What are the remaining angle measures if the figure is to be a parallelogram?

goldfiish [28.3K]

The correct answer is

m∠B ==101°,

m∠C =79°,

m∠D=101°

Step-by-step explanation:

As we know that, it is a parallelogram opposite angels are congruent
Therefore, m∠A = m∠C and m∠B =m∠B

As we know that, If side a=79 then side c must also be equal to 79

When we consider all the angles and add them it must be equal to 360°
When we add 79+79 = 158°, which mean a=c= 158°

By subtracting all the sides of parallelogram which is 360- 158= 202°
If we divide it by 2 then we will get the value of the other side of the angle which is b and d.
Dividing 202 by 2
$\frac{202}{2}$ = 101°
Therefore, the value of b=d=101°
A Parallelogram is a flat shape with an opposite sides parallel and they are equal in length.
A parallelogram has four sides, and the opposite sides are parallel and they don't intersect.

Question isn't well formatted :

If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.

Answer:

0.7917

Step-by-step explanation:

If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

Given that :

Total number of cards = 48

Number given to friend = 10

Number of cards left = 48 - 10 = 38

Number of cards left / original number of cards

38 / 48

= 0.7917

3. MaxProfit Inc, a profit maximizing firm in a competitive market is currently producing 1000 units of widgets. It has average

Ivenika [448]

Answer;

Total profit is $18000

Step-by-step explanation:

Given in question

Number of unit is 1000

Average revenue is $100

Average total cost is $80

Fixed cost is $2000

Total revenue = average revenue $\times$ number of unit

Total revenue = $100 $\times$ 1000=$100000

Total input cost = total cost + fixed cost

Total cost = average cost $\times$ total unit

Total cost =$80 $\times$ 1000 = $80000

Total input cost = $80000 + $2000 = $82000

Profit = total revenue-total cost

Profit = $100000 - $82000 = $18000

Total profit is $18000

Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. What equations can be used to find the number of each of bal

fredd [130]

We can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon for Myer

SOLUTION:

Given, Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. We have to find what equations can be used to find the number of each of balloon in a bunch of 18 balloons that costs $19?

Let number of myers balloons be m, and number of latex balloons be n.

Then m + n = 18 ⇒ (1)

And according to given information,

$1.25 x number of myers ballons + $0.75 x number of latex balloons = $19

⇒ 1.25m + 0.75n = 19 ⇒ (2)

Hence, we can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon.

Now, (1) ⇒ m = 18 – n. substitute these values in (2)

(2) ⇒ 1.25(18 – n) + 0.75n = 19

22.5 – 1.25n + 0.75n = 19

1.25n – 0.75n = 22.5 – 19

0.5n = 3.5

n = 7

Then, m = 18 – 7 ⇒ m = 11.

So, 11 myers balloons and 7 latex balloons.
