You have 2 different savings accounts. For Account A, the simple interest earned after 3 months is $1.75. For Account B, the simple interest earned after 21 months is $17.50. If the interest rate is 3.5% for Account A and 2.5% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
The principal of account A is $20.83 and the principal of account B is $58.33. Account 2 earned the most interest rate in the first month.
The formula to calculate Simple interest, Simple interest = Principal × rate of interest × time.
The principle for Account A would be,
2 = Principal × 3.2% × 3
So, the principal is $20.83
The principle for account B would be,
38.50 = Principal × 2.2% × 30
So, the principal is $58.33,
The interest rate for both accounts is now as follows:
For account 1
= $20.83 × 3.2%
= $0.67
And, for account 2
= $58.33 × 2.2%
= $1.28
Account 2 has the greatest interest rate, thus it is taken into account.

A rectangular box has a volume of 72x cubic inches. The width of the rectangular box is x inches, the legth is 3x inches, and the hieght is (3x-1) inches.
a. Write a polynomial that represents the volume of the retangular box.
b. What are the dimentions of the rectangular box?
The polynomial that represents the volume of the rectangular box is 3x² - x - 24 = 0
The dimension of the rectangular box are 9 inches, 8 inches and 3 inches.
How to find volume of a rectangular box?The volume of the rectangular box can be expressed as follows:
volume of the rectangular box = l w h
where
l = length of the rectangular boxw = width of the rectangular boxh = height of the rectangular boxTherefore,
w = x inches
l = 3x
h = 3x - 1
volume of the rectangular box = 72x
Therefore, the polynomial that represents the volume of the rectangular box is as follows:
72x = 3x × x × (3x - 1)
72x = 3x²(3x - 1)
72x = 9x³ - 3x²
9x³ - 3x² - 72x = 0
3x(3x²- x - 24) = 0
3x² - x - 24 = 0
Therefore,
x = 3 or - 8 / 3
we can only use positive values.
Hence, the dimension of the rectangular box is as follows:
w = 3 inches
l = 3(3) = 9 inches
h = 3(3) - 1 = 8 inches

A.Less than 1
B.Between 1 and 2
C.Between 2 and 3
D.Between 3 and 4
E.More than 4
The layer of dirt would be between 3 and 4 yards and precisely 3.6458 yards.
Given the volume of the lot is 7000 cubic yards.
After spreading to an even layer
The dimension is 30 yards and 64 yards
The volume of the lot can be given as Length x Width x Depth
Let us say the depth of the lot is x

Where,

Under her cell phone plan, Genesis pays a flat cost of $40.50 per month and $5 per gigabyte, or part of a gigabyte. (For example, if she used 2.3 gigabytes, she would have to pay for 3 whole gigabytes.) She wants to keep her bill under $55 per month. What is the maximum whole number of gigabytes of data she can use while staying within her budget?
Using mathematical operations, the maximum whole number of gigabytes of data Genesis can use while staying within her budget is 2GB.
What are mathematical operations?Mathematical operations are used in mathematical functions to produce a defined output.
Some of the mathematical operations include addition, subtraction, multiplication, division, exponentiation, and modulus operations.
In this situation, we used the mathematical operations of subtraction, division, addition, and multiplication to determine Genesis's data maximum usage that does not exceed her budget.
Fixed cost per month = $40.50
Usage rate per gigabyte or part thereof = $5
Budgeted bill = $55 per month
Maximum gigabyte usage per month = 2.9 {($55 - $40.50) ÷ $5}
But Genesis cannot use 3GB but only 2GB because 3GB will make her total bill exceed her budget.
Check:
Cost of using 3GB = $55.50 ($40.50 + $5 x 3)
Cost of using 2GB = $50.50 ($40.50 + $5 x 2)
Thus, for Genesis to maintain her data plan within budget, the maximum she can spend is 2GB.

The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 42 centimeters. Find the length and width of the rectangle.
the length of the rectangle is 10 cm and the width of the rectangle is 11 cm.
We are given that the length and the width of a rectangle are consecutive integers.
Let the length be x
Width = x + 1
Now, we are also given that perimeter is:
P = 42 cm
We know the formula for perimeter of a rectangle is:
P = 2( l + w)
Substituting the values in the formula, we get that:

Inequalities can be expressed as questions, similar to equations, and solved using similar methods, or as factual statements in the type of theorems.For the given question, the graph is shown,
Consider two coordinates from the graph and find the slope using them.
(x₁, y₁) = (0, 2)
(x₂, y₂) = (4, 4)
slope m = (y₂ - y₁)/(x₂ - x₁)
Put the values.
m = (4 - 2)/(4 - 0)
m = 1/2
Put the value of slope in the equation of line in slope intercept form.
y - y₁ = m(x - x₁)
Put the values;
y - 2 = 1/2(x - 0)

a ladder 25 feet long is leaning against the wall of a building. initially, the foot of the ladder is 7 feet from the wall. the foot of the ladder begins to slide at a rate of 2 ft/sec, causing the top of the ladder to slide down the wall. the location of the foot of the ladder, its x coordinate, at time t seconds is given by x(t)
The approximate value of x(t), which indicates the location of coordinate the ladder's foot at time t seconds, is 6.85. 7
What in math is a coordinate?Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicses, scientists, and engineers frequently employ a variety of coordinate systems.
The location in the cartesian plane will be determined by the coordinate points. A point's distance from the y axis is known as the x-coordinate, also known as the abscissa, and its distance from the x-axis is known as the y-coordinate, also known as the ordinate.
based on the information provided,
x = the distance between the wall and the bottom of the ladder
y = distance of the top of the ladder from the ground
x² + y² = 25²
x² + 7² = 25²
x² = 625 -49 = 429
y = √576
Differentiating the equation with respect to time t gives
2x dx/dt + 2y dy/dt = 0
dx/dt = -y dy/dt / x
= -√576 * (2) / 7
= 6.85 feet per second approximately.

Answer:
B) To make a right triangle in the center, the area of the smaller two square must add to equal the area of the largest square
Step-by-step explanation:
1) add the area of the two smaller squares together
f^2= 9
g^2 = 16
9+16=25
2) compare the sum of the two squares to the larger square (the hypotonus)
h^2= 25 so, f^2 + g^2 = h^2
3) The area of the smaller squares is equal to the area of the larger square, therefore b is the correct answer.
Two light bulbs are selected at random from a large batch of bulbs in which 5% are defective. Find the probability that:
a. Both bulbs are defective
b. At least one bulb works
Answer:
a) 0.25% b) 99.75%
Step-by-step explanation:
the chance that one bulb is defective is 0.05, so two bulbs being defective has a chance of 0.05 * 0.05 which equals 0.25%
For at least 1 bulb to work, both bulbs can't be broken. We already know that the chance for both bulbs being broke is 0.25%, so 100%-0.25% would equal the chance that at least one light bulb works, which is 99.75%

Answer: The arrow is pointing to 76.5.
Step-by-step explanation: It's pointing to 76.5 because there are 10 spaces between 75 and 80 so in that case, each line is .5, and since it's on the third line that means it is 1.5 more than 75 so 76.5.
Answer:
C) The arrow points to 76.5.
Step-by-step explanation:
The number line is divided into 10 parts equally.
We can find out the distance between each point by taking the difference between the largest and smallest number on the number line and dividing the difference by 10.
80 - 75 = 5
5/10 = .5
So, the distance between each number/mark on the line is .5
Now, we can label each point by adding .5 to each mark as we go. Then, we'd get this.
*see attachment below
Since the number line constructed here has all the values, we can now tell which value the arrow is pointing to.
The answer is therefore 76.5.
