Misha and her cousin Darius made muffins for the Clark family reunion. Misha made 17 more muffins than Darius. Dark is made 56 m

VMariaS [17]

Answer:

Number of muffins per plate.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of muffins made by Dark

Then, number of muffins made by Misha =

$x + 17$

For x = 56

Muffins made by Dark = x = 56

Muffins made by Misha =

$x + 17 = 56 + 17 = 73$

Total number of muffins =

$56 + 73 = 129$

Total number of plates = 12

Number of muffins on each plate =

$=\dfrac{\text{Total number of muffins}}{\text{Total number of plates}}=\dfrac{129}{12} = 10.75\approx 11$

Thus, there were approximately 11 muffins on each plate.

Thus, the unit of this problem is number of muffins per plate.

An object falls from a position of rest and

kumpel [21]

Answer:

About 4.1323 meters.

Step-by-step explanation:

We can use the following kinematic equations:

$\displaystyle v_f = v_0 + at \text{ and } \Delta d = v_0 t + \frac{1}{2} at^2$

We want to determine the distance the object has dropped after falling from rest and reaching an instantenous speed of 9 m/s.

We are given that the acceleration due to gravity is 9.8 m/s².

Using this fact and the first equation, find the time for which it took the object to reach 9 m/s. Note that the initial velocity is 0 m/s since the object started from rest.

$\displaystyle \begin{aligned} v_f = v_0 + at \\ \\ (9\text{ m/s}) & = (0\text{ m/s}) + (9.8\text{ m/s$^2$})t \\ \\ 9\text{ m/s} & = (9.8 \text{ m/s$^2$})t \\ \\ t &\approx0.9184 \text{ s} \end{aligned}$

To find how far the object dropped, we can use the second equation:

$\displaystyle\begin{aligned} \Delta d & = v_0 t + \frac{1}{2} at^2 \\ \\ & = (0\text{ m/s})(0.9184 \text{ s}) + \frac{1}{2}(9.8 \text{ m/s$^2$})(0.9184 \text{ s})^2 \\ \\ & = 4.1323 \text{ m} \end{aligned}$

In conclusion, the object would have dropped about 4.1323 meters.

Solve the following equation for x.<br>m (2-x)=3-y

Evgesh-ka [11]

Answer: m=−y+3−x+2

x=2m+y−3m

Step-by-step explanation:

m(2−x)=3−y

Step 1: Factor out variable m.

m(−x+2)=−y+3

Step 2: Divide both sides by -x+2.

m(−x+2)−x+2=−y+3−x+2

m=−y+3−x+2

__________________________________________________

m(2−x)=3−y

Step 1: Add -2m to both sides.

−mx+2m+−2m=−y+3+−2m

−mx=−2m−y+3

Step 2: Divide both sides by -m.

−mx−m=−2m−y+3−m

x=2m+y−3m
