The square pyramid below represents a tent that Wayne is making. The sides of the tent will be covered in blue fabric and the base of the tent will be covered in brown fabric. Find the surface area that will be covered in each color of fabric.
Answer:
The answer is below
Step-by-step explanation:
A square pyramid is a pyramid with a square base. Therefore it is composed of 4 identical triangles and a square base.
From the image attached:
Area of each of the triangle = (1/2) * 3 m * 4.5 m = 6.75 m²
Area of base = 3 m * 3 m = 9 m²
Since the sides are covered in blue fabric, hence:
Surface area of blue fabric = 4 * area of each triangle = 4 * 6.75 m² = 27 m²
The base is covered with brown fabric, hence Surface area of brown fabric = 4 * area of each triangle = 4 * 9 m² = 36 m²
simplify 3²×5² what is the answer

Brennan is wrapping a birthday present for his sister. He starts with 2 yards of ribbon. Then, he cuts off 9 inches to decorate the present. How many inches of ribbon does he have left now?
Answer:
63 inches
Step-by-step explanation:
Brennan is wrapping a birthday present for his sister. He starts with 2 yards of ribbon.
Step 1
We convert from yards to inches
1 yard = 36 inches
2 yards = x
Cross Multiply
x = 2 × 36 inches
x = 72 inches
Step 2
Then, he cuts off 9 inches to decorate the present.
The number of inches of ribbon he has left now is calculated as:
72 inches - 9 inches
= 63 inches
Therefore, he has 63 inches of ribbon left
how do I solve this?

Answer:
12 days, 72 tickets
Step-by-step explanation:
the x coordinate of the vertex (aka the number of days it takes to peak) is equal to -b/2a, where b is the coefficient of the second term and a is the coefficient of the first term. That is equal to -9.6/2*-0.4 = 12.
plug 12 in for x to get -0.4*12^2+9.6*12+14=71.6, which rounds to 72.
Hanako is putting up a fence around their rectangular yard. The fence will be 15 yards long and 6 yards wide. What is the area of Hanako's fence, in square yards?
Answer:
90 Square Yards
Step-by-step explanation:
To find the area of a rectangle, all you do is multiply the length by the width.
in your equation, the length is 15 and the width is 6.
And 15 x 6 = 90, so the answer is 90 Square Yards.

The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.Mathland skating rink charges $4.00 an hour to skate . what equation represents situation on;the skating palace
Answer:
Equation for the skating palace
= 6 + 2x
Step-by-step explanation:
Let the number of hours = x
For skating palace, the equation is written as:
The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.
$6 + $2 × x
= 6 + 2x
For Mathland , the equation is written as:
Mathland skating rink charges $4.00 an hour to skate .
$4 × x
= 4x
Therefore, the equation that represents the situation on the skating palace is :
6 + 2x

A pyramid and a cone are both 8 centimeters tall and have the same volume.
What statement must be true about the two solids?
АЛ
A. The vertical cross-sections of the prisms at the same width must
have the same area.
B. The area of the cross-sections of the prisms are multiples of each
other.
C. The cross-sections of the prisms are the same shape.
D. The horizontal cross-sections of the prisms at the same height
must have the same area.
Answer:
D. The horizontal cross-sections of the prisms at the same height must have the same area.
Step-by-step explanation: I dont know what the guy above is saying but this is the right answer
Since it is given that both prisms have the same height and volume, the answer is option D. The horizontal cross-sections of the prisms at the same height must have the same area.
A solid figure is one which has surface area and volume. Examples are prisms, cube, cuboid etc. Thus cones and pyramids are solid figures.
From the given question,
Volume of a cone, V = [tex]\frac{1}{3}[/tex][tex]\pi r^{2} h[/tex]
where r is its radius, and h its height
also,
Volume of a pyramid, V = [tex]\frac{1}{3}[/tex] lwh
where l is its length, w is the base width and h is its height.
Given that: i. volume of cone = volume of pyramid
ii. height of cone = height of pyramid
Then,
[tex]\frac{8}{3}[/tex][tex]\pi r^{2}[/tex] = [tex]\frac{8}{3}[/tex]lw
[tex]\pi r^{2}[/tex] = lw
Thus it can be deduced that at the same height, the horizontal cross section of the prisms have equal area. So that option D is the appropriate answer to the given question.

