so

0.5+0.3=0.8 liters

Remember that

1 liter= 1,000 milliliters

so

0.8 liters=0.8*1,000=800 milliliters

Answer:

800 mL

Step-by-step explanation:

Because we know that

1 liter equals 1000 milliliters

So 0.5+0.3=0.8

Step-by-step explanation:

base area=18

18*15=270

The volume of the triangular prism is equal to [tex]270[/tex] cu. units.

" Volume is defined as the total space occupied by a three-dimensional object."

Formula used

Volume of a triangular prism = Area of the base × height

Area of the base [tex]= \frac{1}{2} \times base \times height[/tex]

According to the question,

Given dimensions,

Base of triangle [tex]= 9 units[/tex]

Height of the triangle [tex]=4 units[/tex]

Height of the triangular prism [tex]= 15 units[/tex]

Substitute the value in the formula to get the area of the base we have,

Area of the base [tex]= \frac{1}{2}\times 9\times 4[/tex]

                             [tex]= 18 square units[/tex]

Volume of a triangular prism [tex]= 18 \times 15[/tex]

                                                  [tex]= 270 cu.units[/tex]

Hence, the volume of the triangular prism is equal to [tex]270[/tex] cu. units.

Answer:

The correct option is A.

Step-by-step explanation:

We need to find the cheapest per month over all.

Assume a month has 30 days.

In option A:

Rent = 11.95 a day

Monthly rent = 11.95 × 30 = 358.5

Total renting amount is 358.5.

In option B:

Answer:

a) The length of the diagonal is 17.71 feet

b)  The area of the trapezoid is 123.14 feet²

Step-by-step explanation:

* Lets explain how to solve the problem

- Look to the attached figure

- ABCD is an isosceles trapezoid

∵ DC is the longer base with length 18 feet

∵ AD and BC are the two non-parallel sides with length 8 feet

∵ ∠ ADC and ∠ BCD are the bases angles with measure 75°

- AE and BF are ⊥ DC

# In Δ BFC

∵ m∠BFC = 90° ⇒ BF ⊥ CD

∵ m∠C = 75°

∵ BC = 8

∵ sin∠C = BF/BC

∴ sin(75) = BF/8 ⇒ multiply both sides by 8

∴ BF = 8 × sin(75) = 7.73

∵ cos∠C = CF/BC

∴ cos(75) = CF/8 ⇒ multiply both sides by 8

∴ CF = 8 × cos(75) = 2.07

# In Δ BFD

∵ m∠BFD = 90°

∵ DF = CD - CF

∴ DF = 18 - 2.07 = 15.93

∵ BD = √[(DF)² + (BF)²] ⇒ Pythagoras Theorem

∴ BD = √[(15.93)² + (7.73)²] = 17.71

a)

∵ BD is the diagonal of the trapezoid

* The length of the diagonal is 17.71 feet

b)

- The area of any trapezoid is A = 1/2 (b1 + b2) × h, where b1 and b2

  are the barallel bases and h is the height between the two bases

∵ b1 is CD

∴ b1 = 18

∵ b2 is AB

∵ AB = CD - (CF + DE)

∵ ABCD is an isosceles trapezoid

∴ CF = DE

∴ AB = 18 - (2.07 + 2.07) = 13.86

- BF is the perpendicular between AB and CD

∴ BF = h

∴ h = 7.73

∵ A = 1/2 (18 + 13.86) × 7.73 = 123.14

* The area of the trapezoid is 123.14 feet²

Answer:

y = - 3x + 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = - 3, hence

y = - 3x + c ← is the partial equation

To find c substitute (4, - 2) into the partial equation

- 2 = - 12 + c ⇒ c = - 2 + 12 = 10

y = - 3x + 10 ← equation of line

Answer:   [tex]y=-3x+10[/tex]

Step-by-step explanation:

The equation of a line in intercept form: [tex]y=mx+c[/tex]

The equation of a line passing through (a,b) and has slope m is given by :_

[tex](y-b)=m(x-a)[/tex]

Similarly, the  equation in slope-intercept form that describes a line through (4, -2) with slope -3 will be :_

[tex](y-(-2))=-3(x-4)\\\\\Rightarrow\ y+2=-3x+12\\\\\Rightarrow\ y=-3x+12-2\\\\\Rightarrow\ y=-3x+10\ \ \text{In intercept form}[/tex]

Hence, the equation in slope-intercept form that describes a line through (4, -2) with slope -3 = [tex]y=-3x+10[/tex]

Step-by-step explanation:

Answer:

53.4 and 62.6

Step-by-step explanation:

Got it right :/

Answer:

y = - 6x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{6}[/tex] x + 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{6}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{6} }[/tex] = - 6, hence

y = - 6x + c ← is the partial equation of the perpendicular line.

To find c substitute (- 3, 23) into the partial equation

23 = 18 + c ⇒ c = 23 - 18 = 5

y = - 6x + 5 ← equation of perpendicular line

To isolate the variable terms on one side and the constant terms on the other side of the equation 3x - 5 = -2 + 10, add 2 to both sides, simplify to 3x - 3 = 10, then add 3 to both sides to get the final simplified equation 3x = 13.

The equation 3x - 5 = -2 + 10 needs to be rearranged to isolate the variable terms on one side and the constant terms on the other. To do this, follow these steps:

Now, we have successfully isolated the variable terms (3x) on one side of the equation and the constant terms (13) on the other side.

To solve the system of equations x + 3y = 5 and x - 3y = -1, we add both equations to get 2x = 4, solve for x to find x = 2, and then substitute x back into one of the equations to find y = 1, resulting in the solution (2, 1).

