Answer:
The area of the rectangle is 27
Step-by-step explanation:
so we need our formula to find the area of a rectangle. Area = Width × Length
Now we plug our numbers in.
A = 9 × Length
Since we are missing our exact Length amount we need to figure that out first. The statement says the length is 1/3 the size of the Width and the Width is 9.
9 × 1/3 = 9/3
9/3 can be simplified to 3 thus our Length is 3. now we add this into our equation
A = 9 × 3
A = 27
Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Step-by-step explanation:
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
The given are:
cost for each blog = $20
cost for each feature article = $60
blog = 10+2(number of articles sold)
total earnings = $700
where,
a = article
b = blog
to solve,
60(a)+20(10+2a)=700
60a+200+40a=700
200+100a=700
100a=700-200
100a=500
a=500/100
a=5
The total feature articles produced last week was 5.
to check,
a+b=700
60(5)+20[10+2(5)]=700
300+20(10+10)=700
300+200+200=700
700=700
Indeed, the number of articles produced last week was 5.
