You have 2 different savings accounts. For Account A, the simple interest earned after 9 months is $6.94. For
Account B, the simple interest earned after 33 months is $39.60. If the interest rate is 3.7% for Account A and 2.4% for
Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain
Answers
The principal amount in account A was $250.09 and in account B it was $600.
Account B earned you the most interest the first month because $1.2 is higher than $0.7711.
What is the simple interest?
Simple interest is a quick and easy way to calculate the interest charge on a loan. Simple interest is calculated by multiplying the daily interest rate by the principal by the number of days between payments.
The formula for simple interest is expressed as
I = PRT/100
Where, P = the principal or initial amount of money invested.
R = interest rate
T = time
On account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years.
Using the formula:
I = PRT/100
[tex]6.94 = \frac{P(3.7)(0.75)}{100} \\\\6.94 = 0.02775P\\\\P=250.09[/tex]
On account B,
I = $39.60
R = 2.4%
T = 33 months = 33/12 = 2.75 years
Using the formula:
I = PRT/100
[tex]39.60= \frac{P(2.4)(2.75)}{100} \\\\39.60 = 0.066P\\\\P=600[/tex]
To find the account that earned more interest in the first month we have to divide the interest by the number of months.
For account A,
6.94/9 = $0.7711
For account B,
39.60/33 = $1.2
Hence, the principal amount in account A was $250.09 and in account B it was $600.
Account B earned you the most interest the first month because $1.2 is higher than $0.7711.

If they need exactly 18 stickers to completely cover the width of the wall, how many whole stickers can they fit across the length of the wall?
Answers
Answer:
cm2 to inch2 conversion. Conversion square centimeters to square inches, cm2 to inch2. The conversion factor is 0.15500031000062; so 1 square centimeter ...
Step-by-step explanation:
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
The perimeter of a rectangle.
= 2 ( length + width)
The number of 2(3/8) inches tickets to fit into the length of the wall is
154 tickets.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
The perimeter of a rectangle.
= 2 ( length + width)
The wall is rectangular and has a perimeter of 408 ⅜ inches.
This means,
408 (3/8) = 2 (length + width)
3267/8 = 2 (length + width) _____(1)
Now,
The total width of the wall.
= 2 width
Now,
Length of the square stickers = 2 (3/8) inches = 19/8 inches
The number of stickers needed to cover the width of the wall = 18
2 width = 18 x 19/8 inches.
2width = 18 x 19/8
width = 171/8 inches
Now,
From (1) we get,
3267/8 = 2 (length + width)
3267/8 = 2 (length + 171/8)
3267/8 - 342/8 = 2 length
2925/(8 x 2) = length
2length = 2925/(8 x 2)
2length = 2925/8
The number of stickers to cover the total length.
= 2925/8 ÷19/8
= (2925 x 8)/ (19 x 8)
= 154
Thus,
The number of 2(3/8) inches tickets to fit into the length of the wall is
154 tickets.

Answers
The intermediate step of equation x^{2}+32x+116=0 is (x + 16)² = 140
In this question, we have been given an equation x^{2}+32x+116=0
We need to find the intermediate step in the form (x + a)^2=b as a result of completing the square for the given equation
We can write given equation as,
x^{2}+32x= -116
Take the coefficient of x
k = 32
Divide it by 2
k/2 = 16
Square both sides
(k/2)^2 = 256
Add 256 to both sides of x² + 32x = -116
x² + 32x + 256 = -116 + 256
(x + 16)² = 140
Therefore, the intermediate step of equation x^{2}+32x+116=0 is (x + 16)² = 140

Q(t) = C/4t -1
Put a "y" in place of the "Q(t)":

Change the t and y since each (t, y) has a corresponding (y, t) companion.
t = C/4y -1
Distribute t by multiplying into the bracket to find y.
t × 4y -1 = C
t × 4y - t = C
Add both sides of the equation together now.

Answers
If a person substitutes 2 ounces of lean meat by cooked lentils, the lentils that the person need to eat is ½ cup as both are protein.
Lean meat and lentils are among the sources of proteins in the food intake. Protein is found throughout the human body such as in muscle, skin, hair, bone, skin, hair, and every other body part or tissue. It manufactures the enzymes that power chemical reactions and the hemoglobin that carries oxygen in your blood. Protein is required by the body to help your body repair and make new cells. The foods that contain high content of proteins include lean meat, eggs, dairy products, lentils, etc. A half cup of cooked lentils provides 9 grams of protein, and 2 ounces of lean meat provides 8 grams of proteins.

Mathew drives m miles in x hours. How many hours would he save if he drove the same distance at k miles per hour
Answers
The time saved will be: x - m/k This is a simple exercise in manipulating symbols. Let's take a look at the problem and break it down. "Stanley drives m miles in x hours" This statement immediately gives us 2 variables; "m" to represent how many miles the trip is and "x" for the number of hours it took Stanley to drive that far. Now let's look at the next statement. "How many hours would he save if he drove the same distance at k miles per hour?" This statement gives us another variable "k" for a new speed and gives us the question to answer. How many hours would Stanley save if he made the trip at a different speed. Since we're interested in hours saved, we need 2 different time values. They are 1. How much time did Stanley originally take? 2. How much time will the new speed make Stanley take? Looking at m, x, and k. We can immediately see that x is the original time that Stanley took. So we have that value. But we don't have any value for how long will it take at a new speed. But can we calculate it? And the answer to that is YES. The time it will take is the distance divided by the new speed. And that would be m/k. And since we're looking for savings, we just need to subtract the two time values. So our equation becomes x - m/k where x = original time taken m = distance of trip k = new speed to drive at.
