Answer: C
Step-by-step explanation:
the equation for X is
[tex]\frac{2+x}{2} =\frac{8}{1}[/tex] use proportion to solve
2 + x = 16
x = 14
(14,y)
The equation for Y is
[tex]\frac{-1+y}{2} =\frac{3}{1}[/tex] use proportion to solve
-1 + y = 6
y = 7
(14,7)
now use the distance formula
(14,7) (2,-1)
which gets you 14.4 or C

The error made by Tnaya in constructing the box plot is the first quartile and third quartile depicited is wrong.
What is a box plot?
A box plot is used to study the distribution and level of a set of data. The box plot consists of two lines known as whiskers and a box. The first whisker represents the minimum value and the last whisker represents the maximum value.
On the box, the first line to the left represents the first quartile. 25% of the score represents the lower quartile. The next line on the box represents the median. 50% of the score represents the median. The third line on the box represents the third quartile. 75% of the scores represents the third quartile.
For the data given, the:
Minimum value = 12 Maximum value = 22Median = 16 First quartile = 11/4 = 2.75 = 13 Third quartile = 3/4 x 11 = 8.25 = 23To learn more about median, please check: https://brainly.com/question/20434777

Consider the two circles shown.
To show that circle P is similar to circle Q, circle P is translated t units to the right. The image is then dilated about its center by a scale factor of s.
What are the values of t and s?
Show me:
(t) What is the horizontal distance between the center of circle P to the center of circle Q?
(s) What is the scale factor dilating from circle P to circle Q?
The similar circles P and Q can be made equal by dilation and translation
The horizontal distance between the center of circles P and Q is 11.70 unitsThe scale factor of dilation from circle P to Q is 2.5The horizontal distance between their centers?From the figure, we have the centers to be:
P = (-5,4)
Q = (6,8)
The distance is then calculated using:
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have:
d = √(6 + 5)^2 + (8 - 4)^2
Evaluate the sum
d = √137
Evaluate the root
d = 11.70
Hence, the horizontal distance between the center of circles P and Q is 11.70 units
The scale factor of dilation from circle P to QWe have their radius to be:
P = 2
Q = 5
Divide the radius of Q by P to determine the scale factor (k)
k = Q/P
k = 5/2
k = 2.5
Hence, the scale factor of dilation from circle P to Q is 2.5

Jack is 3 times as old as Lacy. 9 years ago the sum of their ages was 22 . How old are they now?
Answer:
Jack is 31
Lacy is 10
Step-by-step explanation:
x - 9 = 22
since jack is 3 times as old as lacy,
the formula is
3x - 9 = 22
3x = 31
x = 10.3
So Jack is 31
And Lacy is 10
To prove this, subract 9 (years) from both ages
It will give you an approximate sum of 22 years for both their ages, as the question states
Since Lacy is a little over 10 years old, Jack is 31 instead of 30

How many factors do numbers of the form p^n and q^m have if p and q are two different prime numbers and m and n are natural numbers?
The only common factor between these two numbers will be 1.
How many factors do these numbers share?
Remember that any number can be decomposed as a product of prime numbers. For example for 18 we have:
18 = 2*3*3
There 18 is written as a product of its prime factors.
Now, for our case of p^n and q^m we will have:
p^n = P = p*p*p...*p n times.
q^m = Q = q*q*q*...*q m times.
Now, notice that because q and p are primes, there is no common factor in these two decompositions. (and we can't decompose it furthermore). Then we conclude that the only factor that these numbers share is the trivial one, which is 1.

If two complementary angles are placed side by side, they form a(n)
angle. Side-by-side angles that share a ray and a vertex are called
angles.
of comnlementary angles you can solve for the
Answer:
Two angles whose sides are opposite rays are called vertical angles. Two coplanar angles with a common side, a common vertex, and no common interior points are called adjacent angles.
Further explanation
Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. They share a vertex and side, but do not overlap. The example is shown in the picture below.
Where ∠1 and ∠2 are adjacent angles, ∠ABC and ∠1 are NOT adjacent angles because ∠ABC overlaps ∠1.
Vertical Angles are two angles whose sides form two pairs of opposite rays (straight lines). Vertical angles are located across from one another in the corners of the "X" formed by the two straight lines. The example is shown in the picture below.
Where ∠1 and ∠2 are vertical angles, ∠3 and ∠4 are vertical angles, Vertical angles are not adjacent. ∠1 and ∠3 are not vertical angles (they are a linear pair) and Vertical angles are always equal in measure.

A dairy farmer plans to enclose a rectangular pasture adjacent to a river. To provide enough grass for the herd, the pasture must contain 18 square meters. No fencing is required along the river. What dimensions will use the least amount of fencing?
Answer:
390 m (perpendicular to river) x 780 m (parallel to river)
Step-by-step explanation:
Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.
The total area and length of fence required are given by:
Rewriting the length of fence as a function of only x:
The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:
If x = 390 m, then:
The dimensions that will use the least amount of fencing are 390 m x 780 m

C.

D.

E.

The rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.
What is area?Area is the amount of space occupied by a two dimensional shape or object.
A rectangle is shown with a length and height of 6 ft. Hence:
Area = (6 * 6) = 36 ft²
Perimeter = 2(6 + 6) = 24 ft
For 12 ft by 3 ft:
Area = (12 * 3) = 36 ft²
Perimeter = 2(12 + 3) = 30 ft
For 9 ft by 4 ft:
Area = (9 * 4) = 36 ft²
Perimeter = 2(9 + 4) = 26 ft
For 8 ft by 3 ft:
Area = (8 * 3) = 24 ft²
Perimeter = 2(8 + 3) = 24 ft
For 7 ft by 4 ft:
Area = (7 * 4) = 28 ft²
Perimeter = 2(7 + 4) = 26 ft
For 18 ft by 2 ft:
Area = (18 * 2) = 36 ft²
Perimeter = 2(18 + 2) = 40 ft

-3b + 2.5 = 4
Answer: b = -0.5
Step-by-step explanation:
Given
-3b + 2.5 = 4
Subtract 2.5 on both sides
-3b + 2.5 - 2.5 = 4 - 2.5
-3b = 1.5
Divide -3 on both sides
-3b / -3 = 1.5 / -3
[tex]\boxed{b=-0.5}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
[tex]\Longrightarrow: \boxed{\sf{b=-0.5}}[/tex]
Step-by-step explanation:
To solve this problem, all you have to do is isolate the term of b from one side of the equation.
-3b+2.5=4First, you have to subtract by 2.5 from both sides.
→ -3b+2.5-2.5=4-2.5
Solve.
Add or subtract the numbers from left to right.
→ -3b=1.5
Then, you divide by -3 from both sides.
→ -3b/-3=1.5/-3
Solve.
Divide the numbers from left to right.
→ 1.5/-3=-0.5
b=-0.5
Therefore, the correct answer is b=-0.5.I hope this helps! Let me know if you have any questions.
