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.

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

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

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.
