Answers
Answer: D
Step-by-step explanation:
The slopes of two perpendicular lines are negative reciprocals of each other
The slope of this line is -1/4, the reciprocal is just the flipped fraction which is -4/1 or 4. Since it is a negative reciprocal you multiply it by -1. 2 negatives multiplied equals a positive so the slope of the perpendicular line is 4
y=mx + c ....(1)general line eqn)
y=-(1/4x) - 9 .....(2)
Comparing (1) and (2)
m=-1/4
Since both lines are
perpendicular
M=-1/m
Where M=gradient of other line
M=-1/(-1/4)
= -1 x - 4/1
=4
Therefore the gradient of the
other line is 4

Applying the inscribed angle theorem, we have:
1. m∠ABC = 79°
2. x = 10
What is the Inscribe Angled Theorem?The inscribed angle theorem states that the measure of an inscribed angle = 1/2(measure of intercepted arc).
Thus:
1. Find m∠ABC:
m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]
Substitute
m∠ABC = 1/2(360 - 94 - 108)
m∠ABC = 79°
2. Find the value of x:
m∠DEF = 1/2(DF) [inscribed angle theorem]
Substitute
51 = 1/2(14x - 38)
2(51) = 14x - 38
102 = 14x - 38
102 + 38 = 14x
140 = 14x
10 = x
x = 10

Answer:
so I don't know how to to take an image but I can try to explain
so here it goes
you can use either elimination method or the substitution method if you use the elimination method then you will have to either pick between using the X coordinate or the y coordinate I choose the X coordinate so the top equation multiply by 2 and the lower equation x by 3 you will end up with 6 x plus 16 y is equals to 14 and 6 x - 6y is equals to -30 subtract the both equations and end up with 0 + 22 y is equals to 44 hence

The thickness of a metallic tube is 1 cm and the inner diameter of the tube is 12cm. Fjnd the weight of 1 m long tube,if the density of the metal is 7.8 g/cm^3
Answers
Answer:
31.869 kg.
Step-by-Step Explanation:
Inner radius,r=12/2=6cm
thickness=1cm
so,outer radius,R=6+1=7cm
height,h=1m=100cm
volume=pi×(R^2-r^2)×h
=22/7×(7^2-6^2)×100
=22/7×(49-36)×100
=22/7×13×100
286/7×100
=28600/7
since,density=7.7gm/cm^3
also,weight=volume×density
weight=28600/7×7.7gm
=31460gm
or,31.46 kg

What is the slope of the line through the points (10,4)and (7,3) write your answer in simplest form
Answers
Answer:
1/3
Step-by-step explanation:
to find the slope of two points the formula is (y2-y1)/(x2-x1) so if you plug in the numbers given into that formula you get (3-4)/(7-10), then simplifying that you get (-1)/(-3) and the negatives cancle out so you get 1/3
The slope is the inclination of a line and can be calculated by the ratio of the difference of y's coordinate to x's coordinate thus the slope of the line passing through points (10,4)and (7,3) is 1/3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines . The slope could be positive or negative.
The slope of the lines passing through points (x₁, y₁) and (x₂, y₂) is,
⇒ (y₂ - y₁)/(x₂ - x₁)
As per the given points (10,4)and (7,3)
Slope = (3 - 4)/(7 - 10)
Slope = -1/-3 = 1/3
Hence "The slope is the inclination of a line thus the slope of the line passing through points (10,4)and (7,3) is 1/3".

On Tuesday afternoon at camp, Tiana did archery and sailing before dinner. Archery started at 12:30 P.M. Tiana spent 55 minutes at archery and 55 minutes sailing. What time did sailing end?
Answers
Answer:
2:20 p.m.
Step-by-step explanation:
Let's start with what we know
Tiana starts at 12:30 and spends 55 minutes at archery and 55 minutes sailing.
This question wants us to find what time does sailing end. To find this, we add 12:30 with 55 minutes for archery, then another 55 minutes for sailing
So,
12:30 + 55 minutes = 1:25
Then,
1:25 + 55 minutes = 2:20
So, she will end sailing at 2:20 p.m.

Explain why the work is not correct.
Answers
Where
y is the y of (2, -8)
x is the x of (2, -8)
m is the gradient or slope
c is the y intercept (you don’t know what it is)
Put into equation and find c
Once find c rewrite the equation with only the m and c in numbers
Eg
y = 5x + 3 (this is an example not the answer)
Hope this is helpful if you don’t understand please comment
Point slope form: y - y1 = m (x - x1)
Used when given one point and a slope (m)
(2, -8) and a slope of -6
y - y1 = m (x - x1)
y - (-8) = -6(x - 2)
y + 8 = -6x + 12
- 8 - 8
y = -6x + 4
Check your answer using (2, -8):
y = -6x + 4
-8 = -6(2) + 4
-8 = -12 + 4
- 8 = -8
This statement is true.
Another way to explain why they are incorrect:
y - (-8) = -6(x - 2)
y + 8 = -6x + 12 (This is where they went wrong. Two negatives next to each other when subtracting, make a positive)
y + 8 = -6x + 12
- 8 - 8
y = -6x + 4
