Answer:
5/12
Step-by-step explanation:
1/4 × 60 = 15
He gave 15 cakes to Helen.
He gave 20 cakes to Sue.
20 + 15 = 35
He gave away a total of 35 cakes.
60 - 35 = 25
He has 25 cakes left.
fraction = 25/60 = 5/12
Assuming that the given triangle is a right triangle where height and base are equal, we can solve for the missing variables. Let us review the given problem, the given is the total area since unit of "a" is inch squared.
The formula for an area of a triangle is At = 1/2(bxh). We substitute the given value and assume that h=b.
Therefore, 48=1/2bh. To eliminate 1/2, we multiply both sides by 2. Then we have 96=bh. When b=h, we have b^2=96.
The missing variables are b=h=9.8.
He would have to sale $500,000
9% of $500,000 is $45,000
So $30,000 plus $45,000 is $75,000
Answer: 8.3 feet
We know the area of 1 tile is:
(1)
We also know Jack used 103.75 tiles to cover the whole bathroom floor, which is a rectangle.
Remembering (1), we have that:
(2)
Which is also the area of the rectangle from which we only have the value of one of its sides, the width 
:
(3)
In addition, the area 
of a rectangle is given by the following equation:
(4)
Where 
is the length.
Substituting the value of the width written in (3) and the area (2) in equation (4):
(5)
We finally have the value of the length of the bathroom floor:
Answer:
Step-by-step explanation:
y = - 
x + 3 ( equation of line t )
y - (- 2) = - [ x - (- 2)] ⇒ y = - x - 
( equation of line u )
