Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The Balance after the fifth year from now is 3801.56.


What is simple interest?

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = PRT

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

The balance in the accounts can be calculated as,

Balance after the first year,

A = 600×(1.08) = 648

Balance after the second year,

A = (600+648)(1.08) = 1248(1.08) = 1347.84

Balance after the third year,

A = (1347.84+600)(1.08) = 1947.84 (1.08) = 2103.67

Balance after the fourth year,

A = (2103.67+600)(1.08) = 2703.67 (1.08) = 2919.96

Balance after the fifth year,

A = (2919.96+600)(1.08) = 3519.96 (1.08) = 3801.56

Hence, the Balance after the fifth year from now is 3801.56.

Suppose a family starts out 50 miles from home at time t = 0. They travel away from home at a constant speed of 45 miles an hour. What's the equation that tells you how far they'll be from home t hours later? (Assume d is distance in miles.) A. d = 45t + 50 B. d = 45t C. d = 50t D. d = 50t + 45

Answers

50 miles, t=0 is the start
45 miles each 1 hour

A. d= 45•t+50
At t = 0  d = 50.
At time = 1 hour , d = 50 + 45(1)
At time = 2 hours, d = 50 + 45(2)

So its d = 50 + 45t  or  d = 45t + 50

Engineers must consider the breadths of male heads when designing motorcycle helmets. men have head breadths that are normally distributed with a mean of 6.0 in and a standard deviation of 1.0 in. (based on anthropometric survey data from gordon, churchill, et al.). if one male is randomly selected, find the probability that his head breadth is less than 6.2 in. use 4 decimals for your answer.

Answers

Answer: 0.9772 (the answer above wasn't the right one;)


Using z-score formula, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

What is z-score formula?

When you have multiple samples and want to describe the standard deviation of those sample means (the standard error), you would use this z score formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

This z-score will tell you how many standard errors there are between the sample mean and the population mean.

We have been given that men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inches. We are asked to find the probability that a man's breadth is less than 6.2 inches.

First of all, we will find z-score corresponding to sample score of 6.2 as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

where,

z = Z-score,

x = Sample score,

[tex]\mu[/tex] = Mean,

[tex]\sigma[/tex] = Standard deviation.

Upon substituting our given values in z-score formula, we will get:

[tex]z=\frac{6.2-6.0}{1.0}[/tex]

[tex]z=\frac{0.2}{1.0}[/tex]

z = 0.2

Now, we need to find the probability that a z-score is less than 0.2.

Using normal distribution table, we will get:

P(z < 0.2) = 0.57926

0.579261 ≈ 57.9261 %

Therefore, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation below could be used to find the side length, x, of the box needed to reach that volume.

Answers

We are to find the side length of the box

Volume = Length * Breadth * Height


Volume of box = 450 cubic inches

Height of box = 2 inches

Length of box = x

Since it is a square prism, Breadth = Length = x


Therefore,

Volume = Length * Breadth * Height

⇒ 450 = 2 * x * x

⇒ 450 = 2x²

⇒ 2x² = 450


Divide the equation by 2

2x²/2 = 450/2

x² = 225

⇒√x² = √225

x = 15

The side length of the box is 15 inches


Answer:

The solutions are -15 and 15, but only 15 is a reasonable side length.

 We write the following system of equations:
 x + y = 121
 y = 13 + x
 Solving the system we have:
 Step 1:
 x + (13 + x) = 121
 2x + 13 = 121

Answers

Solve for x:
5 - sqrt(x) + sqrt(3 x - 11) = 6

Subtract 5 from both sides:
sqrt(3 x - 11) - sqrt(x) = 1

(sqrt(3 x - 11) - sqrt(x))^2 = -11 + 4 x - 2 sqrt(x) sqrt(3 x - 11) = -11 + 4 x - 2 sqrt(x (3 x - 11)) = 1:
-11 + 4 x - 2 sqrt(x (3 x - 11)) = 1

Subtract 4 x - 11 from both sides:
-2 sqrt(x (3 x - 11)) = 12 - 4 x

Raise both sides to the power of two:
4 x (3 x - 11) = (12 - 4 x)^2

Expand out terms of the left hand side:
12 x^2 - 44 x = (12 - 4 x)^2

Expand out terms of the right hand side:
12 x^2 - 44 x = 16 x^2 - 96 x + 144

Subtract 16 x^2 - 96 x + 144 from both sides:
-4 x^2 + 52 x - 144 = 0

The left hand side factors into a product with three terms:
-4 (x - 9) (x - 4) = 0

Divide both sides by -4:
(x - 9) (x - 4) = 0

Split into two equations:
x - 9 = 0 or x - 4 = 0

Add 9 to both sides:
x = 9 or x - 4 = 0

Add 4 to both sides:
x = 9 or x = 4

∠A + ∠B + ∠C = 180°

Now we have three cases:

Case 1 : For right anlge triangle.

in this case one angle is 90°. and rest of two angle's sum is 90 degree

it means measure of rest two anles is less than 90 degree.

So, this type trianlge holds one right anlge and two acute angle.

Case 2: If one angle is Obtuse angle(more than 90°)

In this case , rest of two angle's sum is less than 90°

So, this type trianlge holds one obtuse anlge and two acute angle.

Case 3: All angles are acute

In this case all three anles are less than 90°

So, triangle has one obtuse angle, that means rest of two anlges must be less than 90°

There are 12 ways Jackson can order his hot cocoa by choosing from three flavors, two mug sizes, and the option of adding marshmallows. Option D is correct,

To find the total number of ways Jackson can order his hot cocoa, we need to consider all the possible combinations of choices he has.

1. Flavor: Jackson has 3 options: milk chocolate, dark chocolate, or chocolate mint flavor.

2. Mug Size: Jackson has 2 options: small or large mug.

3. Marshmallows: Jackson has 2 options: with or without marshmallows.

To find the total number of combinations, we multiply the number of options for each choice:

[tex]\[ \text{Total combinations} = \text{Number of options for flavor} \times \text{Number of options for mug size} \times \text{Number of options for marshmallows} \]\[ \text{Total combinations} = 3 \times 2 \times 2 \]\[ \text{Total combinations} = 12 \][/tex]

So, there are 12 ways Jackson can order his hot cocoa. Therefore, the correct answer is option D) 12.

Titus had 1/2 can of paint. He used 2/3 to paint a tabletop. What fraction of a full can of paint did Titus use?

Answers

Final answer:

Titus had half a can of paint and used two-thirds of it, which means he used (1/2) * (2/3) = 2/6, which simplifies to 1/3 of a full can of paint.

Explanation:

The student is asking about how to calculate the fraction of a full can of paint Titus used given that he had half a can and used two-thirds of it. To find out what fraction of the full can he used, you need to perform a multiplication of the two fractions.

Here is the step-by-step calculation:

Write down the fractions: 1/2 (half a can of paint Titus had) and 2/3 (the fraction he used).Multiply these two fractions: (1/2) \\times\ (2/3)Simplify the multiplication: The numerators are multiplied together and the denominators are multiplied together: (1 \\times\ 2)/(2 \\times\ 3) = 2/6Reduce the fraction, if possible: 2/6 can be simplified to 1/3 by dividing both numerator and denominator by 2.

Therefore, Titus used 1/3 of a full can of paint.
