Jordan prepares 200 name tags to use at a meeting. The number for each color of the name tag is described below.
35%of the name tags are blue
3/8 of the name tags are yellow
*all of the remaining name tags are red
how many of Jordans name tags are red ?
A)55
B)90
C)110
D)145
please help thxs!! due today 11:00 pm
Answer:
The answer would be A. 55.
Step-by-step explanation:
For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.
For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
The number of Jordan's tags that are red are; A: 55 tags
How to calculate proportions?35% of the 200 tags are blue. Thus;
Number of blue tags = 35% * 200 = 70 tags
3/8 of the 200 name tags are yellow. Thus;
Number of yellow tags = 3/8 * 200 = 75 tags
The remaining tags are red. Thus;
Number of red tags = 200 - (75 + 70)
Number of red tags = 55 tags

What is the sum of the interior angles in the polygon below? Show and explain your work.
Answer:
HEXAGON:
Using the same methods as for hexagons to the right (I'll let you do the pictures)...
To find the sum of the interior angles of a dodecagon, divide it up into triangles... There are ten triangles... Because the sum of the angles of each triangle is 180 degrees... We get
So, the sum of the interior angles of a dodecagon is 1800 degrees.
Regular Dodecagons:The properties of regular dodecagons:
All sides are the same length (congruent) and all interior angles are the same size (congruent).
To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)... And there are twelve angles...
So, the measure of the interior angle of a regular dodecagon is 150 degrees.
The measure of the central angles of a regular dodecagon:
To find the measure of the central angle of a regular dodecagon, make a circle in the middle (I'll let you do the picture)... A circle is 360 degrees around... Divide that by twelve angles...
So, the measure of the central angle of a regular dodecagon is 30 degrees.
A set of wrist watch prices are normally distributed with a mean of 767676 dollars and a standard deviation of 101010 dollars. What proportion of wrist watch prices are between 636363 dollars and 909090 dollars? You may round your answer to four decimal places. S
Answer:
0.8224
Step-by-step explanation:
Data
mean: $76standard deviation, sd: $10first value of interest, x1: $63second value of interest, x2: $90z-score for x1:
z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3
z-score for x2:
z2 = (x2 - mean)/sd = (90 - 76)/10 = 1.4
The proportion of wrist watch prices are between $63 and $90 is:
P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)
P(z < 1.4) = 0.9192 (see first picture attached)
P(z < -1.3) = 0.0968 (see second picture attached)
P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224

from least to greatest:
6/5, 0.3815, 97%
Answer:
6/5, 0.3815, 97%
Step-by-step explanation:
6/5 = 1.2 = 12%
0.3815 * 100 = 38.15%
97%
Answer:
.3815, 97%, 6/5
Step-by-step explanation:
To keep this simple, just convert all of them into decimals. 6/5= 1.2 if you divide it. 97%= 0.97 because you divide the percent by 100 to get to the decimal. And finally, .3815 is already a decimal.
Now, you just sort it out. 1.2 is the largest number because it is the only one that is greater than 1. So that would go last
Now you compare .97 and .3815. To find out which one is greater, look in the tenths place, or the first digit after the decimal. 9 is obviously greater than 3 so .97 is greater than .3815.
Using this info we found, the smallest is .3815, then 97%, then 6/5

The sector has an area of 3 pi inches squared and a radius of 6 in. How many inches long is the arc for this sector? Use 3.14 for Pi and round to the nearest hundredth.
A sector with a radius of 6 inches and area of 3 pi inches squared.
Recall that Area of a sector = StartFraction n degrees over 360 degrees EndFraction (pi) (r squared) and StartFraction Arc length over Circumference EndFraction = StartFraction n degrees over 360 degrees EndFraction.
3.14
6.28
12.56
18.84
Answer: 6.28 inches.
Step-by-step explanation:
Formula :
i) Area of sector : [tex]A=\dfrac{x}{360}\times\pi r^2,[/tex], where x = central angle and r is radius
ii) Length of arc : [tex]l=\dfrac{x}{360}\times2\pi r[/tex]
Given , r= 6 in.
A = [tex]3\pi[/tex] inches
Put these values in (i) , we get
[tex]3\pi =\dfrac{x}{360}\times\pi (3)^2\\\\\Rightarrow\ 1=\dfrac{x}{120}\\\\\Rightarrow\ x=120^{\circ}[/tex]
Now , put values of x and r in (ii) , we get
[tex]l=\dfrac{120}{360}\times2\pi(3)\\\\\Rightarrow\ l=2\pi = 2(3.14)=6.28\text{ inches}[/tex]
Hence, the length of the arc is 6.28 inches.

