She walks 540 yards for 3 full laps around the park per day.
How to determine the distanceFrom the information given;
The longest part of the triangular park = 75 yards
The shortest part = 45 yards
Let's find the other part, using Pythagorean theorem;
a² = b² + c²
75² = 45² + c²
c² = 75² - 45²
Find the squares
c² = 5625 - 2025
c² = 3600
Make 'c' the subject
c = √3600
c = 60 yards
If she walks
75 + 60 + 45 yards per lap
180 yards per lap
For three laps, she walks
= 3 × 180
= 540 yards
Thus, she walks 540 yards for 3 full laps around the park per day.

Given △BAD AB = 3x - 4 ED = 24 CA = 12 BE = 3x Find x to the nearest hundredth.
Answer:
x = 10.67
Step-by-step explanation:
The triangles shown are similar, so corresponding sides are proportional. This lets us write a relation that can be solved for x.
SetupFor the given figure, we can write the proportion ...
AB/CA = DB/ED . . . . . . where DB = ED +BE
(3x-4)/12 = (24 +3x)/24 . . . . . . substitute given values
SolutionMultiplying by 24 gives ...
2(3x -4) = 3x +24
6x -8 = 3x +24 . . . . . eliminate parentheses
3x = 32 . . . . . . . . add 8-3x
x = 32/3 = 10 2/3 ≈ 10.67 . . . . . divide by 3 and convert to decimal
The value of x to the nearest hundredth is 10.67.

Step-by-step explanation:
Given sequence
2, 8, 14, 20, 26
Determine the pattern
2 + 6 = 8
8 + 6 = 14
14 + 6 =20
20 + 6 = 26
For each term, add 6 to get the next term
Determine the type of sequence
Since it continuously adds 6, the common difference is 6, which means it is an arithmetic sequence
Given the arithmetic sequence formula
aₙ = a₁ + d (n - 1)
a₁ = 1st term of a sequenceaₙ = nth term of a sequencen = nth positiond = Common differenceSubstitute values into the formula
aₙ = (2) + (6) (n - 1)
aₙ = 2 + 6 (n - 1)
aₙ = 2 + 6n - 6
aₙ = 2 - 6 + 6n

Hope this helps!! :)
Please let me know if you have any questions
Given sequence :-
2 , 8 , 14 , 20 , 26...Solution :-
We need to calculate the nth term of the given sequence.
Common difference (d) = 8 - 2 => 6First term of sequence (a) = 2We know that,
tn = a + (n - 1) dApplying the values here.
>> tn = 2 + (n - 1) 6
>> tn = 2 + (n - 1) × 6
>> tn = 2 + 6n - 6
>> tn = 6n - 4
Therefore, nth term of the sequence is (6n - 4).
Consider the line 4x + 2y = 8.
What is the slope of a line perpendicular to this line?
m1 x m2 = - 1
Rearrange 4x + 2y = 8.
4x + 2y = 8
-4x, then ÷ 2
y = - 4x + 8 / 2
y = - 2x + 4
m1 = - 2, find reciprocal of - 2, by placing 1 over the 2
So, - 2 will become - 1/2, but multiplying this gives us a positive 1. Thus, m2 = 1/2
m1 x m2 = - 1
-2 x 1/2 = - 1
That means slope perpendicular to the line
4x + 2y = 8 is y = 1/2x, where a half is the gradient/slope.
Ans: 1/2

28 grams of seeds cost $100 , and 14 grams of seeds cost $60. If you only have $70 and someone gives you $30 to buy 28 grams, how many grams of seeds would you give the person that gave you $30 if you paid $70?
Answer:
8.4 grams
Step-by-step explanation:
We have $70 to start and someone us another $30 for a total of $100. We pay $100 for 28 grams of seeds. If we assume the peron giving us $30 wants a fair share of the seeds, we would calculate an average cost per gram and use that to determine the grams of seeds that the $30 would have covered.
($100/28 grams) = $3.57/gram
($30/$3.57/gram) = 8.4 grams
Answer:
28 grams of seeds
Step-by-step explanation:
(This question is a little tricky)
Note that:
{28 grams of seeds = $100}
----------------------------------------
You have $70 already, and then someone gives you $30.
It means $70 + $30 = $100
So you have $100 now, you can buy 28 grams of seeds and give the person that gave you $30.

total in the ratio is 9
girls are 5/9 of total, and are 375
boys are 4/9 of total

The value of x is 11 1/2 OR 11.5
Calculating the measure of anglesFrom the question, we are to determine the value of x
In the given diagram, we have two isosceles triangles
Since base angles of isosceles triangles are equal,
Then, each of the base angles of the isosceles triangle is 68°
Then, we can write that
m ∠2 + 68° + 68° = 180° (Sum of angles in a triangle)
From the given information,
m ∠2 = 4x - 2
Then,
4x -2 + 68° + 68° = 180°
4x = 180 - 68 - 68 +2
4x = 46
x = 46/4
x = 11 1/2 OR 11.5
Hence, the value of x is 11 1/2 OR 11.5

For instance, this transformation shifts the parallelogram 3 units upward and 5 units to the right.A transformation in geometry is an action that moves, flips, or modifies a shape (referred to as the preimage) to produce a new shape (called the image). An example of a transformation is a translation, which moves every point in a figure uniformly and in one direction.Find the image of the given point under the given translation:

Kiran was trying to solve the equation 3x 8 = 7x - 8. She said, "The equation has no
solutions because the constant is the same." Do you agree with Kiran? Explain your
reasoning
The statement that the equation has no solutions because the constant is the same is true
How to determine the true statement?The equation is given as:
3x - 8 = 7x- 8
Add 8 to both sides
3x - 8 + 8= 7x- 8 + 8
Evaluate the like terms
3x = 7x
Divide both sides by x
3 = 7
The above equation is false, because 3 and 7 are not equal
This means that the statement that the equation has no solutions because the constant is the same is true
