10+10+10=30 this might be right but i dont know
2(6*8)=96
2(6*3)=36
2(8*3)=48
96+36+48= 180 sq. in.
(The above is the answer to #2).I shouldn't give the answer to all of them, but I can explain how to do it. In order to calculate surface area, you need to find the area for all sides of the shape. For example, #2 has six sides, so you need to find the area for all six of those sides. There are two sides that are 8 x 3, two sides that are 6 x 8, and two sides that are 6 x 3. Therefore, your equation would be 2(8x3) + 2(6x3) + 2(6x8). From that you get 48+36+96 = 180 square inches (sq. in.)
Answer:
3. 35 adults and 420 children
4. The three numbers are 13, 52 and 16
Step-by-step explanation:
3. Let the number of adults be x.
Since there are 12 times more children than adults,
number of children= 12x
Total number of people= 12x +x
13x= 455
x= 455 ÷13
x= 35
12x= 35(12)
12x= 420
Therefore, there are 35 adults and 420 children at the play.
4. Let the first number be x.
Since the 2nd number is 4 times the first,
2nd number= 4x
Third number is 3 more than the first:
3rd number= x+3
sum of numbers= x +4x +x+3
6x +3= 81 (simplify)
6x= 81 -3 (bring constant to 1 side)
6x= 78 (simplify)
x= 78 ÷6
x= 13
Second number
= 4x
= 4(13) (subst. x=13)
= 52 (expand)
third number
= x +3
= 13 +3 (subst. x=13)
= 16
Answer:
Aircraft 1 has 194 seats, Aircraft 2 has 126 seats, and Aircraft 3 has 82 seats.
Step-by-step explanation:
In order to solve the present problem, an equation must be formulated. Thus, if the first aircraft has 68 seats more than the second one, and the third one has 44 fewer seats than the second aircraft, we can establish the following values:
Aircraft 1: X + 68
Aircraft 2: X
Aircraft 3: X - 44
Therefore, the equation could be stated as follows:
X + 68 + X + X - 44 = 402
3X = 402 + 44 - 68
3X = 378
X = 378/3
X = 126
So, Aircraft 1 will have 194 seats (126 + 68), Aircraft 2 will have 126 seats, and Aircraft 3 will have 82 seats (126 - 44).
