Graph the line with the slope 1/3 that contains the point (-4, -3)
Answer:
So, 1 point is on (-4, -3)
Other point is on (-4, -7)
Step-by-step explanation:
Slope = y/x - y1/x1
=> -3 / -4 - ? = 1/3
=> -3 / -4 - 1/3 = ?
=> -3 -1 / -4 - 3
=> -4 / -7
So, -3 / -4 - (-4 / -7)
=> -3 +4 / -4 + 7
=> 1/3
So 1 point is on (-4 , -3)
Other point is on (-4, -7)

Mathematics, probability and chance Can somebody help me, I always thank and vote
Answer:
A. 0
Step-by-step explanation:
In order for there to be a 1 in 3 chance, there would have to be an equal number of the three chalices. Since four is the smallest number, the other two must have four left as well. That means Donavan drank 1 spoiled milk and 2 flat sodas. Therefore, he drank 0 purified water.
The steepness or grade of a road is expressed as a percent. if a road rises 6feet for every 24 horizontal feet. What is the slope of the road? what percent grade is this ?
Answer:
25%
Step-by-step explanation:
The ratio of rise to run is ...
rise/run = 6 ft/24 ft = 1/4
Expressed as a percentage, this is ...
1/4 × 100% = 25%
_____
Comment on this grade
Interstate highways are limited to a 7% grade. Most local jurisdictions limit the grade of a road to somewhere between 12% and 15%.
If you transform x2 + y2 = 25 into 4x2 + 4y2 = 25, which option below describes the effect of this transformation on the radius? A. It multiplies the radius by 2. B.It multiplies the radius by 4. C.It divides the radius by 4. D.It divides the radius by 2.
Answer:
C. It divides the radius by 4.
Step-by-step explanation:
We have x2 + y2 = 25.
If all terms were multiplied by 4, we would have 4x2 + 4y2 = 100. But, the radius is 25 units. 100 / 25 = 4. So, the radius was divided by 4.
Hope this helps!
Directions: Calculate the percent increase or decrease between the starting and ending
quantities below. Round your answer to one decimal place.
1. Start: 3
End: 10
2. Start: 9

I'll do the first two to get you started
===============================================
Problem 1
A = 3 = starting value
B = 10 = ending value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (10-3)/3 ] * 100%
C = (7/3) * 100%
C = 2.3333333 * 100%
C = 233.33333%
C = 233.3%
The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.
Answer: 233.3% increase===============================================
Problem 2
A = 9 = start value
B = 20 = end value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (20-9)/9 ] * 100%
C = (11/9)*100%
C = 1.2222222222*100%
C = 122.22222222%
C = 122.2%
Answer: 122.2% increasePlease help me with this question. I need to submit today. Question number 4. Lhakpa is a name of the person.
Answer:
Known:
width: 1/3
length: 3/5
Ask:
the area of floor?
Solution:
We need to multiply the width and length first!
width × length
= 1/3 × 3/5
= 3/15
= 1/5
Next subtract the number of floor witch has full fraction 1/1, so
= 1/1 - 1/5
= 5/5 - 1/5
= 4/5
So, the area of the floor is 4/5

Help, please show work
Answer:
132
Step-by-step explanation:
If US bisects the angle then
BUS = SUL
2x+10 = 3x-18
Subtract 2x from each side
2x+10 -2x = 3x-18-2x
10 = x-18
Add 18 to each side
10+18 =x
28 =x
We want to find BUL
BUL = BUS + SUL
2x+10 + 3x-18
5x-8
5*28 -8
140-8
132
Answer:
m<BUL=132
Step-by-step explanation:
Since US bisects <BUL, we know that <BUS ≅ <SUL
This is based on the angle bisector definition.
Hence, we can set up an equation to solve for x.
<BUS≅<SUL
2x+10=3x-18
Subtract 10 from both sides
2x+10-10=3x-18-10
2x=3x-28
Subtract 3x from both sides
2x-3x=3x-3x-28
-x=-28
Divide both sides by -1
x=28
m<BUL is the sum of m<BUS and m<SUL
m<BUL=m<BUS+m<SUL
m<BUS=2x+10
m<SUL=3x-18
Plug it in
m<BUL=2x+10+3x-18
Combine like terms
m<BUL=5x-8
Plug in 28 for x
m<BUL=5(28)-8
m<BUL=140-8
m<BUL=132
The Varners live on a corner lot. Often, children cut across their lot to save walking distance. The children’s path is represented by a dashed line. Approximate the walking distance that is saved by cutting across their property instead of walking around the lot. Hypotenuse: 32 ft , Short leg: x , Long leg: x+6
Answer:
[tex]x= \sqrt{503}-3[/tex]
Step-by-step explanation:
Hypotenuse = 32 feet
Short leg = x
Long leg = x+6
We will use Pythagoras theorem
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex]32^2=x^2+(x+6)^2[/tex]
[tex]1024=x^2+x^2+36+12x[/tex]
[tex]2x^2+12x-988=0[/tex]
[tex]x=-3-\sqrt{503}, \sqrt{503}-3[/tex]
Since the distance cannot be negative
So,[tex]x= \sqrt{503}-3[/tex]
If g (x) is the inverse of f (x) and f (x) = 4 x + 12, what is g (x)
g (x) = 12 x + 4
g (x) = one-fourth x minus 12
g (x) = x minus 3
g (x) = one-fourth x minus
Answer:
[tex]g(x) = \frac{1}{4} x - 3[/tex]Step-by-step explanation:
Since g(x) is the inverse of f (x) to find g(x) must first find f-¹(x)
To find f-¹(x) equate f(x) to y
That's
f(x) = y
y = 4x + 12
Next interchange the terms x becomes y and y becomes x
That's
x = 4y + 12
Next make y the subject
4y = x - 12
Divide both sides by 4
[tex]y = \frac{1}{4} x - 3[/tex]Therefore
[tex]g(x) = \frac{1}{4} x - 3[/tex]Hope this helps you

