Answer:
The angles are 15 degrees, 45 degrees and 120 degrees
Step-by-step explanation:
The triangle has three three sides and three angles. The sum of the angles in a triangle is 180 degrees
Let x = the size of the largest angle of the triangle
Let y = the size of the middle angle of the triangle
Let z = the size of the smallest angle of the triangle.
x + y + z = 180 - - - - -- - - - - - - 1
The size of the largest angle is eight times the size of the smallest angle.
This means
x = 8z
The size of the middle angle is triple the size of the smallest angle. This means
y = 3z
Put x = 8z and y = 3z in equation 1
8z + 3z + z= 180
12z = 180
z = 180/12 = 15
x = 8z = 8×15 = 120
y = 3z = 3 × 15 = 45
Answer:
-2
Step-by-step explanation:
-9/3=-3
-3+b=-1
b=-1+3
b=-2
Amount times cost=profit
profit beverages=x times 1.26 or 1.26x
profit candy=y times 1.09 or 1.09y
the total profit is profit beverage plus profit candy or 1.26x+1.09y
they want total profit of 181.59
so
181.59=1.26x+1.09y is the answer in standard form
usually, we want whole numbers, but that's fine
Answer: he must pay $650 interest
Step-by-step explanation:
2000 x 0.650 x 1/2 = 650
1 ton= 2,000 pounds
STEP 1:
Multiply number of tons by 2,000 pounds
= 3 tons * 2,000 lbs/ton
= 6,000 lbs
STEP 2:
Add the extra pounds given (600 pounds) to calculated pounds in step 1
= 6,000 lbs + 600 lbs
= 6,600 pounds
ANSWER: 3 tons 600 pounds is equal to 6,600 pounds.
Hope this helps! :)
