Question 1

$3 \frac{1}{3} Y=60 \\ \\ \frac{10}{3} Y=60 \\ \\ Y=\frac{60 \cdot 3}{10} \\ \\ Y=18$

Question 2

$\frac{11}{5}x=55 \\ \\ x=\frac{55 \cdot 5}{11} \\ \\ x=25$

Provide me three coordinate points for the following, given the Slope and Y-intercept. 5. Slope = 7/9, Y intercept = 12(give me

madam [21]

Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

$\begin{gathered} y=mx+b \\ \Rightarrow y=\frac{7}{9}x+12 \end{gathered}$

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

$\begin{gathered} x=9 \\ \Rightarrow y=\frac{7}{9}(9)+12=7+12=19 \\ x=18 \\ \Rightarrow y=\frac{7}{9}(18)+12=7(2)+12=14+12=26 \\ x=27 \\ \Rightarrow y=\frac{7}{9}(27)+12=7(3)+12=21+12=33 \end{gathered}$

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)

James buys 8 packages, each 20 mechanical pencils, and passes out 1/4 of then to his friends. Write and evaluate an expression t

Usimov [2.4K]

Answer:

the answer is 131 because if you multiply 20 by 8 is 190 then you divide 1/4 by 190 and you get 131

Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position

Anna007 [38]

Answer:

$v(3\,s) = 106.6\,\frac{ft}{s}$ , $v(15\,s) = -11\,\frac{ft}{s}$

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

$v(t) = -9.8\cdot t + 136$

Now, the velocities after 3 and 15 seconds are, respectively:

$v(3\,s) = -9.8\cdot (3) + 136$

$v(3\,s) = 106.6\,\frac{ft}{s}$

$v(15\,s) = -9.8\cdot (15) + 136$

$v(15\,s) = -11\,\frac{ft}{s}$