Two birds start from the same nest and head off in opposite directions. The speed of the first bird is 15mph more than the speed of the second.After 6 hours the two birds are 402 miles apart. Find the speed of each bird?
Answer: Speed of first bird =41 mph
Speed of second bird = 26 mph
Step-by-step explanation:
Let x be the speed of the second bird, then the speed of first bird will be x+15.
After 6 hours ,
Distance covered by first bird= (x+15)(6) [Distance = speed × time]
= 6x+90
Distance covered by second bird= (x)(6) = 6x
After 6 hours the two birds are 402 miles apart.
[tex]\Rightarrow\ 6x+90+6x=402\\\\\Rightarrrow\ 12x=402-90\\\\\Rightarrow\ 12x=312\\\\\Rightarrow\ x=\dfrac{312}{12}\\\\\Rightarrow\ x=\dfrac{312}{12}=26[/tex]
Speed of second bird = 26 mph, Speed of first bird = 26+15 = 41 mph.
A state highway department uses a salt storage enclosure that is in the shape of a cone, as shown above. If the volume of the storage enclosure is 48π m3, then what is the diameter of the base of the cone, in meters?
Answer:
Diameter of the base of the cone = 8 meters
Step-by-step explanation:
State highway department uses a salt storage enclosure which is in the shape of a cone.
Height of the storage in conical shape = 9 meters
Volume of the storage = 48π m³
Let the radius of this conical storage = r meters
Formula to get the volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here 'r' is the radius of the base of the cone and 'h' is the height of the cone.
Therefore, Volume = [tex]\frac{1}{3}(\pi ) r^{2}(9)[/tex]
[tex]48\pi=3\pi r^{2}[/tex]
r² = [tex]\frac{48\pi }{3\pi }[/tex]
r = [tex]\sqrt{16}[/tex]
r = 4 meters
Since, diameter = 2r
= 2(4)
= 8 meters
Therefore, diameter of the base of the cone = 8 metres
This table shows values that represent a quadratic function.
What is the average rate of change for this quadratic function for the interval
from x= 1 to x= 3?
Answer:
D. -4
Step-by-step explanation:
Using the general formula, [tex] m = \frac{f(b) - f(a)}{b - a} [/tex] , average rate of change for the quadratic function from x = 1 to x = 3, can be calculated as shown below:
Where,
[tex] a = 1, f(1) = -2 [/tex]
[tex] b = 3, f(3) = -10 [/tex]
Plug in the above values in the average rate of change formula:
[tex] m = \frac{-10 - (-2)}{3 - 1} [/tex]
[tex] m = \frac{-10 + 2}{2} [/tex]
[tex] m = \frac{-8}{2} [/tex]
[tex] m = -4 [/tex]
Average rate of change is D. -4

A building 50ft tall is on top of a hill A surveyor is at a point on the hill and observes that the angle of elevation to the top of the
building measures 48° and to the bottom of the building is 20°. How far is the surveyor from the bottom of the building?
Answer:
48-20
Step-by-step explanation:
The distance of the surveyor from the bottom of the building is 125.1 feet.
What is the angle of elevation?You look straight parallel to the ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called the angle of elevation.
Assume the distance of the surveyor from the bottom of the building is represented by x.
First, we have to know that the Tan of 48° is equal to 1.11.
The equation to get the distance will then be;
tan(48) = 50/h
h = 45.05 feet
Now, tan(20) = 45.05 /x
x = 45.05 / 0.36
x = 125.1 feet
The distance of the surveyor from the bottom of the building is 125.1 feet.

Any rectangle is also a parallelogram (but not the other way around). So AB is parallel to CD. The angles BAC and ACD are alternate interior angles that are congruent due to the parallel sides mentioned.
(angle BAC) = (angle ACD)
3x+4 = x+28
3x-x = 28-4
2x = 24
x = 24/2
x = 12
So,
angle BAC = 3x+4 = 3*12+4 = 40 degrees
and
angle CAD = 90 - (angle BAC) = 90 - 40 = 50 degrees
With any rectangle, the four interior angles are always 90 degrees. So that's why angles BAC and CAD add to 90.
