Find the midpoint of the segment with the endpoints:(1, 7) and (9,0)
Answer:
The midpoint is (5,3.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
( 1+9)/2 = 10/2 =5
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
( 7+0)/2 = 7/2 =3.5
The midpoint is (5,3.5)

Which expression is equivalent to 5^10 x 5^5?
5^2
5^5
5^15
5^50
Answer:
5^15
Step-by-step explanation:
5^5 is 3125, and 5^10 is 9765625. When multiplied, you get 30517578125. 5^5 is in the equation, so that couldn't be the answer. 5^50 is too big of a number, so that also wouldn't work. 5^2 is 25, and that would be too small. That leaves 5^15, which when calculated leads to 30517578125.
Answer:
5^15
Step-by-step explanation:
5^10 is equivalent to 9765625 and 5^5 is equivalent to 3125. 9765625x3125 is equal to 30517578125. We need to find the expression wich is equal to that number. It can't be 5^2 (25), 5^5 (3125), 5^50 (8.8817842e+34). The answer is 5^15 (30517578125)

Irrational: √20, √3, √14
__
The square root of a perfect square, such as √121 = √(11^2) = 11, is rational. The square root of any integer that is not a perfect square is irrational.
Any fraction or finite-length decimal number is rational. Any repeated decimal is also rational, regardless of the length of the repeat.

A seven digit telephone number is of the form ABC-DEFG. In one particular state, the digit ‘A' is restricted to any number between 1 and 9. The digits B and C are restricted to any number between 2 and 9. The digits D,E,F, and G have no restriction. How many seven digit phone numbers are possible with these restrictions?
Answer:
2,520,000
Step-by-step explanation:
We are told the telephone number has seven digits of the form ABC-DEFG
We are told that the digit ‘A' is restricted to any number between 1 and 9.
Between 1 and 9 means numbers in between 1 and 9. So 1 and 9 are not included.
This means the numbers include 2, 3, 4, 5, 6, 7, 8. Which means there are 7 ways to select.
We are also told that digits B and C are restricted to any number between 2 and 9
This means that the numbers are; 3, 4, 5, 6, 7, 8. It means there are 6 ways to select.
Now, we are told that digits D,E,F, and G have no restriction. Thus, there are 10 ways to select each digit.
To find the Number of seven digit phone numbers that are possible with these restrictions, we will multiply each individual number of ways for each digit.
Thus;
Probability = 7 × 6 × 6 × 10 × 10 × 10 × 10 = 2,520,000

Answer:
Picture 1: 40 degrees
Picture 2: 90 degrees
Picture 3: 65 degrees
Picture 4: 85 degrees
Step-by-step explanation:
(2x-5) + (x+25) + (x) = 180
4x=160, x=40
180-90 = 90
2(65)+12+38 = 180
2x=40, x=20
6(20)-25 = 95
180-95 = 85

D
Answer:
c
Step-by-step explanation:
most energy don't enter the ecosystem through sunlight, there's water too, and air
The energy is recycled after flowing through ecosystems is not true, So option b is the correct answer.
The energy flow in the ecosystem is one of the most important factors for the survival of such a large number of organisms.
What is an ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. The ecosystem has two main components which are biotic and abiotic. They are connected through nutrient cycles and energy.
From the sunlight as a source of energy, it enters the system through photosynthesis. So, the energy is transferred between organisms. energy flows take place through the food chain and food web, which is not recycled in ecosystems and requires a continuous input of energy to sustain. Thus, the energy flow is unidirectional.
Therefore, b is the correct option that energy is recycled after flowing through ecosystems.

20 days, how many students have gone out of the hostel ?
plzzzzzzzzzzzzzz tell me answer now I need help
Given :
A hostel of 500 boys has provisions for 4 days.
To Find :
If the provisions were continued for 20 days, how many students have gone out of the hostel.
Solution :
Let, number of students left after 20 days are x.
Now, provisions are given by :
[tex]\text{Provisions = Number of students}\times \text{Number of days}[/tex]
Also, provisions remains same.
So, initial provision = final provision
[tex]500\times 4 = x \times 20\\\\x=100[/tex]
Therefore, 100 students have gone out of the hostel.
Hence, this is the required solution.
