The hypotenuse of a right triangle is 65 cm, if one of its sides is 25 cm, find the length of the other side and it's perimeter
I will name you brainless if you give correct answer
Answers
Answer:
Other side = 60
Perimeter = 150
Step-by-step explanation:
Using Hypothenuse formula
25²+B²=65²
625+B²=4225
B²=4225-425
B²=3600 (Bring Square to the other side to become Square root)
B=√(3600)
B=60
Perimeter:(Sum of all side)
60+65+25
150

Answer:
(B) 4
Step-by-step explanation:
Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...
3 + 8 = 11
This tells you A = 8, so the top number is 1983, and the middle number is B78.
Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...
1 + 9 + B = <something ending in 4>
We know the something cannot be 04 or 24, so must be 14. Then ...
10 + B = 14 ⇒ B = 4
__
So, the whole sum is ...
1983 +478 = 2461
and the letter values are ...
A = 8B = 4D = 2Answer:
B is 4.
Step-by-step explanation:
If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8. Therefore A = 8.
Now we move to the tens place, since we know A is 8 we can substitute it there. Don't forget to add the one from the 11 we got. 1+8+7 = 16
Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.

Answer: y=5
Step-by-step explanation:
The line only has a value of 5, regardless of the value of x. So the slope of this line is "o," the vlaue of x has no influence on the value of y.
y = mx + b
y = ox + b
b is the y-intercept, the value of y when x = 0. That would be 5, again:
y = 0x + b
y = b
y = 5
Explanation:
Because on a linear graph the equation is y=x so with this specific graph the line goes horizontally on (5,0) so applying that to the equation its y=5

Next find your b-value, your y-intercept: (0,-2). For the slope-intercept form, you only need the -2 as your b-value.
Putting that together into slope-intercept form, y=mx+b, you’d have an equation of y = -5/6 x - 2.

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes.
What integer represents the rate of motion of the submarine?
–
feet per minute
Answers
Okay so our starting point is - 1,260 feet
Now it is descending (-) 5 ft per minute for 12 minutes
So we multiply -5 (negative because it is descending) by 12
-5 x 12 = -60
So now we add -60 to -1,260
This would be -1,320
So the submarine's new position in relation to the sea level is -1,320
Hope this helped. Have a great day!
that would be -1260 + 12(-5) = -1260 - 60 = -1320 feet
