The answer is 45! A triangle measures 180 in total so add all those three angles to get 180.
Answer:
A: 8x-12
B: 5(n+3)
Step-by-step explanation:
A) Distribute 4 to the numbers inside the parenthesis.
4 x 2x= 8x
4 x -3= -12
8x-12
B) 5 is divisible to 15, so you can divide it with both numbers.
5/5=1
15/5=5
5(n+3)
Answer:
6m
Step-by-step explanation:
The area of the rectangular plot is
A = l*w
= 4*9
= 36 m^2
To find the area of the square plot
A = s^2
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 = s
The length of the side of the square plot is 6 m
Losing 30% of its value is the same as saying it is now worth 70% of its original value. To find 70% of 50,000 you can do 50,000 x 0.7. The answer will be the new value of the car after one year. After two years you are essentially finding 70% of the new value which is 70% of the original. More simply, it is 50,000 x 0.7 x 0.7. An equation for this (and the answer to 1b) is 50,000 x 0.7^t where t is the number of years.
1a (i) is $10500 (50,000 x 0.7^1)
(ii) is $2521.05 (50,000 x 0.7^5)
(iii) is $1412.38 (50,000 x 0.7^10)
1b 50,000x0.7^t
Approximately how many boxes that are 2 ft. by 2 ft. by 3.5 ft. fit inside of the back of a tractor trailer box truck whose dimensions are 28 ft. by 8 ft. by 9 ft.?
Solution:
Volume of trailer box= Number of boxes * Volume of Box
Volume of Trailer Box=Length*Width*Height
Dimensions of Trailer Box are 28 ft. by 8 ft. by 9 ft.
Volume of Trailer Box=28*8*9ft³=2016ft³
Dimensions of box are 2 ft. by 2 ft. by 3.5 ft.
Volume of Box=2*2*3.5ft³=14ft³
Volume of Trailer Box=Number of Boxes *Volume of Box
2016=Number of Boxes*14
To get, Number of Boxes, Let us divide by 14
2016/14=Number of Boxes=144
Number of Boxes=144
Answer: Option C:144 boxes
