Answer:
(1, -1), (1, -2), (2, -3), (2, -4)
NO
Step-by-step explanation:
✔️Each ordered pair is written as (input, output).
Thus, we would have the following:
(1, -1), (1, -2), (2, -3), (2, -4)
✔️This cannot be a function because every input value do not have exactly one output value related to it. A function should not have an input value related to more than one output value.
So, the answer is NO. It is not a function.
Why is 2/10 equivalent to 1/5?
Answer:
If you divide both top and bottom of [tex]\frac{2}{10}[/tex] by 2, you get [tex]\frac{1}{5}[/tex]
Answer:
because you have to find common denominators
2/10= 1/5
2/10= 1x2/5x2
Whatever you do to the bottom, you do to the top so that is why i also multiplied the numerator by 2.
2/10=2/10

Is 15 ft 20 ft 24 ft a right triangle
Answer:
No
Step-by-step explanation:
If:
a=15
b=20 then
c (hypotenuse)=25
Answer:
No
Step-by-step explanation:
A right angle is always 90°
u add up all the sides, if it doesn't equal 90 then it's not a right triangle.
so 15 + 20 + 24 = 59 so this is not a right triangle.

The size of a jar of coffee is increased by one 1/5. The new size is later reduced by 1/5
Is the new jar smaller, the same size or larger than the original?
Answer:
The new jar would be smaller than the original.
Step-by-step explanation:
First you would have to find one 1/5 of the original size. This gives you the increased size.
Then, you'd find 1/5 of the new size and subtract it from the increased size of the jar.
1/5 of the increased size is larger than 1/5 of the original size, so no matter what number it is, you'll always end up with a smaller-sized jar of coffee at the end.
The new jar would be smaller than the original.
What is the scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.
First, you would have to find one 1/5 of the original size. This gives you the increased size.
Then, you'd find 1/5 of the new size and subtract it from the increased size of the jar.
1/5 of the increased size is larger than 1/5 of the original size, so no matter what number it is, you'll always end up with a smaller-sized jar of coffee at the end.

Answer:
If the total price of an object is A, and we have a tax of X%, then the new price of the object is:
Price = A + A*(X%/100%) = A*(1 + X%/100%)
In this case, the initial price of the car is:
A = $16,368
a) the tax is 6.6%
In this case, the price will be:
Price = $16.368*(1 + 6.6%/100%) = $17,448.288
b) the tax is 8.25%
In this case, the price will be:
Price = $16.368*(1 + 8.25%/100%) = $17,718.36
c) the tax is r.
we only replace X% by r.
Price = $16.368*(1 + r/100%)
d) We want to solve for r the above equation, we just need to isolate r.
Price/( $16.368) = (1 + r/100%)
Price/($16.368) - 1 = r/100%
(Price/($16.368) - 1)*100% = r

Sarah buys 8 packages, each with 20 balloons, and uses 1/4 of them to decorate the hall.
Write and evaluate an expression to find how many balloons Sarah has left.
Answer:
(8 × 20) ÷ 4
40
Step-by-step explanation:
8 × 20 = 160
160/4 = 40
The fraction is defined as a number in the form of a/b where a nd b are integers and b is not equal to zero. Sarah has left with 120 balloons.
What is a Fraction?A fraction is used to represent a portion or part of anything. It consists of two parts a numerator and a denominator. For example 1/4 is a fraction where numerator is 1 and denominator is 4.
The total number of packages = 8
Number of balloons in each package = 20.
The portion of balloons use to decorate hall = 1/4.
Suppose the remaining balloons are x.
Thus the expression for remaining balloons can be written as,
x = 20 × 8 - 1/4×(20 × 8)
x = 160 - 40
= 120.
Hence, Sarah has left with 120 balloons and the expression for left balloons is x = 20 × 8 - 1/4×(20 × 8).

David canoes 20km downstream in 2.5 hours his return trip takes 4 hours find the rate of his current. A 1.5 km/h B 1 km/h C 0.5 km/h D 2.5 km/h
Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour
There are 7 trucks for every 5 cars . If there are 21 trucks, how many cars are there?
Answer:
15 cars

If there are 7 trucks for every 5 cars, the ratio is 7:5. So if there are 21 trucks, that's 7 x 3, which means we also multiply 5 by 3 = 15
a cylindrical water tank has a diameter of 4m and a height of 3m.while a water tank shaped like a rectangular prism has a length of 7m.a width of 2 meters and a height of 2 meters. which of the tanks can hold more water? by how many cubic meters?
Answer:
The cylindrical tank can hold 9.7 cubic meter more water than the rectangular prism shape tank .
Step-by-step explanation:
We are given that
Diameter of cylinderical water tank, d=4 m
Radius of cylinderical water tank,r=d/2=4/2=2 m
Height of cylinderical water tank,h=3 m
Length of rectangular prism, l=7 m
Width of rectangular prism ,w=2 m
Height of rectangular prism, h=2m
Volume of cylinder=[tex]\pi r^2 h[/tex]
Where [tex]\pi=3.14[/tex]
Using the formula
Volume of cylinderical tank=[tex]3.14(2)^2\times 3=37.7m^3[/tex]
Volume of rectangular prism=[tex]lwh[/tex]
Using the formula
Volume of rectangular prism=[tex]7\times 2\times =28m^3[/tex]
Difference between volumes=37.7-28=9.7 cubic meters
Hence, the cylindrical tank can hold 9.7 cubic meter more water than the rectangular prism shape tank .

Answer:
The factored expression is: [tex]2x(x + 3)[/tex]
Step-by-step explanation:
We are given the following expression:

To factorize it as fully as possible, we first find the GCF between the numeric values, and the coefficients:
Numeric:
GCF between 2 and 6 is 2, because:
2 - 6| 2
