Mercury Orbits the sun in 87 24/25 earth days. Venus Orbits the sun in 224 7/10 Earth days, and Mars Orbits the sun in 686 49/50 days. Write each mixed number as a decimal.

Answers

Mercury: 87 24/25
Venus 224 7/10
Mars 686 49/50

All we need to do is to convert fractions so they have a denominator of 10, 100, 1000 etc.

87 24/25 = 87 96/100
224 7/10 stays the same
686 49/50 = 686 98/100

Now we can easily convert them into decimals:

Mercury: 87.96
Venus: 224.7
Mars: 686.98

The correct answers are:

87.96; 224.7; 686.98.

Explanation:

In order to write these numbers as decimals, we need to convert the fractions to fractions with denominators of 10, 100, or 1000.

224 7/10 already has a denominator of 10; this makes it 224.7.

For 87 24/25, we can multiply the denominator by 4 to make 100. Doing that means we need to multiply the numerator by 4 as well:

87 (24*4)/(25*4) = 87 96/100 = 87.96

For 686 49/50, we can multiply the denominator by 2 to make 100. Doing that means we need to multiply the numerator by 2 as well:

686 (49*2)/(50*2) = 686 98/100 = 686.98

If 2 pounds of strawberries cost $4.50, how much would 3 pounds cost?

Answers

3 pounds cost $6.75

to help you, turn it into a fraction, 2 punds ove 2.50 equals 3 pounds over X

Answer this question correctly and you'll get a good 13 points! Please help me! :) Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the distance in 4.5 h. Car B traveled 5 mph slower than Car A.How fast did Car B travel? How many MPH?

Answers

Time = Distance / Speed OR Distance = Time * Speed OR Speed = Time * Distance

Since both cars travelled the same distance; it is safe to have this formula to get the actual distance travelled.

Let X = distance in MPH

Car A = Car B
4 hours * X    = 4.5 hrs * (X - 5MPH)
4X    = 4.5(X-5)
4X = 4.5X - 22.50
4X - 4.5X = -22.50
-0.5X = -22.50
X = -22.50 / -0.5
X = 45 MPH

Speed of Car B = 4.5 hrs * (45-5)
   = 202.50 - 22.50
Speed of Car B = 180 MPH

TO CHECK
Speed of Car A = 4hrs * 45 MPH
Speed of Car A = 180 MPH

5. L1. Tisha collects old books. She has
2 shelving units, and each shelving
unit has 3 shelves. Each shelf holds
12 books. If both shelving units are
filled with books, how many books
does Tisha have in all

Answers

Tisha have 72 books in all.

Step-by-step explanation:

Given,

Number of shelving units = 2

One shelving unit has 3 shelves.

2 shelving units will have = 3*2 = 6 shelves

Books hold by each shelf = 12 books

Books hold by 6 shelves = 12*6 = 72 books

As the shelves are filled with books, therefore,

Tisha have 72 books in all.

Answer:

Cone is equal to 3, white ice cream is equal to 2, and the pink is equal to 1.

Step-by-step explanation:

Something times something times something is equal to 27, and 27=3x is equal to 3. The cone is equal to 3.

3+3=6, and since 10-6 =4, 4=2x, so the white ice cream is equal to 2.

3+3+3=9, and 2+2=4, 9+4=13, so 15-13=2, and 2=2x, so the pink ice cream is equal to 1.
