Answer:
It would be 70
Step-by-step explanation:
First step: Divide 156 by 2
156 / 2 = 78
Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).
78 - 8 = 70 Desktops
78 + 8 = 86 Laptops
Hope this helps :)
A bicycle wheel has outer diameter 32cm. How far will the cyclist travel if the wheel rotates 100π times? Give your answer in kilometres and correct to two decimal places.
Answer:
[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]
Step-by-step explanation:
Diameter [tex]d=32cm=0.32m[/tex]
Number of rotations [tex]N=100\pi[/tex]
Generally the circumference of the wheel is mathematically given as
[tex]C=2\pi r[/tex]
[tex]C=2\pi (0.32)^2/4[/tex]
[tex]C=1.005309649m[/tex]
[tex]C=1.0m[/tex]
Generally the total distance traveled T is mathematically given as
[tex]T=N*C[/tex]
[tex]T=100\pi *1m[/tex]
[tex]T=314.1592654m \approx 314.16m[/tex]
Total distance traveled T in Kilometres
[tex]T=314.1592654m[/tex]
[tex]T=\frac{314.1592654m}{1000}[/tex]
[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

A company makes cylindrical crackers that have a cylindrical hole in the middle.
The diameter of the entire cracker is 16 mm the diameter of the hole is 8 mm, and the cracker is 18 mm long.
What is the volume of the material used in each cracker?
Round to the nearest cubic millimeter.
Answer:
2714 mm3
Step-by-step explanation:
Volume of the material used in each cylindrical cracker is 2714 cubic mm.
Volume of a cylinder: Volume of a cylinder is given by the expression,
Volume = πr²h
Given in the question,
Cylindrical cracker have a cylindrical hole in middle. Diameter of entire cracker = 16 mm Diameter of the cylindrical hole = 8 mm Length of the cracker = 18 mmMaterial used in cracker = Volume of the whole cracker - Volume of the cylindrical hole
= [tex]\pi (\frac{16}{2} )^2(18)-\pi (\frac{8}{2} )^2(18)[/tex]
= 1152π - 288π
= 864π
= 2714.34
≈ 2714 cubic mm.
Therefore, volume of the material used in each cracker will be 2714 mm³.

The entry ticket to a local football game costs $10 for an adult and $5 for a child. A group of 100 people paid an entry fee of $710. How many adults and how many children were there in this group?
Answer: Adults = 58
Children = 42
Step-by-step explanation:
Let adults be denoted as a
Let Children be denoted as c
a + c = 100 ...... i
10a + 5c = 710 ...... ii
Multiply I by 5
Multiply ii by 1
5a + 5c = 500 ...... iii
10a + 5c = 710 ...... iv
Subtract iii from iv
5a = 210
a = 210/5
a = 42
Since a + c = 100
c = 100 - 42 = 58.
Adults = 58
Children = 42
A triangle has sides with the measures of 11m, 11m, and 25m. State if this is a triangle or not.
yes or no
Answer:
no
Step-by-step explanation:

The sum of 11 and 11 is less than 25 and therefore, this triangle is not possible.
80% of what number is 190
Answer: I would have to say 237.5
(152 is 80% of 190)
Step-by-step explanation:
If 190 is 80% of a number then you need to reverse the process, .8 * 190 = 80% OF 190 but 190 / .8 = 237.5 which means that 190 is 80% of 237.5
