Answer:
17 cm
Step-by-step explanation:
Rectangle perimeter: length*2 + width*2
Substitute width with "x".
Length is given as 15 cm
Perimeter is given as 64 cm
Plug in the values and solve for x.
64 = 2*15 + 2x
64 = 30+2x
2x = 34
x = 17
so width is 17 cm

7.find the equation of a circle with one of the diameters x+2y+8=0and passing through the intersection of a circle x²+y²+2=0 and x²+y²-3y=0.
ans:
[tex]\bold=4x²+4y²+22x+21y=0.}[/tex]
Answer:
See belowStep-by-step explanation:
Find the intersection of circles
x² + y² + 2x = 0 and x² + y² - 3y = 0Subtract the equations to find:
2x = -3y ⇒ y = -2/3xBy substitution find the points:
(0, 0) and (-1.385, 0.923)Find midpoint between these two points:
x = (0- 1.385)/2 = -0.6925 , y = (0 + 0.923)/2 = 0.4615Find perpendicular bisector passing through this point:
y - 0.4615 = 3/2(x + 0.6925)y = 1.5x + 0.4615 + 1.5(0.6925)y = 1.5x + 1.50025Find intersection of the lines, it is the center:
y = 1.5x + 1.50025x + 2y + 8 = 0Solving we get:
x = -2,75, y = -2.625Find radius, the distance from center to point (0, 0) and get equation of circle:
(x + 2.75)² + (y + 2.625)² = (0 + 2.75)² + (0 + 2.625)²x² + 5.5x + y² + 5.25y = 04x² + 22x + y² + 21y = 04x² + 4y² + 22x + 21y = 0Answer:

Answer:
2nd option:
8x+2y=32
x+y=7
Step-by-step explanation:
Answer:
It is in fact the second one.
Step-by-step explanation:
It says that he bought a total of 7 tickets and it cost $32.
x represents the number of adult tickets and y represents the number of chid tickets.
So:
x + y = 7 because the adding the number of adult and child tickets should equal the total number bought.
and
8x + 2y = 32 because each adult ticket was 8 dollars and each child was 2 and the total should add up to 32
solve
3x+3y=18
2x-2y=4

They made a down payment of 42,000 and took out a mortgage for the rest. Over the course of 15 years they made monthly payments of $2,447.19 on their mortgage until it was paid off.
(a) What was the total amount they ended up paying for the house (including the down payment and monthly payments)?
(b) How much interest did they pay on the mortgage?
Answer:
Step-by-step explanation:
(a)Mortgage = 332000 - 42000 = 290000
15 * 12 = 180 months
Total monthly payments = 180 * 2447.19 =440494.2
Total = 440494.2 + 42000 = 482494.2
(b) Interest = 482494.2 -290000
= 192494.2

a) 482,494.20

Two cyclists, 68 miles apart, start riding toward each other at the same time. One cycles 3 miles per hour faster than the other, and they meet after 4 hours of riding.
a. Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r to represent the speed of the slower cyclist.
b. What are the speeds of the two cyclists? _______________
Answer:
4r + 4(r + 3) = 68
r = 7 miles per hour
r + 3 = 10 miles per hour
Step-by-step explanation:
distance = rate * time
a)
4r + 4(r + 3) = 68
Distribute
4r + 4r + 12 = 68
8r + 12 = 68
8r = 56
r = 7 miles per hour
r + 3 = 10 miles per hour
a) The given equation using the information as it is given above that can be solved to answer this problem is 4r + 4(r+3) = 68
b) The speed of both cyclists are 3mi/hr and 10mi/hr respectively
The formula for calculating the distance covered is expressed as:
Distance = speed * time
Let the speed covered by one cyclist be t
If one cycles 3 miles per hour faster than the other, the speed of the other will be t + 3
If both meet after 4 hours of riding, then their time will be 4 hours
Distance covered the first cyclist = 4r
Distance covered by the second = 4(r+3)
If the two cyclists are 68 miles apart, then:
4r + 4(r+3) = 68
a) The given equation using the information as it is given above that can be solved to answer this problem is 4r + 4(r+3) = 68
b) Expand the equation in a to get "r"
4r + 4r + 12 = 68
8r + 12 = 68
8r = 68 - 12
8r = 56
r = 56/8
r = 7miles per hour
Speed of the first cyclist = 7mi/hr
Speed of the second cyclist = 3 + 7mi/hr = 10mi/hr
Hence the speed of both cyclists are 3mi/hr and 10mi/hr respectively

C. 81 in
D. 324 in?
Need help ASAP please check the picture
Answer:
C is the answer
Step-by-step explanation:
First find the area of the circle -
Use pi times r^2
Since the answers are in pi form, we just need to do the "r^2" part. 3 is the radius, so 3 x 3 = 9. Now that we have found the area of the circle, we will need to multiply the area of the circle by the height of the cylinder. (9pi)(9) = 81pi cubic units. 81pi cubic units is the answer.

What is the center of the circle (x+7)^2+(y+4)^2=25
9514 1404 393
Answer:
(-7, -4)
Step-by-step explanation:
Compare the given equation to the standard form equation for a circle with center (h, k) and radius r.
(x -h)^2 +(y -k)^2 = r^2
You see that ...
-h = +7 ⇒ h = -7
-k = +4 ⇒ k = -4
Then the center is ...
(h, k) = (-7, -4)
__
The radius is ...
r^2 = 25 ⇒ r = √25 = 5 . . . radius of the circle
