Answer:
67
Step-by-step explanation:
DM=JM-JD=84-17=67
A box of donuts would cost: b = 3.84 + 0.18f
First, we have to find the total cost of the donuts.
12 x 0.32 = 3.84
Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.
So our equation could be: b = 3.84 + 0.18f (where f is the surface area of the box in square feet)
Answer:
x = 465 km
y = 735 km
Step-by-step explanation:
Step 1: Write out equations
x + y = 1200
y = x + 270
Step 2: Find <em>x</em> using substitution
x + (x + 270) = 1200
2x + 270 = 1200
2x = 930
x = 465
Step 3: Plug in <em>x </em>to find<em> y</em>
y = 465 + 270
y = 735
Answer:
61° , 151° , 12°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 29° + 90° = 180°
∠ 1 + 119° = 180° ( subtract 119° from both sides )
∠ 1 = 61°
-------------------
∠ 2 and 29° are adjacent angles on a straight line and sum to 180° , then
∠ 2 + 29° = 180° ( subtract 29° from both sides )
∠ 2 = 151°
----------------------
Using sum of angles in a triangle = 180°
∠ 3 + 17° + 151° = 180°
∠ 3 + 168° = 180° ( subtract 168° from both sides )
∠ 3 = 12°
