An aquarium holds 11.35 cubic feet of water, and is 2.8 feet long and 1.5 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
3 feet
Step-by-step explanation:
the volume of the aquarium is V= Lx wx H
it is as of now given that V=11.25 cubic feet, so 11.25=LxWxH
H tallness and it is the aquarium's profundity
H=11.25/L xW= 11.25/2.5x1.5= 3 feet
Answer:
The depth is 3 ft
Step-by-step explanation:
The equation for volume is V = length * height * depth
change the equation for depth
depth = volume / (length * height)
fill the equation and solve
depth = 11.35 / (2.8 * 1.5)
depth = 11.35 / 4.2
depth = 2.70238095 rounded to 3

What is the range of the function graphed below?
A. -∞ < y < -2
B. -∞ < y < ∞
C. -∞ < y < 2
D. -2 < y < ∞
Answer:
C
Step-by-step explanation:
The range is all the (y) values the function could have. The function's left end approaches negative infinity, while the right end approaches the asymptote of the function, y = 2.
So, the range is -∞ < y < 2. The answer is C.
I hope this helps :]
The range of the function is option (C) -∞ < y < 2 is the correct answer.
What is the range of a function?The range is the set of possible output values, which are shown on the y-axis. The range of a function, f is the set of all values f(x) , such that x is in the domain of f. Graphically speaking, the range is the set of all y such that (x,y) is a point on the graph of f .
For the given situation,
The graph shows the function that is plotted on x-y axis.
The curve of the function tends from x-axis beyond infinity.
It bends at y = 2 and moves towards y-axis beyond infinity.
Hence we can conclude that the range of the function is option (C), -∞ < y < 2 is the correct answer.

The perimeter of a rectangular painting is 364cm . If the length of the painting is 96cm, what is its width?
Answer:
The width would be 86cm
Step-by-step explanation:
Perimeter is (Width*2) +(Length*2)
Length is 96, multiply by 2 : 96*2 = 192
Subtract this from the total perimeter (364-192 = 172)
Divide this by 2 to get 1 width value (172/2 = 86)
86 cm

A drawing is 12 inches wide and 10 inches long. Joe wants to enlarge each side by a scale factor of 0.3. What will be the area of the dilation?
Answer:
Area of the dilation = 10.8 square inches
Step-by-step explanation:
Given the original dimension
Length = 12inches
Width = 10inches
If they are dilated by a factor of 0.3
New length = 0.3 * 12 = 3.6in
New width = 0.3 * 10 = 3in
Area of the dilation = 3.6 * 3
Area of the dilation = 10.8 square inches

Answer:
78%
Step-by-step explanation:
Ok to solve this we can write this as
80 = [tex]\frac{73+82+85+83+x}{5}[/tex]
We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%
Your grade is the average of all of your scores hence the divided by 5
We next multiply both sides of the equation by 5 to get
400 = 72+82+85+83+x
400= 322+ x
78 = x
He must get a 78% minimum on his next test to get 80%

An emergency fund is defined as a savings account that has a balance equal to at least two months' living
expenses. An article in a financial magazine claims that 80% of American adults do not have an emergency fund.
To investigate this claim, a financial advisor selects a random sample of 150 American adults and finds that 112 do
not have an emergency fund. The financial advisor would like to know if the data provide convincing evidence that
the true proportion of Americans who do not have an emergency fund is less than 80%. What are the appropriate
hypotheses for this test?
Answer:
a H I o p=0.80 vs. Ha less than 0.80, where P equals the true proportion of All American adults who do not have an emergency fund
The appropriate hypotheses for this test are:
H0: p ≥ 0.80
Ha: p < 0.80
We have,
The appropriate hypotheses for this test are:
Null Hypothesis (H0):
The true proportion of Americans who do not have an emergency fund is equal to or greater than 80%.
Alternative Hypothesis (Ha):
The true proportion of Americans who do not have an emergency fund is less than 80%.
Symbolically, the hypotheses can be represented as:
H0: p ≥ 0.80
Ha: p < 0.80
Where p is the true proportion of American adults who do not have an emergency fund.
To determine whether the data provide convincing evidence against the null hypothesis,
We can conduct a hypothesis test using a significance level (alpha) of 0.05.
If the p-value is less than alpha, we can reject the null hypothesis and conclude that the true proportion of Americans who do not have an emergency fund is less than 80%.
Thus,
H0: p ≥ 0.80
Ha: p < 0.80 are the appropriate hypotheses for this test.

+32t+4, where h(t) is the height (distance from the ground in feet) of the candies and t is the number of seconds the candies are in the air. Describe in a paragraph what the graph of this scenario would look like.
Answer:
A parabola opens downward with vertex at (1,20)
The function that models the height of bag of candies is
The graph of this function is a parabola that opens downward.
To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.
Factor -16 to get;
Add and subtract the square of half the coefficient of t.
Factor the perfect square trinomial:
The vertex is (1,20)
This means the maximum height after 1 second is 20 feet.

Kaitlyn opens an account with an initial deposit of $7,250. The account earns 10% interest compounded annually. What is the amount of interest earned after 18 months if no additional money is deposited or withdrawn?
Answer:
the interest earned amount is $1,114.251
Step-by-step explanation:
The computation of the interest earned is shown below:
But before that the future value is
= Present value × (1 + rate of interest)^number of years
= $7,250 × (1 + 0.10)^1.5
= $7,250 × 1.10^1.5
= $8,634.251
Now the interets earned is
= $8,634.251 - $7,250
= $1,114.251
Hence, the interest earned amount is $1,114.251

[tex]\sqrt{180}[/tex] and [tex]6\sqrt{5}[/tex]
Step-by-step explanation:
The easiest way to solve this problem is to look at all the simplified radicals on the right. Then un-simplify them by bringing the coefficients under the radical. If the radican (value under the radical) of the radical on the right is equal to the radican on the left, then the two radicals are equal.
To un-simplify a radical, one will square the coefficients and then multiply that value by the current radican of expression. The result is the un-simplified value of the radical.
