Firstly let's find hypotenuse(let it will be "n" of smaller triangle
Let use Pythagorean theorem
[tex]a^{2} + {b}^{2} = {n}^{2} \\ {20}^{2} + {10}^{2} = {n}^{2} \\ n = \sqrt{500} [/tex]
Now we need to find hypotenuse(x) of bigger triangle
[tex] {c}^{2} + {n}^{2} = {x}^{2} \\ {9}^{2} + { \sqrt{500} }^{2} = {x}^{2} \\ x = \sqrt{581} [/tex]
The value of x must be rounded to 1 DP, so
[tex] \sqrt{581} = 24.1039... \\ \sqrt{581} \simeq \: 24.1[/tex]
Answer: x=24.1

Check that x=2 and y=5 is a solution of both equations below:
X+2y=12
3x+6y=36 *
Answers
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 5 into the left side of the equations and if equal to the right side then they are a solution.
x + 2y = 2 + 2(5) = 2 + 10 = 12 ← True
3x + 6y = 3(2) + 6(5) = 6 + 30 = 36 ← True
Thus x = 2, y = 5 is a solution to both equations

each leg of a 45 45 90 triangle measures 12cm, what is the length of the hypotenuse
Answers
Answer:
12√2
Step-by-step explanation:
Use the Pythagorean Theorem here:
(12 cm)^2 + (12 cm)^2 = 288 cm^2.
The length of the hypotenuse is √288 = (√4)(√72) = 2(√36)(√2) = 12√2
Given that both legs of a 45, 45, and 90 degree triangle are 12cm, find out the length of the hypotenuse.
To solve for the hypotenuse, we will use the Pythagorean Theorem.
The formula to find the hypotenuse is:
a^2 + b^2 = c ^2
We already know that both legs are 12cm, so we can plug them in.
12^2 + 12^2 = c^2
Solve.
144 + 144 = c^2
Add.
288 = c^2
Find the square root of 288.
sqrt(288) = 16.97
Therefore, the square root of 288 is 16.97
If we round 16.97 to 17 and then square it, that would equal 289.
So, the best choice is to leave it as 16.97.
Thus, the length of the hypotenuse is 16.97 or 17 if you want to round it.

Answers
Answer:
A=238.87 cm
Step-by-step explanation:
First find the area for the rectangle
11*23= 253 cm
then find the area for the little circles
D=3cm so r=1.5cm
Now plug in values into formula
A=π(1.5)^2
A=π(2.25)
A=3.14(2.25)=7.065cm
A=7.065cm since there are two circles
7.065*2=14.13
Now subtract the area of the circles from the rectangle
253-14.13=238.87
Find the point that lies on the line described by the equation below. y - 8 = - 3 (x-6)
Answers
Answer:
B. (6, 8)
Step-by-step explanation:
To figure this out, you can plug in the coordinates to see if you get matching answers. Since you believe answer "B," is correct, we can check:
y - 8 = -3(x - 6)
8 - 8 = -3(6 - 6)
0 = -3(0)
0 = 0
Since the answers match, that makes answer "B," correct.

c.) the measure of DE is 48°, and triangle BCD is not isosceles.
d.) the measure of DE is 83°, and triangle BCD is not isosceles.
Answers
Answer:
Correct option: A
Step-by-step explanation:
The angle BDC inscribe the arc mBC, so we have that:
mBDC = (1/2) * mBC
mBDC = (1/2) * 118 = 59°
From the secants relation in a circle, we have that:
mA = (1/2) * (mBC - mDE)
35 = (1/2) * (118 - mDE)
70 = 118 - mDE
mDE = 48°
The sum of the arcs is 360°, so we have:
mBC + mCD + mDE + mBE = 360
118 + mCD + 48 + 76 = 360
mCD = 360 - 118 - 48 - 76 = 118°
The angle mCBD inscribes the arc mCD, so we have:
mCBD = (1/2) * mCD = (1/2) * 118 = 59°
The angles mCBD and mBDC are equal, so the triangle is isosceles.
Correct option: A

A rectangular building has a perimeter of 208 meters. It’s area is 2415 square meters. What are the dimensions of the building?
Answers
Answer:
Step-by-step explanation:
Perimeter of rectangle = 208 m
2*(l + w) = 208 {divide both sides by 2}
l +w = 208/2
l +w = 104
l = 104 - w
Area of rectangle = 2415 square meters
l*w = 2415
Substitute l = 104 - w in the above equation,
(104 - w ) *w = 2415
104w - w² = 2415
0 = 2415 - 104w + w²
w² - 104w + 2415 = 0
Sum = -104
Product = 2415
Factors = (-69) , (-35)
w² - 35w - 69w + (-69)*(-35) = 0
w(w - 35) - 69(w - 35) = 0
(w -35)(w -69)
w - 35 = 0 ; w -69 = 0
w = 35 ; w = 69
The dimensions of the building: 35 , 69

A stackable CD rack holds 20 CDs and costs $3. Mark has a collection of 120 CDs. How much will it cost him to buy enough racks to hold all of his CDs?
Answers
Answer:
You would need $18 total to buy the racks needed.
Step-by-step explanation:
First, every 20 CDs needs a new rack, so you would divide 120 by 20.
120 / 20 = 6 racks
Second, you would multiply the price ($3) of a rack by how many racks needed.
3 * 6 = $18
Graceland Farm has two cylindrical water tanks, one for cold and a second for hot water. The hot water tank has a diameter of 8 feet and can hold 503 cubic feet of water. If the cold water tank is shorter than the hot water tank, than how tall can the cold water tank be? Is there more than one solution?
Answers
Answer:
h < 10 or (0, 10)
The problem has multiple solutions
Step-by-step explanation:
In this case we can calculate the height of the hot water tank because we know the diameter and volume. The formula is:
V = pi * (r ^ 2) * h
we solve for h:
h = V / (pi * r ^ 2)
the radius is half the diameter, that is, r = d / 2; r = 8/2 = 4
replacing:
h = 503 / (3.1413 * 4 ^ 2)
h = 10
the problem has multiple solutions since they say that it is shorter, shorter is a number less than 10.
solution: h <10 or (0, 10)

Step-by-step explanation:so it is easiest to do one persons costs then just multiply it by 4 to get the cost of 4 people. so first for one person..... (their travel is) 130 + (hotel x 7 days) 60 x 7 + (spending money) 350 =900 . now multiply this by 4 = 3600
Let's start off by working out the cost for one person. This person has to spend 130 pounds on travel and have 350 pounds of spending money. So far that is 130+350 = 480 pounds. Then it says the hotel costs 60 pounds per day. At 7 days, it will cost one person 7*60 = 420 pounds. This adds onto the 480 to get 420+480 = 900.
Therefore, each person will need 900 pounds to go on a 7 day trip. If we had 4 people going, then 4*900 = 3600 pounds is needed total.
