Answer:
Based off of the calculations I did, I got 32 as the answer.
Step-by-step explanation:
Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.
So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.
10/6 * 19 = 31.666...
Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.
31.666... + 4/12 = 32.
Thus, Jason used 32 cans of paint in total.
She'll need to use 14 , 1/4 cups to make 3 1/2 cups
I’m assuming the 3 and 4 are exponents??
The answer is
2.1708 x 10^7
Answer:
The height of the triangle is 7cm and the base is 16cm
Step-by-step explanation:
First of all we have to know the formula to calculate area of a triangle
a = area = 56
b = base
h = heigth
a = (b * h)/2
we replace the known values and we make 2 equations
56cm² = (b * h)/2
b = h + 9cm
we replace b by (h + 9cm) in the first equation
56cm² = (h + 9cm * h)/2
56cm² * 2 = h² + 9h
0 = h² + 9h - 112cm²
we use bhaskara formula:
(-b (±) √
(b² - 4ac) ) / 2a
we replace with the known values
h = (-9 (±) √
(9² - 4*1*(-112) ) ) / 2*1
h = (-9 (±) √
(81 + 448) ) ) / 2
h = (-9 (±) √529) /2
h = (-9 (±) 23)/2
h1 = (-9 + 23) / 2
h1 = 14 / 2
h1 = 7
h2 = (-9 - 23) / 2
h2 = -32 / 2
h2 = -16
The height of the triangle is 7cm and the base is 16cm
