PLs, help me with this question
Answer:
See below.
Step-by-step explanation:
Perimeter: use the Distance Formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance from (-3, 4) to (4, 5) is
[tex]\sqrt{(5-4)^2+(4-(-3))^2}=\sqrt{1+49}=\sqrt{50}=5\sqrt{2}[/tex]
Distance from (4, 5) to (2, -3) is
[tex]\sqrt{(2-4)^2+(-3-5)^2}=\sqrt{4+64}=\sqrt{68}=2\sqrt{17}[/tex]
Distance from (2, -3) to (-4, 4) is
[tex]\sqrt{(-4-2)^2+(-4-(-3))}=\sqrt{36+1}=\sqrt{37}[/tex]
Distance from (-4, 4) to (-3, 4) is
[tex]\sqrt{(-4-(-3))^2+(4-(-4))^2}=\sqrt{1+64}=\sqrt{65}[/tex]
The perimeter is the sum of all these distances.
Area:
To find the area of the figure, one method is to draw a rectangle around the entire figure, then add line segments that cut up the unwanted area into rectangles and triangles, add those areas together, then subtract the total from the area of the surrounding rectangle. See the attached figure.
The surrounding rectangle has area 8 x 9 = 72 square units.
The unwanted areas (green rectangles and four triangles). Remember, the area of a triangle is (1/2)(length)(width).
Rectangle A: 1 x 1 = 1 square unit
Triangle B: (1/2)(7)(1) = 3.5 square units
Triangle C: (1/2)(8)(1) = 4 square units
Triangle D: (1/2)(8)(2) = 8 square units
Triangle E: (1/2)(6)(1) = 3 square units
Rectangle F: 2 x 1 = 2 square units
Total of unwanted area: 1 + 3.5 + 4 + 8 + 3 + 2 = 21.5 square units
Subtract this total from the surrounding rectangle's area to get
72 - 21.5 = 50.5 square units
A ski slope is 250 yards long with a vertical drop of 100 yards. Find the angle of depression of the
slope.
Step-by-step explanation:
would you still like me to help you with this question
Angle of depression of the slope is 24. degree.
Angle of depression is equal to the angle of elevation.
sine = the vertical drop/ the ski slope
sine = 100/250
= 2/5 = 0.4.
sine - 1 (0.4) = 23.57 which is about 24 degree.
Therefore, the correct angle of depression of the slope is approximately 24 degree.

given a set of numbers (0,1,2,3,4,5,6) if one of the set is chosen at random, find the
probability that the number is a solution of 3x-4 < 11
Answer:
This probability is 5/7
Step-by-step explanation:
Rewriting this problem may make it appear to be more manageable.
The probability that the number is a solution of 3x-4 < 1 simplies to "x < 5".
This probability is 5/7, since {0, 1, 2, 3, 4} are all less than 5.

What volume of coppr ( density 8.96g/cm3)would be needed to balance a 2.28 cm3sample of lead (density 11.4g/cm30 on a two-pan laboratory balance
Answer:
2.9 cm³
Step-by-step explanation:
Note: For the copper and the lead to balance, they must have thesame mass.
Applying,
D' = m'/V.................... Equation 1
Where D' = density of the lead, m' = mass of the lead, V = Volume of the lead.
make m' the subject of the equation
m' = D'V................ Equation 2
From the question,
Given: D' = 11.4 g/cm³, V = 2.28 cm³
Substitute these values into equation 2
m' = (11.4×2.28)
m' = 25.992 g
Similarly,
for copper,
D = m/V............... Equation 3
Where D = density of copper, m = mass of copper, V = volume of copper.
make V the subject of the equation
V = m/D.............. Equation 4
where, m = m' = 25.992 g
Given: D = 8.96 g/cm³
Substitute these values into equation 4
V = 25.992/8.96
V = 2.9 cm³

round 4.776 to the nearest hundred
The round off of 4.776 to the nearest hundred results in 4.800.
To round 4.776 to the nearest hundred
Focus at the digit in the hundredth's place, which is the second decimal place.
In this case, the digit in the hundredth's place is 7.
Since 7 is greater than or equal to 5, we round up the previous digit, which is 7.
Therefore, rounding 4.776 to the nearest hundred results in 4.800.

1) If the perimeter of triangle STU is 125 cm, and segments TW, VW, and VT measure 21 cm, 30 cm, and 24 cm, respectively, what is the length of segment SU?
GIVEN: The perimeter of triangle STU is 125.
The segments TW=21 cm
VW=30 cm
VT=24 cm
TO FIND: The length of the segment SU.
SOLUTION:
As corresponding sides must be same. so we have,
[tex]\frac{TV}{TS}=\frac{TW}{TU}\\\\ \frac{24}{TS}=\frac{21}{TU}\\\frac{TU}{TS}=\frac{7}{8}=k(say)\\[/tex]
Then, TU=7k and TS=8k
[tex]\frac{TV}{TS}=\frac{VW}{SU}\\\\ \frac{24}{TS}=\frac{30}{SU}\\\frac{24}{8k}=\frac{30}{SU}\\SU=10k[/tex]
As the perimeter of triangle STU is 125.
so,
8·k+7·k+10·k=125
⇒25.k=125
⇒k=5
Therefore, SU=10×5=50

indentify the center and radius: (x + 4)2 + (y + 5)2 = 64
please helppp!!
Answer:
4th option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 5)² = 64 ← is in standard form
with h = - 4, k = - 5 and r = [tex]\sqrt{64}[/tex] = 8
centre = (- 4, - 5) and r = 8

?????????????????????????????????????????/
Answer:
Your value of z is 71 degrees. The value of x is 11.
Step-by-step explanation:
You can determine the value of z by knowing that z and the 71 angle are vertical angles. Vertical angles are congruent to each other. We know that the x angle and the 71 angle are supplementary, or that they equal 180. So, set up the equations, and solve for x. :
[tex]180=71+(9x+10)\\180=81+9x\\99=9x\\x=11\\[/tex]
