Answer:
Step-by-step explanation:
Sting lights outlining the stage means that they will go around the perimeter, so we will need to find that. It gives us the area and the fact that the dimensions, length and width, will be whole numbers.
How do you find the area of a rectangle? you multiply length by width. So we need to find two numbers that multiply together to make 42. There re multiple pairs of numbers that do that, but the question is asking for what the least number of yards of string lights, so we need to find the values that make the perimeter the smallest.
Of course the perimeter is adding up all the sides. Since there are two lengths and two widths we can solve that like this
length + length + width + width
2* length + 2*width.
Now we just have to check all the options. What numbers multiply together to make 42?
2 and 21
6 and 7
14 and 3
Now we just have to check which gives the smallest perimeter
2*2 + 2*21 = 4 + 42 = 46
6*2 + 7*2 = 12 + 14 = 36
14*2 + 3*2 = 28 + 6 = 34
So the smallest perimeter is the second one, where one of the measurements is 6 yards and the other measurement is 7 yards. There's your answer.
Answer:
F 904.32in ^3
Step-by-step explanation:
first use find the radius, which is always half the diameter, in this case 6.
then use the formula, knowing the radius is 6
the cube the radius
multiple radius by 4/3
then multiply by pi
Answer:
a) Total weekly cost = $300
b) For Cassey to break even she has to sell 4 baskets
Step-by-step explanation:
Cost of electricity and rent in a week = $200
Cost of ingredients to make one dessert basket = $2.50
Total cost of making 40 dessert basket= 40*25
= $100
a) Cassey total cost in a week is $200 + $100
= $300
b) if each basket is sold at $25,the total selling price of 40 baskets will be $(25*40)
= $1000.
For Cassey to break even with the cost of production she has to sell y basket.
y = cost of producing 25 baskets / cost of selling 1 basket
y = 100/25
y = 4 baskets
X - 12 = 44
44 + 12 = 56
x = 56
I hope I helped!
