Suppose x, y, and z are different positive integers such that xy, yz, and zx are all perfect
squares. Must x, y, and z be perfect squares? Why or why not?
Answer: Yes, and the numbers are 4, 36, and 9
Step-by-step explanation:
Yes, because it x=4, y=36, and z=9 then 4 * 36=144, 144=12*12 4*9=36, 36=6*6, and 9*36=324, 324=18*18. As you can see they are all perfect squares and 4, 36, and 9 are all perfect sqaures too.
Can someone help with this. Heads up it's ratios
Answer:
The median side measures 92 yards
Step-by-step explanation:
Let's call x, y, and z the measures of the sides of the triangle.
The ratios between them are:
[tex]\displaystyle \frac{x}{y}=\frac{4}{7}[/tex]
[tex]\displaystyle \frac{x}{z}=\frac{4}{2}=2[/tex]
The first ratio gives the relation:
[tex]\displaystyle y=\frac{7x}{4}[/tex]
The second ratio can be solved for z:
[tex]\displaystyle z=\frac{x}{2}[/tex]
Since the perimeter is 299 yards:
[tex]x+y+z=299[/tex]
Substituting the above relations:
[tex]\displaystyle x+\frac{7x}{4}+\frac{x}{2}=299[/tex]
Multiplying by 4:
[tex]4x + 7x+2x=1196[/tex]
Joining like terms:
[tex]13x=1196[/tex]
Dividing by 13:
[tex]x=1196/13[/tex]
x=92
Now calculate y:
[tex]\displaystyle y=\frac{7\cdot 92}{4}[/tex]
y = 161
[tex]\displaystyle z=\frac{92}{2}[/tex]
z=46
The median side measures 92 yards
What is the value of x if 5^x+2 =5^9
Answer: 7
Step-by-step explanation: If they equal each other, then that must mean that the exponents equal. Therefore, we can draw out the conclusion that x+2=9, which is x=7
help math pls geometry
Answer:
The point is (8,2)
Step-by-step explanation:
Is this a square or rectangle or rhombus, etc.? Yes, because all the lines are all parallel.
Are AB and FG are parallel to each other right? Yes, so that means whatever you do to F will happen to G and we can start on A, it goes 6 down, then two to the right.
Since all lines are parallel how many steps we do on A to get F, we have to do to B to get G. So, (8,2).

A fireman is on the middle step of a ladder. (There are the same number of steps above him as below him.) If he goes down 4 steps, then up 7 steps, and then down 13 steps, he will be on the first step above the ground. How many steps does the ladder have?
Answer:
The ladder has 20 steps
Step-by-step explanation:
10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.

Snowy Mountain in Alaska has an elevation of 7,093 feet. Together, Snowy
Mountain and Mammoth Mountain in California have a combined elevation of
18, 152 feet. What is the difference in elevation between Snowy Mountain and
Mammoth Mountain?
The difference in elevation between Snowy Mountain and Mammoth Mountain is
feet.
Answer:
11,059
Step-by-step explanation:
If you take the combined elevation (18,152) and subtract the elevation of Snowy Mountain (7,093), you should get 11,059.
Answer:
I believe 3966
Step-by-step explanation:
18152-7093=11059
11059-7093=3966
manuel calculates the business costs and profits to produce and hiking backpacks. manuel's profit is his revenue minus his expenses.
A. Write a function to present the profit Manuel makes selling n backpacks.
B. Graph the profit function. What is a reasonable domain for this function for one year if his revenue is between $4,000 and $30,000? Is the function discrete or continuous? Explain
C. How much is his profit if he sells 43 backpacks? Explain
setup cost is $5,250 assembly cost is $54/ backpack revenue is $159/ backpack
Answer:
A. P = n × $105 - $5,250
B. Please find attached the required graph
The domain for the range ($30,000 to $4,000) = 25 < n < 189
C. The profit from selling 43 backpacks = -$735
Step-by-step explanation:
A. The given parameters are;
The setup cost = $5,250
The assembly cost = $54/backpack
The revenue = $159/backpack
Let n represent the number of backpack produced
Therefore, we have;
Profit, P = $ 159 × n - $54 × n - $5,250
P = n × ($ 159 - $54) - $5,250 = n × $105 - $5,250
P = n × $105 - $5,250
B. Please fins attached the graph of the profit function, created with Microsoft Excel
The domain for a range of revenue of $30,000 to $4,000 is given as follows;
The domain for the range ($30,000 to $4,000) = 25 < n < 189
C. The amount of profit from selling 43 bags = P(43) = 43 × $105 - $5,250 = -$735
urgent!! hal earns $5 doing chores for his parents. he also earns $10 a week for each dog, d, he walks.
Answer:
5+10d=x The dogs he walks are the ind variable and the total money he earns is the dep variable
Step-by-step explanation:
If he earns five dollars a week then that is a confirmed amount which means it’s just $5. Then for every dog he walks that’s $10 so if he walks 0 dogs then he gets $0.
The dogs he walks is ind because this variable is the variable that changes and effects the total whereas, the dep is the total because that’s what changes depending on the ind variable

A real estate agent earned commission of $8,785 for selling a house. If his rate is 7%, find the selling price of the house.
Answer:
$125,500
Step-by-step explanation:
Make "x" equal the selling price of the house
7% of x is the commission --->
.07 * x = 8785
x= 8785/ .07
x= 125500
plzzz help find the missing length indicated????
Answer:
The missing length is 64
Step-by-step explanation:
In the given figure
∵ The triangle is a right triangle
∵ There is a line drawn from the right angle ⊥ to the hypotenuse
→ There is a relation between the side of length 60, the part of the
length 36, and the length of the hypotenuse
∵ The length of the hypotenuse = x + 36
∴ (60)² = 36 × (x + 36)
→ Multiply the bracket by 36
∴ 3600 = 36(x) + 36(36)
∴ 3600 = 36x + 1296
→ Subtract 1296 from both sides
∵ 3600 - 1296 = 36x + 1296 - 1296
∴ 2304 = 36x
→ Divide both sides by 36 to find x
∴ 64 = x
∴ The missing length is 64

One base of a trapezoid is five times as long as the other. The height is the average of the two bases. The area is 441 square units. Find the length of the longer base.
Answer:
The length of the longer base he 35 units
Step-by-step explanation:
Here, we want to find the length of the longer base of the trapezoid
Mathematically, we can find the area using the formula;
1/2( a + b) h
where a is the shorter base
b is the longer base
h is the height
Let the shorter base be x
The other base is 5 times this length and that makes 5 * x = 5x
Height is the average of both bases;
(x + 5x)/2 = 6x/2 = 3x
Substituting these in the formula, we have ;
1/2(x + 5x)3x = 441
3x(6x) = 882
18x^2 = 882
x^2 = 882/18
x^2 = 49
x^2 = 7^2
x = 7
But the longer base is 5x and that will be 5 * 7 = 35 units

What is the valur of y in the equation 2(3y - 6) = 0?
Answer:
y=2
Step-by-step explanation:
Distribute the 2 into 3y and -6:
6y-12=0
Move the -12 to the other side by adding both sides by 12:
6y-12+12=0+12
=
6y=12
divide both sides by 6:
y=2
