Simpson has a rectangular fish aquarium that measures 31 inches long, 13 inches wide, and is 28 inches deep. If Simpson wanted to put a protective covering on the four glass walls of the aquarium, how much covering does he need?
The dimensions of the rectangular fish aquarium are:
length = 31 inches, width = 13 inches and depth = 28 inches
If Simpson covers all the four glass walls of the aquarium.
We have to determine the covering he needs.
So, Covering required for four walls of the aquarium
= [tex]2(lh+bh)[/tex]
= [tex]2( (31 \times 28)+ (13 \times 28))[/tex]
= [tex]2( (868)+ (364))[/tex]
= [tex]2 \times 1232[/tex]
= 2464 square inches
So, Simpson needs 2464 square inches of covering to cover all the four glass walls of the aquarium.
What percent of 82.5 is 21.12
The 25.6 percentage of the number 82.5 is 21.12
Given data:
To find the percentage of 21.12 in relation to 82.5, the proportion is simplified as:
21.12 is to 82.5 as x is to 100.
This can be expressed as:
21.12/82.5 = x/100
On solving for x by cross multiplying:
21.12 * 100 = 82.5 * x
2112 = 82.5x
To isolate x, divide both sides by 82.5:
2112/82.5 = x
On simplifying:
25.6 ≈ x
Hence, 21.12 is approximately 25.6 percent of 82.5.

Jim and Gail invested a total of $3,600 in a stock, in a ratio of 5:7. The stock made $6,450 on top of the initial capital. If the payoff is done in the same ratio, how much does Gail get?
"Since the ratio is 5:7 you can think in total there was 12 equal blocks of money invested. 5 of those blocks belonged to Jim and 7 of those blocks belonged to Gail. Since they invested $3,600 and then made $6,450 in total there is $10,050. Divide that total into 12 equal blocks of $837.50 and 5 of those blocks belong to Jim. So he will get $4,187.50"
The amount that Gail will get is $5862.5.
What is Ratio?A ratio is a comparison of two quantities produced by dividing the first by the second. If a and b are two values of the same kind and with the same units, and b is not equal to zero, then the quotient a/b is known as the ratio between a and b. The colon sign is used to denote ratios (:). This means that the ratio a/b has no unit and can be expressed as a: b.
Given:
Jim and Gail invested a total of $3,600 in a stock, in a ratio of 5:7.
The stock made $6,450 on top of the initial capital.
Total they made
= 3600+ 6450
= $10, 050
The pay off Jim get
= 10, 050 x 5/12
= 4187.5
and, the pay off Gail get
= 10, 050 x 7/12
= $5862.5

leave answer as a fraction in simplest form
Remember to show all of you work
By using the tangent formula, we will see that:
tan(x) = 5/12.
How to get the tangent of x?You just need to remember that we can write the tangent as:
tan(x) = sin(x)/cos(x).
In this case, we know that:
sin(x) = 5/13cos(x) = 12/13We can just replace these two in the tangent equation, we will get:
tan(x) = (5/13)/(12/13) = (5/13)*(13/12) = 5/12
tan(x) = 5/12

Kevin plans to put concrete on a rectangular portion of his driveway. The portion is 10 feet long and three inches high. The price of concrete is $98 per cubic yard. The total cost of the concrete Kevin needs is $72.59. Which of the following is closest to the width of the portion of the driveway on which Kevin plans to put concrete?
[1 foot = 12 inches; 1 yard = 3 feet]
3 feet
6 feet
8 feet
10 feet
Answer:
Option C is the correct answer.
Step-by-step explanation:
Volume = Length x Breadth x Height
Length = 10 feet = 3.33 yard
Height = 3 inches = 0.25 feet = 0.0833 yard
The price of concrete is $98 per cubic yard and total cost is $72.59.
[tex]\texttt{Total concrete needed = }\frac{72.59}{98}=0.74yard^3[/tex]
We have
Volume = Length x Breadth x Height = 0.74
3.33 x Width x 0.0833 = 0.74
Width = 2.67 yards = 2.67 x 3 = 8 feet
Option C is the correct answer.

find the LA, SA, and volume of a triangular prism with a hypotenuse of 12m, short leg of 5m, and height of prism of 5m
To find the lateral area, surface area, and volume of a triangular prism, use the Pythagorean theorem to find the missing leg, then calculate the triangular base area, lateral area, and volume, and finally add the triangular base areas to the lateral area for the surface area.
Explanation:Finding the Lateral Area, Surface Area, and Volume of a Triangular Prism
To find the lateral area (LA), surface area (SA), and volume of a triangular prism with a given hypotenuse, short leg, and height of the prism, we will follow these steps:
Determine the length of the other leg of the right-angled triangle using the Pythagorean theorem (since the triangular face is a right triangle given the hypotenuse and one leg).
Calculate the area of the triangular base using the formula for the area of a triangle (1/2 × base × height).
Compute the lateral area by multiplying the perimeter of the triangular base by the height of the prism.
Add the areas of the two triangular bases to the lateral area to get the surface area.
Find the volume by multiplying the area of the triangular base by the height of the prism.
Since the short leg is 5 m and the hypotenuse is 12 m, the other leg (long leg) can be found as √(12² - 5²) = √(144 - 25) = √119 m. The area of the triangular base (A) is then 1/2 × 5 m × √119 m. The perimeter (P) of the triangular base is 5 m + 12 m + √119 m. The lateral area is P × height of prism (5 m), and the surface area is LA + 2 × A. Lastly, the volume is A × height of prism (5 m).

Body temperatures are normally distributed with a mean of 98.6° f and a standard deviation of 0.19° f. what temperature represents the 95th percentile?
To find the temperature that represents the 95th percentile, calculate the z-score using the given formula and substitute the values in the equation. Using a standard normal distribution table, the temperature is approximately 98.93°F.
Explanation:To find the temperature that represents the 95th percentile, we need to calculate the z-score corresponding to the 95th percentile.
The z-score can be calculated using the formula: z = (x - μ) / σ, where x is the temperature, μ is the mean, and σ is the standard deviation. In this case, μ = 98.6°F and σ = 0.19°F.
By looking up the z-score in the standard normal distribution table, we can find the corresponding temperature.
Using a standard normal distribution table, we find that the z-score for the 95th percentile is approximately 1.645. Substituting the values into the formula, we get: 1.645 = (x - 98.6) / 0.19.
Solving for x, we find x ≈ 98.6 + (1.645 * 0.19) ≈ 98.9295°F.
Therefore, the temperature that represents the 95th percentile is approximately 98.93°F.

The measure of the longest side of ∆ABC is 6 units. ∆ABC is a right scalene triangle. ∆ABD is also a right scalene triangle and the length of side AD is 5 units.
The measure of the longest side of ∆ABC can be found using the distance formula.
We calculate the distance between points A(1, 7) and B(-2, 2), between points B(-2, 2) and C(4, 2), and between points A(1, 7) and C(4, 2).
The longest distance is the measure of the longest side.
Using the distance formula, we find that the longest side is 6 units long.
∆ABC is a right scalene triangle.
This is because the lengths of its sides are all different and it has a right angle at point C, where the x-coordinate doesn't change but the y-coordinate does.
∆ABD is also a right scalene triangle.
The length of side AD can be found using the distance formula between points A(1, 7) and D(1, 2).
The length of side AD is 5 units.
