Answer:

w < -5.33333

Step-by-step explanation:

Step 1: Write inequality

12 < -1.5w + 4

Step 2: Solve for w

Here we see that any value smaller than -5.3333 will work.

Answer:

a)30-100/1000 • 120

Step-by-step explanation:

Given:

Remaining volume of fuel in a cars tank = I - E • D

where,

I = initial volume of fuel

E = fuel efficiency

D = distance traveled.

Carson

I = 30

E = 100

D = 120

Estimated volume of fuel in Carson's tank = I - E • D

= 30 - 100/1000 * 120

a)30-100/1000 • 120

Answer:

A (30-(100/1000)x120)

Step-by-step explanation:

I is a volume quantity, D is a distance quantity, and E is a rate measured as volume/distance.

So ExD gives us volume quantity.

Distance units are consistent (kilometers) but the volume units of E are inconsistent with those of I and the desired answer.

Let's convert E to liters per kilometer. We will use the fact that there are 1000 cubic centimeters per liter.

You get: 30 liter - 100/1000 liters/kilometer x 120 kilometers

In conclusion, this is the calculation that will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters:

30-100/1000x120.

Hope this helps!

Answer:

measure of angle ROQ is 41.5º

Step-by-step explanation:

That little curved line inside the angle POR and angle ROQ means they are congruent, or have congruent angles. So, we have two of the same angles, which we can represent with the same variable: x.

114-31= 83

83=2x

83/2 = 41.5

x=41.5

Answer:

1) x=√−y+5z or x=−√−y+5z

2) g=2x-4/x

Step-by-step explanation:

explanation for first problem:

Let's solve for x.

y=−x^2+5z

Step 1: Flip the equation.

−x^2+5z=y

Step 2: Add -5z to both sides.

−x^2+5z+−5z=y+−5z

−x^2=y−5z

Step 3: Divide both sides by -1.

−x^2

−1

=

y−5z

−1

x2=−y+5z

Step 4: Take square root.

x=√−y+5z or x=−√−y+5z

explanation for problem 2:

Let's solve for g.

gx=2x−4

Step 1: Divide both sides by x.

gx/x = 2x-4/x

g=2x-4/x

Answer:

The constant of proportionality is the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX. ... The constant of proportionality does is, the value of Y is dependent on how the given value of X is effected by the constant of proportionality.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Constant of proportionality means slope which can be represented as y=mx+b, y=kx and a ton of other stuff I don't know.

But lets take it as y=kx because it's easier. Constant of proportionality/slope is k so its C, 5.5.

For number 20:

Because a triangle is 180 degrees, we will equal all the angles we know to that. So, this is how we will write our equation:

Solve for x:

60 + x + 20 + 3x = 180

4x = 100

x = 20

Using 75, you can find the angle measure by plugging 75 where x is present in the angle measures. For example:

x = 20,

20 + 20 = 40

3(20) = 60

-

For number 21:

The shape shown is basically two triangles, so 180 x 2 is 360. Again, same procedure. Add all known angle measures and make an equation where they all equal 360.

Solve for x:

x-5+x+35+1.4x+x=360

x = 75

By isolating x, you should get an answer of 75. Now, plug that into each of the equations:

x = 75

75 + 35 = 110

75 - 5 = 70

1.4(75) = 105

Answer:

Question wasn't specific enough but I believe the cost=$93.92

Step-by-step explanation:

15.99*3=47.97

12.99*3=38.97

plus 1.99 and 4.99, add them all together

47.97+38.97+1.99+4.99=93.92

Answer:

x is approximately 69.39 degrees.

Step-by-step explanation:

To find x in this triangle, we can use the sin rule:

[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}[/tex]

The corresponding angle for each length is the one that lies directly opposite it. E.g. if 3.5 was our length 'a', then 55 degrees would be our angle A.

So let's take 3.5 and 55degrees as our length and Angle A, and 4 and x degrees as our length and angle B as we are trying to solve for x.

This would give us the following equation:

[tex]\frac{3.5}{sin(55)} =\frac{4}{sin(x)} \\[/tex]

Since we are solving for an angle, it will be easier to rearrange the equation if we have it as the numerator, so we can flip the fractions to make it easier. It will still be equal as we are looking for the ratio.

[tex]\frac{sin(55)}{3.5} =\frac{sin(x)}{4} \\[/tex]

From here let's isolate the sin(x) by multiplying by 4 and solving the values we have so far:

[tex]\frac{4 sin(55)}{3.5} =sin(x)\\\frac{3.2766}{3.5} =sin(x)\\0.936=sin(x)[/tex]

Now the final step is to use inverse sin to cancel the sin so we just have x:

[tex]sin^{-1} 0.936=x\\x=69.39[/tex]

x is approximately 69.39 degrees.

Hope this helped!
