Answer:
Step-by-step explanation:
divide the money or degrees by the hours or form of time they give. for the first one you divide 585/52 to get $11.25 an hour.
Answer:
1) .
2)
hence, answer is 7/12.
3) We have to divide £72 in the ratio 2:3:1
the total of the ratio is=2+3+1=6
so on dividing 72 into 6 parts we have 72/6=12
First '2' parts=2×12=24
second '3' part=3×12=36
last '1' part=1×12=12
so dividing £72 in the ratio 2:3:1 is: £24,£36 and £12
4) 39 people out of 65 have blonde hair.
Number of people who do not have blonde hair=65-39=26
percentage people who do not have blonde hair is given by:
Hence, percentage people who do not have blonde hair is 40%
5) 20% of 90= (20/100)×90
=18
Hence, 20% of 90 is 18.
6) Factorise
7) Expand
8)
.
9)
10)
11) x= -4 y=3
and z=4 x-y^3
z=4×(-4)-3^3
z= -43
12)
13)
Hence x= -2
14) 5,10,15,20,....
Hence, nth term is 5n.
15) (63×128)/32.9=245.106.
16) 938×21=19698.
Answer:
9/20
Step-by-step explanation:
simply divide 9 by 20 and thats the answer in a fraction then compare the fractions to each other
Answer:
Each banana costs $0.33.
Step-by-step explanation:
This can be solved as a rule of three problem.
Rule of three problem:
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.
In this problem, the measures are:
- The number of bananas bought
- The total cost
As the number of bananas bought increases, the total cost will increase too, which means that our rule of three is direct.
3 banatas costs $1. We want to know how much costs each banana, so:
3 bananas - $1
1 banana - $x
3x = 1
x = 0.33
Each banana costs $0.33.
