Answer:
P = 16x+26y units
Step-by-step explanation:
Let the length is (x+8y) units
Width = (8x-x+5y) units
We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.
P = 2[(x+8y) + (8x-x+5y)]
= 2[(8x+8y+5y)]
= 2[8x+13y]
= 16x+26y
Hence, the required perimeter is 16x+26y.

Determine whether the ordered pair is a solution of the linear inequality.
x ≤ 3; (–2, 6)
Answer:
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].
Hence, (-2, 6) is a solution to the linear inequality.
Step-by-step explanation:
Given the linear inequality
x ≤ 3
substitute the value of x = -2
-2 ≤ 3
TRUE
It is clear that -2 is indeed less than 3. Thus, the ordered pair (-2, 6) is a solution to the linear inequality.
Also,
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].

What is 160/11 as a whole number
Answer:
14 6/11
Step-by-step explanation:
Let logp/n=5 and logm/n=9
Answer:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P
Andrea wants to mark off a quarter-mile course for a race, but all she has is a yardstick. There are 1,760 yards in a mile. How many yards does Andrea need to measure for her race course?
According to the given statement Andrea have to mark 440 yards out of 1760 for her race course.
The yard is defined as:A yard (yd) is a length unit used in various different systems, including US customary measures, Imperial units, and historic English units. It is 3 feet, 36 inches, or 0.9144 meters.
What exactly seems to be the conversion factor?A conversion factor seems to be a number that can be used to multiply and otherwise divide one set of units by another set of units. The right conversion factor must be used when converting to something like an equivalent value. For example, to convert inches to feet, the appropriate conversion value equals 12 inches equals 1 foot.
According to the given information:Want quarter-mile course for a race.
Total yards she has is a = 1760
We know that:
1 mile = 1760 yards

The length of RS is such that △RST∼△R′S′T′ will be 6 feet.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Given two triangles are similar △RST∼△R′S′T′
If two triangles are similar then the ratio of the corresponding side must be the same.
Therefore,
RS/R'S' = TS/T'S'
(12x + 2)/(5x + 1) = 9/4
By cross multiplication,
48x + 8 = 45x + 9
3x = 1
x = 1/3
Therefore,RS = 12(1/3) + 2

Answer:
6.5
Step-by-step explanation:
Look at image.
Hope it helps
The length of the hypotenuse in the right-angle triangle of length and base is 6.5 cm.
From the Pythagoras theorem, the sum of squares of the two sides of a right-angle triangle is equal to the square of the hypotenuse.
We can calculate the third side using Pythagoras' theorem, as the base and perpendicular sides are given.
Given:
Sides, x = 6 cm and y = 2.5 cm
From Pythagoras' theorem:
x² + y² = z²
6² + 2.5² = 6.5 cm
Hence, the length of the hypotenuse in the right-angle triangle is 6.5 cm.

Step-by-step explanation:

The required magnitude of the vector is √13. Option D is correct.
A graph is given, that shows the vector, the magnitude of the vector is to be determined.
Vector form is defined as representing any point in space that has both magnitude and direction. A point k in space is represented as a vector OKi + OKj, which denotes the vector line, OK joining the line from the origin O to the point k. The vector form is used to define a line or a plane in a 3D space.
From the figure,
given vector can be expressed as,
[tex]\bar v = 3\bar i+2\bar j[/tex]
now the magnitude of vactor,
[tex]|\bar v| = \sqrt{3^2+2^2}\\|\bar v| = \sqrt{9+4}\ \\|\bar v| = \sqrt{13}\[/tex]
Thus, the required magnitude of the vector is √13. Option D is correct.

Answer:
D) 121 degrees
Step-by-step explanation:
A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.
In this case, since supplementary angles add up to 180 degrees, we set up an equation:
<A+<B=180
(6x-19)+(11x-22)=180
17x-41=180
17x=221
x=13
Now we plug in x=13 for angle B:
11x-22
11(13)-22
143-22
121
Therefore, the measure of angle B is 121 degrees
