Step-by-step explanation:

Answer:

x = 9°

Step-by-step explanation:

The full arc of the angles equals 360°. So, we can subtract all of the measures of angles we are given from the total 360 to find the value of x.

We can add the given angles together and subtract the sum from 360 as well.

73 + 63 + 89 = 225

This means the measure outside 15x is a combines 225°.

Now, subtract the known measures from our total, 360.

360 - 225 = 135

The unknown, or 15x, is equal to 135°.

15x = 135

Solve this like a normal equation. Divide both sides by 15 to isolate x and solve for the variable.

[tex]\frac{15x}{15}[/tex] = [tex]\frac{135}{15}[/tex]

x = 9

x is equal to 9°.

We can check by adding all our values together again to see if they amount to 360°.

73 + 63 + 89 + 15(9) = 360

360 = 360

The equation is correct, so we can be sure that we are right.

The answer is x = 9°.

Good luck ^^

Answer: should be x> -18

Step-by-step explanation: hope this helps

Answer:

x > -18

Step-by-step explanation:

8 > 2 - x/3

Multiply the equation by 3.

24 > 6 - x

Flip around to make working with it easier.

6 - x < 24

Subtract 6 from both sides.

-x < 18

Divide by -1. When dividing by a negative in an inequality, flip the sign.

x > -18.

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%

Equation of circle with center (h,k) and radius r: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Given: Radius = 5 , center = (0,4)

Eqation of circle: [tex](x-0)^2+(y-4)^2=5^2[/tex]

[tex]x^2+(y-4)^2=25[/tex]

[tex]x^2+(2.5x+4-4)^2=25[/tex]  [Using equation y = 2.5 x + 4  ]

[tex]x^2+(2.5x)^2=25[/tex]

Answer:

theanswer is D.72

Step-by-step explanation:

this.is because she blocked 36 balls in the first 4 games

As per the given data, it can predict that after 8 games the number of blocks would be 72 balls. Option c is correct.

Given that,
Based on these results, which is the most reasonable balls she will have blocked after 8 games is to be determined.

The average of the values is the ratio of the total sum of values to the number of values.

Here,
Average balls blocked in 4 games = 8 + 12 + 9 + 7 / 4 = 36 / 4
                                                          = 9
For the 8 games the number of ball blocked would be  = 8 × 9 = 72

Thus, as per the given data, it can predict that after 8 games the number of ball blocks would be 72 balls. Option c is correct.

Step-by-step explanation:

angles in a triangle add up to 180 degrees

the little squares in the corner mean its a right angle (90 degrees)

the two lines like in the op triangle mean the two angles downwards are the same.

angles in a semicircle add up to 180 degrees

3 lines mean all angles are the exact same

(Sorry i forgot 2 angles dont know which ones i forgot but with the info i gave you should be able to work those two out :)

slope = rise/run

rise = -3 ... move down 3 units

run = 4 .... move to the right 4 units

============================================

Work Shown:

m = slope

m = rise/run

m = (change in y)/(change in x)

m = (y2-y1)/(x2-x1)

m = (-17-(-2))/(24-4)

m = (-17+2)/(24-4)

m = -15/20

m = -3/4 is the slope

----------------

It basically means "move down 3 units, and move to the right 4 units"

So, slope = rise/run = -3/4

rise = -3 = move down 3 units

run = 4 = move to the right 4

You could express the slope as a decimal, and that would be -3/4 = -0.75, but you lose the rise and run values. So I recommend you keep the fraction.

Another problem with decimals is that sometimes we could have approximations that aren't exact. For example, if the slope was 2/3, then that approximates to 0.667 which may cause rounding errors down the line. Though I should point out that decimals do have their advantages in some cases.

i'm doing the activity rn and got it right

Answer:

the answer is d

Step-by-step explanation:

Here's the solution,

the opposite angles of parallelogram are equal, so, Angle G = Angle E

=》3x + 11 = 5x - 9

=》5x - 3x = 11 + 9

=》2x = 20

=》x = 10

value of x = 10

now, Angle G = 5x - 9

=》(5 × 10) - 9

=》50 - 9

=》41°

Angle G and Angle F are supplementary, so

=》 41° + Angle F = 180°

=》Angle F = 180° - 41°

=》Angle F = 139°

Answer:

6 got off at NJ

Step-by-step explanation:

if u write an equation it would be 44-x+2x=50. -x+2x=x so the equation would now be 44+x=50. If you subtract both sides by 44, it would be x=6. x was the number of people that got off at NJ so 6 people got off there.

Hope this helps!
