Answer:
1127 miles
Step-by-step explanation:
Since on her last route, she earned $450.80. And she earned $0.4 for every mile.
The amount earned divided by the amount earned per mile would give us the value of distance covered.
Thus,
distance covered = [tex]\frac{450.80}{0.40}[/tex]
= 1127
Thus, the distance covered by Alexa on he last route is 1127 miles.
simplifu the ratio : 25 dollars to 10 cents
Answer:
150 cents: 1 cent
Step-by-step explanation:
We know every dollar has 60 cents so we can do
25*60=1500 cents

Daniel owes his sister $33. His sister said that she would give him a third off the debt. Write an expression that you could use to solve to find how much Daniel would owe his sister.
Answer:
P=33-11
Step-by-step explanation:
given that Daniel owes her $33
a third of $33
is 1/3*33
=$11
now let the amount Daniel will owe her after giving her a third of the debt be P
therefore the expression to find how much Daniel owes her will be
P=33-1/3*33
simplifying the expression we have
P=33-11
P=$22
Daniel will owe her $22

Maurice has a house washing service that power washes houses on the weekends. He washed 4 small houses in 4 hour and 40 minutes last saturday. What was his average washing time per house? (Express your answer in hour & minutes per house)
Answer: It should be one hour and 10 minutes for the average.
Step-by-step explanation: You would convert the 4 hours into minutes to get 240, then add the 40 to get 280. You would divide that by 4(for the number of houses) to get 70 minutes. Convert that into hours and minutes to get your answer.
At the Royal Dragon Chinese restaurant, a slip in the fortune cookies indicatos a dollar amount that will be subtracted from your total bill, A bag of 10 fortune cookies is given to you from which you will select one. If seven fortune cookies contain "$1 off," two contain "$2 off," and one contains "$6 off," determine the expectation of a selection.
Answer:
We can expect $1.7 off
Step-by-step explanation:
We are given 10 fortune cookies out of which
$1 off = 7 cookies
$2 off = 2 cookies
$6 off = 1 cookie
Probability
A = drawing $1 off cookies P(A) = 7/10
B= drawing $2 off cookies P(B) = 2/10
C= drawing $6 off cookie P(B) = 1/10
Expectation = 1*7/10 + 2*2/10+ 6*1/10
= 7/10 + 4/10 + 6/10
= 17/10 = $1.7 off

rebecca uses 3/4 gallon of paint to cover 1 wall. she has three gallons of paint. how many walls can she paint?
Answer:
4 walls
Step-by-step explanation:
First we could re-write 3 gallons with a denominator of 4 which would be 12/4 gallons. Next, we could divide like so:
12 divided by 3 = 4
Our answer is 4 walls
Hope this Helps!!! :)
She can paint 4 walls in 3 gallons of paint.
What is multiplication?Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.
Example - 2 × 3 means 2 is added three times or 3 is added 2 times.
Given, the Rebecca uses 3/4 gallon of paint to cover 1 wall.
And she has three gallons of paint.
Now to paint the wall;
number of wall that she can paint = number of gallon she has÷3/4
Number of wall that she can paint = 3 ÷ 3/4
Simplifying the above term to multiplication,
Number of wall that she can paint = 3 x 4/3
Number of wall that she can paint = 4
Therefore, she can paint 4 walls in 3 gallons of paint.

2x−1/15 = 7/3
Answer:
x=18/15, or 1[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Convert 7/3 into a fraction with denominator 15. Multiply both sides by 5 to get 35/15. Now, we add 1/15 to it to cancel out on both sides.
Our new equation is 2x=36/15
Divide by 2 on both sides

Graph the line with the equation y=1/4x-4
Answer:
Step-by-step explanation:
The required graph of the line y = 1/4x - 4 is attached below that represents a straight line that slants upward from left to right,
To graph the line with the equation y = 1/4x - 4, we can use the slope-intercept form of a linear equation.
In the given equation, y = 1/4x - 4, we can identify the slope and y-intercept:
Slope (m) = 1/4
Y-intercept (b) = -4
The graph of the line y = 1/4x - 4 will be a straight line that slants upward from left to right, with a slope of 1/4 and crossing the y-axis at -4.

10. Which of the following sets of numbers represents a Pythagorean
Triple?
A {10, 5, 12}
B {2,4,5)
C {1,2,3}
D {14, 48, 50 }
Answer:
D
Step-by-step explanation:
Trust me I used a calculator and and different one to make sure my answer was correct.
{14, 48, 50} represents a Pythagorean Triple, hence option (D) is correct.
If three sides of any triangle are a, b and c and c is the largest one then the condition that a, b and c will form a Pythagorean triplet is as:
c² = a² + b² -----(1)
An option which will satisfy the condition (1) will form a Pythagorean Triple.
Let's check for all the given options:
A) {10,5,12}
Since, 12 is the largest number out of three.
Therefore, c = 12, a = 5, b = 10
Now,
a² + b² = 5²+10²
a² + b² = 25+100
a² + b² = 125
a² + b²≠ 15²
a² + b²≠ c²
Hence, {10, 5, 12} will not form a Pythagorean Triple. Option (A) is incorrect.
B) {2,4,5)
c = 5, a = 2, b =4
a² + b² = 2²+4²
a² + b² = 4+16
a² + b² = 20
a² + b² ≠ 5²
Hence, option (B) is also incorrect.
(C) {1,2,3}
c = 3, a = 1, b = 2
a² + b² = 1²+2²
a² + b² = 1+4
a² + b²= 5
a² + b² ≠ c²
This is also not forming a Pythagorean Triple, that is why incorrect.
(D) {14, 48, 50}
c = 50, a = 14, b = 48
a² + b² = (14)²+(48)²
a² + b² = 196 +2304
a² + b² = 2500
a² + b² = (50)²
a² + b² = c²
This satisfies the condition (1) hence, it is forming a Pythagorean Triple.
This option is an appropriate choice.
Hence, option (D) is correct, that means {14, 48, 50} represents a Pythagorean Triple.
