If it's an equilateral triangle than all the sides are the same. So 20 would be the base. Multiply 20 by 3, which is 60.
Answer:
¹/₄x - 3 ≥ 2
+ 3 + 3
4(¹/₄x) ≥ 4(5)
x ≥ 20
Step-by-step explanation:
Answer: Van = 198 students
bus = 672 students
Step-by-step explanation:
Let x represent the number of students in the vans and y represent the number of students in the buses, then from the first statement , we have
11x + 4y = 289 ................. equation 1
From the second statement, we also have
7x + 12y = 581 ............... equation 2
Combining the two equations together and solving simultaneously , we have
x = 11 and y = 42
therefore the number of students vans can carry will be'
11x + 7x
= 11(11) + 7 (11)
= 121 + 77
= 198
The number of students buses will carry will be
4y + 12y
= 4(42) + 12(42)
= 168 + 504
= 672
Answer:
Sample mean for solution 1: 19.27; sample mean for solution 2: 10.32
Step-by-step explanation:
To find the sample mean, find the sum of the data values and divide by the sample size.
For solution 1, the sum is given by:
9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7
The sample size is 10; this gives us
192.7/10 = 19.27
For solution 2, the sum is given by:
10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2
The sample size is 10, this gives us
103.2/10 = 10.32
This question is based on multiplication.
Given situation is -
by recycling 1 ton of paper , the amount of water saved is = 6953 gallons
So, by recycling 4 tons of paper , the amount of water saved will be=
= gallons
Hence, 27812 gallons of water are saved by recycling 4 tons of paper.
