13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
where & is the length (in yards) and w is the width (in yards).
a. Solve the formula for w.
P= 330 yd
b. Find the width of the field.
c. About what percent of the field
is inside the circle?
doc
10 yd
- 100 yd
Answer:
[tex]w = \frac{1}{2}(P - 24)[/tex]
[tex]w = 153\ yards[/tex]
Step-by-step explanation:
Given
[tex]P = 24 + 2w[/tex]
Require
Solving (a):
[tex]P = 24 + 2w[/tex]
Subtract 24 from both sides
[tex]P-24 = 24-24 + 2w[/tex]
[tex]P-24 = 2w[/tex]
Divide both sides by 2
[tex]\frac{1}{2}(P - 24) = \frac{2w}{2}[/tex]
[tex]\frac{1}{2}(P - 24) = w[/tex]
[tex]w = \frac{1}{2}(P - 24)[/tex]
Solving (b):
Substitute 330 for P un the expression in (1)
[tex]w = \frac{1}{2}(330 - 24)[/tex]
Evaluate the bracket
[tex]w = \frac{1}{2}(306)[/tex]
[tex]w = 153\ yards[/tex]

A child has a bottle full of pennies, nickels,dimes and quarters. There are twice as many quarters as pennies, four times as many nickels as pennies, and five times as many dimes as nickels. How many more dimes does the child have than quarters?
Answer:19x
Step-by-step explanation:
Take x as the value of pennies
If there are twice as many quarters as pennies then the explanation should be
Pennies =x
Quarters =2x
If there are 4 times as many nickels as pennies then the explanation is
Pennies =x
Nickels =4x
If there are 5 times as many dimes as nickels then the explanation is
Nickels =4x
Dimes=20x
So the values of them all is
Pennies =x
Nickels =4x
Dimes =20x
Quarters =2x
So to get how many more dimes does the child have than quarters you subtract
20x-2x=19x
The Number of dimes the child has more than quarters is; 10 times more.
Let number of pennies be P
Since he has twice as many quarters as pennies, then;
Number of quarters; Q = 2P
Four times as many nickels as pennies. Then;
Number of nickels; N = 4P
five times as many dimes as nickels. Then;
Number of dimes; D = 5N = 5(4P) = 20P
Since number of quarters = 2P
And number of dimes = 20P
Then;
Number of dimes the child has more than quarters is; 20P/2P = 10
Thus, the child has ten times as many dimes as quarters

It cost Brody $9.80 to send 196 text messages. How many text messages did he send if he spent $4.20? *
Answer:
84 text messages
Step-by-step explanation:
Set up a proportion and solve:
dollars / texts = dollars / texts
9.8 / 196 + 4.2 / x
9.8 * x = 4.2 * 196
9.8x = 823.2
9.8x / 9.8 = 823.2 / 9.8
x = 84
Brody would have sent 84 messages if he spent $4.20.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the cost of sending 196 text messages is $9.80.
Therefore,
$9.80 = 196 messages
$1 = 196/9.80 messages
$4.20 = (196/9.80)×4.20 messages
$4.20 = 84 messages
Hence, Brody would have sent 84 messages, if he spent $4.20.

The measue of the supplement of an angle 20° more than three times the measure of the original angle. Find the measures of the angles.
1. The sum of the measures of the two angles is:
Answer:
x = orgininal angle
3x +20 = supplementary angle
1. x + (3x+20) = 180
2. 4x + 20 = 180
3. 4x = 160
4. x = 40
The orginial angle is 40
The supplementary angle is 140
Step-by-step explanation:
1. define your varibles using the words given
2. add them together to equal 180, because they are supplmentary.
3. combine like terms.
4. subtract 20
5. divide by 4
6. you find x, now plug it back into your variables at the top:
x = 40

Obtain an expression that looks like this: 25+ 4 А B. X(S) = + s(s +6) S +6 S
A= ___________
B =____________
Answer:
[tex]A = \frac{2}{3}[/tex]
[tex]B = \frac{4}{3}[/tex]
Step-by-step explanation:
Given
[tex]X(s) = \frac{2s + 4}{s(s +6)}= \frac{A}{s} + \frac{B}{s + 6}[/tex]
Required
Find A and B
The expression can be rewritten as
[tex]\frac{2s + 4}{s(s +6)}= \frac{A}{s} + \frac{B}{s + 6}[/tex]
Take LCM of the right hand side
[tex]\frac{2s + 4}{s(s +6)}= \frac{A(s + 6 )+ Bs}{s(s +6)}[/tex]
Cancel out the denominators
[tex]2s + 4 = A(s + 6) + Bs[/tex]
Open Bracket
[tex]2s + 4 = As + 6A+Bs[/tex]
Reorder
[tex]2s + 4 = As +Bs+ 6A[/tex]
By direct comparison:
[tex]2s = As + Bs[/tex]
[tex]4 = 6A[/tex]
Solving [tex]2s = As + Bs[/tex]
Divide through by s
[tex]2 = A + B[/tex]
Solve for A in [tex]4 = 6A[/tex]
[tex]\frac{4}{6} = A[/tex]
[tex]A = \frac{4}{6}[/tex]
[tex]A = \frac{2}{3}[/tex]
Substitute [tex]\frac{2}{3}[/tex] for A in [tex]2 = A + B[/tex]
[tex]2 = \frac{2}{3} + B[/tex]
[tex]B = 2 - \frac{2}{3}[/tex]

