Answer:
298 cm^2.
Step-by-step explanation:
There are 3 pairs of faces of equal area.
Area of top = 7 * 11. So it's 2 * 7 * 11 = 154.
Area of a smaller side = 7 * 4 so we have 2*28 = 56 .
Area of larger side = 4*11 so it's 2*44 = 88.
Total surface area = 154 + 56 + 88
= 298.
Answer:
.84
Step-by-step explanation:
Answer:
Logan - 7 hours
Sarah - 6 hours
Step-by-step explanation:
Given Logan can iron 40 shirts per hour, and Sarah can iron 35 shirts per hour.
Also given that they worked together a combined hours of 13 hours
Let the number of hours worked by Logan is x and the number of hours worked by Sarah be y hours
Given x + y = 13
Also given that they together ironed 490 shirt's
which means 40x + 35y = 490
solve the above two equations by elimination
Multiply the first equation with 35 and subtract from the second equation we get
40x - 35x = 490 - 455
5x = 35
x = 7 hours
Substitute this value in the first equation to get the values of y
x + y = 13
y = 13 - x
y = 13 - 7 = 6 hours
therefore the number of hours worked by Logan is 7 hours and the number of hours Sarah worked is 6 hours
there are 3 teaspoons in one tablespoon then 4 bottles have a combined total of 4 tablespoons.
if you have 3 teaspoons in one bottle and you have 4 bottles that will make 12 teaspoons, for every 3 teaspoons it is equal to one tablespoon. so you divide 3 into 12 which will make 4 tablespoons.
your is no
