Answer:

38

38 38 38 38 38 38 38 38okay so all you're going to do 4 * 3 + 4 * 4 what is going to give you 12 +16

Kiran's age = x

Uncle's age = 54

Also,

Uncle's age = 8 + 3x

Now,

8 + 3x = 54

3x = 54 - 8

3x = 46

x = 46/3

x = 15.33

x = 15 (rounded)

Step-by-step explanation:

Answer:

f(3, -1) = 12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

f(x, y) = 2x - 3y + xy²

(3, -1) is x =3 and y = -1

Step 2: Evaluate

In (3,-1) the first number is x and the second number is y.

Replace x and y in the equation and solve:

2x - 3y + xy^2 = 2(3) -3(-1) + (3)(-1)^2

Simplify:

6 + 3 +3 = 12

The answer is 12

Answer:

w= 1

x = 6

Step-by-step explanation:

Congruent Triangles

When two triangles are determined to be congruent, their side lengths and angles have the same measure.

We are given the condition that triangles FGH and ABC are congruent. This implies that sides FH and AC have the same measure, or, equivalently:

x + 12 = 18

Solving:

x = 18 - 12 = 6

x = 6

Similarly, sides HG and CB have the same length, thus:

w + 45 = 46

Solving:

w = 46 - 45 = 1

w= 1

Answer:

  a) 96 m²

  b) 26,000 ft²

Step-by-step explanation:

The area of the unshaded region is the difference between the overall area of the rectangle and the area of the shaded region. It can also be found directly using the dimensions of the unshaded region.

a) We have the height of the right triangle, but need to know its base. The Pythagorean theorem can help with that. Let the base of the triangle be represented by x. Then ...

  x² +16² = 20²

  x² = 400 -256 = 144

  x = √144 = 12

The area of the unshaded triangle is given by the formula ...

  A = (1/2)bh

  A = (1/2)(12)(16) = 96 . . . . square meters

__

b) The shaded area at upper left is a square 100 ft on a side. Its area is ...

  A = s² = (100 ft)² = 10,000 ft²

The shaded area at upper right is a triangle with base and height 120 ft and 150 ft. Its area is ...

  A = (1/2)bh = (1/2)(120 ft)(150 ft) = 9,000 ft²

The area of the overall rectangle is ...

  A = LW = (300 ft)(150 ft) = 45,000 ft²

So, the unshaded area is ...

  unshaded area = overall area - left shaded area - right shaded area

  unshaded area = 45,000 ft² -10,000 ft² -9,000 ft² = 26,000 ft²

Answer:

No

Step-by-step explanation:

The triangles are not similar since triangle B has an angle (18 cm) that does not correspond to 10, unlike the other angles which you can get by multiplying 3/2.

The answer Is A. 6cm,8cm,10cm

Answer:

If you need an inequality here it is, can't really tell what you're trying to ask.

x-13≤15

Step-by-step explanation:

When we are talking about AT LEAST we are talking about the minimum.

For example, if I start a party and the age requirements for the party is at least 15, that means anyone who is 15 or older can enter the party.

So in your question, it says x reduced by 13 is at least 15, so reduced basically means to minus. So we are going to have x-13.

Then you have the "is at least 15". The at least is your sign for your inequality.

For example,

At least=≤

At most=≥

So the "is at least 15" is ≤15

Plug the numbers in: x-13≤15

Answer:

(x - 5) (x - 4)

x(x - 4) - 5(x -4)

x^2 - 4x - 5x - 20

x^2 - 9x - 20

Expand: x (x - 4) - 5 (x - 4)

Simplify: x^2 - 9x - 20

Answer:

16π

Step-by-step explanation:

Given that:

The sphere of the radius = [tex]x^2 + y^2 +z^2 = 4^2[/tex]

[tex]z^2 = 16 -x^2 -y^2[/tex]

[tex]z = \sqrt{16-x^2-y^2}[/tex]

The partial derivatives of [tex]Z_x = \dfrac{-2x}{2 \sqrt{16-x^2 -y^2}}[/tex]