The first two terms of an arithmetic sequence are a1 = 2 and a2 = 5. Find a6, the
sixth term of the sequence.
OA) 27
B) 20

Answer:
D. 17.
Step-by-step explanation:
The nth term of an arithmetic sequence (an) is a1 + d(n - 1) where a1 = first term and d = the common difference.
In this sequence d = a2 - a1 = 5 - 2 = 3.
a6 = 2 + 3(6 - 1)
= 2 + 3*5

Step-by-step explanation:
Given: coordinate grid
To find: the missing number
Solution:
Equation of the parabola that open downwards and is symmetric about y-axis is [tex](x-h)^2=-4p(y-k)[/tex] where [tex](h,k)[/tex] denotes the vertex and focus is at [tex](h,k+p)[/tex]
[tex]g(x)=-(x-.....\,\,\,\,)^2+\left ( ....... \right )\\(x-.....\,\,\,\,)^2=-\left ( g(x)-(....) \right )[/tex]
[tex](x-h)^2=-\left ( g(x)-(k) \right )[/tex]
From the graph, vertex is [tex](5,4)[/tex]. Put [tex](h,k)=(5,4)[/tex]
[tex]g(x)=-(x-5)^2+4\\=-\left [ (x-5)^2-2^2 \right ][/tex]
Use formula [tex]a^2-b^2=(a+b)(a-b)[/tex]
So,
[tex]g(x)=-\left [ (x-5)^2-2^2 \right ]\\=-\left [ (x-5-2)(x-5+2) \right ]\\=-(x-7)(x-3)[/tex]

Describe how to optimize a function given a set of constraints.
The setup for this problem is written as l(x,y)= f(x,y)+λg(x,y)
For example, a common economic problem is the consumer choice decision. Households are selecting consumption of various goods. However, consumers are not allowed to spend more than their income (otherwise they would buy infinite amounts of everything!!). Let’s set up the consumer’s problem:
Suppose that consumers are choosing between Apples (A) and Bananas (B). We have a utility function that describes levels of utility for every combination of Apples and Bananas.
11
A 2 B 2 = Well being from consuming (A) Apples and (B) Bananas.
Next, we need a set of prices. Suppose that Apples cost $4 apiece and Bananas cost $2 apiece. Further, assume that this consumer has $120 available to spend. The income constraint is
$2B+$4A≤$120
However, the problem requires that the constraint is in the form g(x, y)≥ 0. In
the above expression, subtract $2B and $4A from both sides. Now we have 0≤$120−$2B−$4A
g(A, B) Now, we can write out the lagrangian
11
l(A,B)= A2 B2 +λ(120−2B−4A)
f (A, B) g(A, B)
Step II: Take the partial derivative with respect to each variable We have a function of two variables that we wish to maximize.
Therefore, there will be two first-order conditions (two partial derivatives that are set equal to zero).

Which linear equation has no solution? 23(9x+6)=6x+4 5x+12=5x−7 4x+7=3x+7 −3(2x−5)=15−6x
Answer:
5x+12=5x-7
Step-by-step explanation:
If both x's on each are the same number, but with different constants, then the equation is unsolvable. If 5x+12=y, then 5x-7 can't also equal y because they are two different equations.
With all other equations, although some come out irrational, they are solvable and have a solution to them.

Answer:
The answer is 324π m².
Step-by-step explanation:
Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius :
[tex]radius = diameter \div 2[/tex]
[tex]radius = 18 \div 2[/tex]
[tex]radius = 9m[/tex]
Then substitute into the formula :
[tex]s.a = 4 \times \pi \times {r}^{2} [/tex]
[tex]let \: r = 9[/tex]
[tex]s.a = 4 \times \pi \times {9}^{2} [/tex]
[tex]s.a = 4 \times \pi \times 81[/tex]
