16. Peter was told by his teacher that he needed to measure the height of the building in which his
classroom was located. He backs away from the building and places a mirror on the ground
between him and the wall. When he can see the top of the building in the mirror, Peter is 2 feet
9 inches away from the mirror and the mirror is 11 feet away from the wall of the building. Peter
knew his eye level was exactly 5 ft 6 inches off of the ground, so he was able to calculate the
height of the building. How tall is the building in feet?

Answer:

A

Step-by-step explanation:

Area of a base: 16 × 15 ÷ 2 = 120

Area of sides:

37 × 15 = 555

37 × 16 = 592

37 × 20 = 740

Area of prism: 2 × 120 + 555 + 592 + 740 = 2127

Answer: t=3.75

Step-by-step explanation:45=6t×2

6t=22.5

t=3.75

The object will take 3 seconds to fall 54 feet on Mercury according to the given function f(t) = 6t².

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

Given the function,

f(t) = 6t² where t is time in seconds while f(t) is the distance in feet.

At f(t) = 54 feet

6t² = 54

t² = 54/6 = 9

t = 3 seconds

Hence "The object will take 3 seconds to fall 54 feet on Mercury according to the given function f(t) = 6t²".

Answer:

you have a line with slope = -1/3. A line perpendicular to that has to have slope that's the negative reciprocal, or 3.

So we have a slope and a point. The line in point-slope form is

(y-3) = 3(x-4).

You can convert that to another form if you need to

any more help just ask :)

Answer:

y int is (0,5)

slope is m=-2

y=-2x+5

Step-by-step explanation:

The line has a slope of -2 and a y-intercept of y=4. (y=-2x+4)

Explanation: You can tell by where the line is landing on the x and y intercepts and it's as easy as counting lines. As far as the y-intercept goes, you can tell that by looking where the line crosses the y axis. And in this case it's (0,4) making your y-intercept, y=4.

Answer:

x+y = 87

1.5x+0.5y = 78.5

Step-by-step explanation:

Let x = number of nachos sold and y = number of sodas sold

x+y = 87 because that's the total number of nachos and sodas he sold

1.5x+0.5y = 78.5 because nachos cost $1.50 and sodas cost $0.50 and David made a total of $78.50

Answer:

x = 1

y = 6

Step-by-step explanation:

y = 6x   --------------(I)

7x - 8y = -41   ------------(II)

Substitute y =6x in equation (II)

7x - 8*(6x) = -41

7x - 48x    = -41   {Combine like terms}

     -41x = -41

          x = -41/-41

x = 1

Plug in x = 1 in equation (I)

y = 6*1

y = 6

Step-by-step explanation:

Answer:

Podemos determinar la velocidad del automóvil mediante diferencias sucesivas tanto en el dominio del tiempo como en el dominio de la posición:

Dominio del tiempo

[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex]

Dominio de la posición

[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex]

Step-by-step explanation:

En este caso, es necesario tener una función que represente a esta en función del tiempo o de la posición si nos basamos en las definiciones diferenciales de aceleración ([tex]a(t)[/tex]), medida en metros por segundo al cuadrado, es:

[tex]a(t) = \frac{dv}{dt}[/tex] (1)

[tex]a(s) = v(t)\cdot \frac{dv}{ds}[/tex] (2)

Donde:

[tex]v(t)[/tex] - Velocidad del automóvil, medida en metros por segundo.

[tex]\frac{dv}{dt}[/tex] - Primera derivada de la velocidad con respecto al tiempo, medida en metros por segundo.

[tex]\frac{dv}{ds}[/tex] - Primera derivada de la velocidad con respecto a la posición, medida en [tex]\frac{1}{s}[/tex].

A continuación, analizamos cada ecuación:

Eq. 1

Procedemos a despejar la diferencial de velocidad e integramos la expresión resultante:

[tex]v_{f}-v_{o} = \int {a(t)} \, dt[/tex] (3)

[tex]v_{f} = v_{o}+\int {a(t)} \, dt[/tex]

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex] (3b)

Eq. 2

Procedemos a despejar la velocidad e integramos la expresión resultante:

[tex]\int {v} \, dv = \int {a(t)} \, ds[/tex] (4)

[tex]\frac{1}{2}\cdot v_{f}^{2}-\frac{1}{2}\cdot v_{o}^{2} = \int {a(s)} \, ds[/tex]

[tex]\frac{1}{2}\cdot v_{f}^{2} = \frac{1}{2}\cdot v_{o}^{2}+\int {a(s)} \, ds[/tex]

[tex]v_{f}= \sqrt{v_{o}^{2}+2 \int {a(s)} \, ds }[/tex]

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex] (4b)

Answer:

1202.5  miles

Step-by-step explanation:

It is given that.

A test of a new car shows it can drive 370 miles on 20 gallons of gas.

We need to find how far you could drive on 65 gallons of gas.

20 gallons of gas = 370 miles

1 gallon = 18.5 miles

For 65 gallons of gas, multiply 65 and 18.5.

65 gallons = 18.5 × 65 miles

= 1202.5  miles

Hence, 1202.5  miles you could drive on 65 gallons of the gas.

Answer:

MO = 8 units

MP = 4 units

Step-by-step explanation:

[tex] In\: \triangle MOP, \\

\angle P = 90\degree ... (given) \\

\angle M = 60\degree ... (given) \\

\therefore \angle O = 30\degree(3^{rd} \: \angle \: of\: \triangle) \\

Let \huge\purple {MO = x \: units}... (1)\\

\therefore MP = \frac{1}{2} \times MO\\(side\: opposite \: to\: 30\degree) \\\\

\therefore MP = \frac{1}{2} \times x\\\\

\huge\red {\therefore MP = \frac{1}{2} x}.... (2)\\\\

\therefore PO = \frac{\sqrt 3}{2} \times MO\\(side\: opposite \: to\: 60\degree) \\\\

\therefore PO = \frac{\sqrt 3}{2} \times x\\\\

\huge\orange{\therefore PO = \frac{\sqrt 3}{2}x} \\\\

\because MP + PO + MO = P(\triangle MOP) \\\\

\therefore \frac{1}{2} x+\frac{\sqrt 3}{2}x+ x = 12+4\sqrt 3\\\\

\therefore \frac{1}{2} x+x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\

\therefore \frac{3}{2} x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\

\therefore \frac{(3+\sqrt 3)}{2} x= 4(3+\sqrt 3)\\\\

\therefore x = 4(3+\sqrt 3)\times \frac{2}{(3+\sqrt 3)}\\\\

\therefore x = 4\cancel{(3+\sqrt 3)}\times \frac{2}{\cancel {(3+\sqrt 3)}}\\\\

\therefore x = 4\times 2\\\\

\therefore x = 8\\\\

\huge\purple {\boxed{\implies MO = 8}} \: \\ [From\: equation \: (1)]\\\\

\because MP = \frac{1}{2} x \:

\\ [From\: equation \: (2)]\\\\

\therefore MP = \frac{1}{2} \times 8\\\\

Answer:

4.6%

Step-by-step explanation:

Cost of item __ sales tax

10 ___________0.46

50 __________ 2.30

5 ___________ 0.23

To obtain the sales tax % :

Sales tax % * cost of item = amount of sales tax

Let sales tax % = x

Using any of the rows in the table :

x * 10 = 0.46

x = 0.46 / 10

x = 0.046

x = (0.046) * 100% = 4.6%
