4. Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Vietnamese conical hats in baby prints tissue paper to decorate the tables and some
shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If
she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
A 4,176 in2
B 8,975 in2
C 10,580 in2
D 36,267 in 2
Answer:
Step-by-step explanation:
Given the information of the conical hat
diameter of 16 inches => Radius = 8 inches height of 9 inches=> the slant height of the hat is (use Pythagorean Theorem)
[tex]s^{2}[/tex] = [tex]r^{2} + h^{2}[/tex]
<=> [tex]s^{2}[/tex] = [tex]8^{2} + 9^{2}[/tex]
<=> s = [tex]\sqrt{145}[/tex]
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8*[tex]\sqrt{145}[/tex] in2
<=> SA =8 [tex]\sqrt{145}[/tex] π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8 [tex]\sqrt{145}[/tex] π*21
= 6352,18 in 2

After reaching the summit, she descends 14 feet in 213 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?
Complete Question
Maggie is rock climbing. After reaching the summit, she descends 14 feet in 213 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?
Answer:
Maggie will be [tex]x = 0.53 \ feet[/tex] from the previous position
Step-by-step explanation:
From the question we are told that
The distance of descent is [tex]d = 14 ft[/tex]
The time taken is [tex]t = 213 \ minutes[/tex]
So she descended 14ft in 213 minutes
So she would descend x ft in 8 minutes
Hence
[tex]x = \frac{14 * 8 }{213}[/tex]
[tex]x = 0.53 \ feet[/tex]

What is \text{P(not }3)P(not 3)start text, P, left parenthesis, n, o, t, space, end text, 3, right parenthesis? If necessary, round your answer to 222 decimal places.
Answer:
There is no enough information to determine probability of not having 3, P(not 3).
Suppose we were given the probability of having 3, P(3), we can easily find P(not 3).
The probability of success plus the probability of failure of an event is always equal to 1.
If p is the probation success, and q, of failure, then p + q = 1
So,
P(3) + P(not 3) = 1
That is
P(not 3) = 1 - P(3).
Hi please can any one help me please
Answer:
I will explain how to do this.
Step-by-step explanation: For example A-B is going away from her home because the distance is changing and in the beginning it says Mary starts at her house. So now to continue, where the first letter meets the last letter ( in this scenario its A-B) you'll look at the space between it and count the ticks on the side where it says distance and use the number on the side to guide you. Now for time you'll do the same thing with the ticks on the side. But for where it goes down she is going the opposite way so it'll still be distance but she will be going back home, for the straight line that means she is not moving at all. Hope this helps :)
The students are doing a fundraiser to help out a friend. They are selling chocolate and cookies for $3 and $2.50 respectively. The cookies were presold to 60 people. At least how many of the chocolates must be sold to collect $255?
Answer:
At least 18 chocolates sold to collect $225
Step-by-step explanation:
~ Let's say x ⇒ the number of chocolates, y ⇒ the number of cookies ~
1. We can see that the number of chocolates/ cookies * the cost of chocolates/cookies = the total cost of chocolates/cookies. Provided this, it would be that 3x and 2.5y would represent the cost of chocolates and cookies.
2. It is given that there was $225 sold from chocolates and cookies, so we can say that 3x + 2.5y = 225 from this assumption.
3. That being said it is also known that the cookies were sold to 60 people, so we can assume that 60 cookies were sold out, 1 were person. With this information we can see that 3x ⇒ 3 * 60 = 180 ⇒ cost of cookies sold
4. Now we can substitute this value of 3x into the equation 3x + 2.5y = 225, as such: 3x + 2.5y = 225 ⇒ 180 + 2.5y = 225, and now we can solve for y ~
180 + 2.5y = 225,
2.5y = 225 - 180,
2.5y = 45,
y = 45/2.5,
y = At least 18 chocolates sold to collect $225

a block of wood is a cube and has the dimensions 5cm by 5cm by 5 cm what is the volume of the block of wood
Answer: 125 cubic cm
A block's volume is found by multiplying the length, width and height. We have 5*5*5 = 125 as the volume. The units are in cubic centimeters which you can write as "cubic cm" or "cc" for short. Another way to write it is as "cm^3"
Side note: Your math book or your teacher may refer to a block as a rectangular prism.
Answer:
125cm^3
Step-by-step explanation:
the formula for V of a cube is length x width x height. so you will go 5cm x 5cm x 5cm =125cm^3