[tex]Z_x = \dfrac{-x}{\sqrt{16-x^2 -y^2}}[/tex]

Similarly;

[tex]Z_y = \dfrac{-y}{\sqrt{16-x^2 -y^2}}[/tex]

∴

[tex]dS = \sqrt{1 + Z_x^2 +Z_y^2} \ \ . dA[/tex]

[tex]=\sqrt{1 + \dfrac{x^2}{16-x^2-y^2} + \dfrac{y^2}{16-x^2-y^2} }\ \ .dA[/tex]

[tex]=\sqrt{ \dfrac{16}{16-x^2-y^2} }\ \ .dA[/tex]

[tex]=\dfrac{4}{\sqrt{ 16-x^2-y^2} }\ \ .dA[/tex]

Now; the region R = x² + y² = 12

Let;

x = rcosθ = x; x varies from 0 to 2π

y = rsinθ = y; y varies from 0 to [tex]\sqrt{12}[/tex]

dA = rdrdθ

∴

The surface area [tex]S = \int \limits _R \int \ dS[/tex]

[tex]= \int \limits _R\int \ \dfrac{4}{\sqrt{ 16-x^2 -y^2} } \ dA[/tex]

[tex]= \int \limits^{2 \pi}_{0} } \int^{\sqrt{12}}_{0} \dfrac{4}{\sqrt{16-r^2}} \ \ rdrd \theta[/tex]

[tex]= 2 \pi \int^{\sqrt{12}}_{0} \ \dfrac{4r}{\sqrt{16-r^2}}\ dr[/tex]

[tex]= 2 \pi \times 4 \Bigg [ \dfrac{\sqrt{16-r^2}}{\dfrac{1}{2}(-2)} \Bigg]^{\sqrt{12}}_{0}[/tex]

[tex]= 8\pi ( - \sqrt{4} + \sqrt{16})[/tex]

= 8π ( -2 + 4)

= 8π(2)

= 16π

Answer:

[tex]e^t+e^{-4t}[/tex]

Step-by-step explanation:

We have to simplify the original function using partial fraction, hence:

[tex]\frac{5s}{s^2+3s-4} =\frac{5s}{(s-1)(s+4)}\\\\=\frac{A}{s-1}+\frac{B}{s+4}\\\\Therefore:\\\\\frac{A(s+4)+B(s-1)}{(s-1)(s+4)}=\frac{5s}{(s-1)(s+4)}\\\\Eliminating\ the \ denominator:\\\\A(s+4)+B(s-1)=5s\\\\substitute\ s=1:\\\\A(1+4)+B(1-1)=5(1)\\\\5A=5\\\\A=1\\\\tsubstitute\ s=-4:\\\\A(-4+4)+B(-4-1)=5(-4)\\\\-5B=-20\\\\B=4\\\\Therefore\ substituting\ A\ and\ B\ gives:\\\\\frac{5s}{s^2+3s-4}=\frac{1}{s-1}+ \frac{4}{s+4}\\\\[/tex]

[tex]From\ Laplace\ inverse:\\\\But\ L^{-1}[\frac{1}{s-a} ]=e^{at}\\\\Hence:\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]=e^{t}+4e^{-4t}\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=e^{t}+4e^{-4t}[/tex]

Answer:

If Abraham divides them into 2 separate groups, he should have 17 marbles on each group.

Step-by-step explanation:

Answer:

900

Step-by-step explanation:

Each group of 3 starred angles plus the 4th angle which is an interior angle of the triangle has a total measure of 360 degrees. The sum of the measures of the three angles of the triangle is 180 degrees.

total measure of the starred angles = 4 * 360 - 180

total measure = 900 degrees

Step-by-step explanation:

6|4w + 2| - 2 > 10

6|4w + 2| > 12

|4w + 2| > 2

4w + 2 > 2 or 4w + 2 < -2

4w > 0 or 4w < -4

w > 0 or w < -1.

The correct graph is the 2nd option.
