The points on the number line do represent additive inverses. 3 and −3 are a zero pair, and when added they equal zero. The two numbers are the same distance from zero but in opposite directions.
Answer:
true
Step-by-step explanation:
because the question is he points on the number line do represent additive inverses. 3 and −3 are a zero pair, and when added they equal zero. The two numbers are the same distance from zero but in opposite directions. then it would equal 0
Answer:
Its because one is a positive integer and the other is a negative. So basically it is 3-3=0

Melinda worked 6.5 hours at her job. She makes $9.50 per hour. How much money did she earn for the day ?
Answer:
$61.75
Step-by-step explanation:
Hello,
If Melinda earns $9.50 per hour and she worked 6.5 hours, then her earnings for that day was $61.75.
This is simply the product of $9.50 * 6.5 = $61.75.
This assumption of earnings doesn't include tax reductions, unless her hourly pay includes those.
Cheers.
The ratio of the number of boys to the number of girls on the swim team is 4:2. If there are 24 athletes on the swim team, how many boys than girls are there?
Answer:
We have 8 more boys than girls on the swim team.
Step-by-step explanation:
The ratio of boys to girls on a swim team is represented as:
4 : 2
Total number of athletes is given as 24
Total ratio is given as:
4 + 2 = 6
Step 1
We find the number of boys and girls
Number of boys = 4/6 × 24 = 16 boys.
Number of girls = 2/6 × 24 = 8 girls.
Therefore, since we have 16 boys and 8 girls on the swim team, we have 8 more boys than girls on the swim team.
Compare and contrast natural numbers and rational numbers.
Natural numbers are strictly only plain numbers like no percents or integers, such as 1, 2, 3, 4, 5, 6 etc. Natural numbers are whole numbers and positive, so 0 would not be considered natural since it is not positive or negative
Rational numbers are numbers like 1, -100, .33, -10000, 2.4, etc it can be ALMOST anything, rational numbers fit every category but one IRRATIONAL
Irrational numbers are numbers like pie (3.145.......) it goes on forever and ever if the number never stops and repeats its called a repeating decimal, (HUGE TIP, IF YOU CAN MAKE IT A FRACTION IS IS ALMOST ALWAYS RATIONAL)
A computer downloads 30 megabits per second for "t" seconds. Write an
equation to represent the number of megabits, m, downloaded.
Answer:
M = 30t
Step-by-step explanation:
Given that a computer downloads 30 megabits per second for "t" seconds. That is, the rate at which the computer downloaded it is 30 megabits/second
Where time = t seconds
To Write anequation to represent the number of megabits, m, downloaded,
Rate = megabits/ time
Where
Rate = 30
Megabits = m
Time = t
Therefore, substitute all into the formula
30 = m/t
Make m the subject of formula
M = 30t
The equation is m = 30t

e. Is the a discrete random variable, a continuous random variable, or not a random variable? height of a randomly selected giraffe A. It is a discrete random variable. B. It is a continuous random variable. C. It is not a random variable.
Answer:
The correct answer is:
It is a continuous random variable (B)
Step-by-step explanation:
Continuous Random Variables are variables that take on a number of possibilities of values that cannot be counted. The values have infinite possibilities. In this example, the height of a Giraffe measured in meters can be an unlimited possibility if values say, 10.5m, 15.22m 12.0m etc. The possibilities are endless.
Discrete Random variables are variables that take on a number of possibility of occurrences that can be counted. For instance, if a dice is rolled, the possibilities can either be a 1, 2, 3, 4, 5 or 6. There are six values that can be gotten, nothing in-between.
I think the answer is B.

