Answer: Swinging an arc from the first endpoint of the copied segment that comes directly after measuring the distance of the original segment
Answer:
large tank volume = 6 litres
small tank volume = 3 litres
Step-by-step explanation:
Given that,
The combined volume of 3 large tanks and 2 small tanks is 24 litres.
The combined volume of 2 large tanks and 3 small tanks is 21 litres.
Suppose large tank volume = x
Suppose small tank volume = y
<h2>First Equation </h2>
3x + 2y = 24
<h2>Second Equation </h2>
2x + 3y = 21
Now solve them
3x =24 - 2y
x = (24 -2y) / 3
Put value of x in second equation
2 {(24 -2y) / 3} + 3y = 21
2(8) - 4y/3 +3y = 21
16 - 4y/3 + 3y = 21
3y -4y/3 = 21-16
5y/3 = 5
5y = 15
y = 15/5
y = 3
3x = 24 - 2(3)
3x = 18
x = 6
Answer:
it may be wrong but this is what i think...
-80/16
Answer: C. (10, -10)
Step-by-step explanation:
Given
1) 2x-3y=50
2) 7x+8y=-10
Multiply both sides of 1) equation by 3.5
1) 3.5(2x-3y)=3.5×50
7x-10.5y=175
2) 7x+8y=-10
Subtract 2) equation from the 1)
(7x-10.5y)-(7x+8y)=175-(-10)
-18.5y=185
y=-10
x=10
(10, -10)
Hope this helps!! :)

Answer:
a. 3/40
b. 37/40
c. 2/39
d. 37/39
e. 3/39
h. 36/39
k. 1/260
m. 37/520
n. 37/520
w. 111/130
Step-by-step explanation:
First person:
a. 3/40
b. 37/40
_____
Second person:
left-handed branch of tree diagram: since the first person was left-handed, it means there is one less left-handed person, and one less person for the total
c. 2/39
d. 37/39
not left-handed branch of tree diagram: since the first person wasn't left-handed, there are still 3 left-handed people, and there is one less person for the total.
e. 3/39
h. 36/39
_____
for the final probabilities, just multiply along the tree branches:
k = a × c = 1/260
m = a × d = 37/520
n = b × e = 37/520
w = b × h = 111/130