Suppose a game show called Bayesian Boxes has the contestant sample one marble from a box and guess what type of box it is. When the contestant picks a box, the chance of each box type for this round is as follows: Type A: 75%, Type B: 20%, and Type C: 5% The chance of drawing a red marble from Type A is 2%, from Type B is 25%, and from Type C is 98%. The contestant selects a box and draws a marble. What is the chance of drawing a red m
Answer:
P(C/R) = 0.4298
Step-by-step explanation:
Missing word "arble, what is the chance it came from box Type C? (Give the decimal answer rounded to at least four places )"
Solution:
Given that P(A) = 75% = 0.75
P(B) = 20% = 0.20
P(C) = 0.05
The chance of drawing a Red marble fro,
P(R/A) = 2% = 0.02
P(R/B) = 25% = 0.25
P(R/C) = 98% = 0.98
If he select Box A than the probability of Red marble drawing
= P(A) * P(R/A)
= 0.75 * 0.02
= 0.015
If he select Box B than the probability of Red marble drawing
= P(B) * P(R/B)
= 0.20 * 0.25
= 0.5
If he select Box C than the probability of Red marble drawing
= P(C) * P(R/C)
= 0.98 * 0.05
= 0.049
So total probability of drawing Red marble is
P(R) = 0.015 + 0.050 + 0.049
P(R) = 0.114
If the Contestant draw a Red marble. Probability that it comes from box type (C) using Boyes theorem is
P(C/R) = {P(C) * P(R/C)} / P(R)
P(C/R) = 0.049 / 0.114
P(C/R) = 0.429824
P(C/R) = 0.4298

10 times as many as 1 hundred is _____ hundreds are _____thousands.
10 hundreds or 1 thousand.
Further explanation
This question is related to place values.
10 times as many as a number is 10 multiplies the number.
Hence, 10 times as many as 1 hundred is
\boxed{ \ 10 \times 1 \ hundred \rightarrow \boxed{ \ 10 \ hundreds \ } \ }
Furthermore, 10 hundreds have the same meaning as 1 multiplies 10 hundreds which can produce 1 thousand.
\boxed{ \ 1 \times 10 \ hundred \rightarrow \boxed{ \ 1 \ thousand \ } \ }
Quick steps
Part-1
\boxed{ \ 10 \times 1 \ hundred = X \ hundred \ }
\boxed{ \ 10 \ hundred = X \ hundred \ }
Thus, \boxed{\boxed{ \ X = 10 \ }}
Part-2
\boxed{ \ 10 \times 1 \ hundred = Y \ thousand \ }
\boxed{ \ 10 \times 100 = Y \ thousand \ }
\boxed{ \ 1,000 = Y \ thousand \ }
\boxed{ \ 1 \ thousand = Y \ thousand \ }
Thus, \boxed{\boxed{ \ Y = 1 \ }}

Answer:
[tex]x = 5 + \sqrt{35} \: \: \:or \: \: \: x = 5 - \sqrt{35} \\[/tex]Step-by-step explanation:
x² - 10x + 25 = 35
Move 35 to the left side of the equation
That's
x² - 10x + 25 - 35 = 0
x ² - 10x - 10 = 0
Using the quadratic formula solve the equation

Roman is considering buying shares of GHI stock. The stock currently sells for $60 per share. The stock changes in value at 8:00 am each day, either increasing in value by $10 or decreasing in value by $1. The stock will increase in value with 90% probability, and decrease in value with 10% probability. The stock follows a random walk. In three days, what is the probability that GHI is less than $70?
Answer:
The Probability that the GHI is less than $70 in three days is 1% or 0.01
Step-by-step explanation:
Here, we want to find the probability that the GHI is less than $70.
So what we do here is to find the scenarios that could make the $60 less than $70 is three days;
Scenario 1;
Two days decrease and one day increase
That will bring the value to 60 -1-1 + 10 = $68 which is less than 70
Scenario 2;
Three days decrease
That will bring the value to
60-1-1-1 = 57 which is less than 70
Any other possible scenario to make the value of the share less than 70? NO !
For the 1st case scenario;
Two days decrease and one day increase;
The scheduled probabilities will be as follows;
Kindly recall, probability of increase = 90% = 90/100 = 0.9
Probability of decrease = 10% = 10/100 = 0.1
So probability in scenario 1 will be;
P(Two days decrease and one day increase)
= 0.1 * 0.1 * 0.9 = 0.009
Kindly note this can happen in any order and since no order was specified, we do not need to consider other cases
Scenario ii
Three days decrease
That will be;
P(three days decrease) = 0.1 * 0.1 * 0.1 = 0.001
So the addition of both since we will be having either of the two and or means addition in probability will be ;
0.001 + 0.009 = 0.01 = 1%
