Step-by-step explanation:
First we need to find out what they all 3 equal, with multiplication.
5×5=25
10×5=50
20×5=100
In each of these problems, the answer is multiplying itself by 2 in order to get to the next answer. So this is how they are related
Answer:
$4000 was invested at 4%, 2500 was invested at 3%
Step-by-step explanation:
First and foremost the question has to be define.
Total amount raised is $6500
Savings account percentage simple interest =3%
Government Bond: 4% simple interest
Equation for amount invested at each rate:
(6500-x)0.03 + 0.04x = 235
195 - 0.03x + 0.04x = 235
0.01x = 40
x = 4000
$4000 was invested at 4%, 2500 was invested at 3%
Answer:
20 dollars
Step-by-step explanation:
15 dollars times 12 people to see how much money she got/has right now is 180 dollars
then take 200-180 to get <u>20</u>
Answer:
25
Explanation:
By Using Pythagoras Theorem,
h^2=p^2+b^2
or, x^2=(24)^2+7^2
or, x^2=576+49
or, x^2=625
or, x=√625
•°• x=25

Answer:
Step-by-step explanation:
A) If the playing times are to be the same, then the two expressions for playing time will be equal to each other.
Ron = Sam
3 +1.25c = 8 +0.75c
0.50c +3 = 8 . . . . . . . . . . subtract 0.75c from both sides
0.50c = 5 . . . . . . . . . . . subtract 3 from both sides
c = 5/0.50 = 10 . . . . . divide by the coefficient of c
Each would have to complete 10 chores for their playing times to be the same.
__
B) When c = 4, we have ...
Ron: 3 +1.25·4 = 3 +5 = 8
Sam: 8 +0.75·4 = 8 +3 = 11
Sam spent the most gaming time if both completed 4 chores.
