Which mapping diagram represents a function ? Would it be D?
Answer:
D
Step-by-step explanation:
Mathematically , for us to have a function, no 2 y values must have a single x value
Although, 2 x-values can have a single y value
The y values called the output values are listed on the right
The x values called the input values are listed on the left
So out of the options, with the given definition above, the one that represents a function is the option D

Go to le
The sample space below shows the results of the final eight matches played by the English soccer team
Manchester United during their championship 2012 - 2013 season. They won matches where they scored
more goals than their opponent, lost matches where they scored less, and tied matches where they scored the
same amount.
If we take matches 1, 2, 4, 6, and 7 as a subset of the sample space, which of the statements below describe
this subset?
Choose all answers that apply:
CA
The subset consists of all the matches where Manchester United's opponent did not win.
B)
The subset consists of all the matches where Manchester United won or lost.

B) The subset consists of all the matches where Manchester United won or lost.
Step-by-step explanation:
1 - Manchester united lost
2 - Manchester United won
4 - Manchester United won
6 - Manchester United lost
7 - Manchester United won
Hence, 1, 2, 4, 6, 7 consists of matches where Manchester United either won or lost.
Therefore, 1,2,4,6,7 is a subset of the sample space where Manchester United won or Lost

D
Step-by-step explanation:
Answer:
the answer is: parallelograms are quadilaterals
there are two machines that can produce aluminum cans. The newer machine can produce 5400 cans in 180 minutes. It takes the older machine 217 minutes produce that many cans. If the two machines work together, how long will it take them to produce 5400 cans?
The newer machine works at a unit rate of
(5400 cans) / (180 min) = 30 cans/min
while the older machine operates at
(5400 cans) / (217 min) ≈ 24.88 cans/min
So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about
(5400 cans) / (54.88 cans/min) ≈ 98.39 min

Javier estimates the square root of 18 in the following way:
18−−√=29–√=2∗3=6
18=29=2∗3=6
Explain why her reasoning is incorrect.
Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.
Answer:
The square root will be about 4 because the formula for square root is √(x^2) = x
Step-by-step explanation:
Answer:
√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.
4x4 = 16
5x5 = 25
so √18 is between 4 and 5. closer to 4

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1100 miles, for a total gas consumption of 35 gallons. How many gallons were consumed by each of the two cars that week?
Answer:
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.
Step-by-step explanation:
fuel efficiency = distance in miles/gallons of gas
fuel efficiency * gallons of gas = distance in miles
Car 1: 20 mpg
Car 2: 40 mpg
Total miles: 1100
Miles of Car 1: x
Miles of Car 2: 1100 - x
Total gallons: 35
Gallons for Car 1: y
Gallons for Car 2: 35 - y
Car 1:
fuel efficiency * gallons of gas = distance in miles
20 * y = x
Car 2:
fuel efficiency * gallons of gas = distance in miles
40 * (35 - y) = 1100 - x
20y = x
1400 - 40y = 1100 - x
20y = x
x = 40y - 300
40y - 300 = 20y
20y = 300
y = 15
35 - y = 35 - 15 = 20
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.

∛44x-7 -5=0 find the x
Answer:
x = 3.
Step-by-step explanation:
(∛44x - 7) - 5 = 0
Cube the expression.
44x - 7 - 125 = 0
Subtract.
44x - 132 = 0
Add 132 to both sides.
44x = 132
Divide by 44.
x = 3.
Proof:
(∛44x - 7) - 5 = 0
(∛44(3) - 7) - 5 = 0
(∛132 - 7) - 5 = 0
(∛125) - 5 = 0
5 - 5 = 0
0 = 0

Question 5: The missing term her is r²
Question 6: The missing term here is 3.
Step-by-step explanation:
Question 5:
Let's write the equation and then solve it for the missing term. We will call this term x.
[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]
First, we simplify the letf term adding the similar terms.
[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]
Now, we substract 4r⁴ and 7r in both sides.
[tex]x=r^{2}[/tex]
Therefore, the missing term her is r²
Question 6:
Here, we will call the missing term y. Now, let's solve it for y.
[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]
Let's first distribute the minus sign into the parentehsis.
[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]
Now simplify the left side by adding similar terms.
[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]
Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.
[tex]y=10-7[/tex]
[tex]y=3[/tex]
Therefore, the missing term here is 3.

What’s the value of x?
Explain
Answer:
There is no x, so I’ll find y
Step-by-step explanation:
-4(y-2)=12
Multiply -4 with y and -2
-4y+8=12
Then subtract 8 with its self and 12
-4y = 4
now divide both numbers with 4

A cylindrical pipe is 25 ft long and has a volume of 900ft3 find it's approximate diameter to the nearest hundredth of a foot
Answer:
Diameter of the pipe ≈ 6.77 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
Here, r = Radius of the cylindrical pipe
h = Length of the pipe
Volume of the pipe = 900 ft³
Length of the pipe = 25 ft
By substituting the given values in the formula,
900 = π(r)²(25)
r² = [tex]\frac{900}{25\pi}[/tex]
r = √11.459
r = 3.385
Diameter = 2(radius)
= 2(3.385)
= 6.77 ft
The diameter of the cylinderi is 6.77ft
Volume of a cylinderthe formula for calculating thevolume of a cylinder is given as
V = pi d²/4 × h
Given the following
V = 900ft³
h = 25ft
Substitute the given parameters
900 = 3.14 × d²/4 × 25
900 = 19.625d²
d² = 45.859
d = 6.77ft
Hence the diameter of the cylinderi is 6.77ft
