Fernando has 22 coins consisting of nickels and dimes in his pocket,
The total value of the coins is $1.70
which system of equations can be used to determine the number of
nickels, n, and the number of dimes, d, in his pocket? ANSWER CHOICES IS IN THE PICTURE
Answers
Answer:
the lat one should be the right answer
Step-by-step explanation:
The equation that can be used to represent the situation will be:
0.05n + 0.10d = 1.70n + d = 22Let the number of nickels be represented by n.
Let the number of dimes be represented by d
Therefore, since Fernando has 22 coins consisting of nickels and dimes in his pocket and the total value of the coins is $1.70.
The equation that can be used to represent the situation will be:
0.05n + 0.10d = 1.70
n + d = 22

The graph of a quadratic equation in two variables whose axis of symmetry is parallel to the y axis is a parabola.
Select one:
True
False
Answers
Answer:
The correct option is;
False
Step-by-step explanation:
The equation of the graphs of conic sections (all of which can have axis of symmetry that can be oriented parallel to the y-axis) includes;
Circle; (x - h)² + (y - k)² = r²
Parabola; y = a·(x - h)² + k
[tex]Ellipse; \dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
[tex]Hyperbola; \dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
The graph of a quadratic equation in two variables whose axis of symmetry is parallel to the y-axis can be either a circle, a parabola, an ellipse, or an hyperbola
Therefore, the graph may not be the graph of a parabola and the statement is false

Plug in values into your formula
SA = 2•pi•r^2 + 2•pi•r•h
SA = 2•pi•3^2 +2•pi•3•8
Height (h) = 8in.
Radius (r) = 3 (diameter divided by 2)
Diameter = 6
SA = 2πr^2 + 2πrh
Where SA means surface area, r stands for radius, and h stands for height.
First find the radius. The radius of a circle is the distance from the outside of the circle to its center. It is half the diameter. To find the radius, divide the diameter by two.
r = 6/2
r = 3 inches
Now plug in the values for radius and height into your formula. Use pi = 3.14
SA = 2(3.14)r^2 + 2(3.14)rh
SA = 2(3.14)(3)^2 + 2(3.14)(3)(8)
SA = 6.28(9) + 6.28(24)
SA = 56.52 + 150.72
SA = 207.24 inches

Part A= 12 x ? = ? ft²
Part B= 0.5 x ? x 9 = ?ft²
Part C= 0.5 x 7 x ? = ?ft²
Total Area= ?ft²
Answer:
[tex]A = 108ft^2[/tex]
[tex]B = 27ft^2[/tex]
[tex]C = 24.5ft^2[/tex]
[tex]Area = 159.50ft^2[/tex]
Step-by-step explanation:
Given
See attachment
From the attachment;
Part A is a rectangle with dimension 9ft by 12ft
So,
[tex]A = 12ft * 9ft[/tex]
[tex]A = 108ft^2[/tex]
Part B is a triangle with dimension: height = 6 and base = 9
The height is calculated as:
[tex]Height = 12ft - 6ft = 6ft[/tex]
And the base is:
[tex]Base = 18ft - 9ft = 9ft[/tex]
So, the area is:
[tex]B = 0.5 * 6ft * 9ft[/tex]
[tex]B = 27ft^2[/tex]
Part C is a triangle with dimension: height = 7 and base = 7
So, the area is:
[tex]C = 0.5 * 7 * 7ft^2[/tex]
[tex]C = 24.5ft^2[/tex]
Total Area is:
[tex]Area = A + B + C[/tex]
[tex]Area = 108ft^2 + 27ft^2 + 24.5ft^2[/tex]
[tex]Area = 159.50ft^2[/tex]

1 A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10
centimeters. Which measurement is closest to the total surface area of the can in
square centimeters?
Answers
Answer:
radius r = 3 cm
height h = 10 cm
volume V = 282.743339 cm^3
lateral surface area L = 188.495559 cm^2
top surface area T = 28.2743339 cm^2
base surface area B = 28.2743339 cm^2
total surface area A = 245.044227 cm^2
In Terms of Pi π
volume V = 90 π cm3
lateral surface area L = 60 π cm^2
top surface area T = 9 π cm^2
base surface area B = 9 π cm^2
total surface area A = 78 π cm^2
Step-by-step explanation:
Cylinder Formulas in terms of r and h:
Calculate volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside)**:
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
Agenda: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
The value of Surface Area of the cylinder is 245.04 cm².
What is Surface Area of a shape ?Surface area is the amount of space covering the outside of a three-dimensional shape.
It is given that the cylinder has
radius r = 3 cm
height h = 10 cm
volume V of the cylinder = πr²h = 282.74 cm³
the lateral surface area of a cylinder
L = 2πrh
lateral surface area L = 188.495559 cm²
the top and bottom surface area of a cylinder (2 circles):
T = B = πr²
top surface area T = 28.2743339 cm²
base surface area B = 28.2743339 cm²
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
total surface area A = 245.044227 cm²
total surface area A = 78 π cm²
Therefore the value of Surface Area of the cylinder is 245.04 cm².

Answers

Answer:
3. $6000 at 8%; $5000 at 5%
4. 66 2/3 gallons of 9%; 133 1/3 gallons of 6%
Step-by-step explanation:
For many mixture problems, it works well to let a variable represent the amount of the largest contributor used in the mix.
3. Let x represent the amount invested at 8%. Then the total interest is ...
8%x +5%(11000-x) = 730
3%x = 730 -550
x = 180/0.03 = 6000
$6000 was invested at 8%; $5000 was invested at 5%.
__
4. Let x represent the number of gallons of 9% content. Then the alcohol content of the mix is ...
9%x +6%(200 -x) = 7%(200)
3%x = 1%(200) . . . . . subtract 6%(200)
x = 200/3 = 66 2/3 . . . . . divide by 3%
200 -x = 133 1/3
66 2/3 gallons of 9% wine and 133 1/3 gallons of 6% wine should be used.
