If the volume of a solid cone is 440cm3 and
its perpendicular height is 14cm. Determine
its base diameter to the nearest whole
number
O a. 5.5cm
b. 12cm
С. 6cm
d. 11cm
Answer:
11
Step-by-step explanation:
1/3 nr^2h = volume of a cone
1/3 x 22/7 x 14 x r^2 = 440
r^2 = 440 x 3 x 7/22 x 1/14
r^2 = 30
r = 30
r = 5
The base diameter to the nearest whole number is 11cm
The volume of a coneThe formula for calculating the volume of a cone is expressed as:
V =1/3πr²h
Given the folllowing parameters
V = 440cm^3
h = 14cm
Substitute the given parameters
440 = 1/3(22/7) * 14r²
440 = 44/3 * r²
10 = r²/3
r² = 30
r = 5.5cm
d = 11cm
Hence the base diameter to the nearest whole number is 11cm

A bookcase is 8 feet high, 1 foot deep, and 2 feet wide. How much space (in volume) does the bookcase take up?
Answer:
The volume of the bookcase is 16 cubic feet.
Step-by-step explanation:
Hey there!
We are given three values (in feet) and asked to find the volume of a bookcase:
8 feet high1 foot deep2 feet wideWe want to find the volume. In order to do this, we need to define:
the formula for finding the volume of a rectangular prismwhat values our data fits withTherefore, the formula for volume is: [tex]v = l \times w \times h[/tex]
[tex]v[/tex] - volume[tex]l[/tex] - length[tex]w[/tex] - width[tex]h[/tex] - heightFinally, we need to assign each number value to either the length, the width, or the height.
Wide is a synonym for width, so our width is 2 feet.
Deep is another way of saying the space inside of the bookshelf, which would be the length (1 foot).
High would refer to how tall something is, so the height is 8 feet.
Now, let's plug in our values and solve for [tex]v[/tex].
[tex]v = l \times w \times h[/tex][tex]v = 1 \times 2 \times 8[/tex][tex]v = (1 \times 2) \times 8[/tex][tex]v = 2 \times 8[/tex][tex]v = \text{16 cubic feet}[/tex]It's important to note that since we are finding volume, our measurement of feet becomes cubic feet.
Therefore, the volume of the bookcase is 16 cubic feet.
A portfolio is efficient if which of the following is true?
Answer:
In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.

What is the net signed area between f(x) = 2x + 3 and the x-axis over the interval (-4,2]? Do not include any units in
your answer
Provide your answer below:
Answer:
Step-by-step explanation:
2 units squared.
Explanation:
You can go about this in two ways: Algebra and Integrals.
Algebra
y = 2x-6 is linear, thus if we take the value over the x interval [2,4] we can use geometry to calculate the area.
graph{2x-6 [-2.27, 7.73, -2.18, 2.82]}
You can see two triangles in the graph (you could also find this algebraically). Thus, you can calculate the area.

Using integrals, it is found that the area of the function is of 6 squared units.
The area of a function f(x) over an interval [a,b] is given by:
[tex]A = \int_{a}^{b} f(x) dx[/tex]
In this problem:
Interval (-4, 2), thus [tex]a = -4, b = 2[/tex].Function [tex]f(x) = 2x + 3[/tex], thus:[tex]A = \int_{-4}^{2} 2x + 3 dx[/tex]
[tex]A = x^2 + 3x|_{x = -4}^{x = 2}[/tex]
[tex]A = 2^2 + 3(2) - [(-4)^2 + 3(-4)][/tex]
[tex]A = 4 + 6 - 4[/tex]
[tex]A = 6[/tex]
The area is of 6 squared units.

The perimeter of a triangle is 61 in. The shortest side is 8 in. less than the longest side. The middle side is 19 in. less than the combined lengths of the shortest and longest sides. Find the lengths of the three sides.
Answer:
since the lengths are consecutive odd numbers and the perimeter of the triangle is 51cms. Let x be the unknown length.
so 3x=51 ; x=17 . now the sides can be 15cms, 17cms, 19cms.
check Add them up it is 51cms which is the perimeter and the consecutive odd numbers
The population of a city is 40,000 and the annual growth rate is 1.6%. Write an equation to model the population y after x years.
Y=40,000(1.016)^x
Explanation:
years= x
Predicted population= y
Initial population= 40000
you can find the population y after x years with the help of this function
For example:
If we want to know the population after 5 years, put x=5 and find y
Y after 5 years= 40000(1.016)^5
=43304

(a) the given triangle is a isosceles triangle, therefore the two leg sides will be congruent, as well as the two base angles. It is given that one of the base angles ∠XYW is 70°, therefore, due to the law of a isosceles triangle, the measurement of ∠XWY is also 70°. Remember, a triangle's interior angles add up to 180°, so:
180 - (70 + 70) = 180 - 140 = 40
40° is your answer.
m∠X = 40°
(b) All sides are congruent, making it a equilateral triangle. If it is a equilateral triangle, then all the angles also have the same measurement. The total of the interior angle's measurement is 180°. Divide by the amount of angles, 3:
180/3 = 60
60° is your answer.
m∠V = 60°

how do you solve
7x - 4y = 10 ?
just seeing how to sole this equation
Answer:
this is a simultanious equation and u need one more equation to do it
Step-by-step explanation:
there are many answers if u dont have the second equation.
You can just substitute a number in x then find y
eg.
x= 12/7 , y =0.5
Answer:
1. 7 x - 4 y = 10. 7x−4y=10. Add 4y to both sides. Add 4y to both sides.
2. 7x=10+4y. 7x=10+4y. The equation is in standard form. The equation is in standard form.
3. 7x=4y+10. 7x=4y+10. Divide both sides by 7. Divide both sides by 7.
4. \frac{7x}{7}=\frac{4y+10}{7} 77x=74y+10 Dividing by 7 undoes the multiplication by 7.
