A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Answers
Answer:
1,050 years
Step-by-step explanation:
A comet passes Earth every 70 years.
Another comet passes Earth
every 75 years
If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Find the lowest common multiple of 70 years and 75 years
70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,
75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350
Lowest common multiple of 70 years and 75 years is 1,050 years
Therefore,
If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

numerator : 24(15).x^5.y^8.z^7
denominator: 40(6).x^3.y^6.z^9
First, the numbers.
24(15)/[40(6)] = 3/2
Then x: x^5/x^3 = x^(5-3) = x^2
Then y: y^8/y^6 = y^2
Then z: z^7/z^9 = z^(-2) = 1/z^2
Result: [3.x^2.y^2]/(z^2)
Solve the following system of equation using the method of substitution. Show the work that leads to your
answer.
y=-2x-10
2x + 5y = 6
Answers
Answer:
Step-by-step explanation:
y = -2x - 10 ----------------------(I)
2x + 5y = 6 __________(II)
Substitute y = -2x - 10 in equation (II)
2x + 5 (-2x -10) = 6
2x + (-2x) *5 + (-10) *5 = 6
2x - 10x - 50 = 6
-8x - 50 = 6
-8x = 6 + 50
-8x = 56
x = 56/-8
x = -7
Plugin x = -7 in equation (I)
y = -2*(-7) - 10
= 14 - 10
y = 4

Answers
Answer:
2144.66 cubic inches
Step-by-step explanation:
The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.
What is the closest value of water in the Fishbowl in cubic inches?
From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.
This means we are to find the volume.
The volume of a sphere is given as:
4/3πr³
We are given Diameter of the fish bowl = 16 inches
Radius = Diameter/2 = 16 inches/2
= 8 inches
Hence,
Volume of the sphere (Volume of water) = 4/3 × π × 8³
= 2144.66 cubic inches

URGENTT!! Susan will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60 per mile driven. The second plan has an initial fee of $75 and costs an additional $0.10 per mile driven. How many miles would Susan need to drive for the two plans to cost the same?
Answers
Answer:
150 miles
Step-by-step explanation:
Let
x = number of miles
Plan A: 0.60x
Plan B: 75 + 0.10x
How many miles would Susan need to drive for the two plans to cost the same?
0.60x =75 + 0.10x
0.60x - 0.10x = 75
0.50x =75
x = 75/0.50
x = 150 miles
Susan needs to drive for 150 miles for the two plans to cost the same

10 pears and she sold 8..
10-8=2
she started with 10, so we multiply that by 5..
5 x 10 = 50
we add how many she had (2) to the ant she got in her shipment (50) to get our tots of 53 pears!

$31,500
Answers
Answer:
33,398
Step-by-step explanation:
So first you have to do 750x42 and that gets you 31,500 but then you have to pay the down payment so then it is 31,500+1,898 which gets you 33,398.

What is the end behavior of the function f(x) = 2* + 5?
Answers
Answer:o understand the behaviour of a polynomial graphically all one one needs is the degree (order) and leading coefficient. This two components predict what polynomial does graphically as gets larger or smaller indefinitely. This called "end behavior". For example it easy to predict what a polynomial with even degree and +ve leading coefficient will do. All even polynomial have both ends of the graph moving in the same direction with direction dictated by the sign of leading coefficient. On the other hand odd power will get have the polynomial end points moving in opposite direction, with the leading coefficient dictating the direction.

Step-by-step explanation:
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