Determine the modulus of each of the complex numbers in the matching pairs. List these moduli in order from smallest to largest. Use the letters of the matching pair in your listing.
Suppose m = 2 + 6i, and |m + n| = 3√10 , where n is a complex number.
a. What is the minimum value of the modulus of n?
√10
Provide one example of the complex number, n.
A = J → 2 + 6i
B = F →75
C = H → -3 - i
D = I → 1 + i
E = G → 5 + 5i
these are my matching pairs
Answer:
the modulus of a complex number z = a + bi is:
Izl= √(a²+b²)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nl = 3√10
√(a² + b²+ 2²+ 6²)= 3√10
√(a^2 + b^2 + 40) = 3√10
squaring both side
a²+b²+40 = 3^2*10 = 9*10 =90
a²+b²= 90 - 40
a²+b²=50
So,
|n|=√(a^2 + b^2) = √50
The modulus of n must be equal to the square root of 50.
now
values a and b such
a^2 + b^2 = 50.
for example, a = 5 and b = 5
5²+5²=25+25= 50
Then a possible value for n is:
n = 5+5i
Let n be x+yi
So
√(a²+b²+2²+6²)=3√10√a²+b²+40=3√10a²+b²+40=90a²+b²=50Minimum value is 5+5i as 5²+5²=50

Geometry please help.
Answer:
CD = 16
Step-by-step explanation:
We can see that both AC and AB are radii. This means that they are equal, so AC = AB = 17. From segment addition postulate we can say AB = AE + BE
We are given BE, and we found the length of AB, so we can substitute and solve for AE:
AB = AE + BE
17 = AE + 2
AE = 15
Since we are given that AB is perpendicular to CD, ∠AEC would be a right angle, making ΔAEC a right triangle.
Now, we can use the pythagorean theorem to find the length of CE.
a^2 + b^2 = c^2
We are given the hypotenuse, c or AC in this case, and one leg, b, or AE in this case. We can plug in the values we are given:
CE^2 + AE^2 = AC^2
CE^2 + 15^2 = 17^2
CE^2 + 225 = 289
CE^2 = 64
CE = 8
Now, if a chord is perpendicular to a radius(AB in this case) we can say that it is split in half by the radius. This is basically saying that CE = DE = 8.
Again, using segment addition postulate, we can say:
CE + DE = CD
CD = 8 + 8
CD = 16

What is the radius, Diameter, Area, and Circumference of a 12 feet circle? (No links or fake answers, actually give me a right answer)
Answer:
12ft, 6ft, 36πft², 12πft
Step-by-step explanation:
Diameter: the distance across the circle - so 12ft
Radius: half the diameter = 0.5(12) = 6ft
Area: πr² = π(6)² = 36π ft² (substitute in 22/7, 3.14, or the exact value of π as fit)
Circumference: 2πr = πd = 12πft

What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Nancy and Fabian’s dinner bill at a restaurant is $28 before tax. The tax on their meal is 2.5%.
Let "T" be the final bill. Then the equation is given as,
2.5% = [(T - $28) / $28] x 100
0.025 = (T - $28) / $28
T - $28 = $0.70
T = $28.70
The amount that Nancy and Fabian’s final bill after tax is added will be $28.70.

Possible answers
= -1/2 + 1
= -2 +1
= 1/2 -1
= 2 -1
Given:
A line passes through the points (2,0) and (-2,2).
To find:
The equation of the line.
Solution:
If a line passes through the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (2,0) and (-2,2). So, the equation of the line is:
[tex]y-0=\dfrac{2-0}{-2-2}(x-2)[/tex]
[tex]y=\dfrac{2}{-4}(x-2)[/tex]
[tex]y=-\dfrac{1}{2}(x-2)[/tex]
[tex]y=-\dfrac{1}{2}(x)-\dfrac{1}{2}(-2)[/tex]
[tex]y=-\dfrac{1}{2}x+1[/tex]
Therefore, the required equation is [tex]y=-\dfrac{1}{2}x+1[/tex].
