Width =4feet
Length =10feet
Step-by-step explanation:
Perimeter of rectangular garden =2(l+b)
Let the width be represented as X
And the length which is 3x-2
Such that the equation to solve for length and width be
Perimeter =2l +2w
28=2(3x-2) + 2x--- system of equation
Solving
28=2(3x-2) +2x
28=6x-4+2x
28=8x-4
28+4=8x
32=8x
X=32/8
X=4
Width =4
Length =3x-2=3x4-2=10

List four rational numbers between -1 and 0
Answer:
4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)
Step-by-step explanation:
Rational numbers between two numbers say x and y is given by;
(x + y)/2
Thus;
Rational number between -1 and 0 = (-1 + 0)/2 = -1/2
Rational number between 0 and -1/2 = (-½ + 0)/2 = - 1/4
Rational number between 1 and -1/2 = (-½ + 1)/2 = 1/4
Rational number between 1 and -1/4 = (-1/4 + 1)/2 = ⅜
Thus,4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)

What is the decimal multiplier to increase by 6.1%?
first add or subtract the percentage from 100 ,then convert to a decimal.
What is a simple definition of the multiplier?
It is the number of times a rise in national income exceeds the rise in injections of demand that caused it.
What is the multiplier process?
The multiplier effect comes about because injections of new demand for goods and services into the circular flow of income stimulate further rounds of spending – in other words “one person’s spending is another’s income”
This can lead to a bigger eventual final effect on output and employment.
