find the value of x and round

Answer:

Step-by-step explanation:

Step 1: Calculate the slant height of the pyramid.

Slant Height = √(6.9^2 + 8^2) = 10.1 cm

Step 2: Calculate the lateral surface area of the pyramid.

Lateral Surface Area = 4 * (1/2 * 6.9 * 10.1) = 176.5 cm^2

Step 3: Calculate the total surface area of the pyramid.

Total Surface Area = Lateral Surface Area + Base Area

Total Surface Area = 176.5 cm^2 + (1/2 * 6.9 * 8) = 227.7 cm^2

Step-by-step explanation:

If Gavin's mother poured 1 cup of milk in the glass and Gavin drinks 1/5 of the milk, the fraction of the milk that will remain in the glass is (4/5) of 1 cup.

So, B ( 7/20) is the right answer.

Answer:

Part A -   Option B   $382.50

Part B -   11 years

Step-by-step explanation:

The formula for simple interest is

[tex]A=P(1+rt)[/tex]

[tex]A[/tex] is the final amount

[tex]P[/tex] is the initial amount

[tex]r[/tex] is the interest rate as a decimal

[tex]t[/tex] is the time

We are given

[tex]P=3000\\r=0.0425[/tex]

Part A

To evaluate the amount of interest we need to use this equation

[tex]I=Prt[/tex]

[tex]I=3000*0.0425*3[/tex]

[tex]I=382.5[/tex]

Part B

We can start with this equation, but we need to solve for [tex]t[/tex].

[tex]A=P(1+rt)[/tex]

Lets solve for [tex]t[/tex].

Divide both sides of the equation by [tex]P[/tex].

[tex]\frac{A}{P} =1+rt[/tex]

Subtract 1 from both sides of the equation.

[tex]\frac{A}{P}-1 =rt[/tex]

Divide both sides of the equation by [tex]r[/tex].

[tex]\frac{\frac{A}{P}}{r}-\frac{1}{r}=t[/tex]

Simplify the first term by multiplying the numerator by the reciprocal of the denominator.

[tex]\frac{A}{Pr} -\frac{1}{r}=t[/tex]

[tex]t=\frac{A}{Pr} -\frac{1}{r}[/tex]

Now we have an equation for time.

Substituting our values into the equation gives us

[tex]t=\frac{4402.50}{3000*0.0425} -\frac{1}{0.0425}[/tex]

[tex]t=11[/tex]

The radius of the cylinder with a combined volume of 1000 cubic inches is 2.4 inch

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let r represent the radius of the cylinder/cone.

For the cylinder:

Volume = π * radius² * height

but height is twice the radius, height = 2r, hence:

Volume = π * r² * 2r = 2πr³

For the cube:

Volume = side³

but side is four times the radius, side = 4r, hence:

Volume = (4r)³ = 64r³

The combined volume of a cube and a cylinder is 1000 cubic inches, hence:

1000 = 2πr³ +  64r³

r³(2π + 64) = 1000

r³ = 1000/(2π + 64)

r³ = 14.228

r = 2.4 inch

The radius is 2.4 inch

The graph of the equation x^2-x-2=3 is a parabola which opens downward.

An equation is a mathematical statement that expresses the equality of two expressions. It consists of two expressions separated by an equals sign (=). Equations are used to express relationships between unknowns, knowns, and constants. Equations are used to solve problems and describe the behavior of systems.

The graph intersects the x-axis at two points, x=1 and x=3.

Therefore, the solutions to the equation are x=1 and x=3.

To find an estimate of the solution, we can draw a straight line from the x-axis to the point of intersection on the parabola.

The line intersects the x-axis at a point slightly higher than x=1, so the estimated solution is x=1.5.

The amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.

What is integration ?

Integration is the process of finding an antiderivative of a function. An antiderivative of a function is a function whose derivative is equal to the original function. In other words, integration is the reverse process of differentiation. The process of integration can be thought of as the summing of an infinite number of infinitesimal "slices" of the function being integrated, over a given interval. The symbol ∫ is used to denote integration.

The amount of snow that falls between time t = 0 and time t = 5 hours can be found by evaluating the definite integral of the rate of snowfall with respect to time over the interval [0, 5].

∫[0,5] 2e^(-0.1t) dt

The antiderivative of 2e^(-0.1t) with respect to t is -20e^(-0.1t)

Therefore, the definite integral is

-20e^(-0.15) - (-20e^(-0.10))

= -20e^(-0.5) + 20 = 20(1-e^(-0.5))

Therefore, the amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.

So, originally the pail had 3.68L from the finished bottle

x+3.68L=y

Then the second equation is after Bill spills 1.2L from the pail, the contents are 3 times that of the bottle

y-1.2L=3x

then played first

so

x-y = -3.68

-3x+y= 1,2

-2x= -2.48

x=1.24L

So the volume of the bottle is 1.24 L

Pail volume: 1.24+3.68= 4.92L

The system of linear equations y = x - 6.7 and y = - x + 1.7 have solution at point (x, y) = (4.2, - 2.5).

In this problem we need to construct a system of two linear equations whose solution is point (x, y) = (4.2, - 2.5). Linear equations are algebraic equations of the form:

y = m · x + b

Where:

The procedure is shown below. First, obtain the intercept of the first equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = 1)

b = - 2.5 - 4.2

b = - 6.7

Second, write the first linear equation:

y = x - 6.7

Third, find the intercept of the second equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = - 1)

b = - 2.5 - (- 1) · (4.2)

b = - 2.5 + 4.2

b = 1.7

Let us assume that,

→ missing number = x

In the ΔWXY, with the incenter of the triangle being Z.

1. The measure of m∠WYZ = 43°.

2. The measure of m∠WXY = 66°.

3. The measure of m∠YWX = 28°.

4. The measure of m∠ZWX = 14°.

What is an incenter?

The intersection of the triangle's three interior angle bisectors forms the triangle's incenter. Due to the junction point of the central axis being the centre of the triangle's inscribed circle, this point is equally spaced from the sides of a triangle.

In ΔWXY, the incenter of the triangle is Z.

This means that ∠W, ∠Y and ∠X are equally bisected angles.

It is given that the measurement of ∠WYX = 86° and ∠WXZ = 33°

1. The measure of angle ∠WYZ.

The angle ∠WYX is bisected by the line segment YZ.

It forms two angles ∠WYZ and ∠XYZ.

So, the measurement of ∠WYZ = ∠WYX/2

∠WYZ = 86°/2

∠WYZ = 43°

Therefore, the measurement of ∠WYZ = 43°.

2. The measure of angle ∠WXY.

The angle ∠WXY is bisected by the line segment XZ.

It forms two angles ∠WXZ and ∠ZXY.

The measurement of angle ∠WXZ = 33°.

So,  the measurement of ∠WXY = ∠WXZ × 2

∠WXY = 33° × 2

∠WXY = 66°

Therefore, the measurement of ∠WXY = 66°.

3. The measure of angle ∠YWX.

According to the properties of the triangle, the sum of three angles of triangle is 180°.

So, the equation will be -

∠YWX + ∠WXY + ∠XYW = 180°

∠YWX + 66° + 86° = 180°

∠YWX + 152° = 180°

∠YWX = 180° - 152°

∠YWX = 28°

Therefore, the measurement of ∠YWX = 28°.

4. The measure of angle ∠ZWX.

The angle ∠YWX is bisected by the line segment WZ.

It forms two angles ∠YWZ and ∠ZWX.

So, the measurement of ∠ZWX = ∠YWX/2

∠ZWX = 28°/2

∠ZWX = 14°

Therefore, the measurement of ∠ZWX = 14°.
