Answer:
x=9
Step-by-step explanation:
The triangle is equilateral which means the sides are equal.
x+9 = 2x
Subtract x from each side
x+9-x = 2x-x
9 =x

The area of two similar triangles are 50dm^2 and 32dm^2. The sum of their perimeters is 117dm. What us the perimeters of each of these triangle?
Answer:
Perimeter of one triangle is 65 dm
Perimeter of other triangle is 52 dm
Step-by-step explanation:
Please remember the concept
If sides are in the ratio of a:b
Then the area in the ratio of [tex]a^{2} :b^{2}[/tex]
It is given sum of their perimeter is 117.
Let the small triangle has perimeter as x.
So, perimeter of big triangle is 117-x.
So, we can set up equation as
[tex]\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }[/tex]
Cross multiply
50(117-x)^2 =32x^2
Expand the left side
50[tex](13689 -234x+x^{2} )[/tex]=[tex]32x^{2}[/tex]
Distribute the left side
684450-11700x+[tex]50x^{2}[/tex]=[tex]32x^{2}[/tex]
Subtract both sides [tex]32x^{2}[/tex] and rewrite it [tex]18x^{2} -11700x+684450=0[/tex]
Solve this quadratic for x.
Divide both sides of the equation by 18 to simplify.
[tex]x^{2}[/tex]-650 x+38025=0
Now, if possible let's factor
Find two integers whose multiplication is 38025 but adds to -650.
-65 and -585 works.
So, we can rewrite it as
(x -65)(x-585) =0
Solve them using zero product property
x=65, x=585
So, x=65 works here.
So, perimeter of one triangle is 65 dm
Perimeter of other triangle is 117-65= 52 dm

A bag contains 25 marbles of the same size that are yellow, green, and purple. The probability of picking a yellow marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a purple marble from the bag and then classify the probability of picking a purple marble as likely or not likely to occur.
Answer:
Step-by-step explanation:
30% is the likelihood of picking a purple marble because 20% of 25 is 5 and 50% of 25 is 12.5 which leaves 7.5 marbles left (purple) and 7.5/25 = .30 which you multiply by 100 to get a percentage of 30
you are less likely to pick a purple marble than a green marble, but you have the least chance of picking a yellow marble

Answer:
1: the wooden part is 3.725 kilograms.
2: 10 Children
Answer:
1 3.725 kg of wood
2 10
Step-by-step explanation:
For question 1 you multiply the total weight by 3/4 to find the weight of the metal, you then subtract this from the total to find the weight of the wood
For question 2 you look at it as a fraction 1/3 kids + 2/3 adults equal 30, since there are twice as many adults. Then you multiply 30 by 1/3 and get 10
D) 4. Mrs. Smith wants to purchase table pads for her circular
dining room table. If the table has a diameter of 3 feet and
the pads cost 50 cents per square foot, approximately how
much will the table pads cost? Use 3.14 fora.
C
Answer: 3.53
Step-by-step explanation:
The cost for the table pads that Mrs. Smith will have to pay for her circular dining room table is $3.5325 approx
What is the area of a circle?If the considered circle has got is radius of 'r' units. Then, its area is calculated as:
[tex]A = \pi r^2 \: \rm unit^2[/tex]
where [tex]\pi = 3.14159...[/tex]
For this case, we are provided that:
Diameter of the circular dining table of Mrs. Smith = 3 feet
Thus, as radius is half of diameter, thus, radius of table = 3/2 = 1.5 feet
We find the area of the table since the area of the table pad that will be used for table will be equal to the area of the table because it will be applied all over the table.
The area of the table pad = area of the table = [tex]\pi (1.5)^2 \approx 3.14 \times (1.5)^2 = 7.065 \: \rm ft^2[/tex]
For each sq. foot, Mrs. Smith had to pay 50 cents = 0.5 dollars
Thus, for 7.065 sq. feet, the cost would be:
[tex]0.5 \times 7.065 = 3.5325[/tex] (in dollars)
Thus, the cost for the table pads that Mrs. Smith will have to pay for her circular dining room table is $3.5325 approx

Answer: y=5x+4
Step-by-step explanation:
Remember this
Slope-Intercept form: y=mx+b
m is the slope (5)
b is the y-intercept (4)
So your equation is
y=5x+4
Answer:
y = 5x + 4
Step-by-step explanation:
y - 4 = 5(x - 0)
That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -
y = 5x + 4

A square pool has a volume 4,086 cubic feet and depth 9 feet. A couple builds a fence 3.5 feet high around the pool. How many square feet of fencing surround the pool?
Answer:
Are they going to build the fence on the edge of the pool? How are they going to get into the pool? This question is illogical, however....
Step-by-step explanation:
A square pool is also wierd.
Volume Pool = side × side × depth
Volume Pool / depth = side² solve for side
side² = Volume Pool / depth
the fence is 3.5 feet tall
Fencing sqft one side = side × fence height for ONE side
Total Fencing = 4 × Fencing sqft one side
side² = 3464 ft³ / 8 ft
= 422 ft²
side = √422 ft²
= 20.54 ft
Fencing area one side = 20.54 × 3.5
= 71.899 ft²
Total fencing = 4× 71.899 ft²
= 287.6 ft² to the nearest tenth <-------------------- FINAL ANSWER
