The distance formula is:
D = sqrt((x2-x1)^2 + (y2-y1)^2)
D= sqrt ((6-2)^2 + (8-1)^2)
D = sqrt(4^2 + 7^2)
D = sqrt( 16 + 49)
D = sqrt(65)
D = 8.06
Rounded to the beat tenth = 8.1 units.
The answer is C. 8.1 units
If the first set began to increase, than the other set tends to decrease.
Answer:
- 7y +3 =-25
-7y=-25—3
-7y=-28
-7y÷-7= -28÷-7
y=4
Step-by-step explanation:
Take +3 to the side so that your variable and a constant is on their own sides. When a number goes over the equals sign the sign changes at becomes the inverse that's why l said - 3. You now calculate - 25—3 equals 28 then divide by 7 to find y and your y is 4.
Answer:
25
Step-by-step explanation:
The first number in the range 1 - 50 that is divisible by 2 is 2 itself. Then 4, 6, 8, ....
Here's one way to think and count:
In the table, the number on the right is <u>half</u> the number on the left. The numbers on the right are just counting numbers (natural numbers), so there are 25 even numbers between 1 and 50.
Answer:
15
Step-by-step explanation:
To find how many she bought, we have to divide. So we do 105/7=15.
