First we have to convert 1 mile into feet, then divide by two to find how many feet she walked in a half an hour.
There are 5280 feet in a mile.
5280/2640
The correct answer is 2640.
Hope this helped! Please comment or DM me if you have any questions or still need help. :)
This is how I learned.
Place a point above the line segment. Open the compass so that you can create arcs on the line segment. One arc should intersect on the right side, the other on the left. Name these points (A and B, for example). Move the compass to one point. Use the same radius in the compass<em /><em /> and make an arc below the line segment. Then move the compass to the opposite point and make another arc (with the same radius). The two arcs should intersect. Draw a line from the point above the line segment to the new intersection and you have your perpendicular bisector.
Answer:
I'm pretty sure it's 108.
Step-by-step explanation:
12 x 12 x 12 = 1,728
4 x 4 = 16
1,728 ÷ 16 = 108
Answer:
45%
Step-by-step explanation:
First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.
For a percentage, we need a fraction out of 100. To do this, we can multiply the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.
A percentage is just the numerator of a number over 100 therefore it is equal to...
45%
Answer:
52
Step-by-step explanation:
given that the number is a
The expression for Ten less than 5 times the value of a number is given by
5a - 10
10 times the quantity of 12 more than one-fourth of the number.
a/4 is one-fourth of number
12 more than one-fourth of the number
a/4 + 12
expression for 10 times the quantity of 12 more than one-fourth of the number. is given by
10(a/4 + 12) = 10a/4 + 12*10 = 2.5a + 120
Given that the above two expression are equal
equating them we have
5a - 10 = 2.5a + 120
adding 10 both sides
=>5a - 10+ 10 = 2.5a + 120 + 10
=> 5a = 2.5a + 130
subtracting 2.5a from both sides
=> 5a - 2.5a = 2.5a + 130 - 2.5a
=> 2.5a = 130
dividing both side by 2.5
=> a = 130/2.5 = 52
Thus, value of a is 52
