Answer:
Ms. Day bought 5 blankets and 4 pillows.
Step-by-step explanation:
Let denotes number of blankets and denotes number of pillows.
Blankets cost her $16 while pillows cost her $10 and Ms. Day spent a total of $120.
Divide this equation by 2.
Ms. Day bought 9 items.
Multiply this equation by 5.
Subtract from
Put in
Therefore,
Ms. Day bought 5 blankets and 4 pillows.
Answer:
47.6m.
Step by step solution:
Perimeter of a triangle = base + 2 . length____(1)
Area of a triangle = 1/2 . base . diagonal
108 = 1/2 . base . 15
multiplying both sides by 2:
216 = 15 . base
dividing both sides by 15:
base = 14.4m
But the diagonal divides the triangle into two
right angle triangles each with the same length (hypotenuse),base and diagonal(height).
Taking one right angle triangle:
And using pythagoras theorem;
length² = base² + diagonal ²
length² = 7.2² + 15²
Note: Base of each right angle triangle is 7.2 which would sum up to be 14.4 the base of the full triangle.
length² = 276.84
taking the square root of both sides:
length = 16.6m
Putting the values of the base and length into equation (1).
Perimeter of the triangle = 14.4 + 2 . 16.6
Note: We are dealing with the whole triangle
now hence the base is 14.4m.
Perimeter of the triangle = 14.4 + 33.2 = 47.6m.
Step-by-step explanation:
19 = -23+ 6(2 - p)
19=-23+12-6p
19=-11-6p
6p=-11-19
6p=-30
p= -5
