Jake is wrapping a gift that is in a box with the following dimensions.
Length: 12 inches
Width: 4 inches
Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box. How many times larger is the surface area of Havana's box than Jake's box?
Answer:
Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:
SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)
SA = 2(84) + 2(48) + 2(112)
SA = 168 + 96 + 224
SA = 488 square inches of paper to wrap the box.

Explain at least 3 Properties of 0.
Answer:
Zero is even (not odd, not neutral)
Zero is neither positive nor negative (the only number with this property)
Zero is an integer (and must be considered when question limits choices to integers)
Zero is a multiple of all numbers (x*0 = 0, so a multiple of any x)
Step-by-step explanation:
Any number to the power of 0 is equal to 1. 0 is neither positive nor negative. 0 is neither prime nor composite. If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.

Answer:
x = 45
Step-by-step explanation:
The sum of the angles of a triangle is 180
80+55+x = 180
135 +x = 180
Subtract 135 from each side
x = 180-135
x =45
Answer:
45
Step-by-step explanation:
combining the a and b lengths gives you 135 then subtract by 180 and you get 45.
Find the area of the shaded region:
Find the area of the circle:
Area = PI x r^2
Area = 3.14 x 9^2
Area = 3.14 x 81
Area = 254.34 square cm
Now multiply the area of the circle by the shaded portion which is the fraction of the degree over 360 degrees:
254.34 x 80/360 = 20,347.2/360 = 56.52
The shaded area is 56.52 square cm.
Area of circle formula: A = πr²
A = π(9)²
A = 81π
A = 254.34cm²
The ratio of degrees in the shaded region to total degrees in a circle:
80/360 = 40/180 = 20/90 = 10/45 = 2/9
Multiply:
254.34/1 * 2/9
508.68/9
56.52
Therefore, the area of the shaded region is 56.52cm²

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation:
y = x squared + 7 x
Answer:
a=1, b= 7, c=0
Opens upward since a is positive(meaning it has a minimum vertex)
Y-int: (0,0)
Step-by-step explanation:
y=[tex]x^{2}[/tex]+7x
In order to find, the y-intercept, x has to be 0, so plug in 0 for x
y=[tex]0^{2}[/tex]+7(0)
y=0
So the y intercept: (0,0)
The equation form a parabola that opens up and the y intercept is at y = 0. a = 1, b = 7 and c = 0
What is a quadratic function?A quadratic function is in the form:
y = ax² + bx + c

Answer:
Look at the figure and take note of the types of three-dimensional figures that make it up. Find the volume of each figure. Add the volumes to find the total volume.
Step-by-step explanation:
The volume of the composite figure is solved
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
If a composite figure is made up of a rectangular prism and a triangular prism, you can find the volume of the rectangular prism by multiplying its length, width, and height. Then, you can find the volume of the triangular prism by multiplying its base, height, and 1/2. Finally, you can add the volumes of both prisms to get the total volume of the composite figure.
Similarly, if a composite figure is made up of two rectangular prisms, you can find the volume of each prism by multiplying its length, width, and height. Then, you can add the volumes of both prisms to get the total volume of the composite figure.

Shani sells televisions. The formula she uses to calculate her monthly income is A = 800 + 200t, where A equals her total monthly income
and equals the number of televisions she sells.
How much money did Shani earn if she sold 9 televisions?
А S800.00
в, $1,000,00
с. $1,800.00
D, $2,600,00
Е. $9,000.00
Answer:
D
Step-by-step explanation:
plug in 9 where ‘t’ is. the formula becomes
A= 800+ 200(9) multiply 9 x 200
A= 800 + 1,800 add
A= 2,600
Answer:
D
Step-by-step explanation:
800 is the base amount she is already given/has. Since it is 200t the t represents how many televisions she sells so by doing 800 + 200(9) you will get 2,600.00.

Answer:
I am pretty sure it is D.
Step-by-step explanation:

The top of the gumball machine on the left is a sphere with a diameter of 20 inches. When the machine is full it can hold 3500 gumballs, leaving 40% of the space in the machine empty. What is the approximate radius of each gumball? Round to the nearest hundredth and use 3.14 for Pi
Answer:
0.555 in
Step-by-step explanation:
The first thing we must do is calculate the volume of the machine, the volume of a wait is:
v = (4/3) * pi * (r ^ 3)
we know that the diameter is twice the radius, therefore:
r = d / 2 = 20/2
r = 10, replacing:
v = (4/3) * 3.14 * (10 ^ 3)
v = 4186.66 in ^ 3
Now, we know that by leaving 40% of space in the machine there are 3,500 chewing gums, therefore, 60% of that volume is chewing gum.
4186.66 * 0.6 = 2512
to calculate the volume of a chewing gum:
3500 * v = 2512
v = 2512/3500
v = 0.7177 in ^ 2 is the volume of a single chewing gum
if we solve the sphere formula for r, we are left with:
r ^ 3 = v * (3/4) / pi
replacing
r ^ 3 = 0.7177 * (3/4) /3.14
r ^ 3 = 0.1714
r = 0.1714 ^ (1/3)
r = 0.555
the radius of each gum is 0.555 in

Please help thx
First, find the total distance between A and B.
3 + 21 = 24 units
Second, divide by 8.
24 / 8 = 3
Third, multiply by 3.
3 * 3 = 9
Therefore, the answer is 3.
Best of Luck!
Answer:
D 6
Step-by-step explanation:
First, we find the distance between points A and B.
AB = |a - b| = |-3 - 21| = |-24| = 24
The distance from A to B is 24.
Now we need 3/8 of that distance.
3/8 of 24 = 3/8 * 24 = 3/8 * 24/1 = 72/8 = 9
Point Q is 9 units to the right of point A.
-3 + 9 = 6
