x/235 = 60/100 SHOW ALL WORK FOR WHAT DOES X equals THIS IS DUE IN 3mins WILL GIVE BRAINLY

Answers

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

The plane continued to descend, but leveled off to an angle of descent of 3° degrees for approximately 2 miles. How many feet did they drop in altitude (d)? Round to the nearest 10th.

Answers

ANSWER: Plane dropped 6097 feet in altitude.
BECAUSE: An airplane is at point A from where it continued to descend by 30° for an approximate distance of 2 miles
∠ACB = Angle of descent = 30°
Distance BC = 2 miles
Let the plane dropped the altitude = h miles
Now tan 30° =


h = 1.155 miles
h ≈ 1.16 miles
Since 1 mile = 5280 feet
1.15 miles = 5280×1.16 feet
= 6097 feet
Therefore, the plane dropped by 6097 feet vertically.

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?

Answers

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

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​

Answers

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
