Answer: 38 students
Step-by-step explanation:
There are only 90 students. You subtract 90 minus the 32 that said social studies was there favorite. So now you have 58 then minus the people who said both which was 20. Your left with 38. So 38 students said just math as there favorite subject.
B) square root 62 inches
C) square root 128 inches
Answer:
a). The total number of cattle shared among the three children=200
b). Anita's share=120 cattle
Lordia's share=32 cattle
Richmond's share=48 cattle
Step-by-step explanation:
a)
Step 1
Determine fraction shared between Lordia and Richmond as follows;
Lordia:Richmond=2:3
Let the total cattle be x
Lordia's fraction=2/(2+3)=2/5 of x=(2/5)x
Lordia's fraction=(2/5)x
Richmond's fraction=3/(2+3)=3/5 of x=(3/5) x
but;
x=80 cattle
replacing;
Total number of cattle Lordia got=(2/5)×80=32 cattle
Total number of cattle Richmond got=(3/5)×80=48 cattle
Step 2
Express the total cattle Mr. Atinga had initially as follows;
Let the initial number of cattle be y
The fraction remainder given to Lordia and Richmond=Initial number-fraction of the totat given to Anita
where;
Initial number=y
fraction of the total given to Anita=3/5 y
replacing;
The fraction remainder given to Lordia and Richmond=y-3/5 y=2/5 y
but;
2/5 y=80
y=80×5/2=
y=200
The total number of cattle shared among the three children=200
b).
Anita's share=(3/5)×200=120 cattle
Lordia's share=(2/5)×80=32 cattle
Richmond's share=(3/5)×80=48 cattle
Answer: $7.50
Step-by-step explanation:
Their ages are jan's age = 19 and tritts age be 11 yaers
Algebra is a branch of mathematics that deals with symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables. In our real-life problems, we often see certain values that keep on changing. But there is a constant need to represent these changing values.
Given:
Jan's Age is 3 years less than twice Tritts age.
sum of their ages is 30.
let tritts age be x
jan age= 2x -3
Now, sum of their ages = 30
x+ 2x-3 = 30
3x= 33
x=11
hence, jan's age = 19 and tritts age be 11 yaers

Answer:
$0.80
Step-by-step explanation:
To find the sales tax you:
Divide 4% by 100 ( because a percentage is always out of 100) {= 0.04}
Multiply 0.04 by 20 ( the answer becomes $0.80)
When doing this you primarily finding 4% of $20.
