A large square is divided into 4 smaller squares; then small left square is
divided into 4 smaller squares as well. What fraction of the large square is
shaded?
OPTIONS
4 over 5
3 over 8
4 over 9
1 over 3
1 over 2
Answer:
The total fraction shaded is 1/2
Step-by-step explanation:
Here, we want to know the fraction shaded
As we can see, the box is originally divided into 4
So each of the 4 parts are 1/4
for the first part, we have 4 divisions;
This means each of the divisions with respect to the whole fraction will be 1/4/4 = 1/16
Now, two of these are shaded, making 1/16 and 1/16
Secondly, we have half of the 1/4 : So with respect to the whole, we have 1/4/2 = 1/8
for the third part, the whole 1/4 is shaded
and lastly, we have an unshaded 1/4
so, the total fraction shaded will be ;
1/16 + 1/16 + 1/4 + 1/8
= (1 + 1 + 4 + 2)/16 = 8/16 = 1/2

x/235 = 60/100 SHOW ALL WORK FOR WHAT DOES X equals THIS IS DUE IN 3mins WILL GIVE BRAINLY
Answer:
x = 141
Step-by-step explanation:
x/235 = 60/100
100x = (235)(60)
100x = 14,100
divide both sides of the equation by 100:
x = 141
Answer:
141
Step-by-step explanation:
reduce the fraction 60/100 which will turn into x/235=3/5, simplify and it will go to 5x=705, divide both sides and it will equal 141

Suzy makes 20 dollars an hour at her job. Bill only makes 10 dollars an hour but he has a starting bonus of 20. When will Suzy and Bill make the same amount of money for the same number of hours worked? How much will they both earn at the same time?
Answer:
2 hours
Suzy would earn $40
Bill will earn $40
they will both earn $80
Step-by-step explanation:
The total amount suzy earns is a function of the total hours worked. Let t represent time
total income of suzy = $20t eqn 1
Bill's income = starting bonus + variable pay
= $20 + $10t
We are looking for when they would earn the same amount :
20t = $20 + $10t eqn 2
collect like terms and solve for t
10t = $20
t = 2 hours
Substitute for t in either eqn 1 or 2
20(2) = $40
Suzy would earn $40
Bill will earn $40
they will both earn $80