A homeowner's backyard is a rectangle with width 18 yards long and length 16 yards long. They plan to put in a square pool with side length 5 yards long in the backyard and then want to put tile in the rest of the entire backyard. How much tile do they need to buy?
Answer:
Step-by-step explanation:
Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;
Area of rectangle = Length * Width
Area of the rectangular backyard = 18yards * 16yards
Area of the rectangular backyard = 288yards²
If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²
The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool
The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²
Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use. The area needed for the tiles for the rest of the backyard is therefore 263yd².
Amount of tiles needed to buy can be expressed as 263/dimension of a tile.
Linda Gramham's Cinnamon Sugar Graham Cupcake recipe for 36 cupcakes requires 1 1/4 cups of sugar. How much sugar is required for 900 cupcakes? Reduce to lowest terms.
Answer:
31.25 or 31 1/4 cups
Step-by-step explanation:
1 1/4 = 36
x = 900
=> 5/4 = 36
x = 900
Cross multiply
=> 5/4 * 900 = 36 * x
=> 4500/4 = 36x
=> 1125 = 36x
=> 1125 / 36 = 36x / 36
=> 31.25 = x
31.25 = 31 1/4
So, 31.25 or 31 1/4 cups are required for 900 cupcakes.
[tex]\frac{125}{4}=31\frac{1}{4}[/tex] cups of sugar is required for 900 cupcakes.
First, it is convenient to convert the mixed fraction corresponding to the time to improper. To do this, the integer is multiplied by the denominator, to which the numerator is added. Divide this result by the denominator. The denominator of the improper fraction will be the same as the mixed number had. In summary:
[tex]a\frac{b}{c}=\frac{c*a+b}{c}[/tex]
In this case:
[tex]1\frac{1}{4}=\frac{4*1+1}{4}[/tex]
Solving:
[tex]1\frac{1}{4}=\frac{4+1}{4}[/tex]
[tex]1\frac{1}{4}=\frac{5}{4}[/tex]
On the other side, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, where a, b and c are known and x is the value to be calculated:
a ⇒ b
c ⇒ x
So:
[tex]x=\frac{cxb}{a}[/tex]
In this case, the rule of three can be applied as follows: Linda Gramham's Cinnamon Sugar Graham Cupcake recipe for 36 cupcakes requires [tex]1\frac{1}{4}=\frac{5}{4}[/tex] cups of sugar. If 900 cupcakes are made, how much sugar is required?
36 cupcakes ⇒ [tex]\frac{5}{4}[/tex] cups of sugar
900 cupcakes ⇒ x
Then:
x= (900 cupcakes× [tex]\frac{5}{4}[/tex] cups of sugar)÷ 36 cupcakes
Solving:
x= [tex]\frac{125}{4}[/tex] cups of sugar
In summary,[tex]\frac{125}{4}=31\frac{1}{4}[/tex] cups of sugar is required for 900 cupcakes.

Jesse estimates that it will cost $300,000 to send his newborn son to a private college in 18 years. He currently has $65,000 to deposit in an account. What simple interest rate would he need so that $65,000 grows into $300,000 in 18 years
Answer:
Simple interest rate (R) = 20% (Approx)
Step-by-step explanation:
Given:
Final amount (A) = $300,000
Number of year (T) = 18
Amount deposit (P) = $65,000
Find:
Simple interest rate
Computation:
interest = Final amount (A) - Amount deposit (P)
interest = $300,000 - $65,000
interest = $235,000
interest = [PRT] / 100
235000 = [(65,000)(R)(18)] / 100
Simple interest rate (R) = 20.085
Simple interest rate (R) = 20% (Approx)

Two kids at a summer camp, Tina and Winston, are competing in a potato sack race. Tina is younger, so she is given a head start of 33 meters. When the race starts, Tina hops at a rate of 1 meter per second, and Winston hops 4 meters per second. Eventually, Winston will overtake Tina. How long will that take? How far will Winston have to hop? It will take ___ seconds for Winston to hop ___ meters and catch up to Tina.
Answer:
It will take Winston 11 seconds to hop 44 meters and catch up to Tina
Step-by-step explanation:
Set up an equation where x represents the number of seconds:
Tina will be represented by s + 33 since she goes 1 m/sec and she has a 33 meter head start, and Winston will be 4s. We need to find when Winston will catch up, so we need an equal sign.
s + 33 = 4s
Solve for s:
s + 33 = 4s
33 = 3s
11 = s
= 11 seconds
Then, plug in 11 as s to find how many meters he will go:
s + 33
11 + 33 = 44
= 44 meters

Answer:
see below (I hope this helps!)
Step-by-step explanation:
p² = 4x² * (q(1 + r² / y²) / S)
p²S = 4x² * q(1 + r² / y²)
p²S / 4x²q = 1 + (r² / y²)
p²S / 4x²q - 1 = r² / y²
y² = r² / (p²S / 4x²q - 1)
y = √( r² / (p²S / 4x²q - 1) = √(r²4x²q / (p²S - 4x²q))
What is the missing exponent?
Answer:
0
Step-by-step explanation:
( 2x^2 y^m) ^6 = 64 x^12
We are interested in the y variable
The y on the right is not there so we can write it as y^0
y^m^6 = y^0
We know that a^b^c = a^(b*c)
y^(m*6) = y^0
The bases are the same so the exponents have to be the same
6m =0
m=0
The missing exponent is 0

Water flows through a pipe at a rate of 9 quarts every 3.5 years. Express this rate of
flow in cups per day. Round your answer to the nearest hundredth.
Answer:
0.01 rate per dayStep-by-step explanation:
Given that the water flow through a pipe occrs a a rate of 9quarts every 3.5 years, he rate of flow in cups per year will be expresssed as;
9quartz = 3.5years
x quartz = 1 year
cross multiply
9quarts * 1 = 3.5 years * x
9 = 3.5x
x = 9/3.5
x = 2.57142 years
Hence the rate flow of cup per year will be 2.57 years. But since the question asked us to look for the rate of flow per day, we will divivde 2.57 by 365days.
The rate of flow in cups per day = 2.57/365 = 0.00704rate per day
≈ 0.01 rate per day to the nearest hundredth
