Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
Answer: (a) 11.8
(b) 13
Step-by-step explanation:
Since George wants to put a string of lights around , it means we will have to consider the perimeter of the shape.
Perimeter of a rectangle is given by :
P = 2( L+B)
P = 2 ( 2.5 + 3.4)
P = 2 ( 5.9)
P = 11.8 meters
(b) Since he wants to put an addition to his wooden deck that is 0.6 meters longer , then the perimeter will be the perimeter of the first shape + 2(0.6). We used 2(0.6) because the two lengths of the rectangle must be considered
Therefore, we have
P = 11.8 meters + 2(0.6)
= 11. 8 + 1.2
= 13 meters
Therefore George needs 13 meters length of light
Answer:
Without the answers provided with the question, it would take the bus 3.85 (rounded to nearest hundredth) hours to get 30 km away from Orlando.
Step-by-step explanation:
It takes the bus approximately (when rounded to the nearest tenth) 4.3 hours to get to Orlando from Michigan hence the bus drives 70 km/h and the distance is 300 km.
You can find this by dividing 300 by 70, which equals 4.28571428571
Answer:
Step-by-step explanation:
Given:
Number of people to be seated should be greater than 75.
Let be the number of people. So,
Now, there is a single private chef's table that can seat 3 people.
Tables bought by the owner =
Number of people seated in 1 table = 4
So, number of persons that can be seated in tables =
Now, total number of persons that can be seated in these two types of tables is the sum of 3 and
Therefore,
But,
Hence, the inequality to show the situation is:
