What is the area of the trapezoid? The diagram is not drawn to scale.
A. 36 cm2
B. 9 cm2
C. 21 cm2
D. 16.5 cm2
Answer:
Area of trapezoid = 21 cm²
Step-by-step explanation:
Given:
Length of rectangular shape = 4 cm
Width of rectangular shape = 3 cm
Base of triangle = 3 cm
Number of triangle = 3 cm
Find:
Area of trapezoid
Computation:
Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]
Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]
Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]
Area of trapezoid = 12 + 9
Area of trapezoid = 21 cm²

4 A roll of paper is shown below.
Tube
About how much cardboard is needed to make the inner tube for a roll of paper if the tube
has a diameter of 4.5 cm and is 24 cm long?
F 339 cm2
G 679 cm2
H 371 cm2
J
382 cm2
Answer:
339 cm²
Step-by-step explanation:
Using the relation for the surface area of a cylinder :
A = 2πrh
r = Radius = diameter / 2 = 4.5 / 2 = 2.25 cm
Height, h = 24 cm
A = 2 * 22/7 * 2.25 * 24
A = 339.29200 cm²
Surface Area =339 cm²
About 339cm³ of cardboard will be needed for the inner tube.
To make inner tube card board needed is 339 cm² of the material.
What is Surface area ?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Here, diameter = 4.5 cm
then, radius = 4.5/2 = 2.25 cm
height = 24 cm
Surface area = 2πrh
= 2 X 3.14 X 2.25 X 24
= 339.12 cm²
Thus, to make inner tube card board needed is 339 cm² of the material.

Can someone tell me the answers wit shown work or something
Step-by-step explanation:
1) solution
Hypotenous(h)=?
perpendicular(p)=16
base(b)=12
By using formula
h^2 = p^2 + b^2
h^2 = 16^2 + 12^2
h^2 = 256 + 144
h^2 = 400
h^2 = 20^2
h = 20
therefore hypotenous (h) is 20
2) solution
hypotenous = (?)
perpendicular=(77)
base=(36)
by using formula
h^2 =p^2 + b^2
h^2=77^2+ 36^2
h^2=5929+1296
h^2=7225
h^2=85^2
h=85
therefore hypotenous (h) is 85

Answer:
3 adult tickets and 5 children tickets.
Step-by-step explanation:
Make a chart:
1 adult + 7 children = 1(5)+7(3) = 26
2 adults + 6 children = 2(5)+6(3) = 28
3 adults + 5 children = 3(5)+5(3) = 30
4 adults + 4 children = 4(5)+4(3) = 32
5 adults + 3 children = 5(5)+3(3) = 34
6 adults + 2 children = 6(5)+2(3) = 36
7 adults + 1 child = 7(5)+1(3) = 38
The answer in bold is the only one that leads to $30, therefore he bought 3 adult tickets and 5 children tickets.

Answer:
answer: x = 55
Step-by-step explanation:
Because a triangle will add up to 180 degrees 2 of are angles are given so I will subtract them from 180 for answer so 27 + 98 = 125
180 - 125 = 55 Hope this helps!
Answer:
x = 55°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° for x
x = 180° - (98 + 27)° = 180° - 125° = 55°

What is the probability of getting a heads on a coin and then getting a 5 on a number cube?
Answer:
In probability theory, sample space (also called sample description space[1] or possibility space[2]) of an experiment or random trial is the set of all possible outcomes or results of that experiment.[3] A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S, Ω, or U (for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.[4]
For example, if the experiment is tossing a coin, the sample space is typically the set {head, tail}, commonly written {H, T}.[5] For tossing two coins, the corresponding sample space would be {(head,head), (head,tail), (tail,head), (tail,tail)}, commonly written {HH, HT, TH, TT}.[6] If the sample space is unordered, it becomes {{head,head}, {head,tail}, {tail,tail}}.
For tossing a single six-sided die, the typical sample space is {1, 2, 3, 4, 5, 6} (in which the result of interest is the number of pips facing up).[7]
A subset of the sample space is an event, denoted by E. Referring to the experiment of tossing the coin, the possible events include E={H} and E={T}.[6]
A well-defined sample space is one of three basic elements in a probabilistic model (a probability space); the other two are a well-defined set of possible events (a sigma-algebra) and a probability assigned to each event (a probability measure function).
Another way to look at a sample space is visually. The sample space is typically represented by a rectangle, and the outcomes of the sample space denoted by points within the rectangle. The events are represented by ovals, and the points enclosed within the oval make up the event.[8]

