Answer:
a; d = 20n
Step-by-step explanation:
you can use the process of elimination and an example problem to help!
so if mason mowed 2 lawns, he'd make $40, right? now you could try each equation to see which one equals $40
a. d = 20(2) ⇒ d = 40
b. n = 20d ⇒ 2 = 20d ⇒ d = 0.1
c. d = 20 ÷ n ⇒ d = 10
d. n = 20 + d ⇒ 2 = 20 + d ⇒ d = -18
therefore, your answer would be A!

You have a hemisphere with a volume of 6. What is the surface area with a sphere with the same diameter. Round to the nearest thousandth.
Answers
Answer:
(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)
For a sphere of radius R, the volume is:
V = (4/3)*pi*R^3
Where pi = 3.14
And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:
V = (1/2)*(4/3)*pi*R^3
We know that the volume of the hemisphere is 6 m^3, then we have the equation:
6 m^3 = (1/2)*(4/3)*3.14*R^3
Now we can solve this for R.
6 m^3 = 2.1*R^3
∛(6 m^3/2.1) = R = 1.41 m
The radius of the hemisphere is 1.41m
Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)
For a sphere of radius R, the surface is:
S = 4*pi*R^2
Then the surface of this sphere is:
S = 4*3.14*(1.41 m)^2 = 24.971 m^2

Answers
Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°

Timothy spent 1 hour 22 minutes less than Bill reading last week. Bill spent 47 minutes less than Pete. Pete spent 3 hours reading. How long did Timothy spend reading?
Answers
Answer: 51 minutes
Step-by-step explanation:
Firstly, Pete spent 3 hours reading. Bill spent 47 minutes less than Pete reading so Bill spent:
= 3 hours - 47 minutes
= 2 hours 13 minutes
If Bill spent 2 hours 13 minutes reading and Timothy spent 1 hour 22 minutes less than this, the amount of time that Timothy read for was:
= 2 hours 13 minutes - 1 hour 22 minutes
= 51 minutes
If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?
A. Y= 144/x
B. Y= 16/x
C. Y= x/16
D. Y= x/144
Answers
Answer:
A. Y = 144/x
Step-by-step explanation:
Inversely means y = 1/x
If y = 48, when x = 3
so 144/3 = 48
Therefore the answer is A
If the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
What is a function?A relation is a function if it has only One y-value for each x-value.
If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.
To find k, we can use the given values of y and x:
y = k/x
48 = k/3
k = 144
Now that we know k, we can write the function that represents the relationship between x and y:
y = 144/x
Therefore, if the value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

Answers
Answer:
11699 square centimeters
Step-by-step explanation:
In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.
When given two sides of a triangle and an angle, the area of the triangle is calculated as:
1/2jksintheta
theta = 173°
Hence:
Area of triangle =
1/2 × 800 × 240 × sin 173
= 11699.456967 square centimeters
Approximately = 11699 square centimeters

Lily and Wilder live 810 miles apart. If they leave at the same time and drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph, after how many hours will they meet?
Answers
Given:
Distance between Lily and Wilder = 810 miles
They drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph.
To find:
After how many hours will they meet?
Solution:
Lily driving at 55 mph and Wilder driving at 80 mph towards each other. So, the relative speed is:
Relative speed [tex]=(55+80)\text{ mph}[/tex]
[tex]=135 \text{ mph}[/tex]
We know that,
[tex]Time=\dfrac{Distance}{Speed}[/tex]
[tex]Time=\dfrac{810}{135}[/tex]
[tex]Time=6[/tex]
Therefore, Lily and Wilder will meet after 6 hours.
