answer: 27.9 pounds
work: the question is asking how many pounds he bought total, so add the potato and the carrots, and you have your answer. 24.37 + 3.53 = 27.9
The answers are the base represents the multlicative rate of change and the domain is all real numbers.
Since it is about only the outer part of the aquarium which is made of glasses we need to calculate the total surface area.
Surface area of the base = 4*3 = 12 square feet
Surface area of the shorter length of wall = 3*2 = 6 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
6*2 = 12 square feet
Surface area of the longer length of wall = 4*2 = 8 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
8*2 = 16 square feet
Therefore the total surface area that need to be covered with glasses
12+12+16 = 40 square feet
Answer: 10 inches.
Step-by-step explanation:
We have to solve a system of equations.
The formula to calculate a triangle area is A = (b.h)/2
where b is the base and h is the height. This will be our first equation.
Since the height is 4 inches greater than the base, the second equation will be: h = b+4
We replace h and the value of the area (70 square inches) in the first equation, and we solve it by using the cuadratic equation formula:
70 = (b . (b+4)) / 2
70 . 2 = b² + 4b
140 = b² +4b
0 = b² + 4b - 140
The roots of this polynomial are -14 and 10. Since a distance can't be negative, the length of the base is 10 inches.
Answer:
$38.64/4 = $9.66
its $9.66 for each yard
so $9.66 multiplied by 6 = $57.96
she should expect to pay $57.96 extra.
