Marge wants to build a sidewalk of uniform width around a rectangular swimming pool that is 80 feet long and 50 feet wide.she has 2000 square feet of concrete to create the sidewalk.what should be the width of the sidewalk
Answers
We have then:
(80 + 2W) (50 + 2W) - 80 (50) = 2,000
Rewriting we have:
4000 + 160W + 100W + 4W ^ 2 - 4000 = 2000
4W ^ 2 + 260W - 2000 = 0
W1 = 6.949334595148748
W2 = -71.94933459514874 (ignore)

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle B?
Enter your answer in the box.
m∠B=
°
Answers
7x° = 180°-19°
7x° = 161°
x = 23°
m∠B = 6(23) + 19
= 157°
Answer:
∠B=157°
Step-by-step explanation:
It is given that Quadrilateral ABCD is inscribed in the circle.
Also, we know that if the Quadrilateral ABCD is inscribed in the circle, then the opposite angles of the quadrilateral are supplementary by the property of circles. Then,
∠B+∠D=180°
⇒[tex]x+6x+19=180[/tex]
⇒[tex]7x+19=180[/tex]
⇒[tex]7x=161[/tex]
⇒[tex]x=23^{{\circ}}[/tex]
Thus, the value of ∠B=6x+19=6(23)+19=138+19=157°.
Cary is 5 5 years older than dan. in 5 years the sum of their ages will be 81. find the age of each man now.
Answers
C - 55 = D
(C + 5) + (D + 5) = 81
C = D + 55
(D + 55 + 5) + (D + 5) = 81
(D + 60) + (D + 5) = 81
2D = 16
D = 8
C = 8 + 55 = 63
Cary is 63 years old, and Dan is 8 years old
y = x - 55
x + 5 + y + 5 = 81
Then,
x + 5 + x - 55 + 5 = 81
2x - 45 = 81
2x = 81 + 45
2x = 126
x = 126/2 = 63
Now, let's find y.
y = 63 - 55 = 8.
Therefore Cary is 63 years old and Dan is 8 years old.

The hours of daylight,y, in Utica in days, x, from January 1, 2013 can be modeled by the equation y=3.06sin(0.017x-1.40) + 12.23. How many hours of daylight, to the nearest tenth,does this model predict for February 14, 2013?
(1) 9.4
(2) 10.4
(3)12.1
(4)12.2
Answers
Answer:
Option (4) 12.2
Step-by-step explanation:
Hours of daylight, y, in Utica in days, x, from January 1, 2013 can be modeled by the equation
y = 3.06 sin ( 0.017x - 1.40 ) + 12.23
We have to calculate the hours of daylight from the given equation for February 14, 2013.
From January 1, 2013 to February 14, 2013 number of days = 31 + 14 = 45 days.
Now we place x = 45 days in the equation
y = 3.06 sin (0.017 × 45 - 1.40) + 12.23
= 3.06 sin ( 0.765 - 1.40 ) + 12.23
= 3.06 sin ( - 0.635 ) + 12.23
= 3.06 ( - 0.0111) + 12.23
= -0.0339 + 12.23 = 12.196 = 12.20
Option (4) 12.2 is the correct answer.
The number of hours of daylight for the model for February 14 , 2013 is 12.2
Given data:
The function is represented as y=3.06sin(0.017x-1.40) + 12.23
To find the number of hours of daylight predicted by the model for February 14, 2013, substitute the corresponding value of x into the equation and evaluate it.
The total number of days , x = 31 days in January + 14 days in February
So, x = 45
Now, substitute x = 45 into the equation:
y = 3.06sin(0.017(45) - 1.40) + 12.23
Calculating the expression inside the sine function:
0.017(45) - 1.40 = -0.635
Substituting this value back into the equation:
y = 3.06sin(-0.635) + 12.23
The sine of -0.635 is approximately -0.593.
y = 3.06(-0.593) + 12.23
y ≈ 10.425
Rounding to the nearest tenth, the predicted number of hours of daylight for February 14, 2013, is 10.4.

Use the three steps to solve the problem. Betty has 10 more dimes than quarters. If she has $3.45, how many coins does she have?
Answers
Let
x-----------> number of dimes
y-----------> number of quarters
Step 2: set the equation and solve for the variable
we know that
0.10 x+0.25 y=3.45---------------> 10x+25y=345 equation (1)
x=y+10 equation (2)
substituting 2 in 1
10[y+10]+25y=345----> 10y+100+25y=345
35y=345-100-----------> y=245/35=7
x=y+10--------> x=7+10=17
Step 3: plug in the value of x and y from last step into the variables.
y=7--------> number of quarters coins
x=17-------> number of dimes coins
She has (7+17)=24 coins in total
Thus, 0.25x + 0.1(10+x) = 3.45
= 0.25x +1 +0.1 x = 3.45
= 0.35 x = 3.45 -1
= 0.35x = 2.45
x = 7
Therefore, the quarters are 7, while the dimes were 17,
Thus a total of 24 coins
Meg constructed triangle POQ and then used a compass and straightedge to accurately construct line segment OS, as shown in the figure below:

Measure of angle POS is 25 degrees, measure of angle POQ is 40 degrees
Measure of angle POS is 25 degrees, measure of angle POQ is 30 degrees
Measure of angle POS is 20 degrees, measure of angle POQ is 40 degrees
Measure of angle POS is 20 degrees, measure of angle POQ is 30 degrees
Answers
The correct answer is:
Measure of angle POS is 20 degrees, measure of angle POQ is 40 degrees
Explanation:
OS is an angle bisector of ∠POQ. This means it splits ∠POQ into two congruent pieces.
This tells us that ∠POS+∠SOQ = ∠POS+∠POS = ∠POQ.
If m∠POS = 20, this means that m∠POQ = 20+20 = 40°.

The length of the rectangular room is 12 feet.
To find the length of a rectangular room when the area and width are known, you can use the formula:
Area = Length x Width
Given that the area is 120 square feet and the width is 10 feet,
we can substitute these values into the formula:
120 = Length x 10
Length = 120 / 10
Length = 12

x = 40 + y
We solve the equation system for z:
1) x = 40 + y
2) y = 5z
3) x = 88 + z

Answers
We need to cancel out the negatives, so we need to simplify this.
To make things a bit easier for you, we can begin by counting out how many negatives we have. After counting, you should have a negative number count of 5. However, one of the negatives is apart of (-10x) so we'll have 4 negatives and then an extra negative in with 10x.
Remember that "-" could also be looked at as "-1."
So, if we break this down into smaller parts and substitute "-" into "-1," then this'll look like this :
-1 × -1 × -1 × -1 × (-10x) = -5
Remember that a negative times a negative is always a positive.
So, since there are four negatives, then you just multiply it all together.
This results in 1 × (-10x) = -5
Simplify.
-10x = -5
Now, you simply divide both sides by -10.
-10x ÷ -10 = -5 ÷ -10
Simplify.

Wendy took a trip from one city to another, a distance of 580 mi. she traveled part of the way by bus, which arrived at the train station just in time for wendy to complete her journey by train. the bus averaged 40 mi/h, and the train averaged 80 mi/h. the entire trip took 9 1 2 h. how long did wendy spend on the train?
Answers
and therefore, she took (580-x) mi by train, thus the time taken with train was (580-x)/80 hours.
Hence, x/40 +(580-x)/80 = 9.5 hours
80(x/40) +80 (580-x)/80 = (9.5)80
= 2x + 580-x = 760
x= 760-580
x = 180
Thus the train covered a distance of (580-x) =580-180 = 400
Hence, Wendy took 400/80 = 5 hours on the train
