You add both the numbers up and see what they get. Then you subtract that number from 180 since that is always what a triangle equals, therefore your answer is 39

All three angles on a triangle always equal 180°.

Example: 100°+40°+40°=180°

102+39=141°

180-141=39°

x = 39°

The number of bags of mulch you need to cover a planting area varies jointly with the area to be mulched (a) in sq ft and the de
Lena [83]

Answer:

  22 2/9

Step-by-step explanation:

When z "varies jointly" with x and y, it can be described by the formula

   z = kxy

Here, we have bags of mulch (n) varying jointly with area (a) and depth (d), both in feet. The given information can let us find the value of k.

  n = kad

  10 = k·(120)(1/4)

  10/30 = k = 1/3 . . . . . divide by the coefficient of k

Now, we can fill in the other values of interest.

  n = (1/3)·(200)·(1/3) = 200/9

  n = 22 2/9

You need 22 2/9 bags of mulch to cover 200 ft² to a depth of 4 inches.

_____

<em>Comment on the problem</em>

This problem requires the formula be written with both area and depth expressed in feet, yet it gives depth in inches. The formula can also be written using depth in inches. In that case, k = 1/36.

Tomtit [17]

Answer:

Norton's

Step-by-step explanation:

Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases

Whereas Norton's depot required 30% down payment on installment purchases.

1/3 is fractional value of 33.33%.

therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.

Answer:  Last one is right  C = 5 / 9 (F-32)

Step-by-step explanation: Solving  C from equation F = (9/5)C + 32 :

1. multiply by 5     you get   5F = 9C + 160  and 5(F-32) = 9C

2. divide by 9 you get (5/9) (F-32) = C
