The ratio of nickels to dimes to quarters is given as ...
N : D : Q = 6 : 1 : 4
The total number of ratio units is 6 +1 +4 = 11. The total number of coins is given as 99, so each "ratio unit" must represent 99/11 = 9 coins. That is, the actual coin count ratios are ...
N : D : Q = 54 : 9 : 36
Zachary has 54 nickels, 9 dimes, and 36 quarters.

Answer: y > x + 4
Step-by-step explanation:
First lets find a linear equation for the dividing line, in the form:
y = mx + b
We know that b is 4, since this is the y-intercept
lets use any point on the graph, I'll use (-4, 0):
y = mx + 4
0 = m(-4) + 4
-4 = -4m
m = 1
So the slope is 1. Our completed formula for the line is:
y = x + 4
Since the left side of this graph is shaded, we know it will either be > or ≥. Since the line is also dotted we know it is denoted by a simple ">" sign.
So our completed inequality equation is: y > x + 4
Hope this helped!
Answer:
[tex]\sf y > x+4[/tex]
Step-by-step explanation:
Choose 2 points on the line: (-4, 0) and (0, 4)
Let [tex]\sf (x_1,y_1)=(-4,0)[/tex]Let [tex]\sf (x_2,y_2)=(0,4)[/tex][tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-0}{0-(-4)}=1[/tex]
point-slope form of linear equation: [tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-0=1(x-(-4))[/tex]
[tex]\implies \sf y=x+4[/tex]
Solid line : ≤ or ≥
Dashed line: < or >
Therefore as the line is dashed, and the shading is above the line,

(PLS HELP)The diameter of a cylindrical water tank is 12 ft, and its height is 17 ft. What is the volume of the tank?
Use the value 3.14 for л, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer: The volume is equal to 1922.65.
Step-by-step explanation:
Diameter is 12 ft, height is 17 ft.
V = πr2h
V = πr2h = π·62·17≈ 1922.65
The volume of the tank is approximately 1814 cubic feet.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The formula for the volume of a cylinder is:
V = πr²h
where V is the volume, r is the radius, h is the height, and π is a constant equal to approximately 3.14.
We are given the diameter of the tank, which is 12 feet.
The radius is half the diameter, so:
r = 12/2 = 6 feet
We are also given the height of the tank, which is 17 feet.
Substituting these values into the formula, we get:
V = πr²h
V = 3.14 × 6² × 17
V ≈ 1814
Therefore,
The volume of the tank is approximately 1814 cubic feet.

Solve for T
V = x + at
Answer:
t=V‒x/a
Step-by-step explanation:
V=x+at (add ‒x in both side)
V‒x=x+at‒x
V‒x=at
V‒x/a=at/a
V‒x/a=t
so the formula is t=V‒x/a
Alice was having a conversation with her friend Trina, who had a discovery to share:
Pick any two integers. Look at the sum of their squares, the difference of their squares,
and twice the product of the two integers you chose. Those three numbers are the
sides of a right triangle.
a. Write an equation that models this conjecture using the variables x and y.
b. Investigate this conjecture for at least three pairs of integers. Does her trick
appear to work in all cases, or only in some cases? Explain.
c. Use Trina’s trick to find an example of a right triangle in which all of the sides
have integer length, all three sides are longer than 100 units, and the three side
lengths do not have common factors.
BONUS: If Trina’s conjecture is true, use the equation found in part a to prove the
conjecture. If it is not true, modify it so it is a true statement, and prove the new
statement
Answer:
a. (x² + y²)² = (x² - y²)² + (2xy)²
b. The conjecture works in all cases.
c. Sides of 119, 120, and 169
Step-by-step explanation:
a. Equation that models this conjecture
x² + y² = sum of squares
x² - y² = difference of square
2xy = twice the product of the integers
If these are the sides of a right triangle then
(x² + y²)² = (x² - y²)² + (2xy)²
b. Test the conjecture
(i) Try x = 2, y = 1
(2² + 1²)² = (2² - 1²)² + (2×2×1)²
5² = 3² + 4²
25 = 9 + 16
(ii) Try x = 3, y = 1
(3² + 1²)² = (3² - 1²)² + (2×3×1)²
10² = 8² + 6²
100 = 64 + 36
(iii) Try x = 3, y = 2
(3² + 2²)² = (3² - 2²)² + (2×3×2)²
13² = 5² + 12²
169 = 25 + 144
The conjecture appears to work in all cases.
c. A possible triangle
We must have one side greater than 100. That means,
x² > 100 or x >1 0.
Let x = 12
One side = 12² + y²
The second side = 12² - y²
The third side must have 2xy > 100
24y > 100
y > 4.2
Try y = 5
(12² + 5²)² = (12² - 5²)² + (2 × 12 × 5)²
169² = 119² + 120²
So, one right triangle could have sides of 119, 120, and 169.
Furthermore, these sides have no common factors.
Check:
169² = 119² + 120²
28561 = 14161 + 14400
28561 = 28561

What value belongs next to the 1 in the table? What does it mean in this context?
Answer:
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)
Step-by-step explanation:
The value next to 1 in the table above = number of dimes we have in 1 quarter.
Let the value next to 1 be "x".
That is:
1 quarter = x dimes
If 4 quarters = 10 dimes, then,
Cross multiply to find, how many dimes, x is equal to.
Thus:
1*10 = 4*x (cross multiplication)
10/4 = 4x/4 (dividing both sides by 4)
2.5 = x
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)
