Answer:

  20 longs, 9 units more than the 9 flats

Step-by-step explanation:

If Abby has 9 flats, she has 900 blocks of the 1109 she needs. The remaining 209 can be represented by ...

  20 longs

  9 units

_____

<em>Comment on the question</em>

We cannot see the model Abby has put together so far, so we don't know exactly what it takes to finish it. Any longs or units she already shows must be subtracted from the numbers above.

What is the median of the follow 6 scores ? 64 , 72, 85 , 80 , 72 , 89
bulgar [2K]

Answer:

76

Step-by-step explanation:

median is the number in the very center of the list of numbers in order:

64, 72, 72, 80, 85, 89

to find the one in the middle we take away the numbers from both ends:

72, 72, 80, 85

72, 80

since there are two numbers in the middle we’ll find the average

(72+80)/2

152/2

In a right triangle, Sin (30 + x) º = Cos (3x) º. What is the value of x?
pogonyaev

Answer:

x=15^\circ

Step-by-step explanation:

In a right triangle:

\sin \theta =cos(90^\circ-\theta) $ (Complementary angles)

Therefore, given:

Sin (30 + x) \º = Cos (3x) \º\\30+x+3x=90^\circ\\30+4x=90^\circ\\4x=90^\circ-30^\circ\\4x=60^\circ\\$Divide both sides by 4\\x=15^\circ

Which is the equation of Line B?
notka56 [123]
  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

\frac{1-2}{1-(-3)}=-\frac{1}{4}

Next, plug either one of the points into the x and y coordinates to solve for b as such:

2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b

<u>Our final equation is y=-\frac{1}{4}x+\frac{5}{4} , or the third option.</u>
