The vertices of a triangle are A (4,-2), B(4,-4), C(12, -4). If the triangle is dilated by a scale factor of 1/4 what will be the coordinates of C'?
Answer:
(3, -1)
Step-by-step explanation:
12×1/4=3
-4×1/4=-1
The coordinates of C' after dilation with a scale factor of 1/4 are (7, -3).
To find the coordinates of C' after dilation, we need to apply the scale factor to the original coordinates of C (12, -4). Since the triangle is dilated with respect to the origin, we can calculate the new coordinates by simply multiplying the original coordinates by the scale factor, which is 1/4.
C' coordinates: (12 * 1/4, -4 * 1/4) = (3, -1)
However, since the triangle is not dilated with respect to the origin, we need to adjust the coordinates according to the translation of the dilation center. In this case, the dilation center is at vertex A (4, -2).
Translation vector: (4 - 0, -2 - 0) = (4, -2)
Final coordinates of C': (3 + 4, -1 - 2) = (7, -3)
So, the coordinates of C' after the dilation are (7, -3).

The formula P = a + b + c gives the perimeter P of a triangle with side lengths a, b, and c. How much greater is the perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yards than the perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards?
Answer:
40 yards greater
Step-by-step explanation:
Perimeter of a triangle, P = a + b + c
perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard
P = a + b + c
= (92 + 95 + 84) yards
= 271 yards
perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards
P = a + b + c
= (85 + 90 + 56) yards
= 231 yards
perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard is 40 YARDS GREATER than perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards
Greta has budgeted $1,500 to have a concrete patio poured in her backyard like the one shown. The cost per square foot of the concrete is $5.50. Find the cost of the patio to determine if Greta has budgeted enough money to complete the project.
Answer:
Yes the amount Greta has budgeted ($1,500) is enough to complete the project which will cost $1,443.75
Step-by-step explanation:
The amount Greta has budgeted to have a concrete patio = $1,500
The cost (per square foot) of the concrete, C/Ft² = $5.50/ft²
From the dimension of the backyard, we have;
The total area, A = The area of a rectangle + The area of a trapezium
The area of the rectangle = 6 ft. × 28 ft. = 168 ft.²
The area of the trapezium = (8 ft. + (28 ft. - 15 ft.))/2 × (15 ft. - 6 ft.) = ((8 ft. + 13 ft.)/2) × 9 ft. = 94.5 ft.²
The total area, A = 168 ft.² + 94.5 ft.² = 262.5 ft.²
The total cost of the concrete, C = A × C/Ft²
∴ C = 262.5 ft.² × $5.50/ft² = $1,443.75
Therefore, given that Greta budgeted $1,500 for the project which is more than the $1,443.75 required, Greta has budgeted enough money to complete the project

find 2 sets of numbers
Answer:
3,3,4,6,6
4,4,5,6,7
5,5,6,6,8
Step-by-step explanation:
mode = n
median= n+1
mean = n+2
Range = n+3
let sets:
a,b,c,d,e
mode = n, at least two of them are the same and equal to n
n,n,c,d,e
median belong to the set, in ascending order:
n,n,n+1,d,e
which means d,e ≥ n+1, d≠e
mean is n+2
5(n+2)=n+n+n+1+d+e
2n+9=d+e
Assume e is the maximum:
Range is n+3:
e-n=n+3
e=2n+3
d=6≥n+1
n≤5,
Set is n,n,n+1,6,n+3
n+1≤6≤n+3

Answer:
Step-by-step explanation: sleep
The triangle with sides 9 , 12 and 14 is an acute triangle
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the Triangle be ΔABC
Let the three sides of the Triangle be
First side = AB
Second side = BC
Third side = CA
Now , the three sides are having lengths as
AB = 9
BC = 12
CA = 14
Now , from the Pythagoras Theorem ,
If , base² + height² = hypotenuse² , it is a right angled triangle
If , base² + height² > hypotenuse² , it is a acute angled triangle
If , base² + height² < hypotenuse² , it is a obtuse angled triangle
So , substituting the values , we get
AB² + BC² > AC²
So ,
9² + 12² > 14²
81 + 144 > 196
225 > 196
Therefore , the triangle ABC is an acute angled triangle
Hence , The triangle with sides 9 , 12 and 14 is an acute triangle

Avannah needs to buy a bag of dog food that will last for 2 weeks (14 days). She estimates that a 20 lb bag will be enough. Is she correct?
Answer:
Yes, she is correct.
Step-by-step explanation:
In the question it is given that Avannah wants to buy food for her dog that may lasts for 2 weeks (or 14 days). Dogs must serve food according to their breed and their weight. The diet of every dog is different. Avannah needs to feed her dog three times a day. So a 20 lb bag of food is enough for her to feed her dog for 2 weeks.
So it is the correct decision to get a 20 lb bag of food for her dog. It will last for 14 days.
