Step-by-step explanation:

use the formula:

$v = u + at$

v = 30 [final velocity]

u = 10 [initial velocity]

a = 2 [acceleration]

solve for t [time]

Mickey and Donald earn $53 weekend after taxes Mickeys share is seven dollars greater than Donald's how much does Donald earn ea

igor_vitrenko [27]

Donald earns $23 each weekend and Mickey earns $30.

Step-by-step explanation:

Given,

Money earned by Mickey and Donald = $53

Let,

Share of Mickey = x

Share of Donald = y

According to given statement;

x+y=53 Eqn 1

x = y+7 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+7)+y=53\\y+7+y=53\\2y=53-7\\2y=46$

Dividing both sides by 2

$\frac{2y}{2}=\frac{46}{2}\\y=23$

Putting y=23 in Eqn 2

$x=23+7\\x=30$

Donald earns $23 each weekend and Mickey earns $30.

Find the value of x and the measure of each angle in the parallelogram

Morgarella [4.7K]

Answer:

$\angle D= 162\\\\\angle E = 18\\\\\angle F = 162\\\\\angle G = 18$

Step-by-step explanation:

By properties of parallelograms we know that opposite are the same so we have

$12x=4(x+3)\\\\4(3x)=4(x+3)\\\\3x=x+3\\\\2x=3\\\\x=\frac{3}{2}$

so for the angles we have

$\angle G=\angle E=12(\frac{3}{2})=18\\\\\angle D=\angle F = 180-\angle G=180-18=162$
