a= 27
Answer:
1/4(x+2) = 3
Step-by-step explanation:
Let's do this one thing at a time.
1/4 of a number means 1/4 times a number. We'll use x to represent "a number," so we have
1/4x
But wait: we need to add 2 to a number (sum = addition). So we have
1/4(x+2)
This is three, so we know that expression is all equal to 3.
1/4(x+2) = 3
Answer:
c maybe i can barely read it :(
Step-by-step explanation:
The probability that two of the coins will be tails is 1/2
It is 1/2 because "at least two tails" means that two tails and the rest of the number of tails, which is 3. In total the three coins have 6 sides. The chance of having two tails and one is three out of 6, simplified is 1/2 ;)
Answer:
The value of height of the building h = 509.2 feet
Step-by-step explanation:
From the Δ A B C
⇒ h = y 
° ------- (1)
From Δ A B D
⇒ h = ( y + 300 ) 
° ------- (2)
Equation 1 = Equation 2
⇒ y ° = ( y + 300 ) °
⇒ 0.46 y = 0.36 y + 109.2
⇒ 0.1 y = 109.2
⇒ y = 1092 feet
Put this value of y in equation ( 1 ) we get,
⇒ h = 1092 × tan 25°
⇒ h = 509.2 feet
This is the value of height of the building.
