The lid will have a base area of 55 1/4 square inches. The long sides of the lid will each have an area of 17 square inches. The short sides of the lid will each have an area of 13 square inches. The total surface area of the lid will be 115 1/4 square inches.
So, for the base, you have w = 6.5 and l = 8.5. Area = 6.5 * 8.5 = 55.25 = 55 1/4.
For the long sides, you have l = 8.5 and h = 2. Area = 8.5 * 2 = 17
For the short sides, you have w = 6.5 and h = 2. Area = 6.5 * 2 = 13
For the total surface area, you have one base which is 55.25, you have two long sides which are 2 * 17 = 34, and you have two short sides which are 2 * 13 = 26. 55.25 + 34 + 26 = 115.25 = 115 1/4.
Answer:
The inequality is true.
Step-by-step explanation:
To show that it is true, you simply sub in 4 for x and 5 for y and see if the statement is true or not
7(4)-3(5) < 19
28-15 < 19
13 < 19

Unknown constant = x
x + 3x = 24
4x = 24
x = 6
No. of girls = 3 x 6 = 18
Answer:
The length of the missing leg is 56 meters.
Step-by-step explanation:
Use the Pythagorean theorem to figure out the leg of the missing leg.
Formula: a^2+b^2=c^2, given a=leg, b=leg, and c=hypotenuse
The hypotenuse is 65 meters, and one of the legs is 33 meters, so plug it into the formula and solve for a.
a^2+33^2=65^2
a^2+1089=4225
a^2=3136
Take the square root of both sides, and you get 56 meters.