At your local store, you are given a coupon for 20% off any store item purchased on Monday. When you return to your store, you notice that an item (normal price = $50) is on clearance for 40% off. You are allowed to use the coupon on the clearance item. How much should you pay for the item? Should it be 60% off of the normal price?
Answer:
$24
no, it is 48% off normal price
Step-by-step explanation:
clearance price = normal price - value of the 40% discount
value of the 40% discount = 0.4 x $50 = $20
Price = $50 - $20 = $30
final price = clearance price - value of 20% coupon
value of 20% coupon = 0.2 x $30 = $6
final price = $30 = $6 = $24
total value off normal price = $24 /$50 x 100 = 48%

Answer:
1193.2 sq. in.
Step-by-step explanation:
SA = LA + 2B
where LA is the lateral area and B is the area of the base (circle)
B = πr^2 = 3.14(10)^2 = 3.14(100) = 314
Area of 2 Bases = 2 (314) = 628
LA = Ch where C is the circumference of the base
LA = πdh = 3.14(20)(9) = 565.2

Answer:
54
Step-by-step explanation:
3*6*3=54
The solution is Option G.
The number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is given by combination C = 54 ways
What are Combinations?The number of ways of selecting r objects from n unlike objects is:
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt be C
Now , the equation will be
The total number of shoes = 3 pairs
The total number of pants = 3 pairs
The total number of shirts = 6 shirts
And , the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is calculated by Combination , where
The number of ways of selecting 1 pair of shoes = ³C₁
The number of ways of selecting 1 pair of pants = ³C₁
The number of ways of selecting 1 shirt = ⁶C₁
So , the total number of ways = ³C₁ x ³C₁ x ⁶C₁
On simplifying the equation , we get
The total number of ways C = 3 x 3 x 6
The total number of ways C = 54 ways
Hence , the combination is C = 54 ways

HOW TO DO THIS QUESTION
Answer:
A ≈ 40.3 cm²
Step-by-step explanation:
The area of right Δ ACD is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here A = 50.5, b = CD and h = AC , then
[tex]\frac{1}{2}[/tex] × 14 × AC = 50.5
7 AC = 50.5 ( divide both sides by 7 )
AC ≈ 7.214
The area of Δ ABC is calculated as
A = [tex]\frac{1}{2}[/tex] × BC × AC × sin36°
= 0.5 × 19 × 7.214 × sin36°
≈ 40.3 cm² ( to 3 sf )
9514 1404 393
Answer:
64.2 cm²
Step-by-step explanation:
The length AC is found from ...
Area of ACD = (1/2)(AC)(CD)
80.5 cm² = (1/2)(AC)(14 cm)
AC = 80.5 cm²/(7 cm) ≈ 11.5 cm
__
The area of ∆ABC is ...
Area ABC = (1/2)(CB)(CA)sin(C)
= (1/2)(19 cm)(11.5 cm)sin(36°) ≈ 64.2 cm²

Given that,
The radius of the sphere, r = 8 mm
We need to find the volume of the sphere. The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
Put all the values,
[tex]V=\dfrac{4}{3}\times 3.14\times 8^3\\\\=2143.57\ mm^3[/tex]

Can I have the slope and y intercept for 2y - 4x - 10 =0
Answer:
Slope = 2, Y-intercept = (0, 5)
Step-by-step explanation:
First, isolate y by moving all other terms to the other side of the equation.
2y - 4x - 10 = 0 ⇒ 2y = 4x + 10 ⇒ y = 2x + 5
The coefficient next to the x tells you the slope and the constant on the end tells you the y-intercept.
Therefore, the slope is 2 and the y-intercept is (0, 5).
Answer:
slope=2 ,y-intercept=5
Step-by-step explanation:
2y-4x-10=0
2y=4x+10+0
2y=4x+10 . divide both sides by 2
y=2x+5

Which line is perpendicular to 4y+3x=12?
A)3x+4y=8
B)y=-3x+8
C)y+4x=-3
D)8x-6y=18
Answer:
D) 8x - 6y = 18
Step-by-step explanation:
The general equation of a line is;
y = mx + c
m is the slope and c is the y-intercept
so for;
4y + 3x = 12
4y = -3x + 12
divide through by 4
y = -3/4x + 3
the slope here is -3/4
To get the other line, we divide -1 by the slope of the first line
This is because when two lines are perpendicular, the product of their slopes is -1
So the slope of the line we are looking for is -1 divide by -3/4 = 4/3
Let us take a look at option D
8x - 6y = 18
6y = 8x - 18
divide through by 2
3y = 4x - 9
divide through by 3
y = 4/3(x) - 3
So as we can see, we have our slope as 4/3 and this option is our answer