The solution of the system of linear equations given by x + 3y = 5 and x - 3y = -1 involves manipulating the equations to find the values of x and y that satisfy both equations simultaneously. One common method to solve these is to add or subtract the equations, which eliminates one variable, making it possible to solve for the other.

Starting with the addition method, we align the equations and add them together:

x + 3y = 5

x - 3y = -1

Adding these equations, we get 2x = 4, and solving for x gives us x = 2. We can substitute x = 2 back into one of the original equations to find the value of y, yielding y = 1.

The solution to the system is the intersection point of the two lines represented by the equations, which is the point (2, 1).

The restriction on the domain of the function [tex]f(x) = {x + 5}/{x - 2}.[/tex] is that x cannot be equal to 2, since it would make the denominator zero, which is undefined in real numbers.

The student is asking to identify the restrictions on the domain of the function [tex]f(x) = {x + 5}/{x - 2}.[/tex] The domain of a function includes all the values that x can take for which the function is defined. In the case of a rational function, any values that make the denominator zero must be excluded from the domain since division by zero is undefined.

In this function, the denominator is x - 2. Therefore, the value that makes the denominator zero is x = 2. To identify the restrictions on the domain of [tex]f(x) = {x + 5}/{x - 2}.[/tex] we set the denominator equal to zero and solve for x:

Hence, the only restriction on the domain of this function is that x cannot be 2. So the domain of f(x) is all real numbers except x = 2.

Answer:

=$2739.81

Step-by-step explanation:

To find the total amount if the interest is compounded, we use the compound interest formula.

A=P(1+R/100)ⁿ

A is the amount, P- principal, is the invested amount R is the % interest rate, n is the number if periods.

If compounded semi-annually, it means we have two periods in 1 year

The rate is also divided by 2

Thus 25 years have (25×2) = 50 periods.

A= 750(1+5.25/200)⁵⁰

=750(1.02625)⁵⁰

=$2739.81

Step-by-step explanation:

Answer:

it must be 9

Step-by-step explanation:

it is a simple division.

To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.

Original equation:

y = 2x + 17

Switched:

x = 2y + 17

Solve for y by isolating it:

x - 17 = 2y + 17 - 17

x - 17 = 2y

(x - 17)/2 = 2y/2

[tex]\frac{1}{2}x-\frac{17}{2}= y[/tex]

Final answer:

The notation h(40)=1820 means that the function h produces an output of 1820 when the input is 40, although additional context is needed to determine what h represents specifically in this scenario.

Explanation:

The expression h(40)=1820 typically means that a function h is being evaluated at the input value of 40, and the output is 1820. This could represent a variety of contexts, such as the height of a rocket in meters at 40 seconds after launch, the amount of money saved after 40 weeks, or any other situation described by a function where the variable h depends on the number 40. Without additional context, it's impossible to say precisely what 1820 refers to, but it is the result of the function h when the input is 40.

Answer:

[tex]x_1 = 9[/tex] and [tex]x_2 = 11[/tex].

Step-by-step explanation:

Start by adding 1 to both sides of this equation.

[tex](x - 10)^{2} = 1[/tex].

The square of what number or numbers will lead to the number "1"? It turns out that not only [tex]1^{2} = 1[/tex], but [tex](-1)^{2}= 1[/tex] as well. In other words, the value [tex](x - 10)[/tex] can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.

Consider the case when [tex]x - 10 = 1[/tex]. Add 10 to both sides of the equation. [tex]x = 11[/tex].

Now, consider the case when [tex]x - 10 = -1[/tex]. Again, add 10 to both sides of the equation, [tex]x = 9[/tex].

Order the two solutions in an increasing order:

[tex]\bf a^3b^{-2}c^{-1}d\implies \cfrac{a^3d}{b^2c}\qquad \begin{cases} a=2\\ b=4\\ c=10\\ d=15 \end{cases}\implies \cfrac{2^3\cdot 15}{4^2\cdot 10}\implies \cfrac{120}{160}\implies \cfrac{3}{4}[/tex]

Answer:

10sqrt3+22

Step-by-step explanation:

Ok, let us imagine it as a sort of rectangle split upon its diagonal.

Using that, we can Pythag it out,

11^2+b^2=14^2

121+b^2=196

b^2=75

b=sqrt75

b=5sqrt3

Ok, using this info, we find the perimeter,

5sqrt3+5sqrt3+11+11

10sqrt3+22

The answer is 10sqrt3+22

The answer is:

The perimeter of the rectangle is equal to 39.32".

[tex]Perimeter=39.32in[/tex]

Since we are working with a rectangle, we can use the Pythagorean theorem to find the missing side of the rectangle and calculate its perimeter. We must remember that we can divide a rectangle into two equal right triangles.

According to the Pythagorean Theorem, we have:

[tex]a^{2}=b^{2}+c^{2}[/tex]

Where:

a, represents the hypotenuse of the triangle which is equal to the diagonal of the given rectangle (14")

b and c are the other sides of the triangle.

Now, let be "a" 14" and "b" 11"

So, solving we have:

[tex]a^{2}=b^{2}+c^{2}[/tex]

[tex]14^{2}=11^{2}+c^{2}[/tex]

[tex]14^{2}-11^{2}=c^{2}[/tex]

[tex]14^{2}-11^{2}=c^{2}\\\\c=\sqrt{14^{2} -11^{2} }=\sqrt{196-121}=\sqrt{75}=8.66in[/tex]

Now, that we already know the the missing side of the rectangle, we can calculate the perimeter using the following formula:

[tex]Perimeter=2base+2length\\\\Perimeter=2*11in+2*8.66in=22in+17.32in=39.32n[/tex]

Hence, we have that the perimeter of the rectangle is equal to 39.32".
