Jason is saving up for a skateboard and helmet. The skateboard is $45.50 with tax and the helmet is $18.25 with tax. He earned 1/3 of the money by mowing lawns and the rest by babysitting. How much did Jason earn babysitting?
Let X be the amount he earned babysitting
Skateboard and helmet cost 18.25+45.50=$<<18.25+45.5=63.75>>63.75
He earned 63.75/3=$<<63.75/3=21.25>>21.25 mowing lawns
He earned 63.75-21.25=$<<63.75-21.25=42.5>>42.5 babysitting. Answer: \boxed{42.5}.
Jerri was using a recipe for a large cake that required one-third of a tablespoon of cinnamon. Instead of making one large cake, Jerri decided to use the recipe to make four small cakes. How much cinnamon should she use for each of the four small cakes?
To find out how much cinnamon Jerri should use for each of the small cakes, we need to divide the amount of cinnamon required for the large cake by the number of small cakes.
The amount of cinnamon required for the large cake is one-third of a tablespoon.
So, to find out how much cinnamon should be used for each small cake, we need to divide one-third tablespoon of cinnamon by four.
One-third tablespoon divided by four is equal to (1/3)/4 = 1/12 tablespoon.
So, Jerri should use 1/12 tablespoon of cinnamon for each of the four small cakes.
Molly's family has $3,000 set aside for an upcoming vacation. The family plans to spend 3/5 of this amount on gasoline for the drive and motel rooms along the way and 1/2 of the remainder on meals. How much does Molly's family plan to spend on meals?
To find out how much Molly's family plans to spend on meals, we need to follow these steps:
1. Find out how much money will be spent on gas and motel rooms. Multiply the total amount of money ($3,000) by 3/5:
$3,000 * 3/5 = $1,800
So, $1,800 will be spent on gas and motel rooms.
2. Find out the remainder after spending on gas and motel rooms. Subtract the amount spent on gas and motel rooms ($1,800) from the total amount ($3,000):
$3,000 - $1,800 = $1,200
So, $1,200 is the remaining amount.
3. Find out how much money will be spent on meals. Multiply the remaining amount ($1,200) by 1/2:
$1,200 * 1/2 = $600
So, Molly's family plans to spend $600 on meals.
Rational numbers m and n are plotted on the number line below.
The number line showing numbers from -4 to 4 each divided into 4 segments has point n halfway between 0 and the first segment to the left of 0 and point m halfway between third and the fourth segment to the right of 0.
Based on the number line, which statement is true?
Based on the given description, point n is halfway between 0 and the first segment to the left of 0, which means it is located at -1.5.
Next, point m is halfway between the third and the fourth segment to the right of 0. Therefore, m is located at 3.5.
So, the statement that is true based on the number line description is that n is less than m.
Rational numbers m and n are plotted on the number line below.
The number line showing numbers from -4 to 4 each divided into 4 segments has point n halfway between 0 and the first segment to the left of 0 and point m halfway between third and the fourth segment to the right of 0.
Based on the number line, which statement is true?
A. n - m is positive
B. n + m is positive
C. n + m is negative
D. -(n - m) is negative
Based on the number line described, point n is located at -1.5 and point m is located at 3.5.
To determine which statement is true, we can start by calculating n - m:
n - m = -1.5 - 3.5 = -5
Since n - m is negative, statement A, which says n - m is positive, is not true.
Next, we can calculate n + m:
n + m = -1.5 + 3.5 = 2
Since n + m is positive, statement B, which says n + m is positive, is true.
Statement C, which says n + m is negative, is not true.
Finally, we can calculate -(n - m):
-(n - m) = -(-5) = 5
Since -(n - m) is positive, statement D, which says -(n - m) is negative, is not true.
Therefore, the correct answer is B. n + m is positive.
