Answer:
I chose a box of cereal-------> rectangular prism
see the attached figure
Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length: 20 cm
Width: 8 cm
Height: 32 cm
Part 2).
Describe the shape of the cross-section when the box is cut parallel to the base
the shape of the cross-section would be a rectangle of dimensions
20 cm x 8 cm
Part 3)
What is the surface area of the box?
surface area=2*area of the base+perimeter of the base*height
area of the base=20*8=160 cm²
perimeter of the base=2*[20+8]-----> 56 cm
height=32 cm
surface area=2*160+56*32------> 2,112 cm²
the answer part 3) is
2,112 cm²
Part 4)
What is the surface area of the box if it is scaled up by a factor of 10?
we know that
surface area of the larger box=[scale factor]²*surface area original box
scale factor=10
surface area original box=2,112 cm²
so
surface area of the larger box=10²*2,112-----> 211,200 cm²
the answer part 4) is
211,200 cm²
Part 5)
What is the volume of the box?
volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³
the answer Part 5) is
5,120 cm³
Part 6)
What is the volume of the box if it is scaled down by a factor of 1/10
we know that
volume of the smaller box=[scale factor]³*volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³
the answer part 6) is
5.12 cm³

Find the value of y.
120°
Answer:
y = 60°
Step-by-step explanation:
The tangent- chord angle y is half the measure of its intercepted arc , then
y = [tex]\frac{1}{2}[/tex] × 120° = 60°
The value of y is 60 °
What is the tangent- chord angle theorem?"The angle generated by a tangent to a circle and a chord is equal to half the angle measure of the intercepted arc," is another way to state the Tangent-Chord theorem. Since the angle measure of an intercepted arc is double that of the inscribed angle that subtends it, this is equivalent to what we have demonstrated.The measure of an angle formed by a tangent and a chord meeting at the point of tangency is half the measure of the intercepted arc.Given , the angle is 120°
Now apply the tangent- chord angle theorem, " a chord meeting at the point of tangency is half the measure of the intercepted "
y = 1/2 × 120°
y = 1/2 × 120° = 60°
Therefore, the value of angle y is 60°.

The area of a trapezoid is 216 in2 and it two bases are 14 and 22 inches long. Find the height of the trapezoid.
Answer:
12 inches
Step-by-step explanation:
The formula for a trapezoid is
A = 1/2(a +b)h
The formula to find the height =
h = 2A/a + b
A= 216 in²
a =14 in
b = 22 in
Hence,
h = 2 × 216/14 + 22
h = 12 inches
The height of the trapezoid = 12 inches
Read the sentence. The baker donated bread to the fund-raiser in a large box. Which is the best revision of this sentence? In a large box, the baker donated bread to the fund-raiser. The baker donated to the fund-raiser bread in a large box. The baker donated a large box of bread to the fund-raiser. In a large box, the fund-raiser had bread donated by the baker.
Answer:
The prepositional phrase "of bread" establishes that the large box donated by the baker contains bread . Therefore, it is unnecessary to use the PP. So the baker donated a large box of bread tho the fundraiser.

can somebody find the volume of the cone on #2?
thank you!!
Answer:
[tex] 4,220.16 \: {units}^{3} [/tex]
Step-by-step explanation:
Diameter of cone = 24 units
Radius of cone (r) = 24/2 = 12 units
Height of cone (h) = 28 units
[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} [/tex]

Determine whether each equation represents a linear or a nonlinear function
Select Linear or Nonlinear for each equation
Step-by-step explanation:
Note:
Linear equations will never exponents in its equation such as
[tex] {x}^{2} \\ y = {x}^{3} [/tex]
as those equations will produce curly graphs.
Nonlinear equations will either contain exponents or logarithms (eg. ln2)

Angle ABC and angle CBD are complementary. What is the value of x? Record your answer as a whole number.
No links please please please.
Answer:
x=31
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
So, 2x+28=90.
To solve:
1. Subtract 28 from both sides
2x=90-28
2x=62
2. Divide both sides by 2
x=62/2
x=31
