Find the probability of what?
Answer:
Yes
Step-by-step explanation:
It will be a right-angle triangle if it satisfies the pythagoras theorem
12.5² = 156.25
10² = 100
7.5² = 56.25
Since 12.5² = 10² + 7.5²,
it is a right-angle triangle with 90° at C (because it's opposite the longest side, the hypotenuse)
Answer:-1\/4 (5 x + 3) is one of them and the other is
1\/4 (-5 x - 3) but the first has negative
Step-by-step explanation:
Answer:
45.3 grams will be left
Step-by-step explanation:
Use the formula
A = P(1 - r)^t where A is the final amount, P is the initial amount, r is the percent change as a decimal, and t is the amount of time
Plug in what we know, we are given P = 780, r = 0.163, and t = 16
A = 780(1 - 0.163)^16
Now simplify...
A = 780(0.837)^16
A = 45.25868493
A = 45.3
Step-by-step explanation:
∠2 and ∠7 are alternate exterior angles so they are equal.
So you can create the equation
40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.
20x = 100
x = 5
if you need m∠2 Substtute 5 for x in 20x+52
20(5) + 52 = 100 +52 m∠2= 152°
m∠7 40(5) - 48 = 200-48 m∠7= 152°
