Um,
We know that the total interior angle in this parallelogram is 360° because there is the formula that help you with it:
180°(n-2) where n represent the total side of the figure, so
180°(4-2)
=180°(2)
=360°
Next, We see that angle L and angle N are equal with each other, and so angle O and M. Now, we have this equation:
(x+40°)+(x+40)°+(3x)°+(3x)°=360°
x°+40°+x°+40°+3x°+3x°=360°
8x°+80°=360°
Subtract 80° for both side
8x°+80°-80°=360°-80°
8x°=280°
x=35°
Angle O:
3x°
=3(35)°
=105°. As a result, angle O is 105°. Hope it help!

Jennifer paid $13.37 for a pack of 12 pairs of sport socks. What was the price of a pair of sport socks

alukav5142 [94]

Answer:

Each pair of socks cost around $1.11 excluding taxes.

Step-by-step explanation:

To find how much it costs for one pair of socks, divide the cost with how many pairs there are.

13.37/12 = 1.11426...

Since we are determining the cost of each pair of socks, it's only justifiable if we round it to the nearest hundredths.

Therefore, a pair of socks cost around $1.11 excluding taxes.

Can i get some help for this thanks

Alchen [17]

Answer:

∠A=125°

Step-by-step explanation:

Well since the lines are parallel, ∠B is opposite ∠A which means ∠B=∠A

$4x+45=6x+5\\45=2x+5\\40=2x\\2x=40\\x=20$

x=20°

Plugging x into the equation for ∠A.

$A=6*20+5\\A=120+5\\A=125$

∠A=125°

A recipe for beef stew calls for 1 pound of beef and 3 potatoes. The recipe is doubled to include 2 pounds of beef and 6 potatoe

vaieri [72.5K]

To answer the question, let B call the amount of meat and P the number of potatoes.

The recipe says that for every pound of meat we need 3 potatoes.

Then that relationship is written as follows:

$1B = 3P$

$\frac{1}{3}=\frac{P}{B}$

If we increase the amounts of the recipe by 100%, it will multiply by 2 the amount of meat and also that of potatoes. Therefore we need 2 pounds of meat and 6 potatoes.

Then the relationship is:

$2B = 6P$

$\frac{2}{6}=\frac{P}{B}$

But $\frac{2}{6}=\frac{1}{3}$

Therefore, the proportion that represents the situation remains the same $1B = 3P$

This occurs because the increase in the amount of potatoes and beef was in the same proportion.
