Answer:
The change received by Judy is $ 2.69.
Step-by-step explanation:
Bill paid = $ 10
Cost of binder = $ 1.38
Cost of pack of pencils = $ 2.05
Cost of box of erasers = $ 3.88
Total cost of the school supplies = $ 1.38 + $ 2.05 + $ 3.88 = $ 7.31
The amount of change Judy received = $ 10 - $ 7.31 = $ 2.69
Find the slope for the 4 problems
Need help ASAP!
NO LINKS!!
Answer:
1: m = 2
2: m = -1
3: m = 7/8
4: m=0
Step-by-step explanation:
Before I begin, ALWAYS REMEMBER, the slope formula is:
y2 - y1 / x2 - x1 = slope
1:
(4,4) (6,8)
y2: 8
y1: 4
x2: 6
x1: 4
8-4 / 6-4 = 4/2 = 2
2:
(6,1) (4,3)
y2: 3
y1: 1
x2: 4
x1: 6
3-1 / 4-6 = 2/-2 = -1
3:
(4,1) (12,8)
y2: 8
y1: 1
x2: 12
x1: 4
8-1 / 12-4 = 7/8
4:
(8,3) (8,2)
y2: 2
y1: 3
x2: 8
x1: 8
2-3 / 8-8 = -1/0 = 0

Answer:
2) Slope=10/3
Step-by-step explanation:
2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3
4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.
Which bottle was the better bargain?
Answer:
The 4 pint ketchup bottle was the better bargain.
Step-by-step explanation:
To find which bottle was the better bargain, find which one had the most amount of ketchup in it.
In one quart, there are 2 pints.
Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:
1.25(2)
= 2.5
Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.
So, the 4 pint ketchup bottle was the better bargain.

Therefore the cost per round of the chicken can be calculated as follows
9÷5/2
= 9×2/5
= 18/5
= 3 3/5
i got A is that right??
Answer:
Yes
Step-by-step explanation:
To fins the area if the rectangle you need to find the hypotenuse of the triangles, which are equal. so 10.4 squared plus 15.3 squared is 342.25, and the square root is 18.5.
Then, 18.5 multiplied by 7 is 129.5. Then to fins the area of a triangle you need to do it like a rectangle but in this case, sense there are 2, then just find the area. 129.5+(10.4 times 15.3=159.12)=129.5+159.12=288.62

yes

There is 1/3 of a pizza left to split between 3 of your friends. If you split the pizza equally. What fraction of the pizza will each of your friends get.
Answer:
Each friend will get 1/9 of the pizza (I think).
Step-by-step explanation:
I believe you would divide 1/3 by 3, or in other words, multiply 1/3 * 1/3:
1/3 * 1/3 = 1/9

Solve the following:
A man borrowed a Rs 5000 from a money lender for 5 years at the rate of 8% per annum. How much interest did he pay for 5 years? Also find the amount.
Answer:
Interest = Rs 2000
Amount = Rs 7000
Step-by-step explanation:
Amount = Principal + Interest
Given
Principal = Rs 5000
Interest= PRT/100
Interest = 5000*8*5/100
Interest = 50*40
Interest = Rs 2000
Amount after 5years = 5000 + 2000
Amount after 5years = Rs 7000

The area of a rectangular window is 8217 cm
If the length of the window is 99 cm, what is its width?
Find the area of the figure below. * 23 cm 12 cm 18 cm 15 cm
The area of the figure = area of trapezium + area of rectangle = 420 cm².
What is the Area of a Trapezium and Area of a Rectangle?Area of trapezium = 1/2(a + b)h
Area of rectangle = length × height.
The area of the figure = area of trapezium + area of rectangle
The area of the figure = 1/2(a + b)h + length × height
Plug in the values
The area of the figure = 1/2(23 + 15)6 + 23 × 12
The area of the figure = 144 + 276
The area of the figure = 420 cm²

https://brainly.com/question/16904048
Answer: The area is 390 cm
Step-by-step explanation:
All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.
Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h
base 1 = 15 cm
base 2 = 23 cm
height = 6 (18-12)
so, 15 + 23 = 38
38 x 6 = 228
228 x 0.5 or 1/2 = 114
Therefore the area of the trapezoid is 114 cm
Area of rectangle formula: A = bh
base = 23
height = 12
12 x 23 = 276
Therefore the area of the rectangle is 276 cm
Now add the values together, 114 + 276 = 390
390 is the area of the figure

Using the Pythagorean theorem what is the distance between (5,-3) and (9,1)
Step-by-step explanation:
Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2
=√4^2+4^2
=√16+16
=√32 units
It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2
The graph of a function is shown below. yeah
Which value is not in the range of the function?
Answer:
There is no graph included.

Diego’s family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less.
b. Starting from a full tank, can Diego’s family drive the car for 25 days without the warning light coming on?
Explain your answer.
Answer: no
Step-by-step explanation:
if diego car can hold 14 gallons and eveery day they use 0.6 0.6x25 is 15 which means that they can drive 15 days in all so 15-1.5 13.5 so they can only drive for 13.5 days
hope this helps :)
Answer:
No, Diego's family cannot drive the car for 25 days without the warning light coming on.
Step-by-step explanation:
Find how much fuel they will use in 25 days by multiplying 25 by 0.6, since the car uses 0.6 gallons each day:
25(0.6)
= 15
Subtract this from 14 to see how much fuel will remain, starting from a full tank:
14 - 15
= -1
The number is negative, meaning that driving the car for 25 days will use up all of the fuel. So, the warning light will come on.
No, Diego's family cannot drive the car for 25 days without the warning light coming on.

The area of a rectangle is (81x2 − 4y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
Answer:
The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.
Step-by-step explanation:
Geometrically speaking, the area of a rectangle is equal to the product of its base and its height. If we know that area of the figure is [tex]81\cdot x^{2} - 4\cdot y^{2}[/tex] square units, then we proceed to factor the expression:
1) [tex]A = 81\cdot x^{2} - 4\cdot y^{2}[/tex] Given
2) [tex]A = (9\cdot x -2\cdot y)\cdot (9\cdot x + 2\cdot y)[/tex] [tex]a^{2} - b^{2} = (a + b) \cdot (a - b)[/tex]/Result
The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.
Answer:
(9x + 2y)(9x - 2y)
Step-by-step explanation:
The rule: a^2 - b^2 = (a + b)(a - b)
81x^2 - 4y^2
And we have a = 9x and b = 2y
and our factors are.
(9x + 2y)(9x - 2y)
so the the dimensions are 9x + 2y and 9x - 2y
