How many flags are needed? First fill in the blanks on the left side of the equation using three of the ratios shown. Then write your answer on the right side of the equation.
Answers
Complete question :
A runner's racecourse has a total distance of 2.5 mi. Race officials want to mark the course every 200 yd with a flag, including one at the finish line. (The starting line does not need a flag. How many flags are needed?
Answer:
22 flags
Step-by-step explanation:
Given that total distance = 2.5 miles
Marked distance = every 200 yards
Ratio of yard to miles:
1 mile = 1760 yards
Total distance in yards :
Note :
1 mile = 5280 feet
1 yard = 3 feet
Given that:
1 flag per 200 yards
Number of flags :
2.5 miles * (5280 / 1 ) * (1 /3) * (1 / 200) = 22 flags
Similarly ;
Since 1 mile = 1760 yards
Total distance in yards : (2.5 * 1760) = 4400 yards
Number of flags :
Total distance in yards / marked distance
= 4400 / 200
= 22 flags
Big Time Movers charges an initial fee of $24.50, plus $12.75 an hour for their moving services. On holidays, they charge 2.5 times their regular total amount. If they made $188.75 on a job on New Year’s Day, how many hours did they work?
This equation represents the data:
2.5(12.75x + 24.50) = 188.75
Big Time Movers worked ________ hours on New Year’s Day.
Answers
Big time movers worked 4 hours on New Year’s Day.
Show your work:
2.5 (12.75x +24.50) = 188.75
31.875x + 61.25 = 188.75
31.875x = 188.75 - 61.25
31.875x = 127.50
X = 127.50 / 31.875

Now it is given that,
Weight of onions = 102 bushels
Weight of peaches = 101 bushels
Weight of corn = 103 bushels
Total weight of crops = Weight of onions + Weight of peaches + Weight of corn
⇒ Total weight of crops = 102 bushels + 101 bushels + 103 bushels
⇒ Total weight of crops = 304 bushels
Thus, he total weight of the crops is 304 bushels.

The growth rate of the California fan palm is what inches per year and the queen palm's growth rate is what inches per year. So, the what grew faster.
Answers
Answer:
Queen palm tree grew faster than the California fan palm tree
Step-by-step explanation:
One California fan palm tree grows 51 inches in 3 years
Rate = 51/3 = 17 inches/year
A queen palm tree grows 48 inches in 4 years
Rate = 48/4 = 12inches/year
Clearly the Queen palm tree grew faster than the California fan palm tree as Queen palm tree grows 12inches/year than California Fan palm tree 17 inches/year .
Answer:
the california fan palm
Step-by-step explanation:
you have to know which tree grew faster so you have to know how many inches they grow per year so you have to...
divide 51 by 3 and the answer is 17 inches per year
and divide 48 by 4 and the answer is 12 inches per year
so 17 is greater than 12

A cook has a scoop that measures ¼ cup. A bread recipe calls for 1 ¼ cups of sugar and 2 ½ cups of flour. The cook uses the scoop to measure and put both ingredients into a bowl. How many total scoops of both ingredients does the cook put into the bowl?
Answers
Given:
A cook has a scoop that measures [tex]dfrac{1}{4}[/tex] cup.
Required sugar for bread recipe = [tex]1\dfrac{1}{4}[/tex] cups
Required flour for bread recipe = [tex]2\dfrac{1}{2}[/tex] cups
To find:
The total number of scoops of both ingredients does the cook put into the bowl.
Solution:
Required amount of sugar and flour for the bread recipe is
[tex]=1\dfrac{1}{4}+2\dfrac{1}{2}[/tex]
[tex]=\dfrac{1\times 4+1}{4}+\dfrac{2\times 2+1}{2}[/tex]
[tex]=\dfrac{4+1}{4}+\dfrac{4+1}{2}[/tex]
[tex]=\dfrac{5}{4}+\dfrac{5}{2}[/tex]
Taking LCM, we get
[tex]=\dfrac{5+10}{4}[/tex]
[tex]=\dfrac{15}{4}[/tex]
Now,
[tex]\text{Number of scoops}=\dfrac{\text{Total amount of sugar and flour}}{\dfrac{1}{4}}[/tex]
[tex]\text{Number of scoops}=\dfrac{\dfrac{15}{4}}{\dfrac{1}{4}}[/tex]
[tex]\text{Number of scoops}=\dfrac{15}{4}\times \dfrac{4}{1}[/tex]
[tex]\text{Number of scoops}=15[/tex]
Therefore, the required number of scoops is 15.
