Answer:
20, for 8.50
Step-by-step explanation:
6 + 6 = 12, which is 4.50 + 4.50, which would be about 10, so 20 for 8.50 would be better.
How to find if it is a function or not:
The set of ordered pairs (Z,A) where z is the zip code, and A is the street address.
Answer: It is not a function.
Step-by-step explanation:
A function is something that "eats" an input and transforms it into an output.
We write them as y = f(x)
Where x is the input, and y is the output.
Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.
This means that, for example, if we have, for x = x1.
And a single
f(x1) = y1
f(x1) = y2
where y1 and y2 are different values.
Then this is not a function, because it is mapping the value x1 into two different outputs.
In this case, we would have:
f(Z) = A.
So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.
This means taht the set (Z, A) can not represent a function.

A globe has a diameter of 14 inches. Find the volume of the globe. Round your answer to the nearest tenth.
Answer:
1436.8 in³ (nearest tenth)
Step-by-step explanation:
A globe is in the shape of a sphere.
[tex]volume \: of \: sphere = \frac{4}{3} π {r}^{3} [/tex]
Diameter= 2 ×radius
radius of globe
= 14 ÷2
= 7 inches
Volume of globe
[tex] = \frac{4}{3} π {(7}^{3} ) \\ = 1436.8 \: in^{3} \\ (nearest \: tenth)[/tex]
Step-by-step explanation:
We have given that diameter of globe (sphere) is 14 inches,Then it's radius is 14/2 = 7 inches :]To find the volume of sphere we have to use the given below formula :]
[tex] \boxed {\underline{ \underline{\bigstar\:\: \sf Volume \: of \: sphere = \dfrac{4}{3} \pi r^3 \: \: \bigstar}}} \\ \\ [/tex]
☯ [tex]\underline{\boldsymbol{According\: to \:the\: Question\:now :}} [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 7 \times 7 \times 7 \: \: \bigg \lgroup \bf{putting \: \pi = 3.14} \bigg \rgroup \\ \\ [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 343 \\ \\ [/tex]
[tex]: \implies \underline{ \boxed{ \sf Volume \: of \: sphere = 1436.0267 \: cubic \: inches}} \\ [/tex]

if it is 2:30 what time would it be 1 hour and 30 minutes
Answer:
4:00
Step-by-step explanation:
what is the smallest two digit positive integer such that the product of its two digits is one-half the integer
Let x be the tens and y be the ones digits.
The product of the number is then: 10x + y
The product is 1/2, so you need to multiply the product by 2 and the number:
10x + y = 2(x+y)
10x + y = 2x + 2y
Subtract 1 y from both sides
10x = 2x + y
Subtract 2x from
Both sides
8x = y
X has to be 1 , which would make y 8
The product number becomes 18
Since the product is 1/2, multiply by 2:
18 x 2 = 36
3 x 6 = 18
The answer is 36

Use the graph below to fill in the blank with the correct number: (1 point)
f(1) =
Answer:
f(1) = -2
Step-by-step explanation:
Remember that when dealing with functions, it is written in the form of f(x)
We know that f(1) is the value of the function when the value of x is equal to 1
In this problem, look on the graph to see
for x = 1
the value of the function is f(1) = -2
Answer:
-2
Step-by-step explanation:
Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the
towns can be represented by four points: A, G, M, and W. Given that M is the midpoint of AW and MG =
MA + GA, determine the
proper order of the four towns.
Answer:
W, M, A and G
Step-by-step explanation:
The question is not correct, the correct question is Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the towns can be represented by four points: A, G, M, and W. Given that MG + WM = WG and MA = MG - AG determine the proper order of the four towns.
Answer: The line segment addition postulate states that for a line segment AC with point B which lines on AC, then this equation holds:
AB + BC = BC
Given that MG + WM = WG, this means that point M lies between the segment WG.
Also, MA = MG - AG
MA + AG = MG, hence point A lies between segment MG
Therefore the order of the points is W, M, A and G
The density of a substance can be found by dividing the mass of the substance by the volume of the substance. A sheet of pure iron has a mass of 500 grams and a volume of 4 in3.

Round your answer to 2 decimals.
9f = {(12f – 2)
Answer:
f=0.67
Step-by-step explanation:
Let's solve your equation step-by-step by isolating f.
9f=12f−2
Step 1: Subtract 12f from both sides.
9f−12f=12f−2−12f
You get:
−3f=−2
Step 2: Divide both sides by -3.
−3f/−3 = −2/−3
You get:
f= 2/3, or f= 0.67

[tex]Explanation:[/tex]
[tex]2xy-xz=4[/tex] Solve for X
x(2y - z) Factor out the variable x
x(2y - z)/2y - z = 4/2y - z Divide both sides by 2y - z

4 b + 19 can be translated as "nineteen more than the product of 4 and a number." TrueFalse
Answer:
True
Step-by-step explanation:
Step-by-step explanation:
4b+19
If 19 is added to 4b, then yes, it is 'nineteen more than...'
4b is a multiplication expression in itself and the term 'product' means the answer to a multiplication problem.
So the answer is true.
