An equation is shown.
3.8+y=14.2
What is the value for x that makes the equation true?

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

(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°

Step-by-step explanation:

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

Step-by-step explanation:

Answer:

56 divided by 2 would be 28.

Step-by-step explanation:

[tex]\frac{56}{2}[/tex] is the same thing as half of 56, since two 28s added together is 56, which means [tex]\frac{56}{2}[/tex] is equivalent to 28.

Answer: V≈900 ft³

Step-by-step explanation:

Formula

V=πr²h

Given

r=5 ft

h=12 ft

Solve

V=πr²h

V=π(5)²(12)

V=π(25)(12)

V=300π

V≈300(3)

V≈900 ft³

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.

Integrals

units squared. And Tada, that is the same as the other answer!

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:

[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.

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.

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.

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:

We want to find the volume. In order to do this, we need to define:

Therefore, the formula for volume is: [tex]v = l \times w \times h[/tex]

Finally, 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].

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.

Answer:

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 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

Step-by-step explanation:

Surface area is the total area of all the surfaces of a shape. In order to calculate the surface area we need to consider each unique face individually.

The base of the pyramid is a square of side-length 5, and its area is 5×5=25

The side faces form an iscosoles triangle of height 10 and base length 5, its area is 10×5×=25.

The total surface area = Triangle +Triangle +Triangle +Triangle +Square = 25+25+25+25+25 = 125
