Answer:

x = 34 (btw my friend helped me with this one)

Step-by-step explanation:

X+(3X+r)+R=180 right? Basic math (r is the small angle that form up PSR with 3X, R is just angle SRP)

x+(3X+r)+R=180

Put that to aside, next we have (3x+r)+T=180(T being TSP) yes?

But T+4x also=180

=>4x+(3x+r)

Next we have 68+3x+R=180 (smaller triangle)

Now we have all that, cramp them all together

We have two equations 68+3x+R=180 and x+(3x+r)+R=180

But 4x=3x+r sooo

Now we have 68+3x+R=180 or 3x+R=180-68

And 4x+x+R=1800 or 5x+R=180

Use the formula that i dont know the name of and calculate

x= 34 and R=10 how to check? 3x+R+68=3*34+10+68=180

Answer:

34=x

Step-by-step explanation:

180-68 =112 so angle PQS is 112 4x-3x is x so PSQ is x and now you can do x +x + 112 = 180 2x-68 x=34

I probably got it wrong tho, so sorry if it is incorrect

Scientists determined that Antárticas average winter temperature was -34.44 degrees Celsius. The difference between this tempera

WITCHER [35]

Answer:

15 degrees.

Step-by-step explanation:

First, count from -34.44 degrees to 0 degrees which is (0 - 34.44)=34.44 counts

Next, you determine how many more counts you need to reach the 49.44 degrees ; that would be 49.44 - 34.44 = 15

Therefore, the Antarticas highest recorded temperature was 15 degrees.

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.2 cm. Use differentials to estimate the maxim

rjkz [21]

Answer:

Maximum volume error = ±540 cm³

Relative error = 0.02

Percentage error = 2%

Step-by-step explanation:

Relative error : The ratio of volume error to the total volume.

Percentage error: The product of relative error and 100.

The volume of a cube is = $side^3$

v =x³

Differentiate with respect to x

$\frac{dv}{dx} = 3x^2$

$\Rightarrow dv = 3x^2 dx$

Here are x = 30 cm and dx= ±0.2 cm

∴ dv = 3×(30 cm)² (±0.2 cm)

=±540 cm³

The volume of the cube = 30³ cm ³ = 27,000 cm³

Then the relative error

$=\frac{dv}{v}$

$=\frac{540 cm^3}{27,000 cm^3}$

= 0.02.

The percentage error

= (0.02×100)

=2%

Graph the system of equation on graph paper or in your calculator, y=−4/3x+4y=−2/3x−2

aleksklad [387]

Answer:

The lines intersect once at (2, −1).

A graphic solution to a system of equations is only as accurate as the scale of the paper or precision of the lines. At times the point of intersection will need to be estimated on the graph. When an exact solution is necessary, the system should be solved algebraically, either by substitution or by elimination.

Step-by-step explanation:

hope i helped
