Subtract using the number line.
−1/3 − (−1/2)
Answers
The answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that:
The fraction numbers are 1/3 and -1/2
As we know,
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
The number expression is:
−1/3 − (−1/2)
From the number line:
Drawing line segment length of 1/3 left side
Drawing line segment length of 1/2 left side
Taking difference using number line:
= 1/6
Also, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= −1/3 − (−1/2)
= -1/3 + 1/2
= (-2+3)/6
= 1/6
Thus, the answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).

Pauline spent $7.50 every day for 3 days. Which expression is the best choice to help her determine the total amount of money she spent?
(7.50)(−3) = −22.50; she spent $22.50
(−7.50)(3) = −22.50; she spent $22.50
(−7.50)(−3) = 22.50; she spent $22.50
(7.50)(3) = 22.50; she spent $22.50
Answers
Answer:
The correct option is 2.
Step-by-step explanation:
It is given that Pauline spent $7.50 every day for 3 days.
Amount spent on each day = $7.50
Number of days = 3
Spent amount and expenditure are always negative.
Total amount of money she spent is
[tex]Total =(-7.50)(3)[/tex]
On simplification we get
[tex]Total =-22.50[/tex]
She spent $22.50 and required expression is (−7.50)(3) = −22.50. Therefore the correct option is 2.

Answer:
Angles that are congruent are complementary to the same angle
Step-by-step explanation:
see that attached figure to better understand the problem
we know that
Two angles are complementary if their sum is equal to [tex]90\°[/tex]
[tex]m<KJM=m<KLM=90\°[/tex]
[tex]m<KJC=m<MLC[/tex] -----> equation A
[tex]m<KJM=m<KJC+m<CJM[/tex]
so
[tex]m<KJC+m<CJM=90\°[/tex] -----> equation B
[tex]m<KLM=m<KLC+m<MLC[/tex]
so
[tex]m<KLC+m<MLC=90\°[/tex] -----> equation C
Substitute equation A in equation C
So
[tex]m<KLC+[m<KJC]=90\°[/tex]
That means------> angles ∠KLC and ∠KJC------> are complementary angles
therefore
Angles that are congruent are complementary to the same angle

the second of three numbers is 1 less than the first. The third number is 5 less than twice the second. If the number exceeds the first number by 12, find the three numbers
Answers
The three numbers are found by forming and solving a system of equations: the first number is 19, the second is 18 (which is one less than the first), and the third is 31 (which is 5 less than twice the second and exceeds the first by 12).
To solve the problem of finding the three numbers, we can set up a system of equations based on the information given:
The first number is x.The second number is one less than the first, so it is x - 1.The third number is 5 less than twice the second, which translates to 2(x - 1) - 5.The third number also exceeds the first by 12, so 2(x - 1) - 5 = x + 12.Now we can solve for x:
2(x - 1) - 5 = x + 122x - 2 - 5 = x + 122x - x = 12 + 2 + 5x = 19The first number is 19. The second number is 18 (19 - 1), and the third number is 31 (2(18) - 5).
Thus, the three numbers are 19, 18, and 31.
how much money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest?
Answers
Let me know if I wrong
The $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that:
simple interest account to earn $500 in interest in 5 years at 4% annual interest
As we know the simple interest formula is:
I = Prt
Here
I = $500
t = 5 years
r = 4% = 0.04
500 = P(0.04)(5)
P = 500/0.2
The money that must be deposited in a simple interest account to earn $500 is:
P = $2500
Thus, the $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.

The unit rate for $18 for 24 pounds
Answers
Final answer:
To find the unit rate of $18 for 24 pounds, you divide the total cost by the number of pounds, resulting in a unit rate of $0.75 per pound.
Explanation:
The student is asking how to calculate the unit rate of a product that costs $18 for 24 pounds. To find the unit rate, you divide the total cost by the total number of units (in this case, pounds). So, the calculation for the unit rate in this question would be:
$18 ÷ 24 pounds = $0.75 per pound
Thus, the unit rate is $0.75 per pound. This means for every pound of the product, you pay $0.75.

Answers
The submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
A Navy submarine descended from sea level at a rate of seven feet per second writing the descendent rate as an integer.
The rate of drop is 7 feet per second. 7 x 10(60), or 7 x 600, would be the subs elevation.
Consequently, the sub's elevation would be 4,200 feet below sea level.
Thus, the submarine's elevation after 10 minutes is 4200 feet if the Navy submarine descended from sea level at a rate of seven feet per second.

How many 1/4 ft pieces can you cut from a string that is 15 feet long
Answers
so the answer is 60 pieces
You can cut 60 pieces of 1/4 foot each from a string that is 15 feet long by carrying out the operation 15 ÷ 1/4, which turns into multiplication by the reciprocal of the fraction, 15 x 4 equals 60.
Explanation:The question is asking how many 1/4 ft pieces you can cut from a 15 feet long string. In other words, you want to divide the total length of the string by the length of each piece you're cutting out. So you will carry out a division operation: 15 ÷ 1/4. When dividing by a fraction, you actually multiply by its reciprocal. The reciprocal of 1/4 is 4, so 15 ÷ 1/4 becomes 15 × 4, which equals 60. Therefore, you can cut 60 pieces of 1/4 foot each from a string that's 15 feet long.
