A library has an aquarium in the shape of a rectangular prism. The base is 6 ft by 2.5 ft. The height is 4 ft. How many square feet of glass was used to build the aquarium?
Step-by-step explanation:
Solve the problem step by step.
First,
Base area: 6 * 2.5 = 15
Then,
The area of the two smallersides:
2.5 * 4 = 10
10 * 2 = 20
After that,
The area of the two larger sides:
6 * 4 = 24
24 * 2 = 48
After all of the calculations, you add all of the sums up:
15+20+48
Which equals 83.
The equation form for this problem would be:
(6*2.5) + 2(2.5*4) + 2(6*4) = 83
Hope this helps and it wasn't too confusing!
Suppose you drop a ball from a height of 10 feet. After the ball hits the floor, it rebounds to a height defined by the recursive formula an = 0. 85an – 1. What is a1? feet What is the height the ball rebounds to after its third bounce? Round your answer to three decimal places. Feet.
The height the ball rebounds to after its third bounce with the initial height by 10 feet is 6.141 feet.
What is Algebra?Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
Suppose you drop a ball from a height of 10 feet. After the ball hits the floor, it rebounds to a height defined by the recursive formula
[tex]\rm a_n = 0. 85\ a_{n - 1}[/tex]
a₀ = 10 feet
For n = 1, the height will be
[tex]\rm a_1 = 0. 85\ a_{0}\\\\a_1 = 0.85*10\\\\a_1 = 8.5[/tex]
For n = 2, the height will be
[tex]\rm a_2 = 0. 85\ a_{1}\\\\a_2 = 0.85*8.5\\\\a_2 = 7.225[/tex]
For n = 3, the height will be

Henry deposited $250 into a savings account that earns 1.9% simple interest. How much will his account be worth at the end of 10 years?
Answer:
$297.5
Step-by-step explanation:
I = Prt/100
I = Interest
P = Amount deposited initially
r = Rate
t = number of years
I = Prt/100
= 250 × 1.9 × 10 / 100
= 25 × 1.9
= 47.5
That is the interest
The total amount in his account will be Initial amount + interest
250 + 47.5
= $297.5

What are the coordinates of the focus of the parabola? (0,2) (0,–2) (2,0) (–2,0)
The focus of the parabola is at the point (0, 2).
What is the focus of the parabola?A parabola's focus can be found on the side of the concavity, at the same distance from the vertex as from the directrix, and at the same distance from the vertex to the parabola's centre of gravity.
This is actually a great geometrical characteristic of the parabola and the way it may be built using its definition. all those lane sites whose distance from the directrix to the focus is equal.
Then, the focus must be at a distance of two units from the vertex, (0,0), in line with the parabola's axis of symmetry (x=0), and on the positive side of the y-axis (notice the directrix is on the negative side of the y-axis.
So, the focus of this parabola at the point (0, 2).

Answer:
18
Step-by-step explanation:
21 - 3 = 18
Numbers 1, 3, 5, 7 go down in 3s
Numbers 2, 4, 6, and 8 go down in 3s
If you need further explanation, let me know!
- profparis
Answer:
18
Step-by-step explanation:
Let's first find out the pattern
32-27 = 5
29 - 27 = 2
29 - 24 = 5
24 - 26 = 2
26 - 21 = 5
21 - 23 = 2
23 - 18 = 5
Pattern = Subtract 5 , Add 2
Since at 23 - 18 = 5
Therefore the next one is subtract 5
Hence, 23 - 5 = 18

The relative frequency of Event A in an experiment is 20%. If the experiment is performed 40 times, how many times should you expect Event A to occur?
Enter your answer as a number, like this: 42
Step-by-step explanation:
look at a die, for example.
the probabilty to roll a 6 is 1/6 (if all numbers truly have the same probability due to a perfectly balanced die).
so, you expect as a mean value that you have to roll the die 6 times to get one 6.
now in our general example :
20% = 1/5
so, we expect event A to happen once as a mean value every 5 attempts.
now we do 40 attempts. that means 8×5 sets of attempts.
and we therefore expect to see event A 8 times.

The roots of a quadratic equation are 4 and -5. Which quadratic equation has these roots?
Answer:
(x-4)(x+5) or x^2+x-20
Step-by-step explanation:
If a root of the function is 4, (meaning that when y=0, x=4) it can be rewritten as x-4.
The same goes for if a root is -5. it will simplify to x+5.
These are called factors of a quadratic equation.
Put together, they look like (x-4)(x+5). Using the FOIL method, that can be simplified to x^2+x-20
Answer:
Standard Form: [tex]y = x^2 + x - 20[/tex]
Factored Form: [tex]y = 1(x -4)(x +5)[/tex]
Step-by-step explanation:
Hello!
We can utilize the factored form of a quadratic to find the equation.
Factored Form of a Quadratic: [tex]y = a(x -h)(x - k)[/tex]
h and k are the rootsWe simply plug in the values of the roots and expand to find the equation. Replace "a" with 1.
Expand[tex]y = a(x +h)(x + k)[/tex][tex]y = 1(x -4)(x +5)[/tex][tex]y = 1(x^2 + x - 20)[/tex][tex]y = x^2 +x - 20[/tex]The quadratic equation [tex]y = x^2 + x - 20[/tex] has the roots 4 and -5.

John gave half of his stamps to Jim. Jim gave half of his stamps to Carla. Carla gave 1/4 of the stamps given to her to Thomas and kept the remaining 12. How many stamps did John start with?
Answer: 64 stamps
Step-by-step explanation:
Let the number of stamps John started with be J.
After giving half to Jim, he would have J/2 left.
After giving half to Carla he would have J/4 left and Carla would also have J/4.
After Carla gave 1/4 to Thomas, she would keep (3/4)*(J/4) = 3J/16 stamps. We are given that this equals 12.
Therefore, 3J/16 = 12
Multiply both sides by 16:
3J = 192
Divide both sides by 3:
J = 64

A. Translation
This type of translation is defined as moving the object in space by keeping its size, shape or orientation constant. In a translation, each point of the shape must be moved in the same direction and for the same distance. When you are doing a translation, the primary object is called the pre-image, and the object after the translation is called the image.
B. Rotation
This type of transformation has an object about a fixed point without changing its size or shape.
C. Reflection
A reflection is a transformation that reflects each point in the preimage across a line of reflection. It is a rigid motion so it preserves length and angle measure
A perpendicular bisector is a line (ray, segment) which cuts a line segment into two equal parts at90° angle
D. A transformation is a change in the position or size of an object Movements that do not change the size or shape of the object moved are called “rigid transformations” There are three types of rigid transformations: Translations, Reflections, and Rotations. These are more commonly referred to as Slides, Flips, and Turns.
Bob and Alice each have a bag that contains one ball of each of the colors blue, green, orange, red, and violet. Alice randomly selects one ball from her bag and puts it into Bob's bag. Bob then randomly selects one ball from his bag and puts it into Alice's bag. What is the probability that after this process the contents of the two bags are the same
Answer:
1/3
Step-by-step explanation:
Alice can select any ball from her bag and it goes into Bob's bag. Then bob has 6 balls including two of one color.
Suppose they are {A,B,B,C,D,E}
Now Bob must draw one of the two balls of the same color (B) in order to have the same content of the two bags.
P(bags same content)= 2/6= 1/3
The probability that the bags content are the same= 1/3
