Answer: 22

Step-by-step explanation:

(7x+5) + (3x-5) + 90 = 180

10x + 90 =180

        -90   -90

10x          =90

Answer:

To find the missing angles of the triangle we must first make an equation using what we know. A triangles sum is equal to 180 degrees, and a box indicator represents a 90 degree angle. With that we do this,

(7x+5)+(3x-5)+90=180
7x+5+3x-5+90=180
7x+3x+90=180
10x+90=180
10x=180-90
10x=90
10x/10=90/10
x=9

Now we find each individual missing angle,

(3x-5)
3(9)-5
27-5
22 degrees

(7x+5)
7(9)+5
63+5
68 degrees

Check to make sure it equals 180 degrees

22+68+90=180

Write 5/6 - 7/9 in simplest form
DiKsa [7]

9514 1404 393

Answer:

  1/18

Step-by-step explanation:

18 is a suitable denominator for both fractions:

  5/6 = 15/18

  7/9 = 14/18

Then the difference is ...

  5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18

Kwame must earn more than 16 1616 stars per day to get a prize from the classroom treasure box. Write an inequality that describ
IrinaK [193]

The inequality that describes the number of stars S that Kwame must earn per day to get a prize from the classroom treasure box is: S > 16.

<h3>What is the inequality that models this situation?</h3>

The number of stars that he earns is represented by the variable S. He must earn more than 16 stars to earn a prize from the classroom treasure box, hence the inequality that represents the desired amount is given as follows:

S > 16.

Which is read as:

S is greater than 16, which is derived from the Fact that Kwame must earn more than 16 stars per day to get a prize, as stated in the problem.

A stone is thrown straight up from earth with D(t)= -4.9 t^2 + vt where D = height in meters, t= time in seconds, and v= initial
Vedmedyk [2.9K]

Answer:

(a)  D(t)= -4.9 t^2 + vt

(b) 10 sec

(c) 122.5m

(d) At t= 4sec, v= 9.8m/s (upwards) and at t= 9sec, v= 39.2m/s (downwards)

(e) -24.5m

(f) -49m/s (i.e. downwards)

(g) 0

Step-by-step explanation:

(b) Time in the air = 2v/g = 10sec

(c) Maximum height = \frac{v^{2} }{2g} =122.5m

(d) Velocity at any time t = v -9.8t

     So, at t= 4sec, velocity = 49 – 9.8(4) =9.8m/s

    at t= 9sec, velocity = 49 – 9.8(9) = -39.2m/s

(e) Average velocity = \frac{\int\limits^9_4 {v-9.8t} \, dt }{\int\limits^9_4 {1} \, dt } = -24.5m

(g) the stone is thrown vertically upwards, so no horizontal distance covered.
