Answer:

$180lb\ 12 oz - 79.3kg = 2.8kg$

Step-by-step explanation:

Given

$180\ lb 12\ oz - 79.3kg$

Required

Solve

First, convert 180lb to kg

$1lb \to 0.454kg$

$180lb \to 180 *0.454kg$

$180lb \to 81.7kg$ -- to 1dp

Next, convert 12oz to kg

$1oz \to 0.03kg$

$12oz \to 12 * 0.03kg$

$12oz \to 0.4kg$ --- to 1 dp

So, the expression becomes:

$180\ lb 12\ oz - 79.3kg$

$81.7kg + 0.4kg - 79.3kg$

$= 2.8kg$

Hence:

$180lb\ 12 oz - 79.3kg = 2.8kg$

after spending 1/3 of her money on a TV and 1/4 of it on a game console,Cindy still had $600 left. how much money did she spend

dmitriy555 [2]

Answer:

$360 on game console

$480 on tv

$1440 before spending money

x - 1/3x - 1/4x = $600

12/12x - 4/12x - 3/12x = $600

5/12x = $600

x = (12/5)($600)

x = $1440

Game Console = (1/4)(1440) = $360

Hope this helped!

Evaluate sin(36°), round your answer to four decimal places.

Mrrafil [7]

Answer:

$sin(36^{\circ})=\approx 0.5878$

Step-by-step explanation:

We are given that

$sin(36^{\circ)$

We have to find the value of $sin(36^{\circ)$

To find the value of $sin(36^{\circ)$ we will use table of sin

From sin table

We get

$sin(36^{\circ})$

=0.587785

We have to round off the answer to four decimal places

Therefore,

$sin(36^{\circ})=\approx 0.5878$

A particle is moving with the given acceleration function and initial conditions. Find the velocity function and the position fu

Lerok [7]

Answer:

The velocity function is the particle is $v(t)=-2\cos (t)-4\sin (t)-1$ .

Step-by-step explanation:

The acceleration function of a moving particle is

$a(t)=2\sin (t)-4\cos (t)$

The initial conditions are v(0) = −3, s(0) = 5.

Integrate the acceleration function with respect to time to find the velocity function.

$\int a(t)=\int (2\sin (t)-4\cos (t))dt$

$v(t)=-2\cos (t)-4\sin (t)+C_1$

Use the initial condition v(0) = −3 to find the value of C₁.

$-3=-2\cos (0)-4\sin (0)+C_1$

$-3=-2(1)-4(0)+C_1$

$-3=-2+C_1$

$-3+2=C_1$

$-1=C_1$

So the velocity function is the particle is

$v(t)=-2\cos (t)-4\sin (t)-1$

Integrate the acceleration function with respect to time to find the position function.

$\int v(t)=\int (-2\cos (t)-4\sin (t)-1)dt$

$s(t)=-2\sin (t)+4\cos (t)-t+C_2$

Use the initial condition s(0) = 5 to find the value of C₂.

$5=-2\sin (0)+4\cos (0)-(0)+C_2$

$5=-2(0)+4(1)+C_2$

$5=4+C_2$

$1=C_2$

So, the position function is the particle is $s(t)=-2\sin (t)+4\cos (t)-t+1$ .

A cafeteria serves lemonade that is made from a powdered drink mix. There is a proportional relationship between the number of s

ZanzabumX [31]

Therefore ,the constant of proportionality comes out to be 4 and the equation that represents the relationship is x=1/4y.

<h3>What is equation?</h3>

Since equations are essentially questions, efforts to systematically find answers to those questions have been the driving force behind the development of mathematics. From straightforward algebraic equations that just require addition or multiplication to differential equations, exponential equations that use exponential expressions, and integral equations, there are many different types of equations that range in complexity.

Here,

scoop is represented as x and water is represented as y

therefore, For every 2 scoops of mix, one half gallon of water is needed, and for every 5 scoops of mix, one and one fourth gallons of water are needed.

Equation from the given data is

2x = 1/2y or x=1/4y

and

5x = (1+1/4)y

5x=5/4y

So,

x=1/4y.

Therefore ,the constant of proportionality comes out to be 4

The equation that represents the relationship is x=1/4y.

We can graph the plot by using the given equation x=1/4y

or 4x=y

so for every x value we have to put 4 times its value into y for every point

you point in the graph.