y = -9x - 14
x-intercept
y-intercept:
Answer: The x intercept is (-14/9,0) which means the x intercept is -14/9. The y intercept is -14.
Step-by-step explanation:
the x intercept is when y is 0 so using the equation we could solve for x by putting in 0 for y.
0=--9x - 14
+ 14 +14
14= -9x
x= -14/9
The y intercept is when x is zero so using the same method we will put in 0 for x in the equation and solve for y.
y= -9(0) - 14
y= 0-14
y= -14

Answer:
[tex]\left|\begin{array}{c|c|c|c|c||c}$Country Visited&$UK& $France& $Spain& $Italy &$Total\\&&&&&\\$Number of Customers &968& 248& 2042& 742& 4000\\&&&&&\\$Number of sample&121&31&255&93&500\end{array}\right|[/tex]
Step-by-step explanation:

Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.
For UK, Number of Samples[tex]=\dfrac{968}{4000}X500=121[/tex]
For France, Number of Samples[tex]=\dfrac{248}{4000}X500=31[/tex]

Step-by-step explanation:
Imagine the ratio is a fraction: 2/4. Simplify the ratio the same way you'd simplify the fraction. Both the numerator and the denominator are divisible by 2. Divide both by two, and you get 1/2.
Therefore, the simplest ratio is 1 to 2.
Two beach rental companies compared their sales from last weekend. Both companies rent out jet skis and kayaks, and they charge the same prices. Will's Watersports made a total of $780 from renting 12 jet skis and 9 kayaks. Family Fun Rentals made a total of $570 from renting 7 jet skis and 11 kayaks. What is the cost of each type of rental?
Answer:
To rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20
Step-by-step explanation:
Since both shops charge the same amount for each kind of vehicle, we will assign variables to the their cost. The cost of a jet ski will be "x" and the cost of the kayak will be "y". Therefore we can create a system of equations as shown below:
Will's shop:
12*x + 9*y = 780
Fun Rentals:
7*x + 11*y = 570
[tex]\left \{ {{12x+ 9y=780} \atop {7x + 11y =570}} \right.\\[/tex]
We can isolate "x" on the second equation, we have:
[tex]x = \frac{570 - 11y}{7}[/tex]
Applying this value on the first equation:
[tex]12[\frac{570 - 11y}{7}] + 9y = 780\\\frac{6840 - 132y}{7} + 9y = 780\\\frac{6840 - 132y + 63y}{7} = 780\\ 6840 - 132y + 63y = 5460\\6840 - 69y = 5460\\69y = 1380\\y = 20[/tex]
Applying the value of "y" we found on the "x" equation above, we have:[tex]x = \frac{570 - 11*20}{7}\\x = 50\\[/tex]
Therefore to rent a jet ski you need to pay $50 and to rent a kayak you need to pay $20

i solved it using the furmola :
[tex]2\pi \times r \frac{45}{360} [/tex]
Answer:
a = 1.57 inStep-by-step explanation:
We know that the length of the arc in a circle is proportional to its corresponding angle which means:
a corresponds to 45
2πr corresponds to 360
then
[tex]\frac{a}{45} = \frac{2\pi r}{360}[/tex]
then
a = (45÷360)×4×π

Identify the center and radius of each. Photo attached.
Answer:
Center ~ ( -4, 3 ), Radius ~ 2; Option A
Step-by-step explanation:
~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2 provided r ⇒ radius of the circle, centered at ( a, b ) ~
1. If we are given the circle formula ( x + 4 )^2 + ( y - 3 )^2 = 4, it would be that the center points ( a, b ) would be the inverse of 4 and -3, provided the formula is -a and -b: center ( -4, 3 )
2. Now the radius in the formula ( x - a )^2 + ( y - b )^2 = r^2, is noted by r such that in ( x + 4 )^2 + ( y - 3 )^2 = 4, r^2 is 4 ⇒ r = √4 = 2
3. We now know that the center of this circle is ( -4, 3 ) with a radius of 2, and the only graph that represents that function is the first graph ~
Answer: Center ~ ( -4, 3 ), Radius ~ 2
